In the present study, seam failure mechanism has been investigated as a result of fabric exposure to unidirectional and multi-directional loads, considering the seam structural parameters, such as stitch type and length. To this end, three common groups of fabrics, namely worsted, shirting and dress woven, have been examined and the effect of seam properties and its interaction with fabric type is analysed through the measurement of seam’s unidirectional and multi-directional strengths and the seam efficiency. The results show that stitch type and length have a significant effect on the tensile properties of seams. Suitable selection of stitching parameters can enhance the seam performance at unidirectional and multi-directional loadings and improvement of the seam efficiency.

单向和多向载荷作用下接缝结构参数对接缝强度的影响

在本研究中，考虑到缝线类型和长度等接缝结构参数，研究了由于织物暴露于单向和多向载荷而导致的接缝失效机制。为此，研究了三类常见的织物，即精纺、衬衫和连衣裙机织面料，并通过测量接缝的单向和多向强度以及接缝效率来分析接缝性能的影响及其与织物类型的相互作用。 . 结果表明，针迹类型和长度对接缝的拉伸性能有显着影响。选择合适的缝合参数可以提高单向和多向载荷下的接缝性能，提高接缝效率。
