Method Of Making A Belt-Creped Absorbent Cellulosic Sheet |
摘要 |
A method of making a belt-creped absorbent cellulosic sheet includes compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber, applying the nascent web having the apparently random fiber distribution to a translating transfer surface that is moving at a transfer surface speed, belt-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping belt, the belt-creping step occurring under pressure of at least 20 pounds per linear inch in a belt creping nip defined between the transfer surface and the creping belt. The belt is traveling at a belt speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping belt. |
