Abstract

According to the present invention, an embossed fabric having a linear protrusion part. The embossed fabric in which a bottom structure is formed by intersection of bottom weft yarn and warp, a protrusion weft at least twice thicker than the bottom weft is spaced at a predetermined interval. In addition, a protrusion structure part is formed in a way that, at the intersection of the protrusion weft and warp, an upper cross in which warp is crossing over two or more protrusion wefts are arranged adjacent to each other and a lower cross that is woven while warp intersects the bottom wefts disposed between the protrusion wefts while passing through the bottom of the protrusion wefts are alternately formed. By a contraction difference between the bottom structure, the protrusion weft and protrusion structure part, the protrusion structure part is more protruded than the bottom structure, thereby forming a dike-shaped protrusion part.

Description

Embossed fabric with dike-shaped protrusion

The present invention relates to a woven fabric having irregularities on its surface, and more particularly, to an uneven fabric of a form in which a protrusion is formed by a protrusion of a thread or tissue on the bottom surface, rather than a surface irregularity caused by wrinkles. .

In the selection of baby goods and elderly goods, in recent years, interest in not only the design but also the functionality of the product, affinity with the human body, affinity with nature, and the like has increased.

Currently, the most common materials for bedding materials satisfying such functionalities have been using stiff and cool materials such as linens to prevent them from sticking to the skin or quilting thin cotton on the inside.

Another method is weaving by rayon, then crease and use it as cold-sensitive material. However, these materials are also high in the price of the material itself, the wrinkles generated in the fabric is not permanent, giving a visual satisfaction to the consumer only at the time of sale, there is a problem that the function is not sufficiently expressed because the wrinkles are weak during the actual use.

As another method, functional processing using a method of coating or encapsulating a cooling material such as xylitol on the fiber surface has been attempted.However, in such a method, the function disappears due to friction and washing during use. There is a problem that it is impossible to provide a period cooling effect.

In order to solve the above problems, the present inventors shrink the multi-layered fabric having three or more layers including an inner layer having a shrinkage rate of 10-50% higher than that of the surface layers through a dyeing or processing process, and the surface layers And a method for producing a bedding fabric having wrinkles formed on the surface, characterized by forming wrinkles on the surface layers due to the difference in shrinkage between the inner layer and the inner layer. 1478176 is disclosed.

As shown in FIG. 3, the acupuncture cloth 100 according to the present invention has an inner layer 102 that contracts more than the surface layers 101 and 103, so that the surface layer 101 and 103 that has less shrinkage has a different area. As the bend is formed, various wrinkles are formed, thereby improving the volume, and the area of contact with the skin is reduced due to the unevenness caused by the bending of the surface layers 101 and 103, and a ventilation path may be formed along the groove of the uneven portion. There was an advantage to feel comfortable when touched.

By the way, the conventional wrinkled fabric including the above invention has a difference in detail, but as shown in FIG. 3, a large area of the surface layer is raised to form a convex portion formed by weaving such as an arch or a dome. do. Therefore, since the area in contact with the skin is formed in a planar shape and the area of contact with the skin is relatively high, there is a limit to improving the comfort feeling when touching the skin due to the limited area where sweat on the skin can evaporate or aeration. have.

In addition, since the shape of the curvature appears in the form of wrinkles in which the surface layer is wrinkled, there is a limitation in that it is difficult to secure the stereotype and cannot form a pattern of the form directly expressed by the surface tissue.

Therefore, in order to obtain a more comfortable and design-excellent product, the linear contact is made at the time of contact with the skin by the vivid linear irregularities directly formed on the surface layer, and the comfort is increased, and the various tissue patterns formed in the linear shape The situation is required to develop a fabric that can implement the details in detail.

The present invention solves the problems of the prior art described above, the volume and thermal insulation and the comfort in contact is improved by the weaving projections close to the line formed directly on the surface layer of the fabric, the uneven fabric is also excellent in design The purpose is to provide.

Uneven fabric according to the present invention for solving the above problems,

The floor tissue is formed by the intersection of the bottom weft and the slope,

Protruding weft yarn thicker than twice the bottom weft yarn is repeatedly arranged at a predetermined interval,

At the intersection of the protrusion weft and the inclination,

An upper intersection crossing over two or more protruding weft yarns inclined adjacent to each other, and a lower crossing interwoven with the bottom wefts disposed between the protruding wefts while inclining through the lower portions of the protruding wefts Alternating protrusions are formed,

By the difference in the contraction rate between the bottom tissue and the protrusion weft and the protrusion tissue portion, the protrusion tissue portion protrudes from the bottom tissue, characterized in that the weave-shaped protrusions are formed, characterized in that the protrusions formed.

Preferably,

The projecting tissue portion is formed in a predetermined width,

Spaced apart between the protruding tissues, a protruding weft exposed portion is formed in which the protruding weft is exposed in a yarn state over the tissue where the bottom weft and the inclined cross are formed;

More preferably,

The protruding tissue portion is formed by alternately pairing with the protruding weft yarns arranged on the upper part and the lower part about the one protruding weft thread and repeatedly formed by a predetermined width.

Also preferably, the uneven fabric is a multi-woven fabric in which two or more fabric layers including two surface layers are joined to each other, wherein the weaving protrusions are symmetrically formed at the same position of the two surface layers. do.

According to the present invention, since the concavo-convex fabric having the shape of the embankment-shaped protrusion formed on the surface of the fabric is realized, it is possible to form a clear and regular pattern, and the protrusion that touches the skin when used for bedding or the like. Since the part is close to the shipboard, there is an advantage of having excellent breathability and a very pleasant touch.

Since the fabric according to the present invention has an excellent volume feeling, it can be used for a bedding or the like requiring a volume feeling without using a separate filler.

In addition, the fabric according to the present invention is not limited to the selection of materials, because irregularities are formed by shrinkage in a general refining or dyeing process, without incorporating a separate special component or special processing process, for example 100% As in the form of cotton fabric, it can be implemented using only pure natural materials, and if necessary, various functional materials can be mixed to express functionality.

Hereinafter, with reference to the accompanying drawings will be described in more detail the concave-convex fabric formed with weir-shaped protrusions according to the present invention.

Figures 1a to 1d is a photograph showing the shape of the uneven fabric according to one embodiment of the present invention, Figure 1a shows the fabric (1 ') before shrinkage showing the state after the tension is removed during weaving 1B and 1C show the front and back sides of the surface layer of the uneven fabric 1 in the contracted state, and FIG. 1D shows the cross section.

Referring to these drawings, as for the uneven fabric 1 according to the present invention, weaving protrusions 20 are projected on the bottom structure 10 formed by the intersection of the weft bottom and the warp yarns, and the weaving protrusions ( 20) to have unevenness.

Here, the bottom weft 11 and the inclined 12 forming the floor tissue 10 is not particularly limited as a conventional thread selected for the purpose of the uneven fabric, the bottom weft 11 and the inclined 12 is The same thing may be used and a different thing may be used. In addition, it is not necessary to form the bottom structure by using one type of the weft bottom 11 or the slope 12, and may be used by combining different kinds of fibers, fineness, color, and the like. (The bottom weft 11 and the inclined 12 forming these bottom tissues 10 constitute not only the bottom tissue but also a part of the weft-shaped protrusion 20 described later.)

In addition, the shape of the tissue constituting the bottom tissue 10 itself is not particularly limited, but in order for the protrusion effect of the weir-shaped protrusion 20 to appear well, flat tissue such as plain weave is preferable.

In the case of bedding and the like, which are most noticed as the use of the uneven fabric of the present invention, the kind of fibers is most preferably cotton, hemp, cellulose fibers such as rayon, and the like, but is not limited thereto. Synthetic fibers such as polyester, nylon, acrylic, and polypropylene can also be used.

The embankment-shaped protrusion 20 is formed by protruding tissue portion 22 including the protruding weft yarn 21 to protrude from the bottom tissue 10 due to a difference in shrinkage rate.

Specifically, the protruding wefts 21 are spaced at predetermined intervals between the bottom wefts 11 using a thread having a fineness two times or more thicker than the bottom wefts 11. The material of the protruding weft yarn 21 is not particularly limited, and it is preferable to use a material suitable for the purpose as in the bottom weft yarn 11.

In the illustrated embodiment, the base weft yarn 11 and the warp yarn 12 are combined with 40 s cotton yarn, and then twisted with 600 TM in the S direction, and the protruding weft yarn 21 is doubled with 10 male cotton yarns. It is shown to have been woven using the yarn with 200TM in the direction.

In this case, the intervals at which the protruding wefts 21 are arranged are such that the bottom wefts 11 are arranged five times and the protruding wefts 21 are arranged once, and the protruding wefts are spaced apart from each other in the tissue in which the bottom wefts are arranged. Are arranged. The spacing between the protruding wefts 21 is usually constant, but it is also possible to design a variety of structures such as repeating irregularly, regularly or radially in a narrow and wide manner.

According to the invention, this protruding weft 21 does not form a tissue by intersecting the warp 12 in the same way as the bottom weft 11 and the warp 12 intersect, but the warp 12 in a special manner. Are interwoven to form a protruding tissue portion 22.

That is, at the portion where the protruding weft yarn 21 and the warp yarn 12 intersect, the top cross 22A crossing the top of two or more protruding weft yarns 21 in which the warp yarns 12 are arranged next to each other, and the inclination Protruding tissue portions are alternately formed so that the lower crosses 22B interweaved while intersecting the bottom wefts 11 disposed between the protruding wefts 21 while passing through the lower portions of the protruding wefts 21 are formed. To form (22).

The ratio of the upper intersection to the lower intersection may be 1: 1 or may be variously designed. However, in the illustrated embodiment, the upper intersection and the lower intersection are arranged in 2: 1 without alternating 1: 1 and thus the intersection point. The less protruding weft yarn 21 is firmly fixed, and at the same time, the protrusion is made more clear.

In addition, in the illustrated embodiment, the protrusion tissue portions 22 are formed to have a predetermined width L without being continuously formed along the protrusion wefts 21, and the protrusion tissue portions 22 are spaced apart from each other by the predetermined intervals D. Thus, between the spaced projecting tissue portion 22, the projecting weft 21 is to form a projecting weft exposed portion 23 exposed in a yarn state of the tissue intersected with the bottom weft yarn inclined. This weft-exposed part 23 can be regarded as actually formed by the lower cross 22B in a predetermined width.

In the protruding weft exposing portion 23, since the protruding weft 21 is exposed as it is for a predetermined width, changing the color of the protruding weft 21 or changing the material can express a unique color or functionality by the protruding weft. have.

In addition, since the protruding weft-exposed part 23 has a high possibility of contact with the skin, the protruding weft-exposed part 23 may adopt various materials suitable for the purpose to improve the functionality. For example, it is possible to obtain a cooling effect by using a yarn made of a material having good thermal conductivity such as HDPE (high density polyethylene). When using rayon material, it is particularly useful in summer because it is effective for absorbing sweat and imparting a feeling of cooling.

In addition, according to the present embodiment, in forming the protruding tissue portion 22, instead of being formed continuously between neighboring protruding weft yarns, the upper part 21B of the protruding weft yarns 21A or the center thereof is formed. It alternates with the protruding wefts arranged in the lower part 21B, and forms it by predetermined width.

As described above, when the protruding tissues are formed such that one protruding weft yarn 21A alternately mates with the protruding weft yarns above and below, the protruding tissue parts of the upper and lower parts of each protruding weft yarn 21A are alternately contracted by contraction. The protruding weft yarn 21A is pulled toward the protruding tissue portion 22, which is contracted, to bend.

In this embodiment, by constructing in this way, the webbing-shaped protrusions 20 repeatedly form irregularities in the form of the honeycomb-shaped weirs surrounding the floor tissue 10.

When weaving is completed in such a form, and shrinkage occurs in a process such as refining or dyeing, a difference in shrinkage degree occurs depending on a part. That is, the portion of the lower intersection where the cross is hard due to the crossing of the warp / weft is low but the density of the yarn is low, the contraction is large, and the bottom tissue 10 having the high density of the yarn having the high density but having the high density maintains moderate contraction. The portion where the weft weft 21 and the upper cross 22A have almost no bending due to the intersection is hardly contracted, and the portion where the protrusion weft exposed portion 23 and the upper cross 22A is formed is the bottom tissue 10. However, it forms a protruding portion in the shape of a weir above the portion of the lower intersection 22B which is highly contracted.

At this time, if the projection weft yarn 21 uses a yarn having a smaller shrinkage rate than the bottom weft yarn 11, it is more advantageous for the formation of the weir-shaped protrusion 20.

Figures 2a to 2b is a schematic diagram showing the action of forming the weft-shaped protrusions by the shrinkage in the uneven fabric according to the present invention, when described further with reference to these drawings, as shown in Figure 2a in the initial weaving state Protruding weft 21 is arranged in the horizontal direction, the state in which the inclined 12 and the upper cross or the lower cross only in the protrusion tissue portion 22. In this state, when the weaving tension is removed and contraction is performed in the contraction process, the projecting tissue portion 22 and the projecting weft yarn are strongly contracted while the projecting tissue portion 22 having high shrinkage is strongly contracted in the direction indicated by the arrow of FIG. 2B. The weft exposed portion 23 exposed 21 is projected onto the bottom tissue to form an uneven fabric in which weir-shaped protrusions are formed.

On the other hand, according to the present embodiment, as shown in Fig. 1D, the uneven fabric 1 is composed of a double-woven fabric woven to have two surface layers 1A and 1B. In addition, although not shown, a multi-woven form in which one or more inner layers are formed between these two surface layers is also possible.

According to the present embodiment, weir-shaped protrusions 20 formed on the front and rear two surface layers 1A and 1B are symmetrically formed at the same position on both surface layers. Therefore, the thickness of the portion in which the two weir-shaped protrusions are formed is much stronger and thicker than the portion in which the two bottom tissues are joined to each other, and the bottom tissue portion exhibits flexibility.

In addition, in the present embodiment, as shown in Figs. 1B and 1C, the colors of the protruding wefts 21 of the two front and rear surface layers 1A and 1B are used differently in red and blue, so that both sides have different colors. Doing.
