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

ABSTRACT

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 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 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.

摘要

粗牦牛纤维仍然未充分利用由于其高刚度、低摩擦系数，和颜色深黑色。这种纤维经过化学改性，使其颜色与黄麻纤维相似。改性后，摩擦系数从未处理样品的0.280提高到0.368。摩擦与色泽协同改善提高牦牛纤维与黄麻纤维混纺的可接受性。经过适当的改性后，可以将75%牦牛纤维与黄麻混纺。黄麻/牦牛纤维混纺纱线被改为平纹织物，纬纱和涤纶纱为经纱。
