Method of making substrates comprising frothed benefit agents

摘要

The present invention provides a nonwoven substrate comprising a fibrous web defining a surface; and a layer of a benefit agent wherein said benefit agent is selected from an additive composition, an enhancement component and combinations thereof; wherein said benefit agent is frothed and bonded to the fibrous web surface through a creping process. Additionally, the present invention provides for a method of creping a nonwoven substrate and also provides for a nonwoven substrate comprising an adhesive film of an aqueous, frothed, benefit agent.

主权项

1. A method of creping 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) through said applicator, applying to the drying surface an aqueous, frothed, benefit agent wherein said benefit agent comprises an additive composition; d) allowing the frothed, benefit agent to form an adhesive film onto the drying surface, the adhesive film having air bubbles therein; e) directly bonding the nonwoven substrate to the adhesive film positioned on the drying surface; and f) scraping the bonded nonwoven substrate and adhesive film from the drying surface.
