Although the commonly used bis amino silicone softener has a good softness effect, but the whiteness, water absorption, easy decontamination are poor, and become serious with the increase of the amino functional group in the polymer. In order to improve these shortcomings, the type and number of amino functional groups can be changed to achieve. Changing the types of amino functional groups is mainly to change the primary amine group into secondary amine group or tertiary amine group, such as N-propylcyclohexylamine (secondary amine) and N-propylpiperazine (tertiary amine) modified silicone softeners have been developed and applied to fabric finishing. Such softeners can reduce yellowing during baking, and silicone softeners with bibomine functional groups have less hydrophobicity, but give the texture a dull feel. Mainly used for soft finishing of bleached and light colored fabrics. In addition, in order to obtain ultra-smooth feel, the two ends of dimethylsiloxane macromolecules are modified with amino end, which can form a very neat directional arrangement on the fabric, so as to obtain excellent smooth feel; If the polysiloxane is used as fabric finishing agent, it can make the fabric get better softness if part of the side chain group and both ends group are replaced by amino modification. Now the development of silicone softener is very fast, more and more varieties, the price has declined, the number of applications using silicone softener has a large increase. In addition to all kinds of silicone softener, there are epoxy modified, amide modified, carboxyl modified silicone softener.
