    摘要: The present invention relates to a nonwoven web comprising a plurality of loops. At least one of said loops having a loop circumference length to loop base length ratio that is greater than about 4:1. The loops may also have a base length less than 0.5 cm and a base length less than the maximum width of the loops. The present invention also relates to articles selected from the group consisting of disposable hygiene article and wipes comprising a nonwoven web wherein at least one region of the nonwoven web comprises loops in at least about 10% of the surface area of the nonwoven web. A method for producing a nonwoven web comprising a plurality of loops is also included. The method comprises the steps of providing a nonwoven web; providing means for moving fibers of the nonwoven web into the shape of a loop; and moving fibers of the nonwoven web into the shape of a loop.

    摘要: An expanded polymeric web includes between about 0.1 and about 70 weight percent of a compound comprising nanoparticles. The expanded polymeric web includes between about 30 and about 99.9 weight percent of a generally melt processable polymer. The web also includes between about 0.0 and about 50 weight percent of a compatibilizer. The expanded polymeric web has a 2% machine direction web modulus that is greater than the 2% machine direction web modulus of the expanded polymeric web of the melt processable polymer alone.
