Description
Technology neck city:
The present invention relates to the cotton cloth reactive dye discharge printing process of textile and dyeing industry production aspect, both activity was pulled out activity, by adjusting process, improved deficiency, improved discharge, reached energy efficiency.
Background technology:
Discharge also can claim discharge printing, is a kind of special printing technology in the printing in textiles, is to develop from resist printing; Hold a high place in dyeing, because the discharge printing process relative complex requires height to operation, be to have artistry, top grade, high added value always.
Domestic textile printing and dyeing industry comprises the area, Shaoxing, and discharge printing process commonly used has coating discharge and reducing dye discharge, and it is to dye background color with REACTIVE DYES or Naphthol dyestuff, goes into the printing method of look with coating or reducing dye.
It will be argued that: coating discharge printing process fabrics feel and fastness are undesirable, owing to consider the fastness requirement more and more higher to the COAT PRINTING fabric, the self-cross linking monomer of the adhesive that domestic most enterprises produce is also still continued to use N hydroxymethyl acrylamide (account for monomer total amount 3%～5%), they bake with storage in can discharge free formaldehyde, make the free formaldehyde content on the PRINTED FABRIC be difficult to guarantee card, coating hides, of low grade, in case come off or fade and will reveal the defective of shape, so this is a urgent problem.
Reducing dye discharge existing problems: thickening agent cost height, chromatogram are incomplete, and technology is loaded down with trivial details, and reductant has a large amount of formaldehyde compositions and uses a large amount of the use, and chromatic colour is difficult to reach requirement, is restricted in application process.
Be described as follows:
1, reducing dye cost height is such as adopting Shanghai aircraft board reducing dye, 250-300 unit/kilogram that common stamp is used.Good is 500 yuan/kilogram, and chromatogram is incomplete.
2, the reducing dye discharge is that the employing rongalite is main, and potash compatibility, rongalite originally are the products that sodium hydrosulfite combines with formaldehyde, do not meet environmental protection, and a large amount of hydrogen are in use arranged, and have given play to formaldehyde in high temperature, and unpleasant rotten egg smell is arranged.
3, technological operation complexity, technology is loaded down with trivial details.
4. use a large amount of reductants, color is not bright-coloured to be difficult to reach requirement, is restricted in application process.
5, generally go up the printing and dyeing enterprise of scale, can't produce, increase supporting reduction special equipment.
For solve above discharge technology the problem deficiency, develop active discharge and substitute reduction discharge technology.With reference to external Korea S and Germany, also be to adopt rongalite (piece) and carving white zine (the solid zinc of moral) reducing dye discharge technology, so introduce the discharge technology of the U.S. cooperative development in Japanese common prosperity and Taiwan east, the active discharge technology of non-rongalite, Japan common prosperity commercial firm develops the special-purpose discharging agent EmyatexDK-TN of the rare sulfone type of second REACTIVE DYES and helps group agent Cleantex D-TN to beautify the worker with Tai Wandong and cooperate, select the painted of the Emvatex of anti-discharging agent DK-TN in the Mavco series REACTIVE DYES kind to the U.S. Chemical Manufacture in east, discharge Marcocion P type REACTIVE DYES, from Mavc0201 Vs type C vinyl sulfone(Remzaol REACTIVE DYES, select, the discharge better performances, Marvczo 1 COR series is dyed end REACTIVE DYES.
In introducing the active discharge technology and materials process of using Japanese common prosperity and east, Taiwan U.S., find to exist not enough problem.Be by have 1 in the Japanese technology discharge, dawn not enough cloth, 2, painted bad, 3, painted frame shadow, this is the problem that occurs on the cotton of pulling out property, get in touch with Dong Mei company, the cotton sample by its engineer testing is provided, these not enough problems are admitted to exist by Dong Mei company on cotton; Painted bad for orchil, tinctorial yield is low, and fixation rate is low, and problems such as washing fastness difference exist, and illustrates that day after day this expert also has no idea to solve.
Summary of the invention:
Apply the technology of the active discharge of cotton, the REACTIVE DYES advantage is that color and luster is complete, and technology is easy, and is soft, has good environmental protection; The price that this is active, than the low price 2/3 of reducing dye, going into look bright-coloured.At the problem of above-mentioned deficiency, technical barrier occurs in the active DISCHARGE PRINTING of solution cotton simultaneously, the raising discharge reaches dyeing and can produce active discharge, reaches to reduce cost.
Below explanation discharge technology key element is analyzed Japanese active discharge technology, analyzes the reason that active discharge goes wrong, and the technical scheme of implementing.
DISCHARGE PRINTING is to utilize between the molecule and reductant chemical change to take place in the thickening agent and the principle of colour killing realizes.DISCHARGE PRINTING spends the color and luster of shape to require difference to be divided into dawn according to pattern and look pulls out, the azo structure dyestuff that is used for some material of dyestuff of weaving face fabric, their contained azo groups can be reduced the agent decomposition and colour killing, but the colour killing of azo group must be evaporated processing; The difficulty or ease of colour killing are except that outside the Pass having with dyestuff, also need control and steam temperature, humidity, time and the correlation of spending, and baked, colour killing, through washing, soaping generates residue and slurry after removing colour killing, with the whiteness that improves pattern and lovely luster and look rate degree (reducing dye need oxidant develop the color) in addition.
The discharge technology of Japan's common prosperity is to adopt a good ammonia s-triazine type REACTIVE DYES and the vinyl sulfone(Remzaol REACTIVE DYES of alkali resistance, under strongly basic medium, make the principle of the ether chain fracture that the ethene alum combines with fiber easily, thereby carry out the new technology of REACTIVE DYES discharge REACTIVE DYES.
Marcozol CDR dyestuff is eastern U.S. Chemical Manufacture, and a kind of ethene alum REACTIVE DYES that is used for discharge is pulled out active artistic, coating as activity and pulled out the background color that active artistic, reduction pull out in the active printing technology and dye system, and can be used for active resist printing printing technology; When background color dyes system, can adopt continuous knot dyeing or overflow dyeing, such dyestuff has 14, can satisfy various dyeing requirements, and every fastness is good; Marcocion P type dye is the dyestuff that is used for the cotton fiber stamp, has lovely luster, good stability, alkaline resistance properties is good, lifting force is high characteristic, is used for the look of going into of DISCHARGE PRINTING in this technology.
Discharging agent DK-TN is the special-purpose discharging agent of a kind of ethene alum REACTIVE DYES of Japanese common prosperity Co., Ltd., is a kind of composite mixture.It not only contain can alkaline matter to the ehter bond hydrolysis of ethene alum one cellulose fibre outside, also contain the thickener that under alkali condition, still has good rheological characteristic and embrace water-based, to guarantee obtaining good printing effect when the stamp, and stable performance, the mill base that configures room temperature deposit can not decompose in the process rotten.
Japan common prosperity commercial firm, Tai Wandong beautify the technology of worker's discharge activity, exploitation is success, be to be used for the cotton discharge, this technological advantage, color and luster is complete, technology is easy, soft, have favorable environment protection, go into the look dyestuff, than reducing dye cheap 2/3, and bright-coloured, so have with using value well; Also there is the dawn deficiency in this technology, and is painted inaccurate, red coloredly goes into that rate is low to wait not enough problem.
In discharge is used, Yellow series, blue color system, go into the look rate still can, it is low that red series exists the look rate, set is low, washing fastness is low, and bright red tinctorial pattern is drawn a design and gone up machine production, by technological process, after washing, the oven dry, become very shallow, do not reach the color requirement like this as pink.
The reason of problem is 1, Japan is with discharge on shallow/middle background color style, and is domestic with the discharge of dark background color style, dawn difficulty; 2. it is strong and cause that tinctorial yield is low, fixation rate is low, to go into look dyestuff alkali resistance; 3. going into look dyestuff hydrolysis loose colour in the washing, too much to cause dawn not white.Reason is under the alkaline agent situation background color to be destroyed, and also has bad reaction to going into look simultaneously.
Take the technical scheme implemented: the adjusting process prescription, improve discharge dawn/coloring effect; The adjusting process flow process bakes high temperature earlier and removes look, after evaporate the color development set, improve discharge, taken precautions against control in the washing.
