Problems solved by technology

But the deep dyeing effect of this fiber is poor, especially when it is dyed black, the polarization phenomenon is serious, and adding dyes will not help it. The larger the dye ratio is, the more serious the polarization will be, and the fabric produced with this fiber will feel hard after dyeing
It is precisely because of these two major defects that seriously restrict the development and marketing of Paxter fiber downstream products

Abstract

The invention discloses a cationic chromophilous copolyester fibre dyeing assistant and a dyeing method using same. The copolyester fibre assistant comprises the following components by mass percentage: 45-57% of polyol benzoate, 35-45% of polyol, 4-10% of nonionic surfactant and 4-10% of cationic surfactant. The cationic dye chromophilous copolyester fibre dyeing assistant in the invention is a green and environment-friendly assistant, and has no odor and toxicity as well as low COD. The assistant can help the cationic chromophilous copolyester fibre to realize dyeing at a low temperature, the dyeing temperature can be lowered to 60 DEG C, and the dyeing effect is as good as that at the temperature of 98-100 DEG C, thus greatly lowering energy consumption.

Description

technical field [0001] The invention relates to a fiber dyeing aid and a dyeing method thereof, in particular to a cationic dye easy-to-dye copolyester fiber dyeing aid and a dyeing method thereof. Background technique [0002] Since the advent of chemical fibers, synthetic fibers, especially polyester fibers, have developed rapidly. The output of polyester fibers in my country ranks first in the world, and it is the textile fiber with the largest domestic production and consumption. With the advancement of industrial technology, people's demand for textile fibers has become wider and higher, and the required performance has become higher and higher. Countries have begun to develop a large number of differentiated fiber materials, and the proportion of differentiated fibers in synthetic fibers has increased rapidly. . Judging from the research and development of various countries, polyester fibers account for the largest proportion of differentiated fibers. [0003] Polyes...
