Improved incorporation of fibres for more abrasion resistant yarns

Abstract

Rubbing of the fibrous strand after drafting, but before twist insertion improves the incorporation of surface fibres. The method delivers the benefits of a small spinning triangle like compact spinning and improved fibre trapping like siro and solo spinning. The yarns produced are less hairy and more resistant to degradation in downstream processing. This can improve the weavability of the yarns, reduce the sizing costs and increase service life of the fabrics by making them more resistant to wear and pilling.

Key words:

• yarns
• abrasion resistance
• fibre trapping
• spinning
• rubbing
