Effects of weave density, yarn twist and yarn count on fabric handle of polyester woven fabrics by objective evaluation method

Abstract

Systematic research works were carried out to clarify the effects of weave density, yarn twist, and yarn count on fabric handle of polyester fabrics made for the purpose, and quantitative influence was clearly shown. “Kosh” and “hari” increase with weft yarn density and “shinayakasa” and “shari” decrease with the density. The effect of the density on “fukurami” and “kishimi” is small. The effect of yarn twist is revealed remarkably on dechine and yoryu. “Koshi” and “hari” decrease and “shinayakasa” and “shari” increase with the twist in the case of dechine; however, all the primary handles increase a little with the twist for yoryu. “Kishimi” of yoryu increases greatly with the twist. “Koshi” and “hari” increase and “shinayakasa” decreases with yarn count for taffeta and georgette. The effect of the count on “fukurami” and “kishimi” is small for both fabrics. These results could provide useful information to design ideal fabrics having desirable handle.
