Hydrophobic and oleophobic cut resistant yarn and glove

Abstract

A cut resistant hydrophobic glove includes a main body portion having a front side and a rear side, the main body portion enclosing the palm and back of a user's hand, finger portions and a thumb portion. The main body portion, the finger portions and the thumb portion are each knitted as a single layer of material formed from a yarn that is a composite yarn having a core constructed of one or more core filaments and a sheath constructed of two or more filaments. At least one of the core filaments is a formed from a high performance material having cut resistant properties and at least one of the sheath filaments is formed from a material exhibiting hydrophobic characteristics. A cut resistant hydrophobic sleeve and a yarn for making the glove and sleeve are disclosed.

What is claimed is: 
     
         1 . A cut resistant hydrophobic glove, comprising:
 a main body portion having a front side and a rear side, the main body portion enclosing the palm and back of a user's hand,   finger portions; and   a thumb portion,   wherein the main body portion, the finger portions and the thumb portion are each knitted as a single layer of material formed from a yarn, the yarn being a composite yarn having a core constructed of one or more core filaments and a sheath constructed of two or more filaments,   wherein at least one of the core filaments is a formed from a high performance material having cut resistant properties and wherein at least one of the sheath filaments is formed from a material exhibiting hydrophobic characteristics.   
     
     
         2 . The glove of  claim 1 , wherein the at least one core filament material is one of fiberglass, high molecular weight polyethylene (HMWPE), stainless steel, aramid, liquid-crystal polymer (LCP), aromatic polymer and combinations thereof. 
     
     
         3 . The glove of  claim 1 , wherein the at least one sheath filament material is one of nylon, polyester, cotton, cotton blends and combinations thereof. 
     
     
         4 . The glove of  claim 3 , wherein at least one sheath filaments is formed from a material treated to exhibit hydrophobic characteristics and/or oleophobic characteristics. 
     
     
         5 . The glove of  claim 3 , wherein at least one sheath filaments is formed from a material treated to exhibit hydrophobic characteristics. 
     
     
         6 . The glove of  claim 1  wherein at least one of the sheath filaments is formed from a material exhibiting oleophobic characteristics. 
     
     
         7 . The glove of  claim 3 , wherein at least one sheath filaments is formed from a material treated to exhibit hydrophobic 
     
     
         8 . A sleeve, comprising:
 a body knitted from a yarn, the yarn being a composite yarn having a core constructed of one or more core filaments and a sheath constructed of two or more filaments, wherein at least one of the core filaments is a formed from a high performance material having cut resistant properties and wherein at least one of the sheath filaments is formed from a material exhibiting hydrophobic characteristics.   
     
     
         9 . The sleeve of  claim 8 , wherein the at least one core filament material is one of fiberglass, high molecular weight polyethylene (HMWPE), stainless steel and aramid, liquid-crystal polymer (LCP), aromatic polymer and combinations thereof. 
     
     
         10 . The sleeve of  claim 8 , wherein the at least one sheath filaments is formed from one of nylon, polyester, cotton, cotton blends and combinations and/or blends thereof. 
     
     
         11 . The sleeve of  claim 8 , wherein the at least one of the sheath filaments is formed from a material treated to exhibit hydrophobic characteristics. 
     
     
         12 . The sleeve of  claim 8  wherein at least one of the sheath filaments is formed from a material exhibiting oleophobic characteristics. 
     
     
         13 . A cut resistant hydrophobic yarn, comprising:
 a core constructed of one or more core filaments of a high performance material of fiberglass, high molecular weight polyethylene (HMWPE), stainless steel, aramid, liquid-crystal polymer (LCP), aromatic polymer and combinations thereof having cut resistant properties; and   a sheath constructed of two or more filaments of nylon, polyester, cotton, cotton blends and combinations thereof, at least one of the sheath filaments being treated to exhibit hydrophobic and/or oleophobic characteristics.   
     
     
         14 . The yarn of  claim 13 , wherein the sheath filaments are wrapped together around the core filaments. 
     
     
         15 . The yarn of  claim 13 , wherein one of the sheath filaments is an inner wrap and the other of the sheath filaments is an outer wrap. 
     
     
         16 . The yarn of  claim 15 , wherein the inner wrap is an S-wrap and the outer wrap is a Z-wrap.
