Fabric crepe and in fabric drying process for producing absorbent sheet |
摘要 |
A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web having an apparently random distribution of papermaking fiber. The dewatered web is applied to a translating transfer surface. The web is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, under pressure, in a fabric creping nip defined between the transfer surface and the creping fabric. The fabric is traveling a fabric speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping fabric to form a web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The web is dried and the web is drawn. The step of drawing the web preferentially attenuates the fiber-enriched regions of the web. |
