Silicone oil usually refers to a linear polysiloxane product that maintains a liquid state at room temperature, and is generally a colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Their molecular weight is not high, and they are in a fluid state at room temperature, so they are usually called silicone oils. It is generally not simply used, but made through a special formula, and is often used as an auxiliary material to produce a certain effect.

The role of silicone oil in the textile industry

Silicone oil can be used as fabric softener, lubricant, waterproofing agent, finishing agent and so on in the textile and garment industry. In order to meet the high-level needs of textiles, chemical product manufacturers are also constantly developing silicone oils that can be used in the same bath with various functional additives such as waterproofing agents, flame retardants, antistatic agents, and color-fixing agents, and have good hand feeling. In addition, in order to improve the performance of fabrics, there are also silicone products that can be used in the same bath as dyeing, silicone oil for cotton with a cool feeling, silicone products that can improve the fabric handle, and can give fabrics excellent darkening effect and storage stability. Good, does not affect color fastness, good hand feeling silicone darkening agent, etc. In addition to being used as an additive in textiles to realize the functionalization of textiles, silicone products will also be applied to other fields in textiles, such as the combination of silicone and polyurethane to form a fabric coating; the polymerization of silicone and acrylic to form fabric printing; organic The combination of silicon and organic fluorine forms a waterproof coating on the surface of the fabric, etc.

Silicone oil can be divided into primary product and secondary product according to its processing status.

The former refers to silicone oil products before processing, including four categories: hydroxyl silicone oil, silicon-functional silicone oil, carbon-functional silicone oil and inactive modified silicone oil. Among these four categories, the first two are customarily called linear silicone oils, and the latter two are called modified silicone oils.

Secondary silicone oil products refer to products such as grease, emulsion, and solution that use silicone oil as a raw material, add thickeners, surfactants, solvents, and additives, and process them through specific processes, such as silicone grease, silicone paste, Defoamer, release agent and release agent, etc.
