Fluoroalkyl Siloxanes as Liquid-Repellent Fabric Finishes. Part 3. The Durability of the Copolymers and Comparisons with Commercially Available Finishes.
Abstract
In this report the durability of liquid repellency properties imparted to fabrics by solutions of the copolymers of fluoroalkyl-substituted silanes and non-fluorinated silanes is examined. The best available commercial finishes were examined at the same time and the results compared with those of the experimental finishes. The durability testing encompassed wear, washing, dry cleaning, and weathering. Although the siloxane copolymers wear well, they are somewhat inferior to the commercial finishes after a number of washes. Much better durability to washing was obtained when a small amount of resin was added to the finish, following the normal commercial practice. The properties found for the siloxane finishes indicate that they could be useful in some circumstances.
