Common Textile Auxiliaries For Textile Auxiliaries
Apr 24, 2018

Textile dyeing and finishing auxiliaries play a very important role in the process of textile processing. Although they are not used, they have an important role in the process of textile processing, and sometimes even play an indispensable role.

1, shorten the processing cycle or reduce processing procedures, save processing time and improve processing efficiency.

2, reduce energy consumption, save energy and reduce costs.

3, reduce the pollution of the three wastes and improve the quality of the environment.

4, improve the printing and dyeing effect and the appearance and inner quality of the fabric.

5, endow textiles with some special functions and effects, improve their performance and value added.

Classification of textile dyeing and finishing auxiliaries

There are many kinds of auxiliaries for textile dyeing and finishing, which are complex in composition and different in properties and uses. In order to better understand and use, it is necessary to classify them. Different points of view, there are different classification methods. There are generally four kinds of eight kinds of methods.

1. Classification of auxiliaries on fiber for long term.

There are two situations for the retention of auxiliaries on fibers. According to these two situations, textile dyeing and finishing auxiliaries can be divided into two categories: removal AIDS and retention auxiliaries.

1. The removal of the auxiliaries fiber or fabric can improve the processing efficiency or make the process more smooth after treatment with auxiliaries. In the following process, it should be removed so as to avoid the effect of the post process, which is called the removal agent, such as textile size, chemical fiber oil, etc.

2, the retained auxiliaries are processed, and the additives are mechanically precipitated on the fiber or combined with the chemical reaction, and are no longer removed in the subsequent process. Many lasting effects are produced. Many finishing agents, flame retardants and softeners are all retention aids.

Two. Classification of raw materials according to the constituent auxiliaries

According to the composition of raw materials, textile auxiliaries can be divided into two categories: surface active agents and non surfactant additives.

1. A large proportion of textile auxiliaries for surfactant auxiliaries are made up of surfactants, which account for more than half of all textile auxiliaries. Some of them are pure surfactants, which contain more surfactants and their compounding agents, such as emulsifiers, wetting agents and detergent.

2. Non surface active agent additives such as polymer or other organic and inorganic substances, such as resin finishing agent, flame retardant, fluorescent brightener, etc. are not contained in this kind of dyeing and finishing auxiliaries.

Each major category can be divided into several small categories, such as surfactant additives as anionic surfactants, cationic surfactant auxiliaries, amphoteric ionic surfactants and non ionic surfactants.

Three. Classification according to form

Textile dyeing and finishing auxiliaries can be classified into two categories: liquid products and solid products. Liquid products can also be divided into water soluble, emulsion type and solvent type. Liquid products are easy to deploy, accurate and convenient to use. Therefore, textile dyeing and finishing auxiliaries are mostly liquid products. In recent years, with the improvement of environmental requirements and the strict requirements for safety and fire protection, the proportion of water-soluble and emulsion type in liquid products is increased, the solvent type products are reduced, and the solid products are mostly granular or flaky, which are characterized by easy transportation and storage.

Four, classification according to the application of auxiliaries

The principle of classification is to classify the textile auxiliaries according to their processing procedures. This classification method also has several different classification principles according to the different boundaries of the process.

A a coarse division of textile dyeing and finishing auxiliaries is divided into two categories: textile auxiliaries and dyeing and finishing auxiliaries.

B is divided into five categories: textile auxiliaries, pretreatment auxiliaries, dyeing auxiliaries, printing auxiliaries, and finishing auxiliaries.

C is divided into three categories, namely, pre-treatment auxiliaries (including textile auxiliaries), dyeing auxiliaries and finishing auxiliaries, between the first two. Each category is further subdivided into several sub categories, such as levelling agents, dispersants, fixing agents, fluorescent brighteners, pigment printing auxiliaries, etc.
