Description

  The present invention relates to a glove that uses polyethylene and is excellent in slip resistance.

  Conventionally, as a working glove made of synthetic resin for disposable use, two sheets of synthetic resin film such as polyethylene, polyvinyl chloride, ethylene-vinyl acetate copolymer or polypropylene are overlapped, cut into a glove shape, and opened. The glove is manufactured by welding two films to each other by heat sealing at the peripheral edge of the cut, leaving the part. Among the above, single-layer polyethylene films such as low-density polyethylene films and high-density polyethylene films lack film elongation and film strength, and the film is too stiff, resulting in a sense of incongruity at the time of wearing and lack of fit to the hand. Since polyvinyl chloride contains chlorine, there is a problem of environmental pollution such as generation of dioxins during incineration. Furthermore, ethylene-vinyl acetate copolymer films and polypropylene have problems such as insufficient film elongation and film strength and high price.

  In addition, gloves may be made from two thermoplastic polyurethane films by the same manufacturing method as described above. Thin film gloves made of polyurethane film have adhesiveness on both the inner and outer surfaces, and have the advantage of being hard to slip off when gripping an article, but the adhesiveness related to stickiness on the skin of a person when releasing the gripped article is a drawback. Become. As for gloves related to polyurethane films, a glove having an adhesive surface on the outer side and good gripping property of the article and an inner side having slipperiness on the skin is disclosed (Patent Document 1). In Patent Document 1, a uniform mixture of a thermoplastic polyurethane resin capable of forming a film, a fine inorganic filler having an average particle size in the range of 0.5 to 5 microns, and a lubricant composed of a carboxylic acid amide derivative is formed by inflation molding. A film (a) produced by the method, having a large number of fine protrusions on both surfaces and having both surfaces slidable against human skin, is a thermoplastic having film-forming ability. It is assumed that a polyurethane two-layer joining film obtained by laminating on a film (b) made of polyurethane resin and having a flat surface sticking to human skin and integrated by thermal joining is obtained. Is formed on a glove or finger sack by a method in which these two sheets are overlapped and cut into a hand shape or finger sack shape, and the periphery is heat-sealed.

  Furthermore, Patent Document 2 discloses a base layer composed of a cut-resistant yarn, an intermediate layer composed of natural fibers, as a cut-resistant and liquid-impermeable composite material that can be used to form a protective cloth such as gloves. It provides a protective material composed of a layer and an outer layer composed of a flexible, liquid impervious elastomeric material, providing a non-slip, gripping surface.

  However, the synthetic resin glove according to the above patent document has the following problems.

  1stly, about the glove which concerns on patent document 1, as a chemical property, a polyurethane is easy to progress over time of a raw material, and has difficulty in long-term storage after commercialization.

  2ndly, about the glove which concerns on patent document 2, the laminated structure of a synthetic resin is complicated, and cost starts.

  In view of the above problems, an object of the present invention is to provide a glove that uses a polyethylene resin and is excellent in slip resistance at low cost.

  In order to achieve the above-mentioned object, the present inventor, as a result of intensive studies, uses a specific polyethylene-based resin to provide an adhesive having high film strength and heat-seal strength, and having low adhesiveness that could not be achieved conventionally. It has been found that the above problems can be solved by a glove made of a film having a layer, and the present invention has been completed.

  That is, the polyethylene glove of the present invention is a pressure-sensitive adhesive layer made of linear low-density polyethylene, and a base layer made of polyethylene of any one of low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, or high-density polyethylene, It is characterized by comprising a laminated sheet having a structure obtained by thermocompression bonding.

  Further, an intermediate layer made of high-density polyethylene may be interposed between the base layer and the adhesive layer.

  The adhesive film layer may be a metallocene catalyst-based linear low-density polyethylene polymerized using a metallocene catalyst with a saturated hydrocarbon as a solvent, or may contain an acrylic or silicone-based adhesive. . Furthermore, the base layer and / or the pressure-sensitive adhesive layer may be embossed on the surface that is not laminated.

  The glove according to the present invention has anti-slip properties, so that operability is improved and it is suitable for long-time wearing. Since it can be washed with water, it can be used repeatedly several times. It is particularly useful as a simple and hygienic glove for medical use and clean room use.

It is the schematic which shows the type | mold of the glove of Example 1 of this invention. It is a schematic sectional drawing which shows the structure of the laminated body used for manufacture of the glove of Example 1 of this invention. It is a schematic sectional drawing which shows the structure of the laminated body used for manufacture of the glove of Example 2 of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same number is attached | subjected to the same part, and the overlapping description is abbreviate | omitted. It should be noted that the drawings may be exaggerated to understand the present invention, and are not necessarily shown to scale. In addition, this invention is not limited to embodiment shown below.

  Example 1 will be described in detail with reference to the drawings.

  FIG. 1 is a schematic view showing a mold of a glove 1 according to Embodiment 1 of the present invention. In manufacturing the glove 1, the size of the glove 1 is determined so that the size of the glove 1 is slightly larger than the S, M, and L sizes, and the wrist portion is narrowed down, the finger length, It can design by selecting an opening angle etc. suitably. And the glove 1 which concerns on this invention heats the outer periphery of a hand shape, and the wrist part was open | released. In addition, the glove 1 according to the present invention is obtained by stacking two films to be described later, then heat-sealing (thermally welding) the outer periphery into a glove shape and cutting the outside of the heat-welded part. It is done. Here, you may perform what is called thermal fusing which performs heat welding and a cutting | disconnection simultaneously. The conditions for heat welding are not particularly limited, and conventionally known conditions can be appropriately employed. However, the temperature is preferably 120 to 250 ° C., the pressure is 1 to 10 kg / cm 2, and the welding time is about 0.1 to 1 second. The wrist portion may be left in advance and thermally welded to be an open mouth, but the entire outer periphery of the handprint may be heat welded and cut with scissors during use to be an open mouth.

  Please refer to FIG. FIG. 2 is a schematic cross-sectional view showing the configuration of the laminate used for manufacturing the glove 1 of Example 1 of the present invention. That is, the laminated film constituting the glove 1 of the present invention is an adhesive layer 10 made of linear low-density polyethylene and any one of low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, or high-density polyethylene. It is the structure which heat-pressed the base layer 11 which consists of polyethylene. In addition, although the thickness of a film is not specifically limited, Preferably it is 10-150 micrometers, Most preferably, it is 15-130 micrometers. If the thickness of the film is less than the above range, the film is easily broken, while if it exceeds the above range, the workability tends to be reduced, and the production cost is increased.

  The base layer 11 is made of polyethylene such as low density polyethylene, linear low density polyethylene, medium density polyethylene, and high density polyethylene, and preferably has a density of 0.945 g / cm 3 or less and a melt index of 0.1 to 10 g / 10 min. The base layer 11 is particularly preferably low density polyethylene. Low density polyethylene has excellent extrusion characteristics and heat sealability, and is flexible, waterproof, and moisture-proof.

  The adhesive layer 10 is preferably a metallocene catalyst-based linear low density polyethylene polymerized using a saturated hydrocarbon as a solvent and a metallocene catalyst. Linear low density polyethylene has self-adhesiveness. That is, linear low density polyethylene is effective for gripping and releasing glass articles such as test tubes and beakers because it is slightly sticky and easily peelable. Moreover, it is suitable for glove manufacture that it is excellent in heat-sealability and tensile strength. Moreover, in order to adjust the adhesiveness of an adhesion layer, you may use an adhesive, but a slightly adhesive acrylic type or silicone type adhesive is suitable.

  Moreover, an embossing process can be given to a film original fabric as needed. In the embossing, a film is pressed between a chill roll and a pressure roll having an appropriate surface roughness, and a concavo-convex pattern is imparted to one or both sides of the film. By embossing, not only the appearance of the film is beautiful and the product value is improved, but also when used as a glove, it is easy to grasp an object due to the unevenness of the surface, and also has an effect of preventing blocking between films. In addition, since the touch is good and there is no sticky feeling, a pleasant touch is obtained, and since the slipperiness with the hand is good, the film does not adhere to the hand and the workability at the time of wearing is rather high. Examples of the embossing include turtle shell, lattice, silk, diamond, iridescent, hemp, satin, and splash, and any of them may be used. The emboss depth (measured in accordance with JIS-B0601) is 2 to 300 μm, more preferably 40 to 180 μm. If the embossing depth is less than the above range, the effect of embossing cannot be obtained. On the other hand, if the embossing depth exceeds the above range, the heat sealability deteriorates and the appearance also gives a rough feeling.

  Manufacture of the glove 1 according to the present invention is performed using a conventional apparatus that is normally used. That is, in the laminated sheet having a two-layer structure according to Example 1, two laminated sheets with the adhesive layer 10 on the outside and the base layer 11 on the inside are used, and a high-frequency werder equipped with the mold of the glove 1 is used. It is preferable to perform fusion bonding and cutting by melting the laminated sheet at the same time, and then forming the insertion part of the hand by cutting. The glove 1 of the present invention thus obtained has high slip resistance, is not slippery, and has excellent hand fit.

  Example 2 will be described in detail with reference to the drawings. Detailed descriptions of the same contents as those in the first embodiment are omitted.

  FIG. 3 is a schematic cross-sectional view showing the configuration of the laminate used for manufacturing the glove 2 of Example 2 of the present invention. That is, the laminated film constituting the glove 2 of the present invention is an adhesive layer 20 made of linear low density polyethylene and any one of low density polyethylene, linear low density polyethylene, medium density polyethylene or high density polyethylene. It has a three-layer structure in which the base layer 21 made of polyethylene and the intermediate layer 22 made of high-density polyethylene are thermocompression-bonded between the base layer and the adhesive layer.

  The intermediate layer 22 interposed between the base layer 21 and the adhesive layer 20 is preferably made of high-density polyethylene obtained by polymerizing ethylene in the presence of a chromium oxide-based catalyst under low pressure or medium pressure conditions. The reason why the three-layer structure is formed by adding the intermediate layer 22 to the two-layer structure shown in the first embodiment is to add rigidity to the glove. High-density polyethylene is excellent in tensile strength and impact resistance and also in rigidity.

  As mentioned above, although preferred embodiment in the example of composition of the glove of the present invention was illustrated and explained, it will be understood that various changes are possible without departing from the technical scope of the present invention.

  Since the gloves of the present invention are inexpensive, hygienic and can be used easily, they can be used up properly for reasons of hygiene such as when they are dirty. Therefore, it can be widely used in various places such as homes, factories, hospitals, hotels, laboratories, and restaurant kitchens. In particular, since the glove of the present invention has a slight adhesiveness on the outer surface, it has become possible to carry out fine work on the fingertips that was not possible when using conventional products. For example, in a laboratory, glass articles such as beakers and test tubes can be easily grasped and released. Therefore, in addition to detailed work in the laboratory, it is also used for places where safety and hygiene needs to be maintained, such as homes, hospitals, hotels, restaurant kitchens, and assembly of precision machine parts in factories, etc. Can be widely used.
