Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a lightweight tear-resistant fabric. Background Art

[0002] Nylon filament fabrics are flat and fine, smooth and soft to the touch, thin and light, strong and wear-resistant, easy to wash and dry, and are mainly used as fabrics for down jackets, casual jackets, etc. However, due to being too thin and light, they have poor tear resistance and are prone to rapid fracture spread after being damaged. In order to solve this problem, existing technologies mainly improve their tear resistance by adding an anti-tear layer or other materials.

[0003] Patent CN214983872U discloses a nylon spunlace with good tear resistance, in which a tear resistance layer composed of stainless steel metal fiber and aramid fiber is bonded to the outside of the nylon fabric substrate layer, thereby improving the tear resistance of the nylon spunlace; CN219749091U discloses a nylon spunlace with good tear resistance, in which an elastic layer is added to the outer side of the nylon spunlace main body layer, and a porous structure is provided on the front of the elastic layer, and a high elastic layer made of polyacrylate fiber is connected to the outside of the nylon spunlace main body layer, so that the nylon spunlace has strong elasticity and toughness, and the tear resistance of the fabric is greatly improved in tearing conditions such as sports; CN113201840A discloses A tear-resistant graphene nylon fiber fabric and a preparation method thereof, wherein graphene-modified nylon fiber is used as the warp direction and TPU nanofiber is used as the weft direction, and the tear-resistant graphene nylon fiber fabric is formed by alternating the warp and weft of modified reinforcing yarns; CN204550918U discloses a tear-resistant and wear-resistant fabric, wherein the structural unit of the tear-resistant and wear-resistant fabric is composed of eight warp yarns and weft yarns interwoven, wherein the warp yarns in the structural unit are two nylon / para-aramid mixed yarns (626D) from left to right and the weft yarns are two nylon / para-aramid mixed yarns (626D) from top to bottom, and the tear resistance of the fabric is improved by local reinforcement of the coarse denier special yarn.

[0004] The above existing technologies, while improving the tear resistance of nylon filaments, often increase their weight, affecting their softness and comfort; or, due to the different dyeing properties of different materials, adding other materials will affect the dyeing effect of the fabric. Therefore, how to improve the tear resistance of nylon filament fabrics while maintaining their original advantages is an important challenge facing current technologies.

[0030] In this embodiment, the yarns of the first warp yarn system 1 and the first weft yarn system 3 are common nylon filaments with a fineness of 20D and a yarn strength of 5.5 cN / dtex.

[0031] In this embodiment, the yarns of the second warp yarn system 2 and the second weft yarn system 4 are high-strength fine-denier nylon 66 filaments with a fineness of 40D, and the yarn strength is 7.2 cN / dtex.

[0032] In this embodiment, the yarns of the first warp yarn system 1 and the first weft yarn system 3 are interwoven into a plain weave.

[0035] A ZW8100 Tsudakoma water jet loom was used for weaving, and the loom speed was set to 800 rpm. High-strength fine-denier nylon 66 filaments were woven into the common nylon filaments according to a certain rule: in the warp and weft directions, one high-strength fine-denier nylon 66 filament was woven into the fabric every 3 mm, and the warp density of the prepared lightweight tear-resistant nylon 66 fabric (No. A) was 500 strands / 10 cm, and the weft density was 500 strands / 10 cm.
