Benefits of technology

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 prese

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 o

example 1

100 parts (resin portion 30 parts, DMF 70 parts) of a polyurethane resin for wet processing “CRISVON 8006HVLD (produced by DIC Corporation)” and 200 parts of N,N-dimethylformamide (DMF) were mixed to prepare a polyurethane resin solution.

A seamless knitted glove knitted with woolly nylon yarns using a 13 gauge knitting machine was used as a raw glove, and the glove was put on a hand mold for dipping and the glove put on the hand mold was gradually dipped into the above-mentioned raw material solution to allow the polyurethane resin solution to adhere to the raw glove while impregnating the raw glove with the polyurethane resin solution, and then the hand mold was pulled up slowly and the excessive resin solution was removed through dripping of the solution. Next, the hand mold was dipped into warm water of 60° C. in which methyl ethyl ketone (MEK) (SP value: 9.3) was mixed in the proportion of 5% by weight (extraction solution, the same applies hereinafter) for 60 minutes to perform...

examples 2 to 4

Working gloves were obtained by following the same procedure as in Example 1 except for changing the kind and the amount used of the hydrophilic solvent as shown in Table 1.

Production conditions of the gloves, characteristics of the coating layer and physical properties of the gloves are shown in Table 1. Further, with respect to a middle finger of the obtained gloves, measurement data of an area of a pore, a thickness of a resin layer between pores for the respective pores, a void ratio and the number of pores are shown in Table 3.

In the obtained gloves, a gelation rate of the polyurethane resin became slower than usual due to n-hexane, ethylbenzene and methyl acetate, which were added to warm water, and consequently, in the glove in Example 2, with respect to the porous structure of the coating layer, the area (size) of a pore included that of 13.36 to 77.05 μm2 and an average of the thickness of a resin layer between pores was controlled to 4.2 μm. Furthermore, the void ratio was...

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,...
