Bulk characteristics of air-jet textured yarn woven fabrics

Abstract

Fabric thickness and specific volume in relation to the nature of weft threads (air-jet textured yarn or flat yarn), pressure level during thickness measurement, pick density and heat setting have been analyzed. On heat setting, the fabric thickness and specific volume increase appreciably for the textured yarn fabrics. The changes in fabric thickness with the increase in pick density of textured and flat yarn fabrics are dependent on the pressure level applied during thickness measurement. Increase in pick density, in general, leads to decrease in

fabric specific volume. Fabric specific volume derived from the thickness measured at 5 gf/cm²<i> </i>pressure should be used for assessing air-jet textured yarn bulk.
