Abstract
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 is employed for hydroentangling a precursor web to form a fabric. High-speed production of relatively low basis weight fabrics can be achieved, with the fabrics exhibiting desired softness, uniformity, and strength characteristics.
