Abstract

The invention discloses fixation alkali for rolling-drying-steaming dyeing of reactive dye. A method for rolling-drying-steaming dyeing of reactive dye includes: putting a fabric into pad rolling solution for dyeing, drying, steaming fixation, water washing, soap washing, water washing and drying. The pad rolling solution is composed of reactive dye, fixation alkali, urea, penetrant, reserve salt S and migration inhibitor. The fixation alkali is made of, by weight, 10-100g / L of sodium trichloroacetate and 1-5g / L of trichloroacetic acid. Alkali used in traditional processes is replaced by the mixture of the sodium trichloroacetate and the trichloroacetic acid for rolling-drying-steaming pad dyeing process of cellulose fibers and blends thereof or intertextures, and prepared products are uniform in color and have high fastness to washing and high fastness to abrasion. The technical scheme of the fixation alkali is simple in process and convenient to operate, has no special requirement on equipment and have wide application prospect, and mass production can be realized by means of conventional pad dyeing equipment.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, in particular to a color-fixing alkali agent for pad-dry-steam dyeing of reactive dyes. Background technique [0002] Reactive dyes are the most important dyes for cellulose fibers and their blended or interwoven fabrics, and the pad dyeing process of reactive dyes is widely used because of its high dyeing efficiency, less water consumption than exhaust dyeing, and suitable for large-scale continuous production. At present, the main dyeing methods and their advantages and disadvantages of reactive dye pad dyeing are as follows: (1) Pad-dry-steam or pad-bake-bake process: the main feature of this process is to simultaneously pad dyed fabrics containing reactive dyes and solids. The mixed solution of color base agent (commonly used sodium bicarbonate, sodium carbonate, sodium hydroxide or their mixture) has high production efficiency, but the main problem is that the reactive dye will ...
