Abstract

The invention discloses a manufacturing method of anti-impact soft no-woven cloth. The method comprises the steps that 1, fiber adhesive dipping is conducted, and hot-pressing is conducted on single-fiber layers; 2, hot-pressing is conducted on two-layer composite fiber layers; 3, hot-pressing is conducted on two-layer composite fiber layers with two to four rolls to prepare the anti-impact soft no-woven cloth with four to eight composite fiber layers, wherein adhesives used in the method comprises ethylene vinyl acetate copolymers, waterborne polyurethane resin, terpene resin, polyethylene glycol, o-methoxyhydroquinone and strontium fluoride. According to the manufacturing method of the anti-impact soft no-woven cloth, the adhesives are improved, a multi-component composite formula is adopted, the bonding strength and the bonding density of the adhesives on fibers are effectively improved, and the tenacity and the anti-impact property of the no-woven cloth are improved; freezing and unfreezing are conducted on the fibers which are dipped in the adhesives, the internal stress and the surface tension of the adhesives are effectively decreased, and hot-pressed composite fiber layers have higher strength and anti-impact capacity.

Description

technical field

[0001] The invention relates to a method for manufacturing a non-weft cloth, in particular to a method for manufacturing an impact-resistant soft non-weft cloth. Background technique

[0002] With the development of national defense, aerospace, ocean operations and various civilian fields, the performance requirements of protective materials and reinforced composite materials are increasing day by day. Among them, the non-woven fabric products of a single material are difficult to meet multiple needs at the same time due to the defects of their respective materials. Such as: Aramid fiber non-weft fabric has good softness, but poor light resistance, water and chemical properties; high-strength high-modulus polyethylene fiber non-weft fabric is light in weight, high in protection ability, good in water resistance, light and chemical stability, but not resistant to high temperature, fracture The extension is large, and the back concave after the impact is large...
