Abstract
Abstract Fiber-treating compositions are disclosed which contain two types of organofunctional polysiloxanes, one bearing amino-functional organic groups and polyoxyalkylene groups and the other bearing either carboxy-functional organic groups or epoxy-functional groups, in addition to polyoxyalkylene groups. 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.
