1. A nonwoven web of fibers, wherein the fibers comprise a blend comprising:at least one thermoplastic aliphatic polyester;
an alkyl, alkenyl, aralkyl, or alkaryl anionic surfactant incorporated in the polyester; wherein the surfactant is selected from the group consisting of alkyl sulfate, alkenyl sulfate, alkaryl sulfate, aralkyl sulfate, alkylalkoxylated sulfate, alkyl sulfonate, alkenyl sulfonate, alkaryl sulfonate, aralkyl sulfonate, alkylalkoxylated sulfonate, alkyl phosphonate, alkenyl phosphonate, alkaryl phosphonate, aralkyl phosphonate, alkyl phosphate, alkenyl phosphate, alkaryl phosphate, aralkyl phosphate, alkyl alkoxylated phosphate, di(C8-C18) sulfosuccinate salts, C8-C22 alkyl sarcosinate salts, C8-C22 alkyl lactylate salts, and combinations thereof; wherein the surfactant is present in a concentration sufficient to make the nonwoven web durably hydrophilic and absorbent and instantaneously wettable; and
a surfactant carrier;
wherein the fibers are 20 micrometers or less in diameter;
wherein the surfactant is soluble in the carrier at greater than 10% by weight such that the surfactant and carrier form a visually transparent solution in a 1-cm path length glass vial when heated to 150° C.
