Problems solved by technology

These two types of stab-resistant clothing have excellent stab-resistant performance, but are hard and bulky and have poor flexibility
The third category is flexible stab-resistant clothing produced by processing high-performance fibers such as aramid fiber and UHMWPE. The stab-resistant performance is good, but the thickness is thick, the air permeability is poor, and the cost is high.
However, due to this molding process, the garment fabric is laid under the metal mesh, and the metal mesh is easily deformed due to internal stress. The surface of the garment fabric is pasted together, and the comfort and softness will be reduced to a certain extent

Abstract

The invention relates to a bonding forming method of a flexible stab-preventing material and a stab-preventing body. Particle patterns are formed on base cloth in a bonding mode, the thickness of particles ranges from 0.3 mm to 2 mm, the distance between any two points ranges from 1 mm to 20 mm according to the horizontal plane size, and the separation distance between every two adjacent particle patterns ranges from 0.2 mm to 2 mm. The bonding forming method of the flexible stab-preventing material and the stab-preventing body comprises the steps that the particles are evenly scattered in mold holes of a mold, a piece of film with even holes is fixed, the particles in the mold are evenly coated with adhesives, the film is torn away, extra adhesives in gaps between the particles are removed, base cloth fabric is laid, heating solidification is carried out, the particles solidify on the base cloth, and the flexible stab-preventing material is obtained. The flexible stab-preventing material has high mechanical strength, and can resist piercing of common knives and common syringes; due to the fact that gaps exist between the particle patterns, it is ensured that the obtained flexible stab-preventing material has good flexibility performance and good air permeability, safety protection articles such as stab-preventing vests, stab-preventing jackets, stab-preventing arm guards, stab-preventing kneecaps and stab-preventing gloves can be made of the flexible stab-preventing material, and application is wide.

Description

[technical field] [0001] The invention relates to a manufacturing method of a stab-proof material, in particular to a flexible stab-proof material and a bonding molding method of a stab-proof body. [Background technique] [0002] In recent years, the occurrence of international violence and terrorist incidents has made people more and more aware of the importance of their own security protection, and the state has also increased its support for the field of security protection. Many countries, including my country, have very strict control over guns, but threats from sharp weapons such as daggers and bayonets are ubiquitous. Therefore, high-risk occupational groups such as public security, civilian police, security guards, and urban management are in urgent need of advanced stab-resistant clothing with good stab-proof performance, comfort, softness, flexibility and lightness. [0003] There are mainly three types of stab-resistant clothing produced by stab-resistant materia...
