Description

Technical Field

[0001] The invention relates to the field of fabrics, and more specifically, to a warm-keeping fabric and a weaving process thereof. Background Art

[0002] Currently common air layer fabrics are made of polyester fibers, which have a certain degree of warmth retention but are a bit stuffy. Filling fabrics are generally quilted, with two layers of fabric sewn together to form a filling cavity. However, the filling amount is less at and near the quilted area, and the quilting may break due to friction or snagging, making the filling in the filling cavity uneven. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a thermal insulation fabric and its weaving process. When the fabric is filled, quilting is replaced by weaving connection to reduce the phenomenon of quilting breakage, and bubbles are formed in the first area, and hollows are formed between the upper and lower bubbles. Because the first area is larger than the second area and the connection, the fabric can be sufficiently warm when filled, and the second area and the connection are woven around the first area to form an air layer in the second area. Therefore, the second area can not only increase the fixation of the filling in the first area, thereby increasing the warmth of the fabric through the air layer formed in the second area, but also when the fabric is not filled, the bubbles formed in the first area store heat and the bubbles increase the air permeability of the fabric, and the air layer formed in the second area keeps the fabric warm at all times.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a thermal insulation fabric, including a first area, a second area and a connection, the second area includes two upper and lower second parts and an air layer, and the upper and lower second parts are connected by the air layer, the first area includes two upper and lower first parts and a middle part, the first area is a rectangle, the first area includes two long sides and two short sides, the ends of the two short sides are connected to the connection, and the connection connects the short sides of the first area with the midpoints of their corresponding long sides.

[0006] The present invention is further configured such that the first portion forms bubbles, and the first portion located at the top forms bubbles upwards, and the first portion located at the bottom forms bubbles downwards, and the middle portion is hollow.

[0007] The present invention is further configured such that the first area and the second area are arranged in a 1:1 ratio, and the widths of the first area and the second area are equal.

[0008] The present invention is further configured such that the second area is located at the center surrounded by four first areas, and the second area is a square, and four sides of the second area are connected to the first areas and the connection points.

[0010] The present invention is further configured such that the lengths of two of the second regions and one connection point are equal to the length of the long side of the first region.

[0011] The present invention is further configured such that the fabric has 9 coil rows as one cycle, the 1st and 8th coil rows use the first yarn, the 2nd, 3rd, 6th and 7th coil rows use the second yarn, the 4th coil row uses the third yarn, and the 5th and 9th coil rows use the fourth yarn.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present embodiment discloses a thermal insulation fabric, comprising a first area 10, a second area 11 and a connection 12. The first area 10 comprises two upper and lower first parts 101 and a middle part 102. The first parts 101 form bubbles, and the upper first part 101 forms bubbles upwards, and the lower first part 101 forms bubbles downwards. The middle part 102 is hollow. Therefore, when the fabric is filled, the middle part 102 can accommodate fillers. Moreover, because the upper first part 101 forms bubbles upwards, and the lower first part 101 forms bubbles downwards, the fabric has more accommodating space, thereby increasing the warmth retention of the fabric. Moreover, there are gaps 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 portion 102 is hollow, the hollow structure not only reduces the weight of the fiber, but also because it can contain a large amount of still air, thereby increasing the warmth retention of the fabric while being light. Also because the middle portion 102 is hollow, but the range of the middle portion 102 is limited, and the middle portion 102 is initially used to store heat. When the fabric reaches a certain heat, the human body will produce some water vapor. At this time, the water vapor produced by the human body and the stored heat form an air flow with the outside air. However, the heat in the middle portion 102 is always greater than the water vapor and the outside air due to the range limitation. Therefore, while storing heat, the middle portion 102 can perform partial air conversion, thereby increasing the breathability of the fabric on the basis of warmth retention.

[0030] The first regions 10 are arranged crosswise at positive 45-degree angles and reverse 45-degree angles. A first region 10 at a reverse 45-degree angle is spaced between two first regions 10 at positive 45-degree angles, and a first region 10 at a positive 45-degree angle is spaced between two first regions 10 at reverse 45-degree angles. Because the first regions 10 are arranged crosswise at positive and reverse 45-degree angles, friction between the first regions 10 is increased, making the structure of the first regions 10 relatively stable. In addition, because of the positive and reverse staggered arrangement, the upper and lower first parts 101 of the first region 10 are not quilted. The stability of the two parts 101 of the first area 10 is still increased, so when the fabric is filled, the first area 10 can limit the range of the filling, thereby reducing the uneven filling phenomenon, increasing the fixation of the filling, and increasing the warmth retention of the fabric. Because the first area 10 is woven at 45 degrees forward and backward instead of quilting, the phenomenon of unstable filling caused by quilting breakage is reduced. When the fabric is not filled, because the first area 10 is cross-arranged at 45 degrees forward and backward, more air channels are added to the first area 10, thereby improving the breathability of the fabric.

[0031] The second region 11 includes two upper and lower second parts 111 and an air layer 112, and the upper and lower second parts 111 are connected by the air layer 112. When the fabric is filled, because the two second parts 111 of the second region 11 are connected by the air layer 112, the second region 11 is solid, thereby blocking and fixing the filler, so that the filler always remains in a fixed position, thereby 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 region 11 is a three-layer structure, thereby making the fabric have good ductility and fluffiness, and because there is an air layer 112 in the middle, a static air layer 112 is formed through the fluffiness and elasticity formed between the yarns, thereby increasing the warmth retention of the fabric.

[0032] The first area 10 is a rectangle, and the first area 10 includes two long sides and two short sides. The ends of the two short sides are connected with a connection 12, and the connection 12 connects the short sides of the first area 10 with the midpoints of the corresponding long sides. The width of the connection 12 is 1mm-2mm. Preferably, the width of the connection 12 is 1.2mm. When the fabric is filled, if the width of the connection 12 is less than 1mm, the first area 10 cannot be restricted because the connection 12 is too small, so that the filler in the first area 10 will run away, resulting in uneven filling in the first area 10. If the width of the connection 12 is greater than 2mm, the first area 10 cannot form a rectangle because the connection 12 is too large, which also causes uneven filling, thereby affecting the fabric. Warmth retention: when the fabric is not filled, if the width of the connection 12 is less than 1 mm, the first area 10 is connected because there is no restriction, so the air cannot be still, resulting in the first area 10 being unable to form a warm-keeping cavity. If all the first areas 10 are connected, the air circulation is increased, but at the same time a large amount of heat generated by the human body will be taken away, thereby reducing the warmth retention of the fabric. If the width of the connection 12 is greater than 2 mm, the range between 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 between 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 a 1:1 ratio, and the second area 11 is located at 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 to the first area 10 and the connection 12, and the first area 10, the second area 11 and the connection 12 are all connected, and the first area 10 is a three-layer with a hollow middle, the second area 11 is a solid three-layer, and the connection 12 is a single layer, so the first area 10, the second area 11, and the connection 12 are spaced and staggered, because the arrangement method increases the friction on the surface of the dispersed fabric, thereby improving the wear resistance of the fabric.

[0034] The fabric is composed of 9 rows of coils as a cycle, each row of coils includes an upper high heel needle, an upper low heel needle, a lower high heel needle, and a lower low heel needle. The 1st, 4th, and 8th rows of coils are knitted with full needles, the 2nd, 3rd, 6th, and 7th rows of coils are knitted with lower needles, the 5th and 9th rows of coils are not knitted with weft insertion, the 4th to 6th rows of coils and the 8th to 1st rows of coils are knitted to form a second area 11, the 2nd to 4th rows of coils and the 6th to 8th rows of coils are knitted to form a first area 10, the first area 10 includes a first part 101 and a middle part 102, and the connection 12 formed by the knitting of the 1st row of coils connects the first area 10 The upper and lower first parts 101, the first area 10 and the second area 11 have the 4th and 8th rows of full-stitch knitting as the connecting part 12, so that the widths of the first area 10 and the second area 11 are equal, the lengths of the two second areas 11 and the connecting part 12 are equal to the length of the long side of the first area 10, so that each side of the first area 10, which is hollow in the middle part 102, is restricted, so that each area is checked and balanced, and the stability of each area is increased, so that when the fabric is subjected to external force, the first area 10 always remains hollow, so that the warmth retention of the fabric is increased when it is filled, and the breathability of the fabric is increased when it is not filled.

[0035] The first and eighth rows of coils use the first yarn 21, the second, third, sixth and seventh rows of coils use the second yarn 22, the fourth row of coils use the third yarn 23, and the fifth and ninth rows of coils use the fourth yarn 24. The first yarn 21 is 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 covered yarn blended with DTY fiber and spandex fiber, and the fourth yarn 24 is 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, with a 34-inch tube diameter, is woven at 28 needles / inch. Under the same density, because the yarn count of the third yarn 23 is thinner than that of other single yarns, the 4th row of coils in each area is fluffier than other places, so the yarns are also fluffier, thereby increasing the warmth retention of the fabric. Moreover, because the fluffiness between the yarns can capture and release heat, when the fabric is filled, the first area 10 is used as filling, which can increase the air permeability of the fabric. When the first area 10 is not used as filling, the heat carried away by the air circulation in the first area 10 can be supplemented by the heat captured between the yarns, so that the fabric still maintains warmth retention.

[0036] The fabric is subjected to sanding finishing to increase the warmth retention of the fabric, and the height of the bubbles formed in the first part 101 of the first area 10 is increased through loose bubble finishing, thereby increasing the filling and heat storage space, and the first area 10 of the finished fabric includes a middle part 102, and the height of the second area 11 is the height of the middle part 102 of the first area 10, so that the second area 11 can limit the openings at both ends of the first area 10, so that the first area 10 forms a closed space, which reduces the movement of the filler when the fabric is filled, and increases the storage of heat when it is not filled.

[0037] The above is only a preferred embodiment of the present invention, and 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.
