Definitions
- the present invention relates to a cut-resistant glove and, more particularly, to a cut-resistant glove to be used for protective products such as protective fabrics, protective clothes, protective aprons for cutting workers in edible meat processing works where sharp blades are used, and in glass producing or processing works or metal processing works where glass and metal plates with sharp edges are handled.
- a core-sheath composite yarn produced by winding a synthetic fiber and thus covering a core comprising a high strength yarn and a wire with the synthetic fiber is proposed, and concretely as an example, a glove obtained by knitting a core-sheath composite yarn produced by wrapping a nylon fiber in upper and lower double layers around a core comprising a 3,4′-diaminodiphenyl ether copolymer-polyparaphenylene terephthalamide fiber and a stainless wire is disclosed in Japanese Patent Application Laid-Open No. 1-239104.
- a composite spun yarn having a core-sheath structure produced by covering a core part of a single wire of a metal yarn, a filament yarn, or a spun yarn with a staple of an aromatic polyamide fiber is proposed in Japanese Patent Application Laid-Open No. 63-303138.
- a cut-resistant glove formed of a composite yarn comprising a fiber having a high strength and a high modulus of elasticity, and a metal thin wire in the surface and a bulky yarn or a natural fiber in the back face is proposed in Japanese Patent Application Laid-Open No. 2000-178812.
- a cut-resistant composite yarn comprising a glass fiber as a core part and a polyethylene fiber or aramid fiber as a sheath part, and further a covering fiber of a non-metallic and non-high performance fiber such as a polyester, nylon, or the like wrapped in mutually opposite directions is proposed in U.S. Pat. No. 6,467,251.
- a cut-resistant composite yarn comprising a core part composed of a strand of wire and an extended chain polyethylene fiber being positioned parallel to each other, wrapped around the core with double layer-covering strands in mutually opposite directions, in which an aramid fiber is not used, is disclosed in U.S. Pat. No. 5,644,907.
- the above-mentioned conventional composite yarns are inferior in moisture absorption property and also inferior in knitting processability, for example, since the stainless wire and the glass fiber are sometimes ruptured in the case of producing gloves by knitting the composite yarns and gloves produced by knitting the composite yarns give uncomfortable putting-on-feeling or use feeling, and particularly, the ruptured stainless wire and glass fiber irritatingly stimulate the skin, and therefore, the workability in the case where the gloves are put on is not satisfactory. Especially, there is a serious problem that the stainless wire and glass fiber used as cores are exposed to the outside of the composite yarns and prickly irritate hands and fingers.
- the present invention provides a cut-resistant glove which is excellent not only in elastic property and moisture absorption property, but also in putting-on-feeling or use feeling and workability at the time the glove is put on, which is made from a composite yarn having an excellent knitting processability as well as a good moisture adsorption property.
- Inventors of the present invention have made an intensive series of investigations for solving the above-mentioned problems and have found that a cut-resistant glove which is formed of a composite yarn comprising a core and a covering layer formed by wrapping a covering fiber around the core, the core being composed of a metal thin wire and an attending yarn comprising a filament yarn, the surface of which is coated with a rubber or a resin could attain the above-mentioned objects.
- the inventors of the present invention have found that in the case of knitting a glove, plating is carried out by using a specified fiber and the plated fiber is knitted to be set in the inner side of the glove, so that the glove could further be improved in elastic property, moisture absorption property, the putting-on-feeling or use feeling and workability at the time the glove is put on.
- the present invention has been accomplished based on the above-mentioned findings.
- the present invention for attaining the above-mentioned object encompasses, in claim 1 , a cut-resistant glove which is formed of a composite yarn comprising a core and a covering layer formed by wrapping a covering fiber around the core, the core being composed of a metal thin wire and an attending yarn comprising a filament yarn, the surface of which is coated with a rubber or a resin.

- the composite yarn used in a cut-resistant glove of the present invention comprises, as shown by FIG. 1 , a core 1 and a covering layer 3 formed by wrapping a covering fiber 2 around the core 1 .
- the above-mentioned core 1 comprises a metal thin wire 1 a and an attending yarn 1 b , which is a filament yarn.
- the metal thin wire 1 a used in the present invention is preferably a stainless, titanium, aluminum, silver, nickel, copper, bronze or the like with a high strength and a high modulus of elasticity, and particularly, a stainless is preferable since it is economical and has a high strength as well as it is excellent in chemical stability and corrosion resistance.
- “stainless” is correctly “stainless steel”, however, domestically it is generally abbreviated as “stainless” or “stain” and therefore, in this specification, the term “stainless” is used for its abbreviation.
- a non-processed wire is used in the present invention since a twisted wire is hard and deteriorates feeling of a product formed of a composite yarn, for example, a glove (hereinafter, a glove is taken as a representative product formed of a composite yarn.).
- the metal thin wire 1 a in the present invention has a thickness of preferably 10 to 70 ⁇ m, more preferably 15 to 35 ⁇ m in terms of the knitting processability of the composite yarn and workability in the state of putting on a glove.
- SUS 304 is preferable in terms of softness and bending strength.
- the metal thin wire 1 a 1 to 4 pieces are preferred to use. In the case of more than 4 pieces, a glove becomes hard to deteriorate workability in the state of putting on the glove, and therefore that is not preferable.
- the metal thin wire 1 a of the core is ruptured when it is wrapped with the covering fiber 2 as it is in a covering step and therefore, the attending yarn 1 b is needed for the metal thin wire 1 a .
- the attending yarn 1 b a non-processed filament yarn is used since a processed yarn such as a twist yarn has rather considerable elastic property. If a yarn having the elastic property is used as the attending yarn 1 b , the yarn to be used for covering in the successive covering step is also provided with the elastic property. Meanwhile, the metal thin wire 1 a itself scarcely has the elastic property and if the composite yarn is expanded after the covering with the covering fiber 2 is formed, the metal thin wire 1 a cannot stand in the elongation and thus ruptured.
- the ruptured metal thin wire 1 a springs out of the covering layer 3 of the composite yarn 2 and, for example, when the composite yarn is knitted into a glove product, the metal thin wire 1 a prickly stings the skin of a hand of the user of the glove and thus worsens the putting-on-feeling and use feeling.
- the attending yarn 1 b contrarily has the contractive property, the same phenomenon occurs.
- the metal thin wire 1 a in the case where the attending yarn 1 b contracts, the metal thin wire 1 a cannot contract and therefore is sagged and since the sagging cannot be released, the metal thin wire 1 a springs out of the covering layer 3 of the composite yarn 2 and irritates the skin of a hand of the user of the glove and gives unpleasant feeling.
- the attending yarn 1 b used in the present invention is preferably a filament fiber scarcely having not only the dynamic elasticity, but also the elasticity affected by heat and chemicals.
- filament fiber are polyethylene, ultra high molecular weight polyethylene, which are reinforced polyethylene (e.g. trade name: Dyneema, manufactured by Toyobo Co., Ltd.), polyester, polyparaphenylene terephthalamide (e.g. trade name: Kevlar, manufactured by Du Pont de Nemours & Co.), liquid crystal polymer, high strength polyarylate (e.g. trade name: Vectran, manufactured by Kuraray Co., Ltd.), and the like.
- ultra high molecular polyethylene, polyparaphenylene terephthalamide and polyester are preferable since those are very stable physically and chemically. These may be used singly or, if necessary, in combination of two or more.
- the fineness of these attending yarns 1 b is, in general, preferably 50 to 600 denier, more preferably 100 to 450 denier. If it is thinner than 50 denier, the rupture prevention effect of the metal thin wire 1 a tends to be weakened. In the case where an attending yarn with a thickness exceeding 600 denier is used, the composite yarn obtained becomes thick and tends to give stiff feeling, which deteriorates the putting-on-feeling and use feeling.
- the number of the filaments forming the attending yarn 1 b is preferable to be higher since the attending yarn 1 b winds the metal thin wire to prevent exposure of the surface of the metal thin wire 1 a and it is, in general, preferably not less than 100 filaments, more preferably 100 to 1000 filaments, and still more preferably 200 to 1000 filaments. If it is less than 100 filaments, the effect of winding the metal thin wire 1 a becomes insufficient, the knitting processability is decreased and the putting-on-feeling and use feeling tend to be worsened. On the other hand, if it is more than 1000 filaments, the cost of the attending yarn tends to increase, which makes it difficult to use.
- the attending yarn 1 b is wound around the metal thin wire 1 a at 2 to 60 turns, preferably 2 to 60 turns, more preferably 15 to 50 turns, still more preferably 25 to 45 turns per meter of the metal thin wire.
- This winding prevents the metal thin wire not only from cutting when tension was imposed, but also from exposing its surface when flexure or distortion took place. In the case of less than 2 turns, the above-mentioned effects are not provided satisfactorily, when knitted into a glove, the metal thin wire 1 a ruptures, springs out and irritates the skin of a hand to thus deteriorate touch feeling, putting-on-feeling and use feeling.
- the attending yarn 1 b 1 to 3 pieces are preferred. In the case of more than 3 pieces, the attending yarn tends to become thick, which not only deteriorates knitting processability, but also tends to worsen putting-on-feeling to stiff feeling.
- the covering layer 3 is formed by wrapping the covering fiber 2 around the core 1 composed of the metal thin wire 1 a and the attending yarn 1 b.
- the covering fiber 2 is not particularly limited and determined in consideration of the knitting processability, resin coating processability, the putting-on-feeling, use feeling such as touch feeling and fitting of products, the moisture absorption property, and the like. From a viewpoint of these properties, as the covering fiber 2 , polyethylene, polyaramide, polyester, polyamide (nylon), polyacryl, cotton, wool and the like are preferable.
- the covering fiber 2 may be multifilaments, twist yarn or spun yarn. Among these, polyester, polyamide (nylon), cotton and wool are more preferable. As the spun yarn, cotton or polyester is preferable in terms of softness.
- As the filament of the covering fiber 2 it is preferable to be crimped, particularly, crimped polyester or polyamide is preferable in terms of good touch feeling.
- the fineness of the covering fiber 2 is, in general, preferably 50 to 500 denier (100 to 10 yarn counts) and more preferably 50 to 300 denier (100 to 15 yarn counts) in terms of the prevention of the surface exposure of the metal thin wire 1 a and the putting-on-feeling and use feeling of knitted products.
- the number of the filaments is preferably 20 to 500 filaments. In the case of less than 20 filaments, the thickness of the filament becomes large to thus result in stiff feeling, on the other hand, in the case of more than 500 filaments, the cost becomes high and thus that is not preferable.
- the covering fiber 2 is wrapped around the core 1 .
- the number of the layers of wrapping the coating fiber 2 if the number of the layers is small, the effect of covering the core 1 becomes so insufficient as to expose the core to the outside of the covering layer 3 in some cases, and on the other hand, if the number is large, the knitting processability of the composite yarn tends to be deteriorated and it results in stiff feeling and deteriorates the putting-on-feeling and use feeling.
- it is preferably to be two or three layers, more preferably, two layers, in particular.
- the covering fiber 2 itself is wrapped in opposite directions. That is, the covering fiber 2 a in the first layer is wrapped clockwise and the covering fiber 2 b in the second layer is wrapped counterclockwise to form the first covering layer 3 a and the second covering layer 3 b , respectively.
- the number of the wrapping turns of the covering fiber 2 is preferably 300 to 1200 turns, more preferably 450 to 1000 turns, per one meter of the length of the core 1 .
- the purpose of preventing the surface exposure of the metal thin wire 1 a is not attained adequately, on the other hand, in the case of more than 1200 turns, the obtained composite yarn becomes hard, which is not preferable.
- the covering fiber 2 1 to 6 pieces per one layer are suitable. In the case of more than 6 pieces, a step for producing a composite yarn tends to become complicated and the obtained composite yarn tends to give stiff feeling.
- the composite yarn obtained in the above manner is knitted into a cut-resistant glove.
- plating is carried out using a fiber having good touch feeling and excellent moisture absorption property and knitting is carried out to set the plated fiber in the inner side of the glove, so that the cut-resistant glove excellent in the putting-on-feeling or use feeling such as touch feeling and in the moisture absorption property can be produced.
- synthetic fibers such as composite fibers of a polyurethane fiber and at least one synthetic fiber selected from polyamide, polyethylene, polyester, polyphenylene terephthalamide and rayon, synthetic fibers such as polyamide, polyethylene, polyester, polyphenylene terephthalamide, rayon and the like, and natural fibers such as cotton are preferable.
- the fiber for the plating may properly be determined depending on the use and a plurality of kinds of fibers may be used.
- the thickness of the plating fiber is preferably 50 to 700 denier, more preferably 50 to 550 denier, for one fiber in terms of the putting-on-feeling and the workability. If it is thinner than 50 denier, the effect of plating tends to be insufficient. If it exceeds 700 denier, the knitted density of the plating fiber becomes high and the knitting workability tends to be deteriorated.
- the number of the fibers to be used for plating may properly be determined and it is preferably 1 to 7 fibers, more preferably 1 to 5 fibers in terms of the easy plating processability.
- the cut-resistant glove obtained in the above manner is coated with a rubber or a resin for imparting non-slip property, waterproofness and strength.
- a rubber or a resin for imparting non-slip property, waterproofness and strength As the rubber and the resin used for coating, those having been used heretofore may be suitably used, for example, as the rubber, any of natural rubber, synthetic rubber and modified bodies thereof may be used, and as the synthetic rubber, nitrile butadiene rubber (NBR), styrene butadiene rubber (SBR), chloroprene rubber (CR), silicone rubber, fluorinated rubber, chlorosulfonated polyethylene rubber, isoprene rubber and modified bodies thereof, and the like are exemplified.

- the whole of the glove may be coated, and for the prevention of sweating, a part excepting the back of the glove may be coated.
- a part of finger tops may be coated.
- the coating layer may be a singly layer or a plural layer and if the coating layer comprises, for example, two layers, the first layer and the second layer may be different materials.

Abstract
A cut-resistant glove is provided which is formed of a composite yarn comprising a core and a covering layer formed by wrapping a covering fiber around the core, the core being composed of a metal thin wire and an attending yarn comprising a filament yarn, the surface of which is coated with a rubber or a resin. The cut-resistant glove is excellent not only in moisture absorption property, putting-on-feeling, use feeling and workability in the state of being put on, but also in non-slip property, water proofness, strength and cut-resistant property.
Description
- The present invention relates to a cut-resistant glove and, more particularly, to a cut-resistant glove to be used for protective products such as protective fabrics, protective clothes, protective aprons for cutting workers in edible meat processing works where sharp blades are used, and in glass producing or processing works or metal processing works where glass and metal plates with sharp edges are handled.
- As such yarns used for a cut-resistant glove, use of metal yarn (wire) alone for armors or the like has formerly been a main stream especially in Europe. In recent years, to make such yarn lightweight and to improve the workability and strength, various kinds of composite yarns comprising metal yarn in combination with cotton yarn and high strength filaments have been proposed.
- For example, a core-sheath composite yarn produced by winding a synthetic fiber and thus covering a core comprising a high strength yarn and a wire with the synthetic fiber is proposed, and concretely as an example, a glove obtained by knitting a core-sheath composite yarn produced by wrapping a nylon fiber in upper and lower double layers around a core comprising a 3,4′-diaminodiphenyl ether copolymer-polyparaphenylene terephthalamide fiber and a stainless wire is disclosed in Japanese Patent Application Laid-Open No. 1-239104.
- Also, a composite spun yarn having a core-sheath structure produced by covering a core part of a single wire of a metal yarn, a filament yarn, or a spun yarn with a staple of an aromatic polyamide fiber is proposed in Japanese Patent Application Laid-Open No. 63-303138.
- Also, a cut-resistant glove formed of a composite yarn comprising a fiber having a high strength and a high modulus of elasticity, and a metal thin wire in the surface and a bulky yarn or a natural fiber in the back face is proposed in Japanese Patent Application Laid-Open No. 2000-178812.
- Further, a cut-resistant composite yarn comprising a glass fiber as a core part and a polyethylene fiber or aramid fiber as a sheath part, and further a covering fiber of a non-metallic and non-high performance fiber such as a polyester, nylon, or the like wrapped in mutually opposite directions is proposed in U.S. Pat. No. 6,467,251.
- Further, a cut-resistant fiber produced by wrapping a polyester fibers in opposite directions around a core part composed of a stainless steel wire and an anti-microbial treated acetate type fiber and an apparel such as a glove produced from the fiber are proposed in U.S. Pat. No. 6,266,951.
- Furthermore, a cut-resistant composite yarn comprising a core part composed of a strand of wire and an extended chain polyethylene fiber being positioned parallel to each other, wrapped around the core with double layer-covering strands in mutually opposite directions, in which an aramid fiber is not used, is disclosed in U.S. Pat. No. 5,644,907.
- However, although having cut resistance, the above-mentioned conventional composite yarns are inferior in moisture absorption property and also inferior in knitting processability, for example, since the stainless wire and the glass fiber are sometimes ruptured in the case of producing gloves by knitting the composite yarns and gloves produced by knitting the composite yarns give uncomfortable putting-on-feeling or use feeling, and particularly, the ruptured stainless wire and glass fiber irritatingly stimulate the skin, and therefore, the workability in the case where the gloves are put on is not satisfactory. Especially, there is a serious problem that the stainless wire and glass fiber used as cores are exposed to the outside of the composite yarns and prickly irritate hands and fingers.
- Further, when sharp blades and the like are handled, there are included problems that cut dust of a covering fiber arises, and that water, oil and the like soak into a glove at the time of working due to the absence of waterproofness.
- In light of the foregoing situation, the present invention provides a cut-resistant glove which is excellent not only in elastic property and moisture absorption property, but also in putting-on-feeling or use feeling and workability at the time the glove is put on, which is made from a composite yarn having an excellent knitting processability as well as a good moisture adsorption property.
- Inventors of the present invention have made an intensive series of investigations for solving the above-mentioned problems and have found that a cut-resistant glove which is formed of a composite yarn comprising a core and a covering layer formed by wrapping a covering fiber around the core, the core being composed of a metal thin wire and an attending yarn comprising a filament yarn, the surface of which is coated with a rubber or a resin could attain the above-mentioned objects.
- Further, the inventors of the present invention have found that in the case of knitting a glove, plating is carried out by using a specified fiber and the plated fiber is knitted to be set in the inner side of the glove, so that the glove could further be improved in elastic property, moisture absorption property, the putting-on-feeling or use feeling and workability at the time the glove is put on.

core 1 comprises a metal thin wire 1 a and an attending yarn 1 b, which is a filament yarn. - The metal thin wire 1 a used in the present invention is preferably a stainless, titanium, aluminum, silver, nickel, copper, bronze or the like with a high strength and a high modulus of elasticity, and particularly, a stainless is preferable since it is economical and has a high strength as well as it is excellent in chemical stability and corrosion resistance. Meanwhile, “stainless” is correctly “stainless steel”, however, domestically it is generally abbreviated as “stainless” or “stain” and therefore, in this specification, the term “stainless” is used for its abbreviation.
- As the metal thin wire 1 a, a non-processed wire is used in the present invention since a twisted wire is hard and deteriorates feeling of a product formed of a composite yarn, for example, a glove (hereinafter, a glove is taken as a representative product formed of a composite yarn.).
- For example, as a thin wire of a stainless, those with 40 to 50 μm thickness are commonly used for such purposes. The metal thin wire 1 a in the present invention has a thickness of preferably 10 to 70 μm, more preferably 15 to 35 μm in terms of the knitting processability of the composite yarn and workability in the state of putting on a glove. As a practical material for the stainless, SUS 304 is preferable in terms of softness and bending strength. As the metal
thin wire 1 a, 1 to 4 pieces are preferred to use. In the case of more than 4 pieces, a glove becomes hard to deteriorate workability in the state of putting on the glove, and therefore that is not preferable. - The metal thin wire 1 a of the core is ruptured when it is wrapped with the covering
fiber 2 as it is in a covering step and therefore, the attending yarn 1 b is needed for the metal thin wire 1 a. As the attending yarn 1 b, a non-processed filament yarn is used since a processed yarn such as a twist yarn has rather considerable elastic property. If a yarn having the elastic property is used as the attending yarn 1 b, the yarn to be used for covering in the successive covering step is also provided with the elastic property. Meanwhile, the metal thin wire 1 a itself scarcely has the elastic property and if the composite yarn is expanded after the covering with the coveringfiber 2 is formed, the metal thin wire 1 a cannot stand in the elongation and thus ruptured. The ruptured metal thin wire 1 a springs out of thecovering layer 3 of thecomposite yarn 2 and, for example, when the composite yarn is knitted into a glove product, the metal thin wire 1 a prickly stings the skin of a hand of the user of the glove and thus worsens the putting-on-feeling and use feeling. On the other hand, ever if the attending yarn 1 b contrarily has the contractive property, the same phenomenon occurs. That is, in the case where the attending yarn 1 b contracts, the metal thin wire 1 a cannot contract and therefore is sagged and since the sagging cannot be released, the metal thin wire 1 a springs out of thecovering layer 3 of thecomposite yarn 2 and irritates the skin of a hand of the user of the glove and gives unpleasant feeling. - Accordingly, the attending yarn 1 b used in the present invention is preferably a filament fiber scarcely having not only the dynamic elasticity, but also the elasticity affected by heat and chemicals. Practically, examples of such filament fiber are polyethylene, ultra high molecular weight polyethylene, which are reinforced polyethylene (e.g. trade name: Dyneema, manufactured by Toyobo Co., Ltd.), polyester, polyparaphenylene terephthalamide (e.g. trade name: Kevlar, manufactured by Du Pont de Nemours & Co.), liquid crystal polymer, high strength polyarylate (e.g. trade name: Vectran, manufactured by Kuraray Co., Ltd.), and the like. Among these, ultra high molecular polyethylene, polyparaphenylene terephthalamide and polyester are preferable since those are very stable physically and chemically. These may be used singly or, if necessary, in combination of two or more.
- The fineness of these attending yarns 1 b is, in general, preferably 50 to 600 denier, more preferably 100 to 450 denier. If it is thinner than 50 denier, the rupture prevention effect of the metal thin wire 1 a tends to be weakened. In the case where an attending yarn with a thickness exceeding 600 denier is used, the composite yarn obtained becomes thick and tends to give stiff feeling, which deteriorates the putting-on-feeling and use feeling. The number of the filaments forming the attending yarn 1 b is preferable to be higher since the attending yarn 1 b winds the metal thin wire to prevent exposure of the surface of the metal thin wire 1 a and it is, in general, preferably not less than 100 filaments, more preferably 100 to 1000 filaments, and still more preferably 200 to 1000 filaments. If it is less than 100 filaments, the effect of winding the metal thin wire 1 a becomes insufficient, the knitting processability is decreased and the putting-on-feeling and use feeling tend to be worsened. On the other hand, if it is more than 1000 filaments, the cost of the attending yarn tends to increase, which makes it difficult to use.
- The attending yarn 1 b is wound around the metal thin wire 1 a at 2 to 60 turns, preferably 2 to 60 turns, more preferably 15 to 50 turns, still more preferably 25 to 45 turns per meter of the metal thin wire. This winding prevents the metal thin wire not only from cutting when tension was imposed, but also from exposing its surface when flexure or distortion took place. In the case of less than 2 turns, the above-mentioned effects are not provided satisfactorily, when knitted into a glove, the metal thin wire 1 a ruptures, springs out and irritates the skin of a hand to thus deteriorate touch feeling, putting-on-feeling and use feeling. On the other hand, in the case of more than 60 turns, when tension is imposed, the wound attending yarn is easy to elongate as compared with the metal thin wire being positioned straight and thus tension cannot be dispersed to the attending yarn so that the metal thin wire tends to be ruptured.
- As the attending
yarn 1 b, 1 to 3 pieces are preferred. In the case of more than 3 pieces, the attending yarn tends to become thick, which not only deteriorates knitting processability, but also tends to worsen putting-on-feeling to stiff feeling. - As described above, the
covering layer 3 is formed by wrapping the coveringfiber 2 around thecore 1 composed of the metal thin wire 1 a and the attending yarn 1 b. - The covering
fiber 2 is not particularly limited and determined in consideration of the knitting processability, resin coating processability, the putting-on-feeling, use feeling such as touch feeling and fitting of products, the moisture absorption property, and the like. From a viewpoint of these properties, as the coveringfiber 2, polyethylene, polyaramide, polyester, polyamide (nylon), polyacryl, cotton, wool and the like are preferable. The coveringfiber 2 may be multifilaments, twist yarn or spun yarn. Among these, polyester, polyamide (nylon), cotton and wool are more preferable. As the spun yarn, cotton or polyester is preferable in terms of softness. As the filament of the coveringfiber 2, it is preferable to be crimped, particularly, crimped polyester or polyamide is preferable in terms of good touch feeling. - The fineness of the covering
fiber 2 is, in general, preferably 50 to 500 denier (100 to 10 yarn counts) and more preferably 50 to 300 denier (100 to 15 yarn counts) in terms of the prevention of the surface exposure of the metal thin wire 1 a and the putting-on-feeling and use feeling of knitted products. In the case of the covering fiber comprising filaments, the number of the filaments is preferably 20 to 500 filaments. In the case of less than 20 filaments, the thickness of the filament becomes large to thus result in stiff feeling, on the other hand, in the case of more than 500 filaments, the cost becomes high and thus that is not preferable. - The covering
fiber 2 is wrapped around thecore 1. With respect to the number of the layers of wrapping thecoating fiber 2, if the number of the layers is small, the effect of covering thecore 1 becomes so insufficient as to expose the core to the outside of thecovering layer 3 in some cases, and on the other hand, if the number is large, the knitting processability of the composite yarn tends to be deteriorated and it results in stiff feeling and deteriorates the putting-on-feeling and use feeling. Accordingly, it is preferably to be two or three layers, more preferably, two layers, in particular. In the case where the coveringfiber 2 is wrapped in two layers, as shown inFIG. 1 , the coveringfiber 2 itself is wrapped in opposite directions. That is, the coveringfiber 2 a in the first layer is wrapped clockwise and the coveringfiber 2 b in the second layer is wrapped counterclockwise to form thefirst covering layer 3 a and thesecond covering layer 3 b, respectively. - The number of the wrapping turns of the covering
fiber 2 is preferably 300 to 1200 turns, more preferably 450 to 1000 turns, per one meter of the length of thecore 1. In the case of less than 300 turns, the purpose of preventing the surface exposure of the metal thin wire 1 a is not attained adequately, on the other hand, in the case of more than 1200 turns, the obtained composite yarn becomes hard, which is not preferable. - As the covering
fiber - The composite yarn obtained in the above manner is knitted into a cut-resistant glove. At the time of producing the cut-resistant glove by knitting the composite yarn of the present invention, plating is carried out using a fiber having good touch feeling and excellent moisture absorption property and knitting is carried out to set the plated fiber in the inner side of the glove, so that the cut-resistant glove excellent in the putting-on-feeling or use feeling such as touch feeling and in the moisture absorption property can be produced.
- As such a plating fiber, synthetic fibers such as composite fibers of a polyurethane fiber and at least one synthetic fiber selected from polyamide, polyethylene, polyester, polyphenylene terephthalamide and rayon, synthetic fibers such as polyamide, polyethylene, polyester, polyphenylene terephthalamide, rayon and the like, and natural fibers such as cotton are preferable.
- The fiber for the plating may properly be determined depending on the use and a plurality of kinds of fibers may be used. The thickness of the plating fiber is preferably 50 to 700 denier, more preferably 50 to 550 denier, for one fiber in terms of the putting-on-feeling and the workability. If it is thinner than 50 denier, the effect of plating tends to be insufficient. If it exceeds 700 denier, the knitted density of the plating fiber becomes high and the knitting workability tends to be deteriorated. The number of the fibers to be used for plating may properly be determined and it is preferably 1 to 7 fibers, more preferably 1 to 5 fibers in terms of the easy plating processability.
- The cut-resistant glove obtained in the above manner is coated with a rubber or a resin for imparting non-slip property, waterproofness and strength. As the rubber and the resin used for coating, those having been used heretofore may be suitably used, for example, as the rubber, any of natural rubber, synthetic rubber and modified bodies thereof may be used, and as the synthetic rubber, nitrile butadiene rubber (NBR), styrene butadiene rubber (SBR), chloroprene rubber (CR), silicone rubber, fluorinated rubber, chlorosulfonated polyethylene rubber, isoprene rubber and modified bodies thereof, and the like are exemplified. As the resin, polyvinyl chloride, polyurethane, ethylene-vinyl alcohol copolymer, polyvinyl acetate and modified bodies thereof, and the like are exemplified. These may be used singly or, if necessary, in combination of two or more.
- The coating area of the glove with these rubbers or the resins is not specifically limited and may be properly determined depending on uses of the glove. For example, in the case of a glove for water-related work, the whole of the glove may be coated, and for the prevention of sweating, a part excepting the back of the glove may be coated. Moreover, in the case of a glove for fine work, only a part of finger tops may be coated. The coating layer may be a singly layer or a plural layer and if the coating layer comprises, for example, two layers, the first layer and the second layer may be different materials.

Moreover, since the cut-resistant glove is coated on its surface with a rubber or resin, it is excellent not only in non-slip property, water proofness and strength, but also in cut-resistant property.
- Further, sharp blades and the like are handled with the cut-resistant glove of the present invention being put on, since it is coated with a rubber or resin, troubles such as cutting of a covering fiber are difficult to occur, and even when the covering fiber is cut off, cut dust is captured by the rubber or resin to thus prevent the generation of such dust.
- Moreover, in the case of knitting a glove with the above-mentioned composite yarn, if a fiber is plated and the plated fiber is knitted to set it in the inside of the glove, the cut-resistant glove can be provided which is further improved not only in the elastic property and the moisture absorption property, but also in the putting-on-feeling or use feeling and workability at the time the glove is put on.
- As stated above, the cut-resistant glove of the present invention is excellent not only in putting-on-feeling, use feeling and workability at the time the glove is put on, but also in non-slip property, water proofness, strength and cut-resistant property.
