Problems solved by technology

[0002] Textiles are divided into two categories: polyester and cotton. At present, polyester is dyed with disperse dyes, and cotton is dyed with reactive dyes. These traditional processes will generate a lot of waste water, and can only be used for wet cloth coloring. They also need high temperature and high pressure environment. Directly affect the dyeing effect after dyeing. Ordinary dyestuffs have high requirements on the dyeing environment. Usually, the dyeing effect is not good, the color is easy to fade after washing, and the color of the fabric becomes lighter after repeated washing. Therefore, it is necessary to provide a durable Fabric dye composition with strong washability and preparation method thereof

Abstract

The invention provides a fabric dye composition with strong washing resistance. The fabric dye composition is prepared from the following raw materials in parts by weight: 30-40 parts of solvent, 10-15 parts of dyeing agent, 8-12 parts of stabilizer, and 3-5 parts of dispersing agent, wherein the stabilizer is a mixture being prepared from sodium polyacrylate, diphenylamine and a dye-fixing agentin a weight ratio being (1-3) to (0.5-1.2) to (3-5). The invention further provides a method for preparing the fabric dye composition with strong washing resistance. The fabric dye composition prepared from raw materials provided by the invention and the process has washing-resistant color fastness being grade V after the fabric is dyed, and has sweat strain-resistant color fastness, friction-resistant color fastness and dry-heating-resistant fastness being grade IV or higher, so that high-quality dyeing fabric is achieved.
