The present invention provides a nonwoven substrate comprising a fibrous web forming a surface and a layer of beneficial auxiliaries, wherein the beneficial auxiliaries are selected from additive compositions, improving ingredients and combinations thereof, wherein the beneficial auxiliaries are foamed and creping process Through the fiber is bonded to the web surface. In addition, the present invention provides a method for creping a nonwoven substrate, the method comprising the steps of: (a) providing the nonwoven substrate, (b) placing the applicator adjacent to the high temperature impermeable dry surface, and (c) Applying an aqueous, foamed, beneficial adjuvant to the dry surface through the applicator, (d) allowing the foamed beneficial adjuvant to form an adhesive film on the dry surface, and (e) on the dry surface. And directly bonding the nonwoven substrate to the adhesive film positioned at, and (f) peeling the bonded nonwoven substrate and the adhesive film from the dried surface. Additionally, the present invention provides a nonwoven substrate comprising an adhesive film of an aqueous foamed beneficial adjuvant, wherein the beneficial adjuvant comprises an additive composition selected from synthetic water-soluble polymers, natural water-soluble polymers and mixtures thereof; An improving component selected from the group consisting of microparticles, thermally expandable microspheres, cut fibers, additive polymer dispersions, perfumes, antibacterial agents, humidifiers, soothers, drugs, and combinations thereof; It is selected from the mixture. |
