Problems solved by technology

The color-fixing agents currently on the market for color-fixing treatment all contain formaldehyde, which cannot meet people's needs for environmental protection, especially for infants and young children's clothing. It is necessary to ensure bright colors, that is, good color-fixing effects, and no pollution. Infant and Toddler Health
The preparation method of existing color-fixing agent all adopts simple polymerization method basically, is nothing more than to do corresponding improvement to the reaction condition of polymerization, the consumption amount of gained color-fixing agent is higher when fixing color, and color-fixing temperature is higher, color-fixing The time is longer, which makes the production cost higher, and the wet rubbing fastness needs to be improved

Abstract

The invention discloses a preparation process of environment-friendly color fixing agent. The preparation process includes the steps of firstly, heating one third formula amount of triethylene triamine to 70-80 DEG C, dropwise adding formula amount of acrylate, allowing for reaction for 2-3 hours, respectively adding formula amount of initiator and gadoleic acid comonomer, and controlling the temperature at 50-60 DEG C to complete polymerization reaction so as to obtain product A; secondly, heating two thirds formula amount of triethylene triamine to 90-100 DEG C, dropwise adding formula amount of epoxy propane, fast lowering the temperature to be below 40 DEG C, keeping the low temperature for reaction for 4-6 hours to obtain product B; thirdly, mixing product A and product B, adjusting pH to 2-3, and adding water until solid mass fraction reaches 60-65%. Compared with the color fixing agent obtained by direct polymerization reaction, the color fixing agent is better in color fixing effect, fastness to wet rubbing can be increased by one level, the defect that activated dye is poor in fastness to wet rubbing can be well overcome, and better soaping fastness and perspiration fastness are achieved.

Description

technical field [0001] The invention relates to a color fixing agent, which belongs to the field of printing and dyeing. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and health, the production of many existing dyes and chemicals has been banned internationally, and the requirements for color fixing agents have also been challenged. The color-fixing agents currently on the market for color-fixing treatment all contain formaldehyde, which cannot meet people's needs for environmental protection, especially for infants' clothes. It is necessary to ensure that the color is bright, that is, the color-fixing effect is good, and it must be pollution-free. The health of infants and young children. The preparation method of existing color-fixing agent basically all adopts simple polymerization method, nothing more than is to do corresponding improvement to the reaction condition of polymerization, the consumption amou...
