Problems solved by technology

The price of Kevlar with a fineness of less than 800D is relatively expensive, and it is rarely used in domestic stab-resistant clothing.
Coarse denier yarns are mostly used in UHMWPE, and fine denier yarn fabrics have disadvantages such as excessive twist, too low weaving density, and insufficient strength to make full use of them.

Abstract

An antiprick composite fabric with high flexibility and light weight is made of the ultrahigh-molecular-weight polyethene yarns and is composed of a coated woven layer, an overlapped layer of non-woven fabric and woven fabric, which are crossed in weft direction, a non-weft fabric layer, and an overlapped layer of non-woven fabric and woven fabric, which are crossed in warp direction. It features that all the layers can be relatively shifted. Its advantages are high antiprick effect and high strength.

Description

technical field [0001] The invention relates to a functional fabric and a manufacturing method thereof, in particular to a flexible and lightweight composite anti-stab fabric and a manufacturing method thereof. Background technique [0002] Stab-resistant clothing currently on the market is divided into two types: hard and soft. [0003] Hard stab-resistant clothing contains rigid materials such as metal wires, metal meshes, and ceramic sheets, which have disadvantages such as heavy weight, poor flexibility, and uncomfortable wearing. [0004] Flexible stab-resistant clothing mainly uses high-strength and high-modulus fibers such as Kevlar and ultra-high molecular weight polyethylene (UHMWPE) as raw materials. The price of Kevlar with a fineness of less than 800D is relatively expensive, and it is rarely used in domestic stab-resistant clothing. Coarse denier yarns are mostly used in UHMWPE, and fine denier yarn fabrics have disadvantages such as excessive twist, too small...
