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.
Claims6
A ballistic material, comprising:
- a first woven co-polymer 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 fiber component is needlepunched with the first woven co-polymer ballistic fabric to form a consolidated material.
