Problems solved by technology

[0006] The purpose of the present invention is to provide a composite multi-layer stab-proof bullet-proof cloth sheet and its preparation method, to solve the current problem proposed by the above-mentioned background technology that it is difficult to have a stab-proof bullet-proof cloth that can simultaneously meet the needs of stab-proof and bullet-proof for protective use. At the same time, most of the stab-proof and bullet-proof fabrics have a rough structure, which cannot guarantee the stab-proof and bullet-proof effects, and the composite effect is poor, which cannot guarantee long-term use, and most of the bullet-proof vests are relatively thick, which will seriously affect the flexibility of wearing and using.

Abstract

The invention discloses a composite multi-layer stab-resistant bulletproof fabric piece and a preparation method thereof. The stab-resistant bulletproof fabric piece is formed by weaving and compounding high-performance fibers such as ultra-high molecular weight polyethylene fibers, aramid fibers, carbon fibers and PBO fibers and a small amount of elastomer fibers; the elastomer fibers are polybutylene terephthalate fibers; and the preparation method comprises the following steps of uniformly blending the ultra-high molecular weight polyethylene fibers, the aramid fibers, the carbon fibers, the PBO fibers and a small amount of polybutylene terephthalate fibers, and then carrying out composite hot pressing. According to the composite multi-layer stab-resistant bulletproof fabric piece and the preparation method thereof, hot-pressing gluing is conducted after blending, structure increasing is facilitated, meanwhile, through uniform blending of different kinds of fiber filaments, the overall structural performance of the stab-resistant bulletproof fabric piece can be enhanced, the overall mass density of the stab-resistant bulletproof fabric piece can be reduced, the toughness, the shaping performance, the elasticity and other performance are improved, the wearing and using comfort and flexibility can be improved, and the composite multi-layer stab-resistant bulletproof fabric piece is suitable for use in security operations.

Description

technical field [0001] The invention relates to the technical field of stab-proof and bullet-proof cloth, in particular to a composite multi-layer stab-proof and bullet-proof cloth and a preparation method thereof. Background technique [0002] Stab-proof body armor is a common protective equipment for individual soldiers. Stab-proof clothing is also called knife-resistant clothing, blade-resistant clothing or blade-resistant clothing. Scratch, wear resistance, anti-theft and other functions. When wearing knife-resistant clothing, it can protect the wearer from being cut, scratched, rubbed, or chopped in case of abrasion or when cutting, cutting, chopping, scraping, scratching, or scratching with a sharp knife (sharp blade, sharp object, etc.). [0003] Body armor, also known as bulletproof vest, bulletproof vest, bulletproof vest, bulletproof clothing, individual body armor, etc., is used to protect the human body from bullets or shrapnel. Body armor is mainly composed of...
