Abstract

See full text

A process for producing a filter element suitable for use in smoking articles may include: embedding a bundle of cellulose acetate fibers with an aqueous suspension of polyhydroxyalkanoate (PHA) to obtain a wet bundle of the cellulose acetate fibers covered by the aqueous suspension of the PHA; shaping the wet bundle in a form of a continuous elongated element; heating the continuous elongated element to temperature greater than or equal to 140° C. and less than or equal to 180° C. for time sufficient to melt the PHA and to evaporate water from the continuous elongated element; cooling the heated continuous elongated element to obtain crystallization of the PHA; and cutting the so-obtained continuous elongated element into segments of predetermined length.
