摘要：
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.
