Quick Answer: What is CDP yarn?

What is CDP fabric?

Cationic dyeable polyester(CDP) was produced through melt blending of cationic chips having of sodium salt of dimethyl ester of 5-sulfoisophthalic acid(DMS salt) and normal polyester chips in different proportions to obtain yarns having varying amount of comonomer in the fiber.

What is CDP polyester?

Cationic Dyeable Polyester (CDP) is a special modified polyester fiber which is charged with anionic groups during polymerization. Having anionic groups, it can be dyed with cationic dyes giving good results with high brilliancy.

What does cationic Yarn mean?

What is cationic dye?

Cationic dyes are dyes that can be dissociated into positively charged ions in aqueous solution. They can interact with the negative groups on the fiber molecules to form salts, which can be further firmly attached to the fibers, thereby staining the fibers.

What are basic dyes?

Basic dyes are water-soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Usually acetic acid is added to the dye bath to help the uptake of the dye onto the fiber. Basic dyes are also used in the coloration of paper.
