| 摘要 |
A net formed integrally of blended incompatible polymers with parallel smooth longitudinal ribs interconnected by a plurality of split strands non-uniformly interspersed with a plurality of differently sized voids, by stretching a film with a generally longitudinal set of parallel primary grooves and a transverse or angled set, on the other surface, of parallel secondary grooves. The net thus formed resembles a woven textile material, can provide good transmission of clear or nonhomogenous liquid and can be used for example in babies diapers, sanitary towels or light structures as a cover layer. |
