Silicone is widely used in the textile industry, and its unique properties bring a variety of excellent finishing effects to textiles. The following is a detailed summary of the application of silicone in the textile industry:

I. Application of defoaming agent
1. Defoaming and anti-foaming effect
Application scenario: In the process of textile production and processing, the presence of foam will have an adverse effect on product quality and production efficiency. Therefore, silicone defoaming agents are widely used to eliminate or inhibit these foams.

Advantages: Silicone defoaming agents have been widely used in the textile industry due to their low toxicity, antioxidant, and strong foam breaking ability. Especially in the process of textile slurry, printing and dyeing, it has a small amount of use, good effect, and is harmless to organisms, which can reduce pollution and does not affect color fastness.

II. Application of softening finishing agent
1. Softness improvement
Principle: Silicone softener uses silicone oil as the main component, and combines with textile fibers through physical or chemical action to give textiles a soft and smooth feel.
Development history:
First generation: polydimethylsiloxane (methyl silicone oil), although it can give fabrics softness, but poor washing resistance.
Second generation: hydroxy silicone oil, by cross-linking with fibers to form a protective film, improves softness and washing resistance.
Third generation: polyether modified amino silicone oil, in addition to softness, also has excellent hygroscopicity, but may have yellowing phenomenon.
Fourth generation: block modified silicone oil, which has significantly improved in softness, water resistance, elasticity and hydrophilicity, has become the mainstream of the market.

2. Practical application
Fabric feel: Modified silicone oil makes fabrics feel soft and smooth by reducing the friction coefficient between fibers.
Function improvement: Silicone softener can also give fabrics multiple properties such as water repellency, anti-fouling, anti-shrinkage and anti-wrinkle, thereby improving the application value of textiles.
