Abstract
Abstract Fiber-treating compositions are disclosed which contain two types of organofunctional polysiloxanes, one bearing amino-functional organic radicals or carboxy-functional organic radicals or epoxy-functional radicals and the other bearing another type of organofunctional radicals selected from the same group. In addition, at least one of the organofunctional polysiloxanes bears one or more polyoxyalkylene radicals. These compositions are useful for durably treating fibers to provide several benefits such as antistatic character, moisture/perspiration absorbability, stain resistance, pliability, smoothness, crease resistance and compression recovery.
