Purpose

The aim of the present study is to consider the influence of the tensile behavior of fabric and sewing thread on the seam appearance.

Design/methodology/approach

In this study, the formation of seam puckering on two elastic and normal woven fabrics was explored. In order to prepare samples, various sewing threads were applied. Test specimens were sewn under five different thread tension levels. Then the appearance of samples was evaluated subjectively to determine their seam puckering grade before and after the laundering process.

Findings

The obtained outcomes of this study present that although sewing thread tension increment decreases the seam pucker ranking in the similar sewing condition, elastic fabrics have a greater seam pucker grade compared to the normal fabric due to the fabric extension and contraction during sewing and after sewing process, respectively. In addition, the elastic strain of the sewing thread is the key factor that determined sewing thread's tendency to make seam puckering. Moreover, the laundry process due to the relaxation of the sewing thread decreases the seam pucker grade.

Originality/value

The consistency of the tensile property of fabric and sewing thread is a crucial parameter in improving the seam appearance and obtaining a smooth seam.

缝纫线的拉伸性能和洗涤过程对弹性和普通织物接缝起皱的影响

目的

本研究的目的是考虑织物和缝纫线的拉伸性能对接缝外观的影响。

设计/方法/方法

在这项研究中，探讨了在两种弹性和常规机织织物上形成接缝褶皱的情况。为了准备样品，使用了各种缝纫线。在五种不同的线张力水平下缝制测试样品。然后主观评估样品的外观，以确定其在洗涤过程之前和之后的接缝褶皱等级。

发现

这项研究的结果表明，尽管在相似的缝制条件下，缝纫线的张力增加会降低接缝的起皱等级，但由于弹性织物在缝制过程中和缝制后的伸缩性，与普通织物相比，其接缝的起皱等级更高。 ， 分别。另外，缝纫线的弹性应变是决定缝纫线产生接缝褶皱趋势的关键因素。而且，由于缝纫线的松弛而导致的洗衣过程降低了接缝皱褶的等级。

创意/价值

织物和缝纫线的拉伸性能的一致性是改善接缝外观和获得光滑接缝的关键参数。
