摘要: 目前服装丝织产品质检中常出现缝口纰裂而影响其美观性和耐用性,为了解决该问题,首先选取13种薄型丝织物作为研究对象,根据薄型丝织物物理力学性能的测试结果,运用聚类分析将其分为3类。再采用L16(44×23)混合水平正交表,通过测试在不同缝纫条件下薄型丝织物缝口拉伸的纬向滑移量,分析并探讨各缝纫条件对缝口纰裂的影响。研究结果表明:线迹密度对缝口纰裂的影响最大,缝型对于缝口纰裂的影响较大,缝纫线种类对于缝口纰裂的影响较小,机针对于缝口纰裂的影响不显著。

Abstract: At present, stitch slipping always appears to affect aesthetics and durability of silk garments in quality control. In order to solve it, firstly, 13 kinds of thin silk fabrics were selected as the research object and divided into three categories by cluster analysis, according to the test results of the physical and mechanical properties of thin silk fabric. Secondly, L16 (44×23) mixed orthogonal array was applied to test the weft slippage of seam stretch of thin silk fabric under different sewing conditions, and the influence of each sewing condition on stitch slipping was discussed. The result indicates that, the order of influence on stitch slipping of thin silk fabric is as follows: stitch density>seam type> sewing thread> the size of sewing needle.
Key words: thin silk fabric; stitch slipping; sewing conditions; fabric classification; weft slippage
縫口纰裂作为丝织服装出厂时需检验的重要性能之一,直接影响了服装的美观性和耐用性,而纰裂问题一直存在,其中薄型面料尤其是丝绸面料纰裂现象更为突出[1]。一般情况下,织物经纱更易沿着纬纱方向发生滑移,即纬向纰裂或称为经纱纰裂。目前国内外在缝口纰裂方面的研究,主要包括纤维种类与性能、织物结构、织造工艺与后整理,以及织物在使用过程中的受力情况等[23]。经文献查阅,面料性能、缝纫条件对缝口纰裂有一定的影响[45]。在面料性能方面,剪切刚度、摩擦力、弯曲刚度等性能对缝口纰裂也有一定的影响[3],如弯曲刚度越大的织物,纱线更容易发生滑移。在缝纫条件方面,不同线迹密度、缝纫线、机针及缝型等缝纫条件对缝口纰裂有不同的影响[67]。结果表……
