1 聚對苯二甲酸乙二酯 / 氧化鎢粉體複合材料之製備與功能性研究 A Study on Fabrication and Functional Properties of PET Composites with Tungsten Suboxides Powders 1 (40%) *1, 2 (30%) 2 (10%) 2 (10%) 2 (10%) Sheng-Jie Wang 1, Kou-Bin Cheng *1, 2, Jing-Tang Chang 2, Jen-Yung Liu 2, Fu-Liang Huang 2, Mei-Hei Lee 3 Department of Fiber and Composite Materials, Feng Chia University 1 Textile and Material Industrial Research Center TMIRC, Feng Chia University 2 摘要 Zhanyi Science and Technology Ltd Company 3 WOx PETWOx JP Alambeta 10 1 wt% nm Zeta mv WOx Abstract This study includes three stages. First, the dispersion of WOx powders in ethylene glycol slurry with different solid content which is prepared by applying sonicator and ball milling processes were compared. In order to drawn fiber in right proportion, the particle size and Zeta potential of WOx powder in different refined processes was investigated. The second part of this study was to synthesize PET/WOx composite, fiber and yarns. The chemical structure and thermal properties of composite yarns. The surface morphologies and compositions of composites were observed and characterized by applying SEM with EDS. The third part of this study was to weave fabrics by applying such PET/WOx composite yarns with different weft density. The heat shedding rate of woven fabrics was tested by JP test standard. Furthermore, the thermal properties of fabrics were measured by Alambeta tester. The WOx powder which is sonication treated for 10 minute exhibits a finest particle size of nm, and lowest zeta potential of mv. It is also well dispersed in subsequently synthesized polyester yarn. It found that these composite fabrics shows a heat shedding property. It could be used in heat shedding textiles, in the future such as home textiles, traffic textiles, military textile and sports textiles etc applications. 關鍵字 : 聚酯氧化鎢隔熱 Keywords: Polyester, Tungsten Suboxides (WOx), Heat Shielding A-05 一前言 2014
