Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for manufacturing work gloves, and more particularly, to a method for manufacturing work gloves used for electric work and the like.

[0002]

2. Description of the Related Art The following is a conventional method of manufacturing working gloves. That is, a cloth glove of knitted cloth is attached to a hand mold, the cloth glove is dipped in rubber latex or liquid synthetic resin, pulled up, and then dried to form a rubber or synthetic resin film on the outer surface of the cloth glove. Manufactures working gloves.

Another conventional technique for manufacturing working gloves is disclosed in Japanese Patent Application Laid-Open No. Hei 5-239775. That is, the dispersion liquid in which the superabsorbent resin in a water-absorbing state is dispersed in alcohol is moistened to the cloth gloves of the knitted fabric before or after being attached to the hand mold. After the cloth glove is dried, the cloth glove is immersed in a liquid synthetic resin dissolved in a hydrophilic solvent and heated to form a synthetic resin base layer on the outer surface of the cloth glove. Further, the cloth glove on which the base layer is formed is immersed in a liquid synthetic resin, heated to form a surface layer of the synthetic resin on the outer surface of the base layer, cooled, and then demolded.

[0004]

However, in the conventional technique, rubber latex or a liquid synthetic resin penetrates and impregnates the entire cloth glove, and in this state, the rubber or the synthetic resin is solidified. Is stuck to the solidified rubber or synthetic resin, and the stitches of the entire cloth glove are restrained by the rubber or synthetic resin. , The cloth gloves and the coating cannot move relative to each other. As described above, the flexibility is low, the work glove cannot smoothly follow the movement of the finger and can not be bent, and the work glove reduces the degree of freedom of movement of the finger, and the workability decreases. is there. In order to solve this problem, the cloth gloves may not be restrained by rubber or synthetic resin.In this case, the workability is improved, but the rubber or synthetic resin is not fixed to the cloth gloves. As a result, the thickness of the rubber or the synthetic resin is reduced, and the mechanical strength and the electrical insulation are reduced.

[0005] In another conventional technique, since the liquid synthetic resin hardly penetrates into the cloth gloves due to the high water-absorbing resin in the whole cloth gloves, the working gloves have flexibility. There is a problem that the thickness of the synthetic resin is reduced by the extent that it is not performed, and the mechanical strength and the electrical insulation are reduced. In order to solve this problem, the mechanical strength and the electrical insulation can be improved by increasing the thickness of the film consisting of the base layer and the surface layer of the working glove. There is a problem that flexibility is reduced and workability is deteriorated.

Therefore, there is a need for a working glove which solves the problems of the above two prior arts and achieves a predetermined mechanical strength and electrical insulation without lowering the workability.

An object of the present invention is to provide a method for producing a working glove which is flexible and has excellent mechanical strength and electrical insulation.

According to the first aspect of the present invention, a rubber latex or a liquid synthetic resin penetrates into a predetermined region on the outer surface of a stretchable porous cloth glove mounted on a hand mold. An operation, characterized by forming a coating made of rubber or synthetic resin on the outer surface of the cloth glove by subjecting the cloth glove, which has been subjected to the prevention treatment, to the cloth glove subjected to the permeation prevention treatment, by immersing the cloth in rubber latex or liquid synthetic resin. This is a method of manufacturing gloves.

According to the present invention, a predetermined region on the outer surface of a stretchable porous cloth glove mounted on a hand mold is subjected to a penetration preventing treatment of rubber latex or a liquid synthetic resin, and the penetration preventing treatment is performed. The cloth glove thus obtained is dipped in rubber latex or liquid synthetic resin to form the coating on the cloth glove, so that the cloth glove is impregnated with the rubber latex or liquid synthetic resin and solidified and not impregnated. Can be selectively provided. Therefore, in a region where the rubber latex or the liquid synthetic resin does not impregnate the cloth glove, the cloth glove and the coating are not adhered to each other. The coating can be moved separately from the coating, and the cloth glove and the coating can be offset from each other, increasing the flexibility in this area and thus the overall working glove. Further, rubber latex or liquid synthetic resin is impregnated into the cloth glove and solidifies in the remaining area of the cloth glove except for the area where the permeation prevention treatment has been performed. Strength is improved. By selecting the remaining area as an area that is likely to be in contact with a tool or the like during work and is susceptible to external actions such as scratching and piercing, a reduction in mechanical strength of the area is prevented, and the external action is prevented. Can be hardly damaged. Further, since a coating made of rubber and a synthetic resin is formed on the outer surface of the cloth glove, the work glove can be provided with electrical insulation. The remaining region has a large thickness of rubber or synthetic resin, and high electrical insulation can be obtained. As described above, the work gloves are provided with flexibility to improve workability, and can provide excellent mechanical strength and electrical insulation required for work.

According to a second aspect of the present invention, in the configuration of the first aspect, the predetermined area where the rubber latex or the liquid synthetic resin is subjected to the penetration preventing treatment is selected at least as an area covering the back of the hand. It is characterized by.

According to the present invention, the predetermined area to be subjected to the anti-penetration treatment is selected at least as an area covering the back of the hand, and rubber latex or a liquid synthetic resin does not impregnate at least the area covering the back of the hand, and the remaining area does not impregnate. Is impregnated with rubber latex or a liquid synthetic resin and solidified. Therefore, even if the user holds the hand while wearing work gloves, the cloth gloves and the coating on the back of the hand can move individually in a region where the cloth gloves and the coating come into contact with each other, and the elongation of the coating increases. Since the light does not directly reach the surface of the hand through the cloth glove, the work glove can smoothly follow the movement of the finger and bend the finger. In this way, the flexibility of the working glove is obtained, the degree of freedom of movement of the fingers when the working glove is worn is improved, and the hand is easily gripped with the working glove worn, thereby improving workability. be able to.

According to a third aspect of the present invention, in the constitution of the first or second aspect, the treatment for preventing penetration of rubber latex or liquid synthetic resin is performed by closing a gap on the outer surface of the cloth glove with a substance. It is characterized by being achieved by.

According to the present invention, in the construction of the first aspect of the present invention, the anti-penetration treatment is performed in a predetermined region on the outer surface of the cloth glove, for example, between the fibers forming the cloth glove and the cloth glove. It is achieved by closing the voids of the stitches with a substance, for example air bubbles, solidified rubber or synthetic resin, particulate matter, or a masking agent,
It is possible to prevent the rubber latex or the liquid synthetic resin from entering the gap, thereby preventing the region of the cloth glove from being impregnated with the rubber latex or the liquid synthetic resin. Therefore, it is possible to selectively provide a region where the rubber latex or the liquid synthetic resin is impregnated and solidified, and a remaining region where the rubber latex or the liquid synthetic resin is not impregnated. In addition, since the voids are closed with a substance, and the cloth glove is immersed in rubber latex or liquid synthetic resin to form the coating, a region where the rubber latex or liquid synthetic resin is impregnated and solidified and a region where no impregnation is performed are included. Can be easily manufactured, and productivity can be improved.

According to a second aspect of the present invention,
Since the anti-penetration treatment is achieved by closing the gap at least in the region covering the back of the hand on the outer surface of the cloth glove with a substance, the rubber latex or liquid synthetic resin is formed in the gap at least in the region covering the back of the cloth glove. Can be prevented from entering, and thereby, the region of the cloth glove on which the above-described permeation prevention treatment has been performed can be prevented from being solidified by impregnation of rubber latex or a liquid synthetic resin. Further, by closing the voids in the region with a substance and immersing the cloth glove in rubber latex or liquid synthetic resin to form the coating, a region in which rubber latex or liquid synthetic resin is impregnated and solidified, Working gloves that selectively provide at least a region that is not impregnated with rubber latex or liquid synthetic resin that covers the back of the hand can be easily manufactured, and productivity can be improved.

FIG. 1 is a plan view of a work glove 1 realized by a method for manufacturing a work glove according to an embodiment of the present invention, and FIG. 2 is a side view of the work glove 1. FIG. 3 is a sectional view taken along the line III-III in FIG. 1 to 3 show a state in which the work glove 1 is worn on a hand. The work glove 1 includes a cloth glove 2 and a coating 3 covering the outer surface of the cloth glove 2. The cloth glove 2 has elasticity and is porous, and is made of, for example, a knitted knitted fabric. The coating 3 is made of an electrically insulating rubber or a synthetic resin, and is made of, for example, natural rubber (hereinafter, may be simply abbreviated as rubber). The thickness of the coating 3 depends on the withstand voltage of the working glove to be manufactured according to JIS T 8112.
Is appropriately selected from 0.5 to 2.7 mm as specified in the above. For example, in the work glove 1 suitably used for work of 300 to 600 V AC, the thickness of the coating 3 is 0.5 to 1.
It is selected to be about 3 mm.

In a region on the outer surface of the cloth glove 2 which covers the back of the hand, a permeation prevention treatment region 4 which has been subjected to a rubber latex permeation prevention treatment is formed. That is, the permeation prevention processing area 4
Is not impregnated with the rubber latex, and the remaining region excluding the permeation prevention treatment region 4 is impregnated with the rubber latex and solidified. Therefore, the expansion and contraction of the cloth glove 2 is restricted by the rubber in the remaining area, but the penetration preventing processing area 4
In the above, since the rubber only contacts the outer surface of the cloth glove 2, the cloth glove 2 is not restrained by the rubber. Here, the region covering the back of the hand is a region covering from the wrist to the base of each finger and excluding the region on the palm side.

FIG. 4 is a sectional view showing a state where the work glove 1 is worn on the hand and the hand is held. When the user wears the work glove 1 and holds his hand, the back side of the work glove 1 extends,
The palm side shrinks. In the region where the rubber latex of the cloth glove 2 is impregnated and solidified, the cloth glove 2 penetrates its stitch and solidifies, and is restrained by the film 3 made of rubber adhered to the cloth glove 2 and the cloth glove 2 and the film glove 2 However, in the permeation-prevention treatment area 4, the coating 3 is not fixed to the cloth glove 2, and the cloth glove 2 is made of the rubber coating 3 just in contact with the outer surface thereof. In the region where the cloth glove 2 and the coating 3 only come into contact with each other without being restricted by the cloth glove 2, the cloth glove 2 and the coating 3 can be individually moved so as to be shifted from each other. Therefore, the work glove 1 can bend smoothly following the movement of the finger, the flexibility of the work glove 1 can be improved, and the movement of the finger when the work glove 1 is worn on the hand can be improved. The degree of freedom is improved, and workability can be improved. Since rubber latex impregnates and solidifies the cloth glove 2 in the remaining area of the cloth glove 2 other than the permeation prevention processing area 4, the remaining area is scratched and pierced by contact with a tool or the like during work. By selecting the remaining area excluding the area that covers the back of the hand, which is susceptible to external action, such as to prevent a decrease in mechanical strength in that area and to make it less likely to be damaged by the external action. Can be.

FIG. 5 is a flowchart showing a procedure of a method of manufacturing a working glove according to an embodiment of the present invention, and FIG. 6 is a view for explaining the procedure shown in FIG. In step a1, the production starts, and the process proceeds from step a1 to step a2. As shown in FIG.
Is attached to a hand mold 5 made of metal or ceramic. From step a2 to step a3, as shown in FIG. 6 (2), a dipping tank 6 having foaming means is filled with rubber latex containing a vulcanizing agent or the like, and the rubber latex is filled with air or the like. After foaming with gas, the cloth glove 2 attached to the hand mold 5 is immersed in the foamed rubber latex for a predetermined time, and then pulled up. At this time, the air bubbles enter the gaps on the outer surface of the cloth glove 2, that is, the gaps between the yarns forming the stitches of the cloth gloves 2 and the gaps between the fibers forming the yarns, and close the gaps. This prevents rubber latex adhering to the outer surface of the cloth glove 2 from entering the gap due to the liquid pressure of the rubber latex when the hand mold 5 is immersed.

The process proceeds from step a3 to step a4, and as shown in FIG. 6 (3), a bubble breaking treatment for breaking bubbles in the rubber latex attached to the outer surface of the cloth glove 2 is performed. At this time, the rubber latex breaks air bubbles that are not solidified by, for example, blowing a gas such as air on the cloth glove 2. The area to be broken is an area excluding the permeation prevention processing area 4. When a gas is blown on the rubber latex that forms bubbles attached to the outer surface of the cloth glove 2, the thickness of the rubber latex film that forms bubbles decreases. When the gas is further blown, the thickness of the film is further reduced and thinned, and the bubbles are broken. The rubber latex around the air bubbles enters the air gap into the air gap closed by the air bubbles. That is, by breaking bubbles of the rubber latex attached to the outer surface of the cloth glove 2, the rubber latex can enter the gap and penetrate into the cloth glove 2, so that the cloth glove 2 is impregnated with the rubber latex. A region to be solidified and a region not to be impregnated can be selectively provided.

The process proceeds from step a4 to step a5. As shown in FIG. 6 (4), the rubber latex after the foam breaking treatment is solidified to form a rubber coating 3 on the outer surface of the cloth glove 2. The solidification of the rubber latex is performed by heating at a predetermined temperature and for a predetermined time. As a result, the rubber latex that has entered the voids in the remaining area of the cloth glove 2 is impregnated into the cloth glove 2 and solidified, and the rubber coating 3 is formed on the outer surface of the cloth glove 2 while being fixed to the cloth glove 2. it can. In addition, the rubber latex in the permeation prevention treatment area 4 solidifies without impregnating the voids, that is, without impregnating the cloth gloves 2, and forms the rubber coating 3 on the outer surface thereof without being fixed to the cloth gloves 2. Can be.

When the thickness of the coating 3 has not reached the predetermined thickness, the cloth glove 2 is immersed in a dipping tank filled with unfoamed rubber latex to be solidified. Repeat, for example, three times until the thickness is reached. Thus, a continuous film is formed on the cloth glove 2. The process proceeds from step a5 to step a6, and a series of procedures is completed. The coating 3 is formed on the cloth glove 2, and the working glove 1 is manufactured.

In another embodiment of the present invention, in the second and subsequent immersion steps, the cloth glove 2 on which the coating 3 has been formed by the first immersion step with the rubber latex in the immersion tank being foamed. May be immersed to produce work gloves.

As described above, since the permeation prevention treatment area 4 is formed in a predetermined area on the outer surface of the cloth glove 2, the area where the cloth glove 2 is impregnated with the rubber latex and solidifies is selectively formed. In the area not impregnated with the rubber latex, the cloth glove 2 and the coating 3 only come into contact with each other, the cloth glove 2 is not restrained by the rubber coating 3, and the cloth glove 2 and the coating 3 are not impregnated. Can be individually moved so as to shift, and the flexibility of the work glove 1 can be improved. Further, since a coating made of rubber is formed on the outer surface of the cloth glove 2, the work glove 1 can be provided with electrical insulation. Further, in the remaining area of the cloth glove 2 except for the permeation prevention treatment area 4, the rubber latex is coated with the cloth glove 2.
To solidify, so that the remaining area is selected as an area that is susceptible to external effects such as scratching and piercing due to contact with tools during work, thereby improving the mechanical strength of that area. In addition, the rubber can be hardly damaged, and the thickness of the rubber can be increased, so that high electrical insulation can be obtained.

Further, since the permeation prevention treatment area 4 is selected as the area covering the back of the hand, even if the user holds the hand while wearing the work gloves 1, the cloth glove 2 and the coating 3 in the area covering the back of the hand
Can be individually expanded and contracted to smoothly bend the work glove 1 following the movement of the finger, thereby obtaining flexibility and improving the freedom of movement of the finger when the work glove 1 is worn. As a result, the hand can be easily gripped while the work glove 1 is worn, and the workability can be improved.

Further, the permeation prevention treatment area 4 is
The air gap formed in the area covering the back of the hand on the outer surface of the cloth glove 2 is closed by air bubbles or the like, so that rubber latex is prevented from entering the gap in the area covering the back of the hand of the cloth glove 2, thereby preventing the penetration of the cloth glove 2. It is possible to prevent the treatment area 4 from being impregnated with the rubber latex and solidified. Further, the cloth glove 2 is immersed in the rubber latex, and the pores in the area are closed with the air bubbles to form the permeation prevention treatment area 4 and the coating 3 is formed. It is possible to easily manufacture the work glove 1 in which the rubber glove 1 that selectively covers the back of the hand and the region that is not impregnated with the rubber latex can be easily manufactured, and the productivity can be improved.

FIG. 7 is a view showing an example of the shape of the permeation prevention processing regions 8, 11, 14, and 17 of the work glove 1. As shown in FIG. FIG.
In (1), the permeation prevention treatment area 8 is formed in an area covering the back of the hand of the work glove 1 and extends in the width direction of the back of the hand,
In addition, a plurality of, for example, three rows are formed at intervals in the direction perpendicular to the width direction. By forming the permeation prevention processing region 8 in this manner, it is possible to easily expand and contract in the direction perpendicular to the width direction of the back of the hand.

In FIG. 7B, the permeation prevention processing area 1
Numerals 1 are formed in a region of the working glove 1 covering the back of the hand, extend in a direction perpendicular to the width direction of the back of the hand, and are formed in a plurality, for example, eight rows, spaced apart from each other in the width direction of the back of the hand. By forming the permeation prevention processing region 11 in this manner, it is possible to easily expand and contract in the width direction of the back of the hand.

In FIG. 7 (3), the permeation prevention processing area 1
Reference numerals 4 are formed in a grid-like manner in a region covering the back of the hand of the work glove 1, for example, eight rows in the width direction of the back of the hand and three rows in a direction perpendicular to the width direction of the back of the hand. Thus, the permeation prevention processing area 14
By forming, it is possible to easily expand and contract in the width direction of the back of the hand and in a direction perpendicular to that direction.

In FIG. 7D, the permeation prevention processing area 1
Reference numeral 7 is formed in a region excluding the distal end portion 18 of each finger of the work glove 1 and the base end portion 19 of the work glove 1. That is, the distal end portion 18 and the proximal end portion 19 are impregnated with the rubber latex and solidified. By forming the permeation-preventing treatment area 17 in this manner, the area where the rubber latex is impregnated and solidified becomes narrower, and in the area where the cloth glove 2 and the film 3 are in contact with each other, the cloth glove 2 and the film 3 are displaced individually. And the flexibility of the working glove 1 can be further improved. Further, since the rubber latex of the distal end portion 18 and the base end portion 19 is impregnated into the cloth glove 2 and solidified, the coating 3 of the distal end portion 18 which is most susceptible to damage such as scratching and piercing during operation is formed. It is possible to increase the thickness of the rubber, to obtain high mechanical strength and high electrical insulation at the distal end portion 18 and to prevent the cloth glove 2 from peeling off the coating 3 when the work glove 1 is removed. Can be prevented.

As still another example, a plurality of fine particles, for example, 1 to 4 are provided in the permeation prevention processing area 17 shown in FIG.
An annular or dot-like impregnation region of about 5 mm may be formed over the entire surface of the permeation prevention treatment region 17. By doing so, it is possible to prevent the cloth glove 2 from further peeling off the coating 3 when the work glove 1 is removed, without impairing the flexibility of the work glove 1.

FIG. 8 is a flowchart showing a procedure of a method of manufacturing a working glove according to another embodiment of the present invention. In the present embodiment, the same reference numerals are given to regions corresponding to the configuration of the above-described embodiment, and description thereof will be omitted.

As a result, the rubber latex that has entered the voids in the remaining area of the cloth glove 2 is impregnated into the cloth glove 2 and solidified, and the rubber coating 3 is formed on the outer surface of the cloth glove 2 while being fixed to the cloth glove 2. The solidified rubber in the permeation prevention treatment area 4 is solidified on the outer surface thereof without being fixed to the cloth glove 2, so that the rubber coating 3 can be formed on the outer surface of the cloth glove 2. When the thickness of the coating 3 has not reached the predetermined thickness, Step b4 and Step b5 are repeated, for example, three times until the thickness of the coating 3 reaches the predetermined thickness. Thus, a continuous film is formed on the cloth glove 2. The process proceeds from step b5 to step b6, and a series of procedures is completed, and the coating 3 is formed on the cloth glove 2 to manufacture a working glove. Even in this case, a working glove having the same effects as the effects of the above-described embodiment can be manufactured.

In the present embodiment, the same reference numerals are given to regions corresponding to the configuration of the above-described embodiment, and description thereof will be omitted. In step d1, manufacturing is started, and in step d1
Then, the process proceeds to step d2, and the cloth glove 2 is attached to the hand mold 5. The process proceeds from step d2 to step d3, in which a masking agent is applied to the permeation prevention treatment area 4 of the cloth glove 2. This masking agent does not dissolve in the rubber latex and can be removed after the rubber latex has solidified, such as proteins, starch, polyacrylic acid, polyacrylamide, polyethylene oxide, polyvinylpyrrolidone, polyvinyl alcohol, polyvinylamide and polyamine. It is a water-soluble polymer compound, and is applied so as to close the voids on the outer surface of the penetration preventing treatment area 4 of the cloth glove 2 in a state where the water-soluble polymer compound is appropriately thickened.

The process proceeds from step d3 to step d4, where the cloth glove 2 coated with the masking agent is dipped in a dipping tank filled with a non-foamed rubber latex containing a vulcanizing agent or the like for a predetermined time. , Pull up.

[0043]

According to the first aspect of the present invention, a rubber latex or a liquid synthetic resin is prevented from penetrating into a predetermined region on the outer surface of a stretchable porous cloth glove mounted on a hand mold. The cloth gloves treated to prevent penetration are immersed in rubber latex or liquid synthetic resin to form the coating on the cloth gloves, so that the cloth gloves are impregnated with rubber latex or liquid synthetic resin. A region to be solidified and a region not to be impregnated can be selectively provided. Therefore, in a region where the rubber latex or the liquid synthetic resin is not impregnated into the cloth glove, the cloth glove and the coating are not adhered to each other. It is possible to move separately from the coating, the cloth gloves and the coating can be offset from each other, increasing the flexibility in this area,
Consequently, the flexibility of the entire work glove can be improved. Further, rubber latex or liquid synthetic resin is impregnated into the cloth glove and solidifies in the remaining area of the cloth glove except for the area where the permeation prevention treatment has been performed. Strength is improved. By selecting the remaining area as an area that is likely to be in contact with a tool or the like during work and is susceptible to external actions such as scratching and piercing, a reduction in mechanical strength of the area is prevented, and the external action is prevented. Can be hardly damaged. Further, since a coating made of rubber and a synthetic resin is formed on the outer surface of the cloth glove, the work glove can be provided with electrical insulation. The remaining region has a large thickness of rubber or synthetic resin, and high electrical insulation can be obtained. As described above, the work gloves are provided with flexibility to improve workability, and can provide excellent mechanical strength and electrical insulation required for work.

According to the second aspect of the present invention, the predetermined area to be subjected to the penetration preventing treatment is selected at least as an area covering the back of the hand, and rubber latex or a liquid synthetic resin is impregnated at least in an area covering the back of the hand. Instead, the remaining area is impregnated with rubber latex or liquid synthetic resin and solidified. Therefore, even if the user holds the hand while wearing work gloves, the cloth gloves and the coating on the back of the hand can move individually in a region where the cloth gloves and the coating come into contact with each other, and the elongation of the coating increases. Since the light does not directly reach the surface of the hand through the cloth glove, the work glove can smoothly follow the movement of the finger and bend the finger. In this way, the flexibility of the working glove is obtained, the degree of freedom of movement of the fingers when the working glove is worn is improved, and the hand is easily gripped with the working glove worn, thereby improving workability. be able to.

According to the third aspect of the present invention, a first aspect is provided.
In the configuration of the described invention, the anti-penetration treatment is performed by removing a gap in a predetermined region on an outer surface of the cloth glove, for example, a gap between fibers forming the cloth glove and a gap in a stitch of the cloth glove, by using a substance such as a bubble, a solidified rubber. Alternatively, it is achieved by closing with a synthetic resin, a particulate substance, or a masking agent, so that the rubber latex or the liquid synthetic resin is prevented from entering the voids, and thereby, the rubber latex or the liquid The impregnation of the synthetic resin can be prevented. Therefore, it is possible to selectively provide a region where the rubber latex or the liquid synthetic resin is impregnated and solidified, and a remaining region where the rubber latex or the liquid synthetic resin is not impregnated. In addition, since the voids are closed with a substance, and the cloth glove is immersed in rubber latex or liquid synthetic resin to form the coating, a region where the rubber latex or liquid synthetic resin is impregnated and solidified and a region where no impregnation is performed are included. Can be easily manufactured, and productivity can be improved.

In the configuration of the invention according to claim 2,
Since the anti-penetration treatment is achieved by closing the gap at least in the region covering the back of the hand on the outer surface of the cloth glove with a substance, the rubber latex or liquid synthetic resin is formed in the gap at least in the region covering the back of the cloth glove. Can be prevented from entering, and thereby, the region of the cloth glove on which the above-mentioned permeation prevention treatment has been performed can be prevented from being impregnated with the rubber latex or the liquid synthetic resin and solidified. Further, by closing the voids in the region with a substance and immersing the cloth glove in rubber latex or liquid synthetic resin to form the coating, a region in which rubber latex or liquid synthetic resin is impregnated and solidified, Working gloves that selectively provide at least a region that is not impregnated with rubber latex or liquid synthetic resin that covers the back of the hand can be easily manufactured, and productivity can be improved.
