摘　　要：为了解氨纶丝预牵伸倍数对弹力织物性能的影响,在一定的工艺设备与条件下,纺制了不同牵伸倍数的环锭弹力纱及转杯弹力纱,利用这些弹力纱作为纬纱,分别织制了环锭弹力纱织物和转杯弹力纱织物。为了进行对比,还织造了相同规格的纯棉织物。经织物性能测试表明:弹力织物除断裂强度比纯棉织物低外,断裂伸长率、弹性回复率、折皱回复率、透气性能均优于纯棉织物;环锭弹力纱织物除折皱回复性比转杯弹力纱织物低之外,断裂强力、断裂伸长率、弹性回复性、透气性能指标均优于后者;弹力织物除透气性外,断裂强度、断裂伸长率、弹性回复、折皱回复都随弹力丝预牵伸倍数的增大先增大后减小。To know the effect of polyurethane filament draft ratio on elastic fabric performance, elastic yarns with different draft ratios were spun by rotor - spinning and ring - spinning and then fabrics were woven by using the elastic yarns as weft. To compare with the elastic fabrics, same specifications of pure cotton fabrics were woven. The tested fabrics show that the properties of elastic fabric including breaking elongation, elastic recovery, crease recovery, and fabric permeability are better than that of pure cotton fabric except breaking tenacity; the properties of ring - spun elastic fabric including the breaking tenacity, breaking elongation, elastic recovery and fabric permeability are better than that of rotor - spun elastic fabric except the crease recovery; the breaking tenacity, breaking elongation, elastic recovery and crease recovery of elastic fabric increase first and then decrease as the draft ratio increases, while the variation of fabric permeability is insignificant.
