Abstract

The invention provides a cationic formaldehyde-free color fixing agent and a preparation method thereof. The preparation method includes step (1) of placing a certain amount of water and chitosan quaternary ammonium salt into a four-port reaction bottle, and under the protection of nitrogen, heating with oil bath to 85-120 DEG C; step (2) of respectively adding dropwise a mixed solution of 6-allyl-amino-n-hexyl-trimethylammonium chloride, a sugar-containing monomer and water, additionally adding dropwise an initiator solution with a mass concentration of 1% to 3%, wherein the initiator solution is prepared from an initiator and water; step (3) of controlling the adding of the mixed solution of the 6-allyl-amino-n-hexyl-trimethylammonium chloride, the sugar-containing monomer and the waterand the initiator solution to be completely at the same time, wherein the dropwise adding time is 3-6 h; step (4) of keeping the temperature to continue the reaction for 1-3 h after the dropwise adding, and performing cooling and discharging to obtain the color fixing agent.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, in particular to a cationic formaldehyde-free color fixing agent and a preparation method thereof. Background technique [0002] Cotton fabric fiber has become one of the most popular fabric fibers due to its superior wearing performance and environmental protection. It is widely used because of its good hygroscopicity, warmth retention, comfort and soft feel, as well as the characteristics of cleaning, health care, degradable recycling and so on. The current fabric dyeing is mainly based on reactive dyes, because reactive dyes have many advantages such as complete color spectrum, bright color, low price and convenient use. However, because the dye contains hydrophilic groups and the particle size of the dye can affect the soaping fastness of the dyeing, resulting in unsatisfactory rubbing fastness, so the fabric must be treated with a color-fixing agent after dyeing to improve the c...
