Abstract

The invention discloses a dyeing promoter of an acrylic fiber cationic dye. The dyeing promoter consists of benzoic alcohol, butyl acetate, a compound emulsifier and water, wherein the volume ratio of the benzoic alcohol to the butyl acetate to the compound emulsifier to the water is 10:10:1-2:78-79. The dyeing promoter of the acrylic fiber cationic dye can improve the dye-uptake of the lower temperature dyeing of the acrylic fibers with the cationic dye, and ensures high color fastness of dyed textile and small strength loss of fibers.

Description

technical field [0001] The present invention relates to the preparation technology of a low-temperature dyeing accelerator for acrylic fiber whose main component is a mixture of alcohols and organic esters and the low-temperature dyeing technology for acrylic fiber realized by using the accelerator, in particular to a dyeing accelerator for acrylic fiber cationic dyes and its application. Background technique [0002] Acrylic fiber is the trade name of polyacrylonitrile fiber in my country, and it is called "Olon", "Acrylon", "Cashmiron" and so on abroad. It usually refers to the synthetic fiber prepared by wet spinning or dry spinning with more than 85% of the copolymer of acrylonitrile and the second and third monomers. Acrylic fiber has the advantages of excellent softness, warmth retention, light resistance and radiation resistance. It looks like wool. It is called "artificial wool". In actual production, acrylic fibers are often blended with wool, which complement eac...
