Contribution of fibre profile to performance characteristics of polyester-viscose and polyester-cotton ring and MJS yarns

Abstract

The influence of fibre cross-sectional shape and production speed on the performance potential of polyester-viscose and polyester-cotton ring- and MJS yarns has been studied. The data indicate significant differences in the performance of the yarns produced with different spinning speeds and the yarns spun with high spinning speed display better structural intrigrity, high compressional resilience, low compressional energy, high abrasion resistance and more hairiness than the yarns spun under identical condition but with lower speed. Incorporating non-circular fibre in the mix greatly reduces structural integrity, abrasion resistance and hairiness for both yarn structures. The reduction in their characteristics is highly dependent on the fibre mix and production speed. For all experimental combinations, the MJS yarns possess better structural integrity, better compressional resilience, less hairiness and lower abrasion resistance than the ring - spun yarns.
