[0001] The present application relates to the field of fabric, more particularly, to a warm fabric and its weaving process. BACKGROUND

[0002] The common air layer fabric at present has certain warmth but feels a little stuffy because of using polyester fiber. The filling fabric generally uses the way of quilting to sew two layers of fabric to form a filling cavity, but the filling amount is less at the quilting part and its vicinity, and the quilting is broken due to friction or hooking problem, so that the filling in the filling cavity is uneven. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art, and provides a warm fabric and its weaving process. When the fabric is filled, the quilting is replaced by knitting connection to reduce the phenomenon of quilting breakage, the first area forms bubbles, and the hollow is formed between the upper and lower bubbles. Because the first area is larger than the second area and the connection, when filled, the fabric can be warm enough. The first area is knitted and connected with the second area and the connection around the first area, and the second area forms an air layer. Therefore, the second area can not only increase the fixation of the filling of the first area, but also increase the warmth of the fabric through the air layer formed by the second area. When the fabric is not filled, the bubbles formed by the first area store heat and increase the air permeability of the fabric, and the air layer formed by the second area keeps the fabric warm all the time.

[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a warm fabric, comprising a first area, a second area and a connection, the second area comprising two upper and lower second parts and an air layer, and the two upper and lower second parts being connected through the air layer, the first area comprising two upper and lower first parts and an intermediate part, the first area being a rectangle, the first area comprising two long sides and two short sides, the ends of the two short sides being connected with the connection, and the connection connecting the midpoint of the short side of the first area with the corresponding long side.

[0005] The present application is further provided that the first area is arranged in a cross pattern at a positive 45-degree angle and a negative 45-degree angle, one negative 45-degree angle first area is arranged between two positive 45-degree angle first areas, and one positive 45-degree angle first area is arranged between two negative 45-degree angle first areas.

[0006] The present application is further provided that the first part forms a bubble, the upper first part forms an upward bubble, the lower first part forms a downward bubble, and the intermediate part is hollow.

[0007] The first area and the second area are arranged in a 1:1 ratio, and the width of the first area is equal to the width of the second area.

[0008] The second area is located at the center surrounded by the four first areas, and the second area is a square, and the four sides of the second area are connected to the first areas and the connecting portions.

[0009] The width of the connecting portion is 1mm-2mm.

[0010] The length of the two second areas and the connecting portion is equal to the length of the long side of the first area.

[0011] The fabric is taken as a cycle with 9 courses of loops, the first and eighth courses of loops adopt the first yarn, the second, third, sixth and seventh courses of loops adopt the second yarn, the fourth course of loops adopts the third yarn, and the fifth and ninth courses of loops adopt the fourth yarn.

[0012] The application further discloses a warm-keeping fabric and a weaving process thereof, which comprises the following steps.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The embodiment discloses a warm-keeping fabric, which comprises a first area 10, a second area 11 and a connecting part 12, the first area 10 comprises two first parts 101 and a middle part 102, the first part 101 forms a bubble, the upper first part 101 forms an upward bubble, the lower first part 101 forms a downward bubble, the middle part 102 is hollow, so that when the fabric is filled, the middle part 102 can accommodate the filler, and because the upper first part 101 forms an upward bubble and the lower first part 101 forms a downward bubble, the fabric increases the accommodation space, thereby increasing the warmth-keeping property, and there is a gap between the fillers, and the middle part 102 is hollow, thereby increasing the air permeability of the fabric, when the fabric is not filled, because the middle part 102 is hollow, the hollow structure not only reduces the weight of the fiber, but also increases the warmth-keeping property while the fabric is light, and because the middle part 102 is hollow, the range of the middle part 102 is limited, and the middle part 102 initially stores hot air, when the fabric reaches a certain heat, the human body produces part of the water vapor, at this time, the water vapor produced by the human body and the stored hot air form an air flow with the outside air, but the heat in the middle part 102 is always more than the water vapor and the outside air because of the range limitation, so that the middle part 102 can perform part of the air conversion while storing hot air, thereby increasing the air permeability of the fabric on the basis of the warmth-keeping property.

[0030] The first area 10 is arranged in a positive 45-degree angle and a negative 45-degree angle, the two first areas 10 in the positive 45-degree angle are separated by a first area 10 in the negative 45-degree angle, and the two first areas 10 in the negative 45-degree angle are separated by a first area 10 in the positive 45-degree angle, because the first area 10 is arranged in the positive and negative 45-degree angle, the friction between the first areas 10 is increased, the structure of the first area 10 is relatively stable, and because the positive and negative 45-degree angle is arranged, the two first parts 101 of the first area 10 are not stitched by the quilting, and the stability of the two first parts 101 of the first area 10 is still increased, so that when the fabric is filled, the first area 10 can limit the range of the filler, thereby reducing the phenomenon of uneven filler, increasing the stability of the filler, and increasing the warmth-keeping property of the fabric, because the first area 10 is woven in the positive and negative 45-degree angle instead of the quilting, the phenomenon of unstable filler caused by the breakage of the quilting is reduced, when the fabric is not filled, because the first area 10 is arranged in the positive and negative 45-degree angle, the first area 10 increases more air channels, thereby improving the air permeability of the fabric.

[0031] The second area 11 includes two second parts 111 and an air layer 112, and the two second parts 111 are connected by the air layer 112. When the fabric is filled, because the two second parts 111 of the second area 11 are connected by the air layer 112, the second area 11 is solid, thereby blocking and fixing the filler, keeping the filler in a fixed position, and increasing the warmth retention of the fabric. When the fabric is not filled, because the air layer 112 is in the middle of the two second parts 111, the second area 11 has a three-layer structure, thereby making the fabric have good extensibility and loftiness. Because the middle is the air layer 112, the loftiness and elasticity formed between the yarns form a static air layer 112, thereby increasing the warmth retention of the fabric.

[0032] The first area 10 is rectangular, and includes two long sides and two short sides. The ends of the two short sides are connected with a connecting part 12. The connecting part 12 connects the midpoint of the short side of the first area 10 and the corresponding long side. The width of the connecting part 12 is 1mm-2mm, and preferably 1.2mm. When the fabric is filled, if the width of the connecting part 12 is less than 1mm, because the connecting part 12 is too small to limit the first area 10, the filler in the first area 10 will run, causing uneven filler in the first area 10. If the width of the connecting part 12 is greater than 2mm, because the connecting part 12 is too large, the first area 10 cannot form a rectangle, also causing uneven filler, thereby affecting the warmth retention of the fabric. When the fabric is not filled, if the width of the connecting part 12 is less than 1mm, the first area 10 is not limited and forms a communication, so that the air cannot be static, thereby causing the first area 10 to not form a warm cavity. If the first area 10 is completely connected, the air flow is increased, but at the same time, a large amount of heat generated by the human body is taken away, thereby reducing the warmth retention of the fabric. If the width of the connecting part 12 is greater than 2mm, the range of the first area 10 and the second area 11 will be reduced. Because the fabric is not filled, the second area 11 increases the warmth retention of the fabric through the air layer 112, and the first area 10 stabilizes the warmth retention of the fabric through the middle part 102. Therefore, reducing the range of the first area 10 and the second area 11 will reduce the warmth retention of the fabric.

[0033] The first area 10 and the second area 11 are arranged in 1:1, and the second area 11 is located in the center surrounded by four first areas 10, and the second area 11 is a square, and the four sides of the second area 11 are connected with the first area 10 and the connecting part 12, and the first area 10, the second area 11 and the connecting part 12 are connected, and the first area 10 is a three-layer hollow, the second area 11 is a three-layer solid, and the connecting part 12 is a single layer, so that the first area 10, the second area 11 and the connecting part 12 form an interval and an interlacing, because the arrangement increases the frictional force on the surface of the dispersed fabric, thereby improving the wear resistance of the fabric.

[0034] The fabric is arranged in 9 courses, each course including an upper high butt needle, an upper low butt needle, a lower high butt needle, and a lower low butt needle. The 1st, 4th, and 8th courses are full needle knitting, the 2nd, 3rd, 6th, and 7th courses are under-knitted into loops, and the 5th and 9th courses are not knitted with weft. The 4th-6th courses and the 8th-1st courses form the second area 11, and the 2nd-4th courses and the 6th-8th courses form the first area 10. The first area 10 includes a first part 101 and a middle part 102, and the 1st course knits a connecting part 12 connecting the upper and lower first parts 101 of the first area 10. The full needle knitting of the first area 10 and the second area 11 in the 4th and 8th courses forms the connecting part 12, so that the width of the first area 10 and the second area 11 is equal, and the length of the two second areas 11 and the connecting part 12 is equal to the length of the long side of the first area 10, so that the middle part 102 is hollow, and each side of the first area 10 is limited, so that each area is balanced, increasing the stability of each area. When the fabric is subjected to external force, the first area 10 always remains hollow, increasing the warmth of the fabric when filled, and increasing the air permeability of the fabric when not filled.

[0035] The first yarn 21 is used in the first and eighth loop rows, the second yarn 22 is used in the second, third, sixth and seventh loop rows, the third yarn 23 is used in the fourth loop row, and the fourth yarn 24 is used in the fifth and ninth loop rows. The first yarn 21 is a DTY fiber, the second yarn 22 is a blended yarn of 65% polyester fiber and 35% cotton fiber, the third yarn 23 is an empty package yarn blended with DTY fiber and spandex fiber, and the fourth yarn 24 is a graphene fiber. The first yarn 21 has a yarn count of 75D / 36F, the second yarn 22 has a yarn count of 75D / 36F, the third yarn 23 has a yarn count of 50D / 48F, and the fourth yarn 24 has a yarn count of 75D / 48F. The fabric is knitted with a 34-inch barrel diameter and 28 stitches per inch. At the same density, because the third yarn 23 has a finer yarn count than the other single yarns, the fourth loop row in each region is looser than other places, making the yarns more loose, thereby increasing the warmth of the fabric. Because the yarns are loose, they can capture and release heat, so when the fabric is filled, the first region 10 can increase the air permeability of the fabric. When the first region 10 is not filled, the heat carried away by the air flow in the first region 10 can be supplemented by the heat captured between the yarns, so that the fabric still maintains warmth.

[0036] The fabric is finished with a napping process to increase the warmth of the fabric, and a loose bubble finishing process is used to increase the bubble height of the first part 101 of the first region 10, thereby increasing the filling and heat storage space. The finished fabric has a first region 10 including a middle part 102, and the height of the second region 11 is the same as the height of the middle part 102 of the first region 10, so that the second region 11 can limit the opening of the two ends of the first region 10, thereby forming a closed space in the first region 10, reducing the movement of the filler when the fabric is filled, and increasing the storage of hot air when it is not filled.

[0037] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the scope of the present application should be considered within the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application should also be considered within the protection scope of the present application.
