JPH07138869A - Connection of a water-proof globe to an arm cover into a water-proof glove having the arm cover connected - Google Patents

Abstract

PURPOSE:To produce water-proof glove having the arm cover integrated with high strength by connecting the end opening of the main body of a water-proof globe having knitted fabric as the inner layer to the arm cover through the fusion of adhesive tape between them. CONSTITUTION:The main bodies of globe are prepared by impregnating knitted back cloths cut and sewed in globe shapes with acrylonitrile-butadiene rubber from the outer surface in such an extent that the rubber liquid fills the knit stitches but does not exude to the back surface and then heat-treating. Subsequently, an adhesion tape having an adhesive layer of polyvinyl acetate or a vinyl chloride/vinyl acetate copolymer on the basic layer of poly(vinyl chloride) film containing 40 to 100 PHR of plasticizer is tentatively applied to the opening end of the glove. Further, an arm cover made of poly(vinyl chloride) film or leather is inserted into the glove opening to overlap the arm cover end on the globe opening end and the overlapped part is fused with a high-frequency welder.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for connecting an arm cover of a waterproof glove with an arm cover and a glove body.

[0002]

2. Description of the Related Art There is one in which a glove body and an arm cover are made of the same thin synthetic resin material and are welded by a high frequency welder to obtain a waterproof glove with an arm cover.

[0003]

Although the conventional waterproof gloves with arm covers have a certain function in terms of waterproofing, they are weak in oil resistance, abrasion resistance or mechanical strength required for work. There are drawbacks.

In view of such a normal situation, the present invention was devised for the purpose of providing a product suitable for work.

[0005]

[Means for Solving the Problems] Between a hem mouth of a glove body having an inner surface made of a knitted fabric and an arm cover made of a polyvinyl chloride film or polyvinyl chloride leather inserted into and engaged with the hem mouth, a plastic 40 to 100 PHR of polyvinyl chloride film, polyvinyl acetate, or a copolymer resin of polyvinyl chloride and polyvinyl acetate, with a connecting tape having a thickness of 0.1 to 1.0 mm interposed therebetween. The connecting tape is melted with a high-frequency welder, etc. and the glove body and the arm cover are welded to obtain a waterproof glove with an arm cover.

The thickness of the connecting tape is optimally in the range of 0.2 to 1.0 mm. That is, if the thickness of the connecting tape is too thin, the stitching of the stitches becomes less and the adhesive force after bonding becomes weak. If it is too thick, proper adhesion cannot be achieved. In addition, the amount of protrusion of the adhesive portion increases, resulting in a decrease in commercial value and a cost increase.

When the amount of the plasticizer mixed in the connecting tape is too large, the connecting tape becomes too soft and unsuitable in strength. When the amount of the plasticizer is too small, the connecting tape becomes too hard. It is impossible to connect to the arm cover without cutting into the stitches of the lining cloth.

[0008]

First Embodiment A method for connecting an arm cover of a waterproof glove with an arm cover and a glove body according to the present invention will be described with reference to FIGS. 1 to 3. 1 is a partially cutaway perspective view of a waterproof glove with an arm cover, FIG. 2 is an enlarged sectional view of a connecting portion between a glove body and an arm cover, and FIG. 3 is a sectional view of a connecting tape.

In the figure, reference numeral 1 is a glove body, and the glove body 1 is a knitted lining cloth 2 on which the acrylonitrile butadiene rubber 3 is formed by dipping.

That is, the knitted lining cloth 2 which has been cut and sewn in advance is suspended in a glove-molding die, which is depped with an acrylonitrile-butadiene rubber liquid, and then heat-vulcanized to obtain the glove body 1. Is.

When the acrylonitrile butadiene rubber 3 is formed on the knitted lining fabric 2 by dipping, the acrylonitrile butadiene rubber penetrates into the inside of the knitted lining fabric 2 through the knitting stitches. It does not penetrate to the point of damaging.

Next, a 0.75 mm thick connecting tape 6 made of polyvinyl chloride and having a plasticizer amount of 70 to 80 PHR was temporarily attached to the inside of the wrist of the glove body 1 with a hot air welder or a high frequency welder, and an arm. The cover 4 is engaged, inserted, and welded by a high frequency welder.

When the connecting tape 6 is welded, it is welded and fixed to the knitted portion and the acrylonitrile-butadiene rubber through the knitted stitch, so that a very strong adhesive strength can be obtained.

The arm cover 4 is a polyvinyl chloride film,
Alternatively, it is made of polyvinyl chloride leather.

[0015]

Second Embodiment In the second embodiment, the connecting tape having a two-layer structure shown in FIG. 4 is used.

That is, the connecting tape 6 is composed of two layers of an adhesive layer 7 and a base material layer 8. The portion which constitutes one adhesive layer 7 is vinyl acetate or polyvinyl chloride copolymer resin, and the amount of plasticizer is The sheet shape is 70 to 80 PHR and the thickness is 0.50 mm.

The second base material layer 8 is made of polyvinyl chloride, has a plasticizer amount of 40 to 50 PHR, and has a thickness of 0.25 mm.

Both sheets are laminated by a laminator to obtain a connecting tape having a thickness of 0.75 mm.

A glove made of acrylonitrile butadiene rubber is provided on the knitted fabric back side 2 with the adhesive layer surface 7 of the connection tape.
Temporarily attach with a hot air type welder. An arm cover made of polyvinyl chloride is inserted and engaged with this and welded by a high-frequency welder or the like.

This adhesive layer is very meltable,
Since it is embedded in the knitted stitch portion 2 of the glove lining and is fixed to both acrylonitrile butadiene rubber, a stronger adhesive effect can be obtained.

Further, since the base material layer has an appropriate hardness, it is effective for enhancing physical properties such as adhesive strength and tensile strength after connection.

As described above, the two-layer structure is effective in complementing each other on both the adhesive surface and the strength surface.

[0023]

[Other Examples] Acrylonitrile butadiene rubber was used as the material of the glove surface in each example, but urethane resin may be used, and knitted cloth is used as the lining cloth of the glove. It is also possible to use knitted fabrics such as cotton, cotton, and natural fibers such as suf, and a wide range of gloves with arm covers can be provided by an appropriate combination according to the purpose of use.

A hot air welder or an iron may be used as the welding means using the adhesive tape.

[0025]

The effect of the invention is that the surface of the glove body is made of special rubber,
Moreover, welding the arm cover made of polyvinyl chloride film or polyvinyl chloride leather to the back cloth of the main body has problems in terms of technical strength and strength. By interposing a connecting tape between the arm cover and the arm cover and melting it, the melt permeates and solidifies and adheres to the back cloth stitch side of the glove body, and is welded and connected to the arm cover side. In terms of process, the cost can be reduced by reducing the work process, and it has become possible to provide a waterproof glove with an arm cover that is inexpensive, has a wide purpose and a wide range of use, and is completely waterproof.
