双组分复合长丝PTT/PET弹力牛仔面料的性能研究

Study on the Properties of Elastic Denim with PTT/PET Filament

双组分复合长丝PTT/PET织物是弹力面料发展的新趋势。对双组分复合长丝弹力牛仔面料的定负荷伸长、弹性回复率、悬垂性、折皱回复性、抗弯性能进行了测试与分析,并与棉/氨弹力牛仔面料、普通纯棉牛仔面料进行比较。结果表明PTT/PET弹力牛仔面料能够达到棉包氨纶牛仔面料的弹性,具有较好的弹性回复率和抗弯性,但织物悬垂性较差。

The stretch fabric with the bicomponent filament（PTT/PET） is being developed.The gabric properties that include elongation,drapability,crease resistance and bending rigidity were measured in this paper.Comparing cotton elastic denim fabrics with spandex,the results showed that the bicomponent filament PTT/PET fabrics have the same elongation as cotton/spandex elastic denim fabrics.They have also good elasticity recovery rate and anti-bending.But the bicomponent filament PTT/PET fabrics have bad drap property.
