Description

[0001]
[Industrial applications]
The present invention relates to antistatic gloves.
[0002]
[Prior art]
In a factory for manufacturing electronic components such as ICs, workers are charged with static electricity to prevent damage to the electronic components due to the discharge of static electricity charged on the human body and clothes, and to prevent contamination of the electronic components by dust attached to the clothes due to static electricity. Work is being done by wearing clothing that has been treated for prevention. For example, a worker who directly handles electronic components by hand carries out antistatic gloves made of a conductive fiber base material.
[0003]
[Problems to be solved by the invention]
Antistatic gloves are required to have flexibility and elasticity, as well as antistatic properties and conductivity. Therefore, as a conductive fiber base material for antistatic gloves, woven or knitted conductive fibers are used. Cloth or the like is used. Antistatic gloves made of a fibrous base material such as a woven fabric or a knitted fabric are also excellent in air permeability, and thus also have an effect of preventing a worker's hand from getting wet. However, on the other hand, there is also a risk that sweat of the hand will ooze out to the glove surface through the eyes of the fiber base material and contaminate the electronic components.
[0004]
In addition, since static electricity charged on the human body is released through antistatic gloves, if high conductivity is given to gloves for the purpose of obtaining a high antistatic effect, a large amount of static electricity charged on the human body will flow to gloves at once, On the contrary, there is a fear that the electronic component may be damaged.
[0005]
The present invention has been made in view of the above points, and an object of the present invention is to provide an antistatic glove which has solved the above-mentioned conventional disadvantages.
[0006]

Is preferred. In the present invention, the conductivity is preferably provided by polypyrrole.
[0008]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 shows an example of an antistatic glove 1 according to the present invention. In the antistatic glove 1, a hand-shaped upper member 2 and a hand-shaped flat member 3 are superimposed, and as shown in FIG. The peripheral part 4 is joined and integrated, leaving the insertion opening 5. The upper member 2 is made of a stretchable fiber base material 2a, and the flat member 3 is made of a non-breathable material in which a synthetic resin layer 3b is laminated on the surface of the stretchable fiber base material 3a. For the joining and integration of the instep-side member 2 and the peripheral portion of the flat-side member 3, methods such as ultrasonic welding, heat pressing, high-frequency processing, and the like, heat bonding, bonding, sewing, and the like are employed. From the viewpoint of cost, there is no fear of dust adhesion in the manufacturing process.
[0010]
When joining the instep-side member 2 and the flat-side member 3 by heat fusion, a material having heat-fusibility is used for the synthetic resin layer 3b of the flat-side member 3, and the synthetic resin layer 3b side is in contact with the instep-side member 2. As described above, it is preferable that the instep-side member 2 and the flat-side member 3 are overlapped with each other and the peripheral portion is heat-sealed. Usually, after the instep side member and the flat side member are overlapped and the peripheral portion is joined as described above, the folded portion is used so that the joined portion is located on the back side. Accordingly, when the synthetic resin layer 3b is made of a heat-fusible resin and the upper member 2 and the flat member 3 are joined by heat fusion, as shown in FIGS. However, if the synthetic resin layer is not used as a heat-sealing agent and a separate heat-sealing agent is used for the heat-sealing, the synthetic The resin layer 3b can be located on the front side of the glove 1 or on the back side.
[0011]
The stretchable fiber base material 2a forming the upper member 2 and the stretchable fiber base material 3a in the non-breathable material forming the flat member 3 may be a woven fabric, a knitted fabric, or the like having excellent flexibility and stretchability. It is preferable to have uniform and strong adhesion to the synthetic resin layer 3b (adhesion between the elastic fiber base material 3a and the interlayer between the stretchable fiber base material 3a in the non-permeable material constituting the flat side member 3 and the flat side member 2 and the flat side). In order to have the adhesiveness between the instep-side member 2 and the flat-side member 3 when the peripheral portion of the member 3 is heat-sealed, a fiber substrate as smooth as possible is preferable. The filament yarn used for the stretchable fiber base materials 2a and 3a is preferably 30 to 300 denier, particularly preferably 30 to 150 denier, such as wooly-processed acrylic fiber, polyester fiber, and polyamide fiber.
[0012]
The synthetic resin layer 3b of the non-breathable material constituting the flat side member 3 must have elasticity that can follow the elasticity of the fiber base materials 2a, 3a, and also have flexibility when worn as gloves. There is. Further, when the back member 2 and the flat member 3 are heat-sealed using the synthetic resin layer 3b while having excellent adhesiveness to the fiber base material 3a, the heat-sealing property to the fiber base material 2a is improved. You also need to have. In consideration of these, as the synthetic resin constituting the synthetic resin layer 3b when the upper side member 2 and the flat side member 3 are joined by heat fusion, polyester elastomer, polyurethane elastomer, polyvinyl chloride, polyolefin, acrylic A rubber or the like is preferable, and a polyurethane elastomer is particularly preferable. The thickness of the synthetic resin layer 3a is not particularly limited as long as sufficient adhesiveness to the fiber base materials 2a and 3a is obtained and sufficient wearability as a glove is obtained. 30 μm is preferred.
[0013]
When the resin constituting the synthetic resin layer 3a is a polyurethane elastomer, the type of the polyol component constituting the polyurethane elastomer is an important factor that determines the heat-fusibility to the fiber base material 2a. Therefore, particularly when the fiber base material 2a is made of a polyester fiber or a polyamide fiber, the polyol component of the polyurethane elastomer is poly-ε-caprolactone, poly (butylene glycol adipate), poly (hexylene glycol adipate), poly (butylene). Hexylene glycol adipate), poly (3-methylpentanediol adipate), and poly (β-methylvalerolactone glycol) are preferred. These can be used alone or in combination of two or more.
[0014]
As the isocyanate component constituting the polyurethane elastomer, tolylene diisocyanate, 4,4'-diphenylmethane diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, 4,4'-dicyclohexylmethane diisocyanate, lysine diisocyanate, etc., alone or in combination of two or more kinds used.
[0015]
Examples of the chain extender in the polyurethane elastomer include glycols such as ethylene glycol, propylene glycol, butanediol, diethylene glycol and dipropylene glycol, ethylenediamine, isophoronediamine, hexamethylenediamine, propylenediamine, and 4,4′-dicyclohexylmethanediamine. Diamines are used alone or in combination of two or more.
[0016]
The polyurethane elastomer preferably has a thermal softening point of 90 to 200 ° C., but if the pressurizing conditions for heat-sealing the upper member 2 and the flat member 3 are selected, the thermal softening point is further increased. Higher ones can also be used.
[0017]
Polyester can be added to the polyurethane elastomer to improve the lubricity and heat-fusibility of the polyurethane elastomer. Examples of the polyester to be added include polycondensates of glycols such as neopentyl glycol and 1,4-butanediol with dibasic acids such as terephthalic acid, isophthalic acid, sebacic acid and adipic acid. The amount of the polyester added to the polyurethane elastomer is about 5 to 50% by weight, but the amount can be adjusted according to the molecular weight of the polyester. If a large amount of high molecular weight polyester is added, the texture of gloves tends to be hard.
[0018]
As a method of forming the synthetic resin layer 3b made of a polyurethane elastomer or the like on the stretchable fiber base material 3a, a synthetic resin melt extruded film is heat-pressed to the stretchable fiber base material 3a, or a release paper or silicone coating is applied. A method of applying a synthetic resin solution such as a polyurethane elastomer on a polyester film or the like, drying the applied solution, and then applying heat and pressure to bond or using an adhesive to bond the solution. The bonding between the synthetic resin layer 3a and the stretchable fiber base material 3a is preferably a discontinuous bonding state in terms of stretchability and flexibility after the bonding. For this reason, when bonding with an adhesive, it is most preferable to apply the adhesive in a streak-like or spot-like manner.
[0019]
The antistatic glove 1 of the present invention includes at least the back member 2a of the stretchable fiber base material 2a constituting the back member 2 and the stretchable fiber base material 3a of the non-breathable material constituting the flat member 3. In the stretchable fiber base material 2a, the conductivity is given to some or all of the fibers.
[0020]
Conventionally known conductive fibers can be used as the conductive fibers, but it is necessary that the fibers do not impair the elasticity of the elastic fiber base materials 2a and 3a. As the conductive fiber, for example, a conductive fiber integrated with a conductive polymer in a composite manner is exemplified. Examples of the monomer that forms the conductive polymer include anilines, thiophenes, and pyrroles. Examples of pyrroles include pyrrole, 3-methylpyrrole, 3-octylpyrrole, 3,5-dimethylpyrrole, 3-methyl-4-butylesterpyrrole, N-methylpyrrole, and the like, with unsubstituted pyrrole being most preferred. . Suitable as conductive fibers are polyamide, polyester, polyacrylonitrile-based synthetic fibers based on a wooly-processed multifilament yarn, and a conductive material provided with conductivity by being integrated with polypyrrole produced by polymerization of the pyrroles. Fiber.
In the composite spinning conductive fiber, it is necessary to maintain a high fiber strength.In general, the conductive component enters the core component in a core-sheath structure, and the conductivity of the fiber surface becomes low. Although it is poor, the conductive fiber in which polypyrrole is compounded and integrated has extremely excellent static electricity removing performance because the conductive layer is arranged at a portion closest to the outside (for example, on the fiber surface). .
Copper sulfide conductive fibers have a problem of dust generation compared to polypyrrole conductive fibers, and conductive fibers coated with conductive or antistatic paint have poor flexibility and metal-deposited fibers. Is limited by material.
[0021]
The proportion of the conductive fibers in all the fibers constituting the stretchable fiber base material 2a is preferably 5% by weight or more, but sufficient conductivity can be obtained only by mixing the conductive fibers into a part of the stretchable fiber base material 2a. In general, the purpose can be sufficiently achieved by using 5 to 25% by weight of the fibers in the stretchable fiber base material 2a as conductive fibers. Further, a part or all of the stretchable fiber base material 3a used for the non-breathable material constituting the flat side member 3 can be made of conductive fiber. If it is about 20 μm, a sufficient effect can be obtained even if only a part of the fibers of the elastic fiber base material 2a constituting the upper member 2 are made of conductive fibers.
[0022]
When conductive fibers are used as a part of the fibers constituting the stretchable base materials 2a and 3a, conductive fibers that have been subjected to a conductive treatment in advance when manufacturing the stretchable base materials 2a and 3a may be mixed. However, when all the fibers constituting the stretchable fiber base materials 2a and 3a are conductive fibers, in addition to manufacturing the stretchable fiber base material using fibers having conductivity in advance, the stretchable fiber base material may be used. A method of conducting a conductive treatment after forming a material, a method of conducting a conductive treatment after forming a glove, and the like can also be adopted. In addition, a method of further conducting a conductive treatment on a stretchable fiber base material using fibers to which conductivity has been imparted in advance or a glove manufactured from this base material can also be adopted.
[0023]
As a method of imparting conductivity by a monomer that forms a conductive polymer, a monomer that forms a conductive polymer in the presence of an oxidizing polymerization agent is brought into contact with an object to be processed (fiber, stretchable fiber substrate or glove), A method of polymerizing a monomer that forms a conductive polymer to form a composite body of the object and the conductive polymer is exemplified.
[0024]
The method of contacting the object to be treated with the pyrrole-based monomer includes a method of immersing the object to be treated in a treatment liquid containing the pyrrole-based monomer, and a method of exposing the object to be treated in a gas atmosphere of the pyrrole-based monomer to thereby obtain a gas of the pyrrole-based monomer. And the like.
[0025]
Examples of the oxidizing polymerization agent for polymerizing the pyrrole-based monomer include permanganic acid and salts thereof such as permanganic acid and potassium permanganate; chromates such as chromium trioxide; nitrates such as silver nitrate; halogens such as chlorine and bromine. Classes; peroxides such as hydrogen peroxide and benzoyl peroxide; peroxoacids (or salts thereof) such as peroxodisulfuric acid; oxygen acids (or salts thereof) such as sodium hypochlorite; transitions such as ferric chloride Metal chloride; or ferric sulfate, potassium persulfate, ammonium persulfate, ferric perchlorate, and the like.
[0026]
In order to further increase the conductivity imparted to the object to be treated, it is preferable to use a dopant together when polymerizing the monomer forming the conductive polymer. Examples of the dopant include Lewis acids such as phosphorus pentafluoride; hydrochloric acid, sulfuric acid, p-toluenesulfonic acid, 1,5-naphthalenesulfonic acid, dodecylbenzenesulfonic acid, halogenated benzenesulfonic acid, salicylic acid, acetic acid, benzoic acid and the like. Protonic acids and soluble salts thereof; and transition metal compounds such as silver perchlorate and silver borofluoride.
[0027]
In addition, among the oxidative polymerization agents, halogens, peroxo acids (or salts thereof), and transition metal chlorides also function as dopants. Therefore, when these compounds are used as the oxidative polymerization agent, the dopant is intentionally used in combination. Although it is not necessary, when used in combination with a dopant, higher conductivity can be imparted and the conductive polymer layer can be made thinner, which is preferable.
[0028]
In the method of imparting conductivity by immersing an object to be treated in a processing solution containing a pyrrole-based monomer to impart conductivity, (1) the monomer is added to a processing solution containing a pyrrole-based monomer, an oxidizing polymer, and a dopant as necessary. A method of immersing the object to be treated before substantially polymerizing; (2) a treatment solution containing an oxidized polymerization agent and, if necessary, a dopant, and a treatment solution containing a pyrrole-based monomer; And (3) a method of immersing an object to be treated in a treatment liquid to which an oxidative polymerization agent and, if necessary, a dopant are added, and then adding a pyrrole-based monomer to the treatment liquid. In any case, it is preferable to perform the treatment while stirring the treatment liquid.
[0029]
The oxidation polymerization agent is generally used in an amount of about 1 to 3 equivalents based on the pyrrole-based monomer. Further, the concentration of the pyrrole-based monomer depends on the degree of conductivity to be provided, but is preferably about 0.01 to 5% by weight of the fiber weight. When a dopant is used in combination, the dopant is preferably used in an amount of about 0.01 to 0.5 mol per 1 mol of the pyrrole-based monomer.
[0030]
Of the above methods (1) to (3), in the methods (2) and (3), first, the object to be treated is immersed in a solution containing an oxidizing polymerization agent for 20 to 60 minutes, and then contacted with a pyrrole-based monomer. It is preferable to employ The temperature of the treatment liquid when it is brought into contact with the pyrrole-based monomer is preferably 0 to 40 ° C, particularly preferably 0 to 5 ° C, in order to obtain excellent conductivity. The immersion time in the processing solution containing the pyrrole-based monomer varies depending on the concentration of the pyrrole-based monomer and the oxidizing polymerization agent, the desired degree of conductivity, the material and form of the object to be treated, but usually about 30 minutes to 3 hours. It is. Note that a dyeing treatment may be performed on the object to be processed before the conductivity treatment.
[0031]
It is preferable that the conductive treatment is performed using a rotary dyeing machine. The rotary dyeing machine includes a fixed outer body and an inner body configured to be rotatable inside the outer body. The inner body includes a drum type and a washer type, and any type may be used, but a drum type is preferable. When conducting treatment, the treatment liquid is used by injecting about 20 to 90% of the inner volume of the dyeing machine. When the inner body is of a drum type, it is about 50%, and when it is of a washer type, about 60%. It is preferable to implant to a degree. Further, the ratio of the processing liquid to the processing object is preferably 1: 8 to 1:50 in terms of weight ratio.
[0032]
The processing solution and the object to be processed are put in the inner body of the rotary dyeing machine, and the inner body is rotated at a rotation speed of about 3 to 20 revolutions / minute to perform the conductivity treatment. The processing time is preferably about 30 to 240 minutes. Further, at this time, the processing can be performed while alternately reversing the rotation direction of the inner body as necessary. Water is usually used as a solvent in the processing solution containing a pyrrole-based monomer and the like, but aliphatic alcohols can also be used. It is preferable that the dyeing machine is filled with an inert gas such as nitrogen.
[0033]
The antistatic glove 1 of the present inventionThe instep member, the inner surface side of the flat member and the outer surface side of the flat member are provided with electrical conductivity such that the resistance value becomes the instep member <the inner surface side of the flat member <the outer surface side of the flat member,Since the outer surface side (the synthetic resin layer 3b side in the example shown in FIG. 2) of the flat member has a higher resistance than the instep member 2 side, there is no unnecessary conductivity, and it is remarkable only for static electricity removal of the object. effective. Instep member 2Is, Lower resistance than the inner surface of the flat member 3For, Especially excellent in static electricity removal performance,The lower side member 2 with low resistanceEven though the object is farthest from the object, there is an effect that static electricity can be removed. Instep member 2 is 10^Three-10^FourIt is preferable that the flat side member 3 has a conductivity of^Four-10^FiveIt is preferable to have conductivity of about Ω. In order to further remove static electricity, the outer side of the flat member 3Is, 10⁶-10⁸Preferably, conductivity of about Ω is provided..
[0034]
The glove 1 having the resistance value in the order of the upper member 2 <the inner surface of the flat member 3 <the outer surface of the flat member 3 can be manufactured by various methods. For example, a stretchable fiber base material 2a constituting the back side member 2 is provided with a higher conductivity than the stretchable fiber base material 3a constituting the flat side member 3 and the synthetic resin layer 3b. And a stretchable fiber base material 3a having a lower conductivity than the stretchable fiber base material 2a and a lower conductivity than the stretchable fiber base material 3a, or no conductivity. The synthetic resin layer 3b is used so that the synthetic resin layer 3b of the flat side member 3 is on the outside (for example, the upper side member 2 and the flat side member 3 are The gloves 1 may be manufactured such that they are overlapped so as to be in contact with the instep-side member 2 and joined together, and then turned upside down so that the synthetic resin layer 3b is on the outside.
Even if the synthetic resin layer 3b on the outer surface of the flat side member is not provided with conductivity, even if the synthetic resin layer 3b is insulative when dried, it can adsorb moisture in the air and moisture radiated from the user. By providing a possible moisturizing function, antistatic performance in a certain range can be provided even with a high resistance value.
In order to enhance the moisture absorbing and moisturizing functions, for example, a method of increasing the hygroscopicity by using polyethylene glycol for a part of the soft segment of the polyurethane elastomer, a method of using an additive for imparting hygroscopicity, and the like can be mentioned. Cellulose-based fine powder is also used, but collagen fine powder, gelatin fine powder and the like purified from natural leather and the like are particularly remarkable in the effect of adsorbing moisture and dispersing them into the atmosphere. The average particle size is preferably 10 μm or less, and the amount is preferably 1 to 100 parts by weight.
[0035]
Alternatively, after forming the glove shape by the upper side member 2 and the flat side member 3, a conductive treatment may be performed. When the glove-shaped material is subjected to a conductive treatment with a monomer that forms the conductive polymer, the highest conductivity is imparted to the instep-side member 2 to which the processing liquid adheres best because the liquid permeability of the processing liquid is good. Then, the next highest conductivity is given to the stretchable fiber base material 3a of the flat side member 3 having the next good adhesion of the processing liquid, and the stretchable fiber base material 3a of the upper side member 2 and the flat side member 3 is provided. The lowest conductivity is imparted to the synthetic resin layer 3b of the flat member 3 having the lowest adhesion of the processing liquid.
[0036]
In this case, in particular, a polyamide fiber knitted fabric is used as the stretchable fiber base material 2a constituting the upper side member 2, and the stretchable fiber base material 3a made of polyester, polyamide or the like is used as the flat side member 3, and the metal-containing dye and / or the acid If a layer of a synthetic resin layer 3b made of a polyurethane resin that is difficult to be dyed with a dye is used, and the layer is dyed with a gold-containing dye and / or an acid dye in advance and then subjected to a conductive treatment, the adhesion of the conductive polymer is improved. In addition, stable quality is obtained, which is preferable.
[0037]
When conducting the conductive treatment after forming the glove shape, the hand-shaped upper side member 2 and the hand-shaped flat side member 3 are overlapped so that the synthetic resin layer 3b of the flat side member 3 is located inside, and the periphery thereof is formed. A method of obtaining an antistatic glove 1 in the same manner as described above, in which a part is joined and integrated to leave a hand insertion opening to form a glove shape, then subjected to a conductive treatment, and then turned over so that the synthetic resin layer 3b is on the outside, to obtain an antistatic glove 1. The glove-shaped material is turned over so that the synthetic resin layer 3b is on the outside, and then subjected to a conductive treatment to obtain the antistatic glove 1. In the former method, a higher conductivity is imparted to the stretchable fiber base material 3a of the flat side member 3 than in the latter method, while a lower conductivity is imparted to the synthetic resin layer 3b (to the upper member 2). The conductivity imparted is almost the same in any method.) Therefore, when it is desired to impart relatively high conductivity to the stretchable fiber base material 3a of the flat side member 3 and to impart relatively low conductivity to the synthetic resin layer 3b, the former method is preferable, and vice versa. In this case, the latter method is preferred. However, in any of the methods, the resistance value is in the order of the upper member 2 <the inner surface side of the flat member 3 (that is, the elastic fiber base material 3a) <the outer surface side of the flat member 3 (that is, the synthetic resin layer 3b). It does not change that the glove 1 which becomes higher by the above is obtained.
[0038]
In the antistatic glove 1 of the present invention, a part or all of the fibers of the elastic fiber base material 2a constituting the upper member 2 are heat-shrinkable fibers. It is preferable that the heat-shrinkable fibers are heat-shrinked after the portions are heat-sealed. When the heat-shrinkable fibers in the instep member 2 are thermally contracted after the infusion of the instep member 2 and the flat member 3, as shown in FIG. Since the joining position is located on the instep side of the tip of the finger 6, when the electronic component is picked, there is a risk that sweat on the hand leaks out from the air-permeable back side member 2 and contaminates the electronic component. This can be prevented, and the effect of the present invention can be further enhanced.
[0039]
When some of the fibers of the stretchable fiber base material 2a constituting the instep-side member 2 are conductive fibers, even if all or some of the conductive fibers are heat-shrinkable fibers, other than the conductive fibers All or some of the fibers may be heat-shrinkable fibers, or all or some of both fibers may be heat-shrinkable fibers. When the stretchable fiber base material 2a is entirely made of conductive fibers, all of the conductive fibers may be heat-shrinkable fibers, but only some of the conductive fibers have heat-shrinkability, and the remaining The conductive fibers may be non-heat-shrinkable.
[0040]
The above-mentioned heat-shrinkable fiber is not limited to a fiber that causes only simple fiber length contraction by heat, and may be a heat-crimpable fiber that causes crimping. Methods for imparting heat shrinkability and heat crimpability to fibers include adjusting the polymer composition of the fiber, spinning conditions, heat setting conditions, twisting yarns, and heat shrinkage as in side-by-side type fibers. And a method of forming sea-island fibers and core-sheath fibers. For example, as the side-by-side type fiber, a polyester fiber obtained by combining polyesters having different molecular weights, chemical structures, crystallinities and the like can be exemplified.
[0041]
Next, specific examples of the antistatic glove 1 of the present invention will be described.
[0042]
Example 1
Circular knitted jersey (28 gauge / 30 inch diameter) consisting of 84 50D / 24F wooly-processed polyester yarns and 6 150D / 60F acrylic yarns (conductive yarns having a resistance value of 0.1 kΩ, which has been conductively processed with polypyrrole). ) Is processed into a hand shape, and two sheets are prepared. One sheet is directly used as the back side member, and the other sheet is formed with a 28 μm thick polyurethane elastomer layer on the surface (formed by a transfer method using release paper). It was a flat member. The upper side member and the flat side member were overlapped, and the peripheral portion was fused by high frequency processing leaving a hand insertion opening to obtain a glove. The friction band voltage of this glove was substantially 0V. In addition, while handling the electronic parts while wearing the gloves, the electronic parts and the like were not contaminated by sweat of the hands.
[0043]
Example 2
Gloves were manufactured in the same manner as in Example 1 except that only the circular knitted sheeting constituting the back member replaced 30% of the wooly-processed polyester fiber with heat-shrinkable polyester fiber (50% shrinkage at 130 ° C.). . In addition, after the periphery of the back side member and the flat side member were fused by high-frequency processing, the heat-shrinkable polyester fiber in the back side member was thermally shrunk. The frictional charge voltage of the obtained glove was substantially 0V. In addition, when the electronic components were handled while wearing the gloves, contamination of the electronic components and the like due to sweat from hands was reliably prevented.
[0044]
Example 3
Using a 50D / 17F polyamide wooly-processed circular knitted Alaska as the instep side member, a 15 μm polyurethane elastomer (Resamine: manufactured by Dainichi Seika Kogyo Co., Ltd.) having excellent heat-sealing properties on a 50D / 17F polyamide circular knitted Alaska. Gloves were manufactured by an ultrasonic welder method using a laminate obtained by laminating with a polyurethane adhesive (Chris Bon: manufactured by Dainippon Ink and Chemicals, Inc.) through a release paper transfer method.
Subsequently, Acidol Green (manufactured by BASF) was dyed according to a conventional method so that the polyurethane and the polyamide had a uniform hue, and then polypyrrole was adjusted to 0.035 μm with a mixed aqueous solution of ferric chloride, paratoluenesulfonic acid, and pyrrole. To give conductivity.
The obtained glove has a back side member surface 10³Ω, outside of flat side member 10⁶Ω, inside the flat side member 10⁵Ω (two-ended needle method), which was excellent for antistatic work.
[0045]
Example 4
A collagen powder having an average particle size of 3 μm obtained by pulverizing cowhide is dispersed at a solid content ratio of 100/20 with respect to the same polyurethane elastomer as in Example 3, and the film thickness becomes 15 μm on a smooth release paper. And then coated with a two-component polyurethane adhesive (same as that used in Example 3) so as to have a film thickness of 15 μm, and 50D / 17F Woolly nylon Amanakasa was attached. Gloves were manufactured by high-frequency fusion processing using a sufficiently cured product as a flat member and a wooly nylon Amakasa as a back member. Next, it was immersed in a treatment solution containing ferric chloride, p-toluenesulfonic acid, and pyrrole at 18 ° C. for 240 minutes to obtain an antistatic glove. The obtained one is the outer member 10 of the flat side member.⁸Ω, inside the flat side member 10⁶Ω, back side member surface 10⁴Ω, which was suitable as antistatic work gloves.
[0046]
【The invention's effect】
As described above, the antistatic glove of the present invention has excellent antistatic properties because at least a part or all of the fibers in the stretchable fiber base material constituting the instep-side member are excellent in antistatic properties. Since the member is made of a non-breathable material, leakage of hand sweat and the like is prevented, and there is an effect that there is no risk of contaminating electronic components and the like by the sweat and the like.
[0047]
The flat member has a higher resistance value on the outer surface than on the inner surface.ByIt is an antistatic glove with no conductivity more than necessary, mainly for removing static electricity, and the upper side member has a lower resistance value than the inner surface side of the flat side memberByThis has the effect of being particularly excellent in antistatic properties.MoreoverConductivity is also given to the outer surface side of the flat side memberBy doing so,Direct contactNever doThere is an effect that static electricity can be removed on the back side at a distance.
[0048]
Moreover, if a part or all of the fibers of the stretchable fiber base material constituting the instep-side member are made heat-shrinkable, and the heat-shrinkable fibers are heat-shrinked after joining the instep-side member and the peripheral portion of the flat-side member. Since the joint portion between the back side member and the flat side member is located on the back side of the fingertip, leakage of sweat and the like at the fingertip is further prevented.
