In the textile industry, different auxiliary chemical agents are used in each processing step from spinning, weaving, dyeing and finishing to the finished product, depending on the properties of various fibers. These agents are used to improve textile quality, enhance processing effects, increase production efficiency, simplify processes, reduce production costs, and endow textiles with various superior application properties. These auxiliary chemicals are collectively known as textile dyeing and finishing auxiliaries.
Textile dyeing and finishing auxiliaries refer to chemicals added during the textile dyeing and finishing process to promote processing, improve efficiency, save energy, ensure quality, or impart special functions to textiles. Since textile dyeing and finishing processes are mostly carried out in aqueous systems, involving various interfacial interactions such as wetting, penetration, emulsification, and dispersion, dyeing and finishing auxiliaries contain a large number of surfactants, as well as some non-surfactant chemicals.
