Why can stab-proof clothing be stab-proof?

First of all, let me talk about it. According to the degree of softness and hardness, stab-resistant clothing can be divided into soft stab-resistant clothing and hard stab-resistant clothing. Their materials are different, so the stab-resistant principle of stab-resistant clothing lies in the stab-resistant material. and puncture-resistant liner.
The soft stab-resistant clothing is composed of a stab-resistant jacket, a stab-resistant layer, and a stab-resistant protective cover. The structure of the stab-resistant clothing is as follows from the outside to the inside: 36 layers of high-performance polyethylene fiber non-weft fabric (two layers of fiber orthogonal )+5mm thick foam board, which is packaged in the protective sleeve by heat sealing process. The product uses a uniform stab-proof layer, and the shoulders and waist are connected with brocade buckle straps to adjust the size of the shoulders and waist. The coat is black and sealed impervious to water and light. It can effectively resist the puncture of sharp objects such as knives, daggers, and triangular scrapers. The anti-stab strength is greater than 24 joules. Regulations on stab-proof clothing.
The liner material of the hard anti-stab suit is high-manganese steel sheet, which is made of high-manganese steel and has been quenched and refined, so it has strong protection ability. The steel plate of the inner tank adopts the typesetting of the bionic fish scale structure, which cannot be pierced by a sharp knife. The jacket fabric is made of 600D nylon cloth, which is strong waterproof and sweat-wicking, not easy to wear, and very durable.
