Abstract
878,457. Tobacco smoke filters. BUUREN, VAN, A. J. July 6, 1960, No. 23591/60. Class 130. A filter material for tobacco pipes, cigar or cigarette holders or cigarette tips comprises an ion exchange resin including aromatic groups and having a grain size of not more than 1 mm., and which is in its inactive or neutral condition and has a volume increase of less than 60% upon exposure to water. An anion exchanger, e.g. a metaphenylene diamine and formaldehyde condensate neutralized by nitric acid, and/or a cation exchanger, e.g. a phenolmethylene sulphonic acid condensate neutralized by an alkaline or alkaline earth lye, may be used. The Figure shows a filter rod comprising in a paper wrapper 1 sections 3 of the filter material spaced by normal cellulosic filter rod sections 2 through which the rod is cut to subdivide it into individual cigarette filters.
