Fluorosilicone oil is widely used in fabric waterproof and oil-proof finishing. Its excellent waterproof and oil-proof properties enable fabrics to maintain good performance in a variety of environments. The following is a detailed analysis of the application of fluorosilicone oil in fabric waterproof and oil-proof finishing:


1. Waterproof and oil-proof principle of fluorosilicone oil
Fluorosilicone oil has a special molecular structure, and its molecular chain contains fluorine atoms and silicon atoms. Fluorine atoms have extremely low surface energy, which enables fluorosilicone oil to form a dense protective film on the surface of the fabric, which can effectively block the penetration of water and oil. At the same time, the flexibility of silicon atoms makes this protective film have good elasticity and wear resistance, and can maintain waterproof and oil-proof effects for a long time.

2. Application effect of fluorosilicone oil
Excellent waterproof performance: Fabrics treated with fluorosilicone oil can significantly improve their waterproof performance, so that the fabrics can still remain dry in rainy or humid environments.
Excellent oil-proof performance: Fluorosilicone oil can also effectively prevent the penetration of oil stains, making the fabrics less likely to be contaminated in oily environments.
Improve fabric durability: Fabrics treated with fluorosilicone oil have better wear resistance and anti-aging properties, which can extend the service life of the fabric.
Maintain the original style of the fabric: Fabrics treated with fluorosilicone oil will not change their original style, feel and color, and maintain the original characteristics of the fabric.

3. Application method of fluorosilicone oil
Padding method: Immerse the fabric in a solution containing fluorosilicone oil, and then use a roller to roll off the excess solution so that the fluorosilicone oil is evenly distributed on the surface of the fabric. This method is suitable for fabrics of various fiber types.
Coating method: Mix fluorosilicone oil with resin, cross-linking agent, etc. to make a coating agent, and then apply it to the surface of the fabric. This method is suitable for fabrics that require high waterproof and oil-proof properties.
Printing method: After mixing fluorosilicone oil with printing slurry, the mixed solution is printed on the fabric through a printing machine. This method is suitable for printed fabrics that require waterproof and oil-proof properties.

4. Environmental protection of fluorosilicone oil
Modern fluorosilicone oil products are usually prepared using environmentally friendly raw materials and processes, and have the characteristics of low toxicity and low volatility. At the same time, fabrics treated with fluorosilicone oil can be recycled and reused to achieve resource recycling, which is in line with the concept of sustainable development.

5. Precautions
Selection of fluorosilicone oil: The appropriate fluorosilicone oil should be selected according to the fiber type, purpose and waterproof and oil-proof requirements of the fabric.
Optimization of treatment process: The treatment process should be optimized to ensure that the fluorosilicone oil can be evenly distributed on the surface of the fabric and form a good protective film.
Improvement of environmental awareness: When using fluorosilicone oil for waterproof and oil-proof finishing of fabrics, attention should be paid to environmental protection and sustainability, environmentally friendly fluorosilicone oil products should be selected, and the discharge of wastewater and waste gas should be reduced.

In summary, fluorosilicone oil has broad application prospects and important application value in the waterproof and oil-proof finishing of fabrics. With the continuous development of the textile industry and the continuous improvement of people's requirements for the performance of textiles, the application of fluorosilicone oil will become more and more extensive.
