Problems solved by technology

Since the reactive dye has a water-soluble group and cannot fully react with the fiber during the dyeing process, the dye will be hydrolyzed and the covalent bond between the dye and the fiber will be broken during the washing and use process, resulting in decolorization of the fabric and the appearance of the fabric.

Abstract

The invention provides a fabric color fixing agent. The fabric color fixing agent consists of the following components in parts by weight: 4-6 parts of sodium silicate, 8-10 parts of epichlorohydrin, 9-11 parts of acryloyl chloride, 2-3 parts of octadecyl dimethyl amine and 30-35 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 sodium silicate, epichlorohydrin and distilled water according to a mixing ratio, slowly heating to 50-55 DEG C under a stirring condition, adding acryloyl chloride and octadecyl dimethyl amine according to a mixing ratio, heating to 60-65 DEG C, stirring for 2-3 hours, and cooling to normal temperature, thereby obtaining the fabric color fixing agent. Compared with the prior art, the fabric color fixing agent has a very good color fixing effect on the dyed wool fabric and just slightly affects the shade of the fabric.

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] Cotton fabrics are mostly dyed with reactive dyes. Since the reactive dye has a water-soluble group and cannot fully react with the fiber during the dyeing process, the dye will be hydrolyzed and the covalent bond between the dye and the fiber will be broken during the process of washing and use, resulting in decolorization of the fabric and a poor appearance. Obsolete, and even stained. In order to improve the color fastness of the fabric, the fabric is often subjected to color-fixing treatment. Contents of the invention [0003] The invention provides a fabric color fixing agent. [0004] The invention provides a fabric color fixing agent, which is composed of the following components in parts by mass: 4-6 parts of sodium silicate, 8-10 parts of epichlorohydrin, and 9...
