Abstract
The liquid repellencies imparted to fabrics by solutions of a family of ten fluoroalkyl-substituted siloxanes are described. Fluoroalkyl substituents with varying structures were employed. Both the amide function and the ether function were used to attach fluoroalkyl substituents. Five of the siloxanes were network polymers while the remaining five were the corresponding linear polymers. In general, those polymers bearing the longer straight-chain fluoroalkyl substituents and attached to the siloxane backbone with the amide group gave the best repellencies. In some cases, the longer fluroalkyl-substituted silanes could be copolymerized with nonfluorinated alkyl silanes without effecting the liquid repellencies imparted to the fabric. The durability of these copolymers to laundering, wearing and dry cleaning were examined for the most promising finishes. The use of added resin was advantageous.
