Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for work in which a flexible film such as a vinyl chloride resin film, a natural rubber film or a synthetic rubber film is formed on the outer surface of a seamless knitted glove that has been subjected to an antibacterial and deodorant treatment. The present invention relates to a glove and a manufacturing method thereof.

[0002]

2. Description of the Related Art Conventionally, vinyl chloride resin paste or natural rubber latex has been applied to the outer surface of gloves knitted with knitted fabric or knitted gloves to form a resin film or rubber film on the outer surface to improve durability. Work gloves considered as such are widely used.

[0003] As described above, a sewn glove made of a cloth knitting a thread or a knitted glove made by directly knitting a thread into a glove shape is coated with a coating material such as vinyl chloride resin paste or rubber latex on the surface thereof. When applying, setting the viscosity of this coating material to a low value makes it easier for the coating material to permeate into the fabric and stitches, penetrates to the inner surface of the knitted gloves, and causes strike-through, impairing the feel and feel of the inner surface. It is necessary to set the viscosity of the coating material used to be relatively high to suppress the penetration.

However, when the viscosity of the above coating material is increased, the coating film becomes thick and lacks in flexibility as a work glove, which has a problem that the workability of wearing the work glove is affected. There is.

In view of the above points, it is effective to form the coating film as thin as possible in order to increase the flexibility of these work gloves, but if the viscosity of the coating material is set low for that reason, as described above. The coating material will penetrate deeply into the fabric or stitches of the gloves,
It is necessary to strictly control the viscosity and coating conditions of the coating material, which is an obstacle to improving productivity.

On the other hand, as a means for solving the above-mentioned problems, the sewn gloves or knitted gloves are subjected to water-repellent or oil-repellent treatment to prevent penetration of the coating material to prevent strike-through, and to improve flexibility and texture. The technology is designed to improve. The water-repellent and oil-repellent treatment is performed by forming gloves by sewing or knitting and then impregnating the treatment agent.

[0007]

However, in the case where the water-repellent and oil-repellent treatments are performed in the post-process as described above, the manufacturing process is complicated, the manufacturing control is complicated, the production efficiency is lowered, and the cost is increased. Have a problem to do.

Regarding the water and oil repellency treatment, too much water and oil repellency can be imparted evenly because the coating material such as vinyl chloride resin paste or rubber latex does not uniformly adhere to the surface of the glove material. There is a possibility that coating cannot be performed and a coating having a predetermined thickness cannot be obtained, or pinholes are formed.

On the other hand, in the work gloves having the resin coating or the rubber coating on the surface as described above, the resin coating on the surface or the like causes poor breathability, and the inside of the glove may be worn when used.
Microbes (Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, etc.) proliferate due to adhered sweat, hand plaque, and the like, giving off a foul odor, and rarely causing skin rash.

Therefore, in view of the above problems, the present invention forms a flexible film without strike through when applying a coating material such as vinyl chloride resin paste or rubber latex on the outer surface of a knitted glove, and performs antibacterial and deodorant processing. It is an object of the present invention to provide a hygienic work gloves to be applied and a simple manufacturing method thereof.

[0011]

In order to solve the above-mentioned problems, the work gloves of the present invention are composed of treated yarns treated with an antibacterial deodorant and a water and oil repellent agent and untreated yarns in a separated state. <br/> the outer surface of the <br/> so knitting the knitted glove untreated yarn processing thread while mating observed inner surface is unevenly distributed on the outer surface, a vinyl chloride resin film,
It is formed by forming a flexible coating such as a natural rubber coating or a synthetic rubber coating.

Further, the method of manufacturing working gloves of the present invention comprises:
A processing yarn antibacterial agent and treated with a water repellent oil repellent, organized with combinations in a state in which divided the untreated yarn, provided the knitted gloves processing thread is unevenly distributed in the untreated yarn outer surface to the inner surface, knitted gloves Coating material such as vinyl chloride resin paste, natural rubber latex, synthetic rubber latex, etc. on the outer surface of
After coating with no liquid pressure or low liquid pressure by drop coating, spray coating, inclined dip coating, etc., heat treatment is performed to melt and completely gel or vulcanize the above coating film, and then cooling, It is characterized in that a flexible film such as a vinyl chloride resin film, a natural rubber film, a synthetic rubber film or the like is formed on the surface.

The treated yarn and the untreated yarn are fiber yarns produced or bleached from natural fibers or synthetic fibers. The treated yarns are water-repellent or oil-repellent treated by impregnating the fiber yarns with a water- and oil-repellent agent. Simultaneously with the application, it is impregnated with an antibacterial deodorant and subjected to an antibacterial deodorant treatment. As the water- and oil-repellent agent, for example, a fluorine resin having oil repellency with respect to a plasticizer of vinyl chloride resin paste and water repellency with respect to water of natural rubber latex or synthetic rubber latex is used as an antibacterial deodorant. Organosilicone quaternary ammonium salt or the like is used.

[0014]

In the working glove according to the present invention as described above, the outer surface of the knitted glove in which the treated yarn treated with the water and oil repellent agent is knitted is coated with the soft coat, so that the treated yarn is coated with the treated yarn. Penetration into the mesh is suppressed and the surface part is impregnated and adheres without strike-through, and the coating is thin and flexible, improving workability when wearing gloves,
Since the treated yarn with antibacterial and deodorant treatment is located only on the inner surface of the knitted gloves that come into contact with the hands, the effective antibacterial and deodorant effect suppresses the growth of bacteria and prevents the generation of foul odors, etc. Is.

Further, in the method of manufacturing a working glove according to the present invention, the treated yarn is treated by coating the outer surface of the knitted glove in which the treated yarn treated with the water and oil repellent agent is knitted on the inner surface with the coating material. As a result, the penetration of the coating material into the mesh is suppressed, and the coating material penetrates into the untreated yarn on the surface without holding through and is retained in the knitted glove. In addition, the viscosity of the coating material can be set to a low level by being adhered and suppressing the above-mentioned penetration. As a result, working gloves with a high flexibility can be obtained by forming a thin film, and the usable viscosity of the coating material can be obtained. The area is comparatively wide, the flow characteristics do not need to be strictly controlled, the manufacturing control technology is simplified, and the manufacturing cost can be reduced with the increase in production efficiency.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a work glove according to an embodiment of the present invention by partially removing it, and FIG. 2 is a sectional view thereof.

The work glove 1 is composed of a flexible coating 2 on the outer surface and a knitted glove 3 on the inner surface. The flexible coating 2 is
The flexible coating 2 is formed of a vinyl chloride resin coating, a natural rubber coating, a synthetic rubber coating or the like, and the inner surface side of the flexible coating 2 penetrates into the mesh and fibers on the outer surface side of the knitted glove 3 and is integrally joined.

As shown in a partially enlarged view of FIG. 3, the knitted glove 3 is knitted into a glove shape by a known glove knitting machine or the like by the combination yarn 6, and the combination yarn 6 is As shown further enlarged in FIG. 4, one treated yarn 5 and two
It is composed of untreated yarns 4 and 4 and is knitted so that the treated yarn 5 is located on the inner surface side.

The treated yarn 5 is made of natural fiber or synthetic fiber and is subjected to water and oil repellent treatment and antibacterial and deodorant treatment, and the untreated yarn 4 is water and oil repellent and antibacterial and deodorant treated. It is a plain yarn (produced or bleached) made of natural fibers or synthetic fibers that have not been treated.

Specifically, the treatment of the treated yarn 5 is as follows:
Using a corn rewinder, set cheese with a single cotton thread and set it to a roll density of 0.3 and rewind it into corn. Next, the rewound corn is set in a cheese dyeing machine, and the treatment liquid is put in this dyeing machine and circulated by a pump. This treatment liquid is an aqueous solution of a fluororesin emulsion having water and oil repellency, an organosilicone quaternary ammonium salt which is an antibacterial deodorant, and a leveling agent. For example, the amount of the treatment liquid added is 15 times the yarn weight, the treatment liquid temperature is raised to 40 ° C., and the treatment liquid circulation pressure is about 7 kg / cm ² so that the treatment liquid circulates from the inside to the outside of the cone. Adjust to. Further, a reversing operation for reversing the flow of the treatment liquid from the outside to the inside is performed every 5 minutes, and this is repeated 3 times to impregnate the yarn with the treatment liquid. After that, the cone is taken out and set in the blow pressure dryer, and the vapor pressure in the dryer is 4.0 to 4.5.
Dry for 30 minutes under the conditions of kg / cm ² and temperature of 110 ° C. After drying, the yarn is rewound from the cone on the wood tube and treated yarn 5
Is what you get.

At the time of knitting the knitted glove 3 by the knitting machine, a thread aligner 7 as shown in FIGS.
One of the 30 single-thread treated yarns 5 is passed through the inner yarn path 8 of the thread aligner 7, and similarly, the 30 single-thread untreated yarns 4, 4 are passed through the outer yarn passage 9 and the treated yarns are processed. 5 and the untreated yarns 4 and 4 are supplied in combination, and the knitted glove 3 is knitted by the knitting machine in a state in which the treated yarn 5 is unevenly distributed so that the combined yarn 6 is always located inside. In the knitted glove 3 knitted using the thread aligner 7, the treated yarn 5 appears only on the inner surface or the outer surface of the knitted fabric corresponding to the installation direction of the thread aligner 7, and the opposite surface is untreated. It is constituted by the yarns 4 and 4. The knitted glove 3 is used such that the treated yarn 5 is located on the inner surface, and when the treated yarn 5 is knitted on the outer surface side, it is turned inside out and used.

Subsequently, the knitted glove 3 is mounted on a metal (aluminum) hand mold, and the flexible coating 2 is applied and formed on the outer surface thereof. The manufacturing process of the flexible coating 2 differs between a case of vinyl chloride resin or other synthetic resin and a case of natural rubber or synthetic rubber, which will be described separately below.

To form the flexible coating 2 of vinyl chloride resin, first, prepare a vinyl chloride resin paste having a viscosity adjusted to about 3000 cp, and apply it to necessary parts such as the palm, back, and fingers of the knitted glove 3. The vinyl chloride resin paste is coated on the outer surface by dropping so as not to apply liquid pressure, and the excess applied resin paste is removed by natural dropping.

When the coating material is coated with the plasticizer-dispersed vinyl chloride resin paste as described above, the untreated yarn 4 faces the outer surface of the knitted glove 3 and the water- and oil-repellent treatment is applied to the inner surface. When the treated yarn 5 having been subjected to the treatment faces, the applied vinyl chloride resin paste permeates into the portion of the untreated yarn 4 on the outer surface side, but the treated yarn 5 on the inner surface side has the strength of the oil-repellent property. Therefore, penetration is prevented and strike-through does not occur, and the inner surface portion of the knitted glove 3 is left in the texture of the fiber yarn.

Then, the coated knitted gloves are placed in a hot air circulation oven having an ambient temperature of 180 ° C., and the applied vinyl chloride resin paste is melted and completely gelated by heating for 15 minutes. By removing from the mold, the flexible coating film 2 made of vinyl chloride resin is applied to the outer surface of the knitted glove 3 whose inner surface is treated with the antibacterial and deodorant treated yarn 5.
It is intended to produce hygienic work gloves 1 having a good texture, which is excellent in flexibility and is coated with.

Next, in forming the flexible coating 2 of natural rubber, first, a natural rubber latex having a viscosity adjusted to about 400 cp is prepared, and the palm portion of the knitted glove 3 attached to the hand mold,
This natural rubber latex is coated on the outer surface of the necessary parts such as the back of the hand and fingers by dropping coating so as not to apply liquid pressure, and then placed in a warm air circulation oven with an ambient temperature of 90 ° C and dried for 10 minutes. Then, it is immersed in a natural rubber latex having a viscosity adjusted to 50 cp at an inclination angle of 35 °, and a second coating is performed by inclined dip coating so that the liquid pressure is applied only slightly.

Even when the coating material of the water-dispersed natural rubber latex as described above is applied, the untreated yarn 4 faces the outer surface side of the knitted glove 3 and the water- and oil-repellent treatment is applied to the inner surface side thereof. When the treated treated yarn 5 faces, the applied natural rubber latex permeates into the untreated yarn 4 on the outer surface side, but the permeation of the treated treated yarn 5 on the inner surface side is prevented due to its water repellency. As a result, the inner surface of the knitted glove 3 is left in the texture of the fiber yarn without causing strike-through.

This was placed in a warm air circulation oven with an ambient temperature of 100 ° C. and dried for 10 minutes, and then placed in a warm air circulation oven with an ambient temperature of 125 ° C. and heated for 15 minutes to carry out the primary vulcanization. Then cool and remove from the hand mold. Then, the secondary treatment was performed for both secondary vulcanization and drying. The treated yarn was placed in a warm air circulation oven with an ambient temperature of 120 ° C., heated for 7 minutes, taken out and cooled, so that the inner surface was treated with an antibacterial and deodorant treatment. The knitted glove 3 is manufactured by covering the outer surface of the knitted glove 3 with a soft coating film 2 made of natural rubber to produce a hygienic work glove 1 having a high degree of flexibility and a good texture.

On the other hand, in the case of forming a synthetic rubber film of synthetic rubber latex, basically, it may be carried out in the same manner as the coating with the above-mentioned natural rubber, but the coating material is selected according to the material of the synthetic rubber latex. Processing conditions such as viscosity, drying temperature and vulcanization temperature are different.

As the water and oil repellent, an organic solvent dispersion or aqueous suspension of trifluorochloroethylene resin, tetrafluoroethylene resin, fluorinated polyacrylic resin, perfluoroalkoxyethylene or the like can be used. In particular, a coagulant can be used as a water repellent agent for the treated yarn for natural rubber latex. Further, the organosilicone quaternary ammonium salt as the antibacterial deodorant is a non-eluting type drug, and its component is reactively immobilized on the cellulosic fibers and does not elute with sweat and exerts a dedicated defense type antibacterial property. Although sufficient effectiveness can be obtained with one treated yarn on the side that is touched by the hand, other known antibacterial and deodorant agents may be used.

In the above embodiment, the knitted glove is knitted by combining 1 treated yarn and 2 untreated yarns. However, 2 treated yarns and 1 untreated yarn, 2 treated yarns and 2 untreated yarns are knitted. It is also possible to appropriately change the combination of two threads or the like, and by changing this combination, the degree of penetration of the coating film changes and the flexibility can be set appropriately. The same effect can be obtained by changing the treatment concentration of the water / oil repellent agent.
