Gloves

Abstract

A glove is disclosed which includes a porous coating layer provided on the surface of a glove made of a fiber, wherein a plurality of pores having an area of 0.785 to 78.5 μm 2 are present, and an average of the smallest thickness of each resin layer existing between the pores for the respective pores is 0.9 to 178 μm in an electron-microscopic field at the time when a finger pad central portion, 40 mm away from a finger tip toward a finger pad, of a finger portion in the porous coating layer is cut off and a cross-section of 253 μm in length directed from the finger tip toward the finger pad and 2.5 to 10 μm in depth from a surface of the porous coating layer is observed at a magnification of 500 times with an electron microscope. The glove of the present invention is superior in abrasion resistance and peel strength, has excellent resistance to peeling/migration to pressure-sensitive adhesive tapes, and is superior in moisture permeability and flexibility.

1 . A glove including a porous coating layer provided on the surface of a glove made of a fiber, wherein
 a plurality of pores having an area of 0.785 to 78.5 μm 2  are present, and   an average of the smallest thickness of each resin layer existing between the pores for the respective pores is 0.9 to 178 μm   in an electron-microscopic field at the time when a finger pad central portion, 40 mm away from a finger tip toward a finger pad, of a finger portion in the porous coating layer is cut off and a cross-section of 253 μm in length directed from the finger tip toward the finger pad and 2.5 to 10 μm in depth from a surface of the porous coating layer is observed at a magnification of 500 times with an electron microscope.   
     
     
         2 . The glove according to  claim 1 , wherein a void ratio of the total area of pores having an area of not less than 0.785 μm 2  to an area of the electron-microscopic field is 0.3 to 75%. 
     
     
         3 . The glove according to  claim 1 , wherein a number of pores having an area of 0.785 to 78.5 μm 2  in the electron-microscopic field is 2 to 35. 
     
     
         4 . The glove according to  claim 1 , wherein the thickness of the porous coating layer is 7.5 to 150 μm. 
     
     
         5 . The glove according to  claim 1 , wherein the porous coating layer comprises a polyurethane resin. 
     
     
         6 . The glove according to  claim 5 , wherein a glove made of a fiber put on a hand mold is dipped into a polyurethane resin solution, and the hand mold is pulled up to remove the excessive resin solution, and the hand mold is dipped into water or warm water containing an organic solvent with a solubility parameter of 6.0 to 10.5 in an amount of 0.01 to 20% by weight to cause the polyurethane resin to gel in a porous state. 
     
     
         7 . The glove according to  claim 5 , wherein a glove made of a fiber put on a hand mold is dipped into a polyurethane resin solution containing an organic solvent with a solubility parameter of 6.0 to 10.5 in an amount of 1 to 200 parts by weight based on 100 parts by weight of the resin content, the hand mold is pulled up to remove the excessive resin solution, and the hand mold is dipped into water or warm water to cause the polyurethane resin to gel in a porous state. 
     
     
         8 . The glove according to  claim 6 , wherein the organic solvent is methyl ethyl ketone or ethylbenzene. 
     
     
         9 . The glove according to  claim 7 , wherein the organic solvent is methyl ethyl ketone or ethylbenzene.
