Abstract

An insert for a protective garment, the insert having a fabric having at least 45 percent by weight of expanded polytetrafluoroethylene fibers, the fabric having a 2-Grain V-50 Fragmentation Resistance of at least 700 feet per second and a FAST-2 Bending Rigidity of less than 40 microNewtonmeters.

Claims (17)

1. An article comprising an insert for a protective garment, said insert comprising a fabric having at least 45 percent by weight of expanded polytetrafluoroethylene fibers, said fabric having a 2-Grain V-50 Fragmentation Resistance of at least 700 feet per second and a FAST-2 Bending Rigidity of less than 40 microNewtonmeters; and said fabric having a weight of less than 160 grams per square meter.

2. An article as defined in claim 1 wherein said fabric has at least 75 percent by weight of polytetrafluoroethylene fibers.

3. An article as defined in claim 1 wherein said fabric comprises 100 percent by weight of polytetrafluoroethylene fibers.

4. An article as defined in claim 1 wherein said fabric has a 2-Grain V-50 Fragmentation Resistance of at least 800 feet per second.

5. An article as defined in claim 1 wherein said fabric has a Vertical Wicking after 10 minutes of less than 150 mm.

6. An article as defined in claim 1 wherein said fabric has a Vertical Wicking after 10 minutes of zero mm.

7. An article as defined in claim 1 wherein said FAST-2 Bending Rigidity is less than 30 microNewtonmeters.

8. An article as defined in claim 1 wherein said FAST-2 Bending Rigidity is less than 20 microNewtonmeters.

9. An article as defined in claim 1 wherein said FAST-2 Bending Rigidity is about 10 microNewtonmeters.

10. An article comprising an insert for a protective garment, said insert comprising a fabric having at least 45 percent by weight of expanded polytetrafluoroethylene filaments having a tenacity of less than 10 grams per dtex, said fabric having a 2-Grain V-50 Fragmentation Resistance of at least 700 feet per second and said fabric having a weight of less than 160 grams per square meter.

11. An article as defined in claim 10 wherein said fabric has at least 75 percent by weight of polytetrafluoroethylene filaments.

12. An article as defined in claim 10 wherein said fabric comprises 100 percent by weight of polytetrafluoroethylene filaments.

13. An article as defined in claim 10 wherein said fabric has a 2-Grain V-50 Fragmentation Resistance of at least 800 feet per second.

14. An article as defined in claim 10 wherein said fabric has a Vertical Wicking after 10 minutes of less than 150 mm.

15. An article as defined in claim 10 wherein said fabric has a Vertical Wicking after 10 minutes of zero mm.

16. An article as defined in claim 10 wherein said fabric has a weight of less than 140 grams per square meter.

17. An article as defined in claim 10 wherein said fabric has a weight of less than 120 grams per square meter.
