Abstract
Novel hydraulically entangled spunlaced fabrics and an improved process for making such fabrics composed of at least two types of staple fibers are provided. Elastomeric staple fibers which behave as ordinary staple fibers until heat treated are included in the hydraulically entangled fabric. Upon heat treatment, the elastomeric fibers become elastic and impart improved stretch and resilience properties to the fabric.
