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.

Claims (9)

1. A process for making spunlaced acrylic/polyester fabrics comprising the steps o~
(a) supporting a lightweight web of fibers on a mesh screen wherein the fibers comprise a blend of 10-90 wt.% acrylic fibers and 10-90 wt.% polyester fibers;
and (b) passing the supported web underneath low energy water jets operating at a total impact energy no greater than 30 Hp-hr-lb f/lb m to entangle the acrylic and polyester fibers and form a spunlaced fabric.
2. The process of claim 1 further comprising the step of vacuum dewatering the spunlaced fabrics to remove water and suspended particles.
3. The process of claim 1 wherein the web is passed underneath the water jets at a speed of between 20 to 200 yds/min.
4. A process for making spunlaced acrylic/polyester fabrics comprising the steps of:
(a) supporting a lightweight web of fibers on a mesh screen wherein the fibers comprise a blend of 30-90 wt.% acrylic fibers and 10-70 wt.% polyester fibers;
(b) passing the supported web underneath low energy water jets operating at a total impact energy between 5 and 28 Hp-hr-lb f/lb m to entangle the acrylic and polyester fibers; and (c) vacuum dewatering the spunlaced fabric to remove water and suspended particles.
5. The process of claim 4 wherein the web is passed underneath the water jets at a speed of between 20 to 200 yds/min.
6. A spunlaced acrylic/polyester fabric having a dryparticle count no greater than 5000, a wet particle count no greater than 9500, an absorbency rate of at least 0.1 gm/gm/sec and an absorbency capacity of at least 600%.
7. The spunlaced acrylic/polyester fabric of claim 6 wherein the dry particle count is no greater than 1000, the wet particle count is no greater than 8000, the absorbency rate is at least 0.25 gm/gm/sec and the absorbency capacity is at least 700%.
8. A spunlaced acrylic/polyester fabric produced by the process of any one of claims 1-5.
9. The spunlaced fabric of claim 6 wherein the fabric comprises a cleanroom wiper or coverstock for sanitary napkins and diapers.
