Abstract

The invention relates to a quaternary ammonium salt cationic color fixing agent and a preparation method thereof. The preparation method comprises the following steps that (1) long-chain alkyl quaternary ammonium salt, organic acid amide and water are added into a reaction vessel provided with a thermometer, an oil bath pan and a stirrer, stirring is started, and heating is started; (2) when the temperature in the reaction vessel rises to 85-120 DEG C, a mixed solution of a (methyl) acrylate monomer with amino groups, an initiator and the water is dropwise added and is dropwise added completely within 3-6 hours; and (3) after dropwise adding is completed, the temperature is continuously kept for reaction for 1-3 hours, and cooling and discharging are carried out so as to obtain the color fixing agent.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, in particular to a quaternary ammonium salt cationic color-fixing agent and a preparation method thereof. Background technique [0002] After my country's accession to the World Trade Organization, the processing requirements for textiles have become more and more stringent, especially for the detection of formaldehyde content in textiles. This also prompts printing and dyeing enterprises to transform and upgrade textiles to further meet the growing environmental protection requirements and export requirements. [0003] The formaldehyde content in printing and dyeing textiles is generally a harmful substance introduced during the dyeing and color fixing process of textiles. In the color fixing process of printing and dyeing, because the color fixing agent used will release toxic and harmful formaldehyde gas during use, resulting in product It does not meet the current environmental p...
