Filed: 1961-11-08
Abstract: 1,009,135. Crinkled filaments. EASTMAN KODAK CO. Nov. 8, 1961 [Nov. 8, 1960], No. 39962/61. Drawings to Specification. Heading B5B. [Also in Division A2] Cigarette filters are produced by extruding a solution of cellulose acetate in acetone with a solids content of 15-30% at a draft ratio of less than 0À15 under a pressure of from 200- 2000 p.s.i.g. at 70-150 C. at an extrusion velocity of 500-2000 M/M. and through orifices of 0À02 to 0À06 mm. into an atmosphere of warm air introduced from above and/or below the point of extrusion so that the extruded filaments float downwardly and are fashioned into highly crinkled and roughened surface form and then converting the filaments into filters. Preferably the filaments are baled as tow and the tow then pulled from the bale, opened and converted to filters. The curing medium may be air, nitrogen or carbon dioxide and the side first struck by the gas shrinks and curls more rapidly, thus placing the other side in tension and producing a crinkly effect. Crinkling may be further aided by passing the filaments as they fall through a compressed air zone such as an air jet. The filaments may be extruded at an angle between vertical and horizontal so that the filaments fall freely through the evaporative medium on to a moving belt, revolving drum, roll or wind up mechanism. A tar removal of 16-55% is achieved.
