ABSTRACT:
Using a slurry containing a particulate or fibrous cellulose ester and a wood pulp with a Canadian standard freeness of 100 to 800 ml in a ratio of 10/90 to 90/10 (weight %), a tobacco filter material in the form of a sheet having a nonwoven web structure is produced. The slurry may contain a microfibrillated cellulose in a proportion of 0.1 to 10 weight % on a nonvolatile matter basis. The cellulose ester may be a cellulose acetate with a combined acetic acid in the range of 30 to 62%. This tobacco filter material in a sheet form can be applied to a tobacco filter having a high dry strength and, yet, a high degree of wet disintegratability without adversely affecting the smoking quality of tobacco. Thus, the potential environmental pollution is mitigated by the tobacco filter.
