Abstract

A ballistic material is made from spunlace nonwoven fibers mechanically entangled into a woven ballistic fabric. The spunlace nonwoven may comprise low denier fibers providing for a highly dense ballistic product.

Claims (9)

1. A ballistic material, comprising:

a first woven para-aramid ballistic fabric having a fiber denier in a range of 50 d to 5000 d; and

a hydroentangled nonwoven fiber component consisting essentially of ballistic grade para aramid fibers having a denier in a range of about 0.5 d to about 2.5 d and a density of about 10 gsm to about 200 gsm; wherein

the hydroentangled nonwoven component is needlepunched with the woven ballistic fabric to form a consolidated material.

2. The ballistic material according to claim 1 , wherein the hydroentangled nonwoven component consists essentially of fibers having a denier in a range of about 0.5 d to about 2.0 d.

3. The ballistic material according to claim 1 , wherein the ballistic material has a finished areal weight of about 0.1 to about 2.0 pounds per square foot.

4. The ballistic material according to claim 1 , wherein the hydroentangled nonwoven component fibers are coated with a water repellent coating.

5. The ballistic material according to claim 1 , comprising a plurality of woven ballistic fabric layers integrated with the hydroentangled nonwoven component.

6. The ballistic material according to claim 1 , having an areal weight in a range of 0.1 to about 2.0 pounds per square foot and a V50 in a range of about 750 to about 3000 feet per second.
