Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a multifunctional glove and a method for manufacturing the same.

[Prior art and its problems]

Nowadays, the content of various tasks has become complex, and the function of gloves has changed from a single function of simply protecting the hands.
In order to be able to work efficiently, products are now required to have multiple functions such as wear resistance, cut resistance, and anti-slip properties. For example, gloves made of cloth having a flexible resin coating formed on their surfaces are required to simultaneously satisfy the anti-slip function and the abrasion resistance of cloth gloves. In this case, if the anti-slip function is improved, the coating becomes more likely to wear out. However, if the abrasion resistance of the coating is improved, the anti-slip effect cannot be expected much, and it is thought that the anti-slip function and the abrasion resistance are contradictory. However, consumers are demanding gloves that satisfy both of these properties at the same time.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a multi-functional glove that simultaneously satisfies wear resistance, strong cut resistance, anti-slip function, etc., and a method for manufacturing the same.

[Means to solve the problem]

The technical means of the present invention taken to achieve the above object are as follows. In the invention of the multifunctional means, the glove comprises a permeable cloth glove; a resin liquid is directly dotted on the surface of the cloth glove, and then the resin liquid solidifies. a flexible resin coating formed on the surface of the cloth glove excluding at least the portion where the hard resin projections are formed; A portion of the resin forming the protrusions penetrates the cloth glove and solidifies to form a root, and the flexible resin coating is formed when the resin liquid adhering to the cloth glove is in a sol state. Countless recesses formed by the bursting of countless small bubbles in this resin liquid; and irregular net-like non-slip protrusions formed relative to each other by the formation of these countless recesses; , and the countless recesses include
This is a multi-functional glove that includes both transparent and non-permeable gloves. Cloth gloves are made of woven or knitted fabrics and are permeable. The materials include cloth, synthetic fibers,
You can give cotton etc. The number, shape, and position of the hard resin protrusions formed by directly adhering to the surface of the cloth glove are appropriately set depending on the nature of the work. For example, when performing work that requires easy bending of the fingers, the hard resin protrusions are arranged so as not to hinder the bending of the fingers. Examples of means for providing a flexible resin coating on a cloth glove include a method of dipping the glove in a resin liquid, a method of applying or spraying the resin liquid, and the like. The flexible resin coating can be provided over the entire surface of the cloth glove except for the areas where the hard resin protrusions are formed, or it can be provided only on a part of the surface of the cloth glove, for example, only on the palm. You can also do it. Natural resins such as natural rubber, synthetic resins such as vinyl chloride resins, vinyl acetate resins, polyurethane resins, and synthetic rubbers are used as resins for the hard resin protrusions and flexible resin coatings. The recesses provided on the surface of the flexible resin coating have, for example, a crater shape, and the size and depth as well as the shape can vary depending on the size of the bubbles and their density, as will be explained in later examples. Not constant. Some of these recesses have permeability and can allow gas or liquid to pass therethrough, while others do not have permeability, and these recesses are mixed. In other words, cloth gloves in which the flexible resin coating is not cross-linked between adjacent yarns and the gaps between the yarns are through-holes, and those in which the flexible resin coating is cross-linked,
If the coating is destroyed, it is permeable. However, cloth gloves whose surfaces are completely covered with a flexible resin coating are not permeable. The anti-slip protrusion is formed relative to the shape of the concave portion due to the bursting of the bubble, and is irregularly formed depending on the size of the bubble and its density. Examples of its shape include leaf veins, luffa fibers, irregular bee-like shapes, and capillary shapes distributed throughout the tissue. In the invention of a method for manufacturing multi-functional gloves, the invention provides a method for manufacturing gloves in which a resin liquid is attached to the surface of a cloth glove, and then heated to gel to form a film on the surface of the cloth glove, the method comprising: Step of dotting and adhering the resin liquid directly to the surface and then solidifying the resin liquid to form a large number of hard resin protrusions; attaching the resin liquid containing countless small bubbles to the glove obtained in the above step. Step: By bursting the small bubbles in the resin adhering to the glove obtained in the above step, numerous recesses and depressions are formed on the surface of the cloth glove except for the areas where the hard resin protrusions are formed. , forming a flexible resin coating having irregular mesh-like anti-slip protrusions relatively formed by the formation of the recesses;

【Example】

The present invention will be explained in more detail with reference to embodiments shown in the drawings. Figure 1 is a plan view with the palm side facing upward, and Figure 2 is a cut end surface taken along line X-X in Figure 1. FIG. 3 is an enlarged view of part A in FIG. 1, and is an explanatory diagram showing the state in which a flexible resin coating is formed on the surface of a cloth glove. , FIG. 4 is a schematic explanatory view showing the -cut end surface of FIG. 3. In the figure, reference numeral 1 indicates a cloth glove.
The cloth glove 1 is made of knitted cotton yarn and has breathability and permeability. On the palm surface of the cloth glove 1, a large number of hard resin protrusions 2 are formed by directly applying a resin liquid dotted thereon and solidifying the resin liquid.
...is provided. In this embodiment, the hard resin protrusion 2
... are arranged in the shape of cut stones with some distance between them, but the arrangement is not limited to the above arrangement, and can be arranged in a state suitable for various work purposes. The hard resin protrusion 2... is formed at the location where it is formed.
A portion of the resin forming the hard resin protrusions 2 penetrates into the cloth glove 1 when in liquid form, forming a root portion 21 that looks like the root of a plant (see FIG. 2). A flexible resin coating 30 is formed on the surface of the cloth glove 1 except for the areas where the hard resin protrusions 2 are formed. The flexible resin coating 30 is formed when the resin liquid attached to the cloth glove 1 is in a sol state.
Innumerable recesses 5, 6 formed by the bursting of countless air bubbles in the resin, and a highly protruding irregular network formed relative to each other by the formation of the countless recesses 5, 6. It has anti-slip protrusions 3 on its surface. The recesses 5 and 6 are not uniform in size, and there are recesses 5 whose bottoms reach or near the surface of the cloth glove 1 and recesses 6 whose bottoms do not reach the surface. Even among the recesses 5 whose bottoms reach the surface or the vicinity of the surface of the cloth glove 1, some have the penetration holes 20 and some do not. The anti-slip protrusion 3 has elasticity, gradually becomes sharper toward the tip, and its height is not uniform. Here, the process of forming the recesses 5 and 6 and the anti-slip protrusion 3 will be explained with reference to FIG. The cloth glove 1 is immersed in a foamed resin liquid (latex, plastisol, organosol, etc.) in which numerous air bubbles 7 and 8 of various sizes with a particle size of about 0.2 to 2.0 mm are mixed, and the air bubbles 7 are formed on the surface of the cloth glove 1. ,8
(See Figure 5a). The cloth glove 1 is lifted out of the resin liquid, and the bubbles are sequentially ruptured in a sol state. At this time, when the bubbles 8 having a large particle size burst, a crater-shaped recess 5 that reaches the surface or the vicinity of the surface of the cloth glove 1 is formed at the location where the bubble 8 bursts. When the bubble 7 with a small particle size bursts, the burst part forms a crater-shaped recess 6 that does not reach the surface or near the surface of the cloth glove 1 (Fig. 5c).
reference). In addition, since the bubbles are burst one after another while the resin liquid is in the sol state, the anti-slip protrusion 3 formed by the cohesive force of the burst liquid phase is wide at the point where it rises from the cloth glove 1, and As the shape increases, the width becomes narrower and becomes sharper (Fig. 5b, Fig. 5c)
reference). Although the mechanism by which the above-mentioned anti-slip protrusion 3 is formed is not necessarily clear, it is thought to be as follows. That is, a portion of the liquid phase (diluent, plasticizer, etc.) containing the diluent of the resin liquid permeates into the cloth glove 1, making it more likely to burst, resulting in an increase in viscosity and yield value. The resin liquid whose viscosity and yield value have increased after the bursting of the bubbles forms a continuous protrusion along the contour of the bubbles due to cohesive force. Furthermore, it is thought that the diluent and the like are vaporized and released by heating, and are then heat-treated in a contracted state. In this way, the resin liquid after the bubbles burst has a higher viscosity in equilibrium with the decrease in the liquid phase, and at the same time, the yield value also increases and the fluidity becomes poor, so that the anti-slip protrusion 3 becomes difficult to collapse. It becomes sharp. In order to burst the bubbles, the viscosity of the resin liquid should be 500 CP or less, preferably 300 CP or less, which is easy to burst. To break the bubbles, put the gloves under reduced pressure, apply wind pressure of 4 m/sec or more, or 100℃~
Examples include a method of rapidly heating the gloves at 200°C to expand and break the bubbles, and a method of applying vibration or impact to the gloves. FIG. 6 is an end view of essential parts showing another embodiment of the glove according to the present invention. In order to increase the protrusion of the anti-slip projections 3, an appropriate amount of coarse resin or other coarse particles 4 is added to the resin liquid to an extent that does not cause sudden sedimentation when the resin liquid is in a foamed state. When the resin liquid containing the coarse particles 4 is attached to the cloth glove 1, the adsorption force and cohesive force of the resin liquid on the scattered coarse particles 4 work simultaneously, and the synergistic effect causes the protrusions to become high and sharply slippery. A stop protrusion 3 can be formed. It should be noted that the same or equivalent parts as in the above embodiment are indicated by the same reference numerals. Next, an embodiment of the glove manufacturing method according to the present invention will be described with reference to FIGS. 7 to 9. FIG. 7 is a plan view showing a state in which hard resin protrusions are formed on the palm surface of a cloth glove, and FIG.
It is a partially enlarged schematic view showing the cut end surface at point Y, showing a state in which hard resin protrusions are formed on the surface of the cloth glove. A method for manufacturing a glove according to the present invention includes: forming a hard resin protrusion on the palm surface of a cloth glove. A process of forming a resin coating on cloth gloves with hard resin protrusions. It can be roughly divided into two types. (1) A process of forming hard resin protrusions on the palm surface of cloth gloves.

After that, when the protruding template is removed, Figures 7 and 8 are shown.
The resin liquid remains scattered and arranged in a masonry pattern as shown in the figure. Thereafter, a hard resin protrusion 2 is formed on the palm surface of the cloth glove 1 which has been heated and gelled.

Immerse it in the resin liquid foamed by the machine. After the resin liquid has sufficiently adhered to the cloth glove 1, it is lifted out of the resin liquid and placed in a sealed vacuum container, and the pressure is reduced to 400 mm/Hg using a vacuum pump to burst the bubbles. It is then heated at about 185° C. for about 20 minutes to obtain the gloves shown in FIGS. 1 and 2.

【Effect of the invention】

The present invention has the above configuration and has the following effects. (1) The glove according to the present invention has a large number of hard resin protrusions formed by directly applying a resin liquid to the surface of a permeable cloth glove and then solidifying the resin liquid;
a flexible resin coating formed on the surface of the cloth glove excluding at least the portion where the hard resin protrusions are formed; To,
Countless recesses formed by the bursting of countless small bubbles in this resin liquid; and irregular net-like non-slip protrusions formed relative to each other by the formation of these countless recesses; has. For this reason, the hard resin protrusions provide wear resistance,
This is a multi-functional glove that not only has cut resistance, but also has an anti-slip effect due to its flexible resin coating, allowing one type of glove to be used for multiple types of work, compared to gloves that only have individual functions. Can be provided. (2) The hard resin protrusions are formed directly on the cloth glove, and a portion of the resin forming the hard resin protrusions penetrates the cloth glove and solidifies to form a root. For this reason, the gloves have superior strength compared to gloves in which hard resin protrusions are adhered to the coating, and the hard resin protrusions are difficult to remove from cloth gloves even when used for strenuous work. (3) On the surface of the flexible resin coating, there is a highly protruding irregular network of slips formed by the bursting of numerous bubbles in the resin liquid when it is in a sol state. A stop protrusion is provided. Therefore, the anti-slip protrusion has no directionality and can perform the anti-slip function against external forces from any direction. (4) Cloth gloves are permeable, and the countless recesses provided in the flexible resin coating include both permeable and non-permeable recesses. Furthermore, the anti-slip protrusions are formed by the bursting of bubbles when the resin liquid is in a sol state. Therefore, even if the object to be handled is wet with water, oil, etc., the anti-slip projections can break through the film of water, oil, etc. The water, oil, etc. that are removed at this time can pass through the recessed portions of the flexible resin coating and escape to the cloth glove side. Therefore, there is no film of water or oil between the flexible resin coating and the object to be handled, and the anti-slip protrusion can directly adhere to the object to be handled, and there is no slippage due to the film of water, oil, etc. It can perform the function of stopping. (5) Among the recesses provided in the flexible resin coating, the recesses that are not permeable have a suction cup shape.
By bringing it into close contact with the object to be handled, it can be expected to interact with the anti-slip protrusions to provide a sufficient anti-slip effect. (6) The flexible resin film has numerous recesses formed by bursting of bubbles. Therefore, the resin portion is reduced by the amount of the recessed portion, and the recessed portion serves as a resin release portion during bending. The glove is therefore extremely flexible and has no resistance to bending. (7) The flexible resin coating has permeable recesses. Therefore, they do not get stuffy even when worn, making them suitable as work gloves. (8) Cloth gloves are made of permeable materials. For this reason, part of the liquid phase containing the diluent of the resin liquid penetrates into the cloth gloves, and the resin liquid phase decreases, making it easier to burst.The viscosity of the resin liquid increases after bursting, and the resin liquid Due to the cohesive force of the foam, it is possible to form a thick non-slip protrusion that is raised high along the contour of the foam. Also, since the base is thick, it has sufficient strength against wear.
