AI Technical Summary
Existing down fabrics suffer from excessively large needle holes due to high-speed friction between the sewing needle and the fabric, making it easy for down to escape through the needle holes, and they also lack breathability and warmth.
The warp and weft yarns interweave to form horizontal and vertical ridges, which, combined with the base fabric area on the front, create multiple small down-filling areas on the fabric surface. On the reverse side, they form a concave-convex structure that restricts down movement and increases breathability and warmth.
It effectively prevents down from escaping through fabric gaps, increases the fabric's breathability and warmth, and makes the down distribution more even.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] As shown in figure Figure 1 The embodiment discloses a down fabric, which comprises a front and a back. The front comprises a front base cloth area 101 and a first area 200. The first area 200 comprises a first transverse raised area 201 and a first longitudinal raised area 202. The back comprises a back base cloth area 102 and a second area 210. The second area 210 comprises a second transverse area 211 and a second longitudinal area 212. Refer to Figure 5, the 4th-6th, 10th-12th, 16th-18th, 22nd-24th warp yarns and the 1st-24th weft yarns are interwoven as plain weave, the 7th-8th, 13th-15th, 19th-21st warp yarns and the 1st-24th weft yarns are not interwoven, and the warp long floats are on the weft yarns, in the interweaving range of the 28th-48th warp yarns and the 29th-52nd weft yarns, the 28th-30th, 34th-36th, 40th-42nd, 46th-48th warp yarns and the 29th-52nd weft yarns are interwoven as plain weave, the 31st-33rd, 37th-39th, 43rd-45th warp yarns and the 29th-52nd weft yarns are not interwoven, and the warp long floats are on the weft yarns, because in the interweaving range of the 4th-24th warp yarns and the 1st-24th weft yarns and in the interweaving range of the 28th-48th warp yarns and the 29th-52nd weft yarns, every three warp yarns are interwoven as plain weave and then every three warp yarns are not interwoven in the width direction of the fabric, therefore when the fabric is taken off the loom, the interwoven part is tight in density, and the not interwoven part is raised, and because of the traction between the warp yarns and the weft yarns, the front of the fabric is raised, and the back of the fabric is formed as a concave-convex structure, therefore the interweaving of the 4th-24th warp yarns and the 1st-24th weft yarns forms a first longitudinal raised area 202 and a second longitudinal area 212, and the interweaving of the 28th-48th warp yarns and the 29th-52nd weft yarns forms a first longitudinal raised area 202 and a second longitudinal area 212, and the first longitudinal raised area 202 is on the front of the fabric, and the second longitudinal area 212 is on the back of the fabric.
[0023] In the interweaving range of the 4th-24th warp yarns and the 29th-48th weft yarns, the 4th-24th warp yarns and the 29th-32nd, 37th-40th, 45th-48th weft yarns are interwoven as plain weave, the 4th-24th warp yarns and the 33rd-36th, 41st-44th weft yarns are not interwoven, and the weft long floats are on the warp yarns, in the interweaving range of the 28th-48th warp yarns and the 5th-24th weft yarns, the 28th-48th warp yarns and the 5th-8th, 13th-16th, 21st-24th weft yarns are interwoven as plain weave, the 28th-48th warp yarns and the 9th-12th, 17th-20th weft yarns are not interwoven, and the weft long floats are on the warp yarns, because in the interweaving range of the 4th-24th warp yarns and the 29th-48th weft yarns and in the interweaving range of the 28th-48th warp yarns and the 5th-24th weft yarns, every four weft yarns are interwoven as plain weave and then every four weft yarns are not interwoven in the length direction of the fabric, therefore when the fabric is taken off the loom, the interwoven part is tight in density, and the not interwoven part is raised, and because of the traction between the warp yarns and the weft yarns, the front of the fabric is raised, and the back of the fabric is formed as a concave-convex structure, therefore the interweaving of the 4th-24th warp yarns and the 29th-48th weft yarns forms a first longitudinal raised area 202 and a second longitudinal area 212, and the interweaving of the 28th-48th warp yarns and the 5th-24th weft yarns forms a first longitudinal raised area 202 and a second longitudinal area 212, and the first longitudinal raised area 202 is on the front of the fabric, and the second longitudinal area 212 is on the back of the fabric.
[0024] Because the first 3 warp yarns, the 25th-27th warp yarns and the first 4, 25th-28th, 49th-52nd weft yarns are interwoven into a plain weave, the first 3 warp yarns, the 25th-27th warp yarns and the 5th-8th, 13th-16th, 21st-24th, 29th-32nd, 37th-40th, 45th-48th weft yarns are not interwoven, and the warp float is on the weft, the first 3 warp yarns, the 25th-27th warp yarns and the 9th-12th, 17th-20th, 33rd-36th, 41st-44th weft yarns are not interwoven, and the weft float is on the warp, and as above, in the interweaving range of the first 3 warp yarns, the 25th-27th warp yarns and the first 52nd weft yarns, after the fabric is taken off the loom, due to the traction between the warp and weft yarns, the plain weave interweaving forms a front base fabric area 101, and the non-interweaving forms a back base fabric area 102, because the front base fabric area 101 and the back base fabric area 102 are interwoven by the same warp yarns, the front of the fabric and the back of the fabric are connected by the front base fabric area 101 and the back base fabric area 102.
[0025] Because the first transverse raised area 201 and the first longitudinal raised area 202 on the front of the fabric are both raised, and the first transverse raised area 201 and the first longitudinal raised area 202 are surrounded by the organization of the front base fabric area 101, the first transverse raised area 201 and the first longitudinal raised area 202 are both connected with the front base fabric area 101, and because the first transverse raised area 201 and the second transverse area 211 are interwoven at the same time, the first longitudinal raised area 202 and the second longitudinal area 212 are interwoven at the same time, and the front of the fabric and the back of the fabric are connected by the front base fabric area 101 and the back base fabric area 102, so that the first transverse raised area 201 and the second transverse area 211 form a down-filled area, the first longitudinal raised area 202 and the second longitudinal area 212 form a down-filled area, and are divided by the front base fabric area 101 and the back base fabric area 102, so that the front of the fabric forms multiple small down-filled areas, because each first transverse raised area 201 and second transverse area 211 form a down-filled area, and each first longitudinal raised area 202 and second longitudinal area 212 form a down-filled area, which forms an independent space, so that the movement of the down can be effectively limited, and because the front base fabric area 101 and the back base fabric area 102 are divided, instead of the sewing process of the fabric, the down can be prevented from escaping from the gap of the fabric.
[0026] Because the first transverse raised area 201 has an organization range of 21 warp yarns and 20 weft yarns, and the first longitudinal raised area 202 also has an organization range of 21 warp yarns and 20 weft yarns, the width of the first transverse raised area 201 is equal to the width of the first longitudinal raised area 202, the length of the first transverse raised area 201 is equal to the length of the first longitudinal raised area 202, and the first transverse raised area 201 and the first longitudinal raised area 202 are located on the back of the fabric, the second transverse area 211 and the second longitudinal area 212 are connected through the back base fabric area 102, so that the down in the plurality of small down-filled areas formed by the first transverse raised area 201 and the first longitudinal raised area 202 can be more evenly distributed inside the fabric, and the first transverse raised area 201 and the first longitudinal raised area 202 are spaced apart, so that the small down-filled areas formed by the first transverse raised area 201 and the first longitudinal raised area 202 are evenly distributed, so that the fabric can more comprehensively increase the overall warmth.
[0027] Because the second transverse area 211 has an organization range of 21 warp yarns and 20 weft yarns, and the second longitudinal area 212 also has an organization range of 21 warp yarns and 20 weft yarns, the width of the second transverse area 211 is equal to the width of the second longitudinal area 212, the length of the second transverse area 211 is equal to the length of the second longitudinal area 212, and the second transverse area 211 and the second longitudinal area 212 are located on the back of the fabric, and the second transverse area 211 and the second longitudinal area 212 are spaced apart, and because in the organization range of each second transverse area 211, every four weft yarns are interwoven and then every four weft yarns are not interwoven, when the fabric is taken off the machine, the interwoven part will be pressed due to the density, so that the non-interwoven part forms a protrusion, and because of the traction between the warp and weft yarns, a protrusion is formed on the front of the fabric, and a concave-convex structure is formed on the back of the fabric, so that after the first transverse raised area 201 is formed on the front of the fabric, the second transverse area 211 is formed on the back of the fabric, and each second transverse area 211 includes three first grooves 2110 and two first protrusions 2111, and the first grooves 2110 and the first protrusions 2111 are spaced apart, and for the same reason, because in the organization range of each second longitudinal area 212, every three warp yarns are interwoven and then every three warp yarns are not interwoven, when the fabric is taken off the machine, the interwoven part will be pressed due to the density, so that the non-interwoven part forms a protrusion, and because of the traction between the warp and weft yarns, a protrusion is formed on the front of the fabric, and a concave-convex structure is formed on the back of the fabric, so that after the first longitudinal raised area 202 is formed on the front of the fabric, the second longitudinal area 212 is formed on the back of the fabric, and each second longitudinal area 212 includes four second grooves 2120 and three second protrusions 2121, and the second grooves 2120 and the second protrusions 2121 are spaced apart, so that when the first transverse raised area 201 and the second transverse area 211 form a down-filled area, the first longitudinal raised area 202 and the second longitudinal area 212 form a down-filled area, because the second transverse area 211 and the second longitudinal area 212 have a concave-convex structure, referring to Figure 3, the concave structure of the second transverse area 211 and the second longitudinal area 212 can increase the internal space of the down filling area, so that the down can be more fluffy, and the air circulation between the fluffy down can be increased, thereby increasing the warmth retention and the air permeability, and the convex structure of the second transverse area 211 and the second longitudinal area 212 can increase the effect of fixing the down, instead of the traditional sewing process, so as to reduce the phenomenon that the down is less distributed at the sewing part, thereby making the down more evenly distributed and increasing the warmth retention of the fabric.
[0028] Because the first groove 2110 and the first convex strip 2111 in the second transverse area 211 are all interwoven by 20 warp yarns and 4 weft yarns, and the second groove 2120 and the second convex strip 2121 in the second longitudinal area 212 are all interwoven by 3 warp yarns and 21 weft yarns, the width M of the first groove 2110 is greater than the width L of the second groove 2120, and the width N of the first convex strip 2111 is greater than the width P of the second convex strip 2121, but because the total number of warp yarns and weft yarns of the second transverse area 211 and the second longitudinal area 212 is the same, the number of concave-convex structures of the second longitudinal area 212 is more than that of the second transverse area 211, so that the stretchability of the second longitudinal area 212 is higher than that of the second transverse area, thereby increasing the elasticity of the fabric and increasing the practicability of the fabric.
[0029] The preferred embodiments of the present application are described above, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
