BIO-BASED CHEMICAL FIBER

Bio-based chemical fiber, born in sustainable development, growing in technology and fashion.

With natural woods as raw materials, the new eco- solvent is developed through innovation to lead the green innovation of cellulose fibers.Biomass raw materials are used to replace petrochemical raw materials to facilitate the continuous expansion of bio-based polyamide fibers, spandex and other fiber raw material systems. The post-process is crosslinked and superimposed with anti-bacteria treatment to further improve the performance and functionality of Lyocell fibers.To continuously create unlimited possibilities,and contribute the power of fiber to change nature.

Man-made cellulose filament yarn by ionic liquid method

Recommendation Reasons

The raw materials come from natural cellulose in fast-growing woods, which are naturally degradable and the filament yarn possesses excellent fiber performance. The solvent can be recovered and reused.The entire production system forms a closed-loop recovery and recycling system. Lt realizes green upgrading, becoming a new concept of green fiber.

Processing Technology

The latest generation of green solvent-ionic liquid is used to dissolve natural cellulose into spinning gel, and the physical method of man-made spinning process is used to produce man-made cellulose fiber by ionic liquid method.

Q: What are the outstanding advantages of the ionic liquid production process

in terms of environmental protection?

A: The whole production process of the man-made cellulose fiber by ionic liquid method is free of dangerous chemicals such as sulfuric acid and carbon disulfide, without HzS and CS₂ gas discharge. The ionic liquid used in the process can be recycled after recovery and refining. The whole production process forms a closed-loop recovery and recycling system, which is green and environmentally friendly.
