Abstract
The invention discloses a preparation method and an application of a reactive cellulose fiber cationization modifier-poly (GMA-co-AM-co-DMC). In an aqueous solution of beta-cyclodextrin (beta-CD), a free radical copolymerization reaction is performed on three monomers of glycidyl methacrylate (GMA), acrylamide (AM) and methacryloyloxyethyl trimethyl ammonium chloride (DMC) in the presence of an oxidation/reduction (potassium persulfate/sodium bisulfite) initiation system, to prepare a product. The preparation method of the product is simple and the energy consumption is low; in a polymerization process, no surfactant needs to be added in the aqueous solution to solubilize a hydrophobic monomer GMA, so that the environmental pollution is small; the product is a white powdery solid, is water-soluble, can be used for establishing a chemical bond with cellulose fiber and is unlikely to drop from the fiber in a dyeing process of an active dye, so that the dyeing promotion effect is stable. In a soaping process of a colored fiber, cationic groups in the modifier drop from the fiber to take away hydrolyzed dyes on the surface of the fiber, thereby improving the color fastness of colored fiber.

At present, adopt the dyeing waste water difficulty of general materialization or biochemical method processing supersalinity larger, cost is higher.Therefore, the less salt of cellulosic fibre reactive dyestuffs or salt-free dyeing research receive much concern.Realize the cationization that one of important channel of cellulosic fibre reactive dyestuffs less salt or salt-free dyeing is cellulosic fibre.It normally adopts cationoid reagent, under certain condition, cellulosic fibre is processed, and by chemistry or physical action, cationoid reagent is adsorbed on fiber.Fiber after modification in dye bath by the original electronegative positive charge changing into some amount, the anionic dyestuff in strong adsorption dye bath, thus improve the dye uptake of dyestuff.
Cation-modified reagent comprises small molecule monomer class and high score subclass.Small molecule monomer class properties-correcting agent good penetrability, is beneficial to level dyeing and thoroughly dyes, but consumption is large; Comparatively speaking, high score subclass properties-correcting agent is high to the avidity of cellulosic fibre, can reduce its working concentration.The present invention has designed and synthesized a kind of reactive polymer reactant, for the cationization of cellulosic fibre, realizes the salt-free dyeing and printing process of cellulosic fibre after modification, and improves the utilization ratio of dyestuff, reduces the pollution of dyeing waste water to environment.Reactive cation modifying reagent can be set up chemical bond with cellulosic fibre, and the possibility coming off from fiber in dyeing course reduces, and Color is better.And in the process of soaping, the hydrolised dye of fiber surface can leave along with coming off of properties-correcting agent cation group, thereby the colour fastness of coloured fiber is higher, especially crock fastness.
