Description

Open-width textile structures

Technical Field

The present invention relates to open-width textile structures, particularly for automotive applications. ) and corresponding methods of making open-width textile structures.

Background Art

It is known and common in the prior art to provide electrical lines or electrical accumulators with sheathing in motor vehicles (assuming a vehicle with an internal combustion engine, an electric motor or a hydraulic drive train).

The sheath protects the wires/storage devices from damage in the event of an accident, for example to reduce the risk of fire. In order for them to be able to perform the functions described, the sheaths are made of mechanically stable materials. This results in an increase in vehicle weight and also in the fact that such sheaths can only be laid poorly due to their lack of flexibility.

For this reason, the prior art has focused on materials that are relatively light and offer a high degree of flexibility when laying out the sheath. For example, textile materials made of aramid fibers, which are known for their good impact resistance, have been used for sheaths. However, the problem here is the price and availability at the time, since aramid fibers are in great demand for ballistic applications.

Summary of the invention

Against this background, the object of the present invention is to provide a flat-width textile structure, in particular for automotive applications, which is relatively light on the one hand and provides good mechanical protection on the other hand. The object of the present invention is at least to provide one or more alternatives to the prior art.

The open-width textile structure is preferably a woven fabric having an open-width woven body. ), a flat-width woven body is formed by a first yarn group consisting of longitudinal yarns extending in the longitudinal direction of the flat-width woven body and a second yarn group consisting of transverse yarns extending in the transverse direction of the flat-width woven body, wherein the first and second yarn groups are interconnected/combined by respective longitudinal yarns and transverse yarns, so that a force deflection structure extending in the transverse direction is i. formed alternately on one side and the other side of the flat-width woven body in a longitudinally offset manner, or ii. formed on one side of the flat-width woven body in a longitudinally offset manner, wherein the respective force deflection structure is provided in such a way that when it is subjected to force, especially in the normal direction of the flat-width woven body, it causes force deflection to at least the longitudinal direction of the flat-width woven body.

A flat-web textile structure is, for example, a large-area wide-web woven fabric which is suitable, for example, for protecting the outer wall of an electrical storage device.

Alternatively, the flat-width textile structure can be a narrow strip with which, for example, automotive electrical wires can be sheathed by placing the narrow strip on the electrical wires and wrapping them around them. The longitudinal direction of the flat-width textile structure and the longitudinal axis of the electrical wires preferably coincide in this case.

The open-width textile structure ends at its outer edges extending in the longitudinal direction, for example with a selvedge or a knitted selvedge.

Preferably, the open-width textile structure can be woven in such a way that it forms a tube. Particularly preferably, the longitudinal threads and transverse threads of the tube have elastic properties so that the tube can be expanded radially.

The offset between the force deflection structures is, for example, 3 mm to 8 mm.

Preferably, the open width textile structure is designed into a woven fabric, wherein the longitudinal yarns of the first yarn set are warp yarns and the transverse yarns of the second yarn set are weft yarns.

The flat-width textile structure is preferably designed in such a way that the longitudinal yarns and transverse yarns of the first and second yarn groups are interconnected/combined in such a way as to at least partially form the respective force deflection structures, i.e. a weave (Bindungsmuster) is produced in which at least one first longitudinal yarn extends above two lower transverse yarns and below at least one upper transverse yarn, which is located in the longitudinal direction between the two lower transverse yarns.

The two lower transverse threads are preferably weft threads, which are adjacent to the upper transverse threads or upper weft threads. That is, the upper weft thread forms the xth weft thread among the n weft threads, and the two lower weft threads are the (x-1)th and (x+1)th weft threads.

The first longitudinal yarn is preferably one of the warp yarns. The warp yarn loop, which is repeated here with respect to the weaving sequence of the warp yarns formed by the warp yarns, preferably contains only one first longitudinal yarn/warp yarn or two first longitudinal yarns/warp yarns. The warp yarn loop preferably contains four longitudinal yarns/warp yarns.

The open-width textile structure is preferably designed in such a way that each force deflection structure is designed to move the upper transverse thread toward the two lower transverse threads when it is subjected to force, so that the first longitudinal thread is subjected to tensile forces in the longitudinal direction.

When the upper transverse yarn/weft yarn moves toward the two lower transverse yarns/weft yarns, the upper transverse yarn/weft yarn is pressed between the transverse yarns below it and pulls the first longitudinal yarns forming the cushion layer, thereby causing this or these first longitudinal yarns/warp yarns to be subjected to tension.

The flat-width textile structure is preferably designed in such a way that the longitudinal yarns and transverse yarns of the first and second yarn groups are interconnected/combined in such a way as to at least partially form a force deflection structure, i.e., a weave is produced in which at least one second longitudinal yarn extends below two lower transverse yarns and above at least one upper transverse yarn, which is located between the two lower transverse yarns in the longitudinal direction.

The flat-width textile structure is preferably designed in such a way that the longitudinal yarns and transverse yarns of the first and second yarn groups are interconnected/combined in such a way as to at least partially form a force deflection structure that a weave is produced in which a third longitudinal yarn extends below the two lower transverse yarns and above two further lower transverse yarns, with the further two transverse yarns being located between them in the longitudinal direction.

The two further lower transverse threads are preferably weft threads which are adjacent to the two lower transverse threads/weft threads. That is, one of the further lower transverse threads forms the xth weft thread and the other forms the yth weft thread, where x>y applies, and the two lower transverse threads/weft threads are then the (x-1)th weft thread and the (y+1)th weft thread.

The open-width textile structure is preferably designed such that the transverse threads of the second thread group are arranged in a straight line in the longitudinal direction as viewed in the transverse direction of the open-width woven body or are arranged in a zigzag or wavy shape in a plane defined by the thickness direction and the longitudinal direction of the open-width woven body.

The arrangement of the transverse threads/weft threads in a straight line in the longitudinal direction preferably occurs when the open-width textile structure or the open-width woven body is wound up or woven as a tube.

In particular, a zigzag arrangement of the transverse threads/weft threads is present when the flat-width textile structure is a wide fabric or a narrow tape.

Preferably polyester filaments, for example 1670 dtex F192/Z60 polyester filaments HT/NS, are used for the longitudinal threads/warp threads and/or transverse threads/weft threads of the flat-width textile structure, preferably in the form of narrow strips, tubes or wide fabrics.

The longitudinal yarns/warp and/or transverse yarns/weft of the flat-width textile structure, preferably in the form of narrow tapes, tubes or wide fabrics, can be composed of high-strength polyester fibers and aramid fibers (continuous fibers or short-cut fibers), glass fibers, carbon fibers or high-performance fibers such as PPS fibers, PEEK fibers. The longitudinal yarns/warp can be, in particular, monofilaments as well as multifilaments or combinations thereof.

Particularly preferably, the transverse threads/weft threads consist of 0.30 mm polyester copolymer and 0.25 mm polyester. Particularly preferably, the transverse threads/weft threads have a greater thickness/thickness than the longitudinal threads/warp threads.

The longitudinal threads/warp threads may be a combination of the aforementioned materials, ie several of the longitudinal threads/warp threads may consist of a material different from that of the other longitudinal threads/warp threads.

The same preferably applies to transverse threads/weft threads, provided that, for example, a weft change can take place in the following production method.

If the open-web textile structure is provided, for example, in a cylindrical form for simultaneous insulation of electrical wires, a crimped 1340 dtex polyester can be used for this purpose.

However, other yarn strengths, yarn qualities or combinations are also conceivable, and other materials such as, for example, polyamide or recycled fibers can also be used for the longitudinal threads/warp threads and/or transverse threads/weft threads.

The method according to the invention for producing an open-width textile structure, preferably a woven fabric, comprises the following steps:

The open-width woven body is formed by connecting/combining a first yarn group consisting of longitudinal yarns extending in the longitudinal direction of the open-width woven body and a second yarn group consisting of transverse yarns extending in the transverse direction of the open-width woven body, thereby forming the open-width woven body,

The first yarn group and the second yarn group are connected/combined with each other through respective longitudinal yarns and transverse yarns, that is, the force deflection structure extending in the transverse direction

i. respectively, alternately formed on one side and the other side of the flat-width woven body in the longitudinal direction and staggered, or

ii. are formed on one side of the flat-width woven body in a longitudinally offset manner, wherein,

In this case, the respective force deflection structure is provided in such a way that, when it is subjected to force, it causes a deflection of the force at least in the longitudinal direction of the flat-width woven body.

The method is preferably carried out on a weaving machine, in which the longitudinal threads form the warp threads and the transverse threads form the weft threads. In particular, a weaving machine is used to weave a narrow band or a tube. The weaving machine housing contains a weft insertion needle, which inserts the yarn loop into the shed formed during the weaving process. For this reason, the weft threads in the open-width woven body, the narrow band or the tube are respectively double weft threads according to the technology and are connected to each other on the side facing the weft insertion needle before the weft insertion.

The latch needle is on the side facing away from the weft insertion needle, and the latch needle interacts with the yarn loop to form a loop that constitutes the edge (knitting edge). The edge facing the weft insertion needle is preferably formed by shed change and is therefore a selvedge.

In addition to the weft insertion needle, the weft loom can also have another weft insertion needle, which is arranged on the same side of the warp yarn or the formed shed. The weft insertion needle and the other weft insertion needle can preferably work synchronously and preferably place a corresponding yarn loop into the formed shed respectively. In the corresponding shed, there are two weft threads, which are always double weft threads due to technical reasons. The latch needle can interact with two yarn loops or an independent latch needle can be provided for each weft insertion needle.

Alternatively, the weft insertion needle and the further weft insertion needle may be arranged on opposite sides of the narrow band/tube. This type of weaving machine is also known as an X-type weaving machine.

In this case, the two weft insertion needles can insert their respective yarn loops into the same shed, so that there are two double weft yarns in each shed, or work alternately in the sheds formed one after the other, so that in each shed there is a double weft yarn alternately coming from the weft insertion needle or another weft insertion needle depending on the technology.

If the weft insertion needles are arranged on opposite sides of the narrow band/tube, there is also a latch needle on each side, which interacts with the corresponding yarn loop guided through the shed to form a loop in order to form an edge (knitting edge).

The provision of a plurality of weft insertion needles is preferred in particular when different weft threads are used which consist of different materials and/or have different strengths.

The present invention and the method are not limited to weaving machines or X-type weaving machines. Other automatic looms can also be used, such as automatic shuttle looms, automatic projectile looms or automatic jet looms. In these other automatic looms, multiple weft insertions can also be performed on each shed and other edges can also be obtained in the alternative automatic looms.

The method according to the invention is preferably designed to obtain preferred embodiments of an open-width textile structure. In this regard, reference is made to the above explanations of preferred embodiments of an open-width textile structure.

Furthermore, the process of the invention may have a refining step in which the open-width textile structure acquires further desired properties.

For example, the finishing step can include a heat treatment step, in which the produced flat-width textile structure is preferably heated/treated by applying temperature. The application of temperature or the heat treatment leads to the consolidation of the flat-width textile structure. In addition, the finished flat-width textile structure shows little or no further shrinkage behavior under subsequent use and the temperature effects that occur.

Alternatively or additionally, the refining step may have a treatment step in which the open-width textile structure is treated with a substance, for example:

- the open-width textile structure can be immersed in the substance and preferably subsequently squeezed dry, and/or

-The substance is sprayed onto the open width textile structure.

The substances used in the treatment steps serve, for example, for flame retardancy and/or cut resistance and/or other purposes.

DETAILED DESCRIPTION

FIG. 1 shows a perspective view of a flat-width textile structure 10 according to a first preferred embodiment of the present invention.

The open-width textile structure 10 has a first yarn group 20 having a plurality of longitudinal yarns 1k, ..., mk extending in the longitudinal direction of the open-width textile structure 10. The longitudinal direction of the open-width textile structure 10 corresponds to a direction of the k-axis of the coordinate system shown in FIG.

Furthermore, the open-width textile structure 10 has a second yarn group 30 having a plurality of transversely extending transverse yarns 1s, ..., ns. The transverse direction of the open-width textile structure 10 corresponds to a direction of the s-axis of the coordinate system shown in FIG.

Overall, the yarn groups 20, 30 form an open-width woven body 12 that is flat in the longitudinal direction (k-direction) and the transverse direction (s-direction).

The d-axis of the coordinate system shown in FIG. 1 corresponds to the thickness direction of the open-width textile structure 10 or the open-width woven body 12 .

The open-width textile structure 10 or the open-width woven body 12 is preferably a woven fabric. Accordingly, the longitudinal threads 1k, ..., mk form the warp threads of the fabric, while the transverse threads 1s, ..., ns correspond to a weft thread of the open-width woven body 12, which is inserted into the fabric at the correspondingly marked position so that the transverse threads/weft threads 1s, ..., ns appear.

Particularly preferably, the flat-width textile structure 10 according to the invention is a woven narrow band (Band), which extends in the longitudinal direction accordingly.

Narrow ribbons are best made on a ribbon loom.

FIG1 schematically shows a weft insertion needle SEN of a ribbon loom. The weft insertion needle SEN places the weft thread in the form of a loop into the shed formed by the lifting of a warp thread 1k, ..., mk during the operation of the ribbon loom or when producing narrow ribbons. The weft insertion needle SEN is arranged beside the narrow ribbon and is activated in such a way that it passes through the shed from there.

After the insertion needle SEN has completely passed through the formed shed and has reached the corresponding opposite end of the shed with the weft thread in the form of a loop, a loop is formed there by means of a latch needle not shown in Figure 1. The loop is used to form a corresponding tape edge, which is located on the side facing away from the insertion needle SEN.

The latch needle can, for example, form a belt edge because it

i. A loop is formed by passing the weft yarn as a loop,

ii. The loops of weft yarn are tied with the supplied looping hook yarn,

iii. formed by a weft yarn passing through as a loop and at least one hook yarn, or

iv. Looping is performed by a weft yarn passed through as a yarn loop, at least one supplied hook yarn and a supplied mouth yarn (Sperrfaden).

Variant iii is preferred, in which a single hook yarn is used.

The tape edge formed by the latch needles is a knitted edge for technical reasons.

At one end of the formed shed facing the weft insertion needle SEN, the formation of the tape edge there is carried out by the shed change after the weft insertion needle SEN is withdrawn. The tape edge facing the weft insertion needle SEN is therefore a selvedge.

As is clear from the foregoing explanation, the weft yarns 1s, ..., ns shown in FIG. 1 are all double weft yarns because of the yarn loops, and the weft yarns 1s, ..., ns are connected to each other on the side facing the weft insertion needle SEN and thus form a selvedge.

The flat-width textile structure 10 according to the invention is not limited to being designed as a narrow strip, nor to the explained edges, selvedges and/or knitted edges.

For example, the flat-width textile structure 10 can be a large, planar wide fabric which is not produced on a weaving loom but on another type of automatic weaving loom, in which, for example, the weft thread insertion direction is changed and a different type of edge is obtained.

The tapes (or tubes as will be explained below) can also be manufactured using other types of automatic looms.

The longitudinal threads or warp threads 1k, ..., mk of the flat-width textile structure 10 of the present invention are connected or combined or woven with the corresponding transverse threads or weft threads 1s, ..., ns in such a way that a force deflection structure 40 extending in the transverse direction or the s-axis direction of the coordinate system is obtained. The force deflection structure 40 extends completely through the entire flat-width textile structure 10 in the transverse direction.

1 at preferably regular intervals according to the offset V. The force deflection structures 40 are preferably formed alternately on one side, the top side, and on the other side, the bottom side, of the flat-width textile structure 10 .

Alternatively, the force deflection structure 40 can be formed with a preferably ordered offset V on one side, ie the top side or the bottom side.

The offset or corresponding distance shown is, for example, 3 mm to 8 mm, particularly preferably 5 mm.

The force deflection structure 40 has the function and characteristic of deflecting the force to at least the longitudinal direction of the flat-width woven body 12 when the flat-width woven body 12 is subjected to force from the normal direction corresponding to the d-axis shown in FIG. 1 .

The flat-width textile structure 10 provides good protection for the covered object, such as cables or power batteries of a motor vehicle, by deflecting the forces.

The weave of the flat-width textile structure that creates the force deflection structure 40 is explained with reference to a) and b) of FIGS. 2 and 3 .

Fig. 2 shows a fabric cross section of the flat textile structure 10 of Fig. 1 , and Fig. 3 a) shows a corresponding positive weave design. The viewing direction corresponding to the positive weave design of Fig. 3 a) is indicated in Fig. 2 by arrows BLR.

The four longitudinal threads or warp threads 1k, ..., 4k shown in Figure 2 together form a warp thread repeat, which in Figure 3a) corresponds to columns 1 to 4. Figure 3a) also shows a second warp thread repeat in columns 5 to 8, from which the repetition of the weave associated with the warp threads 1k, ..., 4k can be seen.

The warp threads according to rows 9 and 10, as shown in FIG. 3 a), are used to form an edge; in the case of the explained narrow band, they are used to form the explained selvedge. In this regard, rows 9 and 10 are located on the side facing the weft insertion needle SEN, and the warp threads according to row 1 are located on the side facing away from the weft insertion needle SEN. The interlacing of rows 9 and 10 or the corresponding warp threads can be changed or can also be omitted.

In addition to the warp threads, Figure 2 also shows the weft threads explained with reference to Figure 1. For the sake of simplicity of illustration, they are not shown as double weft threads.

FIG. 2 contains a number of complete weft yarn loops consisting of weft yarns 1s, ..., 6s. Each row shown in FIG. 3 a) corresponds to one of the weft yarns 1s to 6s, and two repeated weft yarn loops are obtained from a total of 12 rows. Rows 1 to 6 and rows 7 to 12 each correspond to a weft yarn loop consisting of weft yarns 1s, ..., 6s.

In general, Fig. 3 a) shows four warp yarn loops and four weft yarn loops. Each box of the weave design diagram corresponds to an interlacing point, at which the warp yarns of the column cross with a weft yarn of the respective row. If a box is occupied, the warp yarns extend above the associated weft yarns, and if it is empty, the warp yarns extend below the associated weft yarns.

The warp thread 1k or the warp thread 3k preferably forms a first longitudinal thread or warp thread, which, according to the fabric cross section of FIG. 2 and the weave design according to FIG. 3 a), extends in the positive d direction above the transverse threads or weft threads 5s, 1s. Preferably, two warp threads 1k, 3k also extend above the weft threads 5s, 1s and each form a first longitudinal thread or warp thread. The weft threads 5s and 1s in this connection form two lower transverse threads.

The weft yarn 6s (row 6) located between the weft yarns 5s, 1s in the longitudinal direction (k axis) is placed on the first warp yarn 1k, 3k. If two warp yarns 1k, 3k extend above the two lower weft yarns 5s, 1s, the weft yarn 6s is therefore placed on the two warp yarns 1k, 3k.

The weft thread 6s forms an upper weft thread/transverse thread 6s as shown in FIG. 2 .

At the same time, the upper weft thread 6s corresponds to one tip of the corresponding force deflection structure 40. Only the warp thread 2k extends above the upper weft thread 6s according to the fabric cross section of FIG. 2 and the weave design according to FIG. 3 a).

The warp thread 2k is preferably the only warp thread in the warp thread loop shown, which has a direction above the upper weft thread 6s. The direction of the warp thread 2k is selected in relation to the adjacent weft threads 5s, 1s in such a way that it extends below the weft threads 5s, 1s, unlike the adjacent warp threads 1k, 3k. In this connection, FIG. 2 in conjunction with FIG. 3 a) shows the interlacing points according to the columns, rows 5 and 7. The warp thread 2k then floats until the adjacent force deflection structure 40 on the same side of the open-width woven body 12, where its direction is repeated.

Adjacent to the weft yarns 5s, 1s, the weft yarns 4s (row 4) and 2s (row 8) form two further lower weft yarns 4s, 2s. Therefore, the weft yarns 5s, 6s, 1s (rows 5 to 7) are located longitudinally between the two further lower weft yarns 4s, 2s.

The warp threads 1 k , 3 k extend below the further lower weft threads 4 s , 2 s according to the fabric cross section of FIG. 2 and the weave design according to FIG. 3 a ).

The remaining warp threads 4k belonging to the same warp thread loop extend through two further lower weft threads 4s, 2s according to FIG. 2 in conjunction with FIG. 3 a) and float between the weft threads 4s, 2s below the weft threads 5s, 6s, 1s.

The star marked in the rightmost force deflection structure 40 in FIG. 2 indicates that the weave results in a qualitatively represented spacing, i.e., the upper weft yarn/transverse warp yarn 6s, the two lower weft yarns/transverse yarns 5s, 1s and the other two lower weft yarns/transverse yarns 4s, 2s are located in respective different planes.

The open-width textile structure 10 according to Figures 1 and 2 is neither under tension nor under compression. In other words, Figures 1 and 2 show the open-width woven structure 10 or the narrow strip in an unstressed state.

As can be seen from Figures 1 and 2, the open-width woven body 12 is oriented due to the interweaving in such a way that the points shown in Figure 2, which indicate the weft yarns 1s to 6s, have a zigzag shape in the d-k plane.

If external forces act on the flat-width textile structure 10 in the illustrated thickness direction (d-axis), the force deflecting structures 40 exert the protective effect already mentioned, since they deflect the external forces into the longitudinal direction (k-axis).

The external force is redirected to the longitudinal direction in such a way that, when the force redirection structure 40 is subjected to an external force, the upper weft yarn 6s moves toward the two lower weft yarns 5s, 1s, whereby the warp yarns 1k, 3k (the first or multiple longitudinal yarns) are subjected to tension in the longitudinal direction. The lower weft yarns 5s, 1s serve as support for the warp yarns 1k, 3k.

The other lower weft yarns 4s, 2s serve as support for the warp yarns 4k, which float below the weft yarns 5s, 6s, 1s and form a cushion for them. If the weft yarns 5s, 6s, 1s are pressed onto the warp yarns 4k between the other lower weft yarns 4s, 2s, the external force is redirected to the longitudinal direction of the open-width woven body 12.

In Fig. 1 and Fig. 2, the flat-width woven body 12 is basically formed in a planar manner, that is, it extends in the s-k plane. As already explained, the flat-width woven body 12 is not limited to the narrow band shown, but can be formed in a large area. For example, such a large-area flat-width woven body 12 can protect the outer surface of the battery used as the power source of the automobile electric powertrain from external loads.

The narrow strips shown can protect smaller objects in a flat design or be used, for example, to sheath wires, in particular high-voltage wires. To achieve such sheathing of wires, it is preferred that the weft yarns 1s to 6s have such material-specific properties that they are twisted under thermal load or heating so that the flat-width woven body 12 is wrapped around the k axis to form a sheath.

Or the weft yarns 1s to 6s can have such material-specific properties that they become flexible/soft by heating, so that the soft flat-width woven body 12 can be wrapped to cover the wire. The weft yarns 1s to 6s cool down again after covering the wire, and the wrapped soft flat-width woven body 12 remains stable in shape.

Furthermore, the weft threads 1s to 6s can have the material-specific property that they can be bent without heating in order to sheath the electrical wire and then remain dimensionally stable.

After wrapping the open-width woven body 12, the weft yarns 1s to 12s are placed substantially on a horizontal straight line in the d-k plane. This arrangement is also present in the case of the tube explained below with reference to Fig. 4.

Fig. 3b) shows an exemplary drawing-in and an exemplary drawing-in reed, which are preferably selected when using the explained ribbon loom. The present invention is not limited to the drawing-in and drawing-in reed shown.

According to FIG. 3 b), eight heald shafts (rows 1 to 8 in FIG. 3 b) are provided, to which the warp threads of columns 1 to 8 according to FIG. 3 a) are fixed. Each of the eight warp threads of columns 1 to 8 according to FIG. 3 a) is assigned to one of the heald shafts and is fixed thereto. In addition, two heald shafts of rows 9 and 10 according to FIG. 3 b) are provided for forming selvedges, which are connected to the warp threads of columns 9 and 10 according to FIG. 3 a). In FIG. 3 b), the drawing-in of the weaving machine is shown repeatedly for six warp thread cycles. The illustration serves to explain the drawing-in.

The reed is very coarse and is selected so that the warp threads of two warp thread cycles, ie the warp threads of rows 1 to 8 according to a) of Figure 3, extend through the opening between two adjacent reed blades. To illustrate the drawing-in of the reed, the drawing-in heddle above it is shown again.

The flat-width textile structure 10 explained according to b) of Figures 1 to 3 can also be used to form a closed tube. For example, two flat-width textile structures 10 are woven for this purpose so that they jointly form a closed tube. This will be explained with reference to Figures 4 and 5.

FIG. 4 shows an upper flat-width textile structure 10 and a lower flat-width textile structure 10 ′, both of which are identical to the flat-width textile structure 10 of FIG. 1 to FIG. 3 b).

FIG. 4 shows two flat-width textile structures 10 and 10 'in a fabric cross section, wherein the orientation of the coordinate system is the same as in FIG. With respect to the upper and lower flat-width textile structures 10, 10 ', a weft thread cycle 1s to 6s or 1s ' to 6s ' is shown, respectively. Likewise, the corresponding warp threads 1k, 2k, 3k and, 4k and 1k ', 2k ', 3k ' and 4k ' are marked accordingly.

The weave patterns of the upper and lower flat-width textile structures 10, 10' are the same as those in Figure 2, and reference is made to the corresponding descriptions herein.

Fig. 5 shows the positive weave design of the woven tube of Fig. 4. The viewing direction BLR corresponding to the positive weave design is indicated in the figure by the arrow BLR.

Unlike a) in FIG. 3 , the weaving design diagram according to FIG. 5 does not show two warp yarn loops in columns 1 to 8, but rather shows one warp yarn loop of the upper flat-width textile structure 10 and one warp yarn loop of the lower flat-width textile structure 10 '. Columns 1 to 4 mark the four warp yarns 1k, ..., 4k of the upper flat-width textile structure 10, and columns 5 to 8 represent the warp yarns 1k', ..., 4k' of the lower flat-width textile structure 10 '.

Rows 1 to 12 represent weft yarns, wherein the even-numbered rows indicate weft yarns 1s,…,6s of a weft yarn cycle in the upper flat-width textile structure 10, and the odd-numbered rows indicate weft yarns 1s',…,6s' of a weft yarn cycle in the lower flat-width textile structure 10'.

The organization design diagram according to FIG. 5 also indicates the position of the weft yarn in such a way that when the weft yarn is located in the lower flat-width textile structure 10', all the interweaving points of the upper flat-width textile structure 10 are occupied, and when the weft yarn is located in the flat-width textile structure 10, all the interweaving points of the lower flat-width textile structure 10' are shown without color. The classification of the interweaving points that are occupied or shown without color when the weft yarn is located in each other flat-width textile structure comes from the viewing direction BLR (FIG. 4) corresponding to the organization design diagram of FIG. 5.

From the above description, it is known that the positive weave design diagram of Figure 5 shows the weft yarn cycle in the upper flat-width textile structure 10 and the weft yarn cycle in the lower flat-width textile structure 10', wherein the respective weave patterns are the same as the yarn cycle of a) in Figure 3. Therefore, refer to the description of a) in Figure 3.

The warp threads of rows 9 and 10 according to Figure 5 are used again to form a selvedge, which faces the weft insertion needle SEN. A knitted selvedge is formed on the other side facing away from the weft insertion needle SEN.

The upper flat-width textile structure 10 and the lower flat-width textile structure 10 'are connected to each other at the selvedge and the knitted edge, thereby obtaining a closed tube. In other words, the selvedge and the knitted edge are produced in such a way that the connection of the flat-width textile structures 10, 10 'is obtained.

Drawing in the heald and reed for forming the tube is the same as in b) of Figure 3, so refer to the relevant description.

A second preferred embodiment of the open width textile structure will now be explained with reference to FIGS. 6 and 7 .

FIG6 shows a fabric cross section of an open-width textile structure 100 according to a second preferred embodiment, wherein the fabric cross section corresponds to the d-k plane.

FIG. 7 shows the corresponding front view diagram, wherein the associated viewing direction BLR is shown in FIG. 6 .

The open-width textile structure has a first yarn group consisting of longitudinal yarns/warp yarns and a second yarn group consisting of transverse yarns/weft yarns. These yarn groups form a corresponding open-width woven body.

The longitudinal threads or warp threads 1k, ..., mk of the flat-width textile structure 100 of the present invention are connected or combined or woven with the corresponding transverse threads or weft threads 1s, ..., ns in such a way that a force deflection structure 140 extending in the transverse direction or s-axis direction of the coordinate system is obtained. The force deflection structure 140 extends completely through the entire flat-width textile structure 100 in the transverse direction.

6 at preferably certain intervals according to the offset V shown. Force deflection structures 140 are preferably formed alternately on one side, the top side, and on the other side, the bottom side, of flat-width textile structure 100 .

Alternatively, the force deflection structure 140 can be formed with a preferably ordered offset V on one side, ie on the top side or the bottom side.

The offset or corresponding spacing shown is, for example, 5 mm to 10 mm, particularly preferably 7 mm.

As in the first preferred embodiment, the force deflection structure 140 has the following function and characteristics, namely, when the open-width textile structure or open-width woven body is subjected to force from the normal direction corresponding to the d-axis shown in Figure 6, it causes the force to be deflected to at least the longitudinal direction (k direction).

The weave of the flat-width textile structure 100 that results in the force redirecting structure 140 will be explained with reference to FIGS. 6 and 7 .

The four longitudinal threads or warp threads 1k", ..., 4k" shown in Figure 6 together form a warp thread repeat, which corresponds to columns 1 to 4 in Figure 7. Figure 7 also shows a second warp thread repeat in columns 5 to 8, from which the weave repetition associated with the warp threads 1k", ..., 4k" can be seen.

The warp threads according to columns 9 and 10 shown in FIG7 are used to form an edge (selvedge or knitting edge). Columns 9 and 10 are located on the side facing the weft insertion needle SEN, and the warp threads according to column 1 are located on the side facing away from the weft insertion needle SEN. The interlacing of columns 9 and 10 or the corresponding warp threads can be changed or can also be omitted.

The open-width textile structure 100 can be a large-area structure (wide fabric) or a narrow strip as in the first embodiment. It can also be double woven to form a closed tube, as explained above.

Figures 6 and 7 contain a complete weft thread loop consisting of weft threads 1s", ..., 10s". Each row shown in Figure 7 corresponds to one of the weft threads 1s"-10s" of the weft thread loop. The weave pattern according to Figure 7 therefore contains a complete weft thread loop.

Preferably, the warp yarn 2k" (row 2) forms the first longitudinal yarn or warp yarn, which extends in the positive d direction above the transverse yarn or weft yarn 6s" (row 6) and 8s" (row 8) according to the fabric cross-section of Figure 6 and the organizational design according to Figure 5. The weft yarns 6s" (row 6) and 8s" (row 8) form two lower transverse yarns in this regard.

The weft thread 7s" (row 7) which is located between the weft threads 6s" (row 6) and 8s" (row 8) in the longitudinal direction (k-axis) lies against the first warp thread 2k.

The weft thread 7s" forms an upper weft thread/transverse thread 7s" as shown in FIG. 6 .

At the same time, the upper weft thread 7s″ corresponds to a tip of the corresponding force deflection structure 140. Only the warp thread 4k″ (row 4) extends above the upper weft thread 7s″ according to the fabric cross section of FIG. 6 and the weave design according to FIG. 7 .

Warp thread 4k" (row 4) is preferably the only warp thread in the shown warp thread loop, which has a course above the upper weft thread 7s". The course of warp thread 4k" is selected with respect to the adjacent weft threads 6s", 8s" in such a way that it extends below the weft threads 6s", 8s" in contrast to the warp threads 2k". Warp thread 4k" then floats until it reaches the adjacent force deflection structure 40 on the same side of the flat-width woven body, where its course is repeated.

Weft yarns 5s" (row 5) and 9s" (row 9) are positioned adjacent to lower weft yarns 6s", 8s", which form two further lower weft yarns. Thus, in the longitudinal direction, weft yarns 6s", 7s", 8s" (rows 6-8) are positioned between the other two weft yarns 5s", 9s".

The warp yarn 2k" extends under the other lower weft yarns 5s", 9s" according to the fabric cross-section of Figure 6 and the organizational design according to Figure 7. The warp yarn 1k" extends through the other lower weft yarns 5s", 9s" and floats under the weft yarns 6s", 7s", 8s".

The flat-width textile structure 100 additionally has four further lower weft yarns 3s", 4s", 10s", 1s". In the longitudinal direction, weft yarns 4s", 5s", 6s", 7s", 8s", 9s", 10s" are located between further lower weft yarns 3s", 1s", and weft yarns 5s", 6s", 7s", 8s", 9s are located between further lower weft yarns 4s", 10s".

Warp yarn 2k" extends over still further lower weft yarns 4s", 10s" and under still further lower weft yarns 3s", 1s".

The warp yarn 1k" extends through two other lower weft yarns 5s", 9s" according to Figure 6 and Figure 7 and floats between the weft yarns below the weft yarns 6s", 7s", 8s". In addition, the warp yarn 1k" extends below yet other lower weft yarns 4s", 10s" and then floats until the adjacent force deflection structure 140.

The remaining warp threads 3k belonging to the same warp thread loop extend according to FIG. 6 in conjunction with FIG. 7 over yet another lower weft thread 3s″, 1s″ and float between these weft threads under the weft threads 4s″, . . . , 10s″.

The star marked in the rightmost force deflection structure 140 in FIG. 6 has the same meaning as in the first specific embodiment.

The open-width textile structure 10 according to Figure 6 is neither under tension nor under tension, from which it can be seen that the open-width woven body is oriented in such a way due to the interweaving that the points indicating the weft yarns shown in Figure 6 have a preferably zigzag shape in the d-k plane.

If external forces act on the flat-width textile structure 100 in the thickness direction shown (d-axis), the force deflection structures 140 exert their protective effect because they deflect the external forces into the longitudinal direction (k-axis).

When the force deflection structure 140 is stressed, the upper weft yarn 7s" moves toward the two lower weft yarns 6s", 8s", whereby all three weft yarns 6s", 7s", 8s" continue to move toward the floating warp yarn 1k. The floating warp yarn 1k forms a cushion for the three weft yarns 6s", 7s", 8s".

The other lower weft threads 5s″, 9s″ serve as support. If the weft threads 6s″, 7s″, 8s″ are pressed onto the warp threads 1k between the other lower weft threads 5s″, 9s″, the external force is deflected in the longitudinal direction of the open-width woven body 12 .

The warp yarns 3k floating below the weft yarns 4s" to 10s" form another cushion layer for the weft yarns.

The flat-width textile structure 100 can be used as a flat protection as in the first embodiment or can be wrapped to cover, for example, cables. See the corresponding description within the scope of the first embodiment.

The explanations preceding the description of the figures apply correspondingly to the preferred embodiments.
