Abstract

The invention provides a resin-free soft puncture-proof material, and relates to the technical field of protective equipment. The soft puncture-proof material provided by the invention comprises a cutting-proof layer and / or a puncture-proof layer, wherein when the soft puncture-proof material comprises the anti-cutting layer and the puncture-proof layer, the puncture-proof layer is overlaid on thesurface of one side of the anti-cutting layer; the anti-cutting layer is formed by overlaying 5-50 pieces of wrap yarn fabric; each piece of wrap yarn fabric is formed by plain weaving of one or morekinds of wrap yarns; the wrap yarns sequentially comprise core layers (Kevlar or UHMWPE fiber), first wrap yarn layers (PA or PU fiber) and second wrap yarn layers (Kevlar or UHMWPE fiber) from inside to outside; the puncture-proof layer is formed by overlaying 1-10 pieces of three-dimensional fabric; and the fiber material of each piece of three-dimensional fabric is UHMWPE fiber or Kevlar fiber. The soft puncture-proof material provided by the invention has the characteristics of light weight, softness, comfort in wearing and good puncture-proof effect.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to a resin-free soft stab-proof material. Background technique [0002] The development of stab-resistant materials has gone through three stages so far, and the corresponding products are hard stab-resistant materials, semi-rigid stab-resistant materials and soft stab-resistant materials. The early hard and semi-rigid stab-proof materials were mainly made of metal materials or composited with metal materials and fiber fabrics. This kind of stab-proof materials have excellent stab-proof performance, but they generally have the disadvantages of being bulky and inflexible to wear. Its promotion and commercial application are limited. In the 21st century, soft stab-resistant materials made of high-performance fibers such as UHMWPE and Kevlar and their composite materials have become the main force in the field of protection. Much lighter. [0003] Existing soft anti-sta...
