Abstract
Improved liquid-barrier properties are provided to spunlaced fabrics of woodpulp and synthetic organic fibers by employing closely spaced jets in a hydraulic entanglement treatment of the fibers. Additional improvement in barrier properties is provided by a finishing step which employs multiple passes under low pressure, closely spaced jets.
