More Information
Summary:This invention relates to films, composites, and other compositions that can be made into articles that are disposable through dispersal into waste water under aqueous-alkali conditions and the use of such articles, made from such compositions, as sheet-like materials that have stability during use and disperse into water as a means of disposal. An alkali dispersible article comprises a sheath-core microfiber. The sheath layer comprises a hydrolytically degradable polymer, and the core layer comprises another polymer that is different than the sheath polymer. The core polymer may be a hydrolytically degradable polymer or more preferably a water soluble polymer.
