<p>A hydrophilic binder fiber. These fibers may be produced by co-spinning a polyolefin core material with a highly wettable aliphatic polyester blend sheath material. The highly wettable aliphatic polyester blend comprises an 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 hydrophilic binder fiber exhibits substantially improved biodegradable properties, yet is easily processed. The hydrophilic binder fiber may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.</p> |
