High moisture permeability waterproof fabric

Abstract

The invention discloses a highly moisture-permeable waterproof fabric, which includes a base fabric and a coating layer located on one side of the base fabric. The second base coating layer is obtained by drying a slurry composed of the following mass proportion components: polyurethane resin 100, Bromoethane 38~42, antimony trioxide 19~21, zinc borate 4.5~5.5, bridging agent 4~5, accelerator 1.6~2, detergent resistance 1.4~1.6, phosphate ester retardant oil 9~11 ; The top coating is obtained by drying a slurry composed of the following mass proportion components: polyurethane resin 100; ethyl bromide 9~11; antimony trioxide 4.5~5.5; zinc borate 0.9~1.1; the flame-retardant acrylic yarn It is composed of components with the following mass proportions: acrylic: cotton: aramid = 4: 3.5~4.5: 0.9~1.1; the bridging agent isocyanate; the accelerator is an organic ammonium salt; the resistant The detergent is trimethylolpropane isopolymer material. The highly moisture-permeable waterproof fabric of the present invention has a long flame-retardant time, a small amount of smoke, and the flame-retardant effect is resistant to washing, thus avoiding the hydrolysis of flame-retardant substances.

Description

Technical field [0001] The invention relates to a highly moisture-permeable waterproof fabric and belongs to the technical field of textile fabrics. Background technique [0002] At present, coated fabrics only have a single function, which cannot simultaneously meet the requirements of long-term operation of the human body in relatively harsh environments (high humidity, poor air circulation, such as mining industry, oil well operators), and 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 unable to protect the human body's own safety, which is not conducive to the implementation of special circumstances (such as fire extinguishing, accidental explosions, and burning). The fabric is not flame retardant, and The fabric only has combustion-supporting properties, which may cause burning or burns to the human body. Contents of the inventi...
