Description

Gloves

[0001] The present invention relates to gloves comprising a glove body and a polyvinyl chloride resin layer.

[0002] Conventionally, gloves comprising a glove body composed of a plurality of threads and a polyvinyl chloride resin layer have been widely used. This glove is provided with water resistance, acid resistance, alkali resistance, solvent resistance, flame retardancy, electrical insulation, etc. by the polyvinyl chloride resin layer. Also, on the inner surface side of this glove, the fibers of the threads constituting the glove body provide a soft and comfortable touch to the wearer's hand.

[0003] Conventionally, gloves comprising a glove body and a polyvinyl chloride resin layer may be manufactured by a coating process. In the coating process, a resin solution containing a polyvinyl chloride resin is applied to the outer surface side of a glove body (hereinafter also referred to as "raw glove") at a stage when the resin layer has not yet been applied, dried, and a polyvinyl chloride resin layer is formed on the outer surface side to manufacture the glove. However, in the conventional coating process, in order not to impair the soft and comfortable touch by the fibers on the inner surface side of the glove, it is necessary to form the polyvinyl chloride resin layer on the outer surface side of the glove body so that the polyvinyl chloride resin does not penetrate to the inner surface side of the glove body. For this reason, in the conventional coating process, generally, a fluorine-based oil repellent is added to the glove body and then a polyvinyl chloride resin composition is applied to the outer surface side of the glove body.

[0004] Alternatively, gloves comprising a glove body and a polyvinyl chloride resin layer may be manufactured by a dipping method. In the dipping method, a hand is immersed in a resin paste containing polyvinyl chloride resin, the hand is removed from the resin paste, the hand with the resin paste adhering to its outer surface is dried, and a polyvinyl chloride resin layer is formed on the outer surface of the hand, thereby manufacturing the glove. The resin paste used in the dipping method has a higher viscosity than the aforementioned resin solution used in the coating method and does not easily penetrate to the inner surface of the glove body. For this reason, the dipping method has the advantage of not requiring the use of fluorine-based oil repellents. For example, Patent Document 1 discloses a method for manufacturing a polyvinyl chloride paste resin powder. In this manufacturing method, a polyvinyl chloride paste resin obtained by polymerizing a polyvinyl chloride monomer in an aqueous medium is crushed and then heat-treated to obtain a specific surface area of ​​7 to 100 m². ２ This is a method for producing a vinyl chloride-based paste resin characterized by having a concentration of / g. Patent Document 1 states that this method can produce a paste sol with excellent non-penetration properties for fabrics and good adhesion to fabrics, as well as a cloth glove coated therewith.

[0005] Japanese Patent Application Publication No. 2007-284512

[0006] However, in recent years, concerns have been raised about the potential for fluorine-based water and oil repellents to accumulate in living organisms and cause environmental pollution, leading to requests to refrain from using them. Furthermore, the polyvinyl chloride paste sol obtained by the manufacturing method described in Patent Document 1 has a considerably higher viscosity than the resin solution, making it difficult to penetrate between the threads in the glove body. Because it is difficult to penetrate in this way, the glove body and the polyvinyl chloride resin layer do not adhere well, and when the gloves are used repeatedly, the polyvinyl chloride resin layer tends to peel off from the gloves unintentionally.

[0007] Therefore, the object of the present invention is to provide a glove comprising a glove body and a polyvinyl chloride resin layer, wherein the polyvinyl chloride resin does not easily penetrate to the inner surface of the glove body, and the polyvinyl chloride resin layer does not easily peel off the glove.

[0008] To solve the above problems, a glove according to one embodiment comprises: a glove body composed of a plurality of threads, each thread containing at least one fiber; at least one acrylic resin layer formed on at least a part of the outer surface of the glove body and composed of an acrylic resin composition containing a (meth)acrylic resin; and a polyvinyl chloride resin layer formed on at least a part of the outer surface of the at least one acrylic resin layer and composed of a polyvinyl chloride resin composition containing a polyvinyl chloride resin.

[0009] In such gloves, the at least one acrylic resin layer is formed between the glove body and the polyvinyl chloride resin layer. Therefore, when forming the polyvinyl chloride resin layer, the polyvinyl chloride resin is prevented from penetrating to the inner surface of the glove body by the at least one acrylic resin layer. Furthermore, the at least one acrylic resin layer adheres easily to both the multiple threads constituting the glove body and the polyvinyl chloride resin layer.

[0010] As described above, in a glove comprising a glove body and a polyvinyl chloride resin layer, it is possible to provide a glove in which the polyvinyl chloride resin does not easily penetrate to the inner surface of the glove body, and the polyvinyl chloride resin layer does not easily peel off from the glove.

[0011] Figure 1A shows the appearance of a glove according to one embodiment when viewed from the back of the hand. Figure 1B shows the appearance of a glove according to one embodiment when viewed from the palm side. Figure 2 is a schematic cross-sectional view showing the cross-section of a portion of a glove according to one embodiment that has a four-layer structure consisting of the glove body, a first acrylic resin layer, a second acrylic resin layer, and a polyvinyl chloride resin layer, when cut in the thickness direction of this four-layer structure. Figure 3 is a flowchart illustrating a plurality of steps that may be included in the manufacturing method of a glove according to one embodiment.

[0012] Hereinafter, a glove according to one embodiment and a method for manufacturing the glove according to one embodiment will be described with reference to the drawings. The dimensions such as the size and aspect ratio of each component in the illustrated glove, the positional relationships between components, etc. are illustrative and not limited to those shown in the illustration. In this specification, for example, "mass%" and "weight%" are synonymous, and "parts of mass" and "parts of weight" are synonymous. Also, when the expression "~" is used in this specification, it is used to include the numerical value or physical property value before and after it.

[0013] As shown in Figures 1A and 1B, the glove 10 according to one embodiment comprises a glove body 20, at least one acrylic resin layer 30, and a polyvinyl chloride resin layer 40.

[0014] The glove body 20 has a pouch portion 21 that is shaped like a bag to cover the back of the wearer's hand and palm when the glove 10 is worn. The pouch portion 21 has a back portion 212 that is shaped to cover the back of the wearer's hand and a palm portion 211 that is shaped to cover the wearer's palm. The glove body 20 may further have at least one portion selected from a finger pocket portion 22 that extends from one end of the pouch portion 21 to cover the wearer's fingers and a hem portion 23 that extends from the other end of the pouch portion 21 to cover the wearer's wrist, and it is preferable to have both portions as illustrated in Figures 1A and 1B. The finger pocket portion 22 may have at least one portion selected from, for example, a first finger pocket portion 221 that covers the wearer's first finger (thumb), a second finger pocket portion 222 that covers the wearer's second finger (index finger), a third finger pocket portion 223 that covers the wearer's third finger (middle finger), a fourth finger pocket portion 224 that covers the wearer's fourth finger (ring finger), and a fifth finger pocket portion 225 that covers the wearer's fifth finger, depending on the wearer's needs. It is preferable to have first to fifth finger portions (221 to 225) as illustrated in Figures 1A and 1B. It is preferable that each of the first to fifth finger portions (221 to 225) is formed in a cylindrical shape with a closed portion that covers the wearer's fingertip, as illustrated in Figures 1A and 1B.

[0015] Figure 2 illustrates a cross-section in the thickness direction of the laminated structure Lh in a portion of the glove 10 where the laminated structure (hereinafter also referred to as "laminated structure Lh") is formed, with the glove body 20, at least one acrylic resin layer 30, and a polyvinyl chloride resin layer 40 arranged in order from the inside to the outside of the glove 10. As shown in Figure 2, the glove body 20 is made up of a plurality of threads 26. The inner surface side 24 of the glove body 20 is the side with the inner surface that comes into contact with the wearer's hand when the glove 10 is worn. The outer surface side 25 of the glove body 20 is the opposite side of the inner surface side 24 in the thickness direction of the glove body 20. The outer surface side 25 of the glove body 20 illustrated in Figure 2 is covered with at least one acrylic resin layer 30.

[0016] The glove body 20 is composed of multiple threads 26. In other words, each of the main pocket portion 21, finger pocket portion 22, and hem portion 23 of the glove body 20 shown in Figures 1A and 1B may be composed of at least one piece of fabric made of multiple threads 26. The glove body 20 may also be formed by sewing together the pieces of fabric that make up each of the main pocket portion 21, finger pocket portion 22, and hem portion 23 to form the glove body 20. The at least one piece of fabric may be selected from one woven fabric, multiple woven fabrics, one knitted fabric, and multiple knitted fabrics. The glove body 20 is preferably a knitted glove made of multiple threads 26. For example, the glove body 20 is preferably seamlessly knitted so that the multiple threads 26 form the glove body 20 as a knitted glove. In other words, it can also be said that the glove body 20 is preferably a knitted glove made of only one piece of knitted fabric made of multiple threads 26.

[0017] As illustrated in Figure 2, each thread 261 included in the plurality of threads 26 constituting the glove body 20 contains at least one fiber 265. The at least one fiber 265 may be a single fiber, but it is preferable that it be a plurality of fibers. In other words, each thread 261 may be a thread made of a single fiber, but it is preferable that it is a thread made of a plurality of fibers. Each thread 261 is not particularly limited as long as it is a thread that can be conventionally used in the technical field of knitted gloves, for example, spun yarn, monofilament yarn or multifilament yarn. Each thread 261 may be in the form of a single thread, or it may form a double thread 262 by twisting two threads 261 together, or it may form a double thread 263 by twisting two double threads 262 together.

[0018] The fineness of each individual yarn 261 is not particularly limited, as long as it is within the range of fineness values ​​that are possible for individual yarns conventionally used in the field of knitted gloves. From the viewpoint of avoiding breakage during knitting of the glove due to breakage of the yarn 261 and tearing when using the glove 10, the fineness of each individual yarn 261 may be, for example, 10 dtex or more, 25 dtex or more, preferably 40 dtex or more, and more preferably 50 dtex or more. From the viewpoint of providing flexibility to the glove body 20, the fineness of each individual yarn 261 may be, for example, 1,000 dtex or less, 700 dtex or less, preferably 600 dtex or less, and more preferably 550 dtex or less. The fineness values ​​described herein are calculated by winding 100 m of the sample yarn using a known measuring machine, measuring its mass, and multiplying the resulting mass by 100 to obtain the mass per 10,000 m (i.e., fineness (dtex)). In this specification, "total fineness" refers to the fineness of yarn made by twisting multiple threads together.

[0019] When the glove body 20 is composed of at least one knitted fabric, the density of the at least one knitted fabric is not particularly limited, as long as it is within the range of possible densities for conventional knitted gloves. In this case, from the viewpoint of allowing the wearer to easily obtain a tactile sensation derived from the fibers 265 on the inner surface 24 of the glove body 20, the density of the knitted fabric in the glove body 20 is such that the number of stitches per 1.0 inch (2.54 cm) in the course direction of the knitted fabric is, for example, 7 or more, preferably 8 or more. Furthermore, from the viewpoint of obtaining flexibility for the glove body 20, the density of the knitted fabric in the glove body 20 is such that the number of stitches per 1.0 inch (2.54 cm) in the course direction of the knitted fabric is such that it is, for example, 18 or less, preferably 15 or less. Note that the value of the knitted fabric density in this specification is the value obtained by measuring the number of stitches from the appearance of the knitted fabric portion that constitutes the central part of the palm 211. The course direction is the weft (horizontal) direction of the knitted fabric.

[0020] When the glove body 20 is composed of at least one knitted fabric, the gauge number of the knitting machine used to knit the at least one knitted fabric is not particularly limited, as long as it is a gauge number that is possible when manufacturing conventional knitted gloves in the field of knitted glove technology. In this case, from the viewpoint of making it easy for the wearer to obtain a tactile sensation derived from the fibers 265 on the inner surface 24 of the glove body 20, the at least one knitted fabric may be knitted on a knitting machine with a gauge of 10 or higher, and preferably on a knitting machine with a gauge of 13 or higher. Also, from the viewpoint of obtaining flexibility for the glove body 20, the at least one knitted fabric may be knitted on a knitting machine with a gauge of 21 or lower, and preferably on a knitting machine with a gauge of 18 or lower.

[0021] The at least one fiber 265 contained in each yarn 261 is not particularly limited, as long as it is a fiber that can be conventionally used for the manufacture of knitted gloves. Examples of the at least one fiber 265 include natural fibers, synthetic fibers, or inorganic fibers. Examples of natural fibers include cotton fibers or hemp fibers. Examples of synthetic fibers include polyester fibers, nylon fibers, aramid fibers, poly(p-phenylenebenzoxazole) (PBO) fibers, polyethylene fibers, polypropylene fibers, or polyacrylonitrile fibers. Polyester fibers are fibers composed of condensation polymers synthesized by dehydrating and condensing a polycarboxylic acid and a polyalcohol to form an ester bond, and examples include polyethylene terephthalate (PET) fibers, polytrimethylene terephthalate (PTT) fibers, or polybutylene terephthalate (PBT) fibers. The polyester fiber may also be, for example, a crystalline polyester fiber. Examples of aramid fibers include para-aramid fibers or meta-aramid fibers. Polyethylene fibers may be, for example, ultra-high molecular weight polyethylene fibers or highly stretchable polyethylene fibers. Examples of inorganic fibers include metal fibers. At least one fiber 265 may be a plurality of synthetic fibers in which inorganic particles are dispersed in a synthetic resin in each fiber. At least one fiber 265 may be a plurality of fibers in which at least one conductive fiber is included, and each yarn 261 may be a yarn made of these plurality of fibers. At least one fiber 265 may be a single fiber or a plurality of fibers made of only one type of fiber from the plurality of fibers exemplified here, or a plurality of fibers containing two or more types may be used.

[0022] The glove body 20 may contain at least one water repellent selected from silicone-based water repellents, acrylic-based water repellents, and urethane-based water repellents. However, since fluorine-based water and oil repellents may accumulate in the bodies of living organisms and may cause environmental pollution, it is preferable that the glove body 20 does not contain fluorine-based water and oil repellents.

[0023] The thickness of the glove body 20, that is, the length between the inner surface on the inner side 24 and the outer surface on the outer side 25 in the thickness direction of the glove body 20, may be, for example, 0.20 mm or more and 1.5 mm or less, and preferably 0.50 mm or more and 1.3 mm or less. In this specification, the value of "thickness" of the glove body 20 is the arithmetic mean of the thickness measurements obtained by cutting the glove 10 in the thickness direction, obtaining multiple microscope images of the cut surface of the glove 10 magnified 100 times using a digital microscope (Keyence Corporation, model: VHX-8000), measuring the length in the thickness direction of the layer to be measured (e.g., the glove body 20) at each of the 10 locations arbitrarily selected from the obtained multiple microscope images, and obtaining the thickness measurement value at the 10 locations.

[0024] The at least one acrylic resin layer 30 is a resin coating layer formed on at least a portion of the outer surface 25 of the glove body 20. From the viewpoint of excellent flexibility and adhesion, the at least one acrylic resin layer 30 is preferably a resin coating layer formed by solidifying and drying an acrylic resin latex, which will be described later. The portion of the outer surface 25 of the glove body 20 on which the at least one acrylic resin layer 30 is formed can be appropriately selected according to the intended use of the glove 10. For example, the at least one acrylic resin layer 30 may be formed over the entire outer surface 25 (outer surface) of the glove body 20. The at least one acrylic resin layer 30 may be formed over the entire palm side of the outer surface 25 (outer surface) of the glove body 20. The at least one acrylic resin layer 30 may be formed over the entire outer surface 25 (outer surface) of at least one portion of the glove body 20 selected from the main pocket portion 21, the finger pocket portion 22, and the hem portion 23. At least one acrylic resin layer 30 may be formed on a part of the palm portion 211 and the finger pocket portion 22, or it may be formed over the entire area of ​​the main pocket portion 21 and the finger pocket portion 22 and on at least a part of the hem portion 23, as illustrated in Figures 1A and 1B.

[0025] The thickness of at least one acrylic resin layer 30 is not particularly limited as long as it does not contradict the purpose of the present invention. The thickness of at least one acrylic resin layer 30 may be, for example, 0.08 mm or more and 0.80 mm or less, and preferably 0.10 mm or more and 0.50 mm or less. The thickness of at least one acrylic resin layer 30 is the thickness of only that single resin layer if the at least one acrylic resin layer 30 consists of only one resin layer. The thickness of at least one acrylic resin layer 30 is the total thickness of the two or more resin layers if the at least one acrylic resin layer 30 consists of two or more resin layers. Hereinafter, the method for measuring the "thickness" value of each resin layer in this specification is the same as the method for measuring the thickness of the glove body 20 described above, and the same explanation will not be repeated.

[0026] At least one acrylic resin layer 30 is composed of an acrylic resin composition containing a (meth)acrylic resin. In this specification, "(meth)acrylic" means either or both acrylic and methacrylic. The (meth)acrylic resin may be, for example, a homopolymer or copolymer of at least one (meth)acrylic monomer selected from the group consisting of (meth)acrylic acid, (meth)acrylonitrile, (meth)acrylic acid esters and (meth)acrylamides.

[0027] As (meth)acrylic acid, either acrylic acid or methacrylic acid, or both, can be used. As (meth)acrylonitrile, either acrylonitrile or methacrylonitrile, or both, can be used. As (meth)acrylamides, either (meth)acrylamide or N-substituted (meth)acrylamide, or both, can be used. As N-substituted (meth)acrylamide, for example, at least one compound selected from N-methyl(meth)acrylamide, N-ethyl(meth)acrylamide, N,N-dimethyl(meth)acrylamide, N,N-diethyl(meth)acrylamide, N-isopropyl(meth)acrylamide, and N-t-octyl(meth)acrylamide can be used.

[0028] As the (meth)acrylic acid ester, at least one compound selected from alkyl (meth)acrylate esters, (meth)acrylic acid monomers having a cycloalkyl group in the molecule, and alkoxyalkyl (meth)acrylate esters can be used. As the alkyl (meth)acrylic acid ester, for example, at least one compound selected from methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, phenoxyethyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, cyclohexyl (meth)acrylate, benzyl (meth)acrylate, lauryl (meth)acrylate, stearyl (meth)acrylate, and hydroxyethyl (meth)acrylate can be used. As the (meth)acrylic acid monomer having a cycloalkyl group in the molecule, at least one compound selected from cyclohexyl (meth)acrylate and isobornyl (meth)acrylate can be used. As the (meth)acrylate alkoxyalkyl ester, at least one compound selected from (meth)acrylate-2-methoxyethyl, (meth)acrylate-2-ethoxyethyl, and (meth)acrylate-2-butoxyethyl can be used.

[0029] The (meth)acrylic resin may be a polymer compound that contains in its molecule a constituent unit derived from another monomer that does not fall under the category of at least one (meth)acrylic monomer. As the other monomer, for example, at least one vinyl monomer that does not fall under the category of (meth)acrylic monomer can be used, selected from the group consisting of vinyl acetate, vinyl propionate, vinyl versatate, methyl vinyl ether, ethyl vinyl ether, propyl vinyl ether, butyl vinyl ether, styrene, α-methylstyrene, divinylstyrene, isoprene, chloroprene, butadiene, ethylene, tetrafluoroethylene, vinylidene fluoride, and N-vinylpyrrolidone. In the case of a (meth)acrylic resin that contains such constituent units derived from another monomer in its molecule, the proportion of the constituent unit derived from the at least one (meth)acrylic monomer in the molecule is higher than 50% by mass, for example, it may be 60% by mass or more, 70% by mass or more, 80% by mass or more, and preferably 90% by mass or more.

[0030] Acrylic resin readily adheres to polyvinyl chloride resin and adheres more readily to the glove body 20 than polyvinyl chloride resin. Therefore, by having at least one acrylic resin layer 30 interposed between the glove body 20 and the polyvinyl chloride resin layer 40 described later in the glove 10, the polyvinyl chloride resin layer 40 is less likely to peel off from the glove 10, and the polyvinyl chloride resin can be sealed to prevent it from penetrating to the inner surface on the inner side 24 of the glove body 20.

[0031] In order to provide the glove 10 with excellent flexibility and pliability, the acrylic resin in at least one acrylic resin layer 30 is preferably an acrylic copolymer having a glass transition temperature (Tg) of -50°C or higher and -20°C or lower. The higher the glass transition temperature of the acrylic resin, exceeding -20°C, the more the flexibility and pliability may be impaired. In this specification, "glass transition temperature" refers to the "intermediate glass transition temperature" measured by the method described in JIS K 7121-1987 "Method for measuring the transition temperature of plastics" and JIS K 7121:2012 "Method for measuring the transition temperature of plastics (Supplement 1)". The method for measuring the glass transition temperature in this specification is as follows: The sample is filled to the bottom of an aluminum measuring container for differential scanning calorimetry with 5.5 ± 0.5 mg of the sample so that there are no gaps. An aluminum lid is placed over the aluminum container filled with the sample to make a test specimen. The test specimen is placed in a Hitachi High-Tech Science Corporation "DSC7000X, AS-3" differential scanning calorimeter for measurement. First, under conditions of a nitrogen gas flow rate of 20 mL / min, the temperature is raised from 30°C to 200°C at a rate of 20°C / min. After holding for 10 minutes, the test specimen is quickly removed and allowed to cool in an environment of 25 ± 10°C. Next, the cooled test specimen is raised from 30°C to 200°C at a rate of 20°C / min to obtain a DSC curve. From this DSC curve, the midpoint glass transition temperature is calculated using the analysis software included with the instrument. Alumina is used as the reference material. The midpoint glass transition temperature is determined according to the JIS K 7121-1987 standard "9.3 Method for determining glass transition temperature".

[0032] The acrylic resin composition constituting at least one acrylic resin layer 30 may, for example, be a composition containing only a (meth)acrylic resin as a resin component. On the other hand, polyvinyl chloride resin adheres more easily to the polyvinyl chloride resin layer 40 than (meth)acrylic resin. Therefore, from the viewpoint of making the polyvinyl chloride resin layer 40 even less likely to peel off from the glove 10, it is preferable that the acrylic resin composition constituting at least one acrylic resin layer 30 is a composition containing both a (meth)acrylic resin and a polyvinyl chloride resin as resin components. The polyvinyl chloride resin is a resin containing more than 50% by mass of constituent units derived from vinyl chloride monomer, and may be, for example, polyvinyl chloride, or a copolymer of vinyl chloride monomer and vinyl acetate monomer. At least one resin component selected from the acrylic resin and polyvinyl chloride resin contained in the acrylic resin composition may be crosslinked with a crosslinking agent.

[0033] In this specification, the ratio of the polyvinyl chloride resin content to the total content of (meth)acrylic resin and polyvinyl chloride resin in an acrylic resin composition constituting at least one acrylic resin layer 30 (polyvinyl chloride resin content / (total content of (meth)acrylic resin and polyvinyl chloride resin)) is hereinafter also referred to as "ratio Rc". The larger the ratio Rc, the less likely the polyvinyl chloride resin layer 40 is to peel off from the glove 10. Also, the smaller the ratio Rc, the less likely the polyvinyl chloride resin is to penetrate the glove body 20 in the thickness direction from the outer surface 25 to the inner surface 24. For these reasons, the ratio Rc may be, for example, 0.05 or more and 0.90 or less, and preferably 0.10 or more and 0.90 or less. In this specification, "content" means the "total content" of multiple components when there are multiple components for which the content value is indicated.

[0034] The acrylic resin composition comprising at least one acrylic resin layer 30 may contain, in addition to the resin components described above, at least one additive selected from, for example, crosslinking agents, stabilizers, surfactants, thickeners, antioxidants, plasticizers, and film-forming aids. Examples of crosslinking agents include zinc oxide, polyfunctional epoxy compounds, polycarbodiimide compounds, or isocyanate compounds. In the acrylic resin composition, when the acrylic resin content is 100 parts by mass, the content of at least one additive (for example, the content of a plasticizer) may be, for example, 20 parts by mass or less, 10 parts by mass or less, 5 parts by mass or less, or 2 parts by mass or less.

[0035] Examples of plasticizers include diisononylcyclohexane-1,2-dicarboxylate, diisononyl phthalate (hereinafter also referred to as "DINP"), diisodecyl phthalate, diundecyl phthalate, phenyl alkyl sulfonate, bis-2-ethylhexyl terephthalate, glycol benzoate, dibutyl sebacate, bis-2-ethylhexyl sebacate), bis-2-ethylhexyl adipate, diisononyl adipate, phenyl alkyl sulfonate, di-n-alkyl adipate, and adipic acid. Diisodecyl, bis-2-butoxyethyl adipate, adipic acid polyesters with a molecular weight of 300 to 3,000, tributyl acetylcitrate, tris-2-ethylhexyl trimellitate, tributyl trimellitate, mixtures of linear alkyl esters of trimellitate, bis-2-ethylhexyl dodecanediate, tetra-2-ethylhexyl pyromellitate, mixtures of linear alkyl esters of pyromellitate, epoxidized soybean oil, epoxidized linseed oil, or epoxidized fatty acid octyl esters can be used. As plasticizers, the compounds or mixtures exemplified herein are not the only ones that may be used; other suitable compounds may be used alone or in combination of two or more.

[0036] The acrylic resin layer 30, which is at least one layer, may be just one layer of acrylic resin. The acrylic resin composition constituting the one layer may, for example, contain only acrylic resin as a resin component, and preferably contains acrylic resin and polyvinyl chloride resin as resin components. The ratio Rc in the acrylic resin composition constituting the one layer of acrylic resin may be, for example, 0.90 or less, 0.05 to 0.90, preferably 0.10 to 0.50, and more preferably 0.10 to 0.30.

[0037] Alternatively, at least one acrylic resin layer 30 may have a laminated structure (hereinafter also referred to as "laminated structure La") that includes two or more acrylic resin layers. The laminated structure La can also be said to be at least one acrylic resin layer 30 (two or more acrylic resin layers) portion of the laminated structure Lh. From the viewpoint of further improving the adhesion between the laminated structure La and the glove body 20, it is preferable that the proportion Rc in the acrylic resin composition constituting the acrylic resin layer is smaller the closer the acrylic resin layer is to the glove body 20 in the laminated structure La. In other words, since acrylic resin adheres more easily to the glove body 20 than polyvinyl chloride resin, the smaller the proportion Rc, the higher the adhesion between the laminated structure La and the glove body. Furthermore, from the viewpoint of further improving the adhesion between the laminated structure La and the polyvinyl chloride resin layer 40, it is preferable that the plasticizer content in the acrylic resin composition constituting the acrylic resin layer is lower, when the polyvinyl chloride resin content is 100 parts by mass, as the acrylic resin layer is located closer to the glove body 20 in the laminated structure La. In other words, the lower the plasticizer content in the acrylic resin composition in the laminated structure La, the easier it is for the plasticizer contained in the polyvinyl chloride resin layer 40 to migrate to the laminated structure La due to the concentration gradient, which has the advantage of further improving the adhesion between the laminated structure La and the polyvinyl chloride resin layer 40. In addition, if the plasticizer content in the acrylic resin composition is not too high, there is also the advantage that the flexibility of the glove 10 is not easily impaired, which will be described in more detail later.

[0038] Figures 1A, 1B, and 2 show a case where the laminated structure La of at least one acrylic resin layer 30 includes a first acrylic resin layer 301 formed on at least a portion of the outer surface 25 (outer surface) of the glove body 20, and a second acrylic resin layer 302 formed on at least a portion of the outer surface 31 of the first acrylic resin layer 301. The second acrylic resin layer 302 may be formed on a portion of the outer surface 31 of the first acrylic resin layer 301, or it may be formed over the entire outer surface 31. Figures 1A and 1B illustrate a case where the second acrylic resin layer 302 is formed so as to cover the entire main pouch portion 21 and finger pocket portion 22 and a portion of the hem portion 23, with the first acrylic resin layer 301 interposed between it and the glove body 20.

[0039] It is preferable that the proportion Rc in the acrylic resin composition constituting the first acrylic resin layer 301 is smaller than the proportion Rc in the acrylic resin composition constituting the second acrylic resin layer 302. Here, the difference between the proportion Rc in the acrylic resin composition constituting the second acrylic resin layer 302 and the proportion Rc in the acrylic resin composition constituting the first acrylic resin layer 301 may be, for example, 0.05 or more and 0.90 or less, preferably 0.30 or more and 0.85 or less, and more preferably 0.40 or more and 0.80 or less.

[0040] The ratio Rc in the first acrylic resin layer 301 may be, for example, 0.60 or less, preferably 0.05 to 0.50, and more preferably 0.10 to 0.30.

[0041] The ratio Rc in the second acrylic resin layer 302 may be, for example, 0.10 or more and 0.98 or less, 0.30 or more and 0.97 or less, 0.50 or more and 0.96 or less, preferably 0.80 or more and 0.95 or less, more preferably 0.85 or more and 0.94 or less, and even more preferably 0.90 or more and 0.93 or less.

[0042] The polyvinyl chloride resin layer 40 is a resin coating layer formed on at least a part of the outer surface 32 of at least one acrylic resin layer 30. The polyvinyl chloride resin layer 40 may be formed continuously or intermittently on a part of the outer surface 32 of at least one acrylic resin layer 30, or may be formed over the entire outer surface 32. In FIGS. 1A and 1B, an example is illustrated in which the polyvinyl chloride resin layer 40 is the outermost layer and covers the entire main bag portion 21 and finger bag portions 22 in a state where at least one acrylic resin layer 30 (the first acrylic resin layer 301 and the second acrylic resin layer 302) is interposed between the polyvinyl chloride resin layer 40 and the glove body 20. Thus, the polyvinyl chloride resin layer 40 is the outermost layer arranged on the opposite side of the glove body 20 in the thickness direction of the glove 10 (that is, the outermost layer of the glove 10), and it is preferable that the entire outer surface 41 of the polyvinyl chloride resin layer 40 is an exposed surface.

[0043] Alternatively, for example, although not shown, at least one other polyvinyl chloride resin layer may be formed on at least a part of the outer surface 41 of the polyvinyl chloride resin layer 40. The at least one other polyvinyl chloride resin layer may be one other polyvinyl chloride resin layer, or may be two or more other polyvinyl chloride resin layers. The resin composition constituting the at least one other polyvinyl chloride resin layer may be, for example, the same as or approximate to the polyvinyl chloride resin composition constituting the polyvinyl chloride resin layer 40. When the at least one other polyvinyl chloride resin layer is formed, the outermost layer among the at least one other polyvinyl chloride resin layers becomes the outermost layer of the glove 10. The outermost layer in this case may contain a plurality of particles for anti-slip. A part of the plurality of particles may be exposed on the outer surface of the outermost layer of the glove 10, and the remaining part may be embedded in the outermost layer.

[0044] The polyvinyl chloride resin composition constituting the polyvinyl chloride resin layer 40 is a composition containing polyvinyl chloride resin as a resin component. This polyvinyl chloride resin composition may contain other resins that are not polyvinyl chloride resins as resin components, as long as it is in trace amounts that do not contradict the purpose of the present invention. For example, the ratio of the content of other resins to the content of polyvinyl chloride resin and other resins (content of other resins / content of polyvinyl chloride resin and other resins) may be 0.99 or more. It is preferable that the polyvinyl chloride resin composition constituting the polyvinyl chloride resin layer 40 contains only the aforementioned polyvinyl chloride resin as a resin component.

[0045] The polyvinyl chloride resin composition constituting the polyvinyl chloride resin layer 40 is preferably obtained by heat-drying a polyvinyl chloride resin composition for paste. The polyvinyl chloride resin composition for paste can also be called a resin paste containing polyvinyl chloride resin. In other words, the polyvinyl chloride resin layer 40 is preferably a resin layer obtained by heat-drying a resin paste containing polyvinyl chloride resin. Alternatively, in other words, the polyvinyl chloride resin composition constituting the polyvinyl chloride resin layer 40 is preferably a composition containing polyvinyl chloride resin and the aforementioned plasticizer. In the polyvinyl chloride resin composition, when the polyvinyl chloride resin content is 100 parts by mass, the content of the aforementioned plasticizer may be, for example, 10 parts by mass or more and 200 parts by mass or less, 30 parts by mass or more and 180 parts by mass or less, 50 parts by mass or more and 150 parts by mass or less, preferably 80 parts by mass or more and 140 parts by mass or less, and more preferably 100 parts by mass or more and 120 parts by mass or less.

[0046] The polyvinyl chloride resin composition constituting the polyvinyl chloride resin layer 40 may further contain, in addition to the polyvinyl chloride resin and plasticizer, at least one additive selected from stabilizers, defoamers, solvents, and pigments. The content of at least one additive in the polyvinyl chloride resin composition may be, for example, 10 parts by mass or less, or 5 parts by mass or less, when the content of the polyvinyl chloride resin is 100 parts by mass.

[0047] The thickness of the polyvinyl chloride resin layer 40 is not particularly limited as long as it does not go against the object of the present invention. From the viewpoint of not significantly impairing the flexibility of the glove 10 and imparting a certain degree of water resistance, acid resistance, alkali resistance, solvent resistance, etc. to the glove 10, the thickness of the polyvinyl chloride resin layer 40 may be, for example, 0.1 mm or more and 2.0 mm or less, preferably 0.2 mm or more and 1.5 mm or less. Further, when measuring the thickness of the polyvinyl chloride resin layer 40 by the method for measuring the thickness of the resin layer described above, the difference between the maximum value and the minimum value of the thickness in the polyvinyl chloride resin layer 40 may be, for example, within 0.5 mm, preferably within 0.2 mm.

[0048] In the glove 10, the peel strength when peeling the polyvinyl chloride resin layer 40 from at least one layer of the acrylic resin layer 30 may be, for example, 15 N or more, 20 N or more, preferably 25 N or more, more preferably 35 N or more, and even more preferably 50 N or more. This peel strength is not particularly limited in terms of the upper limit value, but it is generally 100 N or less.

[0049] The value of "peel strength" in this specification is the value measured by the measurement method described below. The measurement method described below conforms to JIS K 6256-1:2013 "Vulcanized rubber and thermoplastic rubber - Method for determining adhesion - Part 1: Peel strength to cloth", however, the size of the test piece, the length to be peeled of the polyvinyl chloride resin layer 40 of the test piece, the distance between chucks, and the travel distance have been changed from the method described in JIS K 6256-1:2013. In the method for measuring peel strength, first, a test piece measuring 10 mm in width and 60 mm in length is cut from the glove 10. On this test piece, the polyvinyl chloride resin layer 40 is peeled off for a length of 10 mm at the outer surface 32 of the acrylic resin layer (for example, the second acrylic resin layer 302) that is in contact with the polyvinyl chloride resin layer 40 (i.e., the interface between at least one acrylic resin layer 30 and the polyvinyl chloride resin layer 40) to form a gripping portion. In a tensile testing machine (Shimadzu Corporation, model: AGS-500NX), the distance between the chucks (distance between the two chucks) is set to 10 mm. One chuck is fitted with the portion of the polyvinyl chloride resin layer 40 at one end of the test specimen that has been peeled from at least one acrylic resin layer 30 (one gripping part), and the other chuck is fitted with the portion of the test specimen at the other end that includes at least one acrylic resin layer 30 (the other gripping part). A 180° peel test is performed on this tensile testing machine under the conditions of a tensile speed of 50 mm / min and a travel distance of 50 mm. In the 180° peel test, a 50 mm portion of the 60 mm long test specimen is peeled, excluding the 10 mm portion that has been peeled beforehand. The tensile testing machine plots multiple peaks on a graph representing the magnitude of the load required for 180° peeling. The arithmetic mean of the heights (magnitude of load) of each of these multiple peaks is taken as the peel strength value (unit: N).

[0050] It is preferable that polyvinyl chloride resin is not detected on the inner surface 24 of the glove body 20 of the glove 10, that is, the inner surface that comes into contact with the wearer when the glove 10 is worn, even when analyzed by the Fourier transform infrared spectroscopy (FT-IR) method described below. In the FT-IR method, a section of the glove is used as a test specimen, and the inner surface of this test specimen (the surface that comes into contact with the wearer's hand) is the measurement target. From this measurement target, 256 cumulative measurements of 500 to 3500 cm³ are taken using FT-IR. －１ Spectral data within a specified range is obtained. For comparison, nitrile rubber (NBR) coatings, natural rubber (NR) coatings, acrylic polymer coatings, polyurethane coatings, and polyvinyl chloride coatings are prepared in separate petri dishes and similarly subjected to FT-IR measurements to obtain spectral data for each resin coating. By comparing these comparison spectral data, a peak specific to the polyvinyl chloride coating (i.e., a peak detected in the polyvinyl chloride coating but not in the other comparison coatings) is detected. The spectral data of the sample being measured is then examined to see if this specific peak is included. If the specific peak is not included, it is determined that polyvinyl chloride resin is not detected in the sample being measured (the inner surface of the glove).

[0051] As shown in Figure 3, a glove manufacturing method S50 according to one embodiment is a method capable of manufacturing the gloves 10 described above, and may include a raw material preparation step S51, a pretreatment step S52, a step of forming at least one acrylic resin layer S53, and a step of forming a polyvinyl chloride resin layer S54.

[0052] In the raw material preparation step S51, the raw materials required for the manufacture of the glove 10 are prepared. For example, a base glove (a glove body before the resin layer is applied) that will be used as the material for the glove body 20 is prepared. For this purpose, a commercially available base glove may be obtained, a commercially available knitted glove may be obtained as the base glove, a base glove may be formed by sewing together multiple pieces of fabric, or a knitted glove may be knitted from multiple threads using a glove knitting machine. The composition of the base glove is the same as that of the glove body 20 described above, except that the resin layer has not yet been applied, so the same explanation will not be repeated. For example, the composition of the multiple threads that make up the base glove, each thread, and at least one fiber is the same as that of the multiple threads 26, each thread 261, and at least one fiber 265 described above. In addition, in the raw material preparation step S51, a coagulant solution, acrylic resin latex, and a polyvinyl chloride resin composition for paste, which will be described later, may also be prepared.

[0053] In the pretreatment step S52, from the viewpoint of efficiently forming an acrylic resin layer later, a coagulant solution may be applied to at least a portion of the outer surface of the original hand by a known method and dried. Examples of coagulants include inorganic salts or acids that have the effect of coagulating (meth)acrylic resins. Examples of inorganic salts include calcium nitrate, calcium chloride, or magnesium sulfate. Examples of acids include acetic acid or citric acid. In the pretreatment step S52, it is preferable to immerse at least a portion of the outer surface of the original hand in the coagulant solution, and then remove the original hand from the coagulant solution and dry it. For example, the original hand may be placed over a hand mold, the original hand and hand mold may be immersed together in the coagulant solution, and then the original hand and hand mold may be removed from the coagulant solution and dried. The drying method is not particularly limited, and for example, it may be air-dried at room temperature (5°C to 35°C). The material of the hand mold may be, for example, ceramic, iron, or aluminum. The hand mold may be coated with, for example, fluororesin or silicone resin. The hand shape is a three-dimensional reproduction of a human hand, and the number of fingers, finger length, thickness, palm circumference, wrist circumference, and other details can be arbitrarily determined.

[0054] In the pretreatment step S52, instead of applying a coagulant to the raw glove, a water-repellent agent may be applied to the raw glove. Note that the use of a water-repellent agent is optional in the manufacture of the glove 10, and it is not necessary to apply a water-repellent agent to the raw glove. As the water-repellent agent, silicone-based water-repellent agents, acrylic-based water-repellent agents, or urethane-based water-repellent agents can be used. If a water-repellent agent is added to the raw glove in the pretreatment step S52, the raw glove coated with the water-repellent agent may be dried, for example, in an atmosphere between 80°C and 170°C.

[0055] In the step S53 for forming at least one acrylic resin layer, at least a portion of the outer surface of the original hand is immersed in an acrylic resin latex emulsion containing (meth)acrylic resin, and then the original hand is removed from the acrylic resin latex and dried to form at least one acrylic resin layer 30 on at least a portion of the outer surface of the original hand. This process is efficient and preferable when performed with the original hand placed over the aforementioned hand mold. The number of times this process is performed depends on how many acrylic resin layers are to be formed as at least one acrylic resin layer 30. For example, if it is sufficient to form only one acrylic resin layer, this process only needs to be performed once. Alternatively, as illustrated in Figures 1A, 1B, and 2, if a first acrylic resin layer 301 and a second acrylic resin layer 302 are to be formed as at least one acrylic resin layer 30, this process will be performed twice, and acrylic resin latex with different compositions will be used for each process. Therefore, Figure 3 illustrates a case in which the acrylic resin layer formation step S53 includes at least one acrylic resin layer formation step S531 and a second acrylic resin layer formation step S532.

[0056] Acrylic resin latex can also be described as a resin emulsion that serves as a raw material for an acrylic resin composition constituting at least one acrylic resin layer 30. The dispersion medium for the resin components in acrylic resin latex is a hydrophilic solvent, preferably water. The resin components, at least one additive (e.g., a plasticizer), and the proportion Rc in acrylic resin latex are as described above in the description of the acrylic resin composition, and the same description will not be repeated. Acrylic resin latex containing (meth)acrylic resin and polyvinyl chloride resin may be prepared by mixing latex containing (meth)acrylic resin and latex containing polyvinyl chloride resin, and used in the at least one acrylic resin layer formation step S53. The solid content in acrylic resin latex, that is, the content of resin components, may be, for example, 3% by mass or more and 30% by mass or less. If the polyvinyl chloride resin contained in the acrylic resin latex has a degree of polymerization within a certain range, it is easily plasticized by a plasticizer, adheres well to the polyvinyl chloride resin layer 40, and facilitates the formation of at least one acrylic resin layer 30. From this viewpoint, the degree of polymerization of the polyvinyl chloride resin contained in the acrylic resin latex may be, for example, 600 to 1,300, preferably 650 to 1,000, and more preferably 680 to 800.

[0057] In this specification, the acrylic resin latex that serves as the raw material for the acrylic resin composition constituting the first acrylic resin layer 301 is also referred to as the "first acrylic resin latex" below. The type of resin component in the first acrylic resin latex, the degree of polymerization of the polyvinyl chloride resin, at least one additive, the ratio Rc and dispersion medium, and the method for carrying out the first acrylic resin layer formation step S531 are the same as those described above for the acrylic resin latex and the method for carrying out step S53, and the same explanation will not be repeated. The solid content in the first acrylic resin latex, that is, the resin component content, is preferably 20% by mass or more and 30% by mass or less, from the viewpoint of forming the first acrylic resin layer 301 having a thickness suitable for sealing the polyvinyl chloride resin without impairing the flexibility of the glove 10. The drying in step S531 may be carried out by drying the pulled-out glove for 5 minutes or more and 20 minutes or less in an atmosphere of 70°C or more and 90°C or less. In step S531, the raw material on which the first acrylic resin layer has been formed may be leached, for example, by immersing it in water at a temperature of 40°C to 60°C for 10 minutes to 40 minutes, thereby removing impurities from the first acrylic resin layer. The raw material after leaching may be dried, for example, in an atmosphere of 70°C to 90°C for 5 minutes to 20 minutes.

[0058] In this specification, the acrylic resin latex that serves as the raw material for the acrylic resin composition constituting the second acrylic resin layer 302 is also referred to as the "second acrylic resin latex" below. When performing the second acrylic resin layer formation step S532, at least a portion of the outer surface of the first acrylic resin layer formed on the raw material after step S531 described above is immersed in the second acrylic resin latex, and then the raw material to which the second acrylic resin latex adheres is pulled out and dried to form the second acrylic resin layer on at least a portion of the outer surface of the second acrylic resin layer. The dispersion medium for the resin component in the second acrylic resin latex is a hydrophilic solvent, preferably water. The resin component, at least one additive, and the proportion Rc in the second acrylic resin latex are as described above in the description of the first acrylic resin layer 301, and the same description will not be repeated. The solid content of the second acrylic resin latex, that is, the resin component content, is preferably 3% by mass or more and 10% by mass or less, from the viewpoint of easily adhering to the polyvinyl chloride resin layer 40 and easily forming a thin second acrylic resin layer 302. The second acrylic resin latex may contain less than 10 parts by mass of plasticizer when the polyvinyl chloride resin content is 100 parts by mass, or it may not contain any plasticizer. In the second acrylic resin latex containing polyvinyl chloride resin, the degree of polymerization of the contained polyvinyl chloride resin may be, for example, 600 to 1,300, preferably 650 to 1,000, and more preferably 680 to 800. Drying in this step S532 may be carried out by drying the pulled-out raw material for, for example, 20 minutes to 60 minutes in an atmosphere of 120°C to 140°C.

[0059] It is preferable that the proportion Rc in the first acrylic resin latex is smaller than the proportion Rc in the second acrylic resin latex.

[0060] In the polyvinyl chloride resin layer formation step S54, a polyvinyl chloride resin layer 40 is formed on at least a portion of the outer surface of the acrylic resin layer 30 formed on the original glove using a polyvinyl chloride resin paste composition (resin paste containing polyvinyl chloride resin). The polyvinyl chloride resin used in the polyvinyl chloride resin paste composition in the polyvinyl chloride resin layer formation step S54, the content of the plasticizer mentioned above when the polyvinyl chloride resin content is 100 parts by mass, and at least one additive and its content are as described in the description of the polyvinyl chloride resin constituting the polyvinyl chloride resin layer 40, and the same description will not be repeated.

[0061] In the polyvinyl chloride resin layer formation step S54, for example, a polyvinyl chloride resin composition for paste (resin paste containing polyvinyl chloride resin) may be applied to at least a portion of the outer surface of the at least one acrylic resin layer 30 formed on the original hand by a known coating method and then heat-dried to form a polyvinyl chloride resin layer 40 on at least a portion of the outer surface of the at least one acrylic resin layer 30 formed on the original hand, thereby obtaining the glove 10. Alternatively, in this step S54, it is preferable to immerse at least a portion of the outer surface of the at least one acrylic resin layer 30 formed on the original hand in the polyvinyl chloride resin composition for paste, remove it from the paste, and heat-dry it to obtain the glove 10 with the polyvinyl chloride resin layer 40 formed on it. It is preferable to perform this step S54 with the original hand placed over the aforementioned hand mold. As a method of heat drying, a glove 10 in which a polyvinyl chloride resin layer 40 is formed may be obtained by heat drying a raw hand, in which the paste-type polyvinyl chloride resin composition is attached to at least a portion of the outer surface of the polyvinyl chloride resin layer, in an atmosphere of 170°C to 210°C for 5 to 20 minutes. After this drying, the glove 10 may be cooled together with the hand mold, and then the glove 10 may be removed from the hand mold.

[0062] In the polyvinyl chloride resin layer formation step S54, when a coating method is performed, the thixotropy (T.I.) of the polyvinyl chloride resin composition for paste (resin paste containing polyvinyl chloride resin) at 35°C, measured by a B-type viscometer, is preferably 0.10 or more and 0.20 or less. Alternatively, when immersion is performed in this step S54, the thixotropy (T.I.) of the polyvinyl chloride resin composition for paste at 35°C, measured by a B-type viscometer, is preferably 0.15 or more and 0.30 or less. Furthermore, the viscosity (V6) of the polyvinyl chloride resin composition for paste at 35°C, measured by a B-type viscometer with a rotor speed of 6 rpm, is preferably 3,000 mPa·s or more and 15,000 mPa·s or less. When the polyvinyl chloride resin composition for paste has these thixotropy and viscosity properties, the polyvinyl chloride resin composition does not easily flow down when the raw hand to which the paste is attached is heated and dried. This makes it easier to form a polyvinyl chloride resin layer 40 that is substantially uniform in thickness in each part of the glove 10 and has very little variation in thickness.

[0063] The following are disclosed herein: (1) A glove comprising: a glove body composed of a plurality of threads, each thread containing at least one fiber; at least one acrylic resin layer formed on at least a portion of the outer surface of the glove body and composed of an acrylic resin composition containing a (meth)acrylic resin; and a polyvinyl chloride resin layer formed on at least a portion of the outer surface of the at least one acrylic resin layer and composed of a polyvinyl chloride resin composition containing a polyvinyl chloride resin.

(3) The glove according to (1) above, wherein the at least one acrylic resin layer is a two or more acrylic resin layer comprising a first acrylic resin layer formed on at least a part of the outer surface of the glove body and a second acrylic resin layer formed on at least a part of the outer surface of the first acrylic resin layer, and the ratio in the acrylic resin composition constituting the first acrylic resin layer (content of polyvinyl chloride resin / (total content of (meth)acrylic resin and polyvinyl chloride resin)) is smaller than the ratio in the acrylic resin composition constituting the second acrylic resin layer (content of polyvinyl chloride resin / (total content of (meth)acrylic resin and polyvinyl chloride resin)).

(6) The glove according to any one of (1) to (5) above, wherein the glass transition temperature of the (meth)acrylic resin is -50°C or higher and -20°C or lower. (7) The glove according to any one of (1) to (6) above, wherein the thickness of the polyvinyl chloride resin layer is 0.2 mm or higher and 1.5 mm or lower, and the difference between the maximum and minimum thickness of the polyvinyl chloride resin layer is 0.2 mm or less. (8) The glove according to any one of (1) to (7) above, wherein the peel strength when peeling the polyvinyl chloride resin layer from at least one acrylic resin layer is 20 N or higher. (9) The glove body is a knitted glove made of the plurality of threads, according to any one of (1) to (8) above.

[0064] The present invention is not limited to the embodiments described above, and can be implemented in various forms with improvements, modifications, or variations based on the knowledge of those skilled in the art, without departing from the spirit of the invention. The present invention may also be implemented in a form in which any specific feature is replaced with another technology, within the scope of producing the same function or effect.

[0065] The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

[0066] <Preparation of Raw Materials> A multifilament yarn was prepared by twisting together multiple polyester fibers and applying a woolly finish. The fineness of the single strand of this multifilament yarn was 83 dtex. These multifilament yarns were twisted together to obtain a double-ply yarn. By twisting together three of these double-ply yarns, a yarn with a total fineness of 500 dtex was obtained. Using multiple strands of this yarn (total fineness 500 dtex), a knitted glove was prototyped by seamlessly knitting it on a 13-gauge glove knitting machine (manufactured by Shima Seiki Mfg. Ltd., model: N-SFG-I). The thickness of the knitted glove prototyped in this way was measured using the thickness measurement method with the constant-pressure thickness measuring instrument described above, and was within the range of 1.0 mm to 1.1 mm. This knitted glove was used as the base glove (glove body) in the examples and comparative examples described later.

[0067] Furthermore, in the examples and comparative examples described later, the following materials were prepared as raw materials for the resin composition constituting the first acrylic resin layer and the resin composition constituting the second acrylic resin layer.

[0068] Furthermore, in the examples and comparative examples described later, the following were prepared as raw materials for the polyvinyl chloride resin composition (resin paste containing polyvinyl chloride resin) that constitutes the polyvinyl chloride resin layer: Polyvinyl chloride resin powder (manufactured by Kaneka Corporation, model number: PSM-30, 100% purity, used as a polyvinyl chloride resin component) DINP (manufactured by J-Plus Co., Ltd., diisononyl phthalate, 100% purity, used as a plasticizer) Stabilizer (manufactured by ADEKA Corporation, model number: SC-72) Thickener B (manufactured by Tokuyama Corporation, model number: QS-102)

[0069] <Example 1> In Example 1, the raw materials were mixed in the proportions shown in Table 1 to prepare the first acrylic resin latex. During this preparation, water and thickener A were mixed with the raw materials so that the total solids concentration was 25% by mass and the viscosity (V6) at 20°C, measured using a B-type viscometer with a rotor speed of 6 rpm, was 2,500 mPa·s.

[0073] In Example 1, a polyvinyl chloride resin paste was prepared by mixing the raw materials for a polyvinyl chloride resin paste (resin paste containing polyvinyl chloride resin) in the proportions shown in Table 3. The viscosity of the prepared polyvinyl chloride resin paste at 35°C, measured using a B-type viscometer according to the aforementioned measurement method, was 9,390 mPa·s for the viscosity (V6) at a rotor speed of 6 rpm and 5,900 mPa·s for the viscosity (V12) at a rotor speed of 12 rpm. The thixotropy (T.I., the value of Y / V9) of the prepared polyvinyl chloride resin paste at 35°C, measured using the aforementioned method, was 0.174 (V9 = 2410 mPa·s, Y = (V6 - V12) × 0.12 = 419, (T.I.) = Y / V9 = 0.174). As shown in Table 3, in Examples 2 to 5 and Comparative Examples 6 to 9 described later, the polyvinyl chloride resin paste prepared in Example 1 was used as is.

[0074]

[0075] In Example 1, as a pretreatment step, a coagulant solution was prepared by mixing 3 parts by mass of calcium chloride with 100 parts by mass of methanol. The prototype hand was then placed over a ceramic hand mold at 70°C. The prototype hand, along with the hand mold, was then immersed in the coagulant solution so that the entire area of ​​the finger pockets and main pocket on the outer surface of the prototype hand, and a portion of the bottom edge, were submerged. At this time, the hand mold was lowered at a speed of 10 mm / second to immerse the prototype hand in the coagulant solution. The hand mold was stopped descending and held for 1 second with the entire area of ​​the finger pockets and main pocket and a portion of the bottom edge submerged in the coagulant solution, and then the prototype hand was lifted out of the coagulant solution by raising the hand mold at a speed of 7 mm / second. The prototype hand, along with the hand mold, was allowed to air dry at room temperature for 10 seconds.

[0076] Next, in Example 1, as the first acrylic resin layer formation step, the original hand with the coagulant attached, along with the hand mold, was immersed in the first acrylic latex prepared according to the formulation in Table 1, so that the entire area of ​​the finger pockets and main pockets on the outer surface of the original hand, and a part of the bottom edge, were submerged. At this time, the hand mold was lowered at a speed of 10 mm / second to immerse the original hand in the first acrylic resin latex, and the lowering of the hand mold was stopped and held for 10 seconds with the entire area of ​​the finger pockets and main pockets and a part of the bottom edge submerged in the first acrylic resin latex. Then, the hand mold was raised at a speed of 7 mm / second to remove the original hand from the first acrylic resin latex. The original hand, removed from the first acrylic resin latex, along with the hand mold, was dried in an atmosphere of 80°C for 10 minutes to form the first acrylic resin layer on the outer surface of the entire area of ​​the finger pockets and main pockets and a part of the bottom edge of the original hand. The original hand, with the first acrylic resin layer formed on it, was immersed in water at 50°C for 20 minutes, along with the hand mold, to remove impurities from the first acrylic resin layer through leaching. After this leaching, the original hand, along with the hand mold, was dried again in an 80°C atmosphere for 10 minutes.

[0077] In Example 1, as a second acrylic resin layer formation step, the original hand with the first acrylic resin layer formed on it was immersed, along with the hand mold, in a second acrylic resin latex prepared according to the formulation in Table 2, so that the portion of the original hand that covers the entire finger pocket and main pocket area and a portion of the hem in the first acrylic resin layer was submerged. At this time, the hand mold was lowered at a speed of 10 mm / second to immerse the original hand in the second acrylic resin latex, and the descent of the hand mold was stopped and held for 10 seconds with the entire finger pocket and main pocket area and a portion of the hem submerged in the second acrylic resin latex. Then, the hand mold was raised at a speed of 7 mm / second to remove the original hand from the second acrylic resin latex. The original hand, lifted from the second acrylic resin latex, was dried in a 130°C atmosphere for 40 minutes, along with the hand mold, to form the second acrylic resin layer on the outer surface of the portion of the original hand that covers the entire finger pocket and main pocket area, as well as a part of the hem, in the first acrylic resin layer.

[0078] Subsequently, in Example 1, as a polyvinyl chloride resin layer formation step, the original hand with the second acrylic resin layer formed on it was immersed, along with the hand mold, in a polyvinyl chloride resin paste for paste prepared according to the formulation in Table 3 (resin paste containing polyvinyl chloride resin) so that the portion of the original hand covering the entire finger pocket and main pocket area in the second acrylic resin layer was submerged. At this time, the hand mold was lowered at a speed of 10 mm / second to immerse the original hand in the polyvinyl chloride resin paste for paste. The hand mold was stopped descending with the entire finger pocket and main pocket area submerged in the polyvinyl chloride resin paste for paste and held for 1 second, after which the original hand was lifted out of the polyvinyl chloride resin paste for paste by raising the hand mold at a speed of 5 mm / second. A prototype glove according to Example 1 was fabricated by taking a hand drawn from a polyvinyl chloride resin composition for paste, heating and drying it together with the hand mold at 190°C for 10 minutes, thereby forming a polyvinyl chloride resin layer on the outer surface of the portion of the hand that covers the entire finger pocket and main pocket area in the second acrylic resin layer. After cooling the glove together with the hand mold, the glove was removed from the hand mold to obtain the glove according to Example 1.

[0079] The gloves according to Example 1, which were prototyped under the conditions described above, had the appearance illustrated in Figures 1A and 1B. Furthermore, when the gloves according to Example 1 were analyzed using the aforementioned FT-IR method, no peaks specific to polyvinyl chloride were detected in the spectral data obtained from the inner surface on the inner side of the glove body. Therefore, it was suggested that the polyvinyl chloride resin did not penetrate to the inner surface of the glove body in the gloves according to Example 1.

[0080] <Examples 2 to 5> In each of Examples 2 to 5, a first acrylic resin latex with a modified formulation as shown in Table 1 and a second acrylic resin latex with a modified formulation as shown in Table 2 were prepared and used to prototype gloves. The other prototypes were manufactured under the same conditions as in Example 1, and gloves corresponding to each of Examples 2 to 5 were obtained. Furthermore, when the gloves according to each of Examples 2 to 5 were analyzed by the FT-IR method described above, no peaks specific to polyvinyl chloride were detected in the spectral data obtained from the inner surface on the inner side of the glove body. Therefore, it was suggested that the polyvinyl chloride resin did not penetrate to the inner surface of the glove body in each of Examples 2 to 5.

[0090]

[0091] <Comparative Examples 10 to 13> For each of Comparative Examples 10 to 13, the following gloves equipped with a vinyl chloride resin layer, already commercially available from Showa Glove Co., Ltd., were prepared. Note that each of the following Comparative Examples 10, 11, and 13 is a conventional glove equipped with a vinyl chloride resin layer, manufactured by applying a fluorine-based oil repellent to the base glove during the manufacturing process, followed by immersing the base glove in a vinyl chloride resin paste or applying a vinyl chloride resin paste to the base glove. Comparative Example 10: A work glove G comprising a glove body (innermost layer) and a vinyl chloride resin layer (outermost layer). Comparative Example 11: A work glove N comprising a glove body (innermost layer) and a vinyl chloride resin layer (outermost layer). Comparative Example 12: A single-layer glove T composed only of a vinyl chloride resin layer. Comparative Example 13: An oil-resistant glove V comprising a glove body (innermost layer) and three layers of vinyl chloride resin formed on the outside of the glove body.

[0092] The thickness of each resin layer was measured for the gloves according to Example 1 and each of Comparative Examples 10 to 13 using the constant-pressure thickness measuring instrument described above. The measurement results are shown in Table 6.
