Abstract:
A disposable absorbent product comprising a liquid-permeable topsheet, an absorbent structure, and a liquid-impermeable backsheet, wherein at least one of the liquid-permeable topsheet or the liquid-impermeable backsheet comprises a biodegradable nonwoven material comprising a plurality of multicomponent fibers prepared from a thermoplastic composition, wherein the thermoplastic composition comprises:a. a poly(lactic acid) polymer in a weight amount that is greater than 0 but less than 100 weight percent;b. a polymer selected from the group consisting of a polybutylene succinate polymer, a polybutylene succinate adipate polymer, and a mixture of such polymers, in a weight amount that is greater than 0 but less than 100 weight percent; andc. a wetting agent, which exhibits a hydrophilic-lipophilic balance ratio that is between about 10 to about 40, in a weight amount that is greater than 0 to about 15 weight percent,wherein all weight percents are based on the total weight amount of the poly(lactic acid) polymer; the polymer selected from the group consisting of a polybutylene succinate polymer, a polybutylene succinate adipate polymer, and a mixture of such polymers; and the wetting agent present in the thermoplastic composition.
