Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretchable glove, and more particularly to a stretchable glove having strength enough to be used repeatedly to some extent, particularly at a seam portion, and having an excellent fit and a feeling of wearing. .

[0002]

2. Description of the Related Art Conventionally, thermoplastic resins such as polyethylene are used as disposable gloves used for water work at home and disposable gloves for work in factories. As a method of making gloves using such a thermoplastic resin, a method of laminating two thermoplastic resin sheets and then heat-sealing the laminated sheet in a hand shape has been adopted. According to the method, the heat-sealed portions of the two sheets are welded and cut,
As a result, a hand-shaped glove in which the heat-sealed portion becomes a so-called seam is completed.

[0003] By the way, simple gloves used for such disposable applications are required to be supplied at a low cost. For this purpose, a mass production method is adopted, and as a result, the gloves are manufactured. The variety in glove size is also small, and it is inevitable that the size of the glove will be slightly larger than that of a typical adult hand. For this reason, there is a problem that it cannot always be said that it gives satisfactory usability to all people, and that it is not suitable for precise work because it does not fit snugly to the hand. That is, for example, when an elastomer film is used as the work glove, the glove is in close contact with the hand and has an excellent fit, but has a sticky feeling and a discomfort when worn.
In addition, knit gloves in which the surface is impregnated with a polyurethane resin are excellent in fit and wear, but the manufacturing process becomes complicated, resulting in an increase in cost. Furthermore, in the case of inexpensive manufacturing by the heat sealing method, the strength of the seal portion is weak because the seam is formed only by the heat seal, and the root portion of the finger portion, particularly the root portion of the thumb portion and the index finger portion is extremely simple. There was also a problem that it was torn. Under such circumstances, improvement has been demanded.

[0004]

In the present invention, the base of the finger, particularly the base of the thumb and the index finger, is hardly torn even under repeated use in such a situation, and the feeling of wearing is low. It also provides excellent stretchable gloves.

[0005]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that as a material, a thermoplastic resin having elasticity, and a thermoplastic resin having elasticity in addition to thermoplastic resin having elasticity. By using a porous substrate made of a non-woven fabric, preferably a laminated sheet, and the base portion between the thumb and the index finger having a corrugated shape, or by forming the thumb and the index finger It has been found that the above object can be achieved by setting the angle of the V-shape within a predetermined range. The present invention has been completed based on such findings. That is, the present invention provides (1) a glove obtained by laminating two material sheets made of a thermoplastic resin having elasticity and shaping the laminated sheet into a hand shape by heat sealing. A glove in which the base between the index finger portions has a wavy shape, (2) two material sheets made of a thermoplastic resin having elasticity are superimposed,
In a glove obtained by shaping the overlapped sheet into a hand shape by heat sealing, a glove formed by a thumb and a forefinger having a V-shaped angle of 60 ° to 90 °, (3) the material sheet includes: The glove according to the above (1) or (2), which is a laminated sheet in which a porous base material made of a thermoplastic resin having elasticity is laminated on a thermoplastic resin having elasticity, and (4) the thermoplastic resin having elasticity. It is an object of the present invention to provide the glove according to the above (3), wherein the porous base material is a nonwoven fabric.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below. 1. Sheet used as material (1) Thermoplastic resin having elasticity The type of the thermoplastic resin is not particularly limited.
A resin excellent in heat sealability is desirable because it is used for forming a glove by shaping into a hand shape by heat sealing. Further, a stretchable material having a good fit is preferable. Specific examples include linear low-density polyethylene (LLDPE), thermoplastic elastomer, and synthetic rubber-containing thermoplastic resin. As the thermoplastic elastomer, urethane type, olefin type, styrene type, ester type, amide type, vinyl chloride type and the like can be used.

[0007] As a sheet forming method, a known forming method such as inflation molding or T-die molding may be used as appropriate. The thickness of the sheet is preferably 20 to 200 μm, more preferably 40 to 100 μm. (2) A laminated sheet in which a porous base material made of a thermoplastic resin having elasticity is laminated on a thermoplastic resin having elasticity, as compared with a case where a single layer of thermoplastic resin having elasticity is used as a material. When a laminated sheet in which a porous base material made of a thermoplastic resin having elasticity is laminated is used, it is preferable because there is no sticky feeling when worn. In gloves,
In the laminated sheet, a porous base layer made of a thermoplastic resin having elasticity is made to be on the side in contact with the skin.

The thermoplastic resin having elasticity is the same as described above. Although there is no particular limitation on the porous substrate made of a thermoplastic resin having elasticity, a nonwoven fabric is preferably used. The nonwoven fabric includes not only a product nonwoven fabric that has undergone a bonding process such as thermal bonding or bonding with an adhesive, but also a so-called nonwoven web that has not undergone these bonding processes. Although there is no particular limitation on the fibers used, polypropylene, polyethylene, polyethylene terephthalate (PET), polyurethane, polyamide, cellulosic fibers, and composite fibers thereof are preferably used. Among them, polypropylene is more preferably used. The method for producing the nonwoven fabric is not particularly limited, and the nonwoven fabric can be produced by a known method such as spun bonding, spun lace, hot air card, hot embossed card, and melt blow. In addition, composite fibers of the spun bond method and the melt blow method, specifically, composite fibers such as spun bond method / melt blow method / spun bond method, and spun bond method /
Compounds such as a melt blow method can also be used. Further, it is also possible to use a composite short fiber (for example, polyethylene and polyethylene terephthalate) formed into a sheet using a card machine and heat-sealed with hot air or hot emboss.

The basis weight of the nonwoven fabric is not particularly limited, but is 10 to 30 g / m ² , preferably 15 to ²⁰ g / m ² .
² If it exceeds 30 g / m ² , the nonwoven fabric itself may be thick, and if it is less than 10 g / m ² ,
There is a problem that it is difficult to obtain industrially stable quality. There is no particular limitation on the laminated sheet. That is, the ratio of the thickness of the thermoplastic resin layer having elasticity to the thickness of the porous base layer made of the thermoplastic resin having elasticity and the overall thickness may be appropriately selected depending on the purpose of use. 2. Manufacturing Method The glove is manufactured by stacking two material sheets made of a thermoplastic resin having elasticity or the above-mentioned laminated sheet, and shaping the stacked sheet into a hand shape by heat sealing. That is, two sheets of the material are superimposed,
Then, the overlapped sheets are heat-sealed in a hand shape, so that the portion is welded and cut, whereby a hand-shaped glove in which the heat-sealed portion becomes a so-called seam can be manufactured. Heat sealing methods include hot plate sealing,
An ordinary method such as a high-frequency welder, an ultrasonic seal, or an impulse seal may be used. A method of punching into a hand shape at the same time as heat sealing, for example, a fusing and sealing method is preferred because the process is simple and the productivity is high. When the laminated sheet is used as a material sheet, if a film surface excellent in heat sealability is laminated and formed, and then turned upside down so that the film layer comes to the outside of the glove, even if the glove is repeatedly attached and detached, the fiber can be removed. Dropping, so-called lint, can be suppressed, and a porous substrate layer is provided on the inner side, so that a feeling of fitting and wearing is excellent. 3. Features of the form of the glove according to the present invention In the glove according to the present invention, the base portion between the thumb and the forefinger has a wavy shape, or a V-shape between the thumb and the forefinger. Angle of 60 to 90
° is required. By adopting such a configuration, since the seal portion does not extend completely, the strength is maintained even when the seal portion is repeatedly used, and the seal portion is not easily broken. The shape of the corrugation, the number of waves, and the like are not particularly limited, and may be appropriately selected depending on the purpose of use.
