1 Cationic hydroxyl silicone oil emulsion
The emulsifier used in cationic hydroxyemulsion polymerization is generally quaternary ammonium salts (octadecyl trimethyl ammonium chloride reported in foreign literature), and the catalyst is ammonium hydroxide. Cationic hydroxyemulsion can be used for finishing all kinds of textiles, and has the properties of improving fabric feel, elasticity, smoothness and crisp. Another 1 of its unique advantages is that it is an ideal waterproof agent for fabrics, which can be used in combination with methyl hydrogen silicone oil emulsion. Its waterproof performance and waterproof durability can reach a very high level. It can be used as a waterproof agent for vinylon canopy canvas and waterproof of polyester card cloth.
2 Anionic hydroxyl silicone oil emulsion.
Anionic hydroxyemulsion is characterized by good compatibility in fabric finishing agent and very stable emulsion. In particular, most of the auxiliaries in textile printing and dyeing are anionic. If cationic hydroxymilk is used, it is easy to cause demulsification and bleach oil, while anionic hydroxymilk can avoid this disadvantage, so it is more popular with users and has a wide range of uses.
3 Composite Ionic Hydroxy Silicone Oil Emulsion
Although cationic hydroxymilk is the 1 kind of excellent fabric softening finishing agent, but this emulsion is not resistant to hard water, but also can not with the two hydroxymethyl dihydroxyethylene urea resin (2D) resin, catalyst magnesium chloride and anionic whitening agent in the same bath, so there are some limitations in the use. In addition, due to the poor stability of the emulsion, the silicone polymer is easy to separate from the emulsion and float on the liquid surface, commonly known as "floating oil". If in the emulsion polymerization process, the use of cationic and non-ionic emulsifier for compounding, can overcome the shortcomings of cationic emulsifier preparation of hydroxyl silicone oil emulsion, the silicone emulsion can withstand hard water, can be used with 2D resin, magnesium chloride and whitening agent VBL equivalent bath, and has good heat resistance and freezing resistance.
4 Non-ionic hydroxyl silicone oil emulsion
Non-ionic hydroxymilk has stronger adaptability and better stability than independent hydroxymilk, so many countries have vigorously studied non-ionic hydroxymilk. For example, the new UltrateX FSA produced by Swiss Ciba Jiaji Company is a non-ionic emulsion of hydroxyl-terminated polydimethylsiloxane 1 molecular weight above 200000, which is a step forward from the Dc-1111 anionic hydroxymilk produced by American Tao Kangning Company.
5 Other active groups of silicone finishing agent
In order to meet the needs of advanced finishing of various fabrics, improve the anti-oil, anti-static and hydrophilic properties of silicone finished fabrics, and make chemical fiber fabrics have many advantages of natural fabrics, silicone workers have studied the introduction of other active groups on silicone molecules such as amino, amide, ester, cyano, carboxyl, epoxy, etc. The introduction of these groups makes the silicone fabric finishing agent 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 group is suitable for anti-fouling finishing, and the flexibility is greatly improved: the introduction of cyano group has good oil resistance and the copolymer of polyoxyethylene ether and silicone has good antistatic effect. Organofluorine modified silicone has many advantages such as oil repellency, antifouling, antistatic and water repellency.Characteristics of methyl silicone oil
