Fiber Spinning Before Coloring Industry
Fiber pre-spinning coloring refers to the addition of pigments or dyes to fiber raw materials during the fiber manufacturing process to make the fiber obtain the desired color during the textile process. The main purpose of dyeing before spinning is to improve the dyeing uniformity and color fastness of the fiber and reduce the time and energy consumption of the subsequent dyeing process.
* Fiber coloring before spinning can be applied to various fiber raw materials, such as cotton, polyester, nylon, etc. The common dyeing methods before spinning include solution dyeing, emulsion dyeing and blended dyeing. The development of fiber pre-spinning coloring technology not only improves the effect and efficiency of fiber dyeing, but also plays a positive role in promoting environmental protection and sustainable development.
