Air-Jet Yarn Structure and Mechanical Properties
topic
Air-jet yarn consists of a bundle of parallel core fibres contributing 70 to 80 percent of total fibre mass surrounded by helically wrapped surface fibres providing structural integrity, with yarn tenacity of 60 to 80 percent of equivalent ring yarn due to the low core fibre contribution to load bearing, but superior abrasion resistance and pilling resistance from the tightly bound surface fibre wrapping layer.
Role
Defines the mechanical property trade-offs of air-jet yarn relative to ring and rotor yarn that govern its end-use suitability, with the lower tenacity limiting fine count application but the superior pilling and abrasion resistance positioning air-jet yarn advantageously in easy-care shirting and knitwear where surface durability and minimal hairiness are primary performance requirements.
