Technical Field

The invention relates to a printing and dyeing auxiliary agent, in particular to a chinlon color-fixing spot-preventing agent applied to dyeing post-treatment of chinlon, chinlon/spandex, chinlon and blended fabrics and yarns thereof.

Background

Chinlon fiber, also called polyamide fiber, has many excellent characteristics, but has poor wet fastness such as washing fastness, perspiration fastness and the like after being dyed by acid dye. After dyeing, the color fixing agent added with the sulfonic macromolecular compound is combined with the amide group on the fiber to form a net structure to coat the dye, so that the wet fastness such as washing fastness can be improved. However, in the color fixing process, color fixing spots are formed due to the reasons of over high total hardness of water, residues of weak cationic auxiliaries on a dyeing cloth surface, unstable pH value of a dye bath, mechanical high shear failure and the like, and can be attached to the surface of a fabric and the wall of a dye vat randomly in a large quantity. The color fixing spots are mixed with dyes, oligomers, color fixing agents, surfactants and other substances, so that the fabric is damaged difficultly. Therefore, the color fixing stain preventing agent is added in the post-treatment process of the chinlon and the nylon/ammonia color fixing agent to effectively prevent the generation of color fixing stains.

The prior solution provided aiming at the color fixing of nylon and brocade/ammonia fabrics can only solve the problem of preventing the color fixing on one aspect, can not completely avoid the color fixing on the other aspect and can influence the color fixing fastness of the fabrics, for example, a chelating dispersant can only solve the problem of high yield of the color fixing due to the total hardness of water, a naphthalenesulfonic acid formaldehyde condensate sodium salt is used, but the effect is poor, the color fixing on the fabrics is generated, the color fixing on the fabrics can be eliminated by washing with Na ₂ CO ₃ after color fixing, but the color fastness of the fabrics is reduced, in addition, an anti-coagulant HPD has the effect of preventing the color fixing spots, but can only solve the color fixing spots generated by a leveling agent and a color fixing agent, and can not comprehensively and effectively prevent all the color fixing spots.

Therefore, the development of a chinlon fixing stain preventing agent becomes a problem to be solved by the technical personnel in the field.
