Highly cut-resistant yarn and protective articles made therefrom

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 protective article, comprising a fabric of 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, wherein the protective article is selected from the group consisting of aprons, chaps, sleeves and gloves.  
   
   
       2 . The article of  claim 1 , wherein the fabric is woven.  
   
   
       3 . The article of  claim 1 , wherein the fabric is knit.  
   
   
       4 . A glove in accordance with  claim 1 , wherein the torture chamber life of the glove exceeds the torture chamber life of a glove of equal basis weight consisting of only one fiber of the yarn.  
   
   
       5 . The glove of  claim 4 , having a torture chamber life of at least 90 minutes when the basis weight of the fabric is at least 19 oz/yd 2 .  
   
   
       6 . A glove made from 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), having a torture chamber life of at least 90 minutes when the basis weight of the fabric is at least 19 oz/yd 2 .
