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
The invention belongs to dyeing and finishing technique field, be specifically related to a kind of REACTIVE DYES roll-dry-steam dyeing fixation alkaline agent.
Background technology
REACTIVE DYES is cellulosic fibre and blending or the topmost dye species of intertexture, and reactive pad dyeing technique is because its dyeing efficiency is high, produce and extensively adopt with respect to contaminating few, the applicable serialization in enormous quantities of water consumption.At present, colouring method and pluses and minuses thereof that reactive pad dyeing mainly adopts are as follows: (1) is rolled-dried-steam or roll-dry-roasting technique: the main feature of this technique is that DYED FABRICS is padded to the mixed solution that contains REACTIVE DYES and fixation alkaline agent (conventional sodium bicarbonate, sodium carbonate, NaOH or its mixture) simultaneously, its production efficiency is high, but the subject matter existing is REACTIVE DYES can be hydrolyzed in the process of rolling and drying, cause dye utilization rate not high, even the REACTIVE DYES of some facile hydrolysis can not adopt this technique, (2) roll-dry-roll-steam technique: the main feature of this technique is first DYED FABRICS to be padded to the solution that contains REACTIVE DYES, fabric after oven dry pads the solution that contains fixation alkaline agent and neutral electrolyte (conventional salt or glauber salt) again, then vapour steaming colour fixing, this technique has well solved the hydrolysis problem of REACTIVE DYES, but dyeing flow is long, the neutral electrolyte that contains high concentration in dyeing waste water has strengthened intractability and the cost of dyeing waste water, (3) wet short steaming: this technique is a kind of REACTIVE DYES new dyeing technique of developing in recent years, its key step is roll-preliminary drying-high temperature steaming, its main feature is that the fabric padding after dyestuff and alkaline agent adopts infrared preliminary drying (moisture percentage 30% left and right after preliminary drying), then decatize under half wet condition of 140 DEG C, because fabric contains moisture and steam temperature is high, so it is high that the advantage of this technique maximum is production efficiency, save the energy, but during due to decatize, need very high temperature, therefore the greatest problem that this technique is promoted is at present that equipment cost is higher, conventional pad dyeing equipment cannot carry out wet short steaming.
Summary of the invention
The object of the invention is to the shortcoming for cellulosic fibre and blending or intertexture reactive pad dyeing dyeing, a kind of new dyeing prescription is provided, this method utilize sodium trichloroacetate and trichloroacetic acid blending ingredients as REACTIVE DYES roll-dry-steam the fixation alkaline agent of pad dyeing, both solved conventionally roll-dry-steam the hydrolysis problem of REACTIVE DYES while dyeing, avoid again rolling-drying-roll-steam the shortcoming such as production cost height and complex procedures while dyeing, and overcome the high problem of equipment cost of wet short steaming.The product color making is even, has good fastness to washing and fastness to rubbing.
Technical scheme of the present invention is: a kind of for REACTIVE DYES roll-dry-steam dyeing fixation alkaline agent, REACTIVE DYES rolls-dries-and steam colouring method and comprise fabric is put into padding liquid dyeing, oven dry, vapour steaming colour fixing, washed, soaps, washes, dries, described padding liquid is made up of REACTIVE DYES, fixation alkaline agent, urea, bleeding agent, reservehao S, migration inhibitor, described fixation alkaline agent is made up of the raw material of following parts by weight: sodium trichloroacetate 10～100g/L, trichloroacetic acid 1～5g/L.
Described padding liquid is made up of the raw material of following parts by weight: REACTIVE DYES 2-50g/L, and sodium trichloroacetate 10～100g/L, trichloroacetic acid 1～5g/L, urea 10-100g/L, bleeding agent 1-10g/L, reservehao S 5-20g/L, migration inhibitor 5-30g/L, surplus is water.
Described bleeding agent is penetrating agent JFC or penetrant t.
Described migration inhibitor is migration inhibitor MS or sodium alginate.
The chemical formula of described REACTIVE DYES is as follows: wherein D represents the precursor structure of dyestuff, and R represents substituting group (except halogen).
The active group of described REACTIVE DYES is at least one in following active group, and wherein D represents the precursor structure of dyestuff, and R represents substituting group (except halogen).
The invention has the beneficial effects as follows: the alkaline agent that the present invention adopts the mixture of sodium trichloroacetate and trichloroacetic acid to replace to use in traditional handicraft to cellulose fibre and blending thereof or intertexture roll-dry-steam knot dyeing technology.
(1) adopt sodium trichloroacetate and trichloroacetic acid mixture as cellulose fibre and blending thereof or intertexture REACTIVE DYES roll-dry-steam the fixation alkaline agent dyeing, reduced with respect to traditional rolling-dry-steam technique the problem that the hydrolysis of REACTIVE DYES brings, and the present invention is to REACTIVE DYES non-selectivity; With respect to traditional rolling-dry-rolling-steam technique has shortened technological process, has saved the consumption of salt, has reduced the intractability of dyeing waste water; With respect to the wet short steaming of developing in recent years, reduce the requirement to equipment, can on conventional padding mangles, carry out.
(2) product colour making is even, has good fastness to washing and fastness to rubbing;
(3) simple, the convenient operation of technical scheme technique of the present invention, without particular/special requirement, utilizes conventional pad dyeing dyeing installation just can carry out large-scale production to equipment, has broad application prospects.
