Development of High Value-added Vortex Yarns and Fabrics with Enhanced Flame-resistance and Comfort

This project aims at developing meta-aramid/flame-resistant (FR) viscose fibre blended fabrics for flame-resistance clothing with enhanced flame-resistance, comfort and pilling performance using a cost-effective mid-length fibre vortex yarn technology and specially-designed fabric structure.

First, advanced mid-length fibre vortex spinning technology will be applied for producing aramid/FR viscose vortex yarns with very low hairiness and improved strength. Secondly, spinning trials will be conducted to study influences of fibre proportion and spinning parameters. Furthermore, based on the specially-designed fabric structure, weaving trials will be conducted for producing aramid/FR viscose blended vortex woven fabrics with enhanced flame-resistance, comfort and pilling performance. A statistical model will be established for predicting the relationship between aramid/FR viscose blended ratio of vortex yarn and the resultant fabric flame-resistance and thus for maximising the blending effect of fibres as well as minimising the fibre cost.
