Abstract
A wearable container containing a composite which has an alternating pattern containing groupings of woven fabric and groupings of biaxially oriented thermoplastic films. The composite has a thickness of less than about 5 mm. Each grouping of woven fabric contains at least one woven fabric layer, each woven fabric layer containing tape elements having a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. Each grouping of biaxially oriented thermoplastic films contain at least one biaxially oriented thermoplastic film which has a core layer of thermoplastic disposed between covering layers of a thermoplastic able to bond to polypropylene.
Claims16
A protective garment comprising a composite having an upper and lower surface comprising an alternating pattern containing groupings of woven fabric and groupings of biaxially oriented thermoplastic films, wherein the composite has a thickness defined to be the distance between the upper and lower surfaces of less than about 5 mm, wherein the composite comprises;
- wherein each grouping of woven fabric comprises at least one woven fabric layer, each woven fabric layer comprising warp tape elements in a warp direction and weft tape elements in a weft direction which is approximately perpendicular to the warp direction, wherein the tape elements comprise a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer, wherein the warp tape elements and weft tape elements within the woven fabric layer are interwoven and crossover each other at crossover points, wherein the warp elements are bonded to the weft elements within the woven fabric layer at the crossover points;
- wherein each grouping of biaxially oriented thermoplastic films comprises at least one biaxially oriented thermoplastic film, wherein each film comprises a core layer of thermoplastic disposed between covering layers of a thermoplastic able to bond to polypropylene, wherein the layers within each grouping are bonded together;
- wherein woven fabric layers and adjacent biaxially oriented thermoplastic films are bonded together;
- wherein the total thickness of woven fabric layers to biaxially oriented thermoplastic films within the composite is between about 2:1 to 1:50, wherein the groupings of biaxially oriented thermoplastic films have a thickness of between about 0.05 and 5.0 mm, and wherein the tape elements have a cross-sectional shape with a width between about 0.05 mm and 10 mm.
