摘　　要：采用新型聚酯纤维———PTT织制了4种纬弹织物,选用2种市售棉氨包芯纱织物与其对比,实测了它们的应力-应变曲线和定伸长重复拉伸性能。通过实验,将PTT织物与棉氨包芯纱织物相比,PTT织物在高伸长下仍表现出低模量的特征;PTT织物弹性回复能力高,对人体有更好的收紧作用,可起到紧身健美的效果。Four weft elastic fabrics made of a new kind of polyester (fiber?——PTT) were woven.Two fabrics made of the core-spun yarn with lycra were chosen to compare with PTT fabrics. Their stress-strain curves and repeated stretch property were measured. The following things are found out:compared with the fabrics made of lycra core-spun yarn, the modulus of PTT fabrics at high strain is lower,the elongation recovery ratio of PTT fabrics is higher than the former, PTT fabrics perform a better effect of tight fitting and bonny on body than the former.
