    摘要： An oil resistant article is described that does not contain any fluorocarbon compounds. The oil resistant article includes a basesheet formed from pulp fibers. The basesheet is coated on at least one surface with an oil resistant coating. The basesheet is formed without having to use any highly refined fibers. Various chemical treatments are incorporated into the basesheet and the oil resistant coating is formed from particularly selected polymers that produces an oil resistant article having a relatively high permeability and excellent oil resistant properties.

    摘要： A smoking article wrapper has discrete areas of reduced permeability for improving ignition proclivity characteristics of a smoking article. The reduced permeability areas define a gradually decreasing permeability profile in a burning direction of the smoking article such that permeability reduction in the reduced permeability areas increases from a minimum reduction to a maximum permeability reduction in the burning direction of the smoking article.

    摘要： Disclosed is a filter for tobacco smoke composed of at least one layer of a wet-formed absorbent fibrous nonwoven composite structure containing: 1) from about 30 to about 65 percent, by weight, of pulp fibers forming a matrix having a first exterior surface and a second exterior surface; and 2) about 35 to about 70 percent, by weight, of activated carbon integrated into the matrix of pulp fibers such that the concentration of activated carbon adjacent the first exterior surface is at least about 60 percent, as determined by optical image analysis, and the concentration of activated carbon adjacent the second exterior surface is less than about 40 percent, as determined by optical image analysis, so that the filter is adapted to selectively reduce the C.sub.3 -C.sub.4 carbonyl component of conventional tobacco smoke at least about 25 percent more than a conventional cellulose acetate filter for an identical tobacco smoke. Also disclosed is a method of making the filter.
