Studying the Tensile Properties at the First Break of Multiple-Yarn Structure Fancy Gimp Yarns Using the Design of Experiments

ABSTRACT

This study was conducted to identify the factors and the interactions, which affect the load and elongation at the first break of gimp yarns. The experimental design had seven factors: two levels each. It was found that using two single yarns, instead of a similar ply yarn, for the core component, caused the increase of values of load and elongation at the first break. The effect component contributed positively to the load and elongation when it was a cotton yarn rather than a bamboo yarn. This study contributes to a broader understanding of process–structure–property relationships of fancy yarn.

摘要

本研究旨在探讨影响桁架纱初断伸长率及负荷的因素及其相互作用。实验设计有七个因素——两个层次。结果发现，对于芯部构件，采用两根单纱代替类似的股线时，在初断时载荷和伸长率值增加。在纯棉纱线而不是竹子纱线时，影响组分对纱线的负荷和伸长率有正向贡献，这项研究有助于更广泛地了解花式纱线的工艺-结构-性能关系。
