In the textile industry, which is the oldest and most widespread industrial region in the world and our country, all natural, regenerated or synthetic based fibers and their blends are subjected to many operations from fiber to finished textile material. It is evident that due to the wide range of chemical substances used as inputs in this broad scope, the chemical substances used will be large in size and quantity. Many chemicals are used in all processes to be applied to the textile material to facilitate the process. During the production of the textile material, auxiliary materials are used to facilitate the process, make it more effective, or achieve a certain effect in all process steps from preparation of the yarn to preparation. These substances used can be grouped as "Chemical substance" and "Auxiliary substance". The term "chemical" means certain organic and inorganic acids, bases, salts, etc. used in textile processes. Materials are meant. These are chemical substances. The term & quot; auxiliary chemical & quot; refers to materials which are specially developed for textile processing and whose chemical constituents are usually kept for commercial reasons, in a mixture of more or less complexity. Auxiliary materials are too big for textiles. These materials have a decisive qualification for product quality. Because of this, virtually no finishing process in the industrial sense can be done without auxiliary substances. For a painting to be smooth, it must be taken properly from the color. It is undeniable that the fabric is adhered to the printing blanket for proper printing. The consistency and flow characteristics of the printing press must be perfect so that the contours are clearly visible in the print patterns. As can be understood from this and other simple examples, it is not possible to obtain a smooth result without the aid in all these operations. As you can see, it is inevitable to use a suitable auxiliary material for a quality product. Also, the fastness properties of the product at the time of use depend on the additives. As a result, the benefits of textile auxiliaries are huge. This means that the producers are well aware of the auxiliaries they will choose in production and that they must be carefully selected and used for quality production.
