Abstract
A disposable article including a biodisintegratable nonwoven material having improved fluid management properties. The nonwoven material may be produced using a thermoplastic composition that comprises a unreacted mixture of an aliphatic polyester polymer selected from the group consisting of a polybutylene succinate polymer, a polybutylene succinate-co-adipate polymer, a polycaprolactone polymer, a mixture of such polymers, or a copolymer of such polymers; a multicarboxylic acid; and a wetting agent. The thermoplastic composition exhibits substantial biodegradable properties yet is easily processed. The biodisintegratable nonwoven materials may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
