Embodiment Construction

[0021] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0022] As the manufacturing method of the impact-resistant soft non-weft fabric of an embodiment of the present case, the method comprises the following steps:

[0023] Step 1) Dip the uniformly laid fiber filaments into the glue tank containing the adhesive, lay the dipped fiber filaments on the surface of the release material, and send the fiber filaments compounded with the release material to the coil The system is drawn into the drying equipment for drying, and then rolled to obtain a rolled single-fiber layer containing glue;

[0024] Step 2) Take two rolls of adhesive single-fiber layers, peel off the release material of the adhesive single-fiber layers, heat-compress the stripped two rolls of adhesive single-fiber layers at a relative angle of 45-90°, and collect Roll, obtain double-layer composite fiber layer; ...

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...
