Socks, which are a necessary item of clothing, need to be comfortable, affordable, and retain their quality throughout their life. Dimensional stability is one of the basic requirements of socks. The purpose of this study is to investigate the contributing factors, that is, elastane percentage, main yarn material, and process type on dimensional stability of socks. Four different percentages of elastane in plaiting yarn (4%, 6%, 8%, and 10%), two main yarns materials (100% cotton and polyester/cotton 52/48), and two process types (wash and bleach) were taken as level of input variables to study the effect on dimensional stability of socks using full-factorial experimental design method. Statistical tool (analysis of variance) was used to check the significant effect of different factors. It was found that with the increase in elastane percentage, shrinkage was decreased. Cotton was found to have more shrinkage percentage as compared to polyester/cotton. In addition, it was observed that washing treatment produced significantly lesser shrinkage than bleaching. These data present a great interest to sock manufacturers who can make better choices to manufacture, dimensionally stable socks.

影响袜子尺寸稳定性因素的全因子实验设计方法

袜子是必不可少的服装，需要舒适、负担得起，并在其一生中保持其质量。尺寸稳定性是袜子的基本要求之一。本研究的目的是调查影响袜子尺寸稳定性的因素，即弹性纤维百分比、主纱材料和工艺类型。编织纱线中弹性纤维的四种不同百分比（4%、6%、8% 和 10%）、两种主要纱线材料（100% 棉和涤纶/棉 52/48）和两种工艺类型（水洗和漂白）分别为作为输入变量的水平，使用全因子实验设计方法研究对袜子尺寸稳定性的影响。使用统计工具（方差分析）检查不同因素的显着影响。结果表明，随着弹性纤维含量的增加，收缩率有所下降。与聚酯/棉相比，棉被发现具有更高的收缩率。此外，观察到洗涤处理产生的收缩明显小于漂白。这些数据引起了袜子制造商的极大兴趣，他们可以做出更好的选择来制造尺寸稳定的袜子。
