Abstract
The invention discloses a method for preparing a sol dyeing solution and an application of the sol dyeing solution in dyeing of a textile, belonging to the spinning chemical technical field. The method directly adopts a dye or an active dye, a precursor, a coupling agent, a solvent, and a catalyst to prepare the sol dyeing solution. The dyeing by the method has simple technique, does not need the independent fixing agent to perform the fixing process, has small pollution and effectively increases the dyeing depth of the textile.
Description
Technical field
The invention belongs to technical field of textile chemical engineering, be specifically related to a kind of preparation and application of colloidal sol dyeing liquor.
Background technology
Sol-gel process is meant that inorganic matter or metal alkoxide solidify through solution, colloidal sol, gel, again the oxide that forms through heat treatment or the method for other compound solid.Sol-gel process can be used in the multiple industry.In recent years, the application of sol-gel process in textile industry is increasing.
At present, outlet textile fabric and clothes are more and more higher to the requirement of fastness, but fastness phenomenons on the low side such as many water-soluble dyes still exist friction, soap, Exposure to Sunlight have only 1 grade as the soaping fastness of direct light turquoise blue GL, fastness to wet rubbing has only 2 grades, and dry fastness also has only 3 grades.In addition, a lot of dyestuffs also exist the low problem of utilization rate in using, and as some REACTIVE DYES, degree of fixation is less than 60%.Handle at present often and reduce the water-disintegrable of dyestuff on the fiber, to improve dye utilization rate and dyefastness by color-fixing agent.
With color-fixing agent fabric being carried out fixation treatment has a lot of limitation, as causes that the color ligh modification of dyestuff, dyeing vividness reduce, introduced Cu
2+, Cr
3+Plasma has increased problems such as the difficulty of wastewater treatment and formaldehyde release.In addition, some color-fixing agent accommodations are narrow, as the type of the anti-chlorine polycation color-fixing agent based on dialkyl group allyl amine derivative, can prevent that look from becoming and the reduction of the light fastness of anti-chlorine, but the fastness to washing of fixation fabric are not very high.
Sol-gel technique can be applied to the textiles manufacture field to improve fixing property or to give textiles new function, as antistatic behaviour, water and oil repellant, anti-flammability, water retention property etc.Prepared titaniferous Nano sol with butyl titanate as presoma with sol-gel technique among the patent CN1587496, and adopt roll-dry by the fire-baking technology carries out anti UV finishing to COTTON FABRIC, fabric excellence, long-lasting ultraviolet radiation protective property are given in the use of combined with fluorescent brightening agent and synthetic latex simultaneously.Prepared a kind of Ludox among the patent CN1546781, adopt DYED FABRICS to pad the method for back arrangement, textiles carried out 100-180 ℃ heat treatment, make the thin and transparent gel film that on fabric, forms one deck inorganic network structure, the dye molecule net on fabric, is played tint retention to the dyestuff on the textiles.Method with this fixing finish is carried out fixation to DYED FABRICS, can improve the coloration of textile materials fastness, though can not bring the problem of environment and coloured light aspect, has prolonged the coloration of textile materials technological process.
This patent carries out hydridization with dyestuff and colloidal sol, forms new dyeing system.In this colloidal sol dyeing liquor to textile dyeing, because colloidal sol is transformed into the gel of the loose structure with adsorptivity in the process of baking, dyestuff is anchored in the formed gel film, has improved dye level and dyefastness, has simplified the dyeing flow process.
Summary of the invention:
The object of the present invention is to provide a kind of colloidal sol dyeing liquor.
Another object of the present invention provides a kind of preparation method of above-mentioned colloidal sol dyeing liquor, and this method is selected Soluble Anions dyestuff, presoma, coupling agent, catalyst, solvent, water for use, can be at a lower temperature as the room temperature preparation colloidal sol dyeing liquor.
Purpose of the present invention also provides the application of a kind of above-mentioned colloidal sol dyeing liquor dyeing aspect raising textile dyeing fastness and dye level.Promptly adopt colloidal sol dyeing liquor of the present invention fabric to be contaminated or pad dyeing dyeing processing, again through heat treatment, Ludox in the dyeing liquor carries out the embedding fixation at the three-dimensional netted film of fiber surface formation one deck porous to the dyestuff on the fabric, has improved dyefastness.
Compare with traditional dyeing, the present invention has following characteristics:
1. can improve the utilization rate of dyestuff;
2. dyeing is convenient, does not need to use separately the color-fixing agent fixation;
3. formaldehydeless;
4. can reduce dyeing temperature;
