Abstract

Procédé de façonnage d'une étoffe non tissée, souple et cohérente, à fibres liées par l'action de la chaleur dont au moins 20 % sont constituees de fibres virtuellement adhésives. Le procédé consiste à façonner l'étoffe à une forme souhaitée et à accroître le degré de liaison thermique afin de le porter à une valeur suffisante pour que l'étoffe conserve la forme souhaitée. Domaine d'application : production d'articles divers en étoffe, par exemple de vêtements, d'abat-jours, de housses, de filtres, etc.
