I. Continuously Expanding Core Application Scenarios
Silicone oil, with its unique molecular structure (low surface tension, excellent lubricity, and chemical stability due to the Si-O chain structure), has become a key auxiliary agent in textile finishing processes. Currently, its applications have expanded from traditional softening finishing to multifunctional fields such as waterproofing, antistatic, wrinkle resistance, and flame retardancy. For example, amino-modified silicone oil, through the cross-linking reaction between amino groups and the fiber surface, can significantly improve the softness and smoothness of fabrics, and is widely used in high-end apparel fabrics; mercerized silicone oil, through its low surface energy characteristics, imparts excellent waterproof performance to outdoor sportswear while maintaining breathability. Furthermore, silicone oil products used in the same bath as dyeing can achieve a dual improvement in processing efficiency and fabric performance, meeting the demands of the fast fashion industry for high-efficiency production.

II. Technological Iteration Driving High-End Transformation
As the textile industry upgrades towards green and intelligent manufacturing, silicone oil products are undergoing functional innovation. High-viscosity, low-ammonia-value amino silicone oils, through optimized molecular structure, solve the problems of yellowing and poor wash resistance of traditional products, making them suitable for infant textiles with extremely high color fastness requirements. The development of bio-based silicone oils responds to environmental trends; their biodegradable properties reduce microplastic pollution and comply with international standards such as the EU REACH regulation. Meanwhile, nano-silicone oil technology, by reducing particle size to the nanoscale, enhances the penetration and adhesion of auxiliaries on the fiber surface, resulting in more durable finishing effects and supporting the research and development of functional textiles (such as intelligent temperature-controlled fabrics).

III. Market Demand Drives Industry Expansion
As the world's largest textile producer, China's textile industry revenue reached 2.4 trillion yuan in 2024, with the proportion of high-end fabrics continuing to increase. As a core material for enhancing product added value, silicone oil's market demand is growing accordingly. It is predicted that from 2025 to 2029, the output value of China's textile market will expand at a compound annual growth rate of 3.02%, driving the silicone oil market size to exceed 15 billion yuan. In the future, with the release of demand for functional textiles due to consumption upgrades, the application of silicone oil in emerging fields such as medical textiles and automotive interiors will be further broadened, forming a new growth engine.
