Dyeing agent for nylon fabric

Abstract

The invention discloses a dyeing agent for a nylon fabric. The dyeing agent is prepared from the following raw materials in parts by weight: 2-8 parts of aluminium oxide powder, 10-13 parts of mica powder, 20-30 parts of butyl methacrylate, 10-20 parts of tert-butyl peroxybenzoate, 30-40 parts of dibutyl phthalate, 20-30 parts of magnesium sulfate, 20-30 parts of zinc stearate, 40-50 parts of blocked isocyanates, 5-10 parts of titanium dioxide, 10-30 parts of dinitroso pentamethylene tetramine, 10-20 parts of polyurethane, 20-25 parts of ferric oxide, 10-15 parts of initiating agent, 7-20 parts of additive and 20-40 parts of water. After the nylon fabric is dyed by the dyeing agent, the soaping fastness is 4.5-5.0 level, the dyeing is not easily cleaned, the bonding is firm, the K / S value is up to 8.168 and the dyeing performance is good.

Description

technical field [0001] The invention relates to the field of fabric dyeing, in particular to a dyeing agent for nylon fabrics. Background technique [0002] Polyamide fiber, commonly known as nylon, has a density of 1.15g / cm. It is a general term for thermoplastic resins containing repeated amide groups—[NHCO]—on the main molecular chain, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its naming depends on the specific number of carbon atoms in the synthetic monomer. Invented by the famous American chemist Carothers and his research team. Nylon is a term for polyamide fibers that can be made into long or short fibers. Nylon 6 is polycaprolactam and nylon 66 is polyhexamethylene adipamide. Nylon 66 is 12% harder than nylon 6, and theoretically speaking, the higher the hardness, the more brittle the fiber and the easier it is to break. But nylon fabric is not easy to col...
