Abstract
The invention relates to a green and environment-friendly textile printing process comprising the steps of: size mixing, printing and aging, wherein the step of size mixing includes color paste preparation and raw paste preparation; in the color paste preparation, chemicals stirring is carried out according to a proportion of color paste, and then a color fixing agent is added to be stirred to be uniform; in the raw paste preparation, pure sodium alginate is added to the prepared color paste to carry out size mixing until reaching the corresponding viscosity; the proportion of the color paste is that reactive dye takes up 5.5-6.5% of the total weight of color pulp, the color fixing agent RUF takes up 8-12% of the total weight of the color pulp, reserve salt S takes up 1-3% of the total weight of the color pulp, raw paste takes up 55-65% of the total weight of the color pulp, and water takes up 20-25% of the total weight of the color pulp; and the proportion of the raw paste is that sodium alginate takes up 2-6%, and water takes up 94-98%. According to the production process disclosed by the invention, the use of urea is not required, and therefore, the production cost is saved, and the environmental pollution is reduced; and the quality of a product is the same as that of the conventional printing products, and therefore, the process is a green printing process with sustainable development.
Description
Technical field
The invention belongs to the printing in textiles technical field, particularly a kind of technology for printing fabric made of environmental protection.
Technical background
Stamp is that dyestuff or coating are made mill base, executes spreading on the textiles, prints out the process of floral designs.With dyestuff furnishing mill base, after the stamp oven dry, usually evaporate, colour developing or fixation treatment during stamp, after soap, wash, fully remove thickener, chemical agent and loose colour in the mill base.Print paste is comprised of dyestuff, auxiliary agent and former paste.Dyestuff generally can be divided into direct dyes, azoic dyes insoluble azo dyes, REACTIVE DYES etc.Now, REACTIVE DYES is complete because of its chromatogram, and wet fastness is high, soft, has been the main dyestuff that the cellulose fibre stamp is used.REACTIVE DYES is extensive use on cotton, viscose glue, day silk, bast fiber fabrics not only, and also uses in a large number on the silk like fabric.The effect of former paste is dyestuff and chemical assistant etc. to be delivered to fabric get on, dyestuff behind the stamp (coating) set, and former paste itself does not react in the stamp process namely by flush away, mainly plays Transfer Medium.Auxiliary agent is generally urea; NaHCO
3Reservehao S etc., different according to the fabric fibre structure, add auxiliary agent.
REACTIVE DYES is widely used because of its many merits, but also has more problem in stamp, low such as degree of fixation, easily be stained with in vain, the problem such as dye diffusion infiltration difficulty.For addressing these problems, add a large amount of urea in the mill base of being everlasting in the production.The product that urea is carbon dioxide and ammonia under 180-200 ℃ and 200pa for white powder or crystal, has hygroscopy, and water-soluble with 1:1, solution is alkalescence.Urea has the performances such as hydrotropy, dissolving, moisture absorption, can be used for modulating dyestuff, the effect that helps the dyestuff dissolving and stablize mill base.Urea is as follows to the Main Function of REACTIVE DYES:
(1) though have hydrophilic sulfonic group in the reactive dyestuff molecule, solubility is better, and dye dosage is high during because of stamp, and bath raio is little, therefore still needs to come hydrotropy with urea.
(2) urea is hygroscopic agent, hygroscopic capacity about 24.4%.It has hygroscopic effect when decatize, can also promote swelling of fiber, is conducive to dyestuff penetration, improves tinctorial yield, and it is comparatively remarkable that the thermosetting dyestuff is got chromatic effect.
(3) urea is the moisture preservative in the mill base, and the minimum amount of general urea is 1%.When dye dosage was higher than 1%, amount of urea equated with dyestuff or increases 3%-5% again.
But reactive printing technique not only increases production cost because of a large amount of urea that use, and urea enters in the water body, natural decomposition becomes carbon dioxide and nitrogen-containing compound, and the latter can accelerate the growth of algae substances, finally causes the Water Eutrophication phenomenon, cause water body ammonia-nitrogen content superelevation, severe contamination.So, in today that environmental problem receives much concern, reduce urea and use, develop oliguresis element printing technology even become urgent problem without the urea printing technology.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the environmental protection technology for printing fabric made that does not add urea in a kind of REACTIVE DYES.
The present invention realizes by following technology:
A kind of environmental protection technology for printing fabric made, comprise and size mixing, stamp, evaporate operation, it is characterized in that: described size mixing comprise mill base preparation and former paste standby, mill base is prepared as in the mill base ratio and carries out the material stirring, rear adding color-fixing agent is stirred to evenly, and former paste is prepared as in the mill base that makes and adds pure sodium alginate and size mixing to corresponding viscosity; The proportioning of mill base be REACTIVE DYES account for the mill base gross weight 5.5～6.5%, Fixative R UF account for the mill base gross weight 8～12%, reservehao S account for the mill base gross weight 1～3%, former paste account for the mill base gross weight 55～65%, water accounts for 20～25% of mill base gross weight; The proportioning of former paste be sodium alginate account for former paste gross weight 2～6%, water accounts for 94～98% of former paste gross weight.
Described REACTIVE DYES adopts U.S.'s Hensel to step the PF series reactive printing dyes product that dying of weaving company provides, and comprises the products such as reactive red PF-2G, reactive red PF-2B, reactive yellow PF-4G and reactive yellow PF-2R; Fixative R UF steps the product that dying of weaving company provides for U.S.'s Hensel.
Described material water temperature is strict controlled in below 90 ℃, and the material temperature of a chloro-s-triazine type REACTIVE DYES is 80 ℃, and the material temperature of vinyl-sulfone reactive dyes does not allow above 70 ℃; Add first fixation alkali during material, consumption is every hectolitre 10Kg, carries out and the dyestuff mix and blend, adds 60 ℃ of warm water and carry out material when stirring, and material water is pitch-black bright state without particle, can stop stirring and place stand-by.
Described stamp will guarantee infiltration, and is positive and negative consistent, strictly controls the cropping humidity, is controlled at 20 ℃ ~ 30 ℃ of cloth cover eighty per cant dried cloth surface temperatures.
The described requirement humidity of evaporating reaches 0.4 ~ 0.8Kg, and cloth cover is tide slightly.
The present invention compared with prior art has the following advantages: do not need to add urea in the production technology of the present invention, saved production cost, reduced the pollution to environment; Its Printing quality and traditional Printing quality are as good as, and all reach national textile quality standard; And low-cost, low power consuming, of low pollution is a kind of green printing technology of Green Sustainable.
