Problems solved by technology

Traditional anti-stab materials are thick, bulky, and inflexible. They can only protect the torso of the limbs, but cannot effectively protect some joints such as knees. Faced with the contradiction between protection performance and flexibility, in recent years With the emergence of high-performance synthetic fibers such as Kevlar, UHMWPE, PBO, and carbon fiber, high-performance fibers can also be used to make light, flexible, and easy-to-wear stab-resistant materials. The air permeability and comfort are poor, especially in the high temperature state in summer, it will be extremely stuffy. If the content of high-performance synthetic fibers is reduced, the stab resistance performance will decrease

Abstract

The invention discloses a stab-resistant protective fabric containing ice-cold materials. The main point of the technical scheme is that the protective material is made of ultra-high molecular weight polyethylene fiber, aromatic polyamide fiber, polyparaphenylene benzobisoxazole fiber, carbon fiber , high-strength polyester fiber, and any plain fabric imitating spider silk fiber is the base layer, and the base layer is set in multiple layers; the fibers on the base layer are blended with Coolking fiber or Coolplus fiber that can absorb moisture and sweat; on the base layer The shear thickening fluid is evenly attached to the base layer, and the shear thickening fluid is compounded with the base layer by using a static impregnation method. The anti-stab protective fabric has the advantages of softness, breathability, and comfort. Under normal use, it is close to the comfort of ordinary fabrics. Daily office activity needs of staff.

Description

technical field [0001] The invention relates to the technical field of protective materials, more specifically, it relates to a stab-resistant protective fabric containing cold materials. Background technique [0002] With the process of global economic integration, various communication activities are becoming more and more frequent, especially when terrorism and violence are on the rise, people's awareness of self-protection is gradually increasing. Anti-terrorism has become an event that has attracted much attention internationally, especially in developed countries, so the development of personal protection products has also developed rapidly. [0003] For many countries, including my country, the use of firearms is strictly controlled, and military police and security personnel are relatively more threatened by sharp objects such as daggers, awls, and needles, which makes the research and development of stab-resistant materials more and more important. Traditional anti...
