PURPOSE: To obtain the subject fabric having very low wet and dry particle counts and high absorbency and useful for a cleanroom wiper application by treating a mixed web of an acrylic fibrous and a polyester fiber with a low impact water stream jet energy. CONSTITUTION: Firstly, a lightweight web 10 comprising 10-90 wt.% acrylic fiber and 10-90 wt.% polyester fiber is supported on a mesh screen 12. Then the web 10 supported on the mesh screen 12 is passed underneath an energy water jet providing a total impact energy of no greater than 30 Hp-hr-lb.sub.f /lb.sub.m to entangle the acrylic fiber with the polyester fiber and produce a spunlaced fabric. Preferably, the web is then passed through a vacuum dewaterer 19 to remove particles that may be suspended in the water after jetting. |
