Disclosed is a thermoplastic composition that comprises a unreacted mixture of an aliphatic polyester polymer and a multicarboxylic acid. One example of such a thermoplastic composition is a mixture of poly(lactic acid) and adipic acid. The thermoplastic composition is capable of being extruded into fibers that may be formed into nonwoven structures that may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
L'invention concerne une composition thermoplastique renfermant un mélange n'ayant pas réagi d'un polymère polyester aliphatique et d'un acide multicarboxylique. Un exemple d'une telle composition thermoplastique est un mélange de poly(acide lactique) et d'acide adipique. La composition thermoplastique peut être extrudée en fibres pouvant former des structures non tissées que l'on peut utiliser dans des produits absorbants jetables destinés à absorber des liquides tels que les liquides biologiques.
