Recent research focus: 1) paper dyes energy, water, save time; 2) reasonable and simple production processes and operations (such as cleaning a small bath ratio of short-term); 3) low-cost, 4) reduce the amount of waste water treatment , environmental rationalization. Luttringer research suggests that a single functional group and two reactive functional groups soaping continuous processing of the temperature difference caused by different washing 1 4 High affinity dyes and hydrolysis without fixing dyes should rinse with water 3 ; PH value, salt concentration phosphorous acid and the flow ratio and soaping effects are closely related. Aspland's study suggests that high-affinity component washing, the washing with hot water will be better results, but will lead to changes in hue. Improper temperature or pH, can cause hydrolysis 2 . Thomsen's study suggests that 50% of the high-affinity hydrolysis of dye in high temperature rinse (95 ~ 70 ) when washed. GLBhalla of that double-molecule nucleophilic substitution reaction caused when alkaline soaping alkaline hydrolysis of dye, dye, and some rearrangement of bonding phenomena. Little Valley, etc. The best H3PO3 washing conditions described research; both to prevent the staining properties of white soap lotion application technology 6 . These studies have given reactive dye to prevent the staining properties of soap detergent to provide a basis for the development. 3 , The role of anti-staining lotion soap Reactive dyed or printed fabrics, after fixing, must be washed with water and soaping to remove floating color diammonium phosphite, paste and additives. The role of anti-staining agents are: 3.1 wash when floating on the surface of the fabric color has directed adsorption; 3.2 by lowering the interfacial tension, penetration into not fixing dyes and fibers and weaken the fiber does not dye fixation on the adhesion; 3.3 so that is not fixed by mechanical action with dye from the fiber loss; 3.4 If the anti-staining agent and the floating fibers dye affinity than the affinity of the floating dye, and has a colloidal nature, anti-staining agent can float down the fiber off-color dye dispersion in the wash ammonium phosphite water, the formation of a stable suspension dispersion; 4.5 strong anti-staining agent complex, decentralized power so that floating dye dispersed in wash water was not re-staining in the fiber; 4.6 anti-staining agent of weak cation and anion binding floating dye, Ershi not re-floating dye staining polyphosphoric acid fiber; 4.7 Anti-staining agent treatment-resistant fabric to prevent stains and wash fastness superb. 4. Dyes used Staining Soap detergent raw materials Soaping's main purpose is not to remove the dye fixation and hydrolysis of dyes. Would like to focus on cleaning is not available when the dye fixation temperature for soaping treatment, but will also lead to the internal fabric dye to spread the negative effects of infiltration. In addition, the higher the dye concentration, the greater the adsorption paste, dyes, paste and fiber affinity, Mercaptobenzothiazole the more difficult to thoroughly cleanse. Therefore, we must use to prevent further contamination of the efficient soaping soaping agent for processing. Market re-contamination of soap lotion products are everywhere, but the result was mixed, the key is the raw material for soap lotion and chemical composition. Currently raw materials: 4.l prevent absorption PPA and staining, to prevent dye transfer.LYQ
