Thermal and cut resistant glove

Abstract

A thermal and cut resistant glove includes a main body portion that encloses the palm and back of a user's hand, finger portions and a thumb portion. The glove is 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. The glove exhibits a temperature differential of no more than about 1.3 degrees C. when the front or rear side of the glove is positioned between a refrigerated cold source and a thermocouple after a period of 15 minutes, exhibits a cut resistance of at least about 3500 grams when measured in accordance with ASTM Standard F2992-15, Standard Test Method for Measuring Cut Resistance of Materials Used in Protective Clothing with Tomodynamometer (TDM-100), exhibits an abrasion resistance of at least 2500 cycles when measured tested in accordance with ASTM Standard D3884-07, Standard Guide for Abrasion Resistance of Textile Fabrics, exhibits a time increase of no more than about 25 percent to perform a stated task when measured in accordance with ASTM Standard F2010-10, Standard Test Method for Evaluation of Glove Effects on Wearer Hand Dexterity.

What is claimed is: 
     
         1 . A thermal and cut resistant glove, comprising:
 a main body portion having a front side and a rear side, the main body portion that encloses 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 the glove exhibits a temperature differential of no more than about 1.3 degrees C. when the front or rear side of the glove is positioned between a refrigerated cold source and a thermocouple after a period of 15 minutes,   wherein the glove exhibits a cut resistance of at least about 3500 grams when measured in accordance with ASTM Standard F2992-15, Standard Test Method for Measuring Cut Resistance of Materials Used in Protective Clothing with Tomodynamometer (TDM-100),   wherein the glove exhibits an abrasion resistance of at least 2500 cycles when measured tested in accordance with ASTM Standard D3884-07, Standard Guide for Abrasion Resistance of Textile Fabrics, and   wherein in a dexterity test, the glove exhibits an increase in time to perform a stated task of no more than about 25 percent when measured in accordance with ASTM Standard F2010-10, Standard Test Method for Evaluation of Glove Effects on Wearer Hand Dexterity.   
     
     
         2 . The glove of  claim 1 , wherein the glove exhibits a puncture resistance of at least 77 Newtons when measured in accordance with Standard EN 388:2003. 
     
     
         3 . The glove of  claim 1 , wherein the core is formed from a stainless steel filament. 
     
     
         4 . The glove of  claim 3 , wherein the core includes a UHMWPE filament. 
     
     
         5 . The glove of  claim 1 , wherein the sheath is formed from two wraps of filaments, the two wraps of filaments being in opposite directions. 
     
     
         6 . The glove of  claim 5 , wherein one of the sheath filaments is a polyester fiber. 
     
     
         7 . The glove of  claim 5 , wherein the other of the sheath filaments is a polyester fiber.
