Development of Worsted Yak Yarns and Fabrics

Yak mainly survives at high altitudes in Tibetan Plateau and Himalayan Mountains. There are over 16 million yaks in the world and 80% of them are in China. Yak hair has good features in strength, warmth, odour resistance and breathability, and particularly possesses cashmere like hand feel. However yak fibers are difficult to be made into yarn because of its short length, large dispersion of fiber length and low fiber cohesion. Therefore yak is mainly processed by woolen or semi-worsted systems for producing heavy and coarse products. Therefore this project aims at developing light, thin and high quality yak knitted fabrics. First, advanced spinning methods and apparatus will be applied and modified in order to develop a new spinning method for producing fine yak yarns. Secondly, knitting machine settings and parameters will be designed and optimized in order to make light, warm and soft yak knitted fabrics. In addition, physical and functional properties of yak will be analyzed with comparison to other animal fibers such as merino wool, cashmere and alpaca in order to facilitate the development of high quality yak fabrics and textile products. The success of this project will not only make yak to be better applied in high quality textile products, increase its added-value, enhance the competitive power of local textile industries and bring new business opportunities to them, but also improve the living standard of herders in Tibetan and some other remote communities in China.
