Multi-function woven fabric with carrier particles of PU-TiO2 coating filled in local pipes

Abstract

For preventing nano material from coming into contact with skin to generate a toxic effect, Nano TiO2 is prepared by a sol-gel method. The appearance, the crystal form and particle size of TiO2 are researched through a scanning electron microscope (SEM) , an X-ray diffraction (XRD) and other instruments. PUTiO2 coating is prepared, the coating is uniformly coated to an outer layer of semen cassiae. Local pipes are formed on weft-wise front surface and back surface of woven fabric through a special process. By taking the local pipes with good sealing performance as carriers, semen cassiae is filled in the pipes. Two-ply silver-plated polyester/cotton (65/35) yarns are used as the raw material of warp and weft of the fabric, for providing special health care and protection functions for the fabric. An average particle size of the semen cassiae is 2.54 mm by testing, and all technological parameters are calculated to obtain a best number of semen cassiae particles added at the tubular structure. By testing, the results show that the ultraviolet protection factor (UPF), the transmittance(UVA), the maximum SE, the minimum SE, the heat preservation rate, bacteriostatic rate against escherichia coli and staphylococcus aureus of the designed fabric was 48.9, 2.92%, 51.3 (dBm),32.32 (dBm), 33.2%, 92.2%, 95.3%, respectively.
