Description

[Technical Field]

[0001] The present invention relates to an anti-slip glove. [Background technology]

[0002] Anti-slip gloves with a rubber or resin coating layer laminated on the outer surface of the knitted glove body are widely used for agricultural work, logistics work, etc. In such gloves, reinforcement is sometimes performed on areas that are particularly prone to wear, such as the fingertips and the crotch of the thumb. Known methods for such reinforcement include increasing the thickness of the coating layer (see JP 4-333604 A), increasing the strength of the fibers used in the relevant parts of the knitted glove body (see JP 2008-7900 A), and laminating a reinforcing patch on the outer surface of the coating layer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 4-333604 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-7900 Summary of the Invention [Problem to be solved by the invention]

[0004] Increasing the thickness of the coating layer makes the coating layer harder and less flexible, making it difficult to grip an object and resulting in insufficient cushioning and poor workability. Increasing the strength of the fibers in the knitted glove body makes the fibers exposed when the coating layer wears, making the gloves slippery and shortening the lifespan of the gloves. Increasing the thickness of the coating layer makes the fibers exposed when the coating layer wears, making the gloves slippery and shortening the lifespan of the gloves. Increasing the strength of the fibers in the knitted glove body makes the coating layer wear away, making the gloves slippery and shortening the lifespan of the gloves.

[0005] The present invention has been made in consideration of these circumstances, and an object of the present invention is to provide an anti-slip glove that allows easy gripping of an object, is excellent in workability, and can maintain anti-slip properties for a long period of time. [Means for solving the problem]

[0006] The palm region includes the carpal bones and metacarpal bones, which correspond to the fingers, even though they are in the palm. The inventors focused on the fact that when a worker holds or carries an object, he or she presses the lower part of the palm against the object and supports and balances the object with the parts corresponding to the fingers. In other words, the inventors discovered that by focusing on reinforcing the lower part of the palm, where a large force is applied, and the fingers, which provide balance, it is possible to provide anti-slip gloves that are easy to grip objects, have excellent workability, and maintain anti-slip properties for a long period of time, and thus completed the present invention.

[0007] That is, the non-slip glove according to one embodiment of the present invention comprises a knitted glove body made of fiber, which has a bag-shaped main body portion formed to cover the palm and back of the hand of a wearer, cylindrical first to fifth finger portions with bottoms extending from the main body portion to cover the wearer's first to fifth fingers, respectively, and a cylindrical hem portion extending in the opposite direction from the first to fifth finger portions, a rubber or resin coating layer laminated on the palm portion of the knitted glove body and the palm side of the first to fifth finger portions, and a rubber or resin reinforcing portion laminated between the knitted glove body and the coating layer, and the reinforcing portion is arranged at a position on the palm side that corresponds to at least the scaphoid, lunate, hamate, pisiform bones, and carpometacarpal joints of the third to fifth fingers when the glove is worn.

[0008] The anti-slip gloves have reinforced sections on the palm side corresponding to the scaphoid, lunate, hamate, pisiform, and carpometacarpal joints of the third to fifth fingers when worn, i.e., the lower palm area of ​​the anti-slip gloves where a large force is applied and the finger areas that provide balance. Because the reinforced sections are laminated between the knitted glove body and the coating layer, they are less likely to peel off. Therefore, the anti-slip gloves can maintain their anti-slip properties for a long period of time. Furthermore, because the anti-slip gloves do not require reinforced sections on the fingertips, they are easy to grip objects and offer excellent workability.

[0009] It is preferable that the reinforcing portion is not disposed at a position on the palm side corresponding to the metacarpophalangeal joints of the second to fourth fingers when worn. By not disposing the reinforcing portion at a position on the palm side corresponding to the metacarpophalangeal joints of the second to fourth fingers when worn in this way, the workability of the anti-slip glove can be further improved.

[0010] It is preferable that the reinforced portion is not disposed at a position on the palm side corresponding to the metacarpophalangeal joint of the fifth finger when worn. By not disposing the reinforced portion at a position on the palm side corresponding to the metacarpophalangeal joint of the fifth finger when worn in this way, the workability of the anti-slip glove can be further improved.

[0011] The reinforcing part penetrates the knitted glove body, and the area of ​​the reinforcing part where the rubber or resin has penetrated to the inner surface of the knitted glove body is preferably 20% to 90% of the area of ​​the reinforcing part. By setting the area of ​​the region where the rubber or resin has penetrated to the inner surface of the knitted glove body within the above range, peeling of the reinforcing part can be further suppressed while maintaining the workability of the anti-slip glove.

[0012] In the region where the reinforcing part is laminated, the proportion of the stitches on the inner surface of the knitted glove body that are covered by infiltration of rubber or resin is preferably 10% to 80%. By setting the proportion of the stitches on the inner surface of the knitted glove body that are covered by infiltration of rubber or resin within the above range, peeling of the reinforcing part can be further suppressed while maintaining the workability of the anti-slip glove.

[0013] Here, "inner surface" refers to the surface that comes into contact with the hand when the glove is worn, and "outer surface" refers to the opposite surface. The "area of ​​the reinforced portion" refers to the area enclosed by a line drawn 1 cm inward from the edge of the reinforced portion. If there are multiple such areas, the total area is the sum of all areas. The "area of ​​the reinforced portion where the rubber or resin has permeated to the inner surface of the knitted glove body" (hereinafter simply referred to as the "permeation area") refers to the area where the rubber or resin has permeated to the surface when the glove is turned inside out and the inner surface is observed. The area of ​​the permeation area refers to the area where the rubber or resin can be confirmed on the inner surface of the glove body by fixing the permeation area on a horizontal table, taking a photograph from directly above, and analyzing the image. The image analysis can be performed visually, or an image analysis program, such as Adobe PhotoShop, can be used to determine the area of ​​the reinforced portion and the permeation area on a pixel-by-pixel basis. The term "stitches covered by permeation of rubber or resin" refers to stitches where the yarns that make up the stitches are entirely covered by the permeation area. It is sufficient that the entire stitch is covered when viewed from above, and the surface of the covered portion does not need to protrude beyond the surface formed by the yarn that makes up the stitch. The number of stitches is counted visually, but if the stitches are fine, they may be counted by enlarging the image of the photograph taken by the above method. The "stitch ratio" refers to the ratio of the number of covered stitches described above to the number of stitches included in the area of ​​the reinforcing part. [Effects of the Invention]

[0014] As described above, the non-slip glove of the present invention allows easy gripping of an object, has excellent workability, and can maintain its non-slip properties for a long period of time. [Brief explanation of the drawings]

[0016] A glove according to one embodiment of the present invention will be described in detail below.

[0017] The non-slip glove 1 shown in FIGS. 1 and 2 comprises a knitted glove body 10, a coating layer 20, and a reinforcing part 30.

[0018] <Knitted gloves> The knitted glove body 10 has a main body portion 10a, bottomed, cylindrical first to fifth finger portions (hereinafter collectively referred to as "finger portions 10b"), and a cylindrical hem portion 10c. The main body portion 10a is formed in a bag shape to cover the palm and back of the wearer's hand, and the five finger portions 10b extend from the main body portion 10a to cover the wearer's first to fifth fingers, respectively. The hem portion 10c extends in the opposite direction from the finger portions 10b. The knitted glove body 10 is made of fiber. The non-slip glove 1 has a knitted glove body, which is highly flexible. Furthermore, the knitted glove body 10 can be seamlessly formed using a glove knitting machine, which allows it to be prepared at a relatively low cost and provides the non-slip glove 1 with an excellent fit and feel.

[0019] Examples of yarns constituting the knitted glove body 10 include cotton yarn, polyester yarn, nylon yarn, polyethylene yarn, polypropylene yarn, acrylic yarn, para-aramid yarn, meta-aramid yarn, polyparaphenylenebenzoxazole (PBO) yarn, ultra-high molecular weight polyethylene yarn, stretched polyethylene yarn, glass fiber yarn, metal fiber yarn, and composite yarns thereof. In addition, elastic fibers such as natural rubber fiber and polyurethane fiber can also be used in combination to impart stretchability.

[0020] The yarn constituting the knitted glove body 10 can be spun yarn, filament yarn, composite yarn, or a combination thereof. When using spun yarn as the yarn, a single yarn, a two-ply yarn, or a yarn having a greater number of yarns can be used, and a yarn having a thickness corresponding to a cotton count of 3.3 or more and 100 or less can be used in combination with these yarns. When using filament yarn as the yarn, or when used in combination with spun yarn or composite yarn, a yarn having a thickness of 50 dtex or more and 1500 dtex can be used in single yarn, two-ply yarn, or a combination of these.

[0021] <Coating layer> The coating layer 20 is laminated on the palm portion and the palm side of the first to fifth finger portions of the knitted glove body 10. The coating layer 20 is made of rubber or resin. The coating layer 20 imparts anti-slip properties to the non-slip glove 1. The coating layer 20 can also impart functions such as stain resistance when working with oil and waterproofing to the non-slip glove 1.

[0022] Examples of the main component of the rubber constituting the coating layer 20 include natural rubber, acrylonitrile butadiene rubber, chloroprene rubber, acrylic rubber, isoprene rubber, styrene-isoprene block copolymer, silicone rubber, and mixtures thereof. Among these, natural rubber, acrylonitrile butadiene rubber, and chloroprene rubber are preferred from the viewpoints of versatility, adhesion to the fibers of the knitted glove body 10, flexibility, and abrasion resistance.

[0023] The main component of the resin that constitutes the coating layer 20 may include polyurethane, polyvinyl chloride, and mixtures thereof.

[0024] As shown in Figures 1 and 2, the coating layer 20 is formed on the palm portion of the main body 10a of the knitted glove body 10 and on the palm side of the finger portions 10b. In particular, it is preferable that the coating layer 20 is formed in a position on the palm side corresponding to the carpal bone A to the metacarpal bone B when the anti-slip glove 1 is worn (see Figures 4 and 5 for the position of each bone, and the same applies below). This not only protects the palm portion but also gives the anti-slip glove 1 a high grip.

[0025] The coating layer 20 may cover the entire finger portion 10b on the back side of the knitted glove body 10. Alternatively, it may be formed at a position on the back of the hand corresponding to the metacarpophalangeal joint C when worn. By forming the coating layer 20 at a position on the back of the hand corresponding to the metacarpophalangeal joint C, the metacarpophalangeal joint C can be protected. In addition, in FIG. 2, the coating layer 20 is formed to protect the distal interphalangeal joint D, but if priority is given to finger movement, it is preferable to not form the coating layer 20 near the distal interphalangeal joint D but only form the coating layer 20 closer to the fingertip.

[0026] The coating layer 20 is formed at least in the portion where the reinforcing portion 30 described below is laminated. The lower limit of the coverage rate of the coating layer 20 relative to the area of ​​the reinforcing portion 30 is preferably 80%, more preferably 90%, and even more preferably 100%, i.e., the entire surface of the reinforcing portion 30 is covered with the coating layer 20. It is also preferable that at least 80% or more, more preferably 90% or more of the peripheral length of the reinforcing portion 30 is covered with the coating layer 20.

[0027] The average thickness of the coating layer 20 in the region where the reinforcement portion 30 is laminated depends on the average thickness of the knitted glove body 10. The lower limit of the average thickness of the coating layer 20 is preferably 0.15 mm, more preferably 0.35 mm, and even more preferably 0.55 mm. On the other hand, the upper limit of the average thickness of the coating layer 20 is preferably 1.10 mm, more preferably 0.90 mm, and even more preferably 0.70 mm. If the average thickness of the coating layer 20 is below the lower limit, the durability of the non-slip glove 1 may be insufficient. Conversely, if the average thickness of the coating layer 20 exceeds the upper limit, the flexibility of the non-slip glove 1 may be reduced, making it difficult to use. The "average thickness" is the average value of values ​​measured at 10 random points on the cross section of an object using a digital microscope (e.g., Keyence Corporation's "VHX-900"). The average thickness of the coating layer 20 is measured near the center of the reinforcement portion 30 (e.g., the center of the palm).

[0028] <Reinforcement part> 3, the reinforcing part 30 is laminated between the knitted glove body 10 and the coating layer 20. The reinforcing part 30 is made of rubber or resin.

[0029] The main components of the rubber and resin constituting the reinforcing portion 30 may be the same as the main components of the rubber and resin constituting the coating layer 20. The main components of the rubber and resin constituting the reinforcing portion 30 are preferably the same as the main components of the rubber and resin constituting the coating layer 20, as this can prevent peeling at the interface, but they may also be different.

[0030] The reinforcing portion 30 is arranged at a position on the palm side corresponding to at least the navicular bone E, lunate bone F, hamate bone G, pisiform bone H and carpometacarpal joints I of the third to fifth fingers when the glove is worn.

[0031] The scaphoid E, lunate F, hamate G, and pisiform H are included in the carpal bones A. Here, the carpal bones A will be explained. When grasping an object, the hand is bent, and the carpal bones A, although located inside the palm, correspond to the fingers and are the parts to which a strong force is applied. The inventors have recognized that the parts of a glove corresponding to the carpal bones A are particularly susceptible to wear. The inventors have also recognized that, because the parts corresponding to the carpal bones A support the object when grasping, when holding an object with edges, the pressure causes pain, and that among the carpal bones A, the scaphoid E, lunate F, hamate G, and pisiform H are the parts to which a strong force can be applied, although the range of motion of the joints surrounding them is narrow.

[0032] In other words, the positions on the palm side of the anti-slip glove 1 corresponding to the navicular bone E, lunate bone F, hamate bone G, pisiform bone H, and carpometacarpal joints I of the third to fifth fingers when worn, where the reinforcing portion 30 of the anti-slip glove 1 is arranged, are joint areas that hardly move when the hand is clenched or opened, and are areas where a strong force is applied when grasping an object, so forming the reinforcing portion 30 in these areas can prevent wear of the anti-slip glove 1. In addition, since the reinforcing portion 30 is arranged between the knitted glove body 10 and the coating layer 20, peeling can be prevented.

[0033] The reinforcing portion 30 is not disposed at a position on the palm side corresponding to the metacarpophalangeal joints C of the second to fifth fingers when the glove is worn. By not disposing the reinforcing portion 30 at a position on the palm side corresponding to the metacarpophalangeal joints C of the second to fifth fingers when the glove is worn in this way, the flexibility of the anti-slip glove 1 is ensured, and workability can be further improved.

[0034] It is preferable that the reinforcing part 30 is not arranged on the side surface of the first finger that corresponds to the fingertip side of the center of the metacarpal bone B of the first finger in the longitudinal direction when the glove is worn. This makes it less likely that the reinforcing part 30 will impede the movement of the first finger, ensuring the flexibility of the anti-slip glove 1 and further improving workability.

[0035] More preferably, the reinforcing part 30 is not arranged on the side surface of the first finger that corresponds to the metacarpal bone B of the first finger when worn. This makes it even less likely that the reinforcing part 30 will impede the movement of the first finger, ensuring the flexibility of the anti-slip glove 1 and further improving workability.

[0036] Edge 31 (see FIG. 1) of reinforcement part 30 in the fingertip direction of the second to fifth fingers is preferably located in a region corresponding to from the carpometacarpal joint I side of metacarpal bone B to two-thirds of the length of metacarpal bone B when worn. This makes it easier to move the second to fifth fingers, improving workability and making it easier to achieve the required reinforcing effect.

[0037] The reinforcing part 30 is preferably arranged on the side surface of the fifth finger that corresponds to the triangular bone J when worn. In other words, on the side surface of the fifth finger of the anti-slip glove 1, the reinforcing part 30 preferably extends from the palm side of the knitted glove body 10 to near the area that separates the palm from the back of the hand. This allows the palm area above the triangular bone J to be adequately protected when worn.

[0038] The fifth finger side edge 32 (see FIG. 1) of the reinforcing part 30 is preferably located near the area separating the palm from the back of the hand from the palm side of the knitted glove body 10. This improves the fit of the non-slip glove 1 while protecting the palm.

[0039] The wrist-side edge 33 of the reinforcing part 30 (see FIG. 1) is preferably located at a distance of 2 cm or less, more preferably 1 cm or less, from the position corresponding to the wrist-side edge 33 of the carpal bone A when worn. This makes it less likely that the reinforcing part 30 will impede wrist movement, ensuring flexibility of the anti-slip glove 1 and further improving workability. Furthermore, the reinforcing part 30 can adequately protect the palm area above the carpal bone A.

[0040] As shown in FIG. 3 , the reinforcing portion 30 penetrates the knitted glove body 10, and the rubber or resin forming the reinforcing portion 30 penetrates into the inner surface of the knitted glove body 10 in part of the reinforcing portion 30. The inner surface of the knitted glove body 10 is formed of fiber. Although such a knitted glove body 10 has a nice texture, applying strong force while gripping an object can cause slippage between the inner surface of the knitted glove body 10 and the palm, requiring additional force to grip the object stably. In the non-slip glove 1, the rubber or resin penetrates into the inner surface of the knitted glove body 10 in part of the reinforcing portion 30, thereby suppressing the above-mentioned slippage and making it easier to grip an object stably.

[0041] The lower limit of the area of ​​the region of the reinforcing part 30 where the rubber or resin has permeated to the inner surface of the knitted glove body 10 (the permeation region) is preferably 20% of the area of ​​the reinforcing part 30, more preferably 30%. On the other hand, the upper limit of the area of ​​the permeation region is preferably 90% of the area of ​​the reinforcing part 30, more preferably 80%. If the area of ​​the permeation region is less than the lower limit, slippage may occur between the inner surface of the knitted glove body 10 and the palm, making it difficult to stably grip an object. Furthermore, if the anti-slip glove 1 is worn and a strong force is applied while working, the coating layer 20 and the reinforcing part 30 may peel off from the knitted glove body 10. Conversely, if the area of ​​the permeation region exceeds the upper limit, the anti-slip glove 1 may become too hard, reducing workability.

[0042] The stitches 11 of the knitted glove body 10 (the portion surrounded by a dashed line in FIG. 6 is one stitch, and is composed of a needle loop 11a, a leg 11b, and a sinker loop 11c) appear so that the stitches forming the outer surface and the stitches forming the inner surface are continuous in directions perpendicular to each other. Specifically, when the stitches forming the outer surface are continuous in the wale direction, the stitches forming the inner surface are continuous in the course direction, and when the stitches forming the outer surface are continuous in the course direction, the stitches forming the inner surface are continuous in the wale direction. For example, FIG. 6 shows the knitted glove body 10 as seen from the inner surface. In the knitted glove body 10 of FIG. 6, the stitches on the front side, i.e., the inner surface side, are continuous in the course direction (x direction in FIG. 6), and the stitches on the back side, i.e., the outer surface side, are continuous in the wale direction (y direction in FIG. 6). In the area where the reinforcing portion 30 has penetrated into the stitches forming the outer surface of the knitted glove body 10, it is preferable that the reinforcing portion 30 penetrates continuously in the direction of the stitches forming the inner surface (the course direction in FIG. 6, i.e., the x direction). In other words, in the area where the reinforced portion 30 penetrates, it is preferable that the stitches (leg 11b) forming the outer surface side are almost entirely covered by the reinforced portion 30, while the stitches forming the inner surface side are visible. By configuring the reinforced portion 30 in this manner, peeling of the reinforced portion 30 can be prevented by the anchor effect. The lower limit of the proportion of stitches that form the outer surface side of the knitted glove body 10 that are covered by the reinforced portion 30 is preferably 70%, more preferably 80%. By setting the proportion of stitches at or above the lower limit, the peeling prevention effect due to the anchor effect can be easily achieved.

[0043] Even when the reinforcing part 30 penetrates to the inner surface of the knitted glove body 10, if the stitches (needle loops 11a and sinker loops 11c) are exposed on the inner surface of the knitted glove body 10, the fibers in the exposed part of the stitches are likely to slip between the hand and the knitted glove. Therefore, in the region where the reinforcing part 30 is laminated, it is preferable that at least a part of the stitches on the inner surface side of the knitted glove body 10 be covered by infiltrating rubber or resin.

[0044] In the region where the reinforcement portion 30 is laminated, the lower limit of the proportion of the stitches (needle loops 11a) on the inner side of the knitted glove body 10 that are covered by infiltrating rubber or resin is preferably 10%, more preferably 20%. On the other hand, the upper limit of the proportion of the stitches is preferably 80%, more preferably 70%. If the proportion of the stitches is below the lower limit, slippage may occur between the inner surface of the knitted glove body 10 and the palm, making it difficult to stably grasp an object. Furthermore, if the non-slip glove 1 is worn while working and strong force is applied, peeling may occur. Conversely, if the proportion of the stitches exceeds the upper limit, the non-slip glove 1 may become too hard, resulting in reduced workability. Since the sinker loops 11c are integrated with the pre-formed needle loops 11a, only the needle loops 11a are counted here. Furthermore, when the inside and outside of the knitted glove body 10 are reversed, the leg 11b described above corresponds to the needle loop 11a, and the needle loop 11a corresponds to the leg 11b with regard to penetration of the reinforced portion 30.

[0045] The reinforcing portion 30 can also serve to enhance the cushioning properties of the non-slip glove 1 when a strong force is applied. By providing cushioning properties to the non-slip glove 1, it is possible to improve work comfort. From this perspective, it is preferable that the reinforcing portion 30 penetrates into the knitted glove body 10.

[0046] To enhance cushioning properties, the reinforced portion 30 may be made porous. The proportion of air volume in the volume of the reinforced portion 30 is preferably 10% or more and 50% or less. If the proportion of air volume is below the lower limit, sufficient cushioning properties may not be provided. Conversely, if the proportion of air volume is above the upper limit, peeling and wear of the reinforced portion 30 may not be sufficiently prevented. The "proportion of air volume in the volume of the reinforced portion 30" can be calculated by observing a cross section near the center of the reinforced portion 30 (excluding the peripheral portion) with a microscope, and calculating the proportion of the area of ​​voids in the total area of ​​the reinforced portion 30, focusing on a continuous region located outside the yarns constituting the outermost surface of the knitted glove body 10 (i.e., excluding the portion that penetrates inward beyond the yarns constituting the outermost surface of the knitted glove body 10).

[0047] The average thickness of the reinforced portion 30 depends on the average thickness of the knitted glove body 10. The lower limit of the average thickness of the reinforced portion 30 is preferably 0.20 mm, more preferably 0.40 mm, and even more preferably 0.60 mm. On the other hand, the upper limit of the average thickness of the reinforced portion 30 is preferably 1.50 mm, more preferably 1.30 mm, and even more preferably 0.90 mm. If the average thickness of the reinforced portion 30 is below the lower limit, the durability, reinforcement, and cushioning effects may be insufficient. Conversely, if the average thickness of the reinforced portion 30 exceeds the upper limit, the reinforced portion 30 may be too hard. The "thickness of the reinforced portion 30" refers to the distance from the outermost surface of the reinforced portion 30 to the innermost end of the reinforced portion 30 when a perpendicular line is drawn from the outermost surface of the reinforced portion 30 to the inner surface of the glove. Even if the reinforced portion 30 is interrupted by yarns or voids forming the knitted glove body 10, the thickness of the reinforced portion 30 is measured from the outermost surface to the innermost end of the reinforced portion 30 using a digital microscope. Moreover, the "average thickness of the reinforcing portion 30" is the average value of the thickness of the reinforcing portion 30 measured at 10 points.

[0048] The ratio of the average thickness of the reinforcing portion 30 to the average thickness of the coating layer 20 is preferably 0.2:1 or more and 2:1 or less, more preferably 0.3:1 or more and 1.5:1 or less, and even more preferably 0.3:1 or more and 1:1 or less, at the center of the reinforcing portion 30. By keeping the ratio within the above range, it becomes easier to obtain the effects of durability, reinforcement, and cushioning, and the flexibility of the anti-slip glove 1 can be ensured, improving usability.

[0049] <Method of manufacturing the anti-slip gloves> The non-slip glove 1 can be manufactured by a method for manufacturing non-slip gloves, which includes a knitted glove body preparation step, a latex compound preparation step, a reinforcing part lamination step, and a coating layer lamination step.

[0050] (Knitted glove body preparation process) In the knitted glove body preparation step, the knitted glove body 10 is knitted.

[0051] The knitted glove body 10 can be knitted using the yarn constituting the above-mentioned knitted glove body 10 on a glove knitting machine or a whole garment knitting machine of, for example, 10G to 26G. Examples of the glove knitting machine include SFG-I and SWG021N2 manufactured by Shima Seiki.

[0052] (Latex compound preparation process) In the latex compound preparation step, a latex compound is prepared for forming the coating layer 20 and the reinforcing portion 30. The latex compound for the coating layer and the latex compound for the reinforcing portion may be prepared separately, but if the coating layer 20 and the reinforcing portion 30 have the same main component, they may be prepared as one type of latex compound.

[0053] In addition to the rubber or resin composition for forming the coating layer 20 or the reinforcing portion 30, the latex compound may contain stabilizers such as emulsifiers and surfactants, vulcanizing agents such as sulfur, vulcanization accelerators such as zinc oxide and zinc diethyldithiocarbamate, crosslinking agents such as diglycidyl ether, polyglycidyl ether, polycarbodiimide, blocked isocyanate, oxazoline group-containing polymers, and silane coupling agents, pH adjusters such as potassium hydroxide and ammonia, thickeners such as polyacrylic acid and carboxymethyl cellulose, pigments, antioxidants, and other compounding agents. Furthermore, if the reinforcing portion 30 is to be porous, in addition to chemical foaming agents and thermally expandable microcapsules, foaming agents and foam stabilizers may be added to mechanically foam the raw materials.

[0054] (Reinforcement lamination process) In the reinforcing portion lamination step, the reinforcing portion 30 is laminated at a desired location on the knitted glove body 10.

[0055] The reinforcing portion 30 can be formed by dip molding. Specifically, the reinforcing portion 30 is formed by selectively dipping the desired portion into a latex compound.

[0056] Generally, when forming the coating of the reinforcing portion 30 on the knitted glove body 10, the knitted glove body 10 is placed over a hand mold, and then the heated knitted glove body 10 is reacted with the latex compound, which has high thermal coagulation properties, or the knitted glove body 10, which has been impregnated with a coagulant, is reacted with the latex compound. This method prevents the latex compound from penetrating the entire thickness of the knitted glove body 10. In contrast, in the anti-slip glove 1, the latex compound is allowed to penetrate to the inner surface of the knitted glove body 10 during lamination of the reinforcing portion 30. Therefore, it is preferable that the latex compound used has low thermal coagulation properties and high stability. Furthermore, it is preferable that a coagulant is not used when laminating the reinforcing portion 30, or that the coagulant used has low coagulation power.

[0057] To laminate a strong reinforcing part 30, it is preferable that the reinforcing part 30 contains as few air bubbles as possible. To achieve this, since the knitted glove body 10 contains air, it is advisable to remove the air from the knitted glove body 10 during dip molding. In this case, the air inside the knitted glove body 10 is more easily removed if the stitches of the knitted glove body 10 are open. To open the stitches, it is advisable to use a hand mold with a palm that is larger than the one normally used. As a result, the reinforcing part 30 adheres more closely to the knitted glove body 10.

[0058] In order to laminate the flexible reinforcing part 30, it is preferable to form the reinforcing part 30 as a foam layer. In this case, the anti-slip glove 1 can be endowed with higher cushioning properties.

[0059] (Coating layer lamination process) In the coating layer laminating step, a coating layer 20 is further laminated at a desired location on the knitted glove body 10 on which the reinforcing portion 30 has been laminated. This coating layer 20 is formed so as to cover the reinforcing portion 30 as well.

[0060] The coating layer 20 can be formed by reacting a highly thermosetting latex compound with the heated knitted glove body 10, or by immersing the knitted glove body 10 with the reinforcement 30 in a coagulant and then reacting it with a latex compound. In this case, the coating layer 20 preferably penetrates the area in direct contact with the knitted glove body 10 to a depth of 10% to 70% of the average thickness of the knitted glove body 10, as shown in Figure 3, from the viewpoints of preventing peeling and maintaining flexibility.

[0061] After the coating layer 20 is laminated, it is heat-cured and removed from the hand mold to obtain the anti-slip glove 1. Note that a water washing step may be performed at any time between the time when the coating layer 20 is laminated and the time when the heat-cured anti-slip glove 1 is removed in order to remove excess coagulant, emulsifier, vulcanization accelerator, etc. from the anti-slip glove 1.

[0062] Also, a known anti-slip treatment may be applied to the surface of the coating layer 20. Examples of methods for imparting anti-slip properties include a method of creating irregularities on the outer surface of the coating layer 20 using particles, a method of making the coating layer 20 a foam layer, a method of providing a foam layer on the outer surface of the coating layer 20, a method of applying deliquescent particles to the coating layer 20 before it hardens and removing them after heating to form an irregular shape when forming the coating layer 20, a method of swelling the coating layer 20 with a solvent when forming it to create an irregular pattern, and a method of creating irregularities by hot pressing.

[0063] <Advantages> The anti-slip glove 1 has reinforcement portions 30 on the palm side corresponding to the navicular bone E, lunate bone F, hamate bone G, pisiform bone H, and carpometacarpal joints I of the third to fifth fingers when worn, i.e., on the lower palm area of ​​the anti-slip glove 1 where a large force is applied and on the finger portions 10b that provide balance. Since the reinforcement portions 30 are laminated between the knitted glove body 10 and the coating layer 20, they are less likely to peel off. Therefore, the anti-slip glove 1 can maintain its anti-slip properties for a long period of time. Furthermore, since the anti-slip glove 1 does not require reinforcement portions 30 on the fingertips, it is easy to grip objects and is excellent in workability.

[0064] [Other embodiments] The present invention is not limited to the above-described embodiment, and can be implemented in various other forms, including those described above, with various modifications and improvements.

[0065] In the above embodiment, the case where the reinforcement portion is not disposed at a position on the palm side corresponding to the metacarpophalangeal joints of the second to fifth fingers when worn has been described. However, the present invention also contemplates an anti-slip glove in which the reinforcement portion is not disposed at a portion of the palm side corresponding to the metacarpophalangeal joints of the second to fifth fingers when worn. For example, the anti-slip glove may be configured so that the reinforcement portion is not disposed at a position on the palm side corresponding to the metacarpophalangeal joints of the second to fourth fingers when worn. Furthermore, the anti-slip glove may be configured so that the reinforcement portion is not disposed at a position on the palm side corresponding to the metacarpophalangeal joint of the fifth finger when worn. Even with these configurations, the flexibility of the anti-slip glove can be ensured, further improving workability.

[0066] In the above embodiment, the case where the reinforcing portion penetrates to the inner surface of the knitted glove body has been described, but the reinforcing portion does not have to penetrate to the inner surface of the knitted glove body. [Example]

[0067] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to the following examples.

[0068] (Knitted glove body) Three 20-count cotton yarns were knitted into gloves using a 10-gauge glove knitting machine SGF-I manufactured by Shima Seiki Co., Ltd. The knitted gloves were washed with hot water to remove oil, and the knitted glove bodies were prepared.

[0069] (Pre-vulcanization latex) A pre-vulcanization latex was prepared having the compounding amount in solid content shown in Table 1. The total solid content of the pre-vulcanization latex was adjusted to 52.8 mass %.

[0070] [Table 1]

[0071] (Latex for reinforcement) The pre-vulcanization latex in Table 1 was pre-vulcanized at 40°C for 1 hour to obtain pre-vulcanized latex, and the latex for the reinforcing part was prepared with the blending amounts shown in Table 2. The latex for the reinforcing part was adjusted to a solid content of 49.1% by mass and a viscosity of 1000 mPa s. The viscosity was measured using a B-type viscometer at V6 (6 rpm) and a temperature of 25°C.

[0072] [Table 2]

[0073] (Latex for coating layer) The pre-vulcanization latex in Table 1 was pre-vulcanized at 40°C for 12 hours to obtain a pre-vulcanized latex, and the coating layer latex was prepared with the blending amounts shown in Table 3. The coating layer latex was prepared to have a solid content of 50.9% by mass and a viscosity of 2000 mPa s.

[0074] [Table 3]

[0075] (Making anti-slip gloves) The knitted glove body was placed on a hand mold at room temperature of 27°C, and the lower part of the palm was slowly dipped into the latex for the reinforcement and then removed. The hand mold was placed in an oven and dried at 100°C for 20 minutes to form the reinforcement. After cooling at room temperature, the hand mold was heated in an oven at 70°C and dipped into the latex for the coating layer so that the entire palm and the back of the fingers in the areas corresponding to the nails (one-third of the length of the fingers from the tips) were covered. After the surface was dried, the hand mold was dipped in xylene to form the anti-slip pattern. The hand mold was then placed in an oven and dried at 100°C for 20 minutes. The glove was removed from the hand mold and washed with water to remove the dispersant and excess chemicals. The glove was then placed back on the hand mold and placed in an oven for vulcanization at 120°C for 40 minutes. After cooling at room temperature, the glove was removed from the hand mold to obtain the anti-slip glove.

[0076] The reinforced area of ​​the anti-slip gloves was formed in the area surrounded by the center of the metacarpal bones of the second to fifth fingers, the carpometacarpal joint of the first finger, a position 1 cm toward the arm from the lunate bone, and a position covering the pisiform bone. As a result, the anti-slip gloves were confirmed to be easy to work with and highly cushioned, as they do not interfere with the flexion and extension of the fingers and wrist.

[0077] The reinforcement penetrated 74% of the glove interior, covering 47% of the inner stitches of the knitted glove body. Microscopic examination of the cross section of the glove at the center of the reinforcement revealed that the average thickness of the reinforcement was 0.89 mm, and the average thickness of the covering layer was 0.80 mm. This non-slip glove was confirmed to have excellent abrasion resistance and grip. [Industrial Applicability]

[0078] As described above, the non-slip glove of the present invention allows easy gripping of an object, has excellent workability, and can maintain its non-slip properties for a long period of time. [Explanation of symbols]
