What are the classification of dyeing and finishing auxiliaries?
1, the removal of auxiliaries fiber or fabric to improve the processing efficiency of additives or to make the process more smoothly, and in the subsequent process will be removed, so as not to affect the progress of the process, this additive Known as removal of additives, such as textile slurries, chemical fiber oil and so on.
There are generally four types of methods. First, according to the auxiliary agent in the fiber whether the long-term retention of additives in the fiber on the existence of two cases, according to these two cases, the textile dyeing and finishing auxiliaries can be divided into two kinds of additives and retention additives
Many types of textile auxiliaries, the composition of complex, different performance purposes. In order to better understand and use, it is necessary to classify them. Different angles, there are different classification methods.
Second, according to the composition of raw materials according to raw materials According to the composition of raw materials, textile auxiliaries can be divided into surface active additives and non-surfactant agent two categories: 1, surfactant auxiliaries textile dyeing and finishing auxiliaries A large part of the composition by the surfactant, accounting for about half of all textile auxiliaries. Part of which is itself pure surfactant, more is containing surfactants and their complexes, such as emulsifiers, wetting agents, detergents and so on.
2, the retention of additives is treated, the agent mechanically precipitated on the fiber or with the chemical reaction and combined in the subsequent process is no longer removed, resulting in more lasting many effects, many finishing agents and flame retardants, Softener and so are a retention agent.
