Classification And Application Of Functional Textile Auxiliaries

Functional textile auxiliaries refer to chemical substances that are applied to textiles to improve their performance, durability, appearance, and other functional properties. These auxiliaries can be classified into various types based on their chemical composition and the intended function.

Here, we will discuss the classification and application of functional textile auxiliaries.

1.Softeners

Softeners are used to improve the feel of the textile by reducing the stiffness and increasing the smoothness. Softeners can be classified into three categories: nonionic, cationic, and anionic. Nonionic softeners are compatible with a wide range of fibers, while cationic and anionic softeners are suitable for specific types of fibers. Softeners are widely used in the production of apparel, beddings, and other textile products.

2.Water-repellent agents

Water-repellent agents are used to make textiles water-resistant or waterproof. These agents can be divided into two categories: hydrophobic and hydrophilic. Hydrophobic agents repel water from the surface of the textile, while hydrophilic agents allow water to pass through the textile while preventing it from soaking in. Water-repellent agents are widely used in outdoor clothing, umbrellas, and tents.

3.Flame retardants

Flame retardants are used to make textiles resistant to fire. They can be classified into two categories: reactive and additive. Reactive flame retardants are chemically bonded to the fibers, while additive flame retardants are applied as a coating or finish. Flame retardants are widely used in industrial textiles, such as curtains, upholstery, and protective clothing.

4.Antimicrobial agents

Antimicrobial agents are used to prevent the growth of microorganisms on textiles, including bacteria, fungi, and viruses. They can be classified into two categories: natural and synthetic. Natural antimicrobial agents are derived from plants or animals, while synthetic agents are manufactured in the laboratory. Antimicrobial agents are widely used in medical textiles, such as hospital gowns, beddings, and surgical drapes.

5.UV-absorbing agents

UV-absorbing agents are used to protect textiles from the harmful effects of UV radiation. They can be classified into two categories: organic and inorganic. Organic UV-absorbing agents are derived from organic compounds, while inorganic UV-absorbing agents are derived from minerals. UV-absorbing agents are widely used in outdoor clothing, swimwear, and protective gear.

6.Antistatic agents

Antistatic agents are used to prevent the buildup of static electricity on textiles. They can be classified into two categories: internal and external. Internal antistatic agents are incorporated into the fiber or yarn, while external antistatic agents are applied as a finish. Antistatic agents are widely used in textile products, such as carpets, upholstery, and clothing.

In conclusion, functional textile auxiliaries play a vital role in the textile industry by improving the performance, durability, and appearance of textiles. They can be classified into various types based on their chemical composition and intended function. Each type of functional textile auxiliary has its unique application in the textile industry, and their usage continues to grow as technology advances.
