Abstract: A cleansing wipe may be formed from a nonwoven and includes a first ethylene/alpha-olefin interpolymer and a second ethylene/alpha-olefin interpolymer. The cleansing wipe may also have a SaMbSc configuration, wherein the M, meltblown layer, is formed from the first ethylene/alpha-olefin interpolymer and the second ethylene/alpha-olefin interpolymer. The cleansing wipe may be formed a nonwoven comprising bicomponent fibers that incorporate the first ethylene/alpha-olefin interpolymer and the second ethylene/alpha-olefin interpolymer.

Abstract: Provided are bicomponent fibers. The bicomponent fiber comprises a first region and a second region. The first region comprises a first ethylene/alpha-olefin interpolymer, and the second region comprises a second ethylene/alpha-olefin interpolymer. The first ethylene/alpha-olefin interpolymer has a highest peak melting temperature (Tm) less than 130° C. and at least 3.5° C. greater than a highest peak melting temperature of the second ethylene/alpha-olefin interpolymer. The bicomponent fibers can be used for forming nonwovens that in aspect have improved tensile strength, elongation at break, and/or abrasion resistance.

Abstract: Embodiments of a method for producing a multimodal ethylene-based polymer having a first, second, and third ethylene-based component, wherein the multimodal ethylene based polymer results when ethylene monomer, at least one C3-C12 comonomer, solvent, and optionally hydrogen pass through a first solution, and subsequently, a second solution polymerization reactor. The first solution polymerization reactor or the second solution polymerization reactor receives both a first catalyst and a second catalyst, and a third catalyst passes through either the first or second solution polymerization reactors where the first and second catalysts are not already present. Each ethylene-based component is a polymerized reaction product of ethylene monomer and C3-C12 comonomer catalyzed by one of the three catalysts.
