Description

Technical Field

[0001] The utility model relates to denim fabrics, in particular to environmentally friendly coated denim fabrics. Background Art

[0002] Jeans can be worn in many occasions such as outdoor activities, home decoration, work, etc.

[0003] In order to adapt to special scenarios, a special coating is applied to the outside of jeans to increase their wear resistance and flame retardancy.

[0004] However, although coating the surface of denim fabric increases the wear resistance and flame retardancy of jeans, it will increase the hardness of the fabric and reduce the breathability and stiffness of the denim fabric. Utility Model Content

[0005] Based on the disadvantages of the prior art that coating denim fabrics causes reduced breathability, softness and stiffness, the utility model provides an environmentally friendly coated denim fabric.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] Environmentally friendly coated denim fabric includes warp and weft yarns woven in sinking and floating patterns, both of which are coated. The warp yarn includes non-elastic composite yarn; the weft yarn includes an elastic yarn arranged in a central position as a core yarn, two twisted yarns twisted on the elastic yarn, and a covering yarn wrapped around the twisted yarn. The covering yarn is a water-soluble yarn and completely wraps the side of the elastic yarn. The two twisted yarns are twisted in opposite directions. The surfaces of the elastic yarn, twisted yarn and non-elastic composite yarn are coated.

[0008] Preferably, a covering yarn is provided on the surface of the non-elastic composite yarn, and the covering yarn is a water-soluble yarn.

[0009] Preferably, the non-elastic composite yarn is made of two 20 / 22D single yarns combined with 400 twists per meter in the Z direction.

[0010] Preferably, the single yarn is a non-elastic spandex single yarn.

[0011] Preferably, the weft yarn uses 70D elastic spandex as the core yarn and 20D graphene nylon yarn as the sheath yarn, and is twisted in the S direction with 200 twists per meter.

[0012] Preferably, the coating is a water-based transparent coating layer or a nano coating provided by a dipping method.

[0013] Preferably, the water-soluble yarn is water-soluble polyvinyl alcohol fiber.

[0014] Preferably, the warp and weft threads are interwoven perpendicularly.

[0015] Preferably, the weaving points of the warp threads are sequentially one up and one down and in a cycle, and the weft threads are sequentially one down and one up and in a cycle.

[0016] Compared with the prior art, the advantages of the present invention are as follows: the warp in the present application is not elastic, the weft is elastic, and after interweaving, it is not easy to deform vertically, which is conducive to maintaining its shape, and can provide sufficient elasticity in the horizontal direction to improve comfort. In addition, by coating some of the yarns, the wear resistance and flame retardant effect are improved. At the same time, since the coating is set on the yarn, the final fabric has breathable pores, which effectively ensures the breathability of the denim fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1

[0026] This embodiment mainly describes the topic of environmentally friendly coated denim fabrics, as follows:

[0027] Environmentally friendly coated denim fabric, refer to the attached Figures 1-4 , including warp threads 10 and weft threads 20 woven in sinking and floating patterns, both of which are provided with coatings, and the warp threads 10 include non-elastic composite yarns; the weft threads 20 include an elastic yarn 201 as a core yarn arranged at the center position, two twisted yarns 202 twisted on the elastic yarn 201, and a covering yarn 203 wrapped around the twisted yarn 202, the covering yarn 203 being a water-soluble yarn and completely wrapping the side of the elastic yarn 201, wherein the two twisted yarns 202 are twisted in opposite directions, and the surfaces of the elastic yarn 201, the twisted yarn 202 and the non-elastic composite yarn are provided with coatings, wherein the core yarn in the weft thread 20 is used to provide a certain elasticity, and the twisted yarn 202 is used to increase the strength while limiting the elasticity of the core yarn, and the covering yarn 203 is used to increase the width. The warp yarn 10 in this solution is not elastic, while the weft yarn 20 is elastic. After interweaving, it is not easy to deform vertically, which is conducive to maintaining its shape, and can provide sufficient elasticity in the horizontal direction to improve comfort. In addition, by coating some of the yarns, the wear resistance and flame retardant effect are improved. At the same time, since the coating is provided on the yarn, the final fabric has breathable pores, which effectively ensures the breathability of the denim fabric.

[0028] Warp structure :

[0029] Specifically, the non-elastic composite yarn is provided with a covering yarn 203 on its surface. The covering yarn 203 is a water-soluble yarn. Specifically, the water-soluble yarn is a water-soluble polyvinyl alcohol fiber. The water-soluble yarn dissolves in water at about 60 degrees Celsius and forms flocs in water at room temperature, increasing stiffness.

[0030] Specifically, the non-elastic composite yarn is made of two 20 / 22D single yarns twisted 400 times per meter in the Z direction, wherein the single yarn is a non-elastic spandex single yarn.

[0031] Weft structure :

[0032] Preferably, the weft yarn 20 uses 70D elastic spandex as the core yarn and 20D graphene nylon yarn as the sheath yarn, and is twisted in the S direction with 200 twists per meter.

[0033] Coating structure :

[0034] Preferably, the coating is a water-based transparent coating or a nano-coating provided by a dipping method. The water-based transparent coating is used to improve the flame retardancy and abrasion resistance of the fabric, while the nano-coating is mainly used to improve the chemical resistance and abrasion resistance of the fabric.

[0035] Interwoven structure :

[0036] As an example, the warp threads 10 and the weft threads 20 are vertically interwoven. Specifically, the weaving points of the warp threads 10 are sequentially one up and one down and cyclic, and the weaving points of the weft threads 20 are sequentially one down and one up and cyclic.

[0037] The above is a detailed introduction to the environmentally friendly coated denim fabric provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the present invention.
