Abstract
According to some aspects, a method of manufacturing a coated multi-threat fabric, including providing a first fabric layer having a first surface, the first fabric layer having a plurality of high performance fibers, applying a first polymeric material onto the first surface of the first fabric layer, the polymeric material having a melt flow index of between about 0.7 to 1400 g/10 min, a Shore D hardness of between about 36 and 75, and ultimate tensile strength of between about 5 and 75 MPa, spreading the first polymeric material onto the first surface of the first fabric layer so as to form a raw coated fabric having a first coating layer, and heating the raw coated fabric to bond the first coating layer to the first fabric layer, wherein the first polymeric material is selected such that the coated multi-threat fabric is flexible enough to be stored on a roll of a predetermined size. In some aspects, a coated multi-threat fabric includes at least one layer of fabric, each layer having a plurality of high performance fibers, and at least one coating of polymeric material bonded to the at least one layer of fabric, the polymeric material comprising an ethylene acrylic acid copoly…
