Cut resistant glove

0001The present invention relates to composite fibers, and more specifically, for example, in a meat processing work using a sharp blade, a glass manufacturing or processing work for handling a glass with a sharp edge or a metal plate, a metal processing work, or the like. Concerning composite fibers used in safety protective products such as safety protective cloths, protective clothing, protective aprons, and protective gloves used for protection.

0002In the past, it was the mainstream to use only metal fibers such as armor as this kind of fiber, especially in the West. In recent years, various composite fibers of metal fibers and cotton threads or high-strength filaments have been proposed for the purpose of reducing weight, improving workability, strength, and the like. For example, a core-sheath composite yarn in which a synthetic fiber is wound around a core material composed of a high-strength fiber and a wire and coated is proposed. Specifically, as an example, a 3,4'-diaminodiphenyl ether copolymerized polyparaphenylene terephthalamide fiber is proposed. Disclosed are gloves knitted with a core-sheath composite yarn in which nylon fibers are double-wound up and down with a core material of a stainless wire and a stainless wire (see Patent Document 1). Further, a composite spun yarn having a core-sheath structure in which a core made of a single wire of a metal fiber, a filament yarn or a spun yarn is coated with a staple of an aromatic polyamide fiber has been proposed (see Patent Document 2). Further, a cut-resistant glove in which a composite yarn composed of high-strength and high elastic modulus fibers and fine metal wires is arranged on the front surface and bulky processed yarn or natural fiber is arranged on the back surface has been proposed (see Patent Document 3). Further, a cut-resistant composite fiber in which glass fiber is used as a core, polyethylene fiber or aramid fiber is used as a sheath, and coated fibers made of non-metal and non-high performance fibers such as polyester and nylon are wound in opposite directions. It has been proposed (see Patent Document 4). Further, there have been proposed cut-resistant fibers in which polyester fibers are wound in opposite directions around a core made of stainless steel wire and acetate-based fibers treated with antibacterial properties, and apparel such as gloves made of the fibers (Patent Document 5). reference). In addition, it does not use aramid fibers coated with a core consisting of wire strands and stretched polyethylene fiber strands placed parallel to each other and at least two layers of strands wound around the core in opposite directions. Cut-resistant composite fibers are disclosed (see Patent Document 6). However, although the conventional composite fiber as described above has cut resistance, it has poor hygroscopicity, and the stainless wire or glass fiber may be cut when knitting gloves or the like using the composite fiber. Knitting workability is poor, and for example, gloves knitted with the composite fiber are uncomfortable to wear and feel uncomfortable. In particular, cut stainless wire and glass fiber irritate the skin and workability when wearing gloves is also good. Not satisfying. In particular, there is a problem that the stainless steel wire or glass fiber used as the core material is exposed to the outside of the composite fiber, and the tingling sensation that irritates the fingers is large. In view of such circumstances, it is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a composite fiber having good hygroscopicity and excellent knitting processability.

0007<figref num="1">FIG. 1 is a schematic view showing an example of the composite fiber of the present invention.</figref>

0008As shown in FIG. 1, the present invention comprises a core material 1 and a coating layer 3 in which a coating fiber 2 is wound around the core material 1. The core material 1 is composed of a thin metal wire 1a and a thread 1b made of a filament thread. The thin metal wire 1a used in the present invention is preferably stainless steel, titanium, aluminum, silver, nickel, copper, bronze, etc. with high strength and high elastic modulus, and is particularly low cost, high strength, and chemically stable. Stainless steel is preferable because it does not easily rust. Although stainless steel is correctly stainless steel, it is also abbreviated as stainless steel in the present invention because it is generally abbreviated as stainless steel or stainless steel in Japan. It should be noted that the thin metal wire 1a is hard when twisted, and the texture of a product using a composite fiber, for example, a glove (hereinafter, a glove is taken up as a typical example of a product using a composite fiber) is deteriorated. Use unprocessed wire. For example, thin stainless steel wires are usually used in such applications with a thickness of 40 to 50 μm. The fine metal wire 1a in the present invention is preferably 10 to 70 μm, more preferably 15 to 35 μm, in terms of knitting workability of the composite fiber and workability when using gloves. As the material of stainless steel, SUS304 is preferable because it is soft and resistant to bending. It is preferable that 1 to 4 fine metal wires 1a are used. If the number of gloves exceeds four, the gloves become hard and workability when wearing gloves deteriorates, which is not preferable.

0009If the thin metal wire 1a of the core material is to be coated with the coating fiber 2 as it is, the thin metal wire 1a is cut in the coating process, so that the thread 1b is required. As the splicing yarn 1b, a processed yarn such as a twisted yarn has not a little elasticity, so an unprocessed filament yarn is used. If a stretchable thread is used as the thread 1b, the thread to be coated in the subsequent coating process also has elasticity. By the way, since the thin metal wire 1a itself has almost no elasticity, when the composite fiber is stretched after being coated with the coating fiber 2, the thin metal wire 1a cannot withstand the stretching and the thin metal wire 1a is cut. The cut metal wire 1a jumps out from the coating layer 3 of the composite fiber 2, and when it is used as a glove product, for example, it irritates the skin of the glove user's hand with a tingling sensation, and the wearing comfort and usability deteriorate. It will be. Contrary to the above, the same applies when the thread 1b is contractile. That is, when the thread 1b contracts, the thin metal wire 1a does not contract, so that bending occurs. However, since this bending has no escape, it jumps out from the coating layer 3 of the composite fiber 2 and is handed by the glove user. It will irritate and cause discomfort to the skin.

0010Therefore, the boring yarn 1b used in the present invention is preferably a filament yarn having less expansion and contraction due to the influence of heat and chemicals as well as mechanical expansion and contraction. Specifically, polyethylene, ultra-high molecular weight polyethylene which is reinforced polyethylene (for example, trade name: Dyneema, manufactured by Toyo Spinning Co., Ltd.), polyester, polyparaphenylene terephthalamide (for example, trade name: Kevlar, manufactured by DuPont), etc. Filament yarn can be mentioned. Among these, ultra-high molecular weight polyethylene, polyparaphenylene terephthalamide, and polyester are preferable because they have extremely high physical stability and high chemical stability. These may be used alone or in combination of two or more as required. The thickness of the thread 1b may be appropriately selected depending on the use of the composite fiber and the like, but is usually preferably 50 to 600 denier, more preferably 100 to 450 denier. Those with less than 50 denier tend to have a weaker cutting prevention effect on the thin metal wire 1a. Further, when a yarn exceeding 600 denier is used, the obtained composite fiber becomes thick, a stiff feeling is generated, and the wearing comfort and the usability tend to be deteriorated. Further, it is preferable that the number of filaments constituting the thread 1b is large because it wraps the thin metal wire and it is difficult to expose the fine metal wire 1a to the surface. Usually, 100 filaments or more are preferable, and 100 to 1000 filaments are more preferable. More preferably, it is 200 to 1000 filaments. If it is less than 100 filaments, the effect of wrapping the thin metal wire 1a is insufficient, the knitting workability is lowered, and the wearing comfort and usability tend to be lowered. It tends to be difficult to use.

0011Further, the thread 1b needs to be wound around the thin metal wire 1a 5 to 60 times, preferably 15 to 50 times, more preferably 25 to 45 times per 1 m of the thin metal wire. By this winding, it is possible to prevent the thin metal wire from being cut when tension is applied to the composite yarn, and it is possible to prevent the surface of the thin metal wire from being exposed when bending or strain occurs. If the wrapping is less than 5 times, the above effect will not be fully exhibited. For example, when a glove is used, the thin metal wire 1a will be cut and pop out, resulting in a tingling sensation and poor tactile sensation, wearing comfort and usability. On the other hand, when tension is applied more than 60 times, the thread wound around the straight metal wire is easy to stretch and the tension cannot be dispersed to the thread, resulting in the metal wire. Tends to be disconnected. It is appropriate to use 1 to 3 threads 1b. If the number of threads exceeds three, the thread becomes thicker and the knitting processability is inferior, and the wearing comfort tends to be rugged. As described above, the coating fiber 2 is wound around the core material 1 composed of the thin metal wire 1a and the thread 1b wound around the thin metal wire 1a to form the coating layer 3. The coating fiber 2 is not particularly limited, but is determined in consideration of knitting workability, resin coating workability, product tactile sensation, touch, fit and the like, usability, hygroscopicity and the like. From this point of view, examples of the coating fiber 2 include polyethylene, polyaramid, polyester, polyamide (nylon), acrylic, cotton, and wool. The coating fiber 2 may be a multifilament, or may be a twisted yarn or a spun yarn. Among these, polyester, polyamide (nylon), cotton and wool are particularly preferable, and in spun yarn, cotton or polyester is preferable in that it is soft. Further, as the coating fiber 2, the filament is preferably crimped, and the crimped polyester fiber or polyamide fiber is particularly preferable because it has a good texture.

0012The thickness of the coating fiber 2 may be appropriately determined depending on the intended use of the obtained composite fiber, etc., but is usually 50 to 500 denier from the viewpoint of preventing surface exposure of the fine metal wire 1a, wearing comfort of the knitted product, and usability. About (100 to 10th) is preferable, and about 50 to 300 denier (100 to 15th) is more preferable. In the case of a coated fiber composed of filaments, the number of filaments is preferably 20 to 500 filaments. If it is less than 20 filaments, the thickness of the filament tends to be large and it tends to be stiff, while if it exceeds 500 filaments, it becomes expensive and is not preferable. The coating fiber 2 is wrapped around the core material 1. The number of layers around which the coating fiber 2 is wound may be appropriately selected depending on the intended use of the obtained composite fiber, but if the number of layers is small, the effect of coating the core material 1 becomes insufficient, and the core material is outside the coating layer 3. On the other hand, if the number of layers is large, the knitting workability of the composite fiber is lowered, and a stiff feeling is generated, which tends to lower the wearing comfort and the usability. Therefore, two layers are preferable. When the composite fiber 2 is wound around the two layers, as shown in FIG. 1, the coating fiber 2a of the first layer is wound in the opposite direction to each other, that is, in the same figure, the coating fiber 2a of the first layer is wound in the clockwise direction, and the composite fiber of the second layer is wound. 2b is wound in the counterclockwise direction to form the first coating layer 3a and the second coating layer 3b, respectively. In FIG. 1, the winding of the thread 1b around the thin metal wire 1a is omitted. The number of times the coated fiber 2 is wound may be appropriately determined depending on the intended use of the obtained coated fiber and the like, but is preferably 300 to 1200 times, more preferably 450 to 1000 times per 1 m of the length of the core material 1. If it is less than 300 times, the purpose of preventing the surface exposure of the thin metal wire 1a is not sufficiently achieved, while if it exceeds 1000 times, the composite fiber becomes hard, which is not preferable. It is appropriate that the coating fiber 2 has 1 to 6 fibers per layer. If the number of fibers exceeds 6, the process tends to be complicated when producing the composite fiber, and a stiff feeling is likely to occur, which is not preferable.

0013The composite fibers obtained as described above can be used as various safety protective products such as safety protective cloths, protective clothing, protective aprons, and protective gloves by using a normal knitting machine. Suitable for cut resistant gloves. When knitting the composite fiber of the present invention to produce a cut-resistant glove, plating is performed using a fiber having a good touch and feel and abundant hygroscopicity, and the plated fiber is knitted so as to be inside the glove. By doing so, it is possible to provide a cut-resistant glove that is comfortable to wear and feels good to the touch and has excellent hygroscopicity.

0014Examples of such plating fibers include composite fibers of at least one synthetic fiber selected from polyamide, polyethylene, polyester, polyphenylene terephthalamide, and rayon and polyurethane, polyamide, polyethylene, polyester, polyphenylene terephthalamide, and rayon. Synthetic fibers and natural fibers such as cotton are suitable. The plating fiber may be appropriately determined depending on the intended use, but a plurality of types of fibers may be used. The thickness of the plating fiber is preferably 50 to 700 denier, more preferably 50 to 550 denier, from the viewpoint of comfort and workability. If it is less than 50 denier, the effect of plating tends to be insufficient, and if it exceeds 700 denier, the knitting density of the plating yarn tends to increase and the knitting workability tends to decrease. The number of plating fibers may be appropriately determined, but is preferably about 1 to 7 fibers, more preferably 1 to 5 fibers, from the viewpoint of ease of plating processing.
