HYDROENTANGLED, LOW BASIS WEIGHT NONWOVEN FABRIC AND PROCESSFOR MAKING SAME

摘要

A process is disclosed for hydroentangling polymeric filament webs for production of low basis weight nonwoven fabrics. A hydroentangling device having a foraminous forming surface (12) i s employed for hydroentangling a precursor web (P) to form a fabric. High-speed production of relatively low basis weight fabri cs can be achieved, with the fabrics exhibiting desired softness, uniformity, and strength characteristics.
