  However, conventional heat-resistant gloves are apt to allow high temperature gas such as steam to pass therethrough, and have problems in heat characteristics such as heat resistance and steam barrier properties.

  In order to solve the conventional problems, the present invention provides a heat-resistant glove having high heat characteristics such as heat resistance and high-temperature gas barrier properties.

  The heat-resistant glove of the present invention is a heat-resistant glove including an inner glove, a metal sheet layer, and an outer glove, wherein a metal sheet layer is present on the surface of at least the palm part and palm-side finger part of the inner glove, and the metal sheet An outer glove is present on the surface of the layer, and the outer glove is a glove composed of a heat-resistant fiber thread, and is integrally fixed by a heat-resistant sewing thread from the outer glove to the inner glove.

  The heat-resistant gloves of the present invention have significantly improved heat characteristics such as heat resistance and high-temperature gas barrier properties due to the high-temperature gas shielding effect and heat reflection effect by the metal sheet layer and the heat insulation effect by the inner glove and the outer glove. Further, since the outer gloves and the inner gloves are integrally fixed by heat-resistant sewing threads, the workability is good and the clothes can be washed. A heat-resistant glove in which a wadding layer of heat-resistant fibers is further present between the metal sheet layer and the outer glove and is fixed by quilting exhibits a higher heat insulating effect.

FIG. 2 is a schematic cross-sectional view of the palm portion. FIG. 3 is a schematic cross-sectional view of a finger portion of a heat-resistant glove according to another embodiment of the present invention. FIG. 4 is a schematic cross-sectional view of the palm portion. FIG. 5 is a schematic explanatory view in which a metal sheet layer is partially attached to the surface of the inner glove. FIG. 6 is a schematic explanatory view in which a heat resistant fiber cotton layer is partially laminated on the surface of the metal sheet layer. FIG. 7 is a schematic front view of the heat-resistant glove.

  The present invention is a heat resistant glove including an outer glove composed of an inner glove, a metal sheet layer, and a heat resistant fiber yarn. A metal sheet layer is affixed to the surface of at least the palm part and palm side finger part of the inner glove. The palm part and palm-side finger part are parts that hold a high-temperature object. If at least a metal sheet layer is attached to this part, a high-temperature gas blocking effect and a heat reflection effect can be obtained.

  Outer gloves are laminated on the metal sheet layer, and are integrally fixed by heat-resistant sewing threads from the outer gloves to the inner gloves. Since the outer gloves are gloves made of heat-resistant fibers, they have high heat resistance and a high heat insulating effect. Moreover, since all the layers are integrally fixed by heat-resistant sewing threads, each glove and the metal sheet layer are not displaced, the workability is good, and repeated washing is possible. Quilting is preferable for fixing with a heat-resistant sewing thread. For example, a para-aramid fiber thread is used as the heat-resistant sewing thread.

  The metal sheet layer is preferably formed by laminating a plurality of metal sheet pieces in a scaly manner, and the metal sheet pieces are fixed with an adhesive. When the metal sheet pieces are laminated in a fish scale shape, even if fingers move in a complicated manner, a gap is not formed, the tear is not broken, and workability is also good. In addition, when metal sheet pieces are laminated in a fish scale shape, it becomes a barrier to block heat. The metal sheets are preferably pasted so that two or three sheets partially overlap. A metal sheet piece can be made into arbitrary shapes. Preferably it is triangular. For example, it is an equilateral triangle having one side of about 1 to 5 cm. A large number of these are laminated together to form a fish scale.

  Examples of the metal sheet include an aluminum foil and an aluminum sheet. The thickness of one sheet is preferably 0.1 to 0.5 mm, and more preferably 0.2 to 0.4 mm. The kind, thickness, number of laminated sheets, and the like of the metal sheet can be selected according to the required heat resistance. The adhesive may be any adhesive such as isocyanate, acrylic, epoxy or rubber. Preferably, there is a solventless adhesive that is cured by moisture (humidity) in the air after application, for example, trade name “Super X” manufactured by Cemedine. This adhesive has a heat resistance of 120 to 150 ° C. and becomes a rubber-like viscous material upon heating.

  It is preferable that a heat resistant fiber cotton layer is laminated on the outside of the metal sheet layer, and the inner glove, the metal sheet layer, and the heat resistant fiber cotton layer are fixed by heat resistant sewing threads. The heat-resistant fiber cotton layer exhibits a higher heat insulating effect. The thickness of the wadding layer is preferably 1 to 6 mm, more preferably 2 to 5 mm in a sewn state. The type, thickness, number of laminated layers, and the like of the fiber of the cotton layer can be selected according to the required heat resistance. Since the cotton layer of the heat-resistant fiber is fixed to the inner glove and the metal sheet layer with a heat-resistant sewing thread, deformation or movement does not occur even if the outer glove is covered later. The fixing with the sewing thread is preferably quilted. As the sewing thread, for example, a para-aramid fiber thread is used. This sewing may be as light as a temporary sewing.

  Constituent fibers of outer glove yarns and heat-resistant fibers are comprised of aramid fibers, liquid crystal polyester fibers, polybenzimidazole fibers, polybenzoxazole fibers, polybenzthiazole fibers, polyamideimide fibers, melamine fibers, polyimide fibers, poly It is preferably at least one selected from arylate fiber and glass fiber. These fibers are also called super fibers and have a melting point or decomposition point of about 350 ° C. or higher, preferably 400 ° C. or higher. For example, aramid fiber (melting point or decomposition point of para-aramid: 480 to 570 ° C., meta system: 400 to 430 ° C.), polybenzimidazole fiber (glass transition temperature: 400 ° C. or more), polybenzoxazole fiber (melting point or decomposition) Temperature: 650 ° C.), polybenzthiazole fiber (melting point or decomposition temperature: 650 ° C.), polyamideimide fiber (melting point or decomposition temperature: 350 ° C. or higher), melamine fiber (melting point or decomposition temperature: 400 ° C. or higher), polyimide fiber ( Melting point or decomposition temperature: 350 ° C. or higher), polyarylate fiber (melting point or decomposition temperature: 400 ° C. or higher). Glass fibers can withstand even higher temperatures.

  The outer glove is obtained by knitting a yarn using the heat-resistant fiber into a glove. The heat-resistant fiber yarn is, for example, a covered yarn (CSY), a glass fiber with a para-aramid fiber yarn and a meta-aramid fiber yarn, a para-aramid fiber yarn as a core yarn, and a meta-aramid fiber yarn as a sheath yarn. A twisted yarn of a yarn and a liquid crystal polyester fiber yarn, a covered yarn (CSY) using a glass fiber yarn as a core and a liquid crystal polyester fiber yarn as a sheath yarn can be used. The fineness of the twisted yarn or CSY is preferably about 118 to 11811 dtex (cotton count: 0.5 to 50). A liquid crystal polyester fiber yarn includes, for example, a trade name “Zexion” manufactured by KB Seiren. The back thread of the outer glove can close the knit by heating and shrinking the glove, and can further increase the heat shielding property.

  The inner glove is preferably a glove knitted with a knitted cotton yarn. Cotton gloves absorb sweat and are comfortable to wear. Thin cotton gloves are preferred.

  It is preferable that silicone rubber is disposed in a dot shape on the surface of the outer glove. The dot-like silicone rubber has an effect of delaying heat conduction from a hot object, in addition to the effect that the object to be gripped is difficult to slip. The dot-like silicone rubber is preferably made of a heat-resistant silicone rubber that can withstand up to 390 ° C. This dot-like silicone rubber preferably has a diameter of 1 to 5 mm and a height of 0.5 to 5 mm.

  Leather may be disposed partially or entirely on the surface of the outer glove. The leather is preferably affixed to the portion that comes into contact with the high heat object. The outer glove in which the leather is arranged is preferably integrated by quilting the inner glove after removing the leather part. A glove in which leather is partially bonded to the surface of an outer glove made of heat-resistant fiber yarn is useful as a firefighting glove.

  The heat-resistant glove of the present invention is thin, fits with fingers, does not feel irritating even when a heated object is gripped, has good heat resistance, and has good workability. You can wear this glove and write letters with a ballpoint pen. When working as a steam, for example, as a working glove for cooking using steam or superheated steam, the steam can be cut off and the work of gripping a high-temperature object can be performed efficiently. It is also useful as gloves for cooking such as baking bread and baking pizza. Further, even in the work of handling ceramics, porcelain and other ceramics, the hot air can be blocked, and the work of gripping a high-temperature object can be performed efficiently. Furthermore, it is also useful for heat-resistant gloves used for working with high-temperature objects such as welding work such as arc welding, pre-furnace work such as blast furnaces, working gloves for handling high-temperature objects such as automobile engines, and fire fighting gloves.
