AI Technical Summary

Benefits of technology

This new type of elastic materials that are highly effective at preventing bodily injury during an accident or other event involving harmful objects have been developed by combining certain types of polymers together into one structure called High Density PolyEthylene (HDPE). These special plugs allow for flexibility while still being strong enough when they come off their ends. They may even work well on clothes like those worn over firearms but don’t hurt anyone else because these materials won't break down easily due to environmental concerns.

Problems solved by technology

This patents describes different types of stabs that resist damage from sharp items like tools during use. However, current designs lack both durability and comfortable fit due to their low resistance compared to harder ones. Therefore there needs an improvement in this area.

Embodiment 1

[0028] This embodiment provides a method for preparing a stab-proof flexible material, which includes the following steps:

[0029] Step 1, preparation of polyethylene mixture cloth layer

[0030] The polyethylene mixture cloth layer is made of ultra-high molecular weight polyethylene short fibers and viscose fibers. The elongation rate is 17-20%.

[0031] The density of UHMWPE staple fiber is 0.97~0.98g / cm 3 , the strength is 2.8-4N / tex, the modulus is 91-140N / tex, and the elongation is 3.5%-3.7%.

[0032] Firstly, the ultra-high molecular weight polyethylene staple fibers are opened, carded, and then formed into a web. In the process of web forming, in order to avoid static entanglement and electrostatic knot phenomenon of ultra-high molecular weight polyethylene staple fibers in the web-laying process, it is necessary to combine viscose fibers and ultra-high molecular weight Polyethylene short fibers are mixed together and transported to form a net. During the proces

Abstract

The invention discloses a preparation method and application of a puncture-proof flexible material. The method comprises the following steps: compounding a polyethylene mixture cloth layer and an ultra-high molecular weight polyethylene non-woven cloth layer through an adhesive, wherein the polyethylene mixture cloth layer is prepared from ultra-high molecular weight polyethylene short fibers and viscose acetal fibers, the length of the viscose acetal fibers is 35-38 mm, the fineness is 0.26-0.29 tex, the tensile strength is 2.15-2.18 cN/dtex, and the elongation at break is 17-20%. The stab-resistant flexible material formed by compounding the high-density polyethylene mixture cloth and the ultra-high molecular weight polyethylene non-woven cloth is light, thin, good in flexibility, good in air permeability, good in protection performance, high in strength and free of fuzzing, and can be used for manufacturing safety protection articles such as stab-resistant clothes, stab-resistant gloves and kneecaps.
