  Abstract

In this study, polypropylene (PP)/titanium dioxide ( TiO2) woven fabrics are proposed and made using wrapping, yarn coating, and woven processes. First, stainless steel (SS) wrapped yarns are tested for tenacity to examine the influence of wrapping number, which verifies that the optimal wrapping number is 7 turns/cm. Then, the optimal SS wrapped yarns are coated with PP/TiO2 melts, after which the resulted PP/TiO2-coated yarns with optimal mechanical properties are made into woven fabrics. The mechanical properties, UV transmittance, and electromagnetic shielding effectiveness (EMSE) and PP/ TiO2 woven fabrics are evaluated, thereby examining the influences of the content of TiO2 of and the coiling speed. The test results suggest that increasing TiO2 adversely affects the mechanical properties of PP/TiO2-coated yarns and woven fabrics. UVB causes severe damage to the skin and PP/TiO2 woven fabrics can decrease UVB transmittance to 8.14%. Moreover, PP/TiO2 woven fabrics at lamination angles of 0°/45°/90° have the optimal EMSE of -38 dB. To sum up, to incorporate PP/TiO2-coated SS wrapped yarns provides PP/TiO2 woven fabrics with UV-shielding ability and electromagnetic shielding response. The resulting functional fabrics are featured by lightweight and flexibility.
