What are the textile printing and dyeing additives

Textile printing and dyeing auxiliaries refer to chemicals added in the production and processing of textiles to improve certain properties. Common textile printing and dyeing auxiliaries include the following categories:

Dye additives: Dye additives can improve the affinity and permeability of dyes on textile fabrics, promote uniform coloring of dyes, and increase dyeing speed and rate. There are many categories of dye additives, including acid dye additives, vat dye additives, and disperse dye additives.

Dispersant dye: Dispersant dye, also known as dispersant, is a chemical substance that increases dispersion. Dispersal dyes can disperse water-soluble dyes evenly in the dye bath, avoiding staining spots and color differences caused by dye concentration. There are also many types of dispersants, such as anionic dispersants, cationic dispersants, and non ionic dispersants.

Fixing agent: Fixing agent is a chemical that can form chemical bonds between dye molecules and fibers, thereby fixing the dye onto the fibers. The types of color fixing agents include cationic, anionic, neutral, etc. Commonly used include metal salts, phenolic resins, polymers, etc.

Effect enhancer: Effect enhancer can change the interaction between coloring substances and fibers, improving the brightness and clarity of colors. Common effect enhancers include brighteners, leveling agents, catalysts, etc.

Antioxidants: Antioxidants are a type of chemical substance that can counteract oxidative reactions. In the process of textile production, they can prevent fibers from being oxidized and degraded, extending the service life of textiles. Commonly used antioxidants include sodium hypophosphite, anthraquinone, dicarboxylic acid, etc.

Overall, there are many types of textile printing and dyeing additives, and it is necessary to choose appropriate additives based on the specific situation and comply with relevant safety operating procedures.
