Abstract
A woven fabric useful in protective apparel made from yarn components comprising a body fabric yarn component, a synthetic ripstop yarn component having at least 20% greater tensile strength than the body fabric yarn component, and a cut resistant yarn component comprising a yarn having a synthetic staple-fiber sheath and inorganic core, the body fabric yarn component, the ripstop yarn component, and cut-resistant yarn components all being comprised of at least one yarn and each yarn component distinguished from the adjacent yarn component by interweaving orthogonal yarn components.
Claims17
A woven fabric useful in protective apparel made from yarn components comprising:
- a) a body fabric yarn component,
- b) a synthetic ripstop yarn component having at least 20% greater tensile strength than the body fabric yarn component, and
- c) a cut resistant yarn component comprising a yarn having a synthetic staple-fiber sheath and inorganic core,
- the body fabric yarn component, the ripstop yarn component, and cut-resistant yarn components all being comprised of at least one yarn and each yarn component distinguished from the adjacent yarn component by interweaving orthogonal yarn components.
A woven fabric useful in protective apparel made from orthogonal warp and fill yarn components comprising:
- a) a body fabric yarn component,
- b) a synthetic ripstop yarn component having at least 20% greater tensile strength than the body fabric yarn component, and
- c) a cut resistant yarn component comprising a yarn having a synthetic fiber sheath and inorganic core,
- the body fabric yarn component, the ripstop yarn component, and cut-resistant yarn components all being comprised of individual or plied warp and fill yarns in the fabric, and
- wherein every fifth to ninth orthogonal warp and fill yarn component is a ripstop yarn component.
A woven fabric useful in protective apparel made from orthogonal yarn components comprising:
- a) a body fabric yarn component,
- b) a synthetic ripstop yarn component having at least 20% greater tensile strength than the body fabric yarn component, and
- c) a cut resistant yarn component comprising a yarn having a synthetic staple-fiber sheath and inorganic core,
- the body fabric yarn component, the ripstop yarn component, and cut-resistant yarn components all being comprised of at least one yarn and each yarn component distinguished from the adjacent yarn component by interweaving orthogonal yarn components, said ripstop yarn components being orthogonal to said cut resistant yarn components.
A process for making a woven fabric useful in protective apparel made from warp and fill yarn components comprising:
- a) weaving a fabric from a body fabric yarn component and a cut-resistant yarn component, the cut resistant yarn component comprising a yarn having a synthetic staple-fiber sheath and inorganic core, and
- b) inserting into the weave at every fifth to ninth warp and fill component a synthetic ripstop yarn component having at least 20% greater tensile strength than the body fabric yarn component.
A process for making a woven fabric useful in protective apparel made from orthogonal yarn components comprising:
- a) weaving a fabric from a body fabric yarn component,
- b) inserting into the weave at every fifth to ninth yarn component a synthetic ripstop yarn component to create a parallel array of ripstop yarn components, each component having at least 20% greater tensile strength than the body fabric yarn component, and
- c) inserting into the weave, orthogonal to the array of parallel ripstop yarn components, a parallel array of cut-resistant yarn components, each cut resistant yarn components comprising a yarn having a synthetic staple-fiber sheath and inorganic core.
