Abstract (en)
[origin: EP0479554A2] A method of creping a fibrous web is described which comprises providing to the interface of a fibrous web and a support surface, preferably a drying surface such as provided by a Yankee dryer, a creping adhesive comprising a non-self-crosslinkable material such as a polymer or oligomer having functional groups which are crosslinkable by ionic crosslinking, and a crosslinking agent which preferably comprises metal cations having a valency of at least three, and removing the fibrous web from the support surface by creping. Also provided is a creping adhesive comprising a polymer, oligomer or mixture thereof having functional groups crosslinkable by cations, a component providing metal cations having a valency of at least three, and an aqueous solvent or diluent for the polymer or oligomer. The glass transition temperature and adhesive strength of the adhesive employed in the invention is readily controllable and the adhesive is easily removed from dryer surfaces.
