The method has very obvious practical value.
Description
Technical field
The present invention relates to a kind of bright and beautiful cotton (gluing) fabric dyeing method, be specifically related to cotton (gluing) fabric acidity of a kind of brocade or neutrality and REACTIVE DYES with bathing the dip dyeing method.
Background technology
Brocade/cotton (gluing) fabric is current lining all the fashion.Cotton, viscose is soft, comfortable and easy to wear, sucting wet air permeability is good, but creases easily; The nylon fibre good springiness, the intensity height, light weight is wear-resisting, and hygroscopicity is also better, and brocade/cotton (gluing) fabric side section then has both the advantage of two kinds of fibers simultaneously, complementary again not enough, both had strong body bone, had smooth, plentiful feel again, and after dyeing and finishing processing, given fabric random comfortableness, have good wearability, liked by the consumer.But because brocade and cotton have different interior molecules structures has caused the difference of their dyeability, this brings certain degree of difficulty to dyeing processing, thereby its dyeing is that present colourist is worth the problem inquiring into and study.
Traditional brocade/cotton (gluing) fabric generally adopts dispersion/direct, acid (neutrality)/directly, acid (neutrality)/active two bath methods dyeing.For high-grade brocade/cotton (gluing) fabric all with acidity (neutrality)/reactive dyeing, its dyeing long flow path, energy resource consumption is big.How shortening dyeing, reduce the consumption of the energy and the water yield, enhance productivity and the quality of product, is the technical barrier that presses for solution.
Cotton (gluing) fiber in high-grade brocade/cotton (gluing) fabric is all with reactive dyeing.Advantages such as REACTIVE DYES has lovely luster, and dyeing is convenient, and dyefastness is good.Have duality but add alkali during reactive dyeing, under alkali condition, help dyestuff and combine, but the existence of alkali also can make the dyestuff hydrolysis and lose efficacy with fiber-reactive.The power of alkaline agent and consumption are one of main keys of influence brocade/cotton (gluing) textile dyeing product quality during dyeing.It is the set alkaline agent that present factory REACTIVE DYES brocade/cotton (gluing) fabric exhaust dyeing generally adopts soda ash, and (be generally 10～15g/L, dark color reaches 15～25g/L) to its large usage quantity.When dyeing, dyeing condition acid or neutral and REACTIVE DYES is far from it simultaneously, and acid or neutral generally the need dyeed under acid condition, and REACTIVE DYES needs to dye under alkali condition, the dyeing of therefore general employing two bath methods, and its production efficiency is low, technology is long, influences output and production cost.
Summary of the invention
The object of the present invention is to provide cotton (gluing) fabric acidity of a kind of brocade or neutrality and REACTIVE DYES with bathing the dip dyeing method, adopt REACTIVE DYES elder generation's low temperature (60～65 ℃) or two temperature (being respectively 60～65 ℃ and 80～85 ℃) and add alkali (pH value 11～11.5), and then add acid (to pH value 5～6) and heat up (95～98 ℃) use acidity (neutrality) dyestuff to Dyeing Polyamide Fibre cotton fiber dyeing.In REACTIVE DYES is soaped process, again acid (neutrality) dyestuff is carried out the method for fixation simultaneously.This will shorten dyeing time greatly, improve output, reduce the energy, the consumption of the water yield and the consumption of alkali, thereby reduce production costs, and the content of alkali reduces in the sewage simultaneously, helps environmental protection.When acidity (neutrality) dyeing, dye liquor is the buffer system that sodium acetate and acetic acid are formed, and dyeing reappearance (dyeing one-time success rate) is improved, and minimizing is returned something for repairs.
The one-bath two-step process dyeing course and the principle of invention:
Dyeing course:
One, one of one-bath two-step process dyeing course:
---KN type REACTIVE DYES (60～65 ℃) dyeing---acid (neutrality) dyestuff high temperature (95～98 ℃) dyeing---fixation, the soap---washing of brocade/cotton (gluing) fabric
Two, two of the one-bath two-step process dyeing course:
---the two temperature of B, M, BF type REACTIVE DYES (being respectively 60～65 ℃ and 80～85 ℃) dyeing---acid (neutrality) dyestuff high temperature (95～98 ℃) dyeing---fixation, the soap---washing of brocade/cotton (gluing) fabric
Inventive principle:
Acid (the neutrality)/reactive dyeing of brocade/cotton (gluing) fabric.REACTIVE DYES is because the active group difference can be divided into vinyl sulfone(Remzaol structure (KN type) dyestuff, a chloro-s-triazine structure (K, KD, KE type) dye well one chloro-s-triazine and vinyl sulfone double-active group structure (B, M, BF type) dyestuff etc.No matter which class dyestuff, the active group in its molecular structure of dye needs to combine with fiber generation chemical reaction under alkalescence and certain dyeing temperature condition.And acid (neutrality) dyestuff generally needs dyeing under high temperature (95～98 ℃) and acid condition, most of acid (neutrality) dyestuff can influence the dye-uptake of dyestuff under alkali condition, and REACTIVE DYES active group generation hydrolysis in the dye molecule and losing efficacy under hot conditions.Therefore generally adopt two bath process for brocade/cotton (gluing) fabric with acid (neutrality)/reactive dyeing.
Acid (neutrality)/REACTIVE DYES one-bath two-step process dyeing theoretically, can under alkalescence and cryogenic conditions, dye viscose glue or cotton earlier, the dyeing later stage adds acid and heats up dyes polyamide fibre again, the soda ash of factory's reactive dyestuffs in exhaustion normal dyeing employing at present is the set alkaline agent, its large usage quantity (being generally about 20g/L).The dyeing later stage adds in a large amount of acetic acid (needing about 30g/L) ability and the soda ash of 20g/L, also must add certain acetic acid simultaneously, just can reach the needs of acid (neutrality) dyeing.This is feasible from theoretical research, but does not possess practicality, is difficult to suitability for industrialized production.
This method selects for use caustic soda to replace the soda ash set when reactive dyeing, because caustic soda alkalescence is strong, its consumption (according to shade) only needs about 1g/L just, and (the strong reaction rate of alkalescence is fast, easily produces dyeing look flower but the caustic soda set is difficult to the control dyeing quality; Dye stability is poor, easily produces problems such as aberration, cylinder difference).Add the stabilizing agent that shields during dyeing, can improve reactive dyeing stability, with control dyeing product quality.Use the caustic soda set during dyeing, the consumption of its alkali is about 1/20th of a normal dyeing, and the dyeing later stage only need add 3g/L left and right sides acetic acid and just can neutralize to satisfy the acid dyeing needs.Thereby add acid behind acidity of making (neutrality)/REACTIVE DYES elder generation alkali and intensification one-bath two-step process dyeing becomes possibility.
This method adopts KN type (vinyl sulfone(Remzaol structure) REACTIVE DYES elder generation's low temperature (dyeing temperature is 60～65 ℃) or B, M, BF type (chloro-s-triazine and vinyl sulfone(Remzaol double structure) REACTIVE DYES two temperature (being respectively 60～65 ℃ and 80～85 ℃ of dyeing) and add alkali (pH value 11～11.5) to cotton or viscose fiber staining earlier, and then adds acid (to pH value 5～6) and intensification (95～98 ℃) uses acidity (neutrality) dyeing to Dyeing Polyamide Fibre.Adopt distinctive method simultaneously, in REACTIVE DYES is soaped process, simultaneously again to the fixation of acid (neutrality) dyestuff.This shortens dyeing greatly, improves output, reduces the energy, the consumption of the water yield and the consumption of alkali, thereby reduces production costs, and the content of alkali reduces in the sewage simultaneously, helps environmental protection.The present invention has fairly obvious practical value.
