The Core Role of Silicone Oil in Textile Processing
Silicone oil, with its unique chemical structure, is widely used as a multifunctional auxiliary agent in the textile industry. The high bond energy of the Si-O bonds in its molecular chain endows silicone oil with excellent thermal stability and chemical inertness, allowing it to maintain stable performance in high-temperature processing environments. In the finishing stage of textiles, silicone oil is uniformly adhered to the fiber surface through padding, spraying, or coating processes, forming a nanoscale protective film that significantly improves the physical properties and wearing experience of the fabric.

Comprehensive Enhancement of Fabric Performance by Silicone Oil
Softness and Smooth Hand Feel: Amino-modified silicone oil forms hydrogen bonds with the hydroxyl groups on the fiber surface through its side-chain amino groups, giving the fabric a silky feel. For example, after pure cotton fabric is treated with amino silicone oil, its bending stiffness decreases by 40%-60%, and its coefficient of friction drops to below 0.1, achieving a soft effect similar to silk.
Functional Finishing: Hydrogen-containing silicone oil, through hydrosilylation reactions, can be used in the same bath with functional auxiliaries such as waterproofing agents and flame retardants, imparting waterproof, stain-resistant, and antistatic properties to fabrics. Hydrophilic silicone oils incorporate polyether segments through molecular design, enhancing moisture absorption while maintaining softness, resulting in a moisture permeability of over 5000 g/(m²·24h) for sports fabrics.
Processing performance optimization: As a lubricant, silicone oil reduces the coefficient of friction between sewing thread and fabric, decreasing thread breakage; as an antifoaming agent, it inhibits foam formation during dyeing, improving dye utilization; as a release agent, it prevents fabric from sticking to rollers, improving production efficiency.


Technological iteration and industry trends: With the textile industry moving towards high-end products, silicone oil technology exhibits two major trends: first, multifunctional integration, combining antistatic, antibacterial, and cooling functions through molecular design; second, environmental friendliness, with water-based silicone oil systems replacing solvent-based products, and bio-based silicone oils reducing carbon emissions. For example, G800 hydrophilic and smooth silicone oil has achieved "multi-effect in one agent" and is widely used in infant and toddler clothing.
