Abstract

The invention discloses a method for preparing novel efficient soaping agent for activated dyes. The method includes the steps of a, sequentially adding 10-25 parts of fatty alcohol polyoxyethylene (15) ether, 10-25 parts of polyvinylpyrrolidone and water into a reactor of 1000ml, heating to 30-60 DEG C, stirring for 20-40 minutes for dissolve; b, sequentially adding 3-6 parts of ethyloic-tartronic acid, 100-200 parts of copolymer of maleic and acylic acid, 50-100 parts of dodecyl polyoxyethylene (9) ether amber sulfonate, 3-6 parts of methyl glycine oxalic acid, and a certain amount of water in the solution obtained in the step a, stirring at the temperature of 30-60 DEG C for 0.5-2 hours to obtain an optimized detergent product with 20% solid content. The novel detergent prepared for the activated dyes has the advantages of good detergent washing performance and dispersing performance, stable pollution proofing capability, stable storage, safety, non-toxic, environment-friendliness and the like.

Description

Technical field: [0001] The invention relates to a novel reactive dye high-efficiency soaping agent, in particular to a preparation method of a novel reactive dye high-efficiency soaping agent. Background technique: [0002] Reactive dyes should be washed with water after dyeing to remove unfixed dyes, hydrolyzed dyes and other chemicals and various impurities on the textiles, otherwise it will affect the color fastness, vividness, feel and other wearing properties of the dyed products. There are the following washing processes in water washing: (1) the dyes in the fiber surface or inter-fiber capillary network channel solution are diluted and exchanged by the washing solution to remove them; (2) the dyes in the fiber inner channels first diffuse from the fiber channel solution to the fiber The surface, after desorption occurs, is then diluted and exchanged by the washing solution to remove it; (3) Some insoluble dye aggregates or particles on the fiber surface (formed color...
