Abstract: The present invention provides multicomponent fibers, nonwoven fabrics and surge management layers that include multicomponent fibers that comprise a first component that comprises a blend of a first polyolefin and from about 0.1 to about 5 weight percent of an ethoxylated hydrocarbon and a second component that comprises a blend of a second polyolefin and from about 0.1 to about 5 weight percent of an ethoxylated siloxane.

Abstract: The present invention provides nonwoven fabrics that include a first level and a second level wherein the first level includes first fibers that include a polyolefin and a first amount of an additive or a combination of additives to improve wettability and the second level includes second fibers that include a second amount of an additive or a combination of additives to improve wettability wherein the second amount of an additive or a combination of additives to improve wettability is essentially zero or is less than the first amount of an additive or a combination of additives to improve wettability. In one desirable embodiment, the wettability of the fabric is temperature dependent and may decrease as the temperature decreases. Such fabrics may be useful as components in absorbent products, for example liners and surge management layers, by providing components that are wettable during an initial insult and then decrease in wettabilty as the insult cools to discourage flow back of the insult.
