  • Highly Resilient, Dimensionally Recoverable Nonwoven Material
    Publication number: 20080311343
    Abstract: A microcreped wet laid nonwoven with recoverable stretch suitable for apparel applications such as waistbands and interlinings. The microcreping and heat setting improves dimensional stability after washing and drying cycles, minimizes shrinkage and substantially eliminates the surface wrinkling phenomenon, known in the industry as “alligatoring”, associated with wet laid and other apparel nonwovens.

  • Wet-laid nonwoven web from unpulped natural fibers and composite containing same
    Patent number: 6762138
    Abstract: 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.
