Abstract:
A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.
