Highly cut-resistant yarn and protective articles made there from

Abstract

A cut-resistant composite yarn, comprising a high strength organic fiber having a tenacity greater than 15 grams per denier and a hard-particle-filled thermoplastic fiber useful in making fabrics from which protective articles, such as gloves are made.

1 . A cut resistant fabric, comprising cut-resistant composite yarn, comprising a high strength organic fiber having a tenacity greater than 15 grams per denier and a hard-particle-filled thermoplastic fiber.  
   
   
       2 . A cut resistant fabric, comprising a cut-resistant composite yarn, wherein the yarn comprises poly(paraphenylene terephthalamide) and poly(ethylene terephthalate) filled with about 0.1 to 10 weight percent of hard particles, based on the total weight of hard particles plus poly(ethylene terephthalate).  
   
   
       3 . The cut resistant fabric of  claim 1 , wherein the fabric is woven.  
   
   
       4 . The cut resistant fabric of  claim 1 , wherein the fabric is knit.  
   
   
       5 . The fabric of  claim 1 , wherein the fabric has a cut protection performance value of at least 500 grams at a basis weight of at least 6 ounces per square yard when tested in accordance with ASTM F1790-97.  
   
   
       6 . The fabric of  claim 1 , wherein the fabric has a cut protection performance value of at least 1000 grams at a basis weight of at least 12 ounces per square yard when tested in accordance with ASTM F1790-97.  
   
   
       7 . The fabric of  claim 1 , wherein the fabric has a cut protection performance value of at least 1500 grams at a basis weight of at least 19 ounces per square yard when tested in accordance with ASTM F1790-97.  
   
   
       8 . The fabric of  claim 1 , wherein the cut protection performance when tested in accordance with ASTM F1790-97 is greater than the cut protection performance of a fabric of equal basis weight and construction consisting of any single yarn of which the composite yarn of  claim 1  comprises.
