WET-LAID NONWOVEN WEB FROM UNPULPED NATURAL FIBERS AND COMPOSITE CONTAINING SAME

摘要

Wet-laid nonwoven webs having mechanical reinforcement properties are provid ed by employing unpulped vegetable fiber bundles as the predominant fiber component. The unpulped fiber bundles have a modulu s of elasticity of about 2 - 5 .times. 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.
