Cellulose is the largest renewable resource on the earth at present, has the characteristics of low price, light weight, biodegradability and the like, and is an ideal green environment-friendly material. In modern life, the use of cellulose has long been limited not only to the traditional textile garment and pulp and paper fields, but also widely used in the manufacture of various fiber reinforced composites and used in many important structures. The characteristics of high specific strength, large specific rigidity and designable material performance make the cellulose fiber reinforced composite material become one of the novel structural materials with the greatest development prospect. The cellulose filament is widely applied in the fields of knitting and silk weaving, is only used on weft on denim, has the same dyeing property with cotton fiber, and is a new subject when applied to denim warp yarn.

The cellulose filament has the characteristics of high strength, low elongation and easy slippage, and the conventional denim equipment ball warp machine is used for preparing balls (shafts) for bundle dyeing, so that the denim cannot be dyed smoothly on a rope-shaped dyeing machine. The main reason is that the ball warp machine can not realize that each yarn is wound into balls with the same length in the warping process, so that a large amount of serious loose yarns are wound on the yarn guide roller during dyeing and unwinding, and dyeing can not be smoothly carried out; furthermore, the friction and stretching of the filaments by the dyeing process may result in a loss of gloss of the filaments.
