ABSTRACT:
A process is disclosed for making spunlaced acrylic/polyester fabrics comprising applying low impact water jet energy to a fabric web and vacuum dewatering the resulting spunlaced fabric. The spunlaced fabrics exhibit very low wet and dry particle counts and high absorbency thereby making them particularly useful in cleanroom wiper applications and as coverstock for sanitary napkins, diapers and the like.
