摘要： Disclosed are multicomponent fibers wherein at least one component forms an exposed surface on at least a portion of the multicomponent fiber which will permit thermal bonding of the multicomponent fiber to other fibers. The multicomponent fibers comprise two poly(lactic acid) polymers with different L:D ratios which provide biodegradable properties to the multicomponent fiber yet which allow the multicomponent fiber to be easily processed. The multicomponent fiber is useful in making nonwoven structures that may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.

摘要： A novel synthetic fiber is disclosed including a first component of an aliphatic polyester polymer, a second component of a multicarboxylic acid, an admixture of the first component aliphatic polyester polymer and the second component multicarboxylic acid to form an unreacted specified thermoplastic composition, and melt blending the unreacted specified thermoplastic composition in an extruder or a mixer. The second component multicarboxylic acid lubricates the extruder and provides a nucleating agent for crystallizing the specified thermoplastic composition to form a mean crystal size less than about 120 Angstroms. Fiber composed of the specified thermoplastic composition has a mean crystal size less than about 120 Angstroms. The fiber has a glass transition temperature (Tg) less than about 55° C. In one aspect, a first component of polylactic acid and a second component of adipic acid provide synthetic fibers in a nonwoven structure used in a biodegradable and compostable disposable absorbent product for the absorption and removal of body fluids.

摘要： Disclosed is a thermoplastic composition comprising an unreacted mixture of an aliphatic polyester polymer as a continuous phase, polyolefin microfibers as a discontinuous phase encased within the aliphatic polyester polymer continuous phase, and a compatibilizer for the aliphatic polyester polymer and the polyolefin microfibers. The multicomponent fiber exhibits substantial biodegradable properties and good wettability yet is easily processed. The thermoplastic composition is useful in making nonwoven structures that may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
