Technical Field

The invention relates to the technical field of nylon dyeing, in particular to a nylon wool top dyeing process capable of improving the running condition of nylon spinning.

Background

Nylon dyeing is generally dyed by acid or metal complex dyes, color fixation is required for achieving certain color fastness after dyeing, a leather roller is easily stained in the spinning process after dyeing, more dust is generated, and difficulty is brought to the spinning process.

Most chemical fibers have low moisture regain, low dielectric constant and high friction coefficient, and generate static electricity due to constant friction in the spinning process, and an antistatic agent and a bulking agent (having certain affinity to the fibers) are used to prevent or eliminate static electricity accumulation, and meanwhile, the fibers have the characteristics of softness, smoothness and the like, and have an antibacterial finishing effect so as to smoothly pass through the subsequent process.

The nylon fiber is formed by polymerization reaction of dicarboxylic acid and diamine, free amino and carboxyl are contained in fiber molecules, so that the nylon fiber can be dyed by acid dye, neutral dye and metal complex dye, the dye is mainly combined with the fiber through acting forces such as intermolecular force, coulomb force, hydrogen bond and the like, and firm covalent bonds are not formed between the dye and the fiber, so that the fastness after dyeing is poor. Meanwhile, due to low moisture regain, friction is constantly generated in the spinning process to generate static electricity, so that nylon fibers are easily adhered to the leather roller to generate a large amount of dust, the running condition is poor, and the production efficiency is low.

Therefore, the nylon wool top dyeing process capable of improving the running condition of nylon spinning is provided.
