Abstract

A preparing method of a sensitive color fixing agent and the fixing agent are disclosed. During preparation, methyl ethyl ketone peroxide and a 6-hydroxy-2-naphthoic acid solution are mixed, heated and stirred; dimethylformamide is added into the mixture; the mixture is heated and stirred; then a tris(nonylphenyl)phosphite solution is added into the mixture; and the mixture is stirred at 110-112 DEG C for 20-25 min, then stirred at 65-70 DEG C for 50-55 min and cooled to room temperature to obtain the fixing agent. Under interactions of raw materials, the fixing agent has advantages of high dyeing fastness, capability of significantly increasing dry and wet rubbing fastness and water-washing color fastness, and the like. Hue changes do not occur substantially during color fixing of dye for sensitive colors such as turquoise blue and cobalt blue. The fixing agent is free of formaldehyde and is environmentally friendly. A production process is simple. The fixing agent does not influence chlorine fastness, light fastness or perspiration fastness of dyed fabrics, influences of color fixing treatment on fabrics by the fixing agent are low, and chromatic aberration can be controlled to be the 4-5 level. Treated fabrics have good color fixing effects and an influence on hand feeling is low.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a preparation method of a color-sensitive color-fixing agent and the color-fixing agent. Background technique [0002] With the improvement of living standards and the requirements of work, social interaction and etiquette, people pay more and more attention to the appearance of external image and body shape. There are also more and more color requirements for various clothes. Among the existing dyes, reactive dyes have become the most widely used dyes in cotton fabric dyeing because of their advantages such as complete color spectrum, bright color, reasonable price and convenient use. However, after dyeing cotton fabrics with reactive dyes, its color fastness is average, especially the wet rubbing fastness and color fastness to washing after dyeing medium and dark colors are poor. Adsorbed on the fiber surface but not chemically bonded to the fiber, the...
