Abstract

A fabric comprising a cut-resistant polymeric coating including by weight 1 to 10 percent para-aramid particles, the particles having an average particle size of 20 to 500 microns.

Claims (10)

1. A cut resistant article comprising a knit fabric comprising a polymeric coating on the surface of the fabric, the polymeric coating consisting of elastomeric material and 1 to 10 percent para-aramid particles by weight, the particles having an average particle size of 120 to 500 microns,

wherein the article is a glove, apron, or sleeve.

2. The cut resistant article of claim 1 wherein the para-aramid particles are poly(praraphenylene terephthalamide) particles.

3. The cut resistant article of claim 1 wherein the fabric comprises yarns of para-aramid fibers, meta-aramid fibers, polyamide fibers, polypropylene fibers, polyethylene fibers, polyester fibers, or any mixture thereof.

4. The cut resistant article of claim 3 wherein the para-aramid fibers are poly(praraphenylene terephthalamide) fibers.

5. The cut resistant article of claim 1 wherein the elastomeric material is polyurethane elastomer, nitrile rubber, vinyl rubber, polyisoprene, neoprene, chloroprene, polychloroprene, acrylonitrile butadine, carboxylated acrylonitrile butadiene, styrene-butadiene, ethylene vinyl acetate, or some combination of these.

6. The cut resistant article of claim 5 wherein the elastomeric material is a polyurethane.

7. The cut resistant article of claim 5 wherein the elastomeric material is a nitrile rubber.

8. The cut resistant article of claim 1 , wherein the fabric has a basis weight of 100 to 1000 grams per square meter (3 to 30 ounces per square yard).

9. The cut resistant article of claim 8 , wherein the fabric has a basis weight of 170 to 850 grams per square meter (5 to 25 ounces per square yard).
