Abstract

The invention relates to a one-bath, multi-color dyeing method for multi-component superfine fibers. At present, the two-bath, two-step method is usually adopted as the dyeing method for multi-component superfine fibers, the flow is long, the production cost is high, a great deal of time and energy are consumed, and the production efficiency is low. Colors are matched according to the coloring laws of dyes and fibers, i.e., with superfine polyester fibers, superfine polyester-cotton compound fibers and cationic dyeable superfine polyester fibers as materials and disperse dye, acid dye and cationic dye as dyes, multi-color schemes are combined and mixed; and by means of the sequential arrangement of feeding, the preparation and usage of anti-setting agent and a multi-stage heating process realizing the separate dyeing of the fibers corresponding to the dyes, the one-bath, multi-color dyeing of the multi-component superfine fibers are realized. The products dyed by the method disclosed by the invention have two or more different colors and good washing fastness and rubbing fastness, and are vivid, the dyeing effect is equal to the dyeing effect of the two-bath method, however, the dyeing process is simplified, and the consumption of chemicals, water and steam is reduced.

Description

technical field [0001] The invention relates to a one-bath multi-color dyeing method for multi-component superfine fibers, especially a one-bath multi-color dyeing process using anion and cationic dyes in the same bath, which is suitable for blending or interweaving of multi-component superfine fibers multicolor fabric dyeing. Background technique [0002] Ultrafine fiber is extremely fine, with large specific surface area, good capillary effect, good luster and moisture absorption and dissipation properties. It is widely used in various fields such as cleaning wipes, advanced artificial leather, filtration, medical and health care, and labor protection. [0003] The current superfine fibers are mainly polyester and polyester-nylon composite filaments. Polyester is usually dyed with disperse dyes; nylon can be directly dyed with acid, neutral and reactive dyes, and can also be dyed with disperse dyes. In recent years, due to the development of cationic modified polyester, ...
