Abstract
A protective fabric of high penetration resistance is formed from a plurality of layered, densely woven base fabrics, each formed by tightly weaving multifilament yarns to obtain a warp yarn "density" or "cover" in excess of 100% at the center of the fill yarn, and a fill yarn density or cover preferably also in excess of 75%. The yarns themselves preferably comprise a high modulus, high breaking strength yarn of materials such as Kevlar.RTM., Spectran.RTM., or Vectran.RTM.. The resultant layered fabric offers especially high penetration resistance to weapons such as ice picks and the like. Additional resistance to penetration by sharp knives is provided by interruptedly coating the base fabric with an epoxy in such a manner as to inhibit penetration while providing drapability and breathability.
Claims30
A protective fabric having high penetration resistance, comprising a plurality of layers of tightly woven base fabric having a density in excess of 80 threads/inch in at least of the warp and fill directions and having warp yarn cover of at least 100% at the fill pick.
An article of clothing having high penetration resistance, comprising a plurality of layers of base fabric having a density in excess of 80 threads/inch in at least of the warp and fill directions and having a warp cover at the fill pick in excess of 100% and a fill cover at the warp yarn in excess of 85%.
A protective fabric of high penetration resistance, comprising a plurality of layers of fabric formed from multifilament warp yarns plain woven with fill yarns at such a density as to distort the warp yarns into a keystone structure in which the warp yarns significantly resist movement out of the plane of the fabric in response to force from an otherwise penetrating object.
A protective garment providing substantial resistance to penetration by sharp instruments, including a plurality of layers of plain woven protective base fabric formed of multifilament yarns woven at a density sufficient to distort the warp yarns into a keystone structure at the shed crossing.
A protective fabric comprising a plurality of layers of a tightly woven base fabric, said base fabric constructed from a high modulus tightly woven material having warp yarn cover of at least 100% at the fill pick and having a repeatedly interrupted coating of a plastic material providing flexure points to the base fabric at the areas of interruption.
