[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0021] As Figure 1As shown in the figure, a high-strength, low-shrinkage and impact-resistant woven fabric includes: an upper layer 1 and a lower layer 2. The upper layer 1 is arranged on one side of the lower layer 2. When making clothing, the upper layer 1 is the side away from the human body, and the lower layer 2 is the side close to the human body.
[0022] Among them, as Figure 2 shown, the upper layer 1 is formed by the interweaving of warp yarns and weft yarns. The warp yarns include a first warp yarn 11 and a second warp yarn 12. The first warp yarn 11 is an aramid filament, and the second warp yarn is a ultra-high molecular weight polyethylene fiber yarn. The arrangement ratio of the first warp yarn 11 and the second warp yarn 12 is 3-5:1. In this embodiment, the arrangement ratio of the first warp yarn 11 and the second warp yarn 12 is 3:1. The weft yarns include a first weft yarn 13 and a second weft yarn 14. The first weft yarn 13 is an aramid filament, and the second weft yarn 14 is a ultra-high molecular weight polyethylene fiber yarn. The arrangement ratio of the first weft yarn 13 and the second weft yarn 14 is 3-5:1. In this embodiment, the arrangement ratio of the first weft yarn 13 and the second weft yarn 14 is 3:1.
[0023] At the same time, a flame retardant finishing agent layer is attached to the surface of the above ultra-high molecular weight polyethylene fiber yarn to make it have good flame retardant performance. The flame retardant finishing agent layer is obtained by impregnating the ultra-high molecular weight polyethylene fiber yarn with a flame retardant finishing agent.
[0024] The upper layer 1 is formed by the spaced arrangement of aramid filaments and ultra-high molecular weight polyethylene fiber yarns, making the upper layer 1 have extremely high strength and excellent wear resistance, which can meet the durability requirements of work clothes. At the same time, the high-strength and high-modulus fibers make the fabric have the ability to prevent punctures, which can prevent the body from being punctured by sharp objects during work and improve safety.
[0025] The lower layer 2 is formed by the interweaving of warp yarns and weft yarns. Among them, the warp yarns include a third warp yarn and a fourth warp yarn. The third warp yarn is an antistatic composite yarn, and the fourth warp yarn is a high-strength and comfortable composite yarn. The arrangement ratio of the third warp yarn and the fourth warp yarn is 3-5:1. In this embodiment, the arrangement ratio of the third warp yarn and the fourth warp yarn is 3:1. The weft yarns include a third weft yarn and a fourth weft yarn. The third weft yarn is an antistatic composite yarn, and the fourth weft yarn is a high-strength and comfortable composite yarn. The arrangement ratio of the third weft yarn and the fourth weft yarn is 3-5:1. In this embodiment, the arrangement ratio of the third weft yarn and the fourth weft yarn is 3:1.
[0026] As Figure 3 shown, the antistatic composite yarn is formed by the twisting and doubling of ramie fiber yarn 15 and conductive filament 16. The ramie fiber yarn 15 has characteristics such as antibacterial, moisture absorption and breathability, toughness and mildew resistance, softness and comfort, and antistatic. The conductive filament 16 has good antistatic ability. The combination of the two makes the lower layer 2 of the fabric have good comfort and excellent antistatic ability. Preferably, the conductive filament 16 is a carbon fiber yarn. The carbon fiber yarn not only has good conductivity, but also has high strength performance, which can improve the overall strength of the fabric to improve applicability.
[0027] As shown Figure 4 in the figure, the high-strength and comfortable composite yarn includes a core yarn 17 and a wrapping yarn 18 spirally wound around the outside of the core yarn. The core yarn 17 is a ultra-high molecular weight polyethylene fiber yarn, and the wrapping yarn is a ramie fiber yarn. The combination of the ramie fiber yarn and the ultra-high molecular weight polyethylene fiber yarn can ensure the comfort and high strength of the lower layer 2 weft yarns, and improve the overall strength and puncture resistance of the fabric.
[0028] Meanwhile, the antistatic composite yarn and the high-strength and comfortable composite yarn are coated with a flame retardant finishing agent layer on the surface, so that the lower layer 2 has flame retardant properties to improve the overall flame retardant ability of the fabric. The flame retardant finishing agent layer is prepared by impregnating the yarn with a flame retardant finishing agent solution.
[0029] A hydrophobic coating 3 is coated on the side of the upper layer 1 away from the lower layer 2, so that the surface layer of the fabric has certain hydrophobic properties, which can enhance the hydrophobic and dirt-resistant ability of the fabric. The hydrophobic coating 3 is applied to the surface of the upper layer 1 by a spraying process.
[0030] In addition, the above-mentioned aramid filament is coated with a graphene wear-resistant coating to improve the wear resistance of the upper layer 1 of the fabric.
[0031] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art shall be within the protection scope determined by the claims.
