NONWOVEN FABRICS COMPRISING STRATA WITH DIFFERING LEVELS OR COMBINATIONS OF ADDITIVES AND PROCESS OF MAKING THE SAME

摘要

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.
