Description

Non-slip gloves

The present invention relates to a non-slip glove.

Non-skid gloves with a coating layer laminated on at least the palm side of the fiber gloves are used as the anti-slip gloves. An anti-skid glove that further improves the anti-slipping effect while maintaining the flexibility of the glove by containing bubbles in the coating layer is known.

However, if air bubbles are included in the coating layer, the anti-slip effect of the anti-slip gloves when gripping via a liquid material is improved, but the wear resistance tends to be reduced. As a method for improving the wear resistance, a method of reducing the ratio of bubbles in the pressed portion by hot pressing a coating layer containing bubbles has been proposed (for example, JP-A-2006-169676, JP-A-2007- No. 231428) is desired to further improve wear resistance. In addition, a glove having a palm with a plurality of filler-containing convex portions has been proposed (see, for example, JP-A-2013-104134), but the convex portion and the glove covering portion are formed of two layers. Therefore, the process becomes complicated and the strength between the layers is not sufficient, and further strength improvement is desired. Furthermore, a method for forming irregularities by coating the second coating layer containing particles from above the coating layer has been proposed (see, for example, JP-A-2013-177711). Since the layer is composed of two layers, further improvement in strength is desired.

JP 2006-169676 A JP 2007-231428 A JP2013-104134A JP 2013-177711 A

The present invention has been made based on the above-described circumstances, and an object thereof is to provide a non-slip glove excellent in anti-slip effect, wear resistance, strength and flexibility.

The invention made to solve the above problems is a non-slip glove comprising a fiber glove body covering a wearer's hand and a covering layer covering at least a part of the outer surface of the palm region of the glove body. The coating layer is made of a non-foamed rubber composition or a non-foamed resin composition, and a concavo-convex shape is formed by pressing on the coating layer in the palm region, and the average thickness of the concave portions in the concavo-convex shape is 50 μm. The average width of the recesses is 100 μm or more and 15 mm or less.

The anti-skid glove has an excellent anti-slipping effect because it includes a coating layer that covers at least a part of the outer surface of the palm region of the glove body. Further, since the coating layer is composed of a non-foamed rubber composition or a resin composition, there is almost no bubble other than the foam that accidentally bites during coating, and the bubble ratio is further reduced by pressing, Since the coating layer is firmly fixed to the glove body, the anti-skid glove is excellent in wear resistance. Furthermore, since the average thickness of the recesses in the concavo-convex shape by pressing is equal to or more than the above lower limit, it is possible to prevent the glove body from being exposed from the recesses during wearing, and the durability of the antiskid gloves is improved. Moreover, since the average thickness of the said recessed part is below the said upper limit, a recessed part becomes a crease and is easy to bend, and the said anti-skid glove exhibits favorable softness | flexibility. In addition, since the average width of the recesses is within the above range, an effect of oiling away by the recesses is obtained, and the antiskid gloves are excellent in gripping force. In addition, since the coating layer is composed of one layer, it is excellent in strength. In addition, since the coating layer has a concavo-convex shape, the pattern due to the concavo-convex shape becomes thin when the wear of the non-slip glove progresses, and therefore the concavo-convex shape can be used as an indicator of glove wear. It is possible to prevent the use of gloves when the non-slip effect is reduced.

It is preferable that the coating layer is mainly composed of rubber that has been heat vulcanized or thermally crosslinked. Thus, the production of the coating layer is facilitated by using heat-vulcanized or heat-crosslinked rubber as a main component. Specifically, it is possible to easily fix the concavo-convex shape by forming a concavo-convex easily by performing a pressing process in a state where the molecular chains are weakly connected, and then performing thermal vulcanization or thermal crosslinking.

The rubber is preferably an acrylonitrile-butadiene copolymer. By using acrylonitrile-butadiene copolymer as a main component in this way, the wear resistance when gripping via an oily liquid is further increased and the life is extended.

The total area ratio of the recesses in the region where the uneven shape is formed is preferably 10% or more and 93% or less. Thus, by making the total area ratio of the said recessed part in the said range, a grip force can further be heightened, maintaining a softness | flexibility by the recessed part of the said anti-skid glove.

The average unevenness difference of the uneven shape is preferably 0.15 mm or more and 0.7 mm or less. Thus, by making the average of the unevenness difference within the above range, it is possible to further enhance the antiskid effect in the oil work of the antiskid gloves.

The ratio of the average thickness of the concave portion to the average thickness of the convex portion in the uneven shape is preferably 10% or more and 70% or less. Thus, the ratio of the average thickness of the concave portion to the average thickness of the convex portion is within the above range, whereby the antiskid effect of the antiskid gloves can be further enhanced.

Note that the above “palm area” means an area (including the thumb and four fingers) from the wrist to the fingertip that is an inner surface when the object is grasped. The “average thickness of the recess” means the average distance from the innermost surface of the coating layer to the bottom surface of the recess, and the “average thickness of the projection” means from the innermost surface of the coating layer to the upper bottom surface of the projection. Means the average distance. In addition, “the total area ratio of the recesses in the concavo-convex shape forming region” means the total plan view area of all the recesses in the region where the concavo-convex shape is formed with respect to the plan view area of the region where the concavo-convex shape is formed. Is the ratio. The “total planar view area of the recesses” refers to the area of the recess in the plan view in the area where the concave and convex shape is formed, with the bottom surface area of the recess in the cross section of the anti-skid glove in the plan view. The total area. In addition, when the rising part from the concave bottom surface to the convex curve is smoothly curved and the concave bottom surface region is unclear, the intersection line between the surface extending the concave bottom surface and the surface extending the convex side is the concave bottom region The outer edge.

As described above, the present invention can provide an antiskid glove excellent in antiskid effect, abrasion resistance, strength and flexibility.

It is the typical top view which looked at the anti-skid glove concerning one embodiment of the present invention from the palm side. It is a typical fragmentary sectional view of the uneven | corrugated shaped part of the anti-skid glove of FIG. It is the typical top view which looked at the anti-skid glove of FIG. 1 from the back side of the hand. It is a typical partial enlarged plan view of the palm region of the non-skid glove of FIG. It is a typical expanded sectional view of the convex part of the anti-skid glove of FIG. It is a typical partial enlarged plan view of a palm region of a non-skid glove concerning other embodiments of the present invention.

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

As shown in FIG. 1, the non-slip glove of the present embodiment includes a fiber glove body 1 that covers the wearer's hand and a covering layer 2 that covers at least a part of the outer surface of the palm region of the glove body 1. Prepare.

<Glove body>
The glove body 1 is formed by knitting fibers in a glove shape. The glove body 1 covers a body part formed in a bag shape so as to cover the wearer's hand body, an extension part extending from the body part so as to cover the wearer's finger, and a wrist of the wearer. And a cylindrical skirt extending from the main body portion in the direction opposite to the extending portion. The extension part is a first finger part that covers the wearer's first finger (thumb), second finger (index finger), third finger (middle finger), fourth finger (ring finger), and fifth finger (small finger), respectively. , Second finger portion, third finger portion, fourth finger portion and fifth finger portion. The first to fifth finger portions are formed in a cylindrical shape with the fingertip portion closed. Moreover, the said skirt part has an opening part into which a wearer can insert a hand.

The fiber constituting the glove body 1 is not particularly limited, and is not limited to natural fibers such as cotton and hemp, polyamide fibers, polyester fibers, rayon fibers, acrylic fibers, aramid fibers, high-strength polyethylene fibers, polyurethane fibers, and polyparaphenylene. Examples thereof include synthetic fibers such as terephthalamide fiber and ultrahigh strength polyethylene fiber, metal fibers such as stainless steel, and inorganic fibers such as glass fiber. These fibers may be used alone or in combination of two or more. For example, as a fiber used by mixing two kinds, a composite yarn obtained by covering a stainless fiber with nylon or the like can be exemplified. The glove body 1 is formed by knitting yarns made of the fibers. However, gloves formed by cutting and sewing a woven or nonwoven fabric using the fibers into a glove shape may be used. Among them, gloves knitted by a seamless knitting machine are preferable because there are no seams.

The number of knitting gauges of the glove body 1 is not particularly limited as long as the glove body 1 having appropriate strength and flexibility can be obtained. For example, 78 to 778 dtex nylon crimped yarn, equivalent to 5 to 40 cotton counts When the glove body 1 is knitted with a seamless knitting machine using cotton yarn or the like, it is preferably 10 gauge or more and 18 gauge or less.

The upper limit of the average thickness of the glove body 1 is preferably 1 mm, and more preferably 0.8 mm. On the other hand, the lower limit of the average thickness of the glove body 1 is preferably 0.1 mm, and more preferably 0.2 mm. When the average thickness of the glove body 1 exceeds the above upper limit, the thickness of the anti-skid glove becomes large, so that flexibility is lowered and workability at the time of wearing may be lowered. On the other hand, when the average thickness of the glove body 1 is less than the lower limit, the strength of the glove itself is lacking and the durability may be reduced. Note that the average thickness of the glove body 1 can be arbitrarily determined in a region where the coating layer 2 is not coated by using a constant pressure thickness measuring instrument (for example, “PG-15” manufactured by Teclock Co., Ltd.) according to JIS-L1086 / L1096. It is the average value of the values obtained by measuring the five locations.

The glove body 1 may be subjected to various treatments using, for example, a softener, a water / oil repellent, an antibacterial agent, etc. May be given. Moreover, the chemical | medical agent which shows such a function may be kneaded into the fiber itself.

<Coating layer>
The covering layer 2 covers at least part of the outer surface of the palm side and back of the hand side of the glove body 1. The coating layer 2 is composed of a non-foamed rubber composition or a resin composition, and a concavo-convex shape (projections 3 and recesses 4) is formed on the coating layer 2 in the palm region by pressing.

The covering layer 2 is covered over the entire palm area on the palm side as shown in FIG. Here, covering will be described with reference to a schematic partial cross-sectional view of the anti-skid glove 1 of FIG. In FIG. 2, reference numeral 12 indicates a cross section of the fiber bundle of the glove body 1. The glove body 1 has a gap on the inside and outside of the fiber bundle 12, and the rubber composition or the resin composition that is not foamed enters the gap, so that the glove body 1 is composed of the rubber composition or the resin composition. The covering layer 2 is impregnated on the outer surface side of the palm region of the glove body 1, and the covering layer 2 is firmly fixed to the glove body 1. In addition, since the inner surface side of the glove body 1 is in direct contact with the hand, it is preferable that the fiber bundle 12 is exposed without being completely covered with the coating layer 2 when viewed from the inner surface side.

The main component of the non-foamed rubber composition or resin composition constituting the coating layer 2 is not particularly limited, but includes acrylonitrile-butadiene copolymer, natural rubber, chloroprene rubber, polyvinyl chloride (PVC), polyurethane and the like. Can be used. The “main component” is a component having the highest content, for example, a component having a content of 50% by mass or more.

The covering layer 2 is preferably composed mainly of heat-cured or heat-crosslinked rubber. Thus, the production of the coating layer is facilitated by using heat-vulcanized or heat-crosslinked rubber as a main component. Specifically, it is possible to easily fix the concavo-convex shape by forming a concavo-convex easily by performing a pressing process in a state where the molecular chains are weakly connected, and then performing thermal vulcanization or thermal crosslinking.

The rubber is preferably acrylonitrile-butadiene copolymer, natural rubber or chloroprene rubber. By using such rubber, the anti-skid glove is excellent in economical aspect, processed face, elasticity, durability, weather resistance and the like. Among the above rubbers, an acrylonitrile-butadiene copolymer is preferable. By using an acrylonitrile-butadiene copolymer, the wear resistance when gripping via an oily liquid is further increased, and the life of the non-skid gloves is prolonged.

In addition, a well-known crosslinking agent, vulcanization accelerator, anti-aging agent, thickener, plasticizer, pigment and the like may be added to the rubber composition or resin composition.

An uneven shape by press working is formed on the outer surface of the covering layer 2 in the region excluding the nail region 5 and the finger crotch region 6. On the other hand, the covering layer 2 of the nail region 5 and the finger crotch region 6 is not formed with an uneven shape and has a smooth surface. Further, as shown in FIG. 3, the back side of the hand of the glove body 1 is covered with the coating layer 2 only in the region on the tip side of each finger, and the coating layer 2 laminated on the back side of the hand is uneven. No shape is formed and it has a smooth surface. However, since it is necessary to press from the back side of the hand at the time of pressing, an uneven shape may be formed also on the coating layer 2 laminated on the back side of the hand.

Plural protrusions 3 are arranged in parallel in the middle finger direction A (the direction of a straight line connecting the center of the bottom of the glove body 1 and the center of the middle finger). One convex part 3 has a bent part as shown in FIG. 4 and is continuously formed with the concave part 4 sandwiched in a direction orthogonal to the middle finger direction. The bent portion is S-shaped, and the start point of the S-character (position corresponding to the writing start position of the S-character) is the end point of the adjacent S-character (position corresponding to the writing end position of the S-character). Link. In addition, this S-shape has a substantially hexagonal outer shape (the thick broken line portion in FIG. 4) in plan view. In addition, as shown in FIG. 1, the convex part 3 is arrange | positioned over the whole palm area | region of the glove body 1 except a part (nail area | region 5 and finger crotch area | region 6 grade | etc.,).

The part other than the convex part 3 in the substantially hexagonal shape forms a part of the concave part 4. A part of the concave portion 4 is located in the vicinity of the start point and the end point of the S-shape, is surrounded by the convex portion 3 constituting the S-shape, and has a cut shape from the outer periphery of a substantially hexagonal shape (hereinafter referred to as “the cut concave portion 4a”). ”). A portion between the convex portions 3 arranged in the middle finger direction forms a main body portion of the plurality of concave portions 4 (hereinafter also referred to as “long-chain concave portion 4 b”). The cut recess 4a is connected to the long-chain recess 4b and constitutes the recess 4 as a whole.

This recess 4 is likely to be the initiation of wrinkles that occur when a finger is bent, and the softness of the glove can be improved by providing the recess 4 in this way. Specifically, the direction of the long-chain recess 4b is the direction of a heel that is formed by bending a palm when four fingers other than the first finger (thumb) are bent (hereinafter referred to as “direction for facilitating bending of the finger”). "). For this reason, when the said long-chain-shaped recessed part 4b bends and turns, it becomes easy to follow a motion of a palm and higher flexibility is exhibited.

Although it does not restrict | limit especially as a cross-sectional shape (shape of the surface which cut | disconnected one convex part 3 in the width direction) of the convex part 3 in the said uneven | corrugated shape, It is a surface side rather than the width | variety on the glove body side of the convex part 3 A substantially trapezoidal shape with a narrow width is mentioned.

Also, other shapes can be selected according to the application. For example, in the oil work, the central portion of the convex portion 3 in the concave and convex shape is preferably raised from the other portion so that oil does not collect between the convex portion 3 and the grasped object. Specifically, the center portion of the upper bottom surface of the convex portion 3 is rounded and expanded (see FIG. 5A), the width of the convex body 3 on the glove body side and the upper bottom surface side is both narrow, and the width of the intermediate portion is wide. Examples of the shape (see FIG. 5B). Thus, grip power can be heightened because the central part of the convex part 3 is raised from the other part. The “center portion of the convex portion” refers to a portion excluding the vicinity of the edge of the convex portion in plan view.

In addition, the vicinity of the edge of the convex portion 3 in the above concavo-convex shape may be raised from other portions. Specifically, the shape (refer FIG.5 (c)) etc. in which the center part of the upper bottom face of the convex part 3 was depressed are mentioned. As described above, the vicinity of the edge of the convex portion 3 is raised from the other portion, so that the convex portion 3 is easily deformed and the followability to the grasped object can be enhanced.

In general, when an uneven shape is formed on a non-slip glove, the flexibility of the portion where the uneven shape of the anti-slip glove is formed is improved, but the tear strength is reduced at the base of the convex part 3, and the use of the anti-slip glove The coating layer 2 may be easily deteriorated. On the other hand, in the anti-skid glove, the nail region 5 and the finger crotch region 6 are not particularly formed in the covering layer 2 of the nail region 5 and the finger crotch region 6 which are easily subjected to a tensile load and easily deteriorate. The strength can be maintained and deterioration of the coating layer 2 can be prevented.

The upper limit of the total area ratio of the recesses 4 (hereinafter also referred to as “occupation ratio of the recesses 4”) in the region where the uneven shape of the coating layer 2 is formed is preferably 93%, more preferably 80%. On the other hand, as a minimum of the occupation rate of the recessed part 4, 10% is preferable and 15% is more preferable. When the occupancy rate of the recessed part 4 exceeds the said upper limit, the total area of the convex part 3 in an uneven | corrugated shaped formation area | region will decrease, there exists a possibility that a contact area with a holding | gripping object may be insufficient and a grip force may not fully be obtained. On the contrary, when the occupation ratio of the concave portion 4 is less than the above lower limit, the total area of the planar view region of the concave portion 4 is insufficient, for example, the effect of escaping the oil in the concave portion 4 is insufficient and the grip force is sufficient. May not be obtained.

The average thickness t1 (see FIG. 2) of the recesses 4 in the uneven shape is 50 μm or more and 500 μm or less. The upper limit of the average thickness t1 of the recess 4 is more preferably 350 μm. On the other hand, the lower limit of the average thickness t1 of the recess 4 is more preferably 80 μm. When the average thickness t1 of the recess 4 exceeds the upper limit, the covering layer 2 becomes too thick, and the flexibility of the anti-skid glove may be insufficient. On the other hand, when the average thickness t1 of the concave portion 4 is less than the lower limit, the covering layer 2 is easily torn at the base of the convex portion 3, and the strength of the covering layer 2 may be reduced. The average thickness t1 of the concave portion 4 is determined by observing the cross section of the palm region of the non-slip glove using a scanning electron microscope (for example, “JSM-6060A” manufactured by JEOL Ltd.). It is an average value of values obtained by measuring five arbitrary locations (excluding specific locations such as the end of the palm) with respect to the distance from the inner surface to the bottom surface of the recess 4.

The upper limit of the average width w (see FIG. 2) of the concave portion 4 in the concave and convex shape is 15 mm, and more preferably 10 mm. On the other hand, as a minimum of average width w of the above-mentioned crevice 4, it is 100 micrometers and 500 micrometers is more preferred. When the average width w of the concave portion 4 exceeds the upper limit, the total area of the convex portions 3 in the concave / convex shape forming region is reduced, and the anti-skid effect of the anti-skid gloves may not be sufficiently obtained. On the contrary, when the average width w of the concave portion 4 is less than the lower limit, the width of the groove is narrowed and the effect of escaping oil is lowered, so that the antiskid effect may not be sufficiently obtained. The “average width of the recess” means an average value of the width of the recess in a plan view region. For example, using a scanning electron microscope (for example, “JSM-6060A” of JEOL Ltd.) It is an average value of values obtained by observing a cross section of the palm region and measuring any five locations with respect to the width of the planar view region of the recess.

Further, the upper limit of the unevenness difference h (the difference between the average thickness t1 of the concave portion 4 and the average thickness t2 of the convex portion 3) of the concave-convex shape is preferably 0.7 mm, and more preferably 0.6 mm. On the other hand, the lower limit of the unevenness difference h is preferably 0.15 mm, and more preferably 0.2 mm. When the unevenness difference h exceeds the upper limit, the convex portion 3 becomes too high, and the convex portion 3 may be easily detached. In addition, since the convex portion 3 is easily elastically deformed, a load is applied to the base of the convex portion 3, so that the strength of the covering layer 2 may be reduced. On the contrary, when the unevenness difference h is less than the lower limit, the effect of escaping oil is weakened, and there is a possibility that sufficient grip force cannot be obtained. The average thickness t2 of the convex portion 3 is an average value obtained by measuring the distance from the innermost surface of the coating layer 2 to the upper bottom surface of the convex portion 3 by the same method as the average thickness t1 of the concave portion 4. It is.

Also, the upper limit of the ratio (t1 / t2) of the average thickness t1 of the concave portion 4 to the average thickness t2 of the convex portion 3 is preferably 70%, and more preferably 60%. On the other hand, the lower limit of the ratio of the average thickness t1 of the concave portion 4 to the average thickness t2 of the convex portion 3 is preferably 10%, and more preferably 15%. When the ratio of the average thickness t1 of the concave portion 4 to the average thickness t2 of the convex portion 3 exceeds the upper limit, there is a possibility that a grip force or flexibility cannot be sufficiently obtained. Conversely, if the ratio of the average thickness t1 of the concave portion 4 to the average thickness t2 of the convex portion 3 is less than the lower limit, the convex portion 3 may be easily detached or the coating layer 2 may be easily torn. is there.

Further, the upper limit of the difference in the thickness t2 between the adjacent convex portions 3 is preferably 0.3 mm. The anti-skid glove is flexible and absorbs the difference in the thickness t2 between the adjacent convex portions 3 so that the upper bottom surface of the convex portion 3 contacts the grasped object. When the difference exceeds the above upper limit, the lower convex portion 3 becomes difficult to contact the gripped object, and the grip force may not be sufficiently obtained.

<Manufacturing method of non-slip gloves>
Although the said anti-skid glove can be manufactured by various methods, the example is shown below.

First, the glove body 1 is covered with a three-dimensional hand mold for dipping, and a part of the palm or fingertip or the entire glove body 1 is dipped in a coagulant. Examples of the coagulant include sodium chloride, calcium chloride, acetic acid, calcium nitrate, and citric acid. You may use these individually or in combination of 2 or more types. Among these, calcium nitrate is preferable because a coagulation effect can be obtained in a short time. Examples of the coagulant solvent include methanol and water. Then, after sufficiently dripping the coagulant, the palm region, a part of the fingertip or the entire glove body 1 is immersed in the rubber composition or the resin composition to form the coating layer 2. By using this method using a coagulant, it becomes difficult for the coating layer 2 to penetrate to the innermost surface of the glove body 1, and the feel of the inner surface of the glove can be improved. Thereafter, the hand mold covered with the glove body 1 is dried at a temperature of 60 ° C. to 95 ° C. for 3 to 10 minutes, so that the coating layer 2 is in a semi-crosslinked or semi-vulcanized state. Alternatively, the coating layer 2 may be gelled by being immersed again in the coagulant. Thus, the production time of a non-slip glove can be shortened by gelatinizing the coating layer 2. The coating layer 2 may be completely vulcanized by heating at a temperature of 120 ° C. to 140 ° C. for 20 to 60 minutes. This method is not preferable because the pressure needs to be increased and a load is applied to the gloves.

Next, the glove body 1 is removed from the three-dimensional hand mold and covered with a flat mold, and a concave / convex shape is formed on the outer surface of the glove by pressing it from above the palm area with the concave / convex plate. This pressing is preferably performed under the conditions of a pressing pressure of 0.1 to 10 MPa and a pressing time of 1 second to 20 minutes. Moreover, it is preferable not to perform this press on the nail region 5 and the finger crotch region 6. Here, when pressing the glove, it is preferable to press while heating to 60 to 250 ° C., such as pressing the uneven plate. By pressing while heating, an uneven shape is easily formed on the outer surface of the glove. In addition, you may perform formation of the coating layer 2, and a press as a series of processes using the same hand mold, without changing a hand mold.

After pressing, put the glove on a hand shape that is close to the hand of a person with the thumb inside, and cure (vulcanize or crosslink) at 90 to 150 ° C for 10 to 60 minutes. Type. For example, a process of sewing a hook-and-loop fastener for preventing misalignment may be performed as necessary after release.

<Advantages>
Since the said anti-skid glove is provided with the coating layer 2 which coat | covers at least one part of the outer surface of the palm area | region of the glove main body 1, it shows the outstanding anti-slipping effect. Further, since the coating layer 2 is composed of a non-foamed rubber composition or a non-foamed resin composition, there is almost no bubble other than the foam that is accidentally bitten during coating, and the bubble ratio is further reduced by pressing. In addition, since the coating layer 2 is firmly fixed to the glove body 1, the anti-skid glove is excellent in wear resistance. Furthermore, since the average thickness of the recessed part 4 in the uneven | corrugated shape by press work is more than the said minimum, it can prevent that the glove body 1 is exposed from the recessed part 4 at the time of wear, and durability of the said non-slip glove improves. Moreover, since the average thickness of the said recessed part 4 is below the said upper limit, the recessed part 4 becomes a crease and it is easy to bend, and the said anti-skid glove exhibits favorable softness | flexibility. In addition, since the average width of the concave portion 4 is within the above range, the concave portion 4 provides an effect of oiling and escaping, and the anti-skid glove is excellent in gripping force. In addition, since the coating layer 2 is composed of one layer, the strength is also excellent. Moreover, since the coating layer 2 has a concavo-convex shape, the pattern due to the concavo-convex shape becomes thin when wear of the anti-skid glove progresses, and therefore the concavo-convex shape is used as an indicator of glove wear. Can prevent the use of gloves when the anti-slip effect is reduced.

[Other Embodiments]
The present invention is not limited to the above-described embodiment, and can be implemented in a mode in which various changes and improvements are made in addition to the above-described mode. In the above embodiment, in the configuration shown in FIG. 2, the coating layer 2 impregnates the outer surface side of the glove body 1, but the degree of impregnation into the glove body may be changed. For example, the coating layer may be impregnated from the center in the thickness direction inside the glove body to the inside.

In the above embodiment, the covering layer 2 covers the palm region of the glove body 1, but it may also cover the back side region of the glove body. By forming a covering layer also in the area on the back side of the hand, the protection function of the area on the back side of the anti-skid glove can be improved.

Although the shape of one convex part 3 which comprises the uneven | corrugated shape of the said embodiment was substantially hexagonal shape, it is set as regular hexagonal shape, for example, and it is set as the structure (honeycomb shape) which arranges the convex part at equal intervals in the same direction. Also good. Further, the shape of one convex portion 3 may be a polygonal shape other than an elliptical shape or a hexagonal shape.

These concavo-convex shapes are not limited to the entire palm region, and may be applied to arbitrary portions, and may be combined with a plurality of concavo-convex shapes without being limited to one type of concavo-convex shape. Flexibility can also be obtained by forming and arranging convex portions in this way. In particular, a structure having a relatively large number of grooves in the direction perpendicular to the middle finger direction is preferable because of easy bending of the finger.

Further, for example, as shown in FIG. 6A, the concave portion 4 has a square shape, and a direction parallel to the middle finger direction A over the entire palm region of the glove body 1 excluding a part (such as the nail region 5 and the finger crotch region 6). A plurality of recesses 4 may be arranged in a lattice pattern in the direction perpendicular to the middle finger direction A. In this case, portions other than the concave portions 4 arranged in a lattice form become the convex portions 3.

Furthermore, as another uneven | corrugated shape, as shown in FIG.6 (b), the convex part 3 and the recessed part 4 are alternately in the middle finger direction A (straight line direction which connects the base part of the glove body 1 and the middle finger). You may arrange | position in stripe form. The direction of the stripes is not particularly limited, but for example, it may be substantially the same as the direction that makes the finger easy to bend. By making the direction of the stripes substantially coincide with the direction that makes the finger easy to bend, it becomes easier to follow the movement of the palm, and higher flexibility is exhibited.

In addition, complicated irregularities may be formed by raising a pattern (knitting pattern or the like) previously formed on the glove body 1 to the upper surface of the convex portion by pressing. Thus, by raising the pattern formed on the glove body 1, grip properties and design properties are improved.

Also, the indicator function can be emphasized by making the cross-sectional shape of the concavo-convex convex portion stepped.

Hereinafter, the present invention will be described in more detail with reference to examples and comparative examples, but the present invention is not limited to the following examples.

[Example 1]
The metal three-dimensional hand mold was covered with a seamless glove knitted with 311 dtex wooly nylon using a 13 gauge knitting machine, and heated in a 70 ° C. atmosphere. Next, after immersing the seamless glove in a coagulant bath composed of 100 parts by mass of methanol and 1 part by mass of calcium nitrate, the seamless glove just before dipping the rubber compounding solution is allowed to stand for 30 seconds at a room temperature of 30-40 ° C. The surface temperature was adjusted to 40 ° C. This hand mold was dipped in a rubber compounding bath described later, and rested in that state for 4 seconds, then pulled up from the bath and dried at 75 ° C. for 10 minutes.

Subsequently, the gloves were removed from the three-dimensional hand mold, re-covered on a metal flat mold, and pressed using a concavo-convex plate at 120 ° C. and a pressure of 1.0 MPa for 10 minutes. Here, in order to obtain a glove in which square-shaped concave portions are arranged in a lattice shape as shown in FIG. 6A, the concavo-convex plate has a convex portion (a concave portion of the glove) in a square shape and is arranged in a lattice shape. In addition, the average width of the convex portions of the concave / convex plate (average width w of the concave portions of the glove) is set to 2 mm so that the total area ratio of the concave portions in the concave / convex shape forming region of the glove is 44%. (Average width of the convex part of the glove) was 1 mm. The unevenness difference of the uneven plate (the unevenness difference h of the uneven shape of the glove) was 0.25 mm.

After that, the gloves were put on a three-dimensional hand mold and heated at 110 ° C. for 40 minutes, and the gloves were removed from the hand mold to obtain a non-slip glove.

[Measurement]
The dynamic friction coefficient, grip force, wear resistance and flexibility were evaluated for all or part of Examples 1 to 18 and Comparative Examples 1 and 2.

<Dynamic friction coefficient>
The dynamic friction coefficient was measured under two conditions of a DRY condition and an OIL condition using a 20 × 50 mm test piece from the portion where the uneven shape was formed. As a measurement method under the DRY condition, “Universal testing machine Autograph ASG-J” manufactured by Shimadzu Corporation is used as a testing machine so that the contact surface (20 × 20 mm) is hidden in the friction element (437 g). The test piece was attached, and a traveling distance of 130 mm was run at 150 mm / min on a horizontally placed stainless steel plate (the surface was buffed), and the frictional force between them was measured. The dynamic friction coefficient was calculated from the average frictional force from the position of 30 mm from the start of tension to the position of 20 mm before stopping. The measurement environment is a temperature of 20 ° C. ± 2 ° C. and a relative humidity of 40% ± 10%. In the measurement under the OIL condition, the measurement was performed under the same conditions as the DRY condition except that 0.5 ml of cutting oil (20-fold diluted “Emulcut FA500KS” manufactured by Kyodo Yushi Co., Ltd.) was applied on the stainless steel plate. In addition, it evaluated that the antiskid effect was so high that the value of a dynamic friction coefficient was high. Specifically, in OIL conditions, a five-step evaluation was performed based on the following evaluation criteria. The results are shown in Table 1.

(Criteria for dynamic friction coefficient evaluation)
A: Dynamic friction coefficient is 0.65 or more B: Dynamic friction coefficient is 0.60 or more and less than 0.65 C: Dynamic friction coefficient is 0.55 or more and less than 0.60 D: Dynamic friction coefficient is 0.50 or more and 0.00. Less than 55 E: Dynamic friction coefficient is less than 0.50

<Grip strength sensory evaluation>
Ten subjects were put on gloves and their impressions when holding a stainless steel rod (diameter 30 mm, length 200 mm) with cutting oil were evaluated in the following five stages. Table 1 shows the average of the evaluation results.

(Grip strength evaluation criteria)
A: Very high grip and does not slide at all B: High grip and hardly slips C: A little grip and slippery D: Cannot be said E: Low grip and slip

<Abrasion resistance>
The abrasion resistance test was performed in accordance with the European unified standard EN 388: 2003 “6.1 Abbreviation resistance of Protective gloves against mechanical risks”, and the number of frictions was counted. The abrasion resistance test was performed under two conditions of DRY conditions and OIL conditions. The tester is a tester Nu-Martindale determined by EN-ISO-12947-1, and the wear paper is Klingsport PL31B 180 grit. One test piece was collected per glove. The location where the test piece was collected is a palm region in which an uneven shape is formed. In addition, the test environment was a temperature of 20 ± 2 ° C. and a relative humidity of 40 ± 10%. Under the OIL condition, the coating layer surface side was further immersed for 30 minutes in white kerosene, and then the oil adhering to the surface was wiped off. The test piece was used for testing. In addition, it has shown that the frequency | count of friction until it breaks, so that a numerical value becomes large, and it means that abrasion resistance is high. The results are shown in Table 1. In Table 1, “1000 <” indicates that the test piece was not torn after 1000 wears.

<Flexibility sensory evaluation>
Ten subjects were asked to wear the gloves of Example 1, Example 16, and Example 17, and their fingers were bent and stretched. The force applied to the hand at that time was evaluated based on the following evaluation criteria, and the average was obtained. The results are shown in Table 1.

(Standard for flexibility evaluation)
A: Very good flexibility and extremely good bending and stretching of fingers B: Excellent flexibility and good bending and stretching of fingers C: Flexible and does not interfere with bending and stretching of fingers D: Neither can be said E: Flexible Inability to flex and stretch fingers

In Table 1, “material” refers to the main component of the rubber composition or resin composition constituting the coating layer, and “ratio of the average thickness of the projections and depressions” refers to the above-described depressions with respect to the average thickness of the projections. The average thickness ratio (t1 / t2) is shown.

From the results shown in Table 1, the antiskid gloves of Examples 1 to 17 are superior in antiskid effect, wear resistance and flexibility as compared with the gloves of Comparative Examples 1 and 2. The coating layer is composed of a non-foamed rubber composition or a resin composition, and a concave / convex shape is formed on the coating layer in the palm region by pressing, and the average thickness of the concave portions in the concave / convex shape is 50 μm or more and 500 μm or less. It can be seen that the anti-slip effect, wear resistance and flexibility are excellent.

Looking at the material of the coating layer in Table 1, compared with Example 1 and Example 18, when the material (main component) of the coating layer is an acrylonitrile-butadiene copolymer, the wear resistance is further increased. I understand that.

As for the total area ratio of the recesses in Table 1, since the evaluation results of the grip force sensory evaluation are higher in Examples 1 and 5 than in Examples 1 to 8, the total area ratio of the recesses is constant. It turns out that the grip power of a non-slip glove further increases by setting it as the range of.

Looking at the average unevenness in Table 1, comparing Example 1 and Examples 9-15, the dynamic friction coefficient under the OIL condition is maximum in Example 1 and Example 12, so the average unevenness is It turns out that the slip prevention effect in the oil work etc. of the said non-slip glove further increases by setting it as a fixed range.

<Examination of coagulation effect by calcium nitrate>
After treating the seamless glove on the flat mold in the same manner as in Example 1 until the seamless glove was pulled out of the rubber compound bath, it was immersed in a coagulant bath of 10% calcium nitrate aqueous solution instead of drying at 75 ° C. for 10 minutes. The solution was hardened and pressed using the same relief plate as in Example 1 at room temperature and a pressure of 1.0 MPa for 10 minutes. Thereafter, the gloves were put on the three-dimensional hand mold and heated at 110 ° C. for 40 minutes, and the gloves were removed from the hand mold to obtain a non-slip glove. The obtained gloves were excellent in antiskid effect and abrasion resistance. Thus, it turns out that the production time of a non-slip glove can be shortened by gelatinizing a rubber compounding liquid with a coagulant (calcium nitrate) instead of drying before pressing.

<Examination of cross-sectional shape of convex part>
By using an uneven plate having a shape in which the central portion of the bottom surface of the concave portion is rounded and recessed when hot pressing is performed, a shape in which the central portion of the convex portion surface bulges in a round shape (the cross-sectional shape of the convex portion shown in FIG. 5A) ) Was obtained. It was confirmed that the non-slip glove having the convex shape was a glove having a high grip force particularly in oil work as compared with the glove of Example 1.

In addition, by using a concavo-convex plate having a shape in which the width of the upper surface side and the bottom surface side of the concave portion is both narrow and the width of the intermediate portion is wide when hot pressing, both the width of the convex body side and the upper bottom surface side are narrow. A glove having a shape with a wide intermediate portion (a cross-sectional shape of the convex portion shown in FIG. 5B) was obtained. It was confirmed that the non-slip glove having the convex shape is a glove having a high grip force with respect to the gripped object and a high followability to the gripped object, for example, during oil work, compared with the glove of Example 1.

Furthermore, when pressing, by using the surface of the concavo-convex plate of Example 1 with the upper and bottom surfaces of the convex portion and the bottom surface of the concave portion made constant, the concavo-convex plate difference of 1.0 mm is used. A non-slip glove was obtained. The convex part of this non-slip glove had a shape in which the central part of the surface was depressed (cross-sectional shape of the convex part shown in FIG. 5C). It was confirmed that this non-slip glove was a glove having higher followability to the gripping object than the glove of Example 1.

As described above, the antiskid gloves of the present invention having excellent antiskid effect, wear resistance, strength and flexibility are worn by an operator at a factory, for example, or worn by a worker during transportation work, It can be used for various purposes, such as being worn by a driver.
