摘要： Disclosed is a filter element (21) for a cigarette, and a cigarette incorporating such a filter element, comprising an outer wall provided by a plug wrap (4) surrounding an axially extending porous barrier tube (2) of micro-fine fibres. The space therebetween is filled with a porous filtering material (3). A porous support in the form of a rod of filtering material (5) is provided with an adhesive layer in the form of an adhesive tube (1). The core rod, comprising the barrier tube (2), adhesive tube (1), and porous support (5) is crimped to form a crimp (6) impervious for gas flow. The adhesive layer may conveniently be provided by an adhesive material, for example nitrile rubber, vinyl acetate-acrylic acid, vinyl acetate-ethylene, polyacrylate (carboxylic) polyamides, polyimides, polyhydroxy ether, polyester plus isocyanate, or another suitable adhesive. The material WUNDAWEB is particularly suitable.
