Abstract: The invention provides spandex having an initial CIE whiteness of at least about 95 as measured by AATCC Test Method 110-1994, the spandex comprising an optical brightener selected from the group consisting of an oxazole, a biphenyl, a coumarin, a stilbene, a pyrazolene, a rhodamine, and a fluorescein, or a combination of such members, and an ultraviolet screener selected from the group consisting of a triazine, a benzotriazole, an oxalanilide, a benzophenone, and a bismalonate, or a combination of such members.

Abstract: A binder system for applying microcapsules to textile materials includes microcapsules in a binder composition. The binder composition includes: (i) a component selected from the group consisting of: an alkoxylated fatty acid amide, alkyl sulfonate salt, an amino-silicone softener, and mixtures thereof; an (ii) a component selected from the group consisted of: a global type wrinkle resistant resin, an imidazole type wrinkle resistant resin, a cationic polyamide, a curable silicone resin, a polyurethane resin, and mixtures thereof. Methods for making the binder system as well as methods for applying the binder system to textile materials are also provided.
