Abstract
Official abstract text for this publication.
Provided among other things is a cut-resistant article comprising: a cut-resistant synthetic fabric; and adherent to the fabric a layer of polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 16, wherein the article has a cut resistance by ISO 13997:1999 of 2 or higher.
First claim
Opening claim text (preview).
What is claimed is: 1. A cut-resistant article comprising: a fabric; and adherent to the fabric a layer of polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and consisting of fibers of L/D ratio between about 8 and about 14, wherein the article has a cut resistance by EN388 of 3 or higher. 2. The cut-resistant article of claim 1 , wherein the mineral fibers have average D mass weighted from about 5 to about 23 micron. 3. The cut-resistant article of claim 2 , wherein the mineral fibers have average L mass weighted from about 100 to about 210 micron. 4. The cut-resistant article of claim 2 , wherein the mineral fibers have average L mass weighted from about 100 to about 170 micron. 5. The cut-resistant article of claim 2 , wherein the mineral fibers have hardness of about 5 Mohs or higher. 6. The cut-resistant article of claim 1 , wherein the mineral fibers have hardness of about 5 Mohs or higher. 7. The cut-resistant article of claim 1 , wherein the fabric is a cut-resistant synthetic fabric. 8. The cut-resistant article of claim 1 , wherein the mineral fibers consist of fibers of L/D ratio of about 8 to less than 10. 9. The cut-resistant article of claim 8 , wherein the fabric comprises 80% or more polyamide cut resistant yarn. 10. The cut-resistant article of claim 8 , wherein the fabric comprises 85% or more polyamide cut resistant yarn. 11. The cut-resistant article of claim 8 , wherein the fabric comprises 70% or more polyamide cut resistant yarn. 12. The cut-resistant article of claim 8 , wherein the mineral fibers have average D mass weighted from about 5 to about 23 micron. 13. The cut-resistant article of claim 12 , wherein the mineral fibers have average L mass weighted from about 100 to about 210 micron. 14. The cut-resistant article of claim 12 , wherein the mineral fibers have average L mass weighted from about 100 to about 170 micron. 15. The cut-resistant article of claim 12 , wherein the mineral fibers have hardness of about 5 Mohs or higher. 16. The cut-resistant article of claim 8 , wherein the mineral fibers have hardness of about 5 Mohs or higher. 17. The cut-resistant article of claim 8 , wherein the polymer is a substantially polyurethane polymer, and wherein the article has a cut resistance greater than that of a comparable article that substitutes the fiber with mineral fiber having L of about 125 and D of about 7. 18. The cut-resistant article of claim 8 , wherein the article has a cut resistance greater than that of a comparable article that substitutes the fiber with mineral fiber having L of about 125 and D of about 7. 19. The cut-resistant article of claim 8 , wherein the polymer is a substantially polyurethane polymer, and wherein the article has a cut resistance greater than that of a comparable article that substitutes the fiber with mineral fiber having L of about 125 and D of about 7. 20. The cut-resistant article of claim 1 , the article has a cut resistance greater than that of a comparable article that substitutes the fiber with mineral fiber having L of about 125 and D of about 7.
