Yak mainly survives at high altitude in the Tibetan Plateau and the Himalayas. There are over 16 million yaks in the world and 80% of them are in China. Yak yarn possesses excellent strength, warmth and breathability. To the hand, it feels like cashmere. However, machine conversion of yak fibres into a useful yarn is challenging, particularly to obtain a fine yarn. In this project, a new spinning method and system were developed, which used a multi-level spinning triangle to produce fine worsted yak yarns with good yarn properties. The system incorporates newly-developed technical units into a conventional ring frame. The resulting yarn is a fine worsted yak yarn of high strength, low hairiness and good evenness. Knitted fabrics are thin and soft, and exhibit better air permeability and heat retention than those made with cashmere and merino wool fibres.
A non-exclusive licence covers the knowhow of the technical device production and installation of spinning machine for production of the yak yarn.
