Abstract

The invention discloses a formaldehyde-free color fixing agent. The agent is prepared from the following raw materials in parts by weight: 15-23 parts of ammonium persulfate, 11-19 parts of succinic acid, 7-15 parts of ethoxylated lauryl alcohol sulfates and 1-5 parts of cyclohexyl methyl ketone. The formaldehyde-free color fixing agent is prepared by the following steps of mixing and grinding the ammonium persulfate and the cyclohexyl methyl ketone, adding an ethoxylated lauryl alcohol sulfates solution, heating the solution to 72 DEG C and carrying out stirring treatment at the temperature for 53 minutes; adding a succinic acid solution and stirring at 80 DEG C for 38 minutes; and heating the solution to 92 DEG C and stirring at the temperature for 45-50 minutes. The prepared formaldehyde-free color fixing agent can be crossliked and combined with active groups of dyes and fiber molecules, the affinity of the dyes to water is reduced, the wet-treatment fastness of soaping, staining and the like of dyed fabric is improved. The adopted raw materials are simple, wide in sampling and low in production cost; the formaldehyde-free color fixing agent is free of formaldehyde and environmentally friendly; the quality of the fabric is improved; and the environmental protection requirements and the health requirements of people are met.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to an formaldehyde-free color fixing agent. Background technique [0002] In the fabric dyeing process, in order to maintain the firmness of the color, people use a color-fixing agent at the end of dyeing. The existing color-fixing agent is a dicyandiamide structure, which will cause serious changes in hue during the color-fixing process of medium and high-temperature dyes; in addition, this type of color-fixing agent will affect the color of the fabric Fastness to sunlight and sweat. Especially the wet rubbing fastness and soaping staining fastness when dyeing dark colors, the light fastness and chlorine bleaching fastness when dyeing light colors are all unsatisfactory. Generally used reactive dye fixing agents basically contain formaldehyde, such as dicyandiamide and formaldehyde-condensed resins as color fixing agents. This type of color fixing agent ha...
