Description

A kind of textile auxiliary for improving color fastness and preparation method thereof
Technical field
The present invention relates to textile auxiliary field, more particularly to a kind of textile auxiliary for improving color fastness and its preparation side Method.
Background technology
Reactive dye chromatogram is complete, lovely luster, with preferable color fastness, but carboxyl, sulfonic group are carried on dyestuff Deng water soluble group so that wet colour fastness is not good, especially wet rubbing fastness.Although reactive dye can be formed altogether with fiber Valence link is combined, but in dyeing, if in the presence of to hydrolised dye or the dyestuff that is not bonded soaps insufficient, can also make wet colour fastness Decline, and be also possible to decompose scission of link under acid or alkaline conditions with the established covalent bond of fiber, so as to reduce color fastness. Therefore, use can improve the textile auxiliary of reactive dye color fastness and the fabric after dyeing is arranged, with higher reality With value.
The principle that processing raising dyestuff color fastness is carried out to fabric using textile auxiliary has following a few classes：(1) auxiliary agent is utilized Infusible precipitate is generated with dyestuff；(2) it is crosslinked using the reactive group in auxiliary molecules and dyestuff so that dye molecule More closely it is combined together with fiber；(3) film forming using auxiliary agent on fabric, the dyestuff being now either bonded point The dye molecule that son is not still bonded all will be firmly coated on fiber surface, so as to prevent that dyestuff from coming off；(4) auxiliary agent is utilized Molecule and interfibrous intermolecular attraction, such as Van der Waals force and hydrogen bond gravitation；(5) knitted using the buffer capacity of auxiliary agent with improving Perspiration fastness of thing etc..Needed for the textile auxiliary that can improve fabric color fastness with following characteristics：, should after its arrangement There is no discoloration, the glossiness of fabric is not influenceed；Every dyefastness should be able to comprehensively be mentioned；There should be security etc..
Chinese patent CN201610246541.1 discloses a kind of textile auxiliary for improving colour fixation, with following weight The raw material proportioning of part：45-55 parts of AEO, 40-50 parts of 3- chloro-2-hydroxypropyl-trimethyl ammonium chlorides, dodecane 35-45 parts of base ammonium benzene sulfonate, 35-45 parts of Sodium Polyacrylate, 30-40 parts of SPTS, quino dimethylacrylate 25-35 parts, 20-30 parts of phthalic anhydride, 15-25 parts of transparent butadiene-styrene impact resin, 15-25 parts of catechin, polyoxyethylene nonyl phenyl 10-20 parts of vinethene, 10-20 parts of white carbon, 5-10 parts of crosslinking agent, 5-10 parts of softening agent, so as to improve consolidating for textile Color effect simultaneously has reduction fabric concurrently and scouringed and bleaching the performance of temperature, but it is keeping fabric feeling good etc. that method need to be improved.
The content of the invention
It is an object of the invention to provide a kind of textile auxiliary for improving color fastness and preparation method thereof, fabric is through being somebody's turn to do after dyeing After textile auxiliary is arranged, the water-fastness degree of dyeing, abrasion resistance and fastness to perspiration are effectively increased, and fabric can be protected Hold the feel of high-quality.
