Light flexible liquid stab-proof material and preparation method thereof

Abstract

The invention discloses a light flexible liquid stab-proof material. Ultrahigh molecular weight polyethylene yarn or aramid fibre is adopted as a raw material to solve the problems of thickness and heaviness, poor comfort and high manufacture cost of the existing stab-proof material. The material is compounded by high strength fiber non-weft cloth, a high strength fiber three-dimensional hollow-structured fabric and liquid with a shear thickening feature by a hot sewing technology, and is in a flexible liquid state when not stressed. Once being impacted, the material hardens and when the impact force disappears, the material restores to the flexible liquid state. The three-dimensional hollow fabric structure can be effectively solving the problem that the original protective materials freely slide after being stacked, playing a role of a bracket and lowering the weaving cost. The non-weft cloth comprises high-performance fiber composite non-weft cloth and a bag-shaped sealed fabric is produced by a hot sewing technology, so the shear thickening liquid leakage problem can be solved. The stab-proof material combines the compression elasticity of the three-dimensional hollow-structured fabric, the anti-leakage property of the non-weft cloth, the feature of shear thickening liquid and the technical advantages of hot sewing, is simple in process and convenient to operate, can effectively protect hurt caused by sharp instruments such as daggers and bayonets, adopts fewer lighter raw materials to motility to ensure the flexibility of a human body in danger, and is not only applicable to supervising officers, city management officers and the like in the police security departments, but also applicable to the civil field such as sports protection (protective clothing for fencing and the like), industrial staff protection (decoration, construction and the like), protection for fishing people and racing drivers of motorcycles, and security protection for cab drivers.

Description

Technical field [0001] The invention belongs to the field of personal protective armor materials. In particular, it relates to a light and soft liquid anti-stab material and a preparation method thereof. Background technique [0002] With the development of society and technology, anti-stab materials have entered people's daily life. People have higher and higher requirements for stab-resistant materials, and the heavy and hard stab-resistant clothing can no longer meet people's needs, so semi-rigid stab-resistant clothing has appeared. Semi-rigid stab-proof clothing is a kind of stab-proof clothing with certain flexibility. This kind of stab-proof clothing is composed of several layers of materials, with one or several layers of special metal sheets or wire ring interlayers in the middle. Improve the flexibility of people's activities. In recent decades, soft stab-resistant clothing has appeared. At present, the traditional soft stab-resistant materials at home and abroa...

AI Technical Summary

Problems solved by technology

In recent decades, soft stab-resistant clothing has appeared. At present, the traditional soft stab-resistant materials at home and abroad are generally composed of 20-40 layers of aramid fiber or ultra-high molecular weight polyethylene fiber fabrics. Due to the large number of layers , there are still disadvantages such as high production cost, bulky quality, poor flexibility and poor comfort
