Textile auxiliaries are the materials used in textile production. These substances are either synthesized or derived from natural resources and are added to the final products to make them more suitable for usage. Basically they are considered as non-toxic and biodegradable. There are several types of such auxiliaries available in the market, which include paper, cotton, polyester, nylon, silk, wool, jute, olefin, crochet, Merino wool, rayon and polypropylene. Each of them has their own specific purpose and uses, so that it is very important to know the exact type of auxiliaries to be used in a certain textile production line before commencing the process.
Let's take a look at different textile auxiliaries in detail:
Surfactants - These are basically foam forms of starch that is added to fabrics before weaving in order to create water resistance. The basic function of surfactants is to keep the weft threads and fabric rolls from sliding together. These can either be natural or synthetic surfactants and are generally used in auxiliaries because they are both cost effective and versatile. Generally, Surfactants are used with all kinds of fabrics; however, textiles with a high moisture content tend to need more sandalwood based substances to provide proper adhesion.
Antioxidants - These are basically substances added to auxiliaries to protect the wefts from premature unraveling. Some of these prevent unraveling through chemical reactions, while others work by physical means like the UV light or by physical contact like contact paper. There are various types of antioxidant sold in the market today. Some are available in liquid form, while others need to be mixed with water before application. The most common types are Glucose, Melanoid X, Nitric Oxide, Sulfur Dioxide and Copper Chelate. In addition, Antioxidants are used as additives to prevent the textiles from discoloring or colorizing through interaction with sunlight, heat or other environmental factors.
Dyeing - The third type of textile auxiliaries is dyeing. It involves applying dye to a cloth that has been treated with some type of ink. After that, it is vacuumed at high speeds so that the color runs smoothly and fluoresces. The procedure is repeated several times until the desired shade is achieved. This type of dyeing is very labor intensive but this is what gives the textiles its colorful output.
Textile auxiliary products are used to complement the production process and give the best results. They are important in holding the threads together, preventing fraying and providing the final touch to the fabric. Several companies in the market are focused on development and launch of new products. For instance, in January 2021, Rudolf Group, the German company specialized in chemical products, predominantly textile auxiliaries, products for textile care as well as construction chemicals, launched Ruco-Dry BIO CGR and Ruco-Dry BIO NPE, two distinctive product propositions entirely manufactured from natural sources that do not compete with human and/or animal nutrition.
