Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be further described below with reference to the specific drawings.

Many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can do so without departing from the connotation of the present invention. Similar promotions are made, so the present invention is not limited by the specific embodiments disclosed below.

Please refer to Fig. 1-1 and Fig. 1-2 for the schematic diagram of the conventional cubic box-shaped fabric structure. In order to study the principle of cube forming, the cube box-shaped fabric is unfolded into Fig. 1-2 by using the reverse thinking method. The box body belongs to the front and rear pieces. The conventional cylindrical weave structure of equal width and height, the box bottom A'B'C'D' is connected to the cylinder ABCD one by one, that is, A'D' is connected to the left AD of the back piece, and B'C' is connected to the right side of the front piece. BC is connected, A'B' is connected with AB on the left side of the front piece, and DC is connected with D'C' in the forward weave. Except DC and D'C' can be connected in the same direction, the other three connections cannot be realized in actual weaving. For example, the connection between A'D' and AD and the connection between B'C' and BC belong to the connection between the horizontal coil and the vertical coil. After the vertical coils A'D' and B'C' have been woven, they have been pulled into the roll by the roller. The cloth device cannot go back in time to sew with AD and BC'; and A and A', B and B' are not on the same vertical line of the woven area, so they cannot be connected.

After the above analysis, it is impossible to weave directly according to the unfolded diagram in Figure 1-2. It must be transformed and deformed. On the premise of conforming to the weaving principle, it is necessary to ensure that the basic parameters of the cube's length, width and height remain unchanged. Combined with the instability of the quadrilateral, the bottom surface A' B'C'D' is converted into a parallelogram, as shown in Figure 2, the schematic diagram of the unfolded structure of the cubic box-shaped fabric after the transformation. The length of the four sides remains unchanged during the conversion process. After the conversion, A and A', B and B' are woven. On the same vertical line of the region, D and D', C and C' are in the same position, so AB and A'B', AD and A'D', BD and B'C', CD and C'D' can all be Smooth connection. After the weaving is completed, the lower woven fabric is stretched. Since the knitted loop is soft and easy to deform, after ironing in the later stage, the bottom surface of the parallelogram can be easily converted into a rectangular bottom surface again, thus forming a cubic structure.

In order to further illustrate the converted weaving method, the weaving process of the fully formed cube box fabric of the present invention includes the following steps:

(1) Transform the cubic box-shaped fabric into Fig. 2, including the bottom surface A'B'C'D' of the parallelogram, the top cover E'F'G'H' of the parallelogram, and the box as the cubic box-shaped fabric The body part, wherein the box body part includes a cylindrical shape formed by ABCGFE facing the outside and ADCGHE facing away from the outside;

(2) Knitting on the four-needle bed, knitting the bottom surface A'B'C'D' of the parallelogram, the top surface E'F'G'H' of the parallelogram and the direction of the box body of the cube-shaped box fabric on the rear needle bed The outer surface ABCGFE (hereinafter referred to as "box body front piece"), the box body back to the outer surface ADCGHE (hereinafter referred to as "box body rear piece") on the front needle bed for knitting the cube box-shaped fabric;

(3) As shown in Figure 3, wherein 1～n are the weaving schematic diagrams of the bottom surface A'B'C'D' of the parallelogram and the top cover E'F'G'H' of the parallelogram; specifically:

Step 3a, after the knitting starts normally, the knitting of the front loop is suspended;

Step 3b, the rear needle bed knits the bottom surface A'B'C'D' from bottom to top as shown in Figure 2. In this embodiment, the length a of the long side A'B' of the bottom surface is shown in Figure 3 In (1), the stitch length from the 23rd knitting needle to the 12th knitting needle area is determined for knitting, and there are 12 stitches in total; as shown in Figure 3(2), every 2 rows of knitting stitches move 1 needle to the right, and the bottom surface moves at the same time A stitch is hung on the left edge of the box body for connecting with the edge loop of AD on the back piece of the box body, and a stitch is hung on the front needle bed corresponding to the right edge of the bottom surface for connecting with the loop on the BC edge of the front piece of the box body;

Step 3c, repeat the above-mentioned step 3b, until the coil weaving length at the bottom surface C', D' reaches the required length b of the short side of the bottom surface, that is, the weaving starting point at the bottom of the box body;

(4) After the bottom surface A'B'C'D' is knitted, conventional tubular fabric knitting is performed on the front and back of the box body on the front needle bed and the rear needle bed respectively; wherein, the EH edge loops of the box body and the back piece are connected to the top and bottom. The loop on the edge E'H' of the cover is connected, and a needle is hung on the back needle bed corresponding to the edge of the front piece FG of the box body for connecting with the loop on the edge of the top cover F'G';

(5) After the knitting of the box body part, the rear needle bed knits the top cover E'F'G'H', and the connection between the top cover E'F'G'H' and the box body part and the bottom surface are in the horizontal direction Symmetrical, that is, the inclined direction of the converted parallelogram is opposite to the bottom surface; when knitting, refer to the knitting method of step 3, and move the whole stitch to the left for every 2 rows of knitting to complete the knitting of the top cover; the front and rear of the top cover and the box body After the left and right edges of the piece are connected, the upper edge of the top cover and the front piece of the box body are closed and sewed using a shoulder narrowing model.

In order to ensure the wear resistance of the bottom surface, yarns with higher twist can be used on the bottom surface of the raw material, and double-sided structure or sandwich structure can be used for the organizational structure to increase the thickness and durability of the fabric. In order to ensure that the four pieces are independent of each other, four yarn feeders are required to weave four areas respectively.

The connection between the top surface and the side edge of the cylinder can be regarded as the connection model of the T-sleeve and the body. When the top surface is knitted, the horizontal loops on the side edge of the cylinder are connected to the longitudinal loops on the top surface one by one according to a certain weaving ratio. After the top front and back pieces are connected with the side edges, the front and back pieces are closed and sutured using the shoulder narrowing model.
