Abstract
A filter for the treatment of gases, particularly tobacco smoke, to reduce their content of suspended solids and organic vapours is made from cellulose ester filaments having a pebbled surface. The filaments are preferably wet-spun cellulose triacetate filaments which may be bonded to each other at their points of contact to form a cigarrette filter plug. The plugs are made by plasticizing and wrapping, suitable plasticizers being triethyl citrate, dimethoxyethyl phthalate, methyl phthalylethyl glycollate, monoacetine, diacetin and triacetin. Suitable filaments may be prepared by the process described in Specification 826,098. A quantitive example is given.
