Polypropylene, as a new environmental protection material. Due to its light weight, moisture absorption, environmental protection, and good resistance to acid and alkali, the fine denier polypropylene has attracted more and more attention and application in the clothing industry. As we all know, clothing has a high demand for the color of the fabric. But because of the high crystallinity of polypropylene, the non-polar group in the molecular chain, low hydrophilicity, difficult to dye.

At present, the dyeing of polypropylene is divided into two kinds: one is to use the color mother grain directly in the spinning process to form, want what color, use what color mother grain; The second is to add the dye to the spinning process, and then the white silk woven rug or other fabric can be dyed naturally.
