A bulky, embossed, fibrous web material having a basis weight in the range of 5 to 50 lbs./ream and geometric means tensile strength (TS) (kg/3" width), apparent bulk (AB) (cal. pts./lb. ream), and oil holding capacity (OH) (ml/gm fiber) substantially satisfying, in absolute values, the relationship

A bulky, embossed, fibrous web material having a basis weight in the range of 5 to 50 lbs./ream and geometric means tensile strength (TS) (kg/3" width), apparent bulk (AB) (cal. pts./lb. ream), and oil holding capacity (OH) (ml/gm fiber) substantially satisfying, in absolute values, the relationships (0.27 BW-1) TS>(0.17 BW-1), AB>[0.7-(TS÷20)], and OH 0.063TS2-1.13TS+8.6. The invention includes an apparatus and a method of manufacturing the product comprising wet pressing a fibrous web to about 30% to 50% solids, conveying the web to a transfer position proximate the three-dimensional surface of an embossing fabric moving at a speed less than that of the web at the transfer position, and applying a vacuum to the web through the embossing fabric to transfer and conform the web to the three-dimensional surface of the fabric, the vacuum magnitude being in the range of 1 to 20 inches Hg.

A method of manufacturing a bulky, embossed fibrous sheet material comprising the steps of: (a) forming a wet fibrous web; (b) pressing said web to partially dewater it to between about 30% to about 50% solids; (c) conveying said web to a transfer position proximate the three-dimensional, patterned

A method of manufacturing a bulky, embossed fibrous sheet material comprising the steps of: (a) forming a wet fibrous web; (b) pressing said web to partially dewater it to between about 30% to about 50% solids; (c) conveying said web to a transfer position proximate the three-dimensional, patterned surface of moving fluid-pervious embossing fabric, said web moving at said transfer position in the same direction as and at a speed greater than the fabric; (d) transferring said web at said transfer position to said fabric without substantial mechanical compression of said web; and (e) generally conforming said web to the patterned surface of said fabric essentially solely by applying a vaccum at said transfer position through said fabric to said web; and (f) drying said web.
