摘　　要：为了解PTT/PET三维卷曲复合丝及其不同织物参数对织物拉伸性能的影响,通过改变PTT/PET复合丝比例、捻度、织物组织和纬密4个参数织造了33种织物,测试并分析了这些织物的拉伸性能指标。研究发现:PTT/PET双组分长丝织物拉伸断裂强力较低,而断裂伸长较高,低负荷条件下织物具有高伸长特性;在相同的条件下,随着纬纱PTT/PET含量提高,断裂强力呈下降趋势而断裂伸长相应提高,纬密主要影响织物的拉伸断裂强力,对断裂伸长的影响不大,PTT/PET复合丝的捻度对低负荷条件下织物拉伸性能影响明显,因织物组织不同其拉伸性能也存在一定差异。In order to acquire an understanding of the effect of 3-D crimped PTT/PET component yarn and fabric parameters on the tensile strength of the fabric. 33 types of fabrics were woven by varying the proportion of PTT/PET bi-component filament, twists, density and textile weave, and the tensile strength of these fabrics was tested. It was found that FIT/PET bi-component filament fabrics have high breaking elongation but low tensile strength, and exhibit high elongation under low load. Under the same condition, increasing the content of PTT/PET filament in the weft decreases the tensile strength but increases the breaking elongation. Weft density mainly affects the tensile strength orther than breaking elongation. The twist of PTT/PET filament has significant effect on the tensile property of the fabric under low load, but it varies with textile weave.
