Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing gloves,
More specifically, the present invention relates to a glove that is easy to insert the hand into and has an excellent fit, and a method for manufacturing the same.

2. Description of the Related Art Conventionally, synthetic resin gloves that are made by fusing or cutting films or sheets are well known. However, most of these products are made significantly larger than the hand method because the base fabric does not stretch, and they do not fit the hand when worn, making it difficult to move the fingers, making them uncomfortable to wear, and having poor workability. It was hot.

In order to improve these drawbacks, it is also known that elastic synthetic resin films or sheets are fused and cut, but although these allow easy movement of the hands and fingers, they are not breathable and are uncomfortable to wear. Many of them have a flat structure that makes it difficult to insert your hand into them. The present inventors completed the present invention as a result of research to eliminate such conventional defects.

An object of the present invention is to provide a glove that is easy to insert the hand into, fits the hand well when worn, is flexible, allows easy movement of the fingers, and is comfortable to wear. Another object is to provide an inexpensive and mass-producible method of manufacturing such gloves.

In the method of the present invention, when manufacturing gloves by overlapping two sheet-like materials, fusing them in the shape of a glove, and fusing and cutting them, the sheet-like material constituting the back surface and the elastic sheet constituting the palm surface are combined. The method is characterized in that a stretchable sheet-like material is overlaid with a stretchable sheet-like material stretched by 10 to 70% in a direction perpendicular to the middle finger, and then fused and cut.

Examples of the sheet-like material constituting the upper surface to be applied to the present invention include films, nonwoven fabrics, knitted fabrics, etc. made of known styrene, olefin, vinyl chloride, 1,2 polybutadiene, urethane, polyester, and polyamide. However, it is important to select the material, shape, thickness, etc. appropriately depending on the intended use of the gloves.

For example, it is preferable to use a film for waterproof purposes, and for other purposes, it is preferable to use nonwoven fabrics or knitted fabrics from the viewpoint of breathability. Further, these sheet-like materials may or may not be stretchable, but it is more preferable to have stretchability in view of the fit when worn or the ease of finger movement.

As the sheet-like material constituting the palm surface applied to the present invention, known styrene elastomers, olefin elastomers, PVC elastomers, 1,
2. Stretchable sheets such as films, nonwoven fabrics, knitted fabrics, etc. made of polybutadiene elastomer, polyamide elastomer, urethane elastomer, polyester elastomer, polyamide elastomer, etc. are used, but the material and form may vary depending on the intended use of the gloves. It is important to appropriately select the thickness, etc.

For example, it is preferable to use a film for waterproofing or anti-slip purposes, and for dust-free purposes, it is preferable to use a film so that sweat from hands or grime does not ooze out. For other uses, it is preferable to use nonwoven fabrics or knitted fabrics due to their breathability. Regarding the performance of these sheet-like materials, it is preferable to have a breaking elongation of 300% or more and a 100% elongation recovery rate of 85% or more. Therefore, it is best to use urethane elastomer films, nonwoven fabrics, or knitted fabrics. suitable. The most important feature of the method of the present invention is that the sheet-like materials that make up the palm surface are stacked, fused, and cut by stretching 10 to 70% in the direction perpendicular to the middle finger. %
If it is less than 70%, the resulting glove will have a flat structure, making it difficult to insert the hand, and the elongation rate will be 70%.
If it exceeds %, it will be easy to insert your hand, but you will not be able to feel the fit when wearing it. It also becomes more likely to tear during fusion and fusing. The elongation rate must therefore be between 10 and 70%, preferably between 20 and 50%.

The gloves of the present invention may be manufactured using any device or method, but for example, two sheets stacked together under predetermined conditions may be manufactured using a high-frequency welder equipped with a glove-shaped mold. It is preferable to perform cutting by melting and joining by fusion at the same time, and then cut the insertion portion of the hand afterwards.

The gloves obtained as described above are shown in Figures 1 and 2.
As shown in the figure, it is composed of a palm surface 1 and a palm surface 2, and has a three-dimensional structure due to the elastic recovery performance of the sheet-like material forming the palm surface, making it very easy to insert the hand or fingers. It also has elasticity, so you won't feel any discomfort when wearing it, and it fits your hand very well.
Work efficiency increases.

Furthermore, by combining various materials, shapes, thicknesses, etc. of the back and palm surfaces, it is possible to manufacture gloves suitable for various uses. For example, for chemical experiments, driving cars, various sports such as golf and baseball,
Gloves for general work, general household use, or dust-free use can be easily obtained.

In addition, since high frequency welders etc. can be used,
Since it can be mass-produced at low cost, it can be manufactured extremely advantageously in terms of cost.

The present invention will be described below based on Examples, but the present invention is not limited to the Examples in any manner.

Example 1 Polyurethane elastic fiber nonwoven fabric obtained by melt blowing method (fabric weight 80 g/m ² , strength 1.2 Kg/cm, elongation
650%, 100% elongation recovery rate 92%, rigidity 40mm) One piece has no elongation, the other one has 50% in the direction perpendicular to the middle finger.
% elongated materials were stacked on top of each other, fused into the shape of a glove using a high-frequency welder, and then fused and cut. Then, the hand insertion part was cut to produce gloves. These gloves were extremely flexible and fit the hand well, causing little discomfort when worn, and were breathable, so sweat did not accumulate, making them very comfortable to wear. It was suitable for gloves for driving a car and for various sports.

Example 2 The polyurethane elastic fiber nonwoven fabric used in Example 1 was applied to the upper surface, and a polyurethane elastic film (thickness
200μ, strength 10Kg/cm, elongation 600%, 100% elongation recovery rate 87%) was stretched by 30% as the palm surface, two layers were stacked, and the gloves were made using a high-frequency welder as in Example 1. Created.

This glove had good flexibility, fit the hand well, and was extremely comfortable to wear. Since the palm surface is made of film, even if sweat or the like comes out due to long-term use, the sweat or the like will not transfer or adhere to the objects that are gripped, making them particularly useful as dust-free gloves.

Comparative Example 1 When a glove was manufactured using the palm surface elongation rate of Example 1 as 5%, it was difficult to insert the hand due to the planar structure. Furthermore, when a glove was made with the elongation rate of the palm surface of Example 2 being 100%, it was easy to insert the hand into the glove, but it did not fit the hand and was uncomfortable to wear.

On the other hand, I purchased commercially available polyethylene film gloves (approximately 200μ thick, no elongation, no elasticity), and when I tested them, I found that the base fabric had no elongation, so they were significantly larger than the size of my hands. It didn't fit my hand well, and although I wore it for a short time, it made me sweat and was very uncomfortable to wear.
