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.
