Abstract
A smokeable material comprises a base material, consisting of calcium-alginate fibers, and additional material which renders the smokeable material suitable for use in place of smoking tobacco. The additional material may consist of tobacco alone, but alternative or other additional materials include cellulosic fibers (wood pulp), a coloring agent, a nicotine donor, flavor-modifiers, and a burning sustainer. It is also disclosed that calcium-alginate fibers will (unexpectedly) papermake in the traditional manner used for non-synthetic fibers, and the above additional material may, or may not, be incorporated during such papermaking. Any incorporated tobacco is preferably 55% or less, by weight, added by blending or otherwise. Where there is no tobacco, there may be preferably (by weight) at least 80% of calcium-alginate fibers, and 10% each of the cellulosic fibers, and total other constituents.
