Abstract
Wiping products are disclosed comprising a sheet and an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the sheet by being combined with the fibers that are used to form the sheet. Alternatively, the additive composition may be topically applied to the sheet after the sheet has been formed. For instance, in one embodiment, the additive composition may be applied to the sheet as a creping adhesive during a creping operation. The additive composition may improve the strength of the sheet and/or improve the perceived softness of the sheet.
