Fabric color fixing agent and preparation method of fabric color fixing agent

Abstract

The invention provides a fabric color fixing agent. The fabric color fixing agent consists of the following components in parts by weight: 8-10 parts of quaternized carboxymethyl chitosan, 4-6 parts of epichlorohydrin, 1-2 parts of acetic acid, 4-6 parts of dicyandiamide and 50-60 parts of distilled water. The invention also provides a preparation method of the fabric color fixing agent. The preparation method comprises the following steps: mixing all the components in a mixing ratio to obtain a mixture, heating the mixture to 60-65 DEG C, evenly stirring the mixture, and cooling the mixture to normal temperature, thereby obtaining the fabric color fixing agent. For a fabric treated by the fabric color fixing agent, the staining of soaping reaches grades 3 to 4, the discoloration reaches grades 4 to 5 and the fastness to wet rubbing reaches grade 3.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, and more specifically relates to a fabric color fixing agent. Background technique [0002] In the weaving process of fabrics, although some dyes can dye brighter colors, due to the poor fastness to wet treatment, the phenomenon of fading and color sticking is more serious, which not only makes the appearance of the fabric itself old, but also dyes from the already dyed. It will fall off from wet fibers and stain white or dyed fibers of other colors; clothes of different colors will stain each other and match colors during washing. Therefore, in the dyeing process, it is necessary to add a color-fixing agent to enhance the fastness of the dye. Contents of the invention [0003] The invention provides a fabric color-fixing agent, and therefore, the invention also provides a preparation method of the fabric color-fixing agent. [0004] The invention provides a f...
