Abstract

The invention discloses a preparation method for a pad-dyeing high-temperature-resistant acidic dye-fixing agent and a dye-fixing agent prepared by the preparation method. The preparation method comprises the following steps: mixing, heating and stirring vinyl acetate and benzoyl peroxide, dropwise adding a triallylamine solution while stirring, cooling and stirring after dropwise adding; adding salicylic acid, heating and stirring; dropwise adding piperidine at a 20-minute moment, heating and stirring after dropwise adding, and cooling to the room temperature to obtain the dye-fixing agent. The preparation method is simple in preparation process; the dye-fixing agent obtained by mutual action of the components does not contain formaldehyde or APEO; positive ion groups in dye-fixing agent molecules are statically combined with negative ion groups in dye to form insoluble color lakes on the surface of fabric to seal water solvent groups of the dye, so that washing fastness resistance of the dyeing fabric is improved. The pad-dyeing high-temperature-resistant acidic dye-fixing agent has the characteristics of being high in dyeing firmness, improving washing fastness and dry-wet firmness, being resistant to high temperature, being environmentally friendly, and being free of pollution, is low in production cost, is stable in performance, is suitable for industrial production, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a preparation method of a heat-resistant acid color fixing agent for pad dyeing and the obtained color fixing agent. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for textiles has also increased, and the requirements for textiles have also become higher and higher, such as the requirements for bright colors and good color fastness of textiles. As a representative of the modern dye industry, reactive dyes are favored by the printing and dyeing industry for their bright color, complete chromatogram, economical process, simple operation, good level dyeing, and low price. However, reactive dyes have their own shortcomings that are difficult to overcome. When dyeing deep and thick colors, its color fastness is relatively poor. It is an important measure to improve the color fastness by finishing wit...
