Bulk characteristics of air-jet textured yarn knitted fabrics

摘要

The thickness and specific volume of knitted fabric have been analyzed in relation to yarn type (air-jet textured/flat), stitch length and relaxation treatments. It is observed that the behaviour of parent yarn fabric is very different from that of the textured yarn fabric in dry-and fully-relaxed states. The thickness of air-jet textured yarn knitted fabric is independent of stitch length in fully - relaxed state, whereas the specific volume of the fabric increases with the increase in stitch length. The specific volume of the fabric of similar stitch length or the thickness of the fabric produced from the yarn of same linear density for loosely knitted structures with tightness factor less than 10.4 can be used for the evaluation of textured yarn bulk.
