Abstract

The invention provides a special fiber material for weapons and equipment and a textile fabric with the special fiber material. The special fiber material and the textile fabric have the advantages that aramid fibers are treated by phthalic anhydride and microcrystalline celluloses, accordingly, the polyurethane adhesive bond performance of the aramid fibers can be improved, the aramid fibers are high in bond strength, and the bulletproof performance of the aramid fibers can be improved to a certain extent; modified polyurethane adhesive is coated on the prepared special aramid fibers for the weapons and the equipment after the special aramid fibers are spread and are uniformly, parallelly, straightly and uprightly arrayed, and then the special aramid fibers are dried at the temperatures of 60-80 DEG C to obtain non-woven fabrics with the aramid fibers; the aramid non-woven fabrics are high in strength, excellent in waterproof performance, bulletproof performance and impact-resistant performance and applicable to human body protection and armored protection.

Description

technical field [0001] The invention relates to a fiber material and its fabric, in particular to a special special fiber material and its fabric for weapon equipment. Background technique [0002] In the field of human body protection and weaponry, not only are there requirements for anti-elastic performance, but also high requirements for weight, structural strength and applicability in high and low temperature environments. Therefore, it is necessary to use high-performance fibers with both protective functions and structural strength composite material. [0003] Aramid fiber has the characteristics of high strength, high modulus, good impact resistance, and good chemical stability. Its bulletproof composite materials are widely used in body armor, military vehicles, helicopter armor, etc. However, the surface of aramid fibers is relatively inert and has low reactivity, resulting in poor interfacial adhesion between aramid fibers and substrates such as resins. In order ...
