The application of fluorosilicone oil in the textile industry is mainly reflected in the following aspects:

1. As a fabric surface treatment agent
Fluorosilicone oil is often used for waterproof and anti-fouling finishing of fabrics, leather, etc. and has oil repellency and solvent repellency. Its unique chemical structure greatly reduces the surface energy of the treated fabric, thus having excellent waterproof, anti-fouling and oil repellency. This is of great significance for improving the durability and practicality of textiles. Specifically:

Fluorosilicone oil with an alkyl chain containing 8 to 10 perfluorinated carbon atoms can achieve the maximum waterproof and oil repellent effect.
For fluorinated silicone polymers with the same number of carbon atoms, the waterproof and oil repellent properties of straight chains are usually more effective than those of branched chains.
Fluorosilicone oil containing heptafluoroisopropoxypropyl (or ethyl) side chains, its unique T-shaped fluorine-containing structure gives the product a good fluorine shielding effect, which can be used for fabric finishing to greatly improve the water-repellent, oil-repellent and anti-fouling properties of fabrics.
Fluorosilicone oil prepared with mercaptosilicone oil and fluorinated monomers (such as fluoroacrylates) can improve its oil repellency after being used in textiles, especially fiber products.
The fluorosilicone oil obtained by reacting allyl siloxane with fluorinated mercaptan in the presence of AIBN is used for cotton fabric finishing. The finished fabric still has good water-repellent and oil-repellent effect after dry cleaning and wet cleaning.

2. As a defoaming agent for textile printing and dyeing
Fluorosilicone oil defoaming agent can be used in the textile printing and dyeing process to effectively eliminate foam and improve the quality and efficiency of printing and dyeing. Its excellent defoaming performance and chemical stability make fluorosilicone oil defoaming agent have broad application prospects in the textile printing and dyeing industry.

3. Promote technological innovation in the textile industry
The application of fluorosilicone oil has also promoted technological innovation and product upgrading in the textile industry. By introducing new materials such as fluorosilicone oil, textile companies can develop more new textiles with special functions and excellent performance to meet the market demand for high-quality and multifunctional textiles.

In summary, the application of fluorosilicone oil in the textile industry not only improves the quality and performance of textiles, but also promotes technological innovation and product upgrading in the textile industry. With the continuous development and improvement of fluorosilicone oil technology, its application prospects in the textile industry will be broader.
