Description

  The present invention relates to a glove that can be detected by a metal detector and a method for manufacturing the glove.

  Gloves are used in manufacturing operations in factories such as food manufacturing, electronic device manufacturing, component manufacturing, machine manufacturing, precision device manufacturing, and pharmaceuticals. This is because gloves are necessary for work efficiency, ease of operation, and worker safety. In the use of gloves in such a factory, it is necessary to ensure the hygiene and safety of the food that is the object of work in food production. In order to ensure this hygiene and safety, the operator needs to use gloves.

  Due to the nature of the food that is the object of work, it is not desirable for the operator to touch it with bare hands, and it is desired that the food be handled with gloves that have been sterilized or sterilized. Workers working in food-related factories are required to wear gloves, hair caps and sleeves as well as gloves. In this way, care is taken in food factories so that foods derived from the human body such as hair are not mixed into food.

  An operator performs a work necessary for food production with a gloved hand. In the work, a gloved hand touches the food to be worked on or a member related thereto. By touching with gloves in this way, food hygiene and safety are ensured.

  However, in an operation using such a glove, a part of the glove may be damaged to cause a section. This section may be mixed into food or food containers. In recent food manufacturing, mass production and high-speed line manufacturing are performed for work efficiency, and it is difficult to completely eliminate the occurrence of a section. Similarly, it is difficult to prevent the resulting section from being mixed into the food or the food container, or to remove the mixed section during the work.

  On the other hand, due to the recent increase in consumer awareness and safety awareness, it is not preferred that impurities are mixed in food and food containers. In some cases, the responsibility of the manufacturer may be pursued, and even if the mixed material is a glove section, it tends to be unacceptable to consumers.

  For this reason, manufacturers are striving to prevent broken glove sections from entering the product during factory manufacturing and related work. For example, measures are taken to increase the durability of gloves or to frequently change gloves before they are damaged.

  However, even if such measures are taken, it is difficult to completely eliminate contamination of the glove during work, resulting in a section and mixing with food or containers. This applies not only to foods but also to the manufacture of electronic devices, machines, pharmaceuticals, and the like.

  In this way, when a glove section is mixed in the product, a glove section is mixed by pre-mixing the glove with a magnetic material and measuring the product with a metal detector. Techniques for detection have been proposed (see, for example, Patent Documents 1, 2, and 3).

JP 2009-120974 A Utility Model Registration No. 3149893 International Publication WO2014 / 200047

  Patent Document 1 discloses a glove that is formed of a laminate of a front sheet and a back sheet each formed of a resin material and a resin yarn material, and in which a metal detection material that can be detected by a metal detector is mixed in the back sheet. Disclose.

  In Patent Document 1, a metal detector is mixed in a sheet constituting a glove, and a product in which a broken glove section is mixed is detected by a metal detector. The detected product can be sorted as if the section is mixed. By this selection, it is possible to prevent the product mixed with the section from being put on the market.

  However, in recent factories, the production speed on the production line is increasing in order to improve efficiency and improve cost competitiveness. For this reason, it has become difficult to detect a product manufactured at a high speed with a metal detector in accordance with the speed. This is because it is difficult for a metal detector to detect a minute metal detection material included in a small section when a product including only a small section passes at a very high speed.

  In order to detect a product in which a section is mixed in such a high-speed process, it is conceivable to improve the detection capability of the metal detector. However, the detection capabilities of metal detectors are limited and have difficult aspects. In addition, raising the detection capability increases the cost of metal detectors, leading to increased costs at the factory.

  On the contrary, it is also conceivable to increase the amount and the mixing rate of the metal detection material into the glove that generates the section so that the section can be easily detected by the metal detector. This is because if the mixing rate of the metal detection material into the glove is high, the mixing rate of the metal detection material in the section generated by breakage also increases, and the detection probability of the metal detector increases.

  However, the metal detector is a magnetic material such as metal powder, and there is a problem that the glove becomes hard and stiff when the mixing rate increases. The manufacturing work in the factory requires delicate movements of the hand, and there is a problem that this delicate movement becomes difficult when the gloves become hard. In addition, there is a problem that the fatigue level of the worker is increased. When such a problem arises, there exists a problem that manufacturing capacity and a manufacturing speed will fall.

  Patent Document 2 discloses a glove composed of a main body having a thickness of 0.01 mm to 3 mm formed from rubber, a synthetic resin or a synthetic resin film, in which black iron oxide powder is mixed into the main body.

  In Patent Document 2, similarly to Patent Document 1, a product in which a glove section is mixed can be detected by a metal detector using a glove mixed with iron powder that can be detected by a metal detector.

  However, similarly to Patent Document 1, there is a problem of difficulty in detection and difficulty in dealing with this in high-speed processing.

  Patent Document 3 is a glove that can reduce the minimum detection volume of a glove piece by a metal detector, and the magnetic particles contained in the film are 0.2% by mass or more and less than 40% by mass with respect to the entire film, and are magnetic. The particles disclose a glove comprising secondary particles in which the primary particles are agglomerated.

  Patent Document 3 assumes that a metal detector can detect even when a section is small due to aggregation of magnetic particles.

  However, even if a small section can be detected, as in Patent Documents 1 and 2, there is a problem of difficulty in detection and difficulty in dealing with this in high-speed processing.

  That is, the prior art has the following problems.

  (Problem 1) High-speed processing in manufacturing has exceeded the ability of a metal detector to detect a product mixed with a slice.

  (Problem 2) In order to cope with Problem 1, there is a technical and cost difficulty in improving the ability of the metal detector.

  (Problem 3) Corresponding to problems 1 and 2, raising the mixing rate of magnetic particles into gloves has a limit in terms of workability.

  Because of such problems 1 to 3, it is becoming difficult to balance the need to increase the production speed year by year and the trade-off between detection of glove sections in the product. There's a problem.

  In view of such a problem, an object of the present invention is to provide a glove capable of detecting mixing of a section even at high speed processing without reducing workability.

In view of the above problems, the glove of the present invention is a glove including a layer of a flexible material having a hand shape,
The layer contains magnetic particles,
The content of magnetic particles is non-uniform depending on the part of the layer,
The content rate of magnetic particles in a site that is easily damaged during use of the glove (hereinafter referred to as “specific site”) is higher than the content rate of other sites.

  The glove of the present invention secures workability while reducing hardness and stiffness by increasing the amount of magnetic particles mixed at a site that tends to break and become a section during work. In addition, since the amount of the magnetic particles mixed in the portion that tends to become a section is high, it is possible to easily detect a product mixed with the section.

  In addition, it is possible to easily increase the mixing amount of the magnetic particles depending on the part by contriving with the hand mold for manufacturing the glove, and increase the manufacturing efficiency of the glove.

  As a result, even in a manufacturing process with high-speed processing, a product in which a broken glove section is mixed can be detected by a conventional metal detector, and the safety of the product can be improved.

It is a perspective view of the glove in Embodiment 1 of the present invention. It is a perspective view of the glove in Embodiment 1 of the present invention. It is a perspective view of the glove in Embodiment 1 of the present invention. It is a perspective view of the hand type in Embodiment 2 of the present invention.

  A glove according to a first aspect of the present invention is a glove including a layer of a flexible material having a hand shape, the layer contains magnetic particles, and the content of the magnetic particles is uneven depending on the portion of the layer. The content of magnetic particles in a portion that is easily damaged during use of the glove (hereinafter referred to as “specific portion”) is higher than the content in other portions.

  With this configuration, it is possible to increase the detection accuracy of a portion that is easily broken and easily generates a section. On the other hand, by not excessively increasing the density of the magnetic particles in other parts, the wearability and workability of the entire glove are not impaired.

  In the glove according to the second invention of the present invention, in addition to the first invention, the specific part is at least a part of the fingertip and cuff of the layer.

  With this configuration, the magnetic particle density is high at a site where damage is likely to occur due to work. As a result, it is possible to reliably detect the sections generated from the fingertips and the cuffs that are easily damaged.

  In the glove according to the third invention of the present invention, in addition to the first or second invention, the magnetic particles have a color different from the material of the layer.

  With this configuration, a glove containing magnetic particles can be easily distinguished visually from other gloves.

  In the glove which concerns on 4th invention of this invention, in addition to 3rd invention, a magnetic particle makes the color of a specific site | part differ from the color of another site | part.

  With this configuration, it is possible to grasp at a glance a portion having a high density of magnetic particles.

  In the glove according to the fifth aspect of the present invention, in addition to any one of the first to fourth aspects, the magnetic particles include at least one of iron oxide, chromium oxide, nickel oxide, magnetic stainless steel and alloys thereof. The material.

  With this configuration, the magnetic particles can be contained at a low cost. In addition, the glove section can be reliably detected.

  In the glove according to the sixth invention of the present invention, in addition to any of the first to fifth inventions, the layer is formed by immersing a hand mold having a hand shape in the material liquid. Contains magnetic particles in the main raw material forming the layer.

  In the glove according to the seventh aspect of the present invention, in addition to the sixth aspect, the specific part is immersed in the material liquid more frequently than other parts.

  With this configuration, the thickness of the specific part is increased, and the content of the magnetic particles at the specific part in the thickness direction can be higher than that of other parts.

  In the glove according to the eighth aspect of the present invention, in addition to the sixth aspect, the hand mold includes a magnetic body at a specific portion.

  With this configuration, it is possible to increase the content density of magnetic particles at a specific portion.

  Embodiments of the present invention will be described below.

  (Embodiment 1)

(Analysis by the inventor)
As described in the background art, there has been proposed a technique capable of detecting a section mixed in a product when iron powder or the like is mixed into a resin or rubber glove and the section is cut during work to form a section. However, a section generated by a glove being cut during work is often a minute size, and a section containing iron powder may not be detected by a detection device such as a metal detector.

  When such a small section is generated and mixed in a product such as food, the section may be small and the amount of metal that can be detected by the detection device may be insufficient. Due to this shortage, it is impossible to detect, and it is possible to miss contamination of the glove section.

  In order to prevent this, if the amount of iron powder mixed into the glove is increased, there is a problem that the flexibility of the iron powder exceeds the flexibility of the resin or rubber and the workability of the glove is deteriorated. In the work of factories and the like, a fine work with a gloved hand is necessary, and a glove that is hard and has poor workability cannot cope with this work. On the other hand, if the amount of iron powder is reduced in order to increase the flexibility that is the basis of the workability of gloves, the section detection ability naturally decreases.

  In this way, when iron powder is mixed in a glove in order to detect the contamination of the section produced during the work, the realization of high detection capability and high workability in use are trade-offs. Off relationship.

  Based on such analysis, the inventor searched for an optimal solution in the trade-off, and reached the present invention.

  When used in a manufacturing operation at a factory or the like, there are more frequently used parts and less used parts of gloves depending on the characteristics of hand work. A part where a lot of contact with the product is generated has a high degree of use, and a part where the contact is low has a low degree of use.

  A part where the degree of use is high is a part that is susceptible to wear and wear and is likely to cause a section. On the other hand, the part where the degree of use is low is a part where the degree of wear and wear is low and the section is difficult to occur.

  Based on such an analysis, the inventor is able to use a portion with a high degree of use (that is, a portion that is likely to break a section) and a portion with a low degree of use (that is, a portion that is difficult to cause a section). The idea was to change the amount of magnetic particles to be mixed. Increasing the number of magnetic particles to be mixed in the entire glove will make the entire glove harder, but by changing the amount of magnetic particles to be mixed between the high-use part and the low-use part, the detection ability and work We analyzed that it was possible to achieve a balance between sex and balance.

(Overview)
FIG. 1 is a perspective view of a glove according to Embodiment 1 of the present invention. The glove 1 includes a layer 2 of flexible material having the shape of a hand. Including layer 2 may mean that glove 1 has a plurality of layer structures, one of which is layer 2. In this case, for example, there are a plurality of layer structures in which a resin or rubber layer and a flexible material layer 2 laminated thereon are formed. Alternatively, there is a multiple layer structure in which the layer 2 is formed on a fiber base.

  Alternatively, including the layer 2 includes the case where the glove 1 is formed of only the layer 2. For example, a layer 2 of a flexible material having flexibility such as resin or rubber forms the glove 1. In any case, the glove 1 is formed with part or all of the layer 2.

  The glove 1 has parts such as a fingertip 3, a palm 4, a cuff 5, and a back of a hand 6. These parts correspond to the parts of the user's hand wearing the gloves 1.

  This layer 2 contains magnetic particles. Since the magnetic particles are contained in the layer 2 and are fine, they cannot be illustrated in FIG. The same applies to other drawings. Since the layer 2 contains magnetic particles, as described above, the layer 2 can be detected using a metal detector, a magnetic detector, or the like even when it becomes a slice.

  Here, the content of the magnetic particles is not uniform depending on the portion of the layer 2. The content rate of the magnetic particles in a site that is easily damaged during use of the glove 1 (hereinafter referred to as “specific site”) is higher than the content rate of other sites. As described above, the specific part is a part that is frequently used, such as a part that is frequently used in a gloved work, or a part that is frequently in contact with a product or a machine, and is likely to be worn or worn. .

  A high content means that the amount of magnetic particles contained in a unit volume is larger than the others. Here, since it is the content rate in the site | part in the glove 1, you may grasp | ascertain a content rate with the quantity of the magnetic particle in the unit area in the plane of the glove 1. Or you may grasp | ascertain a content rate with the quantity of the magnetic particle in the thickness direction of the glove 1. In short, it can be grasped as a content rate that the specific part has a larger amount of magnetic particles contained in the generated section of the same size than other parts.

  Of course, such a specific part is easily damaged due to wear or wear, or based on contact with a product. In addition, there are many contacts with the product, and in many of these contacts, breakage is likely to occur, and the resulting section tends to be mixed into the product as it is. For example, when manufacturing food in a food factory, when working while in contact with food, the contacted portion breaks to form a section, and the section is mixed with the food while in contact.

  The glove 1 has a layer 2 containing magnetic particles, but the content of the magnetic particles is higher in this specific part than in other parts, so that the section produced from the specific part is added to the product. Contamination can be detected with high performance and accuracy. This is because even if the section is small, the detection device such as a metal detector is more likely to be detected due to the large amount of magnetic particles. That is, in a specific part where a section is likely to occur, even if the section is fine, the contamination can be reliably detected.

  On the other hand, the content of the magnetic particles other than the specific part is lower than that of the specific part. For this reason, the content rate of the magnetic particles in the entire glove 1 is not necessarily high. By being low in other parts, the content of the magnetic particles in the entire glove 1 is suppressed, and it is prevented that the glove 1 becomes too hard. As a result, the wearing feeling and workability of the entire glove 1 are maintained.

  As described above, the glove 1 according to Embodiment 1 realizes both improvement in the detection rate of the mixed section and improvement in workability by increasing the content of the magnetic particles in the specific part as compared with other parts. Yes.

(Specific part)
The specific part is preferably at least a part of the fingertip 3 and the cuff 5 of the layer 2. The inventor has found that wear and wear at the fingertips 3 and cuffs 5 due to contact with the product, contact at the time of work, etc. in the work with the gloves 1, particularly in the factory work, by various analyzes. It came to mind that it was more likely to occur than other parts.

  This wear or wear is likely to cause breakage, and the fingertips 3 and cuffs 5 are likely to be cut. For example, the fingertip 3 is likely to be worn or worn due to the operation while touching a product or operating an apparatus or a machine in the manufacturing process. The cuff 5 is a part to which a worker applies a force when the glove 1 is worn, the wearing state is adjusted, or the glove 1 is removed. For this reason, it is a site where breakage is likely to occur due to the application of force.

  As described above, the fingertip 3 and the cuff 5 are parts that are particularly liable to be cut during work. In addition, it is also a site where the resulting section is easily mixed into the product as it is. Therefore, by increasing the content of the magnetic particles with at least a part of the fingertips 3 and the cuffs 5 as specific portions, it is possible to detect the mixing of the slices more realistically with a high probability.

  On the other hand, the content of the magnetic particles is limited to at least a part of the fingertips 3 and the cuffs 5, so that the content of other parts is suppressed. For this reason, the content of magnetic particles is not always high throughout the glove 1. For this reason, while raising the detection probability of a section, the flexibility as the glove 1 is lowered and the wearing feeling and workability are not deteriorated.

  In addition, the height of the content rate of the magnetic particles in at least a part of the fingertip 3 and the cuffs 5 that are specific portions may be higher than that in other portions. Or it may be a high content rate compared with the glove containing the conventional iron powder etc. and the detection rate of the mixed section | slice is bad. It is sufficient that magnetic particles are contained in the specific portion at a content rate at which the detection probability can be increased.

  Other parts are, for example, the palm 4 and the back of the hand 6 in FIG. Of course, the finger portion may be a portion other than the fingertip 3, or the cuff 5 may be closer to the palm 4 side. This is because these parts are less damaged than the fingertips 3 and the cuffs 5 to cause a section (particularly, during the operation of wearing the gloves 1) as a comparison. In addition, these other parts are parts that give a feeling of wearing and flexibility during work.

  As described above, it is preferable that at least a part of the fingertip 3 and the cuff 5 is selected as the specific part in the detection of the mixed section and the improvement of workability.

  The specific part is not intended to be limited to at least a part of the fingertip 3 and the cuff 5.

(Specific part color)
Magnetic particles are contained in the layer 2 of the glove 1. At this time, it is also preferable that the magnetic particles have a color different from that of the material of the layer 2. The layer 2 is formed of a flexible material having flexibility. For example, resin and rubber. The magnetic particles are particles made of metal or alloy having magnetism, and are different from the color of the layer 2 so that the glove 1 containing magnetic particles and the glove containing no magnetic particles can be instantly changed. Can be identified.

  For example, when a glove 1 containing magnetic particles must be used or a glove containing no magnetic particles must be used in a manufacturing factory or the like, Even without magnetic detection, it is possible to identify at a glance which glove is used. For this reason, when the glove 1 containing a magnetic particle must be used, there is no mistake.

  This has a high merit for an administrator who prepares the gloves 1.

  In addition, since the color of the magnetic particles is different from the color of the layer 2, the difference in the content of the magnetic particles can be grasped visually. As above-mentioned, content rate is high in a specific site | part. For this reason, the color in a specific part differs from the color with another part. As a result, it is possible to grasp at a glance the difference in the content rate of the magnetic particles and the portion with a high content rate, and the attention in the work can be enhanced.

  In particular, when the specific part is at least a part of the fingertip 3 and the cuff 5, the color of this part can be made different from the color of the other part. FIG. 2 is a perspective view of the glove according to Embodiment 1 of the present invention.

  As shown in FIG. 2, the color tone at the fingertip 3 is different from the color tone of other parts. The operator can grasp at a glance that the content of magnetic particles at the fingertip 3 is higher than that of other parts because the colors are different. By this grasping, it is possible to grasp that the use of the glove 1 with a high detection rate of mixed sections is increased due to increased attention to the work.

  Further, as shown in FIG. 3, it is also preferable that both the fingertip 3 and the cuff 5 are different in color from other parts due to the high content of magnetic particles. FIG. 3 is a perspective view of the glove according to Embodiment 1 of the present invention.

  In the glove 1, the content rate is high in the fingertip 3 and the cuff 5 of the layer 2. Since the color of the magnetic particles is different from the color of the material of the layer 2, as shown in FIG. 3, both the fingertip 3 and the cuff 5 have a different color from other parts. Also in this case, the operator can grasp and identify the gloves 1 having different magnetic particle content at a glance.

  Next, the detail of each part is demonstrated.

(layer)
Layer 2 has the shape of a hand and forms the outer diameter of glove 1. It may be a layer 2 laminated on another layer or a substrate, or the glove 1 may be formed as a single layer. Since layer 2 forms the outer diameter of glove 1, it has the shape of a glove to be worn on the hand.

  This shape varies depending on the use of the glove 1, and the wrist portion is long or short.

  The layer 2 is formed of a flexible material having flexibility. For example, it is resin or rubber, and the following materials are used as examples.

  For example, PVC (polyvinyl chloride), EVA (ethylene vinyl acetate), PP (polypropylene), PE (polyethylene), NR (natural rubber), NBR (acrylonitrile butadiene rubber), CR (chloroprene rubber), SBR (styrene butadiene rubber) ) PU (polyurethane).

(External shape other than layer 2)
The outer shape of the glove 1 may be formed only by the layer 2, and the outer shape may be formed together with other layers and the substrate. The other layer is also formed of a material such as flexible resin or rubber, and may or may not contain magnetic particles.

  Alternatively, a fiber base may be used. The fiber substrate is still flexible, and the layer 2 is formed on the upper layer of the substrate. Even in such a case, the layer 2 contains magnetic particles, and the slice contains magnetic particles. Even if this section is mixed, it can be detected by magnetic particles.

(Magnetic particles)
The magnetic particles are detected by, for example, a metal detector or a magnetic detector. When these magnetic particles are contained in the layer 2, these detectors react to detect a section generated by the damage of the layer 2.

  Here, as the magnetic particles, it is also preferable to use at least one of iron oxide, chromium oxide, nickel oxide, magnetic stainless steel, and alloys thereof as a material. This is because these materials are easily available, are low in cost, and are suitable for containing the necessary amount of magnetic particles in the layer 2.

  In addition, these materials are highly detected by a metal detector or the like, and the probability of detecting a mixed slice increases.

  These magnetic particles are contained in the raw material liquid that forms the layer 2. If the layer 2 is formed with the raw material liquid containing magnetic particles, the layer 2 will be in the state containing these magnetic particles. The magnetic particles contained in the material liquid may be iron oxide, chromium oxide, or the like as described above.

  Of course, materials other than the iron oxide and chromium oxide described above may be used as the magnetic particles.

  Since the magnetic particles are contained in the layer 2 and become the glove 1, it is preferable that the magnetic particles have a small particle size. Further, not only single particles but also aggregated particles in which a plurality of particles are aggregated may exist.

  By including a large amount of such magnetic particles in the layer 2 in the specific part, the glove 1 can increase the detection accuracy of the resulting section without impairing the wearing feeling and workability.

  As described above, the glove 1 according to the first embodiment can increase the detection accuracy of the resulting section without impairing the wearing feeling and workability. As a result, it is possible to suppress the problem of contamination of foreign substances into foods and the like without reducing the production capacity.

  (Embodiment 2)

  Next, a second embodiment will be described. In the glove 1 described in the first embodiment, the content rate of the magnetic particles in the specific part of the layer 2 is higher than in other parts. Such a glove 1 needs to be defined in the manufacturing process.

(Explanation of gloves by manufacturing process)
The glove 1 has a layer 2. This layer 2 contains magnetic particles. In order to form such a layer 2, a hand mold as a prototype of the glove 1 is prepared. Furthermore, a raw material liquid for forming the layer 2 is prepared. The material liquid is a liquid material that is a raw material for the flexible layer 2.

  Moreover, this raw material liquid contains magnetic particles. That is, a liquid raw material liquid is prepared in a state containing magnetic particles. Since the magnetic particles are fine particles, they can be dispersed and contained in the raw material liquid.

  The hand mold is immersed in the material liquid containing the magnetic particles. When the material liquid is applied around the hand mold, the material liquid covers the periphery of the hand mold. When the material liquid covering the periphery of the hand mold is dried, it hardens. When the cured raw material liquid is removed from the hand mold, the layer 2 having a shape and size adapted to the hand mold is manufactured. This layer 2 may be used as the glove 1 as it is, or may be laminated with another layer as the glove 1.

  In this way, the glove 1 including the layer 2 containing the magnetic particles while having flexibility is manufactured.

  Here, the specific part with a high content of magnetic particles is immersed in the material liquid more frequently than other parts. By immersing the material liquid containing the magnetic particles many times in the specific part, the layer containing the magnetic particles is thicker than the other part in the specific part. By increasing the thickness of the layer, the amount of magnetic particles contained in the thickness direction is greater than in other parts. That is, when the thickness direction is taken into consideration, the content of the magnetic particles is higher in the specific part than in other parts.

  For example, as shown in FIGS. 2 and 3, when the fingertip 3 or the cuff 5 is a specific part, the material liquid is immersed in the hand-shaped part that becomes the fingertip 3 or the cuff 5 more times than other parts. You can do it. As a result, the content rate of the magnetic particles at the fingertip 3 and the cuff 5 becomes higher than other parts. The content is high as described above.

  Further, it is also preferable that a part corresponding to a specific part of the hand mold itself is provided with a magnetic body (magnet or the like).

  FIG. 4 is a perspective view of a hand mold according to the second embodiment of the present invention. The hand mold 10 is used when the glove 1 is formed, and has a shape and a size corresponding to the glove 1. The hand mold 10 includes a fingertip portion 13 corresponding to the fingertip 3 that is a specific portion and a cuff portion 15 corresponding to the cuff 5.

  The hand mold 10 is immersed in the raw material liquid, and the layer 2 can be manufactured by covering the periphery with the raw material liquid. Here, the raw material liquid contains magnetic particles.

  As shown in FIG. 4, the fingertip portion 13 that is a specific part is provided with a magnetic material. When the hand mold 10 is immersed in the material liquid, the material liquid contains magnetic particles. The magnetic particles are easily attracted to the fingertip portion 13 by being pulled by the magnetic force of the magnetic material.

  As a result, the material liquid covering the fingertip portion 13 has a higher density of magnetic particles than the material liquid covering other parts. If the raw material liquid is dried and removed from the hand mold 10 in this state, the magnetic particle content density of the fingertip 3 corresponding to the fingertip portion 13 becomes higher than that of other portions.

  In this way, by providing the magnetic body at the portion corresponding to the specific portion of the hand mold 10, the density of magnetic particles in the specific portion of the layer 2 to be manufactured can be easily increased. As a result, the glove 1 described in the first embodiment can be manufactured.

  Next, the manufacturing method of the glove 1 is demonstrated.

  (Manufacturing method: Pattern 1 using a normal hand mold)

(Preparation of material solution)
A liquid raw material liquid for forming the layer 2 is prepared. The raw material of the material liquid is a resin or rubber as described in the first embodiment, and the resin liquid or the rubber liquid is the material liquid. The material liquid is liquid and can be dipped in a hand shape, and has a property of curing after drying.

  It is preferable that the raw material liquid is prepared in a state where the hand mold can be immersed, such as in a state of being accommodated in a container.

  Magnetic particles are added to the raw material liquid. Powdered particles such as iron oxide and chromium oxide are added to the liquid material liquid. After the addition, the raw material liquid is sufficiently stirred. By stirring, the magnetic particles are mixed uniformly.

  In this way, a raw material liquid containing magnetic particles is prepared.

(Immersion process: Pattern 1)
A dipping process is performed in which a hand mold as a prototype of the glove is immersed in the material liquid. By this dipping process, the periphery of the hand mold is covered with the material liquid. Since magnetic particles are mixed in the material liquid, the material liquid containing the magnetic particles covers the periphery of the hand mold.

  Since the hand mold has a hand shape, it matches the shape of the layer 2.

  In the dipping process, dipping is performed a greater number of times at the site corresponding to the specific site of the hand mold than at other sites. For example, at least a part of the fingertip portion corresponding to the fingertip 3 and the cuff portion corresponding to the cuff are immersed more times than the other portions.

  By immersing a large number of times in the fingertip portion and the cuff portion, the thickness of the layer 2 (glove 1) at the fingertip 3 and the cuff 5 increases, and as a result, the content of magnetic particles increases. The increase in content at this thickness increases the content when considering the thickness direction.

(Heating process)
The hand mold with material liquid is heated. By heating, the drying process described later can be improved. In the heating process, application of high-temperature air or installation in a high-temperature room is performed.

(Drying process)
A drying process for drying the material liquid adhering to the hand mold is performed. By the dipping process, the material liquid containing magnetic particles is attached to the hand mold. The material liquid is cured by being dried. By curing, the layer 2 shaped to match the hand shape can be formed.

  These heating steps and drying steps are appropriately performed depending on the material forming the glove 1.

(Removal process)
The layer 2 is formed by the drying process. The removal process which removes this layer 2 from a hand mold is implemented. Since it is dry and hardened, it can be removed from the hand mold. The layer 2 is manufactured by removing.

  In the case where the glove 1 is formed only by the layer 2, the glove 1 is almost completed in this removal process. When other layers are laminated, the above-described dipping process or the like is further performed on the layer 2 or before the formation of the layer 2.

  Manufacturing of the glove 1 is completed by performing necessary post-processing such as coloring.

(Manufacturing method: Pattern 2 Using a magnetic hand mold)
The glove 1 can also be manufactured using the hand mold 10 of FIG. 4 (the hand mold 10 having a magnetic material at a specific portion). Except for the dipping process, the manufacturing process is the same as that described in the pattern 1 manufacturing method.

(Immersion process: Pattern 2)
The hand mold 10 of FIG. 4 has a magnetic material at the fingertip portion 13. The fingertip portion 13 corresponds to the fingertip 3 of the layer 2 (fingertip 3 of the glove 1). This hand mold 10 is immersed in a material liquid containing magnetic particles. Since the fingertip portion 13 of the hand mold 10 includes a magnetic body, this magnetic force attracts the magnetic particles.

  By this pulling, more magnetic particles adhere to the fingertip portion 13. In the adhesion of the same material liquid, the material liquid having magnetic particles having a higher content rate than other parts adheres to the fingertip portion 13.

  If another process is implemented after this immersion process, the glove 1 (layer 2) with the high content rate of the magnetic particle of the fingertip 3 can be manufactured.

  The glove 1 described in the first embodiment can also be obtained by such a method for manufacturing the pattern 2. Not only the fingertip 3 but also the cuff 5 can be realized in the same manner.

  In addition, by adjusting the magnetic force of the magnetic body and the immersion time in the immersion process, the difference in the density of magnetic particles can be variously adjusted.

  As described above, the gloves described in Embodiments 1 and 2 are examples for explaining the gist of the present invention, and include modifications and alterations without departing from the gist of the present invention.
