WATERPROOF FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a lightweight waterproof fabric having a flexible feeling and excellent in hydrolysis resistance, surface strength and tear/tensile strength. SOLUTION: A first layer comprising a reaction type polyurethane resin having a polyether bond compounded with a crosslinking agent is formed on at least the single surface of a long fiber fabric and a second layer comprising a one-pack type polyturethane resin having a polyether bond is subsequently formed on the first layer in an amt. of 220 g/m2 or less. Further, the long fiber fabric is pretreated with a fluorine type water repelling agent.
