Polyurethane-coated Fabric for RF Welding

RF 접합용 폴리우레탄 코팅 직물

Radio-frequency(RF) weldable polyurethane-coated fabric was prepared by knife coating of presetted and cire-finished nylon fabric using optimized coating formulation including RF-sensitive commercial polyurethane resins. The physical properties, adhesion strength, peeling strength, abrasion strength, flexibility, and hydrostatic water resistance of the prepared coated fabric were good enough to show no significant difference with regular coating. Additionally the prepared coated fabric had silky and soft touch without tackiness.
