Physico-chemical properties of black yak fibre and its modification for blending with jute fibre

Blog Article

Coarse yak fibre remained underutilized due to its higher stiffness, lower co-efficient of friction, and deep black in color.Such fibre was chemically modified to change its color similar Fish to jute fibre.After modification the co-efficient of friction improved to 0.368 from 0.280 in the untreated sample.

The improvement in co-efficient of friction and color increased Rolling Pin the acceptability of blending of yak fibre with jute fibre.It was possible to blend 75% yak fibre with jute after suitable modification.Jute/yak fibres blended yarns were converted into plain woven fabrics as weft and polyester spun yarn as a warp.
