the present invention provides a non-woven substrate comprising a fibrous web defining a surface; and a benefit agent layer, wherein the benefit agent is selected from a composition of additives, an enhancing component and combinations thereof; wherein the beneficial agent is foamed and is bonded to the fibrous weft surface by means of a curling process. the present invention also provides a method of curling a nonwoven substrate comprising the steps of (a) providing a nonwoven substrate; (b) positioning an applicator adjacent to a hot non-permeable drying surface; (c) by means of the applicator, application, on the drying surface, of an aqueous foamed beneficial agent; (d) allowing the foamed benefit agent to form an adhesive film over the drying surface; (e) directly bond the non-woven substrate to the adhesive film positioned on the drying surface; and (f) scraping the bonded non-woven substrate and the adhesive film from the drying surface. additionally, the present invention provides a non-woven substrate comprising an adhesive film of an aqueous foamed benefit agent, wherein the benefit agent is selected from an additive composition selected from a synthetic water-soluble polymer, a polymer soluble in natural water and mixtures thereof; an intensifying component selected from the group consisting of microparticles, thermally expandable microspheres, cut fibers, additional polymer dispersions, fragrances, antibacterials, moisturizers, softeners, medicaments and combinations thereof; and mixtures thereof. |
