Abstract
Dans ce procédé de fabrication de filtres pour la fumée de tabac, notamment de filtres de cigarettes, on utilise, soit seules, soit en combinaison avec d'autres fibres d'acétate, de polyoléfine ou de rayonne, des fibres composites formées chacune de deux constituants juxtaposés ou enfermés l'un à l'intérieur de l'autre, dont l'un est du polypropylène ou un copolymère propylénique, tandis que l'autre est un copolymère d'éthylène et d'acétate de vinyle (ce dernier représentant d'environ 0,5 à 18 moles %), un produit de saponification de ce copolymère ou un polymère mixte comprenant en combinaison l'un quelconque des copolymères précédents et du polyéthylène. Le deuxième constituant doit couvrir au moins 60 % de la périphérie extérieure de la section de chaque fibre Ce deuxième constituant fond à une température suffisamment basse pour que, lorsqu'on soumet des faisceaux de fibres à un traitement thermique à une température inférieure au point de fusion du polypropylène les fibres composites se soudent aux points de contact et stabilisent ainsi le faisceau de fibres.
