Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a double glove having solvent resistance and gas barrier properties, and more particularly to a double glove in which the inner glove does not turn over when the glove is pulled out.

[0002]

[Prior art]

 Conventionally, in various medical institutions such as laboratories, manufacturing plants, and hospitals related to precision electronic components, the safety of workers and the prevention of contamination of products, and the safety of doctors and patients From the viewpoint of hygiene and the like, various types of work gloves manufactured by stacking polymer films such as polyethylene, polypropylene and polyurethane films and fusing them into bills are used.

However, these polymer film gloves cannot block the vapor of the organic solvent, and use ethylene-vinyl alcohol copolymer resin (hereinafter abbreviated as EVOH) having excellent gas barrier properties. Use was suggested. However, although EVOH has excellent gas barrier properties, it is inferior in water resistance, and its film is hard and brittle, has insufficient elasticity, and has insufficient tear strength. Was difficult to construct.

The present inventor has proposed a utility model registration No. 3075245 in order to solve the problem of the above-mentioned conventional gas barrier gloves. The content of this proposal is that in a double glove consisting of an outer glove and an inner glove, the outer glove and the inner glove are integrated at the cuffs, and the inner glove has an EVOH film inserted between the polyethylene film and the woven or nonwoven fabric. The outer glove is formed of a polyurethane or silicone-based polymer.

[0005]

[Problems to be solved by the invention]

 The double gloves proposed above are excellent, but when the sweated hand is pulled out, the inner glove may be turned inside out and pulled out of the outer glove. It is possible to return the inverted inner glove to its original state, but it is very complicated at the fingertip. Such a problem can be easily solved by bonding the inner glove and the outer glove to each other with an adhesive at their fingertips. However, such bonding makes the fingertip that requires an excellent tactile stiffness hard. However, there was a problem that workability was reduced. Accordingly, an object of the present invention is to provide a double glove in which an inner glove composed of a three-layer film sandwiched by an EVOH film does not turn over when the glove is pulled out.

[0006]

[Means for Solving the Problems]

 The above object is achieved by the present invention described below. That is, the present invention provides a double glove comprising an outer glove and an inner glove, wherein the inner glove has a three-layer structure in which an ethylene-vinyl alcohol copolymer film is inserted between a polyethylene film and a woven or nonwoven fabric. The outer glove is made of polyurethane or silicone-based polymer, and the inner glove is provided with a non-slip member on at least a part of its surface. provide.

[0007]

[Embodiment of the invention]

 Next, the present invention will be described in more detail with reference to preferred embodiments. FIG. 1 is a schematic view illustrating the double glove of the present invention. A is a diagram showing an outer glove, and B is a diagram showing an inner glove having a non-slip member C formed on the surface. FIG. 2 shows the appearance of the inner glove in another embodiment, and FIG. 3 is a diagram showing a double glove in which the inner glove B is inserted into the outer glove A and the entire cuff is integrated. FIG. 4 is a partially enlarged view of a cross section taken along the line XX ′ of FIG. 3. The inner glove B is made of a three-layer film, and the side 2 that contacts the inner surface of the outer glove A is made of polyethylene. The inner surface 4 of the film and the inner glove B is a woven or non-woven fabric, and has a three-layer structure in which a gas barrier EVOH film 3 is inserted between them. Is formed with a non-slip member C 1. Reference numeral 1 denotes a polyurethane film constituting the outer glove A.

[0008] The present invention is characterized in that the anti-slip member C is formed on at least a part of the surface of the inner glove in the double glove as described above. When such a non-slip member C is formed on the surface of the inner glove, the inner glove is inserted into the outer glove, and the cuffs of both are sewn together. Since a frictional force greater than the frictional force with the inner surface is generated between the inner surface of the outer glove and the outer surface of the inner glove by the non-slip member C, the inner glove B is moved from the outer glove A with the hand withdrawal. It cannot be pulled out and turned inside out. Of course, if the inside of the glove is contaminated, it is possible to forcibly pull out the inner glove B to remove the contamination and restore it. In addition, although the drawing shows an example in which the non-slip member C is formed on the surface of the upper part of the inner glove for convenience of explanation, the non-slip member is not limited to the upper part and may be provided on the palm side. Of course, it may be provided on both, or may be provided on the whole.

The above-mentioned non-slip member C is preferably formed of a soft material such as a sponge, a resin foam, or a rubber foam so as not to give a feeling of strangeness when working with gloves. The size of the non-slip member C is not particularly limited, but may be, for example, a strip having a thickness of about 1 to 8 mm (FIGS. 1 and 2a), or as shown in FIG. It may be provided in some way. Considering the cost, it is preferable that the shape is a long strip in the fingertip direction. The non-slip member C can be fixed with a soft adhesive or a double-sided adhesive tape.

[0010] In the above-mentioned three-layer film used for forming the inner glove B, the respective layers may be adhered with an appropriate adhesive or may not be adhered. The inner glove B is formed by laminating films having a three-layer structure and fusing them into bills, but may be formed by other methods. The thickness of each film and woven or nonwoven fabric is not particularly limited, but is usually about 0.001 to 0.5 mm in consideration of gas barrier properties, strength, feeling of wearing, or usability.

On the other hand, the outer glove A is made of polyurethane. As the polyurethane, it is preferable to use polyurethane having solvent resistance and flexibility. For outer gloves, usually, a hand mold made of metal such as aluminum or ceramics is dipped in a polyurethane solution or an aqueous dispersion (emulsion), pulled up, and dried or solidified to form a polyurethane film. It is formed by peeling from the mold. The thickness of the polyurethane coating is usually about 0.2 to 0.5 mm. If necessary, the hand mold may be covered with a thin glove of an arbitrary material such as fiber, and a polyurethane film may be formed thereon.

Using the inner glove B and the outer glove A prepared in this manner, and inserting the inner glove B into the outer glove A, the double glove of the present invention is configured. In the present invention, the cuffs of the inner glove and the outer glove may or may not be integrated. Preferably, part or all of the cuffs of the inner and outer gloves are integrated. The method of integration is not particularly limited, and may be any method such as bonding, fusion, or suturing. By design, the entire cuff can be bordered with synthetic leather or other material (see Fig. 3). As described above, in the double glove of the present invention, the inner glove B and the outer glove A are formed in a free state except for the cuffs. The outer glove A and the inner glove B in FIG. 4 may be in close contact with each other, but the one without contact is more flexible as a whole.

[0013] The film forming material of the three-layer structure constituting the inner glove B is a woven or non-woven fabric made of various fibers on the side where the hand is inserted, which improves the feel to the skin and the overall strength. Improve. Preferred materials include a nonwoven fabric formed by bonding polyethylene or polypropylene short fibers by fusion, and a nonwoven fabric formed by bonding with a binder resin. On the other hand, the side in contact with the inner surface of the outer glove is a low-density or high-density polyethylene film, and an additive such as a filler such as calcium carbonate can be appropriately added to the polyethylene.

The EVOH film inserted between the woven or nonwoven fabric and the polyethylene film is a saponified film of an ethylene-vinyl acetate copolymer, and the EVOH has an ethylene content of 20 to 60. It is preferable that the mole percent is a saponified product of vinyl acetate units, with the balance being 80% or more, more preferably 90% or more. Such an EVOH can be obtained, for example, as a resin such as EVAL EP-F101, EP-H101, EP-E105, EP-G110 manufactured by Kuraray Co., Ltd., or as a film of various grades. When the three-layer film is a three-layer laminated film in which an EVOH film is bonded to a polyethylene film and a woven or nonwoven fabric, ADMER manufactured by Mitsui Petrochemical Co., Ltd. and Mitsubishi Chemical Co., Ltd. A laminated film can be obtained by co-extrusion using an adhesive resin such as MODIC.

As the polyurethane forming the outer glove A, any polyurethane having solvent resistance and excellent flexibility can be used, and is not particularly limited. For example, a polyurethane solution called Rezamine or the like manufactured by Dainichi Seika Kogyo Co., Ltd. can be obtained and used. Also, when the gloves of the present invention are used by immersing them in a good solvent of polyurethane such as DMF, polyurethane has a problem in solvent resistance. In such a case, the outer gloves are made of a silicone polymer. It is formed. As the silicone polymer, those conventionally used in the production of medical gloves and the like can be used, and are not particularly limited. The thickness of the silicone polymer film is the same as that of polyurethane.

【Example】

 Next, the present invention will be described more specifically with reference to examples. Example 1 As an inner glove, a commercially available glove capable of being inserted into a half of an arm by fusing a hand-printed three-layer structure film (total thickness: 0.1 mm) of polyethylene film / EVOH film / polyethylene nonwoven fabric was prepared. On the other hand, Rezamin Cu-4210 (manufactured by Dainichi Seika Kogyo Co., Ltd .: solid content 30% by weight) was used as a polyurethane solution, and a ceramic mold was immersed and pulled up, dried, and dried to form an arm having a thickness of about 0.2 mm. An outer glove that can be inserted up to half of the size was prepared. As shown in FIG. 1, a rubber sponge having a thickness of 5 mm, a length of 50 mm and a width of 15 mm was fixed to the surface of the back of each finger of the inner glove with a double-sided adhesive tape. Insert the inner glove into the outer glove made of polyurethane, align the cuffs of the inner glove and the outer glove, border the entire cuff with a band of polyurethane synthetic leather, and sew it together with a sewing machine to integrate. Obtained heavy gloves.

The operation of wearing the double gloves described above, immersing them in toluene at room temperature for 30 seconds, pulling them up and allowing them to stand for 5 minutes was repeated 10 times, and the hands were pulled out to remove the gas barrier property from the odor of the hands. As a result, no permeation of toluene vapor was observed. In addition, the operation of holding and moving polyethylene beakers of various capacities was repeated, but there was no problem in handling. The feeling of wearing was good even though the overall thickness increased compared to when the above inner gloves were worn. Furthermore, even if a wet hand was inserted into the glove and the hand was pulled out, the inner glove was not pulled out and turned over.

[0018]

[Effect of the invention]

 According to the above-described present invention, when the sweated hand is pulled out from the double glove, the problem that the inner glove is pulled out from the outer glove and turned inside out has been solved. Heavy gloves are provided.
