Wet-laid nonwoven webs having mechanical reinforcement properties are provided by employing unpulped vegetable fiber bundles as the predominant fiber component. The unpulped fiber bundles have a modulus of elasticity of about 2 - 5 × 106 psi and a chopped fiber length of about 25 mm. The fibers are cordage fibers including sisal, abaca, henequen, kenaf and jute. Composites of the unpulped fiber webs with cellulosic and spunbonded sheets find application as thermoformed vehicle interior trim products.
L'invention porte sur des bandes de non tissés à renfort mécanique obtenues par voie humide utilisant comme constituant fibreux principal des faisceaux de fibres végétales dépulpées. Lesdits faisceaux ont un module d'élasticité d'environ 2 - 5 x 10<6>, et une longueur après tronçonnage d'environ 25 mm. Les fibres sont des fibres de corderie comprenant le sisal, l'abaca, l'henequen, le kénaf et le jute. Les composites de bandes de fibres dépulpées et de feuilles cellulosiques et filées-liées trouvent des applications dans le domaine des garnitures intérieures de véhicules thermoformées.
