Problems solved by technology

However, the shear thickening fluid in this stab-resistant fabric is solid, and the resulting stab-resistant fabric is relatively rigid, which will limit the movement of the human body
In CN202648534U, it is proposed to coat the shear thickening fluid with non-woven fabric and adhesive, although this stab-proof fabric is not too easy to leak, but the wearing comfort is poor

Abstract

The invention provides an anti-stab fabric with shear thickening fluid and rheid. The fabric is characterized by comprising a three-dimensional-structure fabric as a framework structure, the three-dimensional-structure fabric is provided with a cavity, and the cavity of the three-dimensional-structure fabric is filled with the shear thickening fluid. According to the anti-stab fabric, since the viscosity of the shear thickening fluid is rapidly increased at high shear speed, and the shear thickening fluid has an energy consumption characteristic of liquid and high strength performance of a solid, the novel anti-stab fabric for the rheid, particularly the anti-stab fabric for the shear thickening fluid and rheid is provided. The shear thickening fluid is injected into the three-dimensional-structure fabric, if the fabric is subjected to any impact or shearing force, the viscosity of the shear thickening fluid is quickly increased, the shear thickening fluid is in a solid state, and accordingly the anti-stab function is achieved.

Description

technical field [0001] The invention is applied in the stab-proof field and relates to a novel shear-thickening fluid soft protective fabric. Background technique [0002] In relatively dangerous careers such as public security and armed police, they protect the safety of the people of the country, but they are often accompanied by high risks (such as stab wounds). Therefore, there is often a large demand for clothing that can play a stab-proof and protective role. At present, there are many developments and researches on stab-proof materials at home and abroad, such as titanium metal foil layer, which is stab-proof but relatively heavy. In addition, some rigid metals, ceramics or composite plates may be used. Although these materials can provide good stab resistance, they are bulky, inflexible, uncomfortable to wear and poor in concealment. In order to balance the stab resistance and flexibility of protective materials, the emergence of a new type of stab-resistant fabric—...
