Description

  The present invention relates to a glove and a method for manufacturing the glove.

  For example, gloves are used by workers in factories or the like, worn by workers during transport operations, and worn by drivers during driving. As such a glove, there is known a glove in which a plurality of fiber gloves are stacked for the purpose of absorbing or mitigating the impact transmitted to the hand or imparting heat insulation and cold protection.

  As such a plurality of stacked gloves, for example, a glove having a multilayer structure composed of an outer glove formed by coating a woven fabric with a resin and an inner glove made of a woven fabric has been proposed (special feature). (See Kaihei 4-361602). In the glove described in Japanese Patent Laid-Open No. 4-361602, an outer glove and an inner glove on the back side of the hand, and an outer glove and an inner glove on the palm side are sewn on the periphery of the glove.

  However, the glove described in JP-A-4-361602 has a two-layer structure in which the back side of the hand and the palm side are each composed of an outer glove and an inner glove. The part has a four-layer structure. Therefore, the sewn part is inferior in flexibility to the other parts, and especially the finger part has the above four-layer structure on both side surfaces, making it difficult for the finger to bend and performing detailed work with gloves on. There is a risk of hindrance. Moreover, since the glove described in the above-mentioned Japanese Patent Laid-Open No. 4-361602 is only the outer glove and the inner glove are sewn around the glove periphery, the outer glove and the inner glove are working at the palm center part or the like. If you try to grab something while wearing gloves, it will slip between the outer glove and the inner glove, and you may not be able to demonstrate sufficient grip and reduce workability.

JP-A-4-361602

  The present invention has been made in view of these disadvantages, and an object of the present invention is to provide a glove that has heat insulation and cushioning properties and is excellent in grip and flexibility.

The invention made to solve the above problems is
A glove having a multilayer structure,
At least part of the palm area
The first fabric,
A second base fabric superimposed on the first base fabric;
A coating layer obtained by coating a rubber or a resin composition on the surface opposite to the second base fabric side of the first base fabric,
The second base fabric has a plurality of convex portions protruding to the first base fabric side,
The glove is characterized in that the coating layer is impregnated at least up to the tip of the convex portion.

  Since the glove has a multilayer structure including a first base fabric, a second base fabric, and a coating layer in at least a part of the palm region, the glove is excellent in heat insulation and cushioning properties when gripping an object to be gripped. . Further, the convex portion of the second base fabric projects toward the first base fabric side, and the coating layer impregnates at least the tip of the convex portion, whereby the first base fabric and the second base fabric. Are connected via the coating layer. Therefore, it can prevent that a 1st base fabric and a 2nd base fabric slip | deviate during an operation | work, As a result, the outstanding grip force can be provided to the said glove. Furthermore, even if the first base fabric and the second base fabric are connected by the coating layer as described above, the presence of the convex portion causes the cloth-like portion and the first base other than the convex portion of the second base fabric. Since a hollow part (gap) can be present between the cloth and the cloth, a multi-layer structure in which the layers are connected as described above is formed, and the glove has sufficient flexibility.

  In the glove, the first base fabric may be disposed outside and the second base fabric may be disposed inside. Since the coating layer is formed by covering the outer surface of the first base fabric disposed on the outside of the glove, the coating layer comes into contact with the object to be grasped when grasping the object to be grasped. Grip power can be obtained.

  The entire convex portion of the second base fabric is preferably embedded in the coating layer. Thus, since the whole convex part of the 2nd base fabric is embed | buried in the coating layer, the said 1st base fabric and the 2nd base fabric are firmly connected, The 1st base fabric and the 2nd base fabric Misalignment with the cloth can be prevented accurately and reliably.

  As the convex portion, it is preferable to adopt a loop pile. By adopting the convex part of the loop pile, for example, there is a large hollow part between the cloth-like part other than the convex part of the second base fabric and the first base fabric compared to the case of using the cut pile Can be made. That is, for example, when the coating layer is impregnated up to the tip of the convex part (when the base of the convex part is not impregnated), the loop pile is less likely to fall than the cut pile, so the second base fabric It becomes easy to maintain the separation distance between the cloth-like portion other than the convex portion and the first base fabric, and the hollow portion becomes large. Also, for example, when the coating layer is impregnated from the tip of the loop pile in the root direction (for example, when the entire loop pile is embedded in the coating layer), within the loop shape of the loop pile ( A hollow portion (void) is easily formed in a portion surrounded by the loop shape. That is, the coating layer forming material (rubber or resin composition) impregnated from the tip of the loop pile is easily impregnated between the loops (outside of the loop shape), but is hardly impregnated in the loop shape. For this reason, a hollow part is easy to be formed in the loop shape as described above. And if it has a hollow part in a loop shape in this way, the cushioning property of the said glove, a softness | flexibility, and heat insulation will improve more by this hollow part.

  In the glove, the gauge of the second base fabric is preferably 5 gauge or more and 15 gauge or less. By setting the gauge of the second base fabric within the above range, the glove has sufficient strength and durability as a glove, and at the same time, the glove can exhibit excellent flexibility.

In the glove, the pile density of the second base fabric is preferably 25 / inch ² or more and 400 / inch ² or less. By setting the pile density of the second base fabric within the above range, the second base fabric has a sufficient number of piles, and as a result, the glove can exhibit excellent heat insulation and cushioning properties. Here, “book / inch ² ” means the number of loop piles existing in a 1 inch square fabric. Therefore, in the case of a cut pile that is formed by cutting the tip of the loop pile, the number of loop piles that existed before the cut is the pile density. Specifically, when the pile density of the cut pile is “200 / inch ² ”, it means that there are 200 loop piles on the 1 inch square base fabric. The number of cut piles is doubled to 400, which means that 400 cut piles are actually extended from a 1 inch square base fabric.

  The fineness of the fiber used for the second base fabric may be appropriately changed according to the use of the glove, and is preferably 210 dtex or more and 8000 dtex or less, for example. By setting the fineness of the fiber used for the second base fabric within the above range, the glove has sufficient strength and durability, and at the same time, the glove does not get stiff and can exhibit an excellent wearing feeling.

  Moreover, it is good in the pile length of a 2nd base fabric being 0.1 mm or more and 5 mm or less. By setting the pile length of the second base fabric within the above range, a sufficient separation distance can be provided between the first base fabric and the second base fabric. As a result, heat insulation and cushioning properties can be further improved. The “pile length” is the length of the pile extending from the base fabric and means the longest value in a state where the pile is stretched in a straight line.

  The material constituting the coating layer may contain diene rubber as a main component. By using a diene rubber containing a double bond in the main chain of the rubber component as the main component of the material constituting the coating layer, various properties such as elasticity, durability and weather resistance of the coating layer are improved, and the glove The durability and the like are improved. The “main component” means the largest component among the components forming the coating layer.

The invention made to solve the above problems is
A fibrous glove forming step for forming an inner glove having a second base fabric having a plurality of convex portions projecting outward at least in a part of the palm region, and an outer glove having a first base fabric, respectively;
A glove superimposing step of superposing the outer glove on the outer side of the inner glove,
A coating layer forming step of forming a coating layer by coating a rubber or resin composition on at least a part of the palm region of the outer surface of the outer glove,
In the coating layer forming step, a method for manufacturing a glove in which the coating layer is impregnated at least to the tip of the convex portion.

  According to the method for manufacturing a glove, at least the palm region is a first base fabric, a second base fabric superimposed on the first base fabric, and a side opposite to the second base fabric side of the first base fabric. A coating layer obtained by coating a rubber or resin composition on the surface, the second base fabric has a convex portion protruding toward the first base fabric, and the coating layer is at least the convex shape A glove having a multilayer structure that is impregnated to the tip of the part can be manufactured. And as above-mentioned, this glove is excellent in heat insulation, cushioning property, grip property, and a softness | flexibility.

  The “convex portion” in the present invention means a portion protruding from the cloth-like portion of the second base fabric, and in addition to the loop pile and the cut pile described above, such as a filament-like one or a protruding wall. Also included. Further, the second base fabric having such a convex portion is a knitted fabric, a woven fabric, or a so-called three-dimensional solid knitted fabric (for example, Fusion (registered trademark) (manufactured by Asahi Kasei Fibers Co., Ltd.), cubic eye (registered trademark) Unitika Technos), 3D Fabrics (Sumitomo Textile Co., Ltd.), etc.) are also included.

  As described above, the glove is excellent in grip and flexibility while having heat insulation and cushioning properties.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[First embodiment]
The glove 1 of FIGS. 1 and 2 is a glove in which an outer glove made of a first base fabric 2 and an inner glove made of a second base fabric 3 are superimposed. That is, the first base fabric 2 is disposed on the outside, and the second base fabric 3 is disposed on the inside. The second base fabric 3 has a plurality of piles 4 protruding toward the outside (first base fabric 2 side) as convex portions. The glove 1 includes a coating layer 5 in a palm (including a finger) region, a side region, and a finger tip region. The coating layer 5 is obtained by coating a rubber or resin composition on the opposite side of the first base fabric 2 from the second base fabric 3.

<First base fabric>
The said 1st base fabric 2 comprises an outside glove, and what formed this 1st base fabric 2 in the shape of a glove is used as an outside glove. The said 1st base fabric 2 is comprised from the knitted fabric. In addition, the raw material of the 1st base fabric 2 is not limited to a knitted fabric, For example, a woven fabric, a noncombustible fabric, etc. can be used.

  The means for forming the first base fabric 2 in a glove shape is not particularly limited, and for example, seamless knitting that can be knitted without a seam can be used. In addition, it is also possible to use a sewing glove in which the original fabric is extracted into a glove shape with a punching die and stitched into a glove shape, but it is seamless in that it has no stitched portion and is excellent in flexibility as a glove 1. The first base fabric 2 is preferably formed in a glove shape by knitting.

  The thickness of the said 1st base fabric 2 is not specifically limited, For example, it can be 1 mm or less, 0.1 mm or more and 1 mm or less are preferable, More preferably, they are 0.2 mm or more and 0.5 mm or less. When the thickness of the first base fabric 2 is smaller than the lower limit value, the strength of the glove itself is lacking, and the durability may be lowered. On the other hand, when the thickness of the first base fabric 2 is larger than the upper limit value, Workability at the time of wearing decreases. In addition, the thickness of the said 1st base fabric 2 is the average of the result of having measured in arbitrary 5 places within 2 cm circle | round | yen radius of a palm center part using the brand name "Dial Cygness Gauge DS-1211 (made by Niigata Seiki Co., Ltd.)" Can be a value.

  It does not specifically limit as a fiber which comprises the said 1st base fabric 2, Various fibers can be employ | adopted. Examples of such fibers include wooly nylon, polyester fiber, cotton, hemp, rayon fiber, acrylic fiber, aramid fiber, high-strength polyethylene fiber, polyurethane fiber, polyparaphenylene terephthalamide fiber (trade name: “Kevlar (registered) Trademark) ”, manufactured by DuPont, etc.), high-density polyethylene fiber (trade name:“ Dyneema (registered trademark) ”, manufactured by Toyobo Co., Ltd., etc.), or a fiber in which a stainless wire is covered with nylon or the like.

  As a gauge of the said 1st base fabric 2, when producing using a flat knitting machine, for example, 5 gauge or more and 26 gauge or less are preferable, and 13 gauge or more and 26 gauge or less are more preferable. By making the gauge of the 1st base fabric 2 into the said range, it is preferable at the point which does not prevent impregnation with rubber | gum or a resin composition, etc. that the coating layer 5 mentioned later is hard to become so thick that the softness | flexibility of the glove 1 is impaired. In addition, the 1st base fabric 2 has the outstanding softness | flexibility and the touch feeling of the glove 1 becomes so soft that a gauge is made high.

<Second base fabric>
The second base fabric 3 is composed of a knitted fabric. Further, the plurality of piles 4 protruding toward the first base fabric 2 as convex portions are formed of the same fibers as the fibers constituting the second base fabric 3. In addition, as a raw material of the 2nd base fabric 3, it is not limited to the said knitted fabric, For example, a textile fabric, a noncombustible cloth, etc. can be used. And what formed this 2nd base cloth 3 in the shape of a glove is used as an inside glove. In the inner glove, the method of forming the glove shape can be the same as that of the outer glove.

  As a gauge of the said 2nd base fabric 3, when producing with a flat knitting machine, for example, 5 gauge or more and 13 gauge or less are preferable, 7 gauge or more and 13 gauge or less are more preferable, and 7 gauge or more and 10 gauge or less are further more preferable. . By setting the gauge of the second base fabric 3 in the above range, the glove 1 has sufficient strength and durability as a glove, and at the same time, an excellent wearing feeling can be exhibited.

  The fineness of the fibers constituting the second base fabric 3 may be appropriately changed depending on the knitting machine and the type of yarn to be used. For example, wooly nylon is used for the yarn and a 10 gauge pile knitting machine is used. When the double fabric 3 is produced, the ground yarn and the pile yarn are preferably 420 dtex or more and 1000 dtex or less. Similarly, when woolly nylon is used for the yarn and a 7 gauge pile knitting machine is used, The combined yarn and pile yarn is preferably 420 dtex or more and 5000 dtex or less. Similarly, when woolly nylon is used for the yarn and a 13 gauge pile knitting machine is used, the ground yarn and the pile yarn are combined with 210 dtex or more and 560 dtex. The following is preferable. If the fineness of the fibers constituting the second base fabric 3 exceeds the upper limit, it may be difficult to produce the second base fabric 3 due to the influence of the needle bed of the knitting machine, while the lower limit is set. If it is lower, the yarn may break during knitting, and the defective rate of fabric preparation may be improved.

  As the shape of the pile 4, a loop type in which the tip is configured in a loop shape is adopted, but a cut type formed by cutting the tip of the loop pile may be used. These loop piles or cut piles may be subjected to raising treatment.

  The pile length L of the pile 4 is preferably 0.1 mm to 5 mm, more preferably 0.5 mm to 4 mm, and still more preferably 1 mm to 3 mm. By setting the pile length L of the second base fabric 3 within the above range, a sufficient hollow portion 6 is provided between the first base fabric 2 and the second base fabric 3 for the glove 1 to obtain cushioning properties and the like. In addition, the glove 1 can be prevented from becoming too thick. Note that the pile length L of the pile 4 is an average height of the pile 4 in which the loop shape is maintained (excluding a pile having a shape in which the tip of the pile is crushed by the coating layer 5).

The pile density of the pile 4 in the second base fabric 3 is preferably 25 / inch ² or more and 400 / inch ² or less, more preferably 30 / inch ² or more and 200 / inch ² or less, and 35 / inch. ² or more and 150 or less / inch ² is more preferable. By setting the pile density of the pile 4 in the second base fabric 3 within the above range, a sufficient amount of the pile 4 protrudes from the second base fabric 3, and as a result, the glove 1 has excellent heat insulation, cold resistance and It can have cushioning properties.

  The thickness of the said 2nd base fabric 3 is not specifically limited, For example, it can be 2.5 mm or less, 0.2 mm or more and 2 mm or less are preferable, More preferably, they are 0.5 mm or more and 1.8 mm or less. If the thickness of the second base fabric 3 is less than the lower limit, it may be difficult to produce gloves. If the thickness exceeds the upper limit, workability during wearing may be reduced. The thickness measurement is the same as that of the first base fabric 2.

<Coating layer>
The coating layer 5 is formed by coating a rubber or resin composition on the opposite side of the first base fabric 2 from the second base fabric 3. This coating layer 5 impregnates the back surface of the first base fabric 2 and impregnates at least the front end portion of the pile 4 of the second base fabric 3 so that the front end portion of the pile 4 is slightly inward as shown in FIG. Impregnated.

  The rubber or resin composition contains a main component rubber or resin, a solvent and other additives. Examples of the rubber or resin include natural rubber, isoprene rubber, acrylic rubber, chloroprene rubber, styrene-butadiene copolymer, polyurethane resin, acrylonitrile-butadiene copolymer, vinylidene chloride resin, silicone resin, butyl rubber, butadiene rubber, and fluorine. Examples thereof include rubber, chlorosulfonated polyethylene, polyvinyl alcohol, ethylene-vinyl alcohol copolymer, urethane rubber, chlorinated polyethylene, epichlorohydrin rubber, ethylene-propylene rubber, and blends thereof. Among these, natural rubber, isoprene rubber, butadiene rubber, styrene butadiene rubber, chloroprene rubber, acrylonitrile butadiene rubber, diene rubber such as acrylonitrile-butadiene copolymer, and polyurethane resin are preferably used, and acrylonitrile butadiene rubber is economical. It is particularly preferable in terms of processing surface, elasticity, durability, weather resistance and the like.

  Examples of the solvent include water and organic solvents. In particular, latex in which the rubber or resin is dispersed using water as a solvent is preferable. When the main component is acrylonitrile butadiene rubber, examples of the mixture of acrylonitrile butadiene rubber and water include Nipol (registered trademark) Lx-550 (manufactured by ZEON CORPORATION), Nipol (registered trademark) Lx-551 (Nippon ZEON Corporation) A commercially available latex such as PERBUNAN (registered trademark) N LATEX X 1138 (manufactured by Polymer Latex) can be preferably used. By using such a latex, the coating layer 5 can be easily and reliably formed by covering the first base fabric 2.

  In addition, when the main component of the rubber or resin composition is rubber, in order to improve workability and flexibility and strength of the rubber coating, as additives, known metal oxides, vulcanization accelerators, sulfur, It is preferable to add a surfactant, an antioxidant, a pH adjuster, a filler, or the like as appropriate.

  Examples of the metal oxide include zinc oxide, lead oxide, and trilead tetraoxide. These may be used alone or in combination of two or more as required. The compounding amount of the metal oxide is preferably 1 part by mass or more and 3 parts by mass or less with respect to 100 parts by mass of rubber solid content. If the compounding amount of the metal oxide is less than 1 part by mass, the crosslinking is not sufficient, so that it is difficult to obtain the basic properties of tensile strength and modulus. This is because there is a tendency to have a stiff feel when wearing gloves.

  Examples of the vulcanization accelerator include thiuram, dithiocarbamate, thiourea, and guanidine vulcanization accelerators. Of these, dithiocarbamate is preferable. The blending amount of the vulcanization accelerator is preferably 0.5 parts by mass or more and 5.0 parts by mass or less with respect to 100 parts by mass of the solid content of the rubber. When the blending amount of the vulcanization accelerator is less than 0.5 parts by mass, the vulcanization promoting effect is not sufficient, while when the blending amount of the vulcanization accelerator exceeds 5.0 parts by mass, Or the initial vulcanization progresses and a problem such as a scorch phenomenon may occur.

  As a compounding quantity of the said sulfur, 0.1 to 3.0 mass parts is preferable with respect to 100 mass parts of rubber solid content. When the compounding amount of sulfur is less than 0.1 parts by mass, crosslinking is not sufficient, and thus it is difficult to obtain basic properties of tensile strength and modulus (tensile stress). On the other hand, when the compounding amount of sulfur exceeds 3.0 parts by mass , The modulus is too high and tends to be stiff when used as a glove.

  Examples of the surfactant include sodium alkyl sulfate, sodium alkylbenzene sulfonate, sodium naphthalene sulfonate formaldehyde condensate, rosin acid soap, and fatty acid soap. These may be used alone or in combination of two or more as required. The blending amount of the surfactant is preferably 0.1 parts by mass or more and 5.0 parts by mass or less with respect to 100 parts by mass of rubber solid content. If the blending amount of the surfactant is less than 0.1 parts by mass, the stability of the latex tends to be insufficient. On the other hand, if the blending amount of the surfactant exceeds 5.0 parts by mass, the latex becomes too stable and the coating Tends to be difficult to form.

  Examples of the anti-aging agent include naphthylamine, diphenylamine, p-phenylenediamine, quinoline, hydroquinone derivative, monophenol, bisphenol, polyphenol, imidazole, nickel dithiocarbamate, phosphite. , Organic thioacid type, thiourea type compounds and the like. The blending amount of the antioxidant is preferably 0.5 parts by mass or more and 5.0 parts by mass or less with respect to 100 parts by mass of the solid content of the rubber latex. When the blending amount of the anti-aging agent is less than 0.5 parts by mass, it is difficult to obtain a sufficient effect of delaying the deterioration. On the other hand, when the blending amount of the anti-aging agent exceeds 5.0 parts by mass, the degradation is particularly delayed. The effect does not increase, and the strength may decrease.

  As the pH adjuster, alkali, weak acids such as amino acids and acetic acid can be used for the purpose of stabilizing the latex and adjusting the thickness of the coating film. Examples of the alkali include potassium hydroxide and ammonia, and examples of the weak acid include glycine. These may be used alone or in combination of two or more as required. These pH adjusters are preferably added as an aqueous solution before use so as not to impair the stability of the latex. Moreover, it is preferable to adjust pH so that it may become pH 9.0 or more and pH 10.5 or less as pH of rubber | gum before hardening. When the pH of the rubber before curing is less than 9.0, agglomerates begin to be generated. On the other hand, when the pH of the rubber before curing exceeds 10.5, the rubber has excessive alkali and may solidify. .

  Examples of the filler include oxide fillers such as silica, titanium oxide, magnesium oxide, diatomaceous earth, alumina, iron oxide, and tin oxide; carbonate fillers such as calcium carbonate, magnesium carbonate, and zinc carbonate; clay, Aluminum silicates such as caryonite and pyrophyllite; Magnesium silicates such as talc; Calcium silicates such as wollastonite and zonotolite; Silicate fillers such as bentonite, glass beads and glass fibers; Nitride fillers, etc. Is mentioned. These may be used alone or in combination of two or more as required. The blending amount of the filler is preferably 0.1 parts by mass or more and 15 parts by mass or less with respect to 100 parts by mass of rubber solid content. When the blending amount of the filler is less than 0.1 parts by mass, the effect of adding the filler is rarely obtained. On the other hand, when the blending amount of the filler exceeds 15 parts by mass, the stability of the rubber is impaired. There is.

Moreover, a thickener can be added when it is desired to increase the thickness of the coating layer 5. Examples of the thickener include polyacrylic acid-based and cellulose-based thickeners. As for the viscosity of the material for constituting the coating layer 5, the V ₆ value measured with a BH viscometer is preferably 1000 mPa · s or more and 2000 mPa · s or less, more preferably 1300 mPa · s or more and 1700 mPa · s or less. It is. If the viscosity of the material for forming the coating layer 5 is smaller than the lower limit, the thickness of the coating layer 5 may be reduced and sufficient durability may not be obtained. In addition, if the viscosity of the material for forming the coating layer 5 is larger than the above upper limit value, bubbles are likely to be mixed into the material, and a dent or the like is inadvertently formed on the outer surface of the coating layer 5. Durability may be reduced.

  In addition to the above, for example, a plasticizer, a stabilizer, a surfactant, a thickener, a pigment, a colorant, a wetting agent, an antifoaming agent, and the like can be appropriately used as the additive. You may use these individually or in combination of 2 or more types as needed.

  In the glove 1 having the above-described configuration, a multilayer structure including the first base cloth 2, the second base cloth 3, and the coating layer 5 is disposed at least in a part of the palm region. Excellent heat insulation and cushioning. In addition, the pile 4 of the second base fabric 3 protrudes toward the first base fabric 2 and the coating layer 5 impregnates at least the tip of the pile 4 so that the first base fabric 2 and the second base fabric 2 are impregnated. The base fabric 3 is connected via the coating layer 5. Therefore, it can prevent that the 1st base fabric 2 and the 2nd base fabric 3 slip | deviate during an operation | work, As a result, the grip force excellent in the said glove 1 can be provided. Furthermore, even if the first base fabric 2 and the second base fabric 3 are connected by the coating layer 5 as described above, the presence of the pile 4 and the cloth-like portion other than the pile 4 of the second base fabric 3 and the first base fabric 2 The hollow portion 6 can be present between the base fabric 2 and the multilayer structure in which the layers are connected as described above has sufficient flexibility and heat insulation.

  The glove 1 has the first base fabric 2 disposed on the outside, the second base fabric 3 disposed on the inside, and a coating layer 5 formed by coating from the outer surface of the first base fabric 2. Therefore, when the object to be grasped is gripped, the coating layer 5 comes into contact with the object to be grasped, thereby obtaining a sufficient grip force. Further, the coating layer 5 is not impregnated to the inner surface of the second base fabric 3, and the touch is good because the coating layer 5 does not touch the wearer's hand and the second base fabric 3 touches.

  Moreover, since the said glove 1 employ | adopts the loop type pile 4, compared with the case where a cut type thing is employ | adopted, the cloth-like part other than the pile 4 of the 2nd base fabric 3, and the 1st base fabric 2, A large hollow portion 6 can exist between the two. That is, since the loop type pile 4 is less likely to fall than the cut type, it is easy to maintain a separation distance between the cloth-like portion of the second base fabric 3 other than the pile 4 and the first base fabric 2, and the hollow portion. This is because 6 becomes larger. Thus, by increasing the hollow portion 6 between the cloth-like portion of the second base fabric 3 other than the pile 4 and the first base fabric 2, the cushioning property, heat insulating property and flexibility of the glove 1 are further improved. To do.

  Since the glove 1 has a gauge of 5 gauge or more and 15 gauge or less, the glove 1 has sufficient strength and durability as a glove and can exhibit excellent flexibility. it can.

Moreover, since the pile density of the said 2nd base fabric 3 is 25-inch ² or more and 400 pieces / inch ² or less, the said 2nd base fabric 3 will have a sufficient number of piles as a result. The glove 1 can exhibit excellent heat insulation and cushioning properties.

  Furthermore, since the pile length L of the second base fabric 3 is 0.1 mm or more and 5 mm or less, a sufficient separation distance can be provided between the first base fabric 2 and the second base fabric 3. As a result, heat insulation and cushioning properties can be further improved.

  Next, although the manufacturing method of the said glove 1 which consists of the said structure is outlined, the manufacturing method of this invention is not limited to this.

  The manufacturing method of the glove 1 includes a fibrous glove forming step of forming an inner glove having the second base cloth 3 having the pile 4 and an outer glove having the first base cloth 2, respectively, and an outer side of the inner glove. A glove superimposing step of superposing the outer glove, and a coating layer forming step of forming the coating layer 5 by coating the outer surface of the palm region of the outer glove with a rubber or a resin composition.

  The fiber glove forming step is a step of forming an outer glove and an inner glove by knitting a fiber made of wooly nylon or the like into a glove shape. In this fibrous glove forming step, the inner glove is formed such that the pile 4 protrudes from the outer surface of the second base fabric 3.

  In the glove superimposing step, the first base fabric 2 is arranged on the outer side and the second base fabric 3 on the inner side using the three-dimensional hand mold or the like for the outer glove and the inner glove formed in the fibrous glove forming step. It is the process of superimposing so that it may be arrange | positioned. Specifically, an inner glove is put on a three-dimensional hand mold so that a pile ground becomes a surface, and an outer glove is put on the glove so as to overlap.

Further, the coating layer forming step is a step of coating a rubber or resin composition in the first group the outer surface of the fabric 2 as the outermost surface of the glove that the superimposition, and a coating layer-forming material containing a solvent and the like. Specifically, a glove overlaid with a three-dimensional hand mold is impregnated with a coagulant, and then at least the palm region is immersed in the coating layer forming material, and then the gloves are pulled up and heated to vulcanize to form the coating layer forming material. Is a step of forming the coating layer 5.

  Examples of the coagulant used in the coating layer forming step include sodium chloride, calcium chloride, calcium nitrate, and acetic acid. You may use these individually or in combination of 2 or more types. Among these, calcium nitrate is preferable because a coagulation effect can be obtained in a short time. Examples of the coagulant solvent include methanol or water.

  As the concentration of the coagulant, for example, when calcium nitrate is used as the coagulant and methanol is used as the solvent, 0.1% by mass to 0.5% by mass is preferable, and 0.15% by mass to 0.45% by mass. The following is more preferable, and 0.2 mass% or more and 0.4 mass% or less is further more preferable. If the concentration of the coagulant is below the lower limit, the coagulation ability of the coating layer forming material may be reduced, and the coating layer 5 may impregnate the inner surface of the second base fabric 3, while the concentration of the coagulant is When the upper limit is exceeded, the coating layer 5 becomes too thick and the workability is low, or the coating layer forming material is not impregnated to the inside of the first base fabric 2 and the surface of the first base fabric 2 is not impregnated. Only the coating layer 5 is formed, and the first base fabric 2 and the second base fabric 3 may not be bonded.
