摘　　要：对PTT/毛混纺织物与PET/毛混纺织物进行弹性测试。通过对比分析发现,与同组织的PET/毛混纺织物相比,PTT/毛混纺织物断裂强力较低,而断裂伸长较大,缓折痕回复性较好,在整个拉伸过程中表现出低模量的特征;PTT/毛混纺织物的弹性伸长和弹性回复能力大,对人体收紧力适中,应力松弛小。The elasticity of the PTT/wool blend fabric and the PET/wool blend fabric are tested,and their difference is analyzed.It is found out that the PTT/wool blend fabric possesses lower strength and higher elongation at rupture and the modulus of the PTT/wool fabric is lower during the whole stretching comparing to the PET/wool blend fabric of the similar weave structure.The elongation recovery ratio of the PTT/wool fabric is higher than the PET/wool fabric.The PTT/wool fabric performs a lower stress relaxation and crease recovery than the PET/wool fabric.
