Monomer

Performance characteristics

D4

The content of silicon is high, up to 37.6%. It is easy to open.

Hydrogen-containing silicone oil active polyether

Under certain conditions, the Si-H bond is easy to react with amines and dilute hydrocarbons to prepare various modified silicone oils. It gives the fabric good hydrophilicity, antistatic property, smoothness and antifouling property; synthetic silicone oil is water-soluble and can be emulsified without additional emulsifier; however, the softness of finished fabric is poor.

Characteristics of iso-active polyether 1.

Active polyether2#

It contains double bonds and hydrophilic groups. It has high reactivity and strong hydrophilicity. The water washing resistance of the synthesized softener is poor.

F-6

Under certain conditions, the Si-H bond is easy to react with amines and dilute hydrocarbons to prepare various modified silicone oils. It gives the fabric good hydrophilicity, antistatic property, smoothness and antifouling property; synthetic silicone oil is water-soluble and can be emulsified without additional emulsifier; however, the softness of finished fabric is poor.

EpoxyAE-6

It contains reactive groups and reacts with the groups of OH, NH₂ and COOH on the surface of the fibers to improve the durability, softness, waterproof and durable finishing effect of the finished fabric. It is not yellowing and has good stability to inorganic salts. The end of the fabric can be connected with hydrophilic groups.

Silane-coupled mustard

It contains strong polar amino groups, which can interact with light and carboxyl groups on the fibers.

KH-550

So that the friction coefficient between the fibers decreases, thus achieving a good finishing effect, but the finished fabrics tend to yellowish.

Silane coupling agent

The diamine coupling agent has neat molecular structure, good orientation and adsorb-ability.

KH-602

But its diamine structure is easier to oxidize, which makes the light-colored fabric yellowing seriously after finishing.

Ethylenediamine

The simplest diamine has strong alkalinity and reactivity. The finished fabric with amino silicone oil synthesized by diamine has good handle, but serious yellowing and easy cross-linking.

Two ethylamine

Amino silicone oil has low boiling point, mild reaction conditions and good handle, but its alkalinity is too weak. A small amount of alkali catalyst is needed to increase the reaction rate.
