Abstract
A process is provided for manufacturing a smokeable material including a basic material consisting of calcium alginate in fibrous form into which filler material is incorporated. The calcium alginate fibers are formed from the admixture of two solutions, the filler material being suspended in at least one of the solutions in such quantity and the solutions being so mixed that the filler is incorporated integrally in the fibres as they are formed so as to constitute more than 10% of the fibres by weight.
