Problems solved by technology

These chlorine-resistant color-fixing agents can effectively improve the chlorine-resistant color fastness of pure cotton fabrics, but do not mention the chlorine-resistant color fastness on swimsuit fabrics such as nylon and nylon spandex, and do not mention the effect on textile color change, feel and The impact of comprehensive performance on washing resistance and other aspects
In fact, for chlorine-resistant color-fixing agents, in addition to the rigid requirements of long-lasting chlorine-resistant color fastness, it is also required to have no negative impact on the original properties of textiles such as shade and handle. However, domestic reports in this regard are still rare

Abstract

The invention discloses an environment-friendly chlorine-resistant color fixing agent, and a preparation method and application thereof. The chlorine-resistant color fixing agent comprises, by mass, 35-40% of chlorine-resistant intermediates, 0.1-1.0% of chelating agent, 0.5-5% of deoxidants and the balance of water. Proper functional monomers having high reactive activity with chlorine are selected and then composited into the chlorine-resistant color fixing agent, the environment-friendly chlorine-resistant color fixing agent reacts with active chlorine preferentially, damage of the active chlorine to a dye molecule color development system is reduced, and accordingly, the chlorine water resistance and color fastness of dyed textiles are improved.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing, and relates to an environment-friendly chlorine-resistant color-fixing agent and a preparation method and application thereof. Background technique [0002] As a cheap and efficient disinfectant, chlorine is widely used in the disinfection and sterilization of tap water, swimming pool water, hospitals and other occasions. Because the dye molecules used for textile dyeing generally have poor chlorine resistance, especially sensitive color dyes such as fluorescent red and lake blue have extremely poor chlorine resistance, and are easily oxidized and destroyed by available chlorine molecules, losing their original color and affecting the appearance and style of textiles. and performance. Therefore, swimsuits, surgical gowns and other textile and clothing products that are potentially exposed to available chlorine need to be finished with chlorine resistance to improve the color fastness ...
