Abstract
In this study, the tensile properties and water repellency of heat-treated thermoplastic polyurethane (TPU) composite fabric were investigated and compared with those of untreated TPU composite fabric. The TPU composite fabric was prepared using a TPU coated polyester filament (PET FY) with a volume ratio of 33%:67% (PET FY:TPU). The properties of the TPU composite fabric were found to be affected by heat treatment to various extents depending of the temperature. A maximum tenacity of 34.5 MPa, a contact angle of 130 o (indicative of good water repellency), and an ISO grade of 5 (indicative of high resistance to surface wetting) were obtained at a heat-treating temperature of 190 oC.
