【摘要】 为了解新型聚酯纤维PTT(聚对苯二甲酸丙二醇酯)经编弹力泳装面料的弹性,用PTT纤维织制的经编弹力泳装面料,与锦纶(PA)和涤纶(PET)织制的经编弹力泳装面料进行对比研究.实测了它们15N和5次及25N和9次定负荷的拉伸性能,比较了它们的弹性回复率、塑性变形率和拉伸弹性伸长率;为进一步寻找3种面料的弹性回复率变化规律,列出了它们弹性回复率的回归方程式.结果显示,PTT经编弹力泳装面料断裂强力较小、伸长率较大,具有优异的弹力回复性,是制作泳装的理想面料.更多还原

【Abstract】 In order to reveal elasticity of warp-knitted swimsuit fabric made of a new kind of polyester — PTT fiber,comparison of elasticity between PTT and PA,PET warp-knitted elastic swimsuit fabrics was made.Their 3N/cm,5 times and 5N/cm,9 times fixed-load tensile property were measured,the elastic recovery ratio,plastic deformation ratio and tensile elastic elongation under the condition of fixed-load repeated stretches were compared;in order to search for the three fabric elastic recovery ratio of change,their regression equations of elastic recovery ratio were written.The results showed that PTT warp-knitted swimsuit fabric has smaller breaking strength,larger elongation,excellent resilience,is ideal for the production of swimsuit fabrics.更多还原
