Abstract

The invention relates to the technical field of fabric dyeing and finishing, in particular to a brocade and cotton blended fabric dyeing method which comprises the following steps: padding a brocade and cotton blended fabric with acid dye, performing primary steaming, performing primary washing, performing primary soaping, performing primary ironing drying, padding the brocade and cotton blended fabric with reactive dye, performing secondary steaming, performing secondary washing, performing secondary soaping, performing secondary ironing drying and performing after-treatment. Wherein during primary soaping, an anion color fixing agent is added into a soaping agent; a finishing agent in after-finishing is a cationic color fixing agent. According to the dyeing method provided by the invention, the chinlon blended fabric is deeply dyed, the color fastness is high, and compared with an existing deep color process, the dye dosage can be obviously reduced, the technological process is shortened, meanwhile, the cost is reduced, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing method for nylon-cotton blended fabrics. Background technique [0002] Nylon is the trade name for polyamide fibers. Nylon has a series of excellent properties, such as abrasion resistance, good elasticity, high strength and elongation, small specific gravity, mildew resistance and moth resistance. The morphological structure of nylon is smooth in the longitudinal direction, and the cross-section is close to a circle. The main chain of macromolecules is composed of carbon atoms and nitrogen atoms with the same regularity. There are no side groups on the main chain, and it is easy to form crystals. Among all natural fibers and chemical fibers, nylon has the highest resilience, and the macromolecular structure of nylon has a large amount of methylene-CH-. In the relaxed state, the fiber macromolecules tend to be in a state of random curling. When subje...
