Mostly Amino Modified Silicones are used for textile industry as the Amino group provides better affinity to textile fibers. For further reactivity the end group of the amino silicone polymer need to be hydroxyl, methoxy, ethoxy, but if the end group is methyl group then the polymer is called as non-reactive or terminated one.
Apart from Amino Silicones there exist several other classes of textile silicones, such as, Hydrophilic Silicones, Non-Yellowing Silicones, Cross-Linking Silicones, Epoxy Silicones, Carboxy Silicones, Shear Stable Silicones, Amido Silicones and much more.
Functional Group -> Aminoethyl Aminopropyl, Amido, Glycol, Epoxy, Vinyl, Quaternary, Hydroxyl Reactive Group -> Methoxy, Ethoxy, OH, H X, Y -> Number of Monomeric Units
Silicone Softeners are Silicone Emulsions of various types of modified silicone polymers, with the help of suitable emulsifiers. Depending on particle size they may be micro or macro.
* Functional groups provide better affinity to textile fibres.
* Various functional groups change the nature of silicones from hydrophobic to hydrophilic character.
* Presence of hydroxyl as reactive group increases the reactivity with fibers as compared to terminated one.
* Conventional amino silicones give slight yellowing effect to the fabrics as compared to the other functional group silicones, which give minimal yellowing or complete    non-yellowing effect.
* Silicones can give various type of hand to the fabric, from slick to dry and from drapable to supple.
* Mostly textile silicones are transparent, which ensures that their particle size is less than 50 nm.
* Micro sized particles enhance inner softness of fibers.
* Specially modified silicones are shear stable and can be used in highly turbulent machines.
* Silicones can also give electrometric feel depending on the functional groups attached to the silicone backbone.
