Description
Technical field
The present invention relates to technical field of textile printing, particularly a kind of low temperature soaping agent of soaping for textile dyeing and preparation method thereof.
Technical background
To have chromatogram complete because of it for reactive dyestuffs, lovely luster, and cost is low, and dyeing is simple, can form the features such as covalent linkage with multiple fiber, and more than 80% cellulose dyeing and stamp all adopt reactive dyestuffs.But reactive dyestuffs in dyeing course can not with cellulosic fibre complete reaction, generally at 60%-70%, and upper dye fixed fiber in, dyestuff also can be hydrolyzed.These are dyestuff and the hydrolised dye of set not, and its diffusion and absorption property and original reactive dyestuffs are closely similar, is therefore easily attached to fiber surface, and diffuses into fiber.In the situation that alkaline agent and certain temperature, pressure, these not the dyestuff of set and hydrolised dye (loose colour) again part be combined with fiber, easily cause bleeding and stain again, have a strong impact on fastness to wet rubbing, washing fastness and the anti-staining performance of fabric.The technique of soaping can effectively be removed loose colour, guarantees colour fastness, and makes coloured light more bright-coloured and pure, effectively improves and guarantee the set of dyestuff.Therefore, soap washing is one of committed step of dyeing and printing products quality.
Traditional technology adopts soaping agent phosphorous and APEO to soap under the high temperature of 98～100 ℃, though high temperature is soaped, the loose colour that is conducive to fibrous inside spreads to fiber surface, but easily make reactive dyestuffs generation scission of link, produce a large amount of foams, not only affect the color and luster of product but also consumed a large amount of water, in waste liquid, also contain the tensio-active agent that environment is produced to dysgenic phosphorous and APEO class, be unfavorable for environmental protection.Exploitation is the target that printing and dyeing circle is pursued containing APEO, not phosphorous, good biocompatibility, soaping agent still, less energy-consumption.
Patent CN102093508A discloses a kind of low temperature non-foaming soaping agent and preparation method thereof, this macromolecular compound molecular structure is larger, be difficult to the hydrolised dye of fabric to clean, and synthesis condition is had relatively high expectations, complex process, product defectiveness also aspect anti-hard water.
Patent CN102424771A discloses a kind of low temperature soaping powder and preparation method thereof, its main component is horse-propylene copolymer, SPC-D and Sodium peroxoborate, because it has added a large amount of oxygenant (SPC-D, Sodium peroxoborate), although can reduce the colourity of sewage, can exert an influence to the coloured light of DYED FABRICS.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is, overcome the deficiencies in the prior art, a kind of low temperature soaping agent is provided, can to DYED FABRICS, soap at lesser temps (60 ℃), this low temperature soaping agent is not phosphorous, APEO, difficult for biological degradation compound, still, biodegradable, the effect of soaping is excellent, without adding sequestrant, resistance to hard water is strong, effectively prevent that loose colour from staiing again, play water saving, energy-saving and cost-reducing object.
For achieving the above object, the present invention is achieved by the following technical solutions: a kind of low temperature soaping agent, is mainly comprised of following each component by weight percentage:
Described each component of anion-nonionic tensio-active agent and content thereof (weight percent, is wt%):
