Technical Field

The invention relates to the technical field of stab-resistant clothes, and particularly belongs to a fabric for stab-resistant clothes and a preparation method thereof.

Background

The stab-resistant clothing is also called knife-resistant clothing, edge-resistant clothing or edge-resistant clothing, and has the functions of knife cutting resistance, knife chopping resistance, knife stabbing resistance, scraping resistance of angular objects, wear resistance, theft prevention and the like. When wearing the knife-proof coat, the coat can be cut, scraped, rubbed and scratched by a sharp knife (sharp edge, sharp object and the like) or the coat can be prevented from being cut, scratched, rubbed and cut by a wearer when being worn, and the knife-proof coat is suitable for being worn by workers such as public security, armed police, army, security guard, drivers, glass processing and the like or the old, children, middle and primary school students at the risk of being cut.

Present stab-resistant clothing all has multilayer structure to constitute, in order to strengthen the protective capacities of stab-resistant clothing, use the wire even in the majority stab-resistant clothing, although the performance of preventing stab-resistant clothing has obtained promoting by a wide margin, nevertheless prevent stab-resistant clothing and be too bulky, be not convenient for dress, other protective clothing realizes the reinforcing simultaneously mainly through the number of piles that increases protective clothing, caused protective clothing overweight like this, and the increase of protective clothing surface fabric number of piles can lead to the reduction of protective clothing gas permeability, therefore, need to design a number of piles less, stab-resistant layer performance is good, the protective clothing surface fabric that the gas permeability is good, it is more comfortable to make the protective clothing of dress.
