AI Technical Summary
The glue of traditional light and thin down fabric loses its stickiness after washing it multiple times, causing the down jacket to run away, and the pinholes in the seam will cause leakage of velvet, which cannot effectively prevent velvet drilling.
The fabric edge area and non-fabric edge area are formed by interweaving the fabric edge area, which forms the filling pipe and the filling mouth. The non-fabric edge area is interweaving to form the filling area and the compression joint. Avoid using pressing glue or descensors. The down is directly filled with the filling mouth through the filling mouth. The compression joints formed by the interweaving fix the down to prevent the running and leakage of velvet.
The effect of not running or leaking down is achieved. At the same time, the locking of the velvet is strengthened through the air interface protective film to maintain continuous filling and heat retention.

At this time, the first warp yarn 110 and the first weft yarn 130 are interwoven into a plain weave or a 2 / 2 square weave or a 2 / 2 Twill weave, the second warp yarn 120 and the second weft yarn 140 are interwoven into a plain weave or a 2 / 2 square weave or a 2 / 2 twill weave, preferably, the first warp yarn 110 and the first weft yarn 130 are interwoven into a 2 / 2 twill weave, and the second warp yarn 120 and the second weft yarn 140 are interwoven into a 2 / 2 twill weave. When interweaving, the selvedge area 100 is drawn in by partitioning, and the first warp yarns 110 are all in the surface layer 201, then they are all worn in the front area, and the second warp yarns 120 are all in the inner layer 202 , then they are all worn in the back area, and every 4 warp yarns are inserted into a reed tooth, and this cycle is repeated 21 times, thereby interweaving to form a 2 cm filling pipe 300, and there is a filling port 600 with a width of 2 cm every 3 cm on the filling pipe 300, and the filling port 600 is connected with the first square filling area 401 in the non-seam area 200 in the weft direction, so that the down can be filled into the filling area through multiple filling ports 600, so that each filling area can have down and be full.
[0023] The non-seam area 200 also includes a surface layer 201 and an inner layer 202. In a complete weaving cycle, the 9th to 72nd warp yarns and the 1st to 64th weft yarns are interwoven to form a first square filling area 401, a second square filling area 402, a first square filling area 501 and the square pressing seam 502.

The yarn arrangement of the first weft yarn 130 and the second weft yarn 140 is 1:1. At this time, the first warp yarn 110 and the first weft yarn 130 are interwoven into a plain weave or a 2 / 2 square weave or a 2 / 2 twill weave, and the second warp yarn 120 and the second weft yarn 140 are interwoven into a plain weave or a 2 / 2 square weave or a 2 / 2 twill weave. Preferably, the first warp yarn 110 and the first weft yarn 130 are interwoven into a plain weave, and the second warp yarn 120 and the second weft yarn 140 are interwoven into a plain weave. When interweaving, the non-selvedge area 200 is drawn in by straight threading, and every 2 warp yarns are inserted into a reed tooth.
[0024] Thus, in the non-seam area 200, the first warp yarn 110 and the first weft yarn 130 in the surface layer 201 are interwoven with the second warp yarn 120 and the second weft yarn 140 in the inner layer 202 to form a first square filling area 401. In the oblique direction, at the junction of two adjacent first square filling areas 401, there is a square pressing seam 502 formed by interweaving the second warp yarn 120 and the second weft yarn 140 in the surface layer 201 with the first warp yarn 110 and the first weft yarn 130 in the inner layer 202, and the four sides of the first square filling area 401 extend outwardly to form four second square filling areas. The four second square filling areas 402 are arranged in the middle of the first square filling areas 402, and a third square filling area 501 is formed by interweaving the first warp yarn 110 and the first weft yarn 130 in the surface layer 201 with the second warp yarn 120 and the second weft yarn 140 in the inner layer 202. The first square filling area 401, the second square filling area 402 and the third square filling area 501 are all interwoven with the same layer of yarn and the same organization, so the first square filling area 401 is connected with the second square filling area 402, and in the warp direction, the two second square filling areas 402 are connected with the first square filling area 401 from top to bottom, and in the weft direction, the two second square filling areas 402 are connected with the third square filling area 501. A square filling area 401 is formed to be connected to the left and right, and a third square filling area 501 is interwoven in the center of the four second square filling areas 402, and the third square filling area 501 is connected to the second square filling area 402 in four directions, and two square pressing seams 502 are interwoven at the intersection of two adjacent first square filling areas 401 in the oblique direction, because the first warp yarn 110 and the first weft yarn 130 of the two square pressing seams 502 at this time as the first warp yarn 110 and the first weft yarn 130 of the surface layer 201 are made into the warp and weft yarns of the inner layer 202, and the second warp yarn 120 and the second weft yarn 140 of the inner layer 202 are used as the warp and weft yarns of the surface layer 201, so that the four sides of the two square pressing seams 502 are close to the first square filling area. The four sides of the area 401 are crossed, so that the two square pressed seams 502 are closed, and the first square filling area 401 is not connected in the southeast, northeast, southwest and northwest directions. Therefore, when filling down, the filling pipe 300 passing through the edge area 100 fills the down into the first square filling area 401 through the filling port 600, and then fills the down into the second square filling area 402 through the first square filling area 401, and then fills the down into the third square filling area 501 through the second square filling area 402, while the square pressed seams 502 are not filled, so as to form isolation between the down and reduce the running of the down. The square pressed seams 502 replace the traditional stitches, and the down will not leak out without pinholes.
[0025] The first warp yarn 110 and the first weft yarn 130 of the fabric are made of 15D-75D acrylic fiber, preferably, 40D acrylic fiber, the second warp yarn 120 and the second weft yarn 140 are made of 20D-80D polyester fiber, preferably, 40D polyester fiber, the total warp and weft density of the double layer is 250 strands / inch-400 strands / inch, preferably, the total warp and weft density of the double layer is 322 strands / inch, the warp density is 240 strands / inch, and the weft density is 82 strands / inch. If the yarn count of the double layer is the same, the fabric will not be wrinkled due to uneven tension of the first warp yarn 110, the second warp yarn 120, the first weft yarn 130, and the second weft yarn 140 when they are exchanged and interwoven.
[0026] The fabric width is 144 cm, and the fabric edge area 100 only exists on the left side or the right side of the fabric, in this embodiment, it is the left side, so the filling pipe 300 formed by interweaving the fabric edge area 100 is 2 cm, and the area outside the fabric edge area 100 is the non-fabric edge area 200. Therefore, 142 cm is formed by interweaving the 9th warp yarn to the 72nd warp yarn 270 times, and the total fabric width is 144 cm, which can reduce fabric waste during cutting and reduce fabric costs.
[0027] The interwoven surface of the fabric is treated with double repellency so that the surface layer 201 is covered with a protective film 700 of the air interface, which can not only protect the down from penetrating out of the fabric and strengthen the down locking, but also make the fabric have a triple-proof effect.
[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
