FABRIC CREPING PROCESS FOR PRODUCING ABSORBENT SHEET Russian patent published in 2008 - IPC D21F11/14 B31F1/12 D21H25/00 

FIELD: paper.

SUBSTANCE: compactively dewatering a nascent web having a random distribution of fibre, applying the web to a translating transfer surface moving at the first speed, followed by belt creping the web under pressure at a consistency from about 30 to about 60 percent utilising a creping fabric belt with a patterned creping surface wherein the belt is travelling at a second speed slower than the speed of said transfer surface. Creping conditions are selected such that the web is creped and redistributed on the creping belt to form a web with a reticulum structure having a plurality of interconnected regions of different local basis weights. In preferred embodiments the web is thereafter transferred, being adhesively applied, to a "Yankee" dryer using a creping adhesive to enable high speed transfer of the web. The invention also refers to a web made of cellulose fibre, adsorbent sheet and processes for making one-layer and two-layer tissue.

EFFECT: improving absorbency, voluminosity and relative elongation of the web on retention of high processing rate.
