A low-density, soft, bulky and absorbent paper sheet exhibiting a diamond-shaped pattern in its surface after creping, said paper being characterized by having a cross-directional stretch of from about 2 to about 6 percent, as well as improved softness, surface feel and drape, said paper sheet being particularly suitable for use in tissue, toweling and sanitary products. The aforesaid paper sheets are produced by impressing a dot-dash knuckle pattern, wherein the long axis of the dash impressions is aligned parallel to the machine direction of papermaking, using the back side of a monofilament, polymeric fiber, semi-twill fabric of selected coarseness, the knuckle imprint area of which constitutes between about 20 and about 50 percent of the total fabric surface area, as measured in the plane of the knuckles, on an uncompacted paper web at selected fiber consistencies, induced by thermal predrying, prior to final drying and creping.

A soft, bulky and absorbent creped paper sheet characterized by having a uniform basis weight of from about 5 to about 40 pounds per 3,000 square feet, by having imprinted in its surface, to a depth of at least 30 percent of its machine glazed caliper, the knuckle pattern of the back side of a semi-
A soft, bulky and absorbent creped paper sheet characterized by having a uniform basis weight of from about 5 to about 40 pounds per 3,000 square feet, by having imprinted in its surface, to a depth of at least 30 percent of its machine glazed caliper, the knuckle pattern of the back side of a semi-twill imprinting fabric having about 20 to about 60 meshes per inch, by having about 20 to about 50 percent of its surface compressed in said dot-dash knuckle pattern such that the long axis of the dash impressions in said pattern is aligned parallel to the machine direction during the formation of said paper sheet, said paper sheet being further characterized by having a cross-directional stretch of at least about 3.5 percent after creping of said knuckle pattern-imprinted sheet.
