Abstract: An elastic waterproof fabric includes an elastic cloth layer, an ethyl carbamate layer, and a polytetrafluoroethylene layer sandwiched between the polyurethane ethyl carbamate layer and the elastic cloth layer. The elastic cloth layer is composed of main yarn and an elastic yarn. The elastic yarn is selectively composed of spandex or polytrimethylene terephthalate PTT+polyethylene terephthalate PET or polybutylene terephthalate PBT+polyethylene terephthalate PET or polypropylene terephthalate+cationic dyeable polybutylene terephthalate.

Abstract: Provided is a composite twist color fiber formed by joining polypropylene terephthalate (PPT) and cationic-dyeable polymer side by side. The polypropylene terephthalate (PPT) and the cationic-dyeable polymer differ in contraction rate, such that the composite fiber thus formed is not only helical but also extensible and contractile. Fabric made of the composite fiber is highly capable of elongating and retracting; hence, not only do finished products made of the fabric have low contraction rate, but surface of the fabric also exhibits satisfactory mixing tones.

Abstract: A medical protective clothing fabric includes a Teflon fabric and a petrochemical synthetic filament fabric bonded to the Teflon fabric, where the Teflon fabric and petrochemical synthetic filament fabric are heated and bonded together with high frequency and high pressure, and the fabric hole density of the Teflon fabric is 0.05 ?m to 0.1 ?m. Whereby, the infectious substances can be prevented from penetrating through the Teflon fabric, and since the Teflon fabric has high temperature resistance, it is not easy to melt, deform or break in a high temperature environment. With the bonding processed with high frequency and high pressure, the processing is simple, the processing cost is significantly reduced, pinholes can further be prevented from being produced, and infectious substance is prevented from penetrating through pinholes. Furthermore, the petrochemical synthetic filament fabric improving wearing comfort allows the medical protective clothing fabric to be waterproof and air permeable.
