Description

Technical Field

[0001] The invention relates to the technical field of clothing weaving, and in particular to a down jacket channel cloth and a sewing method thereof. Background Art

[0002] At present, the channel fabrics for down jackets on the market are mainly obtained by quilting, laminating non-woven methods and integrated weaving;

[0003] The processing method of quilted channel cloth is the simplest. Two or more layers of surface cloth or liner cloth are directly quilted together to form a down channel. Its advantage is that the pattern and position of the quilting line can be changed at will according to the design, and the pattern effect is rich, but it is very easy for down to run from the sewing line;

[0004] Lamination is based on quilting, using adhesive glue instead of stitches to directly laminate two or more layers of surface fabric or lining fabric together to form a filling channel. Its disadvantages are poor lamination fastness, easy to open glue, and a certain width must be guaranteed for lamination, which affects the appearance of the finished product;

[0005] One-piece weaving is to design the fabric structure directly in the weaving stage to weave a fabric with channels. Its main advantages are stable anti-down effect and low risk, but its disadvantages are limited by the weaving process and small pattern changes. Among them, the one-piece weaving structure includes two-layer structure and three-layer structure. The weaving of the two-layer structure is relatively simple, but since there is no middle layer, it is impossible to fill the front and back of the channel fabric with down, so its warmth retention is poor.

[0006] The current three-layer structure is generally woven in a way that the upper, middle and lower layers are staggered. Although the channel cloth of this structure can be filled with down on both sides of the channel cloth, it has a good warmth retention effect, but there is a possibility of down leakage at the connection between each two layers.

[0007] In summary, the problem of down oozing out of the channel fabric of the three-layer down jacket in the prior art still needs to be further improved. Summary of the invention

[0008] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a down jacket channel cloth and a sewing method thereof, so as to reduce the possibility of down running out of the three-layer structure down jacket channel cloth. To achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0009] A down jacket channel cloth (first technical solution), comprising an upper fabric, a middle fabric and a lower fabric, wherein the upper fabric, the middle fabric and the lower fabric are spaced at a certain distance to form a common interweaving point; M first channels and N (N≠M) second channels are arranged between two adjacent common interweaving points; the first channel is located between the upper fabric and the middle fabric; the second channel is located between the middle fabric and the lower fabric; the width of the first channel is greater than the width of the second channel.

[0010] Based on the first technical solution, a second technical solution is also provided. In the second technical solution, one weft loop of the channel cloth includes 10 warp yarns in the warp direction and six regions in the weft direction; each region in the weft direction includes n weft loops, and one weft loop includes 6 weft yarns; the weft insertion position of the channel cloth is as shown in the attached manual. Figure 1 As shown; the organization diagram of channel cloth weaving is as attached to the instruction manual Figure 2 shown.

[0011] Based on the second technical solution, a third technical solution is also provided. In the third technical solution, the warp yarns and weft yarns used in the upper fabric, the middle fabric and the lower fabric are made of polyester 50 / 72SD.

[0012] A method for sewing a down jacket channel cloth based on the second or third technical solution, wherein the weaving of the down jacket channel cloth is carried out through the changes of the six regions as described in the second technical solution, and the minimum tissue cycle is completed, and the weaving is completed by repeating this cycle; the starting point and the end point of the minimum tissue cycle are both the common interweaving points described in the first technical solution; wherein the specific weaving steps of the down jacket channel cloth are as follows:

[0013] Step 1: Arrange the warp threads of the upper fabric, middle fabric and lower fabric according to the instructions. Figure 1 Drawing in the heddle is performed according to the drawing in schematic diagram shown;

[0014] Step 2: The warp threads of the upper fabric, the middle fabric and the lower fabric are completely connected together by interweaving to form a common interweaving point;

[0015] Step 3: Starting from the common interweaving point, interweave the common interweaving warp and weft to form a single-layer plain weave;

[0016] Step 4: interweave the warp yarns of the upper fabric, the middle fabric and the lower fabric in pairs, so as to form M first channels and N (N≠M) second channels between two adjacent common interweaving locations, thereby completing the minimum weave cycle;

[0017] Step 5: Repeat steps 2 to 4 n times to complete the weaving.

[0018] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The first technical solution forms common interlacing places at regular intervals between the upper fabric, the middle fabric and the lower fabric, so that the channel cloth will not leak down at the common interlacing places, and sets M first channels between the upper fabric and the middle fabric and N (N≠M) second channels between the middle fabric and the lower fabric between two adjacent common interlacing places, and sets the width of the first channel to be smaller than the width of the second channel, thereby reducing the number of places where the channel cloth leaks down; the principle for achieving the above effect is as follows: the reason why the three-layer structure channel cloth can be filled with down on both the front and back sides is that the channels on the front and back sides are cross-spaced. The channels on the front and back sides of the channel cloth are cross-spaced and have the same width. Therefore, in the prior art, there are basically the same number of down leaking places at the connection between every two layers on the front and back sides of the channel cloth. In the present solution, the channels on the front and back sides are arranged between two adjacent common interweaving places. Since the width of the first channel is greater than that of the second channel, the number of down leaking places on the side where the first channel is located is less than the number of down leaking places on the side where the second channel is located. Moreover, since the common interweaving place is three layers of fabric connected as one, the common interweaving place will not contact the down, and there will be no down leakage. In this way, the possibility of down running through the channel cloth of the three-layer down jacket is greatly reduced.

[0020] Since the upper fabric, middle fabric and lower fabric at the common interweaving are connected as a whole, the front and back sides of the down jacket channel cloth are not in contact with the down; since the widths of the first channel and the second channel are inconsistent and the interweaving method is located between two adjacent common interweaving points,

[0021] 2. The second technical solution provides a specific weaving structure of a tissue loop of the channel cloth to achieve the effect of reducing the leakage of the channel cloth described in the first technical solution.

[0022] 3. The third technical solution provides the materials of the warp and weft yarns used in the upper fabric, the middle fabric and the lower fabric to further achieve the effect of reducing the leakage of the channel cloth described in the first technical solution and the second technical solution.

[0023] 4. The fourth technical scheme provides a specific sewing method for a down jacket channel cloth, so as to weave the down jacket channel cloth described in the second to third technical schemes; in this technical scheme, the common interweaving is achieved by interweaving the upper fabric, the middle fabric and the lower fabric together so that the upper fabric, the middle fabric and the lower fabric are connected as a whole, so as to achieve the effect that there will be no down leakage at the common interweaving; the first channel and the second channel are formed by starting from the first common interweaving to form a single-layer plain weave, and then separately weaving three layers of fabric to form a channel, and after changes in 6 areas, completing the minimum cycle, and repeating the cycle, thereby greatly reducing the possibility of down leakage on the front and back sides of the three-layer channel cloth.
