Abstract

The invention relates to a salt-free dyeing method with short liquor dyeing and ultra light color using an active dye. The salt-free dyeing method is characterized by comprising the following steps of (1) pretreatment of a cloth blank; (2) dyeing by the active dye; (3) neutralizing by glacial acetic acid; (4) boiling and washing; (5) softening; (6) taking out of a cylinder, and dewatering; (7) post-arrangement, drying and shaping. Compared with the conventional technology with ultra light color using the active dye which requires to add inorganic salt to promote the active dye to be adsorbed onto cotton fibers and then requires a large amount of cold and hot water to alternatively clean after dyeing is completed, the salt-free dyeing method has the advantages that the technology is simple, the process is greatly shortened, the energy consumption of materials is decreased, and the national spirit and concept of energy saving and emission reduction, clean production and sustained development of dyeing and printing enterprises are met.

Description

technical field [0001] The invention relates to a salt-free dyeing method for ultra-light color dyeing with small bath ratio of reactive dyes. Background technique [0002] As people's awareness of the ecological environment and the basic safety of textiles continues to strengthen, most of the current orders for infant clothing and underwear cotton knitwear that directly touch the skin are in special light-colored series such as beige, light pink and light blue. Reactive dyes are environmentally friendly dyes that chemically react with cellulose fibers. Because of their high wet fastness, they are the most widely used dyes for cotton knitwear. In the special light color dyeing process of reactive dyes for conventional cotton knitwear, the gray fabric is treated for about 60 minutes to make the capillary effect reach about 10 cm within 30 minutes, and the whiteness also meets certain requirements, and then add reactive dyes and salt dyeing adsorption at 40 degrees Finally, h...
