Silicone oil usually refers to a linear polysiloxane product that remains liquid at room temperature. It is generally a colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Their molecular weight is not high, and they are fluid 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.

Generally speaking, there are three basic forms of silicone oil on the market: pure silicone oil, solution, and emulsion.

1. Pure silicone oil
Pure silicone oil has very strong stability, heat resistance, frost resistance, good storage properties, high flash point and high ignition point, and few storage and transportation problems.

2. Solution
In fact, it is often necessary to dilute the silicone oil solution, and sometimes it is desirable to add active auxiliary agents (catalysts, crosslinking agents, etc.) to the solution for storage and use. Aliphatic, aromatic or chlorinated hydrocarbons can be used as solvents as required. In special cases Only use other kinds of solvents. Generally, the concentration of polymer polysiloxane solution can only reach 35%, otherwise the viscosity will be too high.

3. Lotion
A large part of silicone oil or products containing silicone oil are made into emulsion form. Compared with solvent silicone oil, it has the advantages of low price, non-flammable, and harmless to health. Different from the solvent type, all silicone emulsions are "oil-in-water" heterogeneous systems. Its external closed phase is the water phase. Silicone oil is dispersed in the water phase in very fine droplets, and it is easy to dilute with water to the required concentration. For application, the stability of this emulsion can be achieved by making the droplets as fine as possible and the stabilizing effect of the emulsifier.

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-end 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 fixing agents, with good feel. In addition, in order to improve the performance of the fabric, there are also silicone products that can be used in the same bath with dyeing, silicone oil for cotton with a cool feeling, silicone products that can improve the feel of the fabric, and can give the fabric an excellent deepening effect and storage stability. Good, does not affect the color fastness, good hand feeling silicone deepening agent, etc. In addition to being used as additives in textiles to realize the functionalization of textiles, silicone products will also be applied to other areas in textiles, such as the combination of silicone and polyurethane to form textile coatings; the polymerization of silicone and acrylic acid to form textile printing; organic The combination of silicon and organic fluorine forms a waterproof coating on the surface of the fabric.
