Processing Parameter Optimization of PTFE YarnQu Lijun Zhang Mingxia Guo Xiaoqing Liu Yan Sun Yaning Qingclao UniversityAbstractrocessing optimization of PTFE yarn was studied. On the basis of single factor processing parameter test,total draft multiple, twist factor and film thickness were selected and tested by three-factors-three-level orthogonal processing test. The result shows that total draft multiple of PTFE yarn should be 1.8,twist factor should be 190 and film thickness should be 40 μm is better processing parameter.[著者文摘]
