Abstract
A nonwoven structure or web is provided where a binder fiber contains an energy receptive additive. The fiber provides rapid heating when subjected to dielectric energy such as radio frequency or microwave radiation. The energy receptive additive has a dielectric loss of at between 0.5, preferably 0.1 and most preferably 5, and 15.
Claims24
A nonwoven structure comprising binder fibers and having a center and an outer surface wherein said structure has less than 5 times more oxidation at said outer surface than at said center.
The nonwoven structure of claim 6 wherein said electromagnetic radiation is microwave radiation.
A nonwoven structure comprising superabsorbent, pulp, and binder fiber, said binder fiber having energy receptive additive in an amount between 5 and 15 weight percent and having a dielectric loss of at least 0.5, wherein said structure has been subjected to microwave radiation to activate said binder fiber and bond said structure.
