发明名称 Filter cigarette having filter containing absorptive synthetic graft polymer fibers produced from irradiated polyethylene reacted with vapor phase styrene or absorptive synthetic magnetic fibers
摘要 A filter cigarette is provided which has a cigarette section formed by wrapping shredded tobacco in a cigarette paper sheet and a filter section having a filter chip integrally joined to the cigarette section. The filter chip is formed by combining in a bundle at least one absorptive synthetic fiber selected from the group consisting of (1) graft polymer fibers produced from irradiated polypropylene reacted with vapor phase styrene and containing adsorptive functional groups, (2) activated carbon fibers, (3) charged electret fibers, and (4) magnetic plastic fibers and then chopping the combined fiber bundle to a predetermined length. Since the filter section does not contain adsorptive grains or particles (i.e., activated charcoal grains or particles), the integrated cigarette manufacturing plant for such filter cigarettes does not required a process or equipment for preventing the scattering of the adsorptive grains or the collection of such grains when they do escape.
