Description

[Technical Field]

[0001] The present invention relates to a cut-resistant glove with heat retention properties. [Background technology]

[0002] When working with sharp objects such as steel plates, glass, or blades, improper handling can result in cut injuries. A cut is an injury caused by a sharp object cutting the skin or tissue of the body, i.e., a cut. One countermeasure is to wear cut-resistant gloves when working with sharp objects. Cut resistance refers to the property of being difficult to cut so that the body can be protected from cuts. Furthermore, when working with sharp objects in a low-temperature environment, it is desirable that the gloves worn be not only cut-resistant but also warm.

[0003] For example, Patent Document 1 discloses a cut-resistant, highly warm glove containing a high-performance fiber having a tensile modulus of 300 cN / dtex or more and a polyphenylene sulfide fiber (hereinafter also referred to as "PPS fiber"). In the gloves described in Patent Document 1, a para-aramid fiber is preferably used as the high-performance fiber, and a fiber made of a polymer containing phenylene sulfide structural units in which approximately 90% or more of the structural units are -(C6H4-S)- is preferably used as the PPS fiber. The gloves described in Patent Document 1 are preferably constructed such that the surface of the glove is primarily made of the high-performance fiber and the back of the glove is primarily made of the PPS fiber, since this improves the warmth of the inside of the glove and the cut resistance of the surface of the glove. Furthermore, in order to minimize the deterioration of workability and mobility, the gloves are preferably knitted on a knitting machine of 10 gauge or more and have a fabric weight of approximately 350 g / m2. 2 Patent Document 1 explains that the following cut-resistant and highly insulating gloves are preferred.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-306817 Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, when trying to improve the cut resistance of gloves, one possible improvement is to change the yarn used in the glove fabric to a yarn with excellent cut resistance. Another possible improvement is to increase the amount of cut-resistant yarn used per unit volume of the glove fabric. However, cut-resistant yarn has a hard feel. Therefore, gloves improved in this way have the problem that when wearing the gloves, the hard and itchy feel caused by the cut-resistant yarn increases, which is likely to be uncomfortable for the wearer.

[0006] Therefore, an object of the present invention is to provide a cut-resistant glove that combines cut resistance, heat retention, and a soft feel when worn. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, one embodiment of the cut-resistant glove is a cut-resistant glove having a pile knit fabric, wherein the pile knit fabric is a knit fabric in which multiple yarns including a cut-resistant ground yarn and a pile yarn are pile-knitted at a gauge of less than 10, and the pile yarn forms multiple loops on the back of the pile knit fabric that are pulled out longer than the ground yarn.

[0008] According to this cut-resistant glove, the pile knit fabric is knitted at a gauge of less than 10, which makes it thicker than knit fabrics knitted at a gauge of 10 or more, and therefore more likely to exhibit cut resistance. Furthermore, the pile yarn forms multiple loops on the back of the pile knit fabric, making it easier for the multiple loops to be interposed between the ground yarn of the pile knit fabric and the wearer's hand when the cut-resistant glove is worn. In other words, the presence of the multiple loops reduces the likelihood of the wearer's hand coming into contact with the ground yarn contained in the pile knit fabric. Therefore, the wearer is less likely to feel the stiff, prickly sensation caused by the ground yarn and is more likely to feel the soft sensation caused by the multiple loops. Furthermore, the multiple loops facilitate air retention on the surface of the wearer's hand, providing warmth. [Effects of the Invention]

[0009] As described above, according to the present invention, it is possible to provide cut-resistant gloves that combine cut resistance, heat retention, and a soft feel when worn. [Brief explanation of the drawings]

[0011] Hereinafter, several embodiments of the present invention will be described with reference to the drawings. Components common to each drawing are designated by the same reference numerals. The size, dimensions, positional relationship, etc. of each component shown in the drawings are merely illustrative and are not limited to those shown in the drawings.

[0012] 1A and 1B illustrate a cut-resistant glove 10a (hereinafter also referred to as "glove 10a") according to one embodiment. The glove 10a includes a glove body 20 made of at least one pile knit fabric 25. The at least one pile knit fabric 25 may be a single pile knit fabric 25, or may be a plurality of pile knit fabrics each including a pile knit fabric 25.

[0013] The glove body 20 is knitted into a glove shape using at least one pile knit fabric 25, and is a textile product that is arranged to cover the wearer's hand when the glove 10a is worn. The glove body 20 includes a bag-shaped main bag portion 21 that is arranged to cover the back and palm of the wearer's hand when the glove 10a is worn. The main bag portion 21 includes a back portion 21a (FIG. 1A) that is arranged to cover the back of the wearer's hand, and a palm portion 21b (FIG. 1B) that is arranged to cover the wearer's palm. In addition to the main bag portion 21, the glove 10a may include finger bag portions 22 that extend from one end of the main bag portion 21 and are arranged to cover the wearer's fingers, and a hem portion 23 that extends from the other end of the main bag portion 21 and are arranged to cover the wearer's wrist. The finger stall 22 may include a first finger stall 22a arranged to cover the wearer's thumb, a second finger stall 22b arranged to cover the index finger, a third finger stall 22c arranged to cover the middle finger, a fourth finger stall 22d arranged to cover the ring finger, and a fifth finger stall 22e arranged to cover the little finger. These portions (21 to 23) of the glove body 20 may be knitted together without a seam, for example. In other words, the glove body 20 may be knitted into a glove shape using a single terry knit fabric 25. Alternatively, these portions (21 to 23) of the glove body 20 may be sewn together to form the entire glove body 20. In other words, the glove body 20 may be formed into a glove shape by sewing together the terry knit fabric for knitting the main pocket 21 and other terry knit fabrics for knitting the other portions (22, 23).

[0014] The shape of the glove body 20 may be any shape that allows a person to wear the glove body 20 to perform some kind of manual work, and is not limited to the glove shape exemplified in Figures 1A and 1B. As another example of a shape, the glove body may be mitten-shaped. When the glove body is mitten-shaped, it may have a modified and integrated shape compared to the glove-shaped glove body 20 exemplified in Figures 1A and 1B, for example, so that the second finger stall portion 22b to the fifth finger stall portion 22e form a single bag-like shape, or so that the third finger stall portion 22c to the fifth finger stall portion 22e form a single bag-like shape.

[0015] The pile knit fabric 25 is a knitted fabric in which multiple yarns, including a ground yarn and a pile yarn, are pile-knitted. The pile knit fabric 25 is a type of plain knitting structure, and has multiple loops (multiple bent loops) on the surface of the knitted fabric, each loop being ring-shaped. The ground yarn is a yarn that forms the basis of the pile knit fabric 25, and is a constituent unit of a cut-resistant yarn or a combination of two or more yarns including a cut-resistant yarn. When knitting the pile knit fabric 25, for example, a single cut-resistant yarn may be used as the ground yarn as is, or a set of multiple yarns including at least one cut-resistant yarn may be used as the ground yarn. The pile yarn is a yarn that constitutes the pile knit fabric 25 together with the ground yarn, or a yarn that is a constituent unit of a combination of two or more yarns including this yarn, so as to form multiple loops that are drawn out longer than the ground yarn in the purl stitch 25b (FIG. 1A) of the pile knit fabric 25, as exemplified in FIGS. 2A and 2B. For example, a single yarn having flexibility capable of forming the plurality of loops may be used as the pile yarn as is, or a set of multiple yarns each having such flexibility may be used as the pile yarn.

[0016] The back stitch 25b of the pile knit fabric 25 is arranged on the inside of the glove body 20 (the side that comes into contact with the wearer's hand when the glove 10a is worn) and is a portion constituted by a thermal insulation layer 252 formed by multiple loops of pile yarn drawn out longer than the ground yarn. In other words, the thermal insulation layer 252 is a layer of the pile knit fabric 25 that is constituted by multiple loops of pile yarn and does not contain ground yarn. For example, the thermal insulation layer 252 may be formed continuously on at least a part of the surface of the inside of the glove body 20 (the side that comes into contact with the wearer's hand when the glove 10a is worn), but it is preferably formed over the entire inside surface of the glove body 20. The face stitch 25a of the pile knit fabric 25 is arranged on the outside of the glove body 20 (the side that does not come into contact with the wearer's hand when the glove 10a is worn) and is a portion constituted by a knitted fabric layer 251 in which the ground yarn and the pile yarn are entangled. That is, the knitted fabric layer 251 is a basic layer including ground yarns and pile yarns in the pile knit fabric 25. The knitted fabric layer 251 may be formed continuously on at least a part of the outer surface of the glove body 20 (the side that does not come into contact with the wearer's hand when the glove 10a is worn), but it is preferably formed over the entire outer surface of the glove body 20.

[0017] The ground yarn is a yarn that has cut resistance due to the inclusion of at least one cut-resistant yarn. The at least one cut-resistant yarn may be, for example, a single cut-resistant yarn, but from the perspective of further improving cut resistance, it is preferable that the ground yarn be two or more cut-resistant yarns including this single cut-resistant yarn. In other words, the ground yarn may be, for example, a yarn including a single cut-resistant yarn, but it is preferable that the ground yarn be a yarn including two or more cut-resistant yarns including this single cut-resistant yarn. The cut-resistant yarn included in the ground yarn may be, for example, a spun yarn including multiple inorganic staple fibers. Alternatively, the cut-resistant yarn included in the ground yarn may preferably be, for example, a monofilament yarn including one type of long fiber selected from the group consisting of synthetic resin fibers containing inorganic staple fibers, synthetic resin fibers containing inorganic particles, metal fibers, long glass fibers, and carbon fibers, or a multifilament yarn including multiple long fibers of at least one type of long fiber. In other words, the long fibers of metal fibers can also be referred to as metal wires.

[0018] From the viewpoint of further enhancing cut resistance, the fineness of the at least one cut-resistant yarn may be, for example, 30 dtex or more, 50 dtex or more, or 80 dtex or more. Furthermore, from the viewpoint of preventing the feel of the pile knitted fabric 25 from becoming too stiff, the fineness of the at least one cut-resistant yarn may be, for example, 400 dtex or less, 250 dtex or less, or 200 dtex or less. Note that, in this specification, "fineness" refers to the total fineness of two or more yarns when the object for which the numerical value of fineness is indicated is composed of two or more yarns. For example, when the at least one cut-resistant yarn is composed of multiple cut-resistant yarns, the value of the "fineness of at least one cut-resistant yarn" described above is the total fineness of the cut-resistant yarns included in the multiple cut-resistant yarns. Furthermore, the fineness value in this specification is a value calculated by winding 100 m of a sample yarn using a known measuring machine, measuring its mass, and multiplying the measured mass by 100 to obtain the mass per 10,000 m (i.e., fineness (dtex)). In this specification, when expressing the thickness of a spun yarn, the fineness value of the spun yarn is described using the unit dtex, rather than cotton count or metric count.

[0019] Examples of metal fibers include long fibers such as stainless steel fibers or tungsten fibers. From the viewpoint of further improving cut resistance, the fiber diameter (diameter) of a single metal fiber may be, for example, 10 μm or more or 20 μm or more, and from the viewpoint of preventing the pile knitted fabric 25 from becoming too hard, it may be, for example, 50 μm or less or 40 μm or less. From the viewpoint of preventing the tactile feel of the pile knitted fabric 25 from becoming too hard, the ground yarn may be, for example, a yarn containing one metal fiber or two to three metal fibers as a cut-resistant yarn, but is preferably a yarn containing one metal fiber or two metal fibers.

[0020] Glass fibers are long fibers that can be formed, for example, by extruding fused silica-based glass or other compounded glass into thin strands or filaments. Glass fibers are available from glass fiber manufacturers, such as B&W Fiber Glass Inc. To further enhance cut resistance, the glass fibers are preferably long fibers made of glass with a Mohs hardness of 3.0 or higher. The at least one cut-resistant yarn may be, for example, a single multifilament yarn made of a bundle of multiple glass fibers. Preferably, each multifilament yarn is a combination of two multifilament yarns, each made of a bundle of multiple glass fibers. The single yarn fineness of the multifilament yarn made of a bundle of multiple glass fibers may be, for example, 50 dtex or more or 80 dtex or more to further enhance cut resistance, or may be, for example, 250 dtex or less or 150 dtex or less to prevent the pile knit fabric 25 from becoming too stiff.

[0021] Synthetic fibers containing inorganic short fibers or inorganic particles are long fibers that can be produced by kneading inorganic short fibers or inorganic particles into synthetic fibers when melt-kneading and extruding a resin to spin the synthetic fibers. The amount of inorganic short fibers or inorganic particles added to the melt-kneaded resin is adjusted according to the desired level of cut resistance. Examples of inorganic short fibers include one or more short fibers selected from metal fibers, glass fibers, and carbon fibers, and glass fiber short fibers are preferred. The inorganic short fibers may be, for example, fibers that have been produced as inorganic long fibers and then shortened. Examples of inorganic particles that can be used include particles of silicon carbide, silicon nitride, boron carbide, or boron nitride.

[0022] From the viewpoint of further improving cut resistance, the ground yarn is preferably a composite yarn containing at least one cut-resistant yarn and at least one reinforcing yarn. In this composite yarn, the method of combining the at least one cut-resistant yarn and the at least one reinforcing yarn may be covering, twisting, or a combination of these. The at least one reinforcing yarn may be a single reinforcing yarn, or may be two or more reinforcing yarns including this single reinforcing yarn. From the viewpoint of further improving cut resistance and making it less likely that the hard, prickly feel caused by the cut-resistant yarn will become apparent, the ground yarn is preferably, for example, a covered yarn having at least one cut-resistant yarn as a core yarn and at least one reinforcing yarn as a sheath yarn. From a similar perspective, it is more preferable that the ground yarn is, for example, a double-covered yarn in which at least one cut-resistant yarn is used as a core yarn, one reinforcing yarn is used as a first sheath yarn, and another reinforcing yarn is used as a second sheath yarn, and the first sheath yarn is wound around the outer periphery of the covered yarn in which the core yarn is wound with the second sheath yarn.From a similar perspective, it is preferable that the ground yarn is, for example, a yarn in which any of the composite yarns exemplified here is combined with another composite yarn.

[0023] Although the reinforcing yarn does not fall under the category of the cut-resistant yarn (a monofilament yarn containing one type of long fiber selected from the group consisting of synthetic resin fibers containing inorganic short fibers, synthetic resin fibers containing inorganic particles, metal fibers, glass fibers, and carbon fibers, or a multifilament yarn containing multiple long fibers of at least one type of long fiber), it can improve the cut resistance of the ground yarn when used in combination with the cut-resistant yarn. Examples of the reinforcing yarn include yarns containing one or more fibers selected from the group consisting of para-aramid fibers (polyparaphenylene terephthalamide fibers), meta-aramid fibers, and ultra-high molecular weight polyethylene fibers. Examples of para-aramid fibers include commercially available fibers bearing registered trademarks such as Kevlar, Technora, Twaron, and Heracron. Examples of meta-aramid fibers include commercially available fibers bearing registered trademarks such as Nomex and Teijinconex. Examples of ultra-high molecular weight polyethylene fibers include commercially available fibers bearing registered trademarks such as Dyneema and Spectra.

[0024] The reinforcing yarn may be a spun yarn containing a plurality of staple fibers, a blended yarn containing two or more types of staple fibers, a filament yarn composed of long fibers, a blended yarn containing two or more types of filament yarn, or a yarn containing staple fibers and long fibers. From the viewpoint of further improving cut resistance, the fineness of at least one reinforcing yarn may be, for example, 100 dtex or more, 250 dtex or more, or 400 dtex or more, and preferably 500 dtex or more. From the viewpoint of preventing the pile knit fabric 25 from becoming too stiff, the fineness of at least one reinforcing yarn may be, for example, 1,500 dtex or less, 1,300 dtex or less, preferably 900 dtex or less, and more preferably 750 dtex or less.

[0025] The ground yarn may be, for example, one consisting of at least one cut-resistant yarn. For example, the ground yarn may be a yarn consisting of only one cut-resistant yarn, or two or more cut-resistant yarns. When the ground yarn is made of only two or more cut-resistant yarns, the ground yarn may be, for example, a two-ply yarn formed by twisting two cut-resistant yarns together, a triplet yarn formed by twisting three cut-resistant yarns together, or a drawn yarn formed by pulling two or more cut-resistant yarns together without twisting them together. Alternatively, the ground yarn may be, for example, one consisting of only at least one composite yarn. The at least one composite yarn may be a single composite yarn or two or more composite yarns. A composite yarn (each composite yarn included in two or more composite yarns) may be a combination of one cut-resistant yarn or two or more cut-resistant yarns and one reinforcing yarn or two or more reinforcing yarns, for example, by twisting, covering once, or covering twice or more times, or may be a combination of untwisted and paralleled yarns. When using a ground yarn consisting of only two or more composite yarns, the ground yarn may be, for example, a two-ply yarn formed by twisting two composite yarns together, a triplet yarn formed by twisting three composite yarns together, or a paralleled yarn formed by untwisted and paralleled two or more composite yarns. Alternatively, the ground yarn may include at least one cut-resistant yarn and at least one composite yarn. The ground yarn may be, for example, a combination of one cut-resistant yarn or two or more cut-resistant yarns and one composite yarn or two or more composite yarns, for example, by twisting or covering.

[0026] The ground yarn may be, for example, a composite yarn including at least one cut-resistant yarn and at least one auxiliary yarn. Alternatively, the ground yarn may be, for example, a composite yarn including at least one cut-resistant yarn, at least one reinforcing yarn, and at least one auxiliary yarn. The at least one auxiliary yarn may be a single auxiliary yarn, or two or more auxiliary yarns including this single auxiliary yarn. As the auxiliary yarn, a known flexible spun yarn or multifilament yarn may be used. For example, a spun yarn or filament yarn including plant fibers, animal fibers, regenerated fibers, or relatively soft synthetic fibers may be used. Preferably, a spun yarn or filament yarn including multiple polyester fibers may be used. Furthermore, from the viewpoint of imparting water-absorbing and quick-drying properties to the ground yarn, it is preferable to use, as the at least one auxiliary yarn, a drawn yarn formed by drawing and aligning two or more high-multipolyester yarns in an untwisted state, or a drawn yarn formed by drawing and aligning two or more nylon multifilament yarns in an untwisted state. It is also preferable to use a composite yarn that combines such a paralleled yarn (at least one auxiliary yarn) with at least one cut-resistant yarn as the ground yarn. High multi-polyester yarn is a multifilament yarn containing multiple polyester fibers, each of which is extremely fine and has a low single fiber fineness. In the pile knitted fabric 25, the auxiliary yarn contained in the ground yarn and the pile yarn described below may be made of the same material or different materials. In the pile knitted fabric 25, for example, a yarn made of the same material as the pile yarn described below may be used as an auxiliary yarn contained in the ground yarn, which is a separate yarn from the pile yarn, in combination with a cut-resistant yarn or a reinforcing yarn. The ground yarn may be, for example, a composite yarn in which a cut-resistant yarn, a reinforcing yarn, and an auxiliary yarn are twisted together. The ground yarn may be, for example, a covering yarn in which a combination of a cut-resistant yarn and a reinforcing yarn is used as a core material, and one or more auxiliary yarns are wrapped around the outer periphery of this core material as sheath yarns.The ground yarn is preferably a double-covered yarn, for example, using a cut-resistant yarn as a core yarn, a reinforcing yarn as a first sheath yarn wound around the outer periphery of this core yarn, and an auxiliary yarn as a second sheath yarn wound around the outer periphery of the covering yarn formed by this core yarn and the first sheath yarn.

[0027] The ground yarn may be, for example, a composite yarn C formed by using two bundled stainless steel wires (two bundled cut-resistant yarns) as a core material, a single spun yarn or filament yarn (a single reinforcing yarn) containing multiple aramid fibers as a sheath yarn, and wrapping the sheath yarn around the core material. Alternatively, the ground yarn may be, for example, a double-covered yarn D formed by using a single stainless steel wire (a single first cut-resistant yarn) as a core yarn, a single multifilament yarn (a single second cut-resistant yarn) containing multiple synthetic fibers, each of which contains inorganic particles, as a first sheath yarn, and a single spun yarn or a single multifilament yarn (a single auxiliary yarn) containing multiple polyester fibers as a second sheath yarn, and wrapping the first sheath yarn around the covering yarn, which in turn has the second sheath yarn wrapped around it. Alternatively, the ground yarn may be a pulled-along yarn E formed by, for example, pulling and aligning the one composite yarn C and at least one spun yarn or at least one multifilament yarn each containing a plurality of nylon fibers in an untwisted state. Alternatively, the ground yarn may be a two-fold yarn F formed by twisting together the one double-covered yarn D and another double-covered yarn D. Alternatively, the ground yarn may be a pulled-along yarn G formed by, for example, pulling and aligning the two-fold yarn F and at least one spun yarn or at least one multifilament yarn each containing a plurality of nylon fibers in an untwisted state.

[0028] As described above, the ground yarn may be composed of two or more yarns. In this case, the "fineness" of the ground yarn refers to the sum of the finenesses of the two or more yarns contained in the ground yarn, i.e., the total fineness. From the viewpoint of further improving cut resistance, the fineness (total fineness) of the ground yarn may be, for example, 150 dtex or more, 320 dtex or more, 480 dtex or more, and preferably 580 dtex or more. In this case, from the viewpoint of preventing the ground yarn from becoming too stiff, the fineness (total fineness) of the ground yarn may be, for example, 1,500 dtex or less, and preferably 1,300 dtex or less. From the same viewpoint, and also from the viewpoint of further increasing the flexibility of the knitted fabric 25, the fineness (total fineness) of the ground yarn may be, for example, 950 dtex or less, and preferably 800 dtex or less.

[0029] The pile yarn is a flexible yarn capable of forming multiple loops pulled out from the ground yarn on the back stitch 25b of the pile knit fabric 25 (i.e., the inner surface of the glove body 20) to a degree that minimizes contact between the ground yarn and the wearer's hand, or a yarn consisting of a combination of two or more flexible yarns. The pile yarn may be a single type of flexible yarn, or a composite yarn made up of two or more types of flexible yarns. Examples of such flexible yarns include spun yarns or filament yarns containing plant fibers, animal fibers, regenerated fibers, or relatively soft synthetic fibers. Examples of plant fibers include cotton and hemp. Examples of animal fibers include wool, cashmere, and alpaca. Examples of regenerated fibers include rayon. Examples of synthetic fibers, excluding hard fibers such as cut-resistant fibers, include acrylic, nylon, polyester, and polyurethane.

[0030] As shown in Figures 2A and 2B, in the purl stitch 25b of the pile knit fabric 25, the gaps between the loops formed by the pile yarn trap air on the surface of the wearer's hands and function as a thermal layer 252, providing insulation for the air. To further enhance the cold protection provided by the thermal layer 252, it is preferable to use a yarn selected from the group consisting of acrylic fiber, wool fiber, rayon fiber, and modified cross-section fiber as the flexible pile yarn, or a composite yarn combining two or more types of yarn selected from this group. Modified cross-section yarns are fibers with a unique cross-sectional shape that does not conform to the typical round cross-sectional shape, such as fibers with a cross-sectional shape or hollow fibers. Modified cross-section fibers can be made of acrylic resin or polyester resin. To achieve both warmth and versatility, it is even more preferable to use a filament yarn containing acrylic fiber as the flexible pile yarn. Alternatively, from the viewpoint of facilitating the formation of multiple loops by the pile yarn in the back stitch 25b of the pile knitted fabric 25 during the raising process, it is preferable to use a spun yarn as the pile yarn having the flexibility described above, and it is even more preferable to use a spun yarn composed of multiple wool fibers or multiple acrylic fibers.

[0031] From the viewpoint of increasing the bulkiness of the thermal layer 252, thereby improving the cold protection performance, and further preventing contact between the ground yarn and the wearer's hands, it is preferable to use, as the pile yarn, a yarn comprising a two-ply yarn formed by twisting two single yarns, each of which has the flexibility described above as a single yarn. From the viewpoint of somewhat canceling out distortion caused by twisting and stabilizing the shape of each loop, the two-ply yarn contained in the pile yarn is preferably a two-ply yarn formed by twisting together two single yarns twisted in different directions. For example, a two-ply yarn formed by pulling together an S-twisted single yarn and a Z-twisted single yarn and twisting them together by Z-twisting is preferable. From the viewpoint of further increasing the bulkiness, etc. of the thermal layer 252, it is also preferable to use, as the pile yarn, a yarn comprising a plurality of two-ply yarns and formed by pulling together these multiple two-ply yarns. It is also preferable that the pile yarn fineness (total fineness) is, for example, 450 dtex or more, 500 dtex or more, and preferably 700 dtex or more, from the viewpoint of improving the cold protection performance by bulkiness. The pile yarn fineness (total fineness) is, for example, 2,000 dtex or less, preferably 1,500 dtex or less, and more preferably 1,200 dtex or less, from the viewpoint of facilitating knitting of the pile knitted fabric 25.

[0032] In order to ensure excellent heat retention of the heat-retaining layer 252 formed by multiple loops of pile yarn in the purl 25b of the pile knitted fabric 25, it is preferable that the single yarn that is the source of the pile yarn is a loosely twisted yarn. In other words, it can be said that it is preferable that the single yarn contained in the pile yarn in the pile knitted fabric 25 is a yarn that was loosely twisted when the pile knitted fabric 25 was knitted. When the pile yarn is loosely twisted, the single yarn is given a linear shape by the loose twist, which makes it easier for each loop contained in the multiple loops of pile yarn in the knitted pile knitted fabric 25 to be stable in an upright state, making it easier to brush the pile knitted fabric 25. "Loosely twisted" refers to a state in which the yarn is twisted at 500 tpm or less, and "tpm" here means twists per meter, or "twists / m." From the same viewpoint, when the pile yarn is loosely twisted, the single yarn is more preferably a yarn having a twist of 400 tpm or less, and even more preferably 350 tpm or less. From the viewpoint of preventing the pile yarn from becoming entangled with the ground yarn and falling out of the pile fabric 25, when the pile yarn is loosely twisted, the single yarn may be a yarn having a twist of, for example, 50 tpm or more, or 100 tpm or more, preferably 200 tpm or more, when the pile fabric 25 is knitted. Note that non-twist yarns that were not twisted when the pile fabric 25 was knitted are not included in the loosely twisted yarns. In addition, the values ​​of "tpm" and "twists / m" in this specification are obtained by observing a sample yarn under a microscope, measuring the length of the yarn required to twist the yarn once (m / twists 1 time) at multiple points on the yarn, and converting the arithmetic mean of the multiple measurements obtained into the number of times the yarn is twisted per 1.0 meter of yarn length (twists / m).

[0033] From the viewpoint of imparting a linear shape to the pile yarn and facilitating the stability of the plurality of loops forming the thermal insulation layer 252 in the pile knitted fabric 25 in a standing state on the knitted fabric structure layer 251, it is preferable to use a yarn formed by twisting together two or more single yarns as the pile yarn, and for example, it is preferable to use the two-ply yarn described above as the pile yarn, and it is also preferable to use a three-ply yarn formed by twisting together three single yarns. It is also preferable to use one type of yarn selected from the group consisting of the two-ply yarn and the three-ply yarn as the pile yarn, or a combination of two or more types of yarn selected from the group consisting of the two-ply yarn and the three-ply yarn.

[0034] From a similar perspective, when the pile yarn includes a two-ply yarn formed by twisting two single yarns together or a triple-ply yarn formed by twisting three single yarns together, it is preferable that when a thread-like segment is obtained by cutting a two-ply yarn or a triple-ply yarn into a length of 100 cm from the pile yarn before use in knitting the pile fabric 25 (for example, a pile yarn that has been unwound from a cone or cheese, etc., and is ready for use in knitting the pile fabric 25), and the thread-like segment is hung down while both ends of the thread-like segment are aligned and held so as not to untwist, the two single yarns in the two-ply yarn or the three single yarns in the triple-ply yarn are twisted together so that the number of intersections appearing in the hung thread-like segment (number of snarling intersections) is 6 or less. From a similar perspective, it is more preferable that the number of intersections appearing in this thread-like segment (number of snarling intersections) is 5 or less, and even more preferably 3 or less. In this specification, a filamentous segment cut to a length of 100 cm from a two-ply yarn is also referred to as a "two-ply yarn segment," and a filamentous segment cut to a length of 100 cm from a three-ply yarn is also referred to as a "three-ply yarn segment." FIG. 3A illustrates a filamentous segment 255a in which the number of crossings (number of snarling crossings) is two. FIG. 3B illustrates a filamentous segment 255b in which the number of crossings (number of snarling crossings) is ten. Each of the multiple arrows depicted in FIGS. 3A and 3B points to a location where one crossing appears. As shown in FIG. 3B, if the number of intersections appearing in the thread-like segment (number of snarling intersections) is 7 or more, the two or more single yarns constituting the pile yarn are twisted too much, making it difficult for the multiple loops formed by the pile yarn to stand on the knitted fabric layer (the multiple loops tend to lie flat on the knitted fabric layer), which may impair the heat retention and soft feel provided by the thermal layer, and is therefore not desirable.

[0035] In order to impart stiffness to the pile yarns in the same manner as in the loose twist described above and to ensure that the resulting thermal insulation layer 252 has excellent heat-retaining properties, the tensile strength of the pile yarns may be, for example, 1.40 cN / dtex or less, and preferably 1.30 cN / dtex or less. Furthermore, in order to prevent the pile yarns from becoming entangled with the ground yarns and slipping out of the pile knitted fabric 25, the tensile strength of the pile yarns may be, for example, 0.50 cN / dtex or more, and preferably 0.60 cN / dtex or more. The tensile strength values ​​in this specification are values ​​obtained by a measurement method using chucks in a tensile tester (Shimadzu Corporation, trade name: Tabletop Precision Universal Testing Machine, model: AGS-500NX) under the following conditions: a test piece length of 13 cm or more, room temperature of 25°C ± 2°C, a chuck distance of 60 mm, and a test speed of 100 mm / min.

[0036] The pile knit fabric 25 may be a knitted fabric that is pile knitted using a plurality of yarns including, in addition to the above-mentioned ground yarns and pile yarns, further yarns such as decorative yarns, as long as the amount is small enough to achieve the object of the present invention. From the viewpoint of efficiently enhancing the three elements of cut resistance, heat retention, and a soft feel when worn, the pile knit fabric 25 is preferably a knitted fabric that is pile knitted using a plurality of yarns consisting only of ground yarns and pile yarns. Furthermore, from the viewpoint of enhancing heat retention and a soft feel when worn, the ratio of the fineness of the pile yarn to the fineness of the ground yarn (fineness of pile yarn (dtex) / fineness of ground yarn (dtex)) may be, for example, 0.5 or more, preferably 0.9 or more, more preferably 1.3 or more, and even more preferably 1.6 or more. From the viewpoint of improving cut resistance, this ratio (pile yarn fineness (dtex) / ground yarn fineness (dtex)) may be, for example, 4.0 or less, preferably 3.0 or less, more preferably 2.5 or less, and even more preferably 2.0 or less.

[0037] The length of each of the plurality of loops formed by pulling out the pile yarn longer than the ground yarn in the back stitch 25b of the pile knitted fabric 25 may be, for example, 5.0 mm or more, preferably 6.0 mm or more, and more preferably 7.0 mm or more. With such a loop length, a heat-retaining layer 252 having a thickness of 1.5 mm or more is likely to be formed by the plurality of loops on the back stitch 25b side of the pile knitted fabric 25 relative to the ground yarn, which is preferable from the viewpoints of excellent heat-retaining effect and preventing the ground yarn from coming into contact with the wearer's hands. From the viewpoint of ease of knitting the pile knitted fabric 25, the length of each of the plurality of loops formed by the pile yarn in the back stitch 25b may be, for example, 15.0 mm or less, or 13.0 mm or less.

[0038] From the viewpoint of excellent heat retention and preventing the ground yarn from coming into contact with the wearer's hands, the thickness of the heat-retaining layer 252 formed by the plurality of loops of pile yarn on the back stitch 25b of the pile knitted fabric 25 may be, for example, 1.0 mm or more, preferably 1.3 mm or more, and more preferably 1.6 mm or more. From the viewpoint of a pile knitted fabric 25 that is easy to knit, the thickness of the heat-retaining layer 25 formed by the plurality of loops of pile yarn on the back stitch 25b of the pile knitted fabric 25 may be, for example, 4.0 mm or less, preferably 3.5 mm or less, and more preferably 3.0 mm or less.

[0039] The thickness of the thermal insulation layer 252 formed by the above-described multiple loops can be measured by observing a cross section of the pile knit fabric 25 cut in the thickness direction using a microscope at a magnification of, for example, 20 times. To explain this measurement method, FIGS. 2A and 2B each show an example of the same microscope image of a cross section of the pile knit fabric 25 cut in the thickness direction. To measure the thickness, as shown in FIGS. 2A and 2B, a sample for thickness measurement is prepared by attaching a piece of cardboard 27 with double-sided tape to the surface of the pile knit fabric 25 on the knit stitch 25a side, i.e., the surface on which the knitted fabric layer 251 composed of ground yarns and pile yarns is formed. Then, as shown in FIG. 2A, the thickness of the knitted fabric layer 251, where the ground yarns and pile yarns are entangled, of the pile knit fabric 25 is measured at multiple locations, and the arithmetic mean of the multiple thickness measurements obtained is defined as the thickness of the knitted fabric layer 251. 2B, the total thickness of the knitted fabric layer 251 and the thermal insulation layer 252 formed by multiple loops of pile yarn is measured at multiple locations, and the arithmetic mean value of the multiple thickness measurements is defined as the overall thickness of the pile knitted fabric 25. The thickness of the thermal insulation layer 252 formed by multiple loops of pile yarn is calculated by subtracting the thickness of the knitted fabric layer 251 (average 1.99 mm in the example shown in FIG. 2A) from the overall thickness of the pile knitted fabric 25 (average 4.06 mm in the example shown in FIG. 2B) (e.g., 4.06 mm - 1.99 mm = 2.07 mm). Note that care should be taken not to include the thickness of the cardboard 27 with double-sided tape when measuring the thickness.

[0040] In addition to having a thickness within any of the above-mentioned ranges, the thermal layer 252 preferably has multiple pile loops that are made up of pile yarns and are raised. A thermal layer 252 with multiple pile loops that are raised is preferable in that it further improves the softness of the inner surface of the glove body 20 compared to a non-raised layer, and also further improves the heat retention by increasing the amount of air retained in the thermal layer 252. The raising of the multiple pile loops can be performed by a method known to those skilled in the art. For example, the raising can be performed by manually or mechanically scratching the multiple pile loops with a brush.

[0041] Compared to a knitted fabric made only of cut-resistant ground yarns, the pile knitted fabric 25 does not have high overall cut resistance due to the inclusion of pile yarns. Instead, from the perspective of ensuring cut resistance by providing thickness to the pile knitted fabric 25, the pile knitted fabric 25 is a knitted fabric obtained by pile knitting multiple yarns including ground yarns and pile yarns to a gauge of less than 10, preferably 8 or less. For example, the pile knitted fabric 25 can be knitted using a knitting machine (preferably a glove knitting machine) designed to meet any gauge number condition within the range of 5 gauge or more and less than 10 gauge. Furthermore, the smaller the gauge number, the larger the stitches of the knitted pile knitted fabric 25, and the larger the thickness of the ground yarns and pile yarns that are compatible with the glove knitting machine. Therefore, from the perspective of more easily imparting a soft touch, the pile knitted fabric 25 is desirably a knitted fabric obtained by pile knitting multiple yarns including ground yarns and pile yarns to a gauge of, for example, 5 gauge or more, preferably 6 gauge or more.

[0042] From the viewpoint of further improving cut resistance, heat retention, and soft feel when worn, the density of the knitted pile knit fabric 25 is preferably 7 or more, more preferably 8 or more, in terms of the number of stitches per 1.0 inch (2.54 cm) width in the course direction. From the same viewpoint, the density of the knitted pile knit fabric 25 is preferably 10 or more, more preferably 13 or more, in terms of the number of stitches per 1.0 inch width in the wale direction. From the viewpoint of improving the flexibility of the glove body 20, the density of the knitted pile knit fabric 25 is preferably 15 or less, more preferably 12 or less, in terms of the number of stitches per 1.0 inch width in the course direction. From the same viewpoint, the density of the knitted pile knit fabric 25 is preferably 26 or less, more preferably 20 or less, in terms of the number of stitches per 1.0 inch width in the wale direction. In this specification, the value of the number of stitches shown as the density of the pile knit fabric 25 is a value measured from the appearance of a portion constituting the center of the palm portion 25a of the pile knit fabric 25 knitting the glove body 20. The wale direction is the warp direction of the pile knit fabric 25, and the course direction is the weft direction of the pile knit fabric 25.

[0043] As an index of the level of cut resistance of the glove 10a, the cut resistance level as an evaluation result of a TDM test in accordance with EN ISO 13997 can be used. When the glove 10a is used for applications where a certain level of cut resistance is sufficient, the cut resistance level of the pile knitted fabric 25 may be, for example, level C or higher, preferably level D or higher. When the glove 10a is used for applications where a relatively soft feel is more important than cut resistance, the cut resistance level of the pile knitted fabric 25 may be, for example, level D or lower. The TDM test is a method in which a test piece of the pile knitted fabric 25 is placed on a sample table arranged below a flat blade, and a load is applied from below to the sample table so as to push the sample table up toward the flat blade while the flat blade is slid in one direction, and the applied load and the distance the flat blade slid until the test piece penetrates are measured, and the cut resistance level of the test piece is evaluated from the measured values. The load on the flat blade estimated to be required to penetrate the test piece when sliding the flat blade 20 mm is 2 N or more for level A, 5 N or more for level B, 10 N or more for level C, 15 N or more for level D, 22 N or more for level E, and 30 N or more for level F.

[0044] The glove 10a having the glove body 20 described above has cut resistance due to the ground yarn, and can be used as a cut-resistant glove. The glove 10a also has heat retention due to the multiple loops of pile yarn, and is less likely to feel stiff due to the ground yarn. From this viewpoint, the glove 10a is suitable for use as a cut-resistant glove to be worn when handling sharp objects in cold environments. For example, the glove 10a is expected to be suitable for use as a work glove in mines, offshore oil fields, etc. in cold regions or during cold seasons.

[0045] From the viewpoint of further enhancing suitability as a work glove in cold environments compared to the above-described glove 10a, a cut-resistant glove 10b (hereinafter also referred to as "glove 10b") according to another embodiment, which will be described below mainly using Fig. 4A (back of hand side) and Fig. 4B (palm side), is preferred. Glove 10b comprises the above-described glove body 20 (see Figs. 1A and 1B) and outer glove 30 (Figs. 4A and 4B). The glove body 20 of glove 10b has the same configuration as the glove body 20 of the above-described glove 10a, and therefore the same description will not be repeated. The outer glove 30 of glove 10b is joined to the glove body 20 on the side of the stitch 25a of the pile knit fabric 25 of the glove body 20 so as to cover at least a portion of the glove body 20.

[0046] The outer glove 30 of the glove 10b is composed of at least one fabric 31. The at least one fabric 31 may be a single fabric 31 or multiple fabrics each including the fabric 31. The fabric 31 may be made from one or more types of yarn commonly used in glove manufacturing or by a known knitting method. The fabric 31 included in the outer glove 30 may be knitted using a glove knitting machine with a gauge of 10 to 26, for example, by a plain knitting or plating knitting method, but is not limited to this example. The fineness of one type of yarn or the total fineness of two or more types of yarn used to knit the fabric 31 included in the outer glove 30 may be any thickness usable on a glove knitting machine with a gauge of 10 to 26, for example, 50 dtex to 1,500 dtex, but is not limited to this example. The outer glove 30 may be made by cutting a textile fabric into a glove shape and sewing it.

[0047] The outer glove may be made of, for example, only the above-mentioned fabric 31. Alternatively, from the viewpoint of imparting anti-slip properties to the glove 10b, it is preferable that at least one resin coating layer 40 is laminated on at least a part of the outer surface of the fabric 31 of the outer glove 30 (the opposite side of the fabric from the inner side facing the glove body 20). The at least one resin coating layer 40 may be made of, for example, only one resin coating layer, but is preferably made of two or more resin coating layers.

[0048] 4A and 4B illustrate a glove 10b in which at least one resin coating layer 40 has a two-layer structure composed of a first resin coating layer 41 and a second resin coating layer 42. The first resin coating layer 41 is laminated on a portion of the outer surface of the fabric 31 of the outer glove 30. A second resin layer 42 is further laminated on a portion of the outer surface of the first resin coating layer 41. Specifically, FIGS. 4A and 4B illustrate a glove in which the first resin coating layer 41 is laminated on the entire portion of the outer glove 30 corresponding to the main pocket portion 21 and the finger pocket portion 22 of the glove body 20 illustrated in FIGS. 1A and 1B, and on a portion of the portion corresponding to the bottom hem portion 23. 4A and 4B, the second resin coating layer 42 is laminated only on a part of the portion 31a of the first resin coating layer 41 corresponding to the back of the hand 21a of the glove body 20 and on a part of the portion corresponding to the finger pocket 22 of the glove body 20 on the back side of the hand shown in FIG. 1A, whereas the second resin coating layer 42 is laminated on the entire area of ​​the portion 31b corresponding to the palm 21b, the entire area corresponding to the finger pocket 22, and on a part of the portion corresponding to the bottom hem 23 on the palm side shown in FIG. 1B. The position and shape of the at least one resin coating layer laminated on the outer glove fabric are not limited to the examples shown in FIGS. 4A and 4B.

[0049] The resin constituting the at least one resin coating layer 40 is not particularly limited as long as it is a resin of a material that can be used to form a resin coating layer in gloves such as conventional support-type gloves, etc. The resin constituting the at least one resin coating layer 40 may be, for example, rubber derived from latex.

[0050] To prevent the hands of a wearer of the glove 10b from becoming stuffy, at least one resin coating layer 40 of the glove 10b may include a visible portion composed solely of a porous resin coating layer made of foamed resin. Such a porous resin coating layer has excellent breathability and moisture absorption properties. Therefore, when a relatively large portion of the outer glove 30 is covered solely with such a porous resin coating layer, the hands of a wearer of the glove 10b are prevented from becoming stuffy. In the example shown in FIGS. 4A and 4B , the portion 31a of the outer glove 30 corresponding to the back portion 21a of the glove body 20 is covered solely with the porous first resin coating layer 41 made of foamed resin, thereby preventing the hands of the wearer from becoming stuffy.

[0051] The at least one resin coating layer 40, which is visible and exposed, can function as a non-slip layer when the wearer of the glove 10b performs manual work. Although not shown, when the at least one resin coating layer consists of only one resin coating layer, the resin coating layer can be considered the outermost layer, the entire outer surface of which is visible and exposed. To further enhance non-slip properties, the outermost layer of the at least one resin coating layer 40 is preferably a non-porous resin coating layer made of a non-foamed resin coating. In the example shown in FIGS. 4A and 4B , the outermost layer of the outer glove 30, covering the entire region 31b corresponding to the palm portion 21b of the glove body 20, and the entire palm-side region of the finger pocket 22 of the glove body 20, is the second resin coating layer 42 made of a non-foamed resin. This facilitates non-slip performance when the wearer of the glove 10b grasps an object. Furthermore, in the region where the non-porous second resin coating layer 42 made of a non-foamed resin is formed as the outermost layer, the porous first resin coating layer 41 is coated with the second resin coating layer 42. This is preferable in that the porous first resin coating layer 41, which is relatively easily damaged, is protected by the non-porous second resin coating layer 42, which is relatively less likely to be damaged, and in that the second resin coating layer 42 enhances the heat insulation, making it less likely for body heat to be lost from the hand of the wearer of the glove 10b to be exposed to a cold atmosphere.

[0052] The thickness of the resin coating layer constituting the externally visible exposed portion of the at least one resin coating layer 40 is not particularly limited as long as it does not contradict the object of the present invention. From the viewpoint of configuring the glove 10b to allow easy movement of the wearer's hand, when the resin coating layer constituting the exposed portion of the at least one resin coating layer 40 is made of a foamed resin, the thickness of the resin coating layer (for example, when the first resin coating layer 41 illustrated in FIG. 4A is made of a foamed resin, the thickness of the first resin coating layer 41 exposed on the back portion 31a) is preferably 2.0 mm or less, more preferably 1.5 mm or less. From a similar perspective, when one of the at least one resin coating layers 40 constituting the exposed portion is made of a non-foamed resin, the thickness of that resin coating layer (for example, when the second resin coating layer 42 illustrated in FIG. 4B is made of a non-foamed resin, the thickness of the second resin coating layer 42 exposed in the palm portion 31b) is preferably 1.0 mm or less, and more preferably 0.5 mm or less.

[0053] In a manufacturing method, when the at least one resin coating layer laminated on at least a part of the outer surface of the fabric of the outer glove consists of only one resin coating layer, the outer glove can be manufactured by knitting a glove base without any resin coating layer laminated thereon, placing the glove base on a hand mold, immersing at least a part of the glove base together with the hand mold in a resin solution, and drying the glove base after removing it from the resin solution, thereby forming one resin coating layer on the outer surface of the glove base. In addition, as a manufacturing method, when the at least one resin coating layer laminated on at least a part of the outer surface of the fabric of the outer glove is two resin coating layers, the outer glove can be manufactured by knitting a glove base without any resin coating layer laminated thereon, placing the glove base on a hand mold, immersing at least a part of the glove base together with the hand mold in a first resin solution, removing the glove base from the first resin solution and drying it to form a first resin coating layer, and then immersing the glove base together with the hand mold in a second resin solution so that at least a part of the first resin coating layer is immersed therein, removing the glove base from the second resin solution and drying it to form a second resin coating layer.

[0054] 4A and 4B show a glove 10b in which the outer glove 30 is joined to the glove body 20 so as to cover the entire side (outside) of the stitching 25a of the glove body 20. For example, the glove 10b can be produced by inserting the glove body 20 inside the outer glove 30 and joining a part of the outside (side of the stitching 25a) of the glove body 20 to a part of the inside of the outer glove 30. Therefore, in the external appearance of the glove 10b shown in FIGS. 4A and 4B, the stitching 25a of the glove body 20 is hidden by the outer glove 30 and cannot be seen. When producing a glove 10b including an outer glove 30 on which at least one resin coating layer 40 is laminated as described above, the glove body 30 is inserted inside the outer glove 30 on which at least one resin coating layer 40 is already laminated.

[0055] The joining portion between the glove body 20 and the outer glove 30 is not particularly limited as long as it does not contradict the object of the present invention. From the viewpoint of making it easy for a wearer of the glove 10b to move their fingers, it is preferable that the fingertip portions (finger pocket portion 22) of the glove body 20 and the portion of the outer glove 30 covering the fingertip portions of the glove body 20 are joined, and in this case, it is more preferable that a portion of each of the first to fifth finger pocket portions (22a to 22e) on the palm side of the glove body 20 is joined to the corresponding fingertip portions of the outer glove 30. Furthermore, from the viewpoint of making it easy for a wearer to insert their hand into the glove body 20 when wearing the glove 10b, it is preferable that the end of the hem portion 23 of the glove body 20 is joined to the corresponding portion of the outer glove 30. In order to prevent the glove body 20 from rolling up inside the outer glove 30 when the glove 10b is worn, it is preferable that a portion of the palm portion 21b (FIG. 1B) of the glove body 20 that is relatively close to the boundary with the hem portion 23 is joined to a portion of the outer glove 30 that corresponds to this portion.

[0056] The method for joining the glove body 20 and the outer glove 30 is not particularly limited as long as it does not contradict the object of the present invention, and may be any means that can be used to join the glove body (inner glove) and the outer glove in conventional double-layer gloves. For example, when joining the fingertip portions (finger pocket portions 22) of the glove body 20 to the corresponding portions of the outer glove 30, or when joining the palm portion 21a of the glove body 20 to the corresponding portions of the outer glove 30, they may be joined using a hot melt adhesive. For example, when joining the hem portion 23 of the glove body 20 to the corresponding portions of the outer glove 30, they may be joined by sewing using a serger or the like.

[0057] 4A and 4B illustrate a glove 10b shaped to be worn so as to cover the wearer's hand. Although not shown, in yet another embodiment, the shape of the outer glove 30 shown in FIGS. 4A and 4B may be modified to form a glove usable as a mitten, or a glove with arm cover shaped to be worn over at least a portion of the wearer's arm, including the hand. The portion of the outer glove on which at least one resin coating layer is formed is not limited to the portion illustrated in FIGS. 4A and 4B. As another example, not shown, the outer glove may be formed over the entire area of ​​the portion of the outer glove corresponding to the palm of the inner glove (the portion covering the palm), or the outer glove may be formed over the entire area of ​​the portion of the outer glove corresponding to the finger pocket of the inner glove (the portion covering the finger pocket).

[0058] The matters disclosed in this specification include the following. (1) A cut-resistant glove having a pile knit fabric, The pile knitted fabric is a knitted fabric in which a plurality of yarns including a cut-resistant ground yarn and a pile yarn are pile-knitted at a gauge of less than 10, The pile yarn forms a plurality of loops on the back of the pile knit fabric, the loops being pulled out longer than the ground yarn.

[0059] The present invention is not limited to the above-described embodiments and can be implemented in various forms with various improvements, modifications, or variations based on the knowledge of those skilled in the art without departing from the spirit of the present invention. The present invention may 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. For example, although right-hand gloves (10a, 10b) are illustrated in FIGS. 1A, 1B, 4A, and 4B, in still other embodiments, the gloves may be left-hand gloves, or a glove set including right-hand and left-hand gloves may also be used. For gloves used in applications where slightly inferior cut resistance compared to the gloves (10a, 10b) is acceptable, the glove body may be modified to have a pile knit fabric formed by knitting multiple yarns, including ground yarns and pile yarns, into a pile knit of 10 gauge or more. [Example]

[0060] The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

[0061] A double covering yarn A1 having the following composition was prepared. Double-covered yarn A1: A single stainless steel wire with a diameter of 35 μm (equivalent to a fineness of 74 dtex) was used as the core yarn (cut-resistant yarn), a para-aramid spun yarn with a fineness of 236 dtex spun from multiple para-aramid fibers was used as the first sheath yarn (reinforcing yarn), and a polyester spun yarn with a fineness of 295 dtex was used as the second sheath yarn (auxiliary yarn). The first sheath yarn was then wrapped around the core yarn at 1,000 turns / m in the Z direction to cover it, and then the second core yarn was wrapped around it at 1,000 turns / m in the S direction to cover it, resulting in double-covered yarn A1. The total fineness of this double-covered yarn A1 was equivalent to 605 dtex.

[0062] Further, two-ply yarn B1 and single yarn B2 having the following configurations were prepared. Two-ply yarn B1: An acrylic spun yarn with an acrylic count of 2 / 28 and a total fineness of 714 dtex was prepared as two-ply yarn B1, which was made by twisting together two single yarns. This two-ply yarn B1 was made by aligning an acrylic spun yarn with an acrylic count of 1 / 28 and a fineness of 357 dtex, with a twist number of 435 turns / m in the S direction, and an acrylic spun yarn with an acrylic count of 1 / 28 and a fineness of 357 dtex, with a twist number of 435 turns / m in the Z direction, and twisting them together at 235 turns / m in the Z direction to form a two-ply yarn with a total fineness of 714 dtex. Single yarn B2: An acrylic spun yarn having an acrylic count of 1 / 28 and a fineness equivalent to 357 dtex was prepared as single yarn B2. This single yarn B2 had a twist number of 325 turns / m in the Z direction.

[0063] Example 1 In Example 1, two double-covered yarns A1 were aligned to form a parallel yarn with a total fineness equivalent to 1210 dtex. This parallel yarn was used as the ground yarn. Furthermore, in Example 1, two-fold yarn B1 was used as the pile yarn. Based on this, a glove according to Example 1 was produced as a prototype. Just before the prototype, a two-fold yarn-like piece was obtained from this pile yarn (two-fold yarn B1) using the method described above, and the number of snarling crossings was measured. As shown in FIG. 3A , the number of snarling crossings was found to be two. Thereafter, in Example 1, seamless knitted gloves composed only of a pile knit fabric were produced as a prototype by performing pile knitting on a glove knitting machine SPG-R manufactured by Shima Seiki Mfg. Co., Ltd., with the ground yarn and pile yarn set at a 7-gauge setting. In the knitted gloves according to Example 1, the pile yarn formed loops that were pulled out longer than the ground yarn on the purl of the pile knit fabric. In addition, in the pile knit fabric from which the knitted gloves of Example 1 were knitted, the above-mentioned ratio (pile yarn fineness (dtex) / ground yarn fineness (dtex)) was 0.59.

[0064] When the glove of Example 1 was worn, it did not feel itchy and had a soft texture. Regarding the density of the terry knit fabric of the glove of Example 1, the number of stitches in the course direction was 9.2 per 1.0 inch (2.54 cm) and the number of stitches in the wale direction was 16.5 per 1.0 inch, as measured by the aforementioned measurement method. When a cross section of the glove of Example 1 cut in the thickness direction was observed under a microscope, the length of each loop included in the plurality of loops formed by the terry yarn was 9.0 mm on average, and the thickness of the thermal layer alone formed by the plurality of loops was 2.37 mm on average. A thermometer sensor was attached to the inner surface of the glove of Example 1, and the temperature of the inner surface of the glove was measured under the condition that 800 g of ice, a cylindrical shape with a diameter of 8 cm, was placed on the outer surface of the glove. The temperature was 23.7°C before the ice was placed and had dropped to 8.1°C three minutes after the ice was placed. The abrasion resistance of the glove according to Example 1 was evaluated as level E in the test described above in accordance with EN ISO 13997.

[0065] <Example 2> In Example 2, two double covering yarns A1 were aligned to form a drawn yarn with a total fineness equivalent to 1210 dtex, and this drawn yarn was used as the ground yarn. Also in Example 2, two single yarns B2 were aligned to form a drawn yarn with a total fineness equivalent to 714 dtex, and this drawn yarn was used as the pile yarn. Based on this, a glove according to Example 2 was produced as a prototype. Just before the prototype, a thread-like piece of this pile yarn (a drawn yarn formed by aligning two single yarns B2) was obtained by the method described above, and the number of snarling intersections was measured. As shown in FIG. 3B , the number of snarling intersections was 10. Thereafter, in Example 1, seamless knitted gloves composed only of a pile knit fabric were produced as a prototype by terry knitting the ground yarn and the pile yarn at a 7-gauge setting using the glove knitting machine SPG-R described above. In the knitted glove according to Example 2, the pile yarn formed loops that were pulled out longer than the ground yarn on the back stitch of the pile knit fabric.

[0066] When the glove of Example 2 was worn, a slightly itchy texture was felt. Regarding the density of the terry knit fabric of the glove of Example 2, the number of stitches in the course direction was 9.0 per 1.0 inch (2.54 cm) and the number of stitches in the wale direction was 16.5 per 1.0 inch, as measured by the aforementioned measurement method. When a cross section of the glove of Example 2 cut in the thickness direction was observed under a microscope, the length of each loop included in the multiple loops formed by the terry yarn was 8.00 mm on average, and the thickness of the thermal insulation layer alone formed by the multiple loops was 1.87 mm on average. A thermometer sensor was attached to the inner surface of the glove of Example 2, and the temperature of the inner surface of the glove was measured under the condition that 800 g of ice, a cylindrical shape with a diameter of 8 cm, was placed on the outer surface of the glove. The temperature was 23.6°C before the ice was placed and had dropped to 6.8°C three minutes after the ice was placed.

[0067] In Example 2, a pile knitted fabric was knitted under conditions similar to those of Example 1, but the pile yarn used in Example 2 was more likely to cause snare (more intersections of snare) than the pile yarn used in Example 1, resulting in shorter observed loop lengths and thinner thermal layers. These factors are thought to be the reason why Example 2 had slightly lower thermal insulation than Example 1. [Explanation of symbols]
