Dope-dyed fiber is a waterless dyeing process that does not produce wastewater during the spinning process. Since solution-dyed fiber no longer requires post-dying, it is an ideal raw material for dyed yarn and meets the requirements of the development of circular economy.
The main advantages of liquid dyed fiber are: 1. Healthy fiber: inorganic mineral materials are added instead of chemical dyes. 2. Good color fastness: The pigment and fiber are closely combined and the color fastness is good. 3. Environmentally friendly: Contrast dyeing can reduce wastewater and other pollution generated by dyeing and finishing.
