The method comprises the following steps of: uniformly mixing the printing raw paste, oxalic acid, urea, a chelating dispersant maleic acid-acrylic copolymer, a non-ionic penetrant and water to prepare mordant removal color paste; printing patterns on the silk or wool fabric pre-mordanted by a metal mordant by use of natural dye according to the required printing pattern; printing the mordant removal color paste on the white ground part of the printed fabric; and performing drying, steaming, washing and drying according to the conventional printing technology to obtain the natural dye printed fabric. The method disclosed by the invention adopts a composition with an effect of removing the colored mordant on the ground color of the printed fabric, and prints the removal color paste on the white ground part without patterns to obtain the natural dye printed fabric with white ground color; the aftertreatment technology is the same as the conventional printing technology, and additional process is not needed; and meanwhile, the grade and added value of the natural dye printed fabric are increased.
Description
Technical field
The present invention relates to fabrics printing and dyeing process technology, particularly a kind of white method of mordant on the ground of natural dye PRINTED FABRIC of removing, belongs to textile printing and dyeing processing technique field.
Background technology
Textiles, in order to obtain the pattern of gay colours and glamour, must adopt different dyestuffs to dye or stamp processing.The developing into us and bring convenience dyeing and printing process technology and the gorgeous world efficiently of synthetic dyestuffs, yet the pollution that the high chemical stability of synthetic dyestuffs and low biodegradability have increased treatment of dyeing wastewater difficulty, increased the weight of ecological environment to cause, synthetic dyestuffs also show especially day by day to the harm of human body.Natural dye and Environmental compatibility are good, biodegradable and nontoxic, and skin, without anaphylaxis and carcinogenic, is met to the ecological requirement of textiles, aspect the high-grade ecological textile of exploitation, have obvious advantage.
In recent years, natural dye is very extensive for the correlative study of textile dyeing.Due to the molecular weight of natural dye, hydrophobic structure is little, with interfibrous Van der Waals force and hydrophobicity effect all a little less than, the affinity to fiber during natural dye dying is more much lower than synthetic dyestuffs, in addition, the molar absorption coefficient of dyestuff is also smaller.Therefore, adopt natural dye dying often to use mordant to process or other processing methods, to increase the dye-uptake of dyestuff on fiber.As the mordant of natural dye, mainly contain the salt of the metal ions such as copper, iron, aluminium, the method for mordant dyeing is divided into first matchmaker and rear matchmaker processes.It is generally with after a certain amount of mordant solution-treated fabric that first matchmaker processes, then dyes with natural dye; It is that fabric first passes through natural dye dying that rear matchmaker processes, and then with certain density mordant, processes.Metal ion in mordant can with dye molecule in hydroxyl, carbonyl etc. form complex, can also with fiber in hydroxyl, amino and carbonyl form complex thing, between dyestuff and fiber, by metal ion, form connection bridge, increased on the one hand the dye-uptake of dyestuff on fiber; Strengthened on the other hand the combination of dyestuff and fiber, be conducive to improve every fastness of DYED FABRICS, in addition, the metal ion in complex can promote the pi-electron in dyestuff conjugated system to flow, and can produce hyperchromic effect.
Stamp is to make dyestuff on fabric, form the process of the floral designs with different color.The stamp processing of synthetic dyestuffs is very general.If but adopt natural dye stamp just to have the problem of how to carry out mordant dyeing processing.
Document (S. Kale, S. Naik, R. Gaikwad. Mordant Printed Cotton Fabric Dyed in Natural Dye[J]. Man-made Textiles in India, 2009 (8): 279-281.) reported with the mill base that contains metal salt mordant and printed on real silk, the method dyeing with English walnut pigment again, the deficiency of its existence is that the ground color part that does not print mordant has also been caught color simultaneously, just ground colour is different with pattern color, and can not obtain ground colour is white PRINTED FABRIC.Document (M.Gablot, N.Papni, N.Fatima et a1. Printing with natural dyes [J] .International Dyer, 2005 (9): 18-20.) reported pre-mordant dyeing and the synchronous two kinds of methods of mordant dyeing of adopting, during synchronous mordant dyeing, mordant and dyestuff are directly put into mill base, fabric is carried out to stamp, the deficiency of this method is the dyestuff in mill base, between mordant and printing gum, may there is coordination combination, the unstable of mill base will be caused on the one hand, can affect on the other hand dyestuff to the transfer of fiber, and then cause tinctorial yield to decline.The method of pre-mordant dyeing is to want the fabric of stamp first by a certain amount of mordant solution integral body, to carry out mordant dyeing processing, then by pattern, carries out stamp, and stability of pigment paste and the reappearance of this method are relatively good.But the deficiency of this method is most of metal ions for mordant dyeing there is certain color, can cause the color that stay white ground color part to embody metal ion, and can not obtain equally ground colour is white PRINTED FABRIC.As from the foregoing, also there is the problem that needs solution in natural dye for printing in textiles.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, provide a kind of and can effectively remove the white mordant on the ground of natural dye PRINTED FABRIC, improve the mordant of natural dye mordant dyeing printing quality and remove mill base and application thereof.
Technical scheme of the present invention is to provide a kind of white method of mordant on the ground of natural dye PRINTED FABRIC of removing, and comprises the steps:
(1) by weight percentage, by the former paste 50～80% of stamp, oxalic acid 0.3～1.0%, urea 2～5%, chelated dispersants maleic acid-acrylic acid copolymer 0.5～2.5%, nonionic penetrant 0.01～0.1%, water 15～40%, mixes, and prepares mordant and removes mill base;
(2) by silk or wool fabric after the pre-mordant dyeing of metal salt mordant is processed, according to required decalcomania natural dye impressing pattern, in the white ground of PRINTED FABRIC part, print mordant and remove mill base, again routinely printing technology dry, decatize, washing, drying and processing, obtain a kind of natural dye PRINTED FABRIC.
Described nonionic penetrant is a kind of in fatty alcohol polyethenoxy ether class non-ionic surface active agent JFC or AEO9.
