Description

Color fixing agent for cotton for after-finishing and preparation method thereof
Technical Field
The invention particularly relates to synthesis of a color fixing agent, and particularly relates to a color fixing agent for cotton for after-finishing and a preparation method thereof.
Background
In the process of cotton textile processing, the processes of desizing, refining, bleaching, dyeing, after finishing and the like are required, wherein the dyeing process is very important, some cotton textiles can obtain bright colors through the action of dyes, but the dyes in the textiles can fall off from the dyed textiles under the action of oxygen in the air or the influence of humidity, so that the textiles fade, stain, cross color and the like, and therefore, in the dyeing process, a certain amount of color fixing agent is generally required to be added to enhance the fastness of the pigments on the textiles.
The color fixing agent for cotton is various, and is generally adsorbed inside fibers in a film forming mode or forms neutral ion lake with dye, so that the color fixing effect is achieved. The cotton fabric is usually subjected to color fixing and then soaping, and then after-finishing is carried out after soaping, wherein the main working procedures of after-finishing are softening by using a softening agent and drying and shaping. In order to shorten the dyeing and finishing process, the dyeing and finishing industry starts to research the simultaneous use of a color fixing agent and a softening agent, so as to achieve the effects of color fixing and softening. However, because the common softening agents are fatty acid amides, ester quaternaries and silicone oils, the color fixing agent is a relatively strong cation, and the softening agent is generally in an emulsion state, most of the softening agents cannot resist the strong cation and cannot be dissolved with the color fixing agent or be in one bath.
The special color fixing agent for after-finishing is carried out according to the requirements, and patent CN106758387A discloses an environment-friendly color fixing agent for formaldehyde-free chlorine-resistant cotton, which is prepared by preparing quaternary ammonium cellulose ether, a polyamine color fixing agent, a water-based polyammonium salt and an organic silicon polymer and then compounding the quaternary ammonium cellulose ether, the polyamine color fixing agent, the water-based polyammonium salt and the organic silicon polymer to form the color fixing agent for the formaldehyde-free chlorine-resistant cotton; patent CN110804886A discloses a pure cotton color fixing agent and a preparation method thereof, the color fixing agent is prepared by using vinyl acetate and triallylamine solution in salicylic acid and piperidine and initiating polymerization by benzoyl peroxide; patent CN103669050A discloses a fabric formaldehyde-free color fixing agent, which is mainly compounded by poly dimethyl diallyl ammonium chloride, hydroxypropyl trimethyl ammonium chloride chitosan, ethanol and fatty alcohol polyoxyethylene ether to form a formaldehyde-free color fixing agent, the action mechanism is that a cationic group in the color fixing agent component is electrostatically combined with an anionic group in the dye to form insoluble color lake on the surface of the fabric, the water solvent group of the dye is sealed, and the dyeing efficiency is improved in the dyeing process; however, these color fixing agents have poor compatibility with the softening agent, and firstly, the color fixing agents destroy the stable system of the softening agent, secondly, the color fixing agents cannot play a softening role, the whole color fixing effect of the cotton fabric in the after-treatment process is reduced, and the using effect of the softening agent is weakened.
