Three Categories of Hydroxyl Silicone Oil Emulsion

2020/03/10

The composite ionic hydroxyl silicone oil emulsion can be used for the finishing of all kinds of textiles. It has the properties of improving the fabric handle, improving the elasticity and smoothness of the fabric, and its unique advantage is the ideal waterproof agent for the fabric, which is compatible with the methyl hydrogen silicone oil emulsion, and has high waterproof and water repellent durability. It can be used as waterproof agent for canvas of vinylon canopy, waterproof agent for polyester card cloth, etc.


The characteristics of anionic hydroxyl silicone oil emulsion are good compatibility in fabric finishing agent, and emulsion is very stable. In particular, most of the auxiliaries in textile printing and dyeing are anionic. If cationic hydroxy emulsion is used, it is easy to cause demulsification and bleaching oil, while anionic hydroxy emulsion can avoid this disadvantage, so it is more popular with users and widely used.


Cationic hydroxyl silicone oil emulsion is an excellent fabric softener, but 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, so it has some limitations in use. 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.
