摘要： A process for making absorbent cellulosic paper products such as sheet for towel, tissue and the like, includes compactively dewatering a nascent web followed by wet belt creping the web at an intermediate consistency of anywhere from about 30 to about 60 percent under conditions operative to redistribute the fiber on the belt, which is preferably a fabric. In preferred embodiments, the web is thereafter adhesively applied to a Yankee dryer using a creping adhesive operative to enable high speed transfer of the web of intermediate consistency such as a poly(vinyl alcohol)/polyamide adhesive. An absorbent sheet so prepared from a papermaking furnish exhibits an absorbency of at least about 5 g/g, a CD stretch of at least about 4 percent, and an MD/CD tensile ratio of less than about 1.1, and also exhibits a maximum CD modulus at a CD strain of less than 1 percent and sustains a CD modulus of at least 50 percent of its maximum CD modulus to a CD strain of at least about 4 percent. Products of the invention may also exhibit an MD modulus at break 1.5 to 2 times their initial MD modulus.

摘要： A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a translating transfer surface and is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric. The creping fabric travels at a fabric speed that is slower than the speed of the transfer surface. The nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The creped web is dried to form a dried web, and the dried web is drawn. The drawing step includes drawing the dried web between a first draw roll and a second draw roll.

摘要： A method of making a fabric-creped absorbent cellulosic sheet includes applying a jet of papermaking furnish to a forming wire, the jet having a jet velocity and the forming wire moving at a forming wire velocity. The papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a transfer surface that is moving at a transfer surface speed. The nascent web is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric that is traveling at a fabric-creping speed, the fabric-creping speed being slower than the transfer surface speed, and the fabric-creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric, such that the nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped web. The creped web is dried. The jet/wire velocity delta and the fabric-creping step are controlled such that the dry machine direction to cross-machine direction (MD/CD) tensile ratio of the dried web is about at most 1.5.
