Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to gloves, and more particularly to non-breathable and moisture permeable gloves that are useful for various types of work, general use, leisure use, and the like. (Prior Art) A large number of gloves have been known for various types of work, general use, leisure use, cold protection, etc., and they can be broadly classified into gloves made of fibers, gloves made of synthetic leather, and gloves made of synthetic leather.
Examples include gloves made of a flexible resin such as rubber or synthetic resin as a base material, and gloves made of a combination of these fiber base materials and rubber or synthetic resin. (Problem to be solved by the invention) Fiber-based gloves are cheap and the most common, and are breathable, so even if you sweat when wearing them, they will not get stuffy. Due to its nature, it cannot be said to be sufficiently waterproof, cold-proof, or wind-proof. Therefore, there is a need for gloves that are waterproof, cold-proof, and wind-proof, and do not cause stuffiness even when sweating occurs. In addition, gloves made of leather or synthetic leather, etc.
Although they are more expensive and have higher performance than gloves made of the above-mentioned fibers as a base material, they are not compatible with the feeling of stuffiness caused by perspiration, waterproofness, and cold/windproof properties. That is, if the breathability is increased to eliminate the feeling of stuffiness, the waterproofness, cold protection, and windproofness will be reduced, while if the waterproofness is increased, the feeling of wearing will be reduced and the feeling of stuffiness will occur. In addition, so-called rubber gloves and vinyl gloves are widely used as work gloves for industrial and industrial use because they are water-proof, cold-proof, and wind-proof.
Since they are not breathable, the interior becomes stuffy due to sweating during use, significantly reducing the feeling of wearing the gloves, and there is a risk that the hands may slip inside the gloves. In addition, for industrial use, when oil resistance, solvent resistance, etc. are required, there are gloves that have excellent oil resistance etc. by selecting materials that have these properties, but they also have moisture permeability. etc. is lacking. In addition, gloves formed by combining the above-mentioned materials, for example, gloves with a fiber base material on the inside and a flexible resin layer on the surface layer, are widely used.
Even with these gloves, moisture permeability, waterproofness, cold protection, wind protection, etc. are still not compatible, as described above. As mentioned above, there are almost no known gloves that eliminate the feeling of stuffiness inside due to sweating when worn, and which are waterproof, cold-proof, and wind-proof at the same time. As mentioned above, the present invention has proposed a glove that is non-porous (that is, non-breathable and liquid-impermeable), but permeable only to moisture caused by perspiration, and has waterproof, cold and windproof properties (USSerial (See specification No. 772412). Although these gloves are made of a continuous film, they have the unique property of being able to release moisture from sweat when worn to the outside of the glove. , is only achieved satisfactorily if the coating is sufficiently thin, and has the disadvantage that moisture permeability decreases if the coating becomes sufficiently thick. Therefore, the object of the present invention is to have sufficient moisture permeability even if the film is continuous and has sufficient film thickness.
Therefore, it is an object of the present invention to provide a new glove that has sufficient waterproofness, cold protection, wind protection, etc. at the same time. The above objects of the present invention have been achieved by the present invention described below. (Means for Solving the Problems) That is, the present invention provides a glove comprising at least one flexible resin layer, wherein the flexible resin layer contains a water-absorbing resin. A breathable and moisture permeable glove and a method for manufacturing the same. Now to explain the invention in more detail, the inventors have previously discovered that by using certain materials,
We have developed a glove that has a continuous coating that is sufficiently waterproof, cold and windproof, oil resistant, etc., and that can also release moisture from sweating to the outside of the glove when worn. As the film becomes thicker, the moisture permeability decreases, and there is therefore concern about its strength. Another disadvantage is that the materials used are limited to special materials. As a result of intensive research to solve these problems, the inventors of the present invention have discovered that when a water-absorbing resin is included in a flexible resin layer for forming gloves, even if the coating is sufficiently thick, it is not sufficient. It was discovered that the gloves can maintain good moisture permeability, and that a glove that solves the above-mentioned drawbacks can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS Several examples of gloves according to the invention will now be described with reference to the accompanying drawings, in which: FIG. FIG. 1 is a diagram schematically showing a cross section of a part of the flexible resin layer of the glove of the present invention, and FIGS. 2 to 7 are diagrams diagrammatically showing a cross section of the flexible resin layer of other examples. FIG. As shown in FIGS. 1 to 7, the non-breathable and moisture permeable glove of the present invention is characterized in that at least one flexible resin layer of the layers constituting the glove contains a water-absorbing resin. For example, as shown in Figure 1, the flexible resin layer is the only flexible resin layer containing a water-absorbing resin, and as shown in Figure 2, at least one surface thereof is Those with a rough surface, those with a flexible resin layer containing a water-absorbing resin formed on a base material as shown in the third diagram, those with a base material made of fibers, and those with a porous surface. Any base material may be used, such as a foam layer, synthetic leather, or natural leather. Further, it is a matter of course that the surface thereof may be roughened as shown in the second figure. In the example shown in the fourth figure, the flexible resin layer containing the water-absorbing resin has a multilayer structure, and at least one surface of the flexible resin layer may be roughened as shown in the second figure. The example shown in Figure 5 is an example in which a flexible resin layer containing a water-absorbing resin is sandwiched by an arbitrary breathable base material such as a base material,
Further, the example shown in the sixth figure is an example in which a flexible resin layer containing a water-absorbing resin is formed on both sides of the fiber base material, etc., and the example shown in the seventh figure is an example in which a flexible resin layer containing a water-absorbing resin is formed on the fiber base material etc. This is an example in which a flexible resin containing the following is impregnated. The above examples are diagrams for explaining the structure of the glove of the present invention, and the glove of the present invention is not limited to these examples, and at least one flexible resin layer thereof is
Any gloves other than those illustrated are also included in the present invention as long as they contain a water-absorbing resin. The non-breathable and moisture permeable glove of the present invention has the structure as exemplified above, and the flexible resin is formed as a non-porous continuous film from a substantially water-insoluble flexible resin material. . Therefore, it is essentially different from porous coatings such as those produced by wet film formation of polyurethane in the prior art, and is substantially non-porous, meaning that not only gases such as air, but also water, organic solvents, etc. do not permeate. Therefore, it has sufficient waterproofness, coldproof/windproof properties, oil resistance, etc. Of course, coatings made of flexible resin alone have been known in the past, but the inventor of the present invention found that when a water-absorbing resin is included in the coating, the moisture generated by sweat inside the gloves when the gloves are worn is absorbed by the flexible resin. It has been discovered that moisture is quickly absorbed by the water-absorbing resin on the surface of the resin layer, and the absorbed moisture quickly diffuses through the flexible resin layer and is easily released from the surface of the glove. It is. The above is the basic principle of the present invention, but the moisture permeability of non-breathable and moisture permeable gloves made of a flexible resin layer containing a water-absorbing resin is shown in any of Figures 2 to 7. It has been found that by roughening at least one of the surfaces, the improvement can be significantly improved. For example, by roughening the outer surface of the glove as shown in the second figure, the rate of moisture absorption from the inside of the glove is increased several to several tens of times due to the roughened surface. (Note that in the present invention, the term "roughening" means forming any unevenness on a flat surface to enlarge the surface area.) Along with this increase in the rate of moisture release, the rate of moisture absorption on the inner surface of the glove will significantly increase if one of the resin layers is roughened, even if one of the resin layers is not roughened. It was hot. Of course, if both the inner and outer surfaces of the glove are roughened, the moisture permeability will of course be further improved. Also, the third ~
As shown in Figure 7, such surface roughening can be easily achieved by combining a flexible resin layer containing a water-absorbing resin with a base material having an uneven surface, such as a textile material. Can be done. Due to the above-described structure and effects, the glove of the present invention can exhibit sufficient moisture permeability while being non-breathable, and the flexible resin layer can be made thicker than in the prior art. However, such excellent moisture permeability can be maintained by changing the types, combinations, and relative amounts of the flexible resin and water-absorbing resin used. Preferred materials for forming the glove of the present invention as described above are described below. The flexible resin used to form the glove of the present invention includes flexible resins conventionally used for forming gloves, such as natural rubber,
Polybutadiene, butadiene styrene rubber, butadiene acrylonitrile rubber, polychloroprene, polyisoprene, chlorosulfonated polyethylene, polyisobutylene, isobutylene isoprene rubber, acrylic rubber, ethylene-vinyl acetate copolymer rubber, saponified products thereof, polysulfide synthetic rubber, urethane rubber , fluorocarbon rubber, silicone rubber, and other elastomers; soft vinyl chloride resins, polyolefin resins such as polyethylene, polypropylene, and polybutene, soft acrylic resins, polyester resins, polyamide resins, polyurethane resins, silicone resins, Any base resin or the like can be used. Preferred flexible resins in the present invention include water-insoluble flexible resins that have been partially rendered hydrophilic by conventionally known techniques among the various flexible resins mentioned above. For example, when a flexible resin such as the one described above is modified with a hydrophilic material later, or when producing a flexible resin such as the one described above, it is possible to copolymerize a part of the monomer or a part of the raw material. Examples include substantially water-insoluble flexible resins into which hydrophilic monomer units and hydrophilic segments are introduced by using hydrophilic monomers and raw materials. It has been found that by using such water-insoluble and hydrophilic flexible resins, the water-absorbing resins included in these flexible resins can further promote their hygroscopicity and moisture-releasing properties. It is something that In other words, when wearing gloves, the inside of the glove inevitably becomes a high humidity condition, but the moisture inside the glove is
Since the inner surface of the glove is hydrophilic, it is easily adsorbed to the inner surface of the glove, and since the inner layer of the glove contains a water-absorbing resin, moisture within the glove is easily absorbed by the inner layer of the glove. At this time, if the inner surface of the glove is roughened, the area for absorbing moisture will be larger, so that the moisture inside the glove will be absorbed more quickly.
As a result of the water-absorbing resin being included in the flexible resin layer of the glove, the moisture thus absorbed quickly diffuses through the flexible resin layer and migrates to the surface thereof. Normally, when gloves are worn, there is high humidity inside the gloves.
Since the humidity outside the glove is relatively low, moisture that reaches the surface of the flexible resin layer is quickly released from the surface of the flexible resin layer. At this time, if the surface of the flexible resin layer is roughened, the moisture release area will be very large, and the moisture release rate will be further increased. In this way, the glove of the present invention uses the difference between the high humidity inside the glove and the low humidity outside the glove to make the flexible resin layer of the glove moisture permeable. By forming it from a hydrophilic and water-insoluble flexible resin, its moisture permeability has become even more remarkable. The water-absorbing resin used in the present invention and which achieves the main effects of the present invention is a resin that absorbs a large amount of water when it comes into contact with water, but does not dissolve in water.
In general, highly water-soluble natural or synthetic polymers are crosslinked to make them water-insoluble, and these water-absorbing resins themselves can be manufactured using conventional technologies such as disposable diapers, water-swellable waterproof materials, water-swellable paints, These are used in the fields of soil water retention agents, etc., and any of these conventionally known water-absorbing resins can be used in the present invention. Specific examples include starch-sodium poly(meth)acrylate grafted products,
Saponified starch-polyacrylonitrile grafted product, cellulose-sodium poly(meth)acrylate, cross-linked sodium poly(meth)acrylate, cross-linked potassium poly(meth)acrylate, vinyl alcohol-sodium (meth)acrylate-(meth) ) Acrylic acid copolymer, alkali neutralized product of crosslinked isobutylene-maleic anhydride copolymer,
Examples include sodium salt of cross-linked carboxymethylcellulose and cross-linked polyethylene oxide. These water-absorbing resins have various trade names, such as Sumitomo Chemical, Kao, Sanyo Chemical, Dainichiseika,
It is readily available from P&G and other chemical companies. Any of the conventionally known water-absorbing resins as described above can be freely used in the present invention, but the most preferable for the purpose of the present invention is a fine powder of the above-mentioned water-absorbing resin, whose average particle size is 10 μm. Below, preferably 1μm or less, more preferably 0.01~
The particle size is 1.0 μm. Normally, the water-absorbing resin has poor compatibility with the flexible resin used in the present invention, but by using the water-absorbing resin as a fine powder as described above, it can be uniformly distributed in the flexible resin. Can be dispersed. A more preferred water-absorbing resin in the present invention is a water-absorbing resin composed of a hydrophilic segment and a hydrophobic segment, and such a water-absorbing resin has the flexibility due to the presence of the hydrophobic segment therein. It is possible to provide gloves that are uniformly dispersible in the plastic resin and have high moisture permeability. Such block copolymer type water-absorbing resins are available under the trade name "Dicewell" with various water absorbencies from Dainichiseika Kagyo Co., Ltd., and all are useful in the present invention. The above-mentioned water-absorbing resin is used in the production of gloves in an amount of 0.1 to 100 parts by weight per 100 parts by weight of flexible resin.
It is preferably used in an amount of 1 to 30 parts by weight. If the amount used is too small, moisture permeability, which is the main objective of the present invention, will not be sufficiently achieved, and if the amount used is too large, the flexibility of the flexible resin will be insufficient, which is not preferable. The non-breathable and moisture-permeable glove of the present invention is characterized by having a flexible resin layer made of the above-mentioned flexible resin and a water-absorbing resin, and of course contains the above-mentioned water-absorbing resin. The flexible resin layer contains conventionally known additives such as colorants, softeners, plasticizers,
Of course, antistatic agents, stabilizers, fillers, etc. may also be optionally included. The non-breathable and moisture permeable gloves of the present invention are provided by several preferred methods as follows. (1) Prepare a flexible resin solution by dissolving flexible resin in a suitable solvent and uniformly dispersing fine particles of water-absorbing resin therein. A flexible resin layer containing a water-absorbing resin is formed by applying the solution to a shaped handprint or immersing the handprint in this solution to provide a solution layer on the surface of the handprint, and removing the solvent using an appropriate method. A method of forming and obtaining the breathable and moisture permeable gloves of the present invention. The solvent used in this method is a solvent that dissolves the above-mentioned flexible resin, and such solvents include hexane, hexane,
Methylpentane, heptane, octane, nonane, decane, benzene, toluene, xylene,
Hydrocarbon solvents such as tetralin and alkylbenzene, mixed solvents such as industrial gasoline, petroleum ether, petroleum naphtha, and kerosene, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, trichloroethane, trichlorethylene, perchlorethylene, chlorobenzene, Halogenated hydrocarbon solvents such as dichlorobenzene, chlorotoluene, freons, methyl alcohol, ethyl alcohol, propyl alcohol, butyl alcohol,
Alcohol solvents such as amyl alcohol, ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, glycerin, benzyl alcohol, cyclohexanol, tetrahydrofurfuryl alcohol, ether solvents such as methyl cellosolve, ethyl cellosolve, butyl cellosolve, diethyl carbitol, dioxane, etc. Solvents, ketone solvents such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, acetophenone, ester solvents such as ethyl acetate, butyl acetate, cellosolve acetate, other acetic acid, furfural, acetonitrile, formamide, dimethylformamide, carbon disulfide, sulfolane , dimethyl sulfoxide, N-methylpyrrolidone, etc., or mixtures thereof. A solution of the flexible resin used in the present invention is obtained by preparing a solution by selecting a solvent that dissolves the flexible resin from the solvents mentioned above, and dispersing the water-absorbing resin therein. The flexible resin solution is about 5~
A concentration of 50% by weight is good, and the amount of water-absorbing resin to be dispersed is 0.1 to 100 parts by weight of the flexible resin used.
Add at a rate of 100 parts by weight. It is preferable to disperse the water-absorbing resin as finely as possible in advance in a suitable solvent using a ball mill, sand mill or other suitable grinding method, and then add this dispersion to the flexible resin solution. The hand mold used in the present invention may be any hand mold as long as it is made of a material that is inert to the above-mentioned solvents, and is preferably made of ceramic or metal, for example. Any method may be used to apply the flexible resin solution containing the water-absorbing resin to the surface of such a hand mold, but a preferred method is to immerse the hand mold in a flexible resin solution and pull it. This is a way to raise it. At this time, it is preferable to slowly rotate the hand mold so that the flexible resin solution on the surface of the hand mold is evenly distributed. In addition, when applying the resin solution, in order to make it easier to peel off the film after film formation, a release agent may be applied to the surface of the hand mold in advance, or a poor solvent may be used that will precipitate the flexible resin in the solution. It is also preferable to apply. Next, as a method for removing the solvent from the resin solution layer applied to the surface of the hand mold, there is a method of removing the solvent by heating (dry method) and a method of removing the solvent from the resin solution layer applied to the surface of the hand mold, and a method of removing the solvent by heating (dry method), and a method of removing the solvent from the resin solution layer applied to the surface of the hand mold. Preferred are a method in which the solvent is extracted by immersion in a solvent that is miscible with the solvent in the solution (wet method), and a method in which both of these methods are combined. When using the above-mentioned wet method, care must be taken because the formed film may become porous and breathable like conventional synthetic leather. By utilizing the dry method, a non-breathable and moisture permeable glove of the present invention having a smooth surface as shown in the first figure can be obtained. In this case, by forming an uneven pattern on the surface of the hand shape in advance, a non-breathable and moisture permeable glove with a roughened inner surface can be obtained. In addition, if a poor solvent is applied to the surface of the hand mold in advance, the flexible resin will precipitate on the surface of the hand mold at the same time as the solution is applied. is obtained. Alternatively, the above dry method and wet method may be combined, for example, first applying a poor solvent to the resin solution on the hand mold to roughen only the surface, then using the dry method,
By removing the solvent, a non-breathable and moisture permeable glove with a roughened surface is obtained as shown in the second figure. Alternatively, a glove with a smooth surface as shown in the first figure is first formed as described above, and then the same or different resin solution is applied to the surface,
Then, if a film is formed by a wet method as described above,
A glove with a roughened outermost surface can be obtained. As described above, FIGS. 1 and 2 of the present invention,
A non-breathable and moisture permeable glove of the present invention consisting only of a flexible resin layer containing a water-absorbing resin as shown in Figure 4 is obtained, but the thickness of the coating of this glove is
By changing the concentration and viscosity of the resin solution used, the thickness can be changed from a few μm to several tens of μm, and the film formation process involves applying the resin solution to the hand mold and removing the solvent. By repeating this process multiple times, thick gloves ranging from several tens of micrometers to several millimeters can be formed. The most remarkable effect of the present invention is that it is possible to provide non-breathable and moisture-permeable gloves that have sufficient moisture permeability even as thick gloves. That is, according to the technique previously proposed by the present inventor, gloves with sufficient moisture permeability can be provided when the thickness is from several μm to 10-odd μm, but in this case, it is necessary to increase the thickness of the coating. As the thickness increases, the moisture permeability decreases as the thickness increases.
If the thickness exceeds 100 μm, there is a drawback that almost no moisture permeability is achieved, so it has been impossible to provide gloves with high moisture permeability, thick thickness, and excellent strength.However, in the present invention, such problems have been fully solved. In other words, by including a water-absorbing resin in a flexible resin, it does not exhibit any breathability, but even when you sweat while wearing gloves, the moisture generated is absorbed into the flexible resin containing the water-absorbing resin. Since the moisture absorption capacity of the flexible resin layer is significantly increased, even if the thickness is increased, the moisture permeability does not decrease at all, but rather improves, resulting in high moisture permeability. This simultaneously satisfies the requirements of high physical strength and high physical strength. (2) A method in which a breathable base material made of fibers or the like, for example, a base glove made of knitted fabric, etc. is attached in advance to the surface of the hand mold, and the above method (1) is carried out using this as the hand mold. According to this method, the inner side of the glove is made of, for example, a fiber base material, so it is very comfortable to wear, has high strength, and has the excellent non-breathable and windproof properties of the present invention that are waterproof, cold and windproof at the same time. Breathable gloves are provided. Furthermore, the glove of the present invention, which is formed only from a resin containing a water-absorbing resin, has the disadvantage that the glove itself expands if it is immersed in water for a long time. In this case, since the base material is non-expandable, the resin layer expands and becomes thicker, but the size does not change. The base gloves used in this method are generally woven or knitted gloves made of natural fibers such as cotton, synthetic fibers such as polyester, polyamide, acetate, polyacrylic, etc.; Gloves made of leather or the like can also be used. One of the great advantages of this method is that, as shown in Figure 4, since the base glove itself is roughened, the flexible resin formed on the surface of the base glove Since the inner surface of the layer is necessarily roughened, a non-breathable and moisture permeable glove with very high moisture permeability is provided, and a flexible glove formed as in the method (1) above is also advantageous. By simultaneously roughening the outer surface of the polyurethane resin layer, it is possible to provide a glove with even better moisture permeability. Furthermore, according to this method, the flexible resin in the resin solution is precipitated on the surface of the base glove by impregnating the base glove attached to the hand shape with a flexible resin phagocytic agent in advance. Therefore, to provide a non-breathable and moisture permeable glove of the present invention which can further promote surface roughening and has excellent texture by preventing excessive impregnation of the resin solution into the base glove. Can be done. (3) Prepare a flexible resin film containing a water-absorbing resin and having any thickness in advance, stack two sheets of this film, cut them into a hand shape, and bond the ends together to make gloves. Method. In this method, only the back side or palm side of the glove is made of a flexible resin film containing a water-absorbing resin, and the other parts may be made of a general moisture-impermeable film. In this method, thermoplastic resins that are difficult to dissolve in solvents, such as polyolefins such as polyethylene and polypropylene, polyesters, and polyamides, can be easily used. That is,
Knead the required amount of water absorbent resin into flexible resin,
This is because a flexible resin film containing a water-absorbing resin can be easily formed using general film-forming techniques such as a T-die method, an inflation method, and a calendar method. (4) When using polyvinyl chloride resin as a flexible resin, a paste sol or organosol in which the polyvinyl chloride resin is dispersed in a liquid plasticizer is used to perform the above (1) to (3). How to apply the method. According to this method, it is only necessary to add an appropriate amount of water-absorbing resin to a commercially available paste sol or organosol and carry out the methods (1) to (3) above, and there is no need to use much solvent, so it is cost-effective. This is extremely advantageous. The non-breathable and moisture permeable glove of the present invention has the above-described structure and is provided by the above-described method. There are some fields where adhesion of moisture (sweat) released from fingertips, palms, etc. is disliked, and when gloves are used for such purposes, the fingertips, finger portions, or palm portions of the gloves of the present invention must be Preferably, a moisture-impermeable coating is applied to the part. By forming a moisture-impermeable layer in necessary areas in this manner, there is no risk of contaminating the object with moisture even if the object is touched with the fingertips of the glove. Such a moisture-impermeable layer can be formed by immersing the moisture-permeable glove of the present invention in a flexible resin solution (not containing a water-absorbing resin) in only the necessary portion, pulling it out, and drying it, or It can be formed by any method such as applying a solution to the required area with a brush or spray and drying it. The thickness of the moisture-impermeable layer formed may be any thickness, but is generally about 0.1 to
It is about 100 μm. (Function/Effect) According to the present invention as described above, liquids such as water, oil, or organic solvents, and gases such as air are not substantially allowed to pass through, and moisture generated by sweating when worn is quickly absorbed, and the gloves A non-breathable and moisture permeable glove is provided that allows moisture to evaporate to the outside. Further, according to the present invention, the problem of the conventional technology that moisture permeability is lost when the thickness of the flexible resin layer is increased is solved, and the flexible resin layer is non-breathable and moisture permeable, which is thick and has high moisture permeability. Gloves will be provided. The gloves of the present invention as described above are suitable for general use, industrial use,
It is useful for various uses such as work use and leisure use. Next, the present invention will be explained in more detail with reference to Examples.

The thickness of this layer was approximately 3 μm. This glove had sufficient moisture permeability, and even when the object was picked up with the fingertips, moisture did not adhere to the object at all. Example 7 In Example 6, a polyurethane solution was applied to the palm of the glove using a brush, and a moisture-impermeable layer was formed on the palm in the same manner. The thickness of this layer is approximately 5μ
It was m. Even if this glove was used to grasp an item that does not like moisture to adhere to it, no moisture would adhere to the item, and since the back of the hand was sufficiently moisture permeable, the glove as a whole exhibited sufficient moisture permeability. Comparative Example In Example 1, a resin solution was prepared in the same manner as in Example 1 except that the water-absorbing resin was not used, and these solutions were used.
Comparative gloves corresponding to the gloves of the present invention were manufactured in the same manner as in Example 5. Evaluation Example When the gloves of Examples 2 to 5 and Comparative Example were filled with water and left for 30 minutes, no water leakage occurred from any of the gloves. Next, after thoroughly drying these gloves, put on the corresponding gloves on both hands, seal the wrists of both gloves, and perform light work for 1 hour in a room adjusted to a temperature of 30℃ and a relative humidity of 70% RH. As a result, the gloves of the present invention hardly felt stuffy even after one hour, whereas the gloves of the comparative examples all felt stuffy after one minute, and the inside became wet after 10 minutes. After another 30 minutes, sweat had accumulated inside and it became slimy.
