Abstract

The invention discloses a permeation type dyeing auxiliary for dyeing aramid fiber. The permeation type dyeing auxiliary comprises the following components in parts by weight: 5-12 parts of malic acid, 5-10 parts of sodium acetate, 6-11 parts of cysteine, 2-6 parts of guar gum, 10-15 parts of sodium alginate, 3-7 parts of dipropylene glycol dibenzoate, 2-4 parts of castor oil polyoxyethylene ether, 1-2 parts of a pH adjusting agent, 2-3 parts of an emulsifier and 10-15 parts of deionized water. The invention further discloses a preparation method of the permeation type dyeing auxiliary. By adopting the permeation type dyeing auxiliary for dyeing aramid fiber, the dyeing rate of aramid fiber can be effectively increased, the problem that the aramid fiber is hard to dye is solved, the dyeing effect is good, the fiber structure of aramid fiber is not damaged, and the dyed fiber is soft and comfortable, bright in color and good in gloss. The preparation method is simple and the cost is low.

Description

Technical field: [0001] The invention relates to the field of dye auxiliaries, in particular to a penetrating dye auxiliaries for aramid fiber dyeing. Background technique: [0002] At present, the most widely used new type of special fiber is aramid fiber, a high-tech fiber invented and put into production by DuPont in the 1970s. Its macromolecules are generally long chains connected by amide groups and benzene rings, endowed with a stable skeleton structure; the fiber has excellent chemical stability, thermal stability, high strength and high modulus and other characteristics. Aramid Nomex fiber has a compact macromolecular structure, high crystallinity, high glass flower temperature, and no affinity group. Aramid fiber is dyed by conventional dyeing methods, and the dye is basically not dyed, so dyeing is very difficult. [0003] At present, the following two methods are mainly used to dye aramid fibers: one is to add dyes during spinning to directly produce excellent fi...
