  • Creping process utilizing low temperature-curing adhesive
    Patent number: 6187140
    Abstract: A method of increasing the wet strength of a creped sheet, which method involves providing a sheet which includes cellulosic fibers, which sheet has a first side and a second side; applying a low temperature-curing latex adhesive binder composition to the first side of the sheet in a fine, spaced-apart pattern occupying from about 20 to about 50 percent of the surface area of the sheet; adhering the first side of the sheet to a creping surface; and creping the sheet from the creping surface. The binder composition is adapted to adhere the sheet to the creping surface and includes a functional group-containing latex, a functional group-reactive crosslinking agent, and a volatile base.
