Abstract

The present invention introduces a process of spinning bast fibres through health preservating is as the following steps: Health preserving bast fibres; Opening and cleaning, carding the health preserved bast fibres and drawing the carded health preserved bast fibres into bast fibre strips; Health preserving said bast fibre strips; Spinning the health preserved fibre strips into yarn; the present invention also introduces a kind of yarn made by such process; The present invention further introduces a process of blended spinning bast fibre with other fibres through health preservating, and the yarn made by such process. The present invention realizes low end breakage rate, and high efficiency, so as to achieve high quality product.
