1. An article comprising a non-woven web of fibers, wherein the fibers comprise a durable hydrophilic composition comprising a blend of:
at least one thermoplastic aliphatic polyester, wherein the thermoplastic aliphatic polyester is selected from the group consisting of one or more poly(lactic acid), poly(glycolic acid), poly(lactic-co-glycolic acid), polybutylene succinate, polyhydroxybutyrate, polyhydroxyvalerate, blends, and copolymers thereof; an anionic surfactant incorporated into the polyester, wherein the anionic surfactant is selected from the group consisting of di(C8-C18) sulfosuccinate salts, C8-C22 alkyl sarconsinate salts, C8-C22 alkyl lactylate salts, alkyl alkoxylated phosphates, and alkyl carboxylates; and a surfactant carrier, wherein the surfactant carrier is a liquid at 23° C. and is selected from the group consisting of polyalkylene glycol, polyhydric alcohols, glycerin triglcyerides, citric acid esters, aliphatic diesters and combinations thereof; wherein the composition is free of organic and inorganic fillers, and remains hydrophilic after more than 10 days at 45° C. |
