Cut and abrasion resistant yarn and protective garment made therefrom

Abstract

Provided is a cut and abrasion resistant yarn and safety garment made from such yarn. The yarn includes a cut-resistant core material, covered by a first wrap having at least one strand of a polymeric material wrapped about the core. A second wrap is included and is wrapped about the first wrap in an opposite direction. The second or outer wrap includes at least one strand having a low coefficient of friction. Also provided is a method of making a protective garment from the inventive yarn wherein the protective garment has increased cut and abrasion resistance.

1 . A knittable cut-resistant yarn for use in protective wear comprising: 
 a core having at least one fiber of cut-resistant material; and    at least one wrap wrapped about the core wherein an outermost one of said at least one wrap includes at least one fiber comprising a low coefficient of friction material.    
   
   
       2 . The yarn of  claim 1  wherein said low coefficient of friction material comprises a polytetrafluoroethylene coating.  
   
   
       3 . The yarn of  claim 1  wherein said low coefficient of friction material comprises extruded polytetrafluoroethylene.  
   
   
       4 . The yarn of  claim 1  wherein said cut-resistant fiber of the core is selected from the group consisting of a polyethylene strand, a fiberglass strand, and a stainless steel wire.  
   
   
       5 . The yarn of  claim 4  wherein said stainless steel wire has a diameter of about 0.002 inches.  
   
   
       6 . The yarn of  claim 4  wherein said polyethylene strand has a denier ranging from about 215 to about 1200.  
   
   
       7 . The yarn of  claim 4  wherein said fiberglass strand has a size ranging from about 150 to about 450.  
   
   
       8 . The yarn of  claim 1  wherein said outermost wrap includes a plurality of fibers of a low coefficient of friction material and a plurality of fibers of a second material.  
   
   
       9 . The yarn of  claim 8  wherein said second material is polyester.  
   
   
       10 . The yarn of  claim 9  comprising three fibers of a low coefficient of friction material, each fiber of the low coefficient of friction material having a denier of about 70, and three fibers of a polyester material, each polyester fiber having a denier of about 70.  
   
   
       11 . The yarn of  claim 9  comprising two fibers of a low coefficient of friction material, each fiber of the low coefficient of friction material having a denier of about 70, and one fiber of a polyester material having a denier of about 300.  
   
   
       12 . The yarn of  claim 9  comprising four fibers of a low coefficient of friction material, each fiber of the low coefficient material having a denier of about 70, and one fiber of a polyester material having a denier of about 220.  
   
   
       13 . (canceled)  
   
   
       14 . The yarn of  claim 1  wherein said at least one wrap comprises a polyester material having a denier of about 420.  
   
   
       15 . The yarn of  claim 1  wherein said at least one wrap comprises six fibers of a polyester material, each fiber of the polyester material having a denier of about 70.  
   
   
       16 . The yarn of  claim 1  wherein said at least one wrap comprises two strands of the low coefficient of friction material, each strand having a denier of about 300.  
   
   
       17 . A method of constructing a cut and abrasion resistant glove comprising the steps of: 
 providing a knittable cut and abrasion resistant yarn comprising 
 a core comprising at least one cut-resistant fiber and  
   at least one wrap wrapped about the core, an outermost one of said at least one wrap including at least one fiber comprising a low coefficient of friction material; and    knitting said yarn on a knitting machine in the form of a glove.    
   
   
       18 . The method of  claim 17  wherein said low coefficient of friction material comprises a polytetrafluoroethylene coating.  
   
   
       19 . The method of  claim 17  wherein said low coefficient of friction material comprises extruded polytetrafluoroethylene.  
   
   
       20 . A knittable cut-resistant yarn for use in protective wear comprising a core having at least one fiber of cut-resistant material, and a single wrap wrapped about the core and including at least one fiber comprising a low coefficient of friction material.
