Papermaking fabrics having machine and cross-machine direction elements and paper products made therewith
The present invention discloses a papermaking fabric having a both machine direction (MD) and cross-machine direction (CD) oriented protuberances for molding and structuring a nascent paper web, particularly tissue paper webs. The MD oriented protuberances are spaced apart from one another in the fabric cross-machine direction and may be continuous and parallel to one another. The CD oriented protuberances are preferably discrete and comprise less than 15 percent of the web contacting surface of the fabric. In certain instances the MD oriented protuberances are formed from interwoven filaments and the CD oriented protuberances are nonwoven and may be applied to the woven fabric substrate by printing.

Deeply Embossed Highly Permeable Cigarette Paper
A smoking article wrapper includes a non-perforated air permeable base paper having a naturally high porosity of 40-80 cm.sup.3/min air passing through a sample of 1 cm.sup.2 of this base paper at an applied pressure difference of 1 kPa, wherein the smoking article wrapper has at least one embossed surface area and at least one non-embossed surface area. The air permeability of the smoking article wrapper is such that it provides a mean volumetric flow rate of ≥40 cm.sup.3/min air passing through a sample of 1 cm.sup.2 of this smoking article wrapper at an applied pressure difference of 1 kPa. The embossed area includes an embossing having a depth of ≥16 μm. A smoking article including the smoking article wrapper and respective methods to produce such a smoking article wrapper and a smoking article are also provided.
