Abstract

Hydrophilic open-celled resilient latex foams characterized by a droplet acquisition rate of less than 5 seconds and a Free Swell Capacity of at least 5 g/g are prepared by treating open-celled resilient latex foams with at least one hydrophilicizing agent and are used in hygiene articles to acquire, distribute and inmmobilize body fluids.
