FABRIC CREPE PROCESS FOR MAKING ABSORBENT SHEET

摘要

A method of making a belt-creped absorbent cellulosic sheet is described. The method comprises compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber. The dewatered web which has the apparently random fiber distribution is applied to a translating transfer surface moving at a first speed. The web is belt-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping belt. The creping step occurring under pressure in a belt creping nip defined between the transfer surface wherein the creping belt is urged into contact with the transfer surface over a nip length by way of a deformable creping roll wherein the belt is traveling at a second speed slower than the speed of the transfer surface. The belt pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and redistributed on the creping belt. The web is then dried.
