Description

Technical Field

[0001] This utility model relates to denim fabrics, and more particularly to cotton / polyester reactive dyeing non-fading denim fabrics. Background Technology

[0002] Since the late 1970s, denim has undergone several major developments in China, making it a major producer of denim fabrics internationally. A large number of advanced denim fabric and clothing companies have basically reached international standards in terms of quality and variety, initially reversing the perception that Chinese denim products are "low-end" in the international market.

[0003] When making clothing from denim fabric, rips are often added to create unique distressed denim garments and enhance their aesthetics. However, existing denim fabrics are generally made by weaving together a twill weave before creating rips and adding frayed details at the rips. Because the rips are created after the weave is completed, the fabric's structure is damaged, resulting in poor structural strength at the rips. As the rips grow larger during wear and washing, they negatively impact the appearance. In addition, the dyed parts of existing denim fabrics are in direct contact with the outside, and rubbing against other items during use can cause color fading. Utility Model Content

[0004] In view of the shortcomings of existing technologies, such as poor strength at the opening of holes in fabrics after tearing and easy fading of dyed parts due to friction, this utility model provides a cotton / polyester reactive dyed non-fading denim fabric.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: cotton / polyester reactive dyeing non-fading denim fabric, including a first yarn and a second yarn in a loop, the first yarn is set in a loop structure in the even-numbered columns of the first row, the second yarn is set in a loop structure in the base-numbered columns of the first row, the first yarn is set in a loop structure in the technical columns of the second row, and the second yarn is set in a loop structure in the even-numbered columns of the second row. In the same column, the loop structure of the previous row passes through the loop structure of the next row, wherein the first yarn and the second yarn are both cotton / polyester and the cotton / polyester surface is covered with water-soluble yarn.

[0006] Preferably, the first yarn is arranged in loops in column K of the first row, column K-1 of the second row, column K of the third row, and column K+1 of the fourth row, and repeats in this pattern, with K as the base number.

[0007] Preferably, the second yarn is arranged in loops in the first row, column K+1, the second row, column K+2, the third row, and column K of the fourth row, and repeats in this pattern.

[0008] Preferably, in the same row, the looped structure of the upper row is threaded onto the back of the looped structure of the lower row.

[0009] Preferably, the polyester / cotton blend has a fineness of 165 dtex and a single fiber fineness of 0.76–1.0 dtex.

[0010] Preferably, after coating, the water-soluble yarn on the surface of the polyester / cotton blends at a 45-degree angle to the polyester / cotton blend.

[0011] Preferably, polyester / cotton blends are impregnated on the surface to form a dye layer.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This application can be selected according to the needs of garment production. At the location where a hole structure is required, the interlaced loop structure in this application naturally forms the hole during the weaving process, so that the formed hole structure has no broken threads, thereby improving the structural strength. In addition, by setting water-soluble yarn on the surface of cotton / polyester, flocculent material can be formed in water at a certain temperature. The flocculent material will extend to the hole, eliminating the need for additional setting. Furthermore, the water-soluble yarn covering the cotton / polyester can provide a certain degree of protection for the dye layer on the surface of cotton / polyester, avoiding the phenomenon of color fading due to friction.

[0018] Example

[0019] Cotton / polyester reactive dyeing colorfast denim fabric, such as Figure 1-2As shown, it includes a first yarn 10 and a second yarn 20 in a loop. The first yarn 10 is arranged in a loop structure 01 in the even-numbered column of the first row, and the second yarn 20 is arranged in a loop structure 01 in the digited column of the first row. The first yarn 10 is arranged in a loop structure 01 in the technical column of the second row, and the second yarn 20 is arranged in a loop structure 01 in the even-numbered column of the second row. The loop structure 01 of the previous row in the same column passes through the loop structure 01 of the next row. The first yarn 10 and the second yarn 20 are both cotton / polyester and the cotton / polyester surface is covered with water-soluble yarn.

[0020] Preferably, the first yarn 10 is set into loop structure 01 in column K of the first row, column K-1 of the second row, column K of the third row, and column K+1 of the fourth row, and repeats this pattern, with K as the base number. Since the weaving is continuous, K can take a negative value.

[0021] Preferably, the second yarn 20 is set into loop structure 01 in the first row, column K+1, the second row, column K+2, the third row, and column K of the fourth row, and repeats in this pattern.

[0022] Preferably, in the same row, the looped structure 01 of the previous row is inserted on the back of the looped structure 01 of the next row.

[0023] Preferably, the polyester / cotton blend has a fineness of 165 dtex and a single fiber fineness of 0.76–1.0 dtex.

[0024] Preferably, after coating, the water-soluble yarn on the polyester / cotton surface forms a 45-degree angle with the polyester / cotton. Setting it to a 45-degree angle ensures moderate elasticity after coating.

[0025] Preferably, a dye layer is formed on the surface by impregnation of polyester / cotton. The dye layer is located on the polyester / cotton, so that the water-soluble yarn covering the polyester / cotton provides a certain degree of protection for the dye layer, which can prevent color fading due to friction.

[0026] It should be noted that, Figure 1 The diagram shows several rows and columns, with four rows forming a cycle. The dashed line is the cycle boundary line where a cycle ends.
