Air Interlaced Self-Twist Yarns

Abstract

An earlier investigation revealed that commingling self-twist yarn with a thin multifilament improved yarn appearance and strength. This paper describes a continued effort in that direction. Self-twist yarns are spun and air interlaced in a continuous operation on the Repco self-twist yarn spinning machine without the introduction of filaments. The abrasion resistance of the self-twist yarn is remarkably enhanced after air interlacing, especially in the zero-twist parts. When compared with counterparts made from self-twist and STT yarns, the knitted fabrics from the air interlaced self-twist yarn show improvements in handle and most mechanical properties, along with reduced knit loop distortion, which is inherent in ordinary self-twist yarn due to its structural variation.
