High-moisture-penetrability waterproof fabric

Abstract

The invention discloses a high-moisture-penetrability waterproof fabric which comprises basic cloth and a coating layer positioned on one side of the basic cloth, wherein a second priming coating is obtained by drying slurry consisting of the following components by weight percent: 100 percent of polyurethane resin, 38-42 percent of bromoethane, 19-21 percent of antimonous oxide, 4.5-5.5 percent of zinc borate, 4-5 of a bridging agent, 1.6-2 percent of a promoting agent, 1.4-1.6 percent of an anti-washing agent and 9-11 percent of phosphate antiflaming fuel; a surface coating is obtained by drying slurry consisting of the following components in percent by weight: 100 percent of polyurethane resin, 9-11 percent of bromoethane, 4.5-5.5 percent of antimonous oxide and 0.9-1.1 percent of zinc borate; antiflaming acrylic yarns consist of the following components in percent by weight: 4 percent of acrylic, 3.5-4.5 percent of cotton and 0.9-1.1 percent of aramid fibers; the bridging agent is isocyanic acid ester; the promoting agent is an organic ammonia salt; the anti-washing agent is trimethylolpropane poly-material. The high-moisture-penetrability waterproof fabric is long in antiflaming time, small in smoke generation amount, and good in antiflaming effect and has the washing-resistant effect, and the hydrolysis of antiflaming substances is avoided.

Description

technical field [0001] The invention relates to a waterproof fabric with high moisture permeability, which belongs to the technical field of textile fabrics. Background technique [0002] At present, coated fabrics only have a single function, which cannot satisfy the long-term operation of the human body in relatively harsh environments (high humidity, poor air circulation, such as mining industry and oil well operators), which is not conducive to special types of work (traffic police, patrol police, road cleaning personnel) ) In the daily operation process, due to the insufficient visibility of the fabric, it is impossible to protect and protect the safety of the human body, which is not conducive to the implementation of special circumstances (such as fire fighting, accidental explosion, and burning). The fabric only has combustion-supporting properties, which will cause burns and burns to the human body. Contents of the invention [0003] The purpose of the present in...

Problems solved by technology

[0003] The purpose of the present invention is to provide a long-lasting flame-retardant coating fabric with safety protection performance and its manufacturing process, which overcomes the poor flame-retardant effect of the prior art, the flame-retardant effect is not long-lasting, the amount of smoke is large, and molten droplets are easily generated , the flame retardant effect is not resistant to washing, the flame retardant substance is easy to hydrolyze, the fabric is easy to lose water pressure after folding, the heat resistance of polyurethane resin is not good, and the hydrolysis resistance is not good
