30 Jan Textile chemicals
The textile industry is spread across the globe and generates around 1 trillion dollar, It contributes around 7% of total world exports and employs around 35 million workers worldwide according to a report. Therefore the textile chemicals are in huge demand owing to the huge production of not just apparels but also rising demand for home furnishings, floor coverings, and technical textiles globally.
What chemicals are used in textiles?
Textile chemicals range from basic mixtures such as surfactants, starch, sulfonated oils, fats and some surfactants to highly specialized chemicals like flame retardants, chain sizes, biocides and water repellents.
Textile chemicals are part of essential textile processes such as yarn formation, textile lamination and coating, fabric pre-treatment, wet processing and finishing.
What are the steps in the textile process?
Textile processing – i.e. converting raw material into finished products is a complex process and involves a number of steps. From stripping, bleaching, dyeing to providing highly specialized finishes like flame retardant, every process requires the use of specialized chemicals –these specialized chemicals are known as textile auxiliaries.
With technological advancements and the development of new machinery and processes, the old range of textile auxiliaries was clearly insufficient to meet the needs of processing plants. Today, the industry demands auxiliaries with very strict control over a number of their properties for optimum performance in specific machines. In addition, there is a strong demand for environmentally friendly products. Regulatory requirements on these chemicals are also becoming increasingly stringent. Therefore, the number of specific textile auxiliaries is constantly increasing with innovation in textile processing.
What are textile auxiliaries?
At different stages of wet processing of textiles, different types of chemicals and auxiliaries are used. Although all are in fact chemicals, in practice the materials without which a process cannot be completed are called “chemicals” and other substances which facilitate or improve the performance of this process are called “auxiliaries”.
Auxiliaries are chemicals that help processing operations such as preparing, dyeing, printing or finishing to be carried out more efficiently. In some cases, these chemicals are essential if a given effect such as washing and wear, water repellent, flame retardant, aromatic finish, odor repellent, color deepening, etc. must be obtained.
What are the chemicals used in dyeing?
Dyes used in textiles are used to color the original raw material and therefore the product. Dyes can be synthetic, which means they’re scientifically made with chemicals, or natural, which means they’re made with things found in nature. The dye is usually made into textiles through a combination of water and synthetic or natural dyes. The water used for this process in textile manufacturing is immense, which has created the need for other dry treatments for dyes, but none of them are as effective as wet dyeing.
Natural dyes are made from plants and minerals and then are combined with starches and algae to make sure they match the material. Synthetic dyes are generally made from coal tar and petroleum. They vary so much because different materials require different chemicals to make the dye adhere. For example, you cannot use the same dye for leather as for cotton, due to the huge difference in material. According to their nuclear makeup, dyes can be anionic or cationic. Some types of synthetic dyes include: Acid-based dyes, Sulfur, Reactive, Azoic, Mordent, and many more.
