Hydroxyl silicone oil emulsion can be divided into several types of emulsion, such as cation, anion, nonionic and compound ions, according to the different surfactants used.

1.
Cationic hydroxyl silicone oil emulsion
Quaternary ammonium salts (octadecyl trimethyl ammonium chloride reported in foreign literature) are commonly used as emulsifiers in cationic hydroxyl emulsion polymerization, and ammonium hydroxide is used as catalyst. Cationic hydroxyl milk can be used in various textiles after finishing. It has the properties of improving fabric handle, improving fabric elasticity and smoothness. It has another unique advantage: the ideal waterproof agent for fabrics, and the use of methyl hydrogen silicone oil emulsion, waterproof and waterproof durability can reach a very high level, which can be used as dimension. Waterproofing agent for canvas and polyester cardboard, etc.

2.
Anionic hydroxyl silicone oil emulsion
The anionic hydroxyl milk is characterized by its compatibility in fabric finishing agent, and the emulsion is very stable. Especially in textile printing and dyeing, most of the auxiliaries are anionic. If cationic hydroxyl emulsion is used, it is easy to cause demulsification and bleaching oil, and anionic hydroxyl emulsion can avoid this disadvantage, so it is more popular with users and has a wide range of uses.

3.
Composite ionic hydroxyl silicone oil emulsion
Although cationic hydroxyapatite is an excellent fabric softener, this emulsion is not resistant to hard water, and can not be used in the same bath with dimethoxylated two hydroxyvinyl urea resin (2D) resin, catalyst magnesium chloride and anionic whitening agent. In addition, because of the poor stability of the emulsion, silicone polymers are easily separated from the emulsion and float on the liquid surface, commonly known as "bleaching oil". If the cationic and non-ionic emulsifiers are used in the emulsion polymerization, the shortcomings of the cationic emulsifier for preparing hydroxyl silicone oil emulsion can be overcome. The prepared silicone emulsion can withstand hard water, and can be used in the same bath with 2D resin, magnesium chloride and whitening agent VBL, and has good heat resistance and freezing resistance.

4.
Non ionic hydroxyl silicone oil emulsion
Non-ionic hydroxyl milk has better adaptability and stability than separated hydroxyl milk, so many countries have made great efforts to study non-ionic hydroxyl milk. For example, UltrateX FSA, a new product made by the Swiss company, is a non-ionic emulsion with a molecular weight of more than 200 thousand and a hydroxyl head of two methyl siloxane. This is a step forward than the Dc-1111 anionic FSA milk of the US company.

5.
Organosilicon Finishers with Other Active Groups
In order to meet the needs of advanced finishing of various kinds of fabrics, improve the anti-oil stain, anti-static and hydrophilic properties of organosilicon-treated fabrics, and make chemical fiber fabrics have many advantages of natural fabrics, organosilicon workers have studied the introduction of other active groups such as amino, amide, ester, cyano, carboxyl and ring into organosilic molecules. Oxygen group, etc. The introduction of these groups makes silicone fabric finishing agents have special effects. For example, the introduction of amino groups into silicone molecules is suitable for shrink-proof and soft finishing of wool fabrics; the introduction of amide groups is suitable for anti-fouling finishing, and the softness is greatly improved. The introduction of cyano group has good oil resistance, and the anti-static effect of copolymers of polyvinyl oxide ether and silicone is good. Good; organofluorine modified organosilicon has many advantages such as oil repellency, antifouling, antistatic, water repellency and so on.
