ABSTRACT:
A method for creping fibrous webs comprises: (1) applying to a drying surface for the fibrous web a polyamine/epihalohydrin resin creping adhesive; (2) applying a creping release agent that is a plasticizer for the polyamine/epihalohydrin resin and has a swelling ratio of at least 0.10 and a solubility parameter of greater than 20 MPa.sup.1/2 ; (3) pressing the fibrous web against the drying surface to adhere the web to the drying surface, and (4) dislodging the web from the drying surface with a creping device to crepe the fibrous web.
