Composite yarn for cut resistant fabrics

Abstract

A cut resistant yarn includes a core-spun core. A first layer includes a first filament made of a cut resistant material. The first layer is wrapped around the core-spun core in a first direction, A second layer including a second filament is wrapped around the first layer in a second direction that is opposite of the first direction.

What is claimed is: 
     
         1 . A cut resistant yarn comprising:
 a. a core-spun core;   b. a first layer including a first filament made of a cut resistant material wrapped around the core-spun core in a first direction; and   c. a second layer including a second filament wrapped around the first layer in a second direction that is opposite of the first direction.   
     
     
         2 . The cut resistant yarn of claim wherein the first filament of the first layer is stainless steel. 
     
     
         3 . The cut resistant yarn of  claim 1  wherein the first filament of the first layer is fiberglass. 
     
     
         4 . The cut resistant yarn of  claim 1  wherein the first filament of the first layer has a diameter in the range of 0.0001″ to 0.003″. 
     
     
         5 . The cut resistant yarn of  claim 1  wherein the first layer is wrapped in the Z-direction and the second layer is wrapped in the S-direction. 
     
     
         6 . The cut resistant yarn of  claim 1  wherein the first layer is wrapped in the S-direction and the second layer is wrapped in the Z-direction. 
     
     
         7 . The cut resistant yarn of  claim 1  wherein the second filament of the second layer is a textured filament. 
     
     
         8 . The cut resistant yarn of  claim 1  wherein the second filament of the second layer is selected from the group consisting of Para-aramid, Meta-aramid, UHMWPE, Polyester, Vectran, PPEK, Nylon and Polypropylene. 
     
     
         9 . The cut resistant yarn of  claim 1  wherein the second filament of the second layer has a linear mass density in the range of 40 denier to 650 denier. 
     
     
         10 . The cut resistant yarn of  claim 1  wherein the core-spun core includes extruded fibers or resins that incorporate silver particles. 
     
     
         11 . A method of making a cut resistant yarn comprising the steps of:
 a. spinning a core-spun core;   b. wrapping a first layer including a first filament made of cut resistant material around the core-spun core in a first direction; and   c. wrapping a second layer including a second filament around the first layer in a second direction that is opposite of the first direction.   
     
     
         12 . The method of  claim 11  wherein the first layer is wrapped in the Z-direction and the second layer is wrapped in the S-direction. 
     
     
         13 . The method of  claim 11  wherein the first layer is wrapped in the S-direction and the second layer is wrapped in the Z-direction. 
     
     
         14 . The method of  claim 11  wherein the first filament of the first layer is stainless steel. 
     
     
         15 . The method of  claim 11  wherein the first filament of the first layer is fiberglass. 
     
     
         16 . The method of  claim 11  wherein the first filament of the first layer has a diameter in the range of 0.0001″ to 0.003″. 
     
     
         17 . The method of  claim 11  wherein the second filament of the second layer is selected from the group consisting of Para-aramid, Meta-aramid, UHMWPE, Polyester, Vectran, PPEK, Nylon and Polypropylene. 
     
     
         18 . The method o  claim 11  wherein the second filament of the second layer is a textured filament. 
     
     
         19 . The method of  claim 11  wherein the second filament of the second layer has a linear mass density in the range of 40 denier to 650 denier. 
     
     
         20 . The method of  claim 11  wherein the core-spun core includes extruded fibers or resins that incorporate silver particles.
