摘　　要：选取3种不同的聚对苯二甲酸丙二醇酯/聚对苯二甲酸乙二醇酯(PTT/PET)双组分自卷曲丝织物,研究其力学性能及织物风格之间的差异.采用KES-F系列织物风格仪测试了织物的弯曲、剪切、拉伸、压缩及表面性能等16项力学性能指标,并采用川端方程计算织物风格和综合风格值.研究结果表明:研究对象较适合做轻薄的冬季西服面料;单丝线密度和染整失重率对织物的弯曲刚度和剪切刚度有较大的影响;PTT/PET自卷曲丝的结构是影响织物的拉伸和剪切性能的重要因素.The mechanical properties and hand values of three fabrics made of different polytrimethylene terephthalate/polyethylene terephthalate （PTT/PET） bi-component self-crimping filaments are measured and compared.The 16 mechanical properties of fabrics are tested by the KES-F （Kawabata evaluation system fabric） machine,including the bending,shear,tensile,compression and surface properties,et al.The hand values and total hand values are calculated by Kawabata formula.The research results show that the PTT/PET bi-component fabric is more suitable for lightweight winter suit.The bending rigidity and shear rigidity are greatly influenced by the linear density per filament of fabric and dyeing weight loss rate.Tensile and shear properties of fabric are affected by the PTT/PET bi-component filament structure.
