Abstract

Rib-knit fabrics are among the fundamental structures which can be produced on the double-bed knitting machine. Ribs are very popular textiles because of certain crucial properties, i.e. extensive shrinkage in width and dimensional stability of the structure, which are not observed in the single jersey fabrics. In this study, an analysis of the physical and the mechanical properties of balanced rib-knitted fabrics has been presented. The loop structure and dimensions were also quantified. To explain the properties of rib-knitted fabrics, we have proposed and employed the phenomenon of curling. In rib-knitted fabrics, curling happens in the local regions of the fabric. Higher rib structures exhibited greater curling tendencies. Consequently, a novel method of quantification of the curling in ribs was proposed, i.e. the concept of ‘de-curling energy’. This proposed notion of de-curling energy was found to be applicable to all fabric designs. The experimental results were found to be coherent with the proposed theory.

摘要

罗纹针织面料是可以在双层针织机上生产的基本结构之一。肋是非常受欢迎的纺织品，因为它们具有某些关键特性，即结构的宽度和尺寸稳定性的广泛收缩，而在单面针织面料中则没有观察到。在这项研究中，对平衡罗纹针织面料的物理和机械性能进行了分析。还定量了环的结构和尺寸。为了解释罗纹针织面料的性能，我们提出并采用了卷曲现象。在罗纹针织的织物中，卷曲发生在织物的局部区域。较高的肋骨结构表现出较大的卷曲趋势。因此，提出了一种量化肋骨卷曲的新方法，即 “去卷曲能量”的概念。发现所提出的卷曲能量的概念适用于所有织物设计。实验结果被发现与所提出的理论是一致的。
