Activated dye processing aid and preparation method thereof

Abstract

The invention provides an activated dye processing aid and a preparation method thereof. The activated dye processing aid is prepared from the following ingredients by mass percent: 30 to 60 parts ofamphoteric ionic surface active agent, 20 to 50 parts of non-ionic surface active agent, 3 to 40 parts of poly-amine compound, 4 to 20 parts of chlorinated rare earth, 3 to 16 parts of organic acid complexing agent and 1 to 3 parts of nano oxide. The activated dye processing aid can achieve color fixation and detergent washing effects at the same time after activated dye dyeing, can replace a dyefixing agent and a soaping agent in an original traditional technology and can meet a national dyeing fastness standard; furthermore, a technological process and time are shortened, energy consumptionand water consumption in dyeing are reduced, chromaticity of dyeing sewage is reduced, a sewage draining amount is reduced, and ecological environment is protected.

Description

technical field [0001] The present invention relates to reactive dye processing aids. Background technique [0002] After dyeing, reactive dyes need to be fully washed with water to remove hydrolyzed dyes and floating colors on the fibers. In order to improve the color fastness of some dark-colored products, color fixing treatment is required after dyeing. Therefore, the dyeing process is long and consumes a lot of water and energy. For a long time, improving the process, researching and developing products and processes that improve the quality of dyes, increase the dyeing uptake rate, improve the washing effect after dyeing, improve the color fixing effect of dyes, reduce sewage discharge, save energy and reduce consumption have become urgent problems to be solved. Due to the limitations of the processing technology in the prior art, the dyeing and fading of pure cotton fabrics is usually dyed with sulfur dyes, vat dyes, and paints. Utilizing the characteristics of the po...

Problems solved by technology

However, it is difficult to obtain a satisfactory washing effect when dyeing with reactive dyes.

[0003] There are many disadvantages in conventional paint dyeing: (1) Uneven color fixation, the color film formed by the adhesive and small pigment particles can only form scattered distributions such as spots, flakes, and dots, and cannot be uniform, continuous, and completely covered. On the fiber surface, the general color film covers 35% to 85% of the fiber area; (2) the use of a large amount of thick and hard adhesive on the surface of the fabric, there are more colored films bonded between the fibers, the performance of the adhesive itself and the fiber surface Uneven distribution forms a rough surface, which causes the fabric to feel hard and poor in elasticity; (3) Low color fastness. The color film formed by the tiny particles of the paint and the binder and the fiber are attached to the fabric only by the intermolecular van der Waals force. On the surface, the color fastness is significantly lower than that of dyes, especially in the post-processing "washing" production process and the use process after processing into clothing, the worse the color fastness is, which seriously restricts the popularization and application of paint dyeing technology; (4) The dyeing surface is narrow. The paint dyeing process is suitable for a narrow surface. When dyeing a deep base color, the cloth surface is prone to stains and willows. Therefore, it can only be dyed with light and medium colors. Some fabric varieties and some colors are produced or only used for printing and dyeing. (5) The controllability is poor, the problem of sticking rolls is prone to occur in the intermittent production process operation, the quality controllability is poor, the quality fluctuates greatly, and the intermittent dyeing production of the jigger is mostly used, and the output is low
