Embodiment 1

[0088] A kind of production technology of anti-stab fabric, comprises the following steps:

[0089] 1. Raw material performance test and analysis:

[0090]Single-yarn performance tests were performed on high-strength polyester filaments and ultra-high molecular weight polyethylene filaments, and the obtained data were compared, researched and analyzed. The breaking strength of ultra-high molecular weight polyethylene filaments of the same fineness is 3 to 5 times that of high-strength polyester filaments, but the elongation at break is less than half of that of high-strength polyester filaments. When high-strength polyester filaments are tested When the elongation at break of the ultra-high molecular weight polyethylene filament is reached, the force it bears is only about 40% of its own breaking strength. The difference in breaking strength and elongation at break of the two raw materials provides a new idea for the design of the fabric structure and the design of the yarn r...

[0146] A kind of production technology of anti-stab fabric, comprises the following steps:

[0147] 1. Raw material performance test and analysis:

[0148] Single-yarn performance tests were performed on high-strength polyester filaments and ultra-high molecular weight polyethylene filaments, and the obtained data were compared, researched and analyzed. The breaking strength of ultra-high molecular weight polyethylene filaments of the same fineness is 3 to 5 times that of high-strength polyester filaments, but the elongation at break is less than half of that of high-strength polyester filaments. When the elongation at break of ultra-high molecular weight polyethylene filament, the force it bears is only about 40% of its own breaking strength. The difference in breaking strength and elongation at break of the two raw materials provides a new idea for the design of the fabric structure and the design of the yarn ratio.

Abstract

The present invention discloses a production process of puncture-proof fabrics. The ultrahigh molecular weight polyethylene filament and high-tenacity polyester filament yarns are taken as raw materials, the performance difference of the ultrahigh molecular weight polyethylene filaments and the high-tenacity polyester filament yarns is analyzed to determine the specifications of the ultrahigh molecular weight polyethylene filaments and the high-tenacity polyester filament yarns and determine the yarn usage amount of the two, through the organization structure design of the fabrics, numbers ofpaths of the ultrahigh molecular weight polyethylene filaments are reasonably distributed, a weaving process employs a weft knitting mode for weaving, a coil structure is employed to perform advantagecomplementation of the two raw materials so as to solve the problem that the ultrahigh molecular weight polyethylene filaments are difficult to weave, the weaved fabrics are processed through adoption a after treatment process to produce a finished product. The novel puncture-proof fabrics by taking the ultrahigh molecular weight polyethylene filaments and the high-tenacity polyester filament yarns as the raw materials are good in breathability, wearing comfort, flexibility and economy.

Description

Technical field: [0001] The invention relates to a stab-proof fabric, in particular to a production process of a stab-proof fabric, belonging to the technical field of special fabric production. Background technique: [0002] Although we are in a peaceful age, violent conflicts, terrorist attacks and other incidents still occur in various countries around the world. With the improvement of people's awareness of protection and anti-terrorism, personal protection has become a hot topic worldwide, and stab-resistant fabrics play an extremely important role in personal protection. [0003] Most of the traditional stab-proof fabrics use metal sheets and wires, and most of them are formed by thermal bonding or stitching of multi-layer fabrics, such as a kind of police protective clothing in patent CN 106490716 A. Because it contains metal components and is composed of multiple layers, the preparation process is complicated, the air permeability and wearing comfort are not good, t...
