About Textile Chemicals

During manufacturing, textile goes through long processes of chemical and non chemical treatments. Finishing procedure of the textile includes preparation, pretreatment, dyeing, printing and refinement of fabrics. Specialized chemicals which are used in the textile manufacturing process include biocides, water repellents and flame retardants. Other chemicals and mixture which are used include starch, emulsified oils, sulfonated oils, surfactants and waxes. There are around sixty different textile product classes which are used in yam formation, fabric, pretreatment, textile laminating, coating, finishing and some other applications.

Different processes are carried out during textile processing where different chemicals find their usage. These processes are scouring, bleaching, desizing, softening, mercerization, dyeing and many more.

• Scouring: When in their natural form, raw textile materials have many impurities such as additives, dirt and soil. These impurities are not suitable for clothing materials as they may also contain pesticides, fungicides and worm killers. The removal of these impurities is known as scouring. The process is done by adding wetting agents, alkali, chemical and non chemical materials. After the completion of this process, the fabric provides better wetting and penetration properties.

• Bleaching: To finish the cloth with white color, all natural colors need to be removed. This process of discoloring the raw textile material is known as bleaching. The process of bleaching can be classified into:
  • Oxidative bleaching: this is carried out using sodium hypochlorite, sodium chlorite or hydrogen peroxide.
  • Reductive bleaching: this is done using Sodium hydrosulphite which is a powerful reducing agent.
• Desizing: During the process of weaving, warp threads are coated with adhesive substances which are known as size. This coating is done to prevent the threads from breaking down during the weaving process. The most common sizing agents which are used include starch and its derivatives. After the completion of weaving, the size is removes and the fabric is prepared for dyeing and finishing. This process is called desizing which is done with chemicals such as acids, alkali and oxidizing agents.

• Dyeing: During the process of dyeing, large amount of dyestuff, thickening agent and water is used. Different textile chemicals such as dispersing agents, leveling agents and acid buffer are also used suing dyeing.

• Printing: The fabric gets color through the process of dyeing and it needs to get further enhanced by color designs. Different dyes are used for printing on the finished cloths which include naphthol, disperse and pigment colors and vat. They are fixed to the fiber through resins.
