Description

  The present invention relates to a glove having an environmental resistance that can withstand an external environment such as electric resistance, chemical resistance, water resistance or gas resistance, and a cut resistance that can prevent a cut from occurring in a user's finger. .

  For example, in the work of installing or maintaining an electric cable, it is easy to cut the operator's finger with a conductor or work tool exposed at the end of the electric cable, etc. In addition, gloves with high cut resistance are required. As such a glove, the following glove is disclosed by the patent document mentioned later.

  That is, a glove body is knitted by splicing using a composite fiber having high cut resistance and a synthetic fiber or natural fiber. Here, the composite fiber is a metal wire having a diameter of 13 μm to 35 μm having a thickness of 1 to 3 and a thickness of 50 to 450 denier, and 50 around a core material composed of spliced yarns having a number of 100 to 1000 filaments. A coated fiber of ˜500 denier is wound to form 2 to 3 layers. In addition, the knitting operation is performed such that highly cutable fibers are arranged on the outer surface side of the glove and synthetic fibers or natural fibers are arranged on the inner surface side of the glove. The glove body thus knitted is covered with a hand mold, and the glove body is dipped in a coagulant while supporting the hand mold, and then dipped in a synthetic rubber solution, followed by drying and vulcanization. The outer surface was covered with rubber to obtain gloves.

  Such a glove has a required cut resistance because a metal fine wire is used as the core material of the composite fiber. In addition, since the outer surface of the glove is covered with rubber, it has required electric resistance. Furthermore, since a knitted structure of synthetic fibers or natural fibers is formed on the inner surface side of the glove by splicing yarn, the user of the glove has a good feeling of contact with his / her hand skin.

JP 2012-140749 A

  However, in such a conventional glove, a metal fine wire has to be used for the core material of the composite fiber in order to provide the required cut resistance. Since the metal thin wire has almost no stretchability, it is cut by stretching the composite fiber during the knitting work or the work with the glove attached. Therefore, the above-described spliced yarn is attached to the core material, and the core fibers are further wound around the core material so as to form two to three layers, and the both core materials are bundled. Therefore, much labor and cost are required for the production of the composite fiber.

  Moreover, since the composite fiber is configured to include the above-described core material, the composite fiber lacks stretchability and has high resistance to bending force. Therefore, when wearing gloves knitted using such a composite fiber, there is also a problem that it is difficult to perform fine work.

  On the other hand, the composite fibers that knitting gloves are made up of thin metal wires, so there is also a problem that they are dangerous when used in an environment where high voltage is applied, such as electric cables. It was.

  The present invention has been made in view of such circumstances, and provides a glove having required environment resistance and cut resistance, and having flexibility that allows easy fine work.

  As a result of intensive studies by the present inventors, when a rubber layer is formed on the surface of a knitted structure having high cut resistance, the inventors have obtained the knowledge that the cut resistance of the knitted structure is reduced, and have completed the present invention. .

  That is, (1) A glove according to the present invention is a glove in which an outer surface of a glove body formed by knitting yarn is provided with an environment-resistant layer having a required resistance to the external environment. The first knitted layer disposed on the inside of the glove body and the second knitted layer disposed on the outer surface of the glove body are integrally configured, and the first knitted layer is substantially The second knitting is knitted with a first knitting yarn composed of a chemical fiber having a strength of 2 GPa or more, and the second knitting layer is a second knitting composed of a natural fiber or a chemical fiber having a strength lower than that of the chemical fiber. The environment-resistant layer is formed on the surface of the second knitted layer and on the outer side of the glove body.

  In the glove of the present invention, the glove body formed by knitting the knitting yarn includes a first knitting layer disposed on the inside of the glove body and a second knitting layer disposed on the outer surface of the glove body. And it is comprised integrally. Thus, since the glove body is composed of the first knitted layer and the second knitted layer, it retains flexibility and is constructed integrally, so that a plurality of gloves are worn. Gloves can be worn without complications.

  Here, the first knitted layer disposed on the palm side where the glove is worn, that is, the inside of the glove body is knitted with a first knitting yarn composed of chemical fibers having a strength of approximately 2 GPa or more, so-called super fibers. It is. On the other hand, the second knitted layer disposed on the outer surface of the glove body is knitted with a second knitting yarn composed of natural fibers or chemical fibers having a strength lower than that of the chemical fibers constituting the first knitting yarn. The second knitted layer is more flexible than the first knitted layer. As a result, the entire glove body is configured as flexibly as possible. And the environment-resistant layer which has a required tolerance with respect to an external environment is formed in the area | region of the surface of a 2nd knitting layer, and the said glove body.

  In this way, the first knitted layer disposed inside the glove body is formed of so-called super fibers and is provided with cut resistance. The glove body is separate from the first knitted layer having cut resistance. An environment resistant layer is formed on the surface of the second knitted layer disposed on the outer surface of the. In the glove having such a configuration, even when the blade has reached the first knitting layer through the second knitting layer of the glove body, each of the first knitting layer and the second knitting layer has each. Since it is formed separately, the cutting force does not stay at one place on the first knitting layer but slides on the first knitting layer, and the cutting force applied from the blade to the first knitting layer is dispersed. Is done. Therefore, even when the first knitting layer is knitted using the first knitting yarn composed of super fibers without containing metal or the like, the required cut resistance can be provided.

  On the other hand, since the environment resistant layer is formed on the surface of the second knitted layer, the elasticity and flexibility of the second knitted layer are not impaired by the environment resistant layer. Further, since the first knitted layer does not contain metal or the like, the first knitted layer is excellent in flexibility. Therefore, the glove composed of the glove body including the first knitted layer and the second knitted layer can easily perform fine work. Has the flexibility to be able to.

  Further, (2) the glove according to the present invention is characterized in that the glove body is configured such that the position of the second knitting yarn constituting the second knitting layer can be changed on the first knitting layer. .

  In the glove of the present invention, the glove body is configured so that the position of the second knitting yarn constituting the second knitting layer can be changed on the first knitting layer. When the blade-like body reaches the first knitted layer through the second knitted layer of the glove body as described above, the blade-like body is surely secured to the first knitted layer. It is possible to disperse the cutting force applied to the first knitting layer 11 from the blade-like body by sliding on the surface 11.

  (3) In the glove according to the present invention, the first knitting yarn is made of para-aramid fiber, meta-aramid fiber, ultrahigh molecular weight polyethylene fiber, polyarylate fiber, polyparaphenylene benzoxazole fiber, or carbon fiber. It is characterized by comprising one or more chemical fibers selected from the group.

  In the glove of the present invention, the first knitting yarn is selected from the group consisting of para-aramid fiber, meta-aramid fiber, ultrahigh molecular weight polyethylene fiber, polyarylate fiber, polyparaphenylene benzoxazole fiber, or carbon fiber. Therefore, the first knitted layer can have the required cutability and flexibility.

  On the other hand, (4) the glove according to the present invention is characterized in that the first knitting yarn is composed of a plurality of chemical fibers.

  In the glove of the present invention, the first knitting yarn used for the first knitting layer is composed of a plurality of chemical fibers. Since the adjacent chemical fibers can slide with each other, the first knitting yarn can have the required flexibility without reducing cut resistance.

  (5) The glove according to the present invention is characterized in that the first knitting yarn has a thickness of 300 to 700 denier.

  In the glove of the present invention, the first knitting yarn has a thickness of not less than 300 denier and not more than 700 denier. When the first knitting yarn constituting the first knitting layer is less than 300 denier, the glove having the first knitting layer knitted by the first knitting yarn cannot obtain the required cut resistance. On the other hand, when the first knitting yarn exceeds 700 denier, the first knitting layer knitted by the first knitting yarn has low flexibility, and an operator wearing a glove having the first knitting layer performs fine work. Difficult to do.

  On the other hand, when the first knitting yarn has a thickness of not less than 300 denier and not more than 700 denier, the first knitting layer knitted by the first knitting yarn has flexibility while maintaining the required cut resistance. The worker who wears the gloves having the first knitted layer is easy to perform fine work.

  (6) The glove according to the present invention is characterized in that the first knitted layer and the second knitted layer are knitted so as to be 10 gauge or more and 15 gauge or less.

  In the glove of the present invention, the first knitted layer and the second knitted layer are knitted so as to be 10 gauge or more and 15 gauge or less. When the first knitted layer and the second knitted layer are knitted so as to be less than 10 gauge, both the first knitted layer and the second knitted layer are too thick. The workability of the worker wearing the gloves having the two knitted layers 12 is low. Also, when the first knitted layer and the second knitted layer are knitted so as to exceed 15 gauge, both the first knitted layer and the second knitted layer are too thin, and the required cut resistance is maintained. I can't.

  On the other hand, when the first knitting layer and the second knitting layer are knitted so as to be 10 gauge or more and 15 gauge or less, both high workability and required cut resistance can be maintained.

  On the other hand, (7) the glove according to the present invention is characterized in that the second knitting yarn has a thickness of 60 to 400 denier.

  In the glove of the present invention, the second knitting yarn constituting the second knitted layer has a thickness of 60 denier or more and 400 denier or less. When the second knitting yarn constituting the second knitted layer is less than 60 denier, the stretchability and flexibility of the second knitted layer are insufficient, and there is a possibility of hindering the production of gloves. In addition, when the second knitting yarn exceeds 400 denier, the second knitting layer knitted by the second knitting yarn is distorted, so that the operator wearing the gloves having such a second knitting layer. Workability is low.

  In contrast, when the second knitting yarn has a thickness of 60 denier or more and 400 denier or less, the above-described disadvantage does not occur, and the second knitting layer knitted by the second knitting yarn has flexibility. High and the flexibility of the entire glove is good.

  (8) The glove according to the present invention is characterized in that the second knitting yarn is mixed with a stretchable fiber.

  In the glove of this invention, the 2nd knitting yarn which comprises a 2nd knitting layer is mixing the fiber which has elasticity, such as a wooly nylon fiber, a polyester wooly fiber, or a polyurethane fiber. When fibers having such stretchability are mixed, the stretchability of the second knitting yarn is improved, so that a second knitted layer having greater flexibility can be obtained.

  By the way, (9) the glove according to the present invention is such that the glove body is knitted with the first knitting layer and the second knitting layer by splicing knitting using the first knitting yarn and the second knitting yarn. Features.

  In the glove of the present invention, since the glove body is knitted with the first knitting layer and the second knitting layer by the splicing knitting using the first knitting yarn and the second knitting yarn, the first knitting layer In addition to the second knitted layer, flexibility can be provided between the first knitted layer and the second knitted layer. In addition, when the first knitted layer and the second knitted layer are knitted by splicing yarn, both the knitted layers can be knitted integrally, so that the operation of connecting both the knitted layers is unnecessary, and the first knitted layer is further knitted. Since the layer and the second knitted layer can be formed simultaneously, the production efficiency per unit time is high.

  (10) In the glove according to the present invention, the environment-resistant layer includes a foamed solidified layer formed using a rubber latex foamed on the surface of the second knitted layer, and a rubber latex on the foamed solidified layer. And a rubber layer formed using

  In the glove of the present invention, the environment-resistant layer described above includes a foamed and solidified layer formed using rubber latex foamed on the surface of the second knitted layer. The foamed rubber latex contains a large number of bubbles, and these bubbles interact with the surface of the second knitted layer, so that the rubber latex is prevented from penetrating into the stitches of the second knitted layer. Therefore, the foamed and solidified layer is fixed to the surface of the second knitted layer by sealing without much penetration into the stitches of the second knitted layer. As described above, since the foamed and solidified layer is fixed to the surface of the second knitted layer without penetrating so much into the stitches of the second knitted layer, the stretchability of the second knitted layer is not inhibited by the foamed and solidified layer.

  Thus, since the rubber layer is formed on the surface of the foam coagulation layer fixed to the surface of the second knitted layer, the rubber layer does not affect the stretchability of the second knitted layer. Thereby, it is possible to form an environment resistant layer on the second knitted layer while maintaining the flexibility of the second knitted layer.

It is a partially broken external view which shows an example of the glove which concerns on this invention. It is explanatory drawing explaining the knitting structure | tissue by splicing yarn. It is a flowchart which shows the procedure which manufactures the glove shown in FIG.

The glove which concerns on this invention is explained in full detail based on drawing.
The glove described in the present embodiment is an example for explaining the gist of the present invention, and it goes without saying that the present invention includes modifications and alterations without departing from the gist.

  FIG. 1 is a partially broken external view showing an example of a glove according to the present invention, in which 1 is a glove body knitted in the shape of a human hand. In addition, the cross-sectional part represented by partially breaking the glove is schematically shown for easy understanding, and the thickness direction is emphasized.

  The glove body 1 is configured by superposing at least two knitted layers in the thickness direction of the glove body 1. The first knitted layer 11 disposed inside the glove body 1 has a required cut resistance, and prevents the cut from being generated in the palm by abutting against the palm of the worker wearing the glove. It has become. In addition, the second knitted layer 12 disposed outside the glove body 1 is formed using a crimped yarn or a spun yarn obtained by crimping a filament, and the surface of the second knitted layer 12 is formed as described later. It can be expanded and contracted, and is covered with an environment-resistant layer 2 having resistance to the external environment. The first knitted layer 11 and the second knitted layer 12 are preferably knitted by, for example, splicing knitting shown in FIG.

  FIG. 2 is an explanatory view for explaining a knitted structure by splicing. In spliced yarn knitting, the knitted fabric is made in the same way as flat knitting or rubber knitting, but two knitting yarns are used, and one knitting yarn is knitted so as to cover the other knitting yarn. As described above, in the knitted structure by splicing, one knitting yarn appears on the front (back) side and the other knitting yarn appears on the back (front) side.

  When the first knitted layer 11 and the second knitted layer 12 are knitted by splicing yarn, both knitted layers can be knitted into a flexible structure having elasticity. Accordingly, the first knitting layer 11 and the second knitting layer 12 expand and contract according to the operator wearing the glove bending the finger, so that the resistance to bending force is small, and the worker can easily perform fine work. Can be done.

  Such flexibility is also generated between the first knitted layer 11 and the second knitted layer 12. Even when the blade-like body reaches the first knitted layer 11 through the second knitted layer 12 of the glove body 1, the space between the first knitted layer 11 and the second knitted layer 12 is flexible. The blade-like body slides on the first knitting layer 11 without staying at one place on the first knitting layer 11, and the cutting force applied to the first knitting layer 11 from the blade-like body is dispersed. Thus, even when the first knitted layer 11 is knitted using a knitting yarn not containing metal, it is possible to have the required cut resistance.

  On the other hand, when a knitted layer having cut resistance is arranged on the outside of the glove as in the conventional glove described above and a rubber layer is formed on the surface thereof, the blade-like body is the first knitted. Since the blade 11 does not slip on the layer 11, the blade body remains at one place on the knitting layer, and the cutting force applied from the blade body is concentrated on one place on the knitting layer. Therefore, the knitting layer needs to have a large cut resistance that can resist the cutting force concentrated in one place, and the knitting yarn not containing metal cannot satisfy such a requirement.

  On the other hand, when the first knitted layer 11 and the second knitted layer 12 are knitted by splicing knitting as in the glove body 1 according to the present invention, both the knitted layers can be knitted integrally. Since the first knitting layer 11 and the second knitting layer 12 can be formed simultaneously, the manufacturing efficiency per unit time is high.

  By the way, as the knitting yarn constituting the first knitted layer 11, a so-called super fiber having a strength of about 2 GPa or more and an elastic modulus of about 50 GPa or more (both values are from the Japan Chemical Fibers Association) is used. . Specifically, para-aramid fibers such as Kevlar (manufactured by Toray DuPont), Twaron (manufactured by Teijin Ltd.) or Technora (manufactured by Teijin Ltd.) (both are registered trademarks), Conex (manufactured by Teijin Ltd.) (Registered trademark) meta-aramid fiber, Dyneema or Tsunoga (both manufactured by Toyobo Co., Ltd.) (all registered trademarks), polyarylate fiber such as Vectran (made by Kuraray Co., Ltd.) (registered trademark) , Zylon (manufactured by Toyobo Co., Ltd.) (registered trademark), such as polyparaphenylene benzoxazole (PBO) fiber, or trading card (manufactured by Toray Industries, Inc.), Tenax (manufactured by Toho Tenax Co., Ltd.) or pyrofil (manufactured by Mitsubishi Rayon Co., Ltd.) (Both are registered trademarks) That.

  The knitting yarn is configured such that a plurality of filaments made of one or more types of super fibers have a thickness of 300 to 700 denier. Super fibers are hard and have almost no stretchability. Therefore, when a knitting yarn is composed of a single or a small number of filaments, the knitting yarn is not flexible, but it is configured by bundling more than a few filaments as appropriate. In the knitting yarn, adjacent filaments can slide with each other, so that a knitting yarn having a required flexibility can be obtained. In addition, by configuring the knitting yarn using 100 or more filaments, appropriate flexibility can be provided without reducing cut resistance.

  Here, when the knitting yarn which comprises the 1st knitting layer 11 is less than 300 denier, the glove which has the 1st knitting layer 11 knitted by the said knitting yarn cannot obtain required cut resistance. On the other hand, when the knitting yarn constituting the first knitting layer 11 exceeds 700 denier, the first knitting layer 11 knitted by the knitting yarn has low flexibility, and a glove having the first knitting layer 11 is attached. It is difficult for an operator to perform detailed work.

  On the other hand, as the knitting yarn constituting the second knitting layer 12, a knitting yarn made of a natural material can be used, but when a knitting yarn made of a chemical material is used, the surface of the second knitting layer 12 is used. This is suitable because of its high adhesiveness with the rubber layer 22 coated on the surface. In the case of using a knitting yarn made of a chemical material, in the crimped yarn or the spun yarn, the environment resistant layer 2 (see FIG. 1) provided on the surface of the second knitted layer 12 is the second knitted layer 12. It is suitable because it hardly penetrates into the stitch. Furthermore, in spun yarns made of chemical materials, the fine impression of the spun yarn surface affects the surface of the environment-resistant layer 2, so the appearance impression of the finished gloves is not good. A crimped yarn that can be finished is more preferred. As such a fiber, wooly nylon can be used.

  The knitting yarn constituting the second knitted layer 12 preferably has a thickness of 60 denier or more and 400 denier or less. When the knitting yarn constituting the second knitted layer 12 is less than 60 denier, the stretchability and flexibility of the second knitted layer 12 are insufficient, and there is a possibility of hindering the production of gloves. In addition, when the knitting yarn constituting the second knitting layer 12 exceeds 400 denier, the second knitting layer 12 knitted by the knitting yarn is wrinkled. Therefore, a glove having such a second knitting layer 12 is used. The workability of the worker wearing the is low.

  Furthermore, if the knitting yarn constituting the second knitting layer 12 is mixed with stretchable fibers, the stretchability of the second knitting yarn is improved, and a second knitting layer having greater flexibility can be obtained. Is preferable. As the stretchable fiber, wooly nylon fiber, polyester wooly fiber, polyurethane fiber, or the like can be applied.

  On the other hand, the first knitted layer 11 and the second knitted layer 12 are knitted so as to be 10 gauge or more and 15 gauge or less, preferably 13 gauge. When the first knitting layer 11 and the second knitting layer 12 are knitted so as to be less than 10 gauge, both the first knitting layer 11 and the second knitting layer 12 are too thick. The workability of the worker wearing the gloves having the layer 11 and the second knitted layer 12 is low. Further, when the first knitted layer 11 and the second knitted layer 12 are knitted so as to exceed 15 gauge, both the first knitted layer 11 and the second knitted layer 12 are too thin, and the required cut resistance is obtained. Can not hold.

  On the other hand, when the 1st knitting layer 11 and the 2nd knitting layer 12 are knitted so that it may become 10 gauge or more and 15 gauge or less, it can hold | maintain both high workability | operativity and required cut resistance. In particular, when the first knitting layer 11 and the second knitting layer 12 are knitted so as to be 13 gauge, the workability is the highest.

  By the way, as shown in FIG. 1, the area | region of the surface of the 2nd knitted layer 12 and the outer surface side of a glove is expandable-contracted, and is coat | covered with the environment-resistant layer 2 which has resistance to an external environment. . Here, when the environment-resistant layer 2 penetrates deeply into the stitches of the second knitted layer 12, the stretchability of the second knitted layer 12 is remarkably lowered, so the workability of the operator wearing the gloves is greatly reduced. End up. In the glove according to the present invention, the environment resistant layer 2 having the following configuration is provided, thereby preventing the environment resistant layer 2 from penetrating deep into the stitches of the second knitted layer 12. A flexible glove that retains the stretchability of the second knitted layer 12 can be obtained.

  That is, the foam coagulation layer 21 formed by coagulating the foam rubber latex is formed on the surface of the second knitted layer 12 on the outer surface side of the glove. As will be described later, the foamed solidified layer 21 is formed by immersing the second knitted layer 12 previously impregnated with a coagulant in a foamed rubber latex for 1 to several minutes. The thickness of the foam coagulation layer 21 is preferably 0.3 mm to 0.7 mm, more preferably about 0.5 mm. In addition, what is necessary is just to determine a rubber raw material suitably according to the use of gloves, such as natural rubber or synthetic rubber.

  The foamed rubber latex contains a large number of bubbles, and these bubbles interact with the surface of the second knitted layer 12, so that the foamed rubber latex is prevented from penetrating into the stitches of the second knitted layer 12. Therefore, the foamed solidified layer 21 is fixed to the surface of the second knitted layer 12 while keeping the eye in the stitch of the second knitted layer 12 without much penetration. At this time, when the crimped yarn or the spun yarn is used as the knitting yarn constituting the second knitted layer 12 as described above, it is preferable because the interaction with the bubbles contained in the foamed rubber latex is large.

  In this way, the foamed and solidified layer 21 is fixed to the surface of the second knitted layer 12 without penetrating so much into the stitches of the second knitted layer 12. Is not inhibited.

  And as shown in FIG. 1, the rubber layer 22 is formed in the surface of the foam coagulation layer 21 fixed to the surface of the 2nd knitting layer 12, and the glove is comprised. As will be described later, the rubber layer 22 is formed by immersing the second knitted layer 12 to which the foamed solidified layer 21 is fixed in a rubber latex that is not foamed for several seconds to several tens of seconds. The thickness of the rubber layer 22 is preferably 0.1 mm to 0.9 mm, and more preferably about 0.4 mm to 0.5 mm. In addition, what is necessary is just to determine a rubber raw material suitably according to the use of gloves, such as natural rubber or synthetic rubber.

  As described above, since the rubber layer 22 is provided on the foamed solidified layer 21 that serves to prevent the stitches of the second knitted layer 12, even if the rubber layer 22 is relatively thin, pinholes are formed in the rubber layer 22. There is no risk of occurrence, and the required environmental resistance can be maintained. Moreover, since the environment-resistant layer 2 can be formed with a thickness of about 1 mm even when the foam solidified layer 21 and the rubber layer 22 are combined, there is no wrinkle and high flexibility. Furthermore, as described above, the stretchability of the second knitted layer 12 is also maintained. Accordingly, the glove according to the present invention has the required environmental resistance and cut resistance, and also has the flexibility to easily perform fine work.

  In addition, although the glove body 1 shown in FIG. 1 has been illustrated for the case where it is configured by the first knitting layer 11 and the second knitting layer 12, the present invention is not limited to this, and the first knitting layer 11 and the second knitting layer are also included. One or a plurality of other knitted layers may be provided between the layers 12 or inside the first knitted layer 11. Moreover, each knitting layer including the first knitting layer 11 and the second knitting layer 12 can also be composed of a plurality of knitting tissues superimposed in the thickness direction of the glove body 1. In this case, the knitting structures are connected to each other, while the knitting structures other than the knitting structure arranged on the outermost side are knitted with the super fibers described above.

Next, a method for manufacturing the glove shown in FIG. 1 will be described.
FIG. 3 is a flowchart showing a procedure for manufacturing the glove shown in FIG.

  As shown in FIG. 2, the first knitted layer 11 and the second knitted layer 12 are knitted into a glove shape by splicing knitting to obtain the glove body 1 (step S1). For example, a glove knitting machine SFG (manufactured by Shima Seiki Seisakusho Co., Ltd.) can be used as an apparatus for knitting the first knitted layer 11 and the second knitted layer 12 into a glove shape by splicing. In addition, about the kind and thickness of the knitting yarn which comprises the 1st knitting layer 11 and the 2nd knitting layer 12, the gauge number of the 1st knitting layer 11 and the 2nd knitting layer 12, etc., it implements on each above-mentioned conditions.

  The obtained glove body 1 is attached to a hand mold prepared in advance (step S2). At this time, since the glove body 1 is knitted by splicing knitting and has elasticity, it is possible to easily perform the work of covering the bill.

  A coagulant solution prepared by dissolving calcium nitrate in 50% by volume of methanol was prepared in advance, and the glove body 1 was immersed in the coagulant solution while supporting the hand mold (step S3). The glove body 1 impregnated with the coagulant is dried by holding it in the environment and then at room temperature (step S4).

  Next, for example, a foam rubber latex having the following components is prepared in advance. The foamed rubber latex is produced by weighing each component in the table and putting it in a mixer, and then foaming until the volume reaches 3.5 to 4.0 times by operating the mixer. In the table, “NONOXWSL” is the US I.D. C. It is a trade name of company I, and “Perex TA” is a trade name of Kao Corporation.

  Then, after the glove body 1 supporting the hand mold and impregnated with the coagulant is dipped in the foamed rubber latex for about 1 minute and pulled up (step S5), the surface of the glove body 1 is washed with a water shower. The uncoagulated foamed rubber latex is washed off by the above and air-dried for the next process (steps S6 and S7).

  As a result, the foamed solidified layer 21 is fixed to the surface of the second knitted layer 12 constituting the glove body 1. As described above, the foamed and solidified layer 21 is fixed to the surface of the second knitted layer 12 without penetrating so much into the stitches of the second knitted layer 12. Is not inhibited.

  Next, for example, an unfoamed rubber latex having the following components is prepared in advance. In the table, “Perex SSL” is a trade name of Kao Corporation, and KM71 silicone emulsion manufactured by Shin-Etsu Chemical Co., Ltd. can be used as an antifoaming agent.

  Then, the rubber layer 22 is formed on the surface of the foam coagulation layer 21 by repeating, for example, twice the operation of dipping and lifting the glove body 1 on which the hand mold is supported and the foam coagulation layer 21 is formed in the rubber latex for about 10 seconds. Is formed (step S8). In addition, when using natural rubber latex and isoprene rubber latex, the rubber latex which mixed the former so that it may become 35-65 mass% and the latter becomes 65 mass% -35 mass% can be used. In addition, it cannot be overemphasized that the component of this rubber latex is not restricted to natural rubber latex and isoprene rubber latex. By the way, if necessary, a coagulant may be attached to the surface of the foam coagulation layer 21 in the same manner as before.

  In this way, by forming the rubber layer 22 on the surface of the foamed solidified layer 21, even if the rubber layer 22 is relatively thin as described above, there is no possibility of pinholes occurring in the rubber layer 22, and the required resistance. Environmental properties can be maintained. Moreover, since the environment-resistant layer 2 can be formed with a thickness of about 1 mm even when the foam solidified layer 21 and the rubber layer 22 are combined, there is no wrinkle and high flexibility. Furthermore, as described above, the stretchability of the second knitted layer 12 is also maintained. Accordingly, the glove according to the present invention has the required environmental resistance and cut resistance, and also has the flexibility to easily perform fine work.

  When the formation of the rubber layer 22 in step S8 is completed, the hand layer to which the glove body 1 is attached is transferred to the drying chamber, and the room temperature is raised to about 100 ° C., thereby drying the rubber layer 22 (step S9). ). Next, the rubber layer 22 is vulcanized as necessary (step S10). The vulcanization step can be performed as follows, for example. That is, the hand mold equipped with the glove body 1 is transferred into an indirect vulcanization can and vulcanized at a temperature of about 100 ° C. for about 50 minutes. Thereafter, die cutting is performed to obtain gloves (step S11). The glove thus obtained is subjected to so-called secondary extraction, in which it is washed for several hours in appropriate warm water as necessary.

  In the embodiment for carrying out the present invention, as a method for forming the environment resistant layer 2, the foamed solidified layer 21 is formed on the surface of the second knitted layer 12, and the rubber layer 22 is formed on the surface of the foamed solidified layer 21. However, the present invention is not limited to this, and the rubber latex is prevented from leaking from the stitches of the second knitted layer 12 to the first knitted layer 11 and stays on the surface of the second knitted layer 12. It goes without saying that other methods can be applied if possible.

Example 1
Next, the results of comparative tests will be described.
The comparative test is a cutting force for a plurality of gloves manufactured using a glove body knitted with different types and thicknesses of the first knitting yarn and the second knitting yarn of the first knitting layer and the second knitting layer, Workability and appearance at the time of mounting were carried out. The knitting of the glove body was performed by splicing yarn. Here, the cutting force was measured by the method prescribed in ISO 13997 (JIS T 8052), and the workability and appearance at the time of mounting were determined from the results of actual wearing by the tester and the results of visual observation.

  And the glove which has a required cutting force and workability was made into this invention example, and the glove which did not have the required cutting force and workability was made into the comparative example. Moreover, the result of having implemented the same test about the glove which does not provide the 2nd knitting layer as a control example is shown. In addition, in each glove of the control example, the same operation as before was performed on the first knitted layer to form an environment resistant layer having a foamed solidified layer and a rubber layer.

  The results of the comparative test are shown in Table 3 and Table 4 below. Table 3 shows the results of Examples of the present invention, and Table 4 shows the results of Comparative Examples and Control Examples. Here, in this comparative test, the measured value by the method prescribed | regulated to ISO13997 (JIS T8052) is set to 6.0 N or more as a necessary cutting force about a glove.

  As is apparent from Table 3, in the gloves according to the examples of the present invention, the first knitting yarn constituting the first knitted layer is super fiber in any case, and the thickness is not less than 300 denier and not more than 700 denier. Therefore, the cutting force of 6.0 N or more, that is, the required cut resistance is maintained. In addition, the gloves according to any of the examples of the present invention have good workability, and an operator wearing the gloves can easily perform fine work. In particular, in the glove of Inventive Example 4, since a mixed yarn of nylon fiber and polyurethane fiber is used for the second knitting yarn constituting the second knitting layer, the stretch / flexibility is relatively high, and workability is improved. Was very good. In addition, although it was a little inferior to the workability | operativity of the glove which concerns on the other invention example in the glove of this invention example 4, it was able to fully implement even the fine work. Moreover, in the glove which concerns on the example of this invention, the favorable external appearance was hold | maintained in any case.

  On the other hand, as is clear from Comparative Example 1 shown in Table 4, Dyneema (registered trademark), which includes the first knitting layer and the second knitting layer, and the first knitting yarn constituting the first knitting layer is a super fiber. However, when it was 200 denier, it did not have the required cut resistance. Similarly, as apparent from Comparative Examples 4 and 5, even when the first knitting yarn is Kevlar (registered trademark), which is a super fiber, when 2 or 3 yarns are used with a thickness of 30, the required cut resistance I did not have creativity. Furthermore, as is clear from Comparative Example 3, when the first knitting yarn was not a super fiber, the cut resistance was extremely low.

  On the other hand, as apparent from Comparative Example 2, when the first knitting yarn constituting the first knitting layer was 800 denier, workability was extremely lowered.

  By the way, as apparent from the comparison between Comparative Examples 1 to 3, Invention Example 2 and Comparative Examples 4 and 5, the second knitted layer was not provided, and the environment-resistant layer was formed on the surface of the first knitted layer. The cut resistance of the first knitting yarn, regardless of the type and form of the first knitting yarn, is compared with the cut resistance when the second knitted layer is provided and the environmental layer is formed on the surface of the second knitted layer. Was also low.

  As is clear from Comparative Examples 4 and 5, and Comparative Examples 2 and 3, when a spun yarn of super fiber was used as the first knitting yarn, fine irregularities appeared on the surface of the glove and the appearance was poor. It was a thing.
