https://www.nylonhscc.com/products/nylon-6/ At present, green and environment-friendly fabric product is still a popular development trend. Environment-friendly color-spun nylon 6 fiber is made of spinning raw materials with colorant (such as masterbatch). The advantages of the fiber are high color fastness, bright color, uniform dyeing and so on. Because the colorant is environment-friendly and non-toxic and the grey fabric does not need to be put into the dyeing vat for dyeing, the waste water is greatly reduced. Therefore, its production process is environmentally friendly.
