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 μm2 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.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a glove in which the surface of a glove made of fibers is coated with a porous layer, and more specifically, to a glove which, by controlling the porous layer, has excellent abrasion resistance, moisture permeability and flexibility and is superior in the peel strength of the porous layer.2. Description of the Related ArtHitherto, gloves, in which a resin layer or a rubber layer is provided on a part, for example, a palm part, or an entire area of a raw glove (a glove which is a base to be coated with a resin) comprised of a glove made of fibers for the purpose of anti-slip or prevention of accidents, have been known. In recent years, gloves, having a structure in which a resin layer or a rubber layer is porous particularly in order to prevent steamy conditions at the time of wearing the gloves and thereby sweat is released out of the glove, have been widely used.As gloves of this type, for example,...

AI Technical Summary

Benefits of technology

In view of the above problems, it is an object of the present invention to provide a glove which is formed by providing a porous coating layer on the surface of a raw glove comprised of a glove made of fibers, and which, by controlling a porous structure of the porous coating layer, has excellent abrasion resistance, moisture permeability and flexibility and is superior in the peel strength of the porous coating layer and in the resistance to peeling / migration to pressure-sensitive adhesive tapes or the like.

The glove of the present invention has excellent abrasion resistance, moisture permeability and flexibility, and is superior in peel strength of a porous coating layer and in resistance to peeling / migration to pressure-sensitive adhesive tapes or the like by forming a specific porous structure in which in a specific electron-microscopic field of the porous coating layer provided on the surface of a glove made of a fiber, a plurality of pores having an area of 0.785 to 78.5 μm2 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.

Further, a void ratio of the total area of pores having the area of not less than 0.785 μm2 to an area of the electron-microscopic field is preferably 0.3 to 75%, and thereby the above-mentioned effects are achieved more effectively.

Further, a number of pores having the area of 0.785 to 78.5 μm2 in the electron-microscopic field is preferably 2 to 35, and thereby the above-mentioned effects are achieved more effectively.

The glove of the present invention can be obtained by dipping a glove made of a fiber put on a hand mold into a polyurethane resin solution, then pulling up the hand mold to remove the excessive resin solution, and dipping the hand mold 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.

Further, the glove of the present invention can be obtained by dipping a glove made of a fiber put on a hand mold 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, then pulling up the hand mold to remove the excessive resin solution, and dipping the hand mold into water or warm water to cause the polyurethane resin to gel in a porous state.

Problems solved by technology

However, in gloves in which a thermoplastic resin is mechanically foamed like those described in JP-A Nos. 2006-169676 and 2005-320352, there is a problem that a size of pore of the foam is large and therefore the resin is exfoliated due to a frictional force applied to the glove at the time of working, and there are problems that an amount of the resin is large and therefore the function of releasing sweat is low and a thickness of the glove is large.

Further, in the glove described in JP-A No. 2005-054329, there are problems that the glove is vulnerable to abrasion because of less amount of the resin provided on the surface of the glove and that because of insufficient peel strength, the resin adheres to a pressure-sensitive adhesive tape or a seal in works to handle the pressure-sensitive adhesive tape or the seal, for example packaging works, and the resin layer is peeled off to migrate to the pressure-sensitive adhesive tape or the seal.

Further, a part of the coating layer of the glove may sometimes migrate to precision products or the like to cause problems.

Further, in the glove described in International Publication WO 2008 / 029703, since a porous polyurethane resin is coated with nonporous polyurethane, it is inevitable that the moisture permeability is poor even if a moisture-permeable resin is used.
