Description

Technical Field

[0001] The utility model relates to the technical field of denim fabrics, in particular to a denim fabric that can be flexibly matched in color. Background Art

[0002] Existing denim fabrics with colored wefts are all made by sizing and dyeing the warp yarns with indigo or sulfur dyes, and the weft yarns with pre-dyed colored yarns. Therefore, if you want a different colored weft yarn, you have to dye the weft yarns differently before weaving. Similarly, existing colored denim fabrics (with colored warp yarns) also require the warp yarns to be first dyed with a dyeing process before weaving. This results in a long yarn dyeing and weaving cycle, taking at least two weeks to a month. Moreover, if the selected color is not liked by the customer, the finished fabric will be stagnant, which fails to meet customer needs and cannot meet the demand for fast-return products. Therefore, there is room for improvement.

[0003] Therefore, it is necessary to design a denim fabric that can be flexibly matched in color and can solve the above problems. Utility Model Content

[0012] Figure 1 This is a schematic diagram of the organizational structure of the present utility model.

[0013] Figure 2 This is a schematic diagram of dyeing cotton with hydroxyl cationization of cellulose fiber of the present invention.

[0014] The reference numerals in the figures are: warp yarn 001, weft yarn 002. DETAILED DESCRIPTION

[0015] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0016] The applicant's research found that the existing denim colored weft fabrics and colored cow (warp colored) denim fabrics are usually made by dyeing the weft or warp yarns into colors first and then weaving them. Therefore, the dyeing and weaving cycle is long, and it takes at least half a month to a month. Moreover, if the customer does not like the selected color of the woven fabric, it will stagnate, which cannot meet the needs of customers, let alone the rhythm of fast return products.

[0017] To this end, the utility model provides a denim fabric with flexible color matching, which is formed by the sinking and floating interweaving of warp yarn 001 and weft yarn 002, wherein either the warp yarn 001 or the weft yarn 002 is made of pure cotton yarn or one of the yarns blended with regenerated cellulose, when the warp yarn 001 is made of pure cotton yarn or one of the yarns blended with regenerated cellulose, the warp yarn 001 is slurry-dyed into indigo or sulfur color, and the weft yarn 002 is made of hydroxyl cationic cotton spun from cellulose fiber. When the weft yarn 002 is made of pure cotton yarn or a blend of cotton and regenerated cellulose, the weft yarn 002 is not dyed, and the warp yarn 001 is made of yarn spun from hydroxyl-cationized cotton of the cellulose fiber, the first core-spun yarn or the second core-spun yarn. Specifically, the hydroxyl-cationized cotton of the cellulose fiber is a non-elastic yarn spun from hydroxyl-cationized cotton of 100% cellulose fiber. Please refer to Figure 2, the original cotton fiber is negative ion, and the reactive dye is also negative ion, like repels like, through the existing process to change the dye and fiber binding mode, from covalent bond to ionic bond, can achieve salt-free and alkali-free dyeing, the dyeing rate can reach 90%-98%; when the denim fabric is produced, the warp yarn 001 is the hydroxyl cationic cotton yarn of uncellulose fiber, normally slurry dyed into indigo or sulphur color, and the weft yarn 002 is the yarn spun from the hydroxyl cationic cotton of cellulose fiber; the woven denim can be reactively dyed in the washing water according to the color required by the customer. At this time, because the weft yarn 002 is the yarn of the hydroxyl cationic cotton of cellulose fiber, only the The weft yarn 002 can be dyed, while the warp yarn 001 is ordinary cotton yarn and is not dyed, so the color of the warp yarn 001 itself remains unchanged, so that the resulting trousers can become the base of the colored weft. After being cut or worn, the color of the colored weft will also appear on the surface of the trousers, adding artistic charm to the trousers; providing customers with flexible color matching space, customers can take out any number of trousers of the same fabric style for washing and color matching according to the market needs at the time, and the trousers can be shipped in just 1-2 days. One style can be matched with multiple colors of washing, so as to obtain a rich series of colored-base jeans, which greatly improves the flexibility of production and sales and can meet the needs of today's fast-paced market. By the same principle, the warp yarn 001 is made of yarn spun from hydroxyl cationic cotton of cellulose fiber, and the weft yarn 002 is made of ordinary pure cotton yarn or ordinary cotton and fiber blended yarn to weave white denim fabric. Customers can perform active dyeing in the washing water according to their desired color. At this time, because the warp yarn 001 is yarn of hydroxyl cationic cotton of cellulose fiber, only the warp yarn 001 can be dyed, and the weft yarn 002 is ordinary cotton yarn, so the color will not be colored and remains white. The obtained pants can be turned into colored jeans with colored warp surface, providing customers with flexible color matching space. Customers can take out any number of pants of the same fabric style for washing and color matching according to the needs of the market at that time, and they can be shipped in 1-2 days. One style can be matched with multiple color washes to obtain a rich series of jeans with colored bottoms or colored surfaces, which greatly improves the flexibility of production and sales and can meet the fast-paced needs of today's market. It perfectly solves the problem of fabrics that previously required a colored base or colored surface, which could only be achieved by dyeing the warp yarn or sizing the yarn before weaving. The yarn dyeing and weaving cycle is long, and the delivery cycle is long, which takes at least half a month to a month. Moreover, if the customer does not like the selected color of the woven fabric, it will cause the pain point of unsalable inventory.

[0018] Preferably, the weave structure adopts one of the weave patterns of 3 / 1 right oblique, 2 / 1 right oblique or left oblique, 3 / 1 right oblique or left oblique, 4 / 1 right oblique or left oblique and 5 / 3 satin.

[0019] Furthermore, the first core-spun yarn is a single-core stretch yarn of 100% cellulose fiber hydroxyl cationic cotton-spun spandex, and the second core-spun yarn is a double-core or triple-core stretch yarn of 100% cellulose fiber hydroxyl cationic cotton-spun spandex, a 75D polyester filament and one to two spandex strands.

[0020] Furthermore, the count of the pure cotton yarn or the yarn blended with cotton and regenerated cellulose is 5-40S.

[0021] Furthermore, the count of the hydroxyl cationic cotton of the cellulose fiber is 6-32S, and the D number of the spandex is 20D-140D.

[0022] Preferably, in the yarn blended from cotton and regenerated cellulose fiber, the weight ratio of cotton to regenerated cellulose fiber is 50:50. In addition, one of 80:20, 70:30, 65:35, 60:40, 40:60, and 30:70 can also achieve good results.
