The present invention discloses a fabric crepe and in-fabric drying process for producing absorbent sheet, and particularly discloses a method for producing cellulosic absorbent sheet. The method comprises the following steps: a) preparing a cellulosic web from aqueous paper making material, while the web is provided with a plurality of fiber-enriched regions which have higher partical basic weight and have extendable net-shaped structures, the fiber-enriched regions are connected with one another through a plurality of connection areas with lower basic weight, and the net-shaped structures are further characterized by comprising one cohesive fiber base material which can increase the clearance volume in extension; b) drying the web while the extendable net-shaped structures of the fiber are basically sustained; and c) extending the web. The invention also discloses a corresponding absorbent cellulosic web and a crepe absorbent cellulosic web with the net-shaped structures obtained through extension.
