摘要： A low-compaction method of making an absorbent cellulosic web includes: forming a nascent web from a papermaking furnish; dewatering the nascent web to a consistency of from about 10 to about 30 percent on a foraminous forming support traveling at a first speed; rush-transferring the web at a consistency of from 10 to about 30 percent to an open texture fabric traveling at a second speed slower than the first speed of the forming support; further dewatering the web on the impression fabric to a consistency of from about 30 to about 60 percent by way of (i) combining the open texture fabric bearing said web with a fluid distribution membrane and an anti-rewet felt as the three pass through a nip into a pressure chamber defined in part by a plurality of nip rolls, the fluid distribution membrane bearing against the side of the open texture fabric away from the web, with the anti-rewet felt bearing against the web, and (ii) applying a pneumatic pressure gradient from the distributor membrane through the web thereby dewatering the web; and drying the web. Preferably the process includes the steps of selecting the papermaking furnish and controlling the process such that the dried web has a void volume fraction of at least 0.7, a hydraulic diameter in the range of from about 3 to about 20 microns and a Wet Springback Ratio of at least about 0.65. Optionally provided is a high solids fabric crepe in a pressure nip.

Preferably, the fiber web is once more pressed onto an imprinting fabric by means of a second pressure field in order to fix strength without destroying the three dimensional surface structure. The fiber web is preferably guided between the first and the second pressure field through said at least one third pressure field. Preferably, the same imprinting fabric is used in said first pressure field and said second pressure field. Moreover, the dry content is achieved by a favorably priced apparatus instead of by TAD drying apparatus.

摘要： A wet paper web or other wet porous web exiting a web former is supported on a vented press roll (40) and sequentially subjected to a relatively high pressure mechanical nip pressing force (42) and a relatively low pressure water displacement-pressing force. The combination of the two diverse pressing forces (42, 43, 44) applied in sequence to the web is very effective in efficient and economical de-watering of the web and at the same time provides a de-watered web having high bulk, high solids content and high mechanical strength. The low pressure fluid displacement pressing force is applied immediately contiguous to the high pressure mechanical nip pressing force and may be applied upstream (43) or downstream (44) or both upstream and downstream of the mechanical nip pressing force (42).
