摘　　要：为探究氨纶织物和PTT/PET织物在力学性能和手感风格方面的差异,采用KES-F系统测试了4组含氨纶和PTT/PET自卷曲纤维的对比织物的弯曲性能、剪切性能、拉伸性能、压缩性能和表面性能,并通过KN 301-S公式由织物的基本力学性能指标计算得到织物的手感风格指标,包括硬挺度、平展度、滑糯度、滑爽度和丰满度。测试结果表明,2类织物的力学性能和手感风格整体差异不大,但是含PTT/PET自卷曲纤维的弹力织物弯曲刚度低,触感柔软,弯曲滞后量和剪切滞后量高,造型挺括,不易悬垂。To study the difference of the hand style study and mechanical property of the fabrics that contain PTT（ polytrimethylene terephthalate） /PET（ polyethlene terephthalate） bi-component fiber and PU,KES-F system is used to test the bending,shearing,stretch,compression and surface properties of 4control groups of fabrics containing PU and PTT /PET self-crimping fibers and then calculate the hand,including the stiffness,antidrape,crispness,slippery degree and fullness by Equation KN 301-S. It is found that this two kinds of fabrics have similar hand and mechanical properties. However,the fabrics containing PTT /PET self-crimping fibers have lower bending rigidity,soft hand,higher bending and shearing hysteresis,stable shape,and antidrape.
