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: Embodiments of the present disclosure am directed to multilayer thermoset composites which comprise a first fabric reinforcement layer, a nonwoven fabric, and a second fabric reinforcement layer. The nonwoven fabric may be positioned between the first fabric reinforcement layer and the second fabric reinforcement layer. A thermoset resin may at least partially permeate the first fabric reinforcement layer, the nonwoven fabric, and the second fabric reinforcement layer. The thermoset resin may be an epoxy, unsaturated polyester, or polyurethane. The first and second fabric reinforcement layer may each comprise one or more of glass fiber, carbon fiber, polyaramid fiber, polyethylene fiber, or basalt fiber. The nonwoven fabric may be formed from bicomponent fibers having a sheath/core configuration. The sheath may be formed from ethylene-carboxylic acid copolymers, or ionomers of ethylene-carboxylic acid copolymers. Further embodiments include methods of making the multilayer thermoset composite.
