Description

Technical Field

[0001] The utility model relates to the technical field of denim fabrics, in particular to a fade-resistant denim fabric. Background Art

[0002] Denim originated in the western United States and was named after the clothes and pants used by herders. It is usually a thicker yarn-dyed warp twill cotton cloth with dark warp yarn and light weft yarn. Denim was originally only blue and used as canvas, but now it has many different colors and can be used to match different clothes. In the denim fabric market, although cotton is undoubtedly the most important, there are also a series of blended fabrics, such as cotton / polyester 50 / 50 blended fabrics, and fabrics woven with cotton and other fibers or without cotton. These denim fabric products are different from many products on the market, giving consumers a high level of product design and high value-added clothing.

[0003] People are constantly developing fashionable denim fabrics, and obtaining novel appearance, feel and performance through dyeing and finishing. However, the dyeing process consumes a lot of water and energy, and discharges a large amount of wastewater, which easily causes environmental pollution. In addition, the dyed denim fabrics are affected by external environments such as long-term sun exposure and washing, and are more prone to fading than other fabrics. This will not only affect the aesthetics of denim clothing, but may also cause the denim fabrics to gradually lose their unique color and style. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a fabric structure diagram of the anti-fading denim fabric involved in the utility model; DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Combination Figure 1 The present embodiment is described in detail. A fade-resistant denim fabric comprises: a fabric body, the fabric body is interwoven with warp yarns and weft yarns; the fabric structure of the fabric body is a five-up-one-down five-up-two-down variable twill; the warp yarn is a colored polyester fiber yarn with UV resistance function; the weft yarn comprises a first weft yarn and a second weft yarn; the first weft yarn and the second weft yarn are arranged in the order of five first weft yarns: one second weft yarn: five first weft yarns: two second weft yarns. Specifically, in the present embodiment, Sj=2 of the five-up-one-down five-up-two-down variable twill, and the starting point of other warp yarn tissue points is determined according to Sj. One side of the variable twill tissue shows a warp twill, showing the color of the warp yarn.

[0014] Furthermore, the cross-section of the anti-ultraviolet colored polyester fiber is pentagonal. The fiber product with a pentagonal cross-section has a soft luster, a smooth and waxy feel, a light texture, and has the function of resisting pilling.

[0015] The anti-ultraviolet colored polyester fiber is a fiber made by melt spinning polyester chips and color masterbatch. Its processing method not only omits the yarn dyeing process, avoids sewage discharge, changes the traditional processing mode of colored yarn, and the yarn made by it will not fade after washing, but also greatly improves the anti-ultraviolet ability of the fiber and yarn, has good energy-saving sunshade, and blocks ultraviolet rays. It can significantly reduce solar radiation, isolate sunlight and create a comfortable environment. Specifically, in this embodiment, the color of the masterbatch is black.

[0016] Furthermore, the first weft yarn is a polyester core-spun yarn with a special cross-section; the polyester core-spun yarn with a special cross-section has a cross-section polyester staple fiber as the outer fiber and a wavy cross-section polyester filament as the core yarn. The outer edge of the cross-section polyester fiber has irregularly distributed grooves; the cross-section of the wavy cross-section polyester filament is four approximately circular cross-sections connected side by side, and there are six grooves of basically the same depth in the longitudinal direction; the longitudinal surface grooves of the polyester fiber with a special cross-section are conducive to the evaporation of water and have good moisture conduction performance, so the polyester core-spun yarn with a special cross-section has a significant improvement in the moisture conduction and quick-drying performance of the fabric.

[0017] Furthermore, the second weft yarn is a flax colored polyester filament wrapped composite yarn; the flax colored polyester filament wrapped composite yarn has a colored polyester network yarn as an outer wrapped yarn and a flax bleached yarn as a core yarn. The flax colored polyester filament wrapped composite yarn has a linen color appearance, the core yarn has a large wrapping twist at the thick section and a light color, and a small twist at the details and a dark color, and there is a weak color effect along the length direction. Specifically, in this embodiment, the colored polyester network yarn is black, and the flax colored polyester filament wrapped composite yarn can give the fabric a color appearance, and no dyeing process is required, which avoids the occurrence of fabric fading after washing.

[0018] Furthermore, mosquito repellent and antibacterial finishing agents are attached to both sides of the fabric body. Specifically, the formula of the mosquito repellent and antibacterial finishing agent is: 12% permethrin, 12% diethylene glycol butyl ether, 70% EL-40, and 6% 1,2-benzisothiazolin-3-one. This finishing agent combines mosquito repellent and antibacterial properties, and can protect the human body from mosquito bites.

[0019] The warp yarn and the second weft yarn of the anti-fading denim fabric are both colored yarns, and the first weft yarn also uses undyed raw white yarn. The yarn has not undergone a dyeing process, which can prevent the fabric from fading after washing. The warp yarn has good UV resistance, which can prevent the fabric from fading after long-term sun exposure. In addition, the first weft yarn also has a good moisture conduction and perspiration function. When the anti-fading denim fabric is made into clothing, the comfort of the user can be improved.
