Description

[Technical Field]

[0001] The present invention relates to gloves that have not only sufficient anti-slip properties but also excellent cut resistance and low dust generation, even without providing anti-slip properties by coating the outer layer (surface layer facing the outside air) with a resin such as vinyl chloride or rubber. [Background technology]

[0002] Conventionally, gloves made of para-aramid fibers have been proposed as gloves worn for preventing danger during hard work or general use (for example, Patent Document 1, Patent Document 2, and Patent Document 3). However, although such work gloves have excellent cut resistance, they have the problem of being slippery when carrying heavy objects.

[0003] On the other hand, gloves that focus on anti-slip effect include work gloves with anti-slip materials such as natural rubber, PVC, or silicone resin blocks on the palm, and rubberized gloves that are coated with rubber, but these have problems with cut resistance. Gloves that address both of these problems have been proposed (for example, Patent Document 4), but they are still not satisfactory.

[0004] Furthermore, gloves using liquid crystalline polymer fibers have been proposed as work gloves that combine excellent cut resistance and low dust generation (for example, Patent Document 5), but there is a problem in that sufficient anti-slip effect cannot be obtained due to the use of high-strength filament yarns.

[0006] The present invention has been made in consideration of the above-mentioned background, and an object of the present invention is to provide a glove that not only has anti-slip properties but also has excellent cut resistance and low dust generation. [Means for solving the problem]

[0007] As a result of intensive research to achieve the above object, the inventors have found that gloves having not only anti-slip properties but also excellent cut resistance can be obtained by skillfully devising the type and diameter of fibers constituting the gloves, and have completed the present invention through further intensive research.

[0008] Thus, according to the present invention, "gloves containing two or more kinds of fibers, including polyester filament yarns consisting of ultrafine fibers with a single fiber diameter of 1000-2000 nm and a number of filaments of 800 or more, and high-strength polyethylene fibers and stainless steel fibers as high-strength fibers, are generated by the tumble method according to JIS B 9923 and measured with a particle counter, and the number of particles having a particle diameter of 0.5 μm or more is 1500 particles / ft per pair of gloves." 3 is as follows: The fabric weight of the gloves is 200-600g / m 2 The thickness of the fabric that makes up the glove is within the range of 0.7 to 3.0 mm, and the fabric that makes up the glove is level 5 in the EN388 2003 cut resistance test. "Gloves characterized by:

[0009] In that case, glovesPreferably, the glove contains a composite yarn containing the ultrafine fiber and high-strength fiber. The glove also preferably contains polyester filament yarn and / or elastic fiber having a single fiber diameter of 5 to 40 μm. In this case, the weight ratio of the fibers constituting the glove is preferably 10 to 50% by weight of polyester fiber, 87 to 35% by weight of high-strength fiber, and 3 to 15% by weight of elastic fiber. The ultrafine fiber is preferably disposed in the outer layer (outside air surface layer) and inner layer (hand surface layer) of the glove.

[0010] The glove of the present invention It is preferable that the static friction resistance of at least one surface of the fabric constituting the glove is 0.5 N or more. It is also preferable that the glove is used for any purpose selected from the group consisting of automobile parts manufacturing, electronic parts manufacturing, iron and steel, welding, machining, transportation, moving, waste disposal, cleaning, agriculture, fisheries, meat processing, gardening, and outdoors. [Effects of the Invention]

[0011] According to the present invention, gloves can be obtained which not only have anti-slip properties but also have excellent cut resistance and low dust generation. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 2 is a diagram schematically illustrating a method for measuring a frictional resistance value. DETAILED DESCRIPTION OF THE INVENTION

[0013] DETAILED DESCRIPTION OF THE INVENTION The glove of the present invention contains ultrafine fibers having a single fiber diameter of 500 to 3000 nm and high-strength fibers. Here, it is essential that the ultrafine fibers (sometimes referred to as "nanofibers") have a single fiber diameter (diameter of a single fiber) within the range of 500 to 3000 nm (preferably 700 to 2500 nm, and particularly preferably 1000 to 2000 nm). A single fiber diameter smaller than 500 nm is not practically preferable because the fiber strength decreases and the single fiber itself is cut and generates dust. Conversely, a single fiber diameter greater than 3000 nm is not preferable because it may not provide anti-slip performance. Here, when the cross-sectional shape of the single fiber is an irregular cross-section other than a circular cross-section, the diameter of the circumscribed circle is taken as the single fiber diameter. The single fiber diameter can be measured by photographing the cross section of the fiber with a transmission electron microscope.

[0014] The fiber form of the ultrafine fibers is not particularly limited, but is preferably a long fiber (multifilament). The cross-sectional shape of the single fiber is also not particularly limited, and may be any known cross-sectional shape such as round, triangular, flat, hollow, etc. In addition, it does not matter if the fiber has been subjected to ordinary air processing or false twist crimping processing. In order to obtain anti-slip properties and a soft feel, it is important that the ultrafine fibers are multifilaments having 800 or more fibers (preferably 800 to 10,000 fibers).

[0015] The type of polymer forming the ultrafine fibers is not particularly limited, but polyester-based polymers, nylon-based polymers, or polyphenylene sulfide are preferred. Preferred examples of polyester-based polymers include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, and polyesters copolymerized with a third component. Such polyesters may be material-recycled or chemically recycled polyesters. Furthermore, polyesters obtained using catalysts containing specific phosphorus compounds and titanium compounds, as described in JP-A Nos. 2004-270097 and 2004-211268, polylactic acid, and stereocomplex polylactic acid may also be used. The polymer may optionally contain one or more of the following within the scope of the present invention: a micropore-forming agent, a cationic dye-dyeable agent, a coloring inhibitor, a heat stabilizer, a fluorescent brightener, a matting agent, a colorant, a moisture absorbent, and inorganic fine particles.

[0016] On the other hand, the high strength fiber contained in the glove of the present invention is not particularly limited in its fiber form, but is preferably a long fiber (multifilament). When the high-strength fiber is a long fiber (multifilament), the total fineness is preferably within the range of 110 to 1,800 dtex (preferably 300 to 1,100 dtex). If the total fineness is less than 110 dtex, the resulting glove may be too thin, resulting in reduced cut resistance. Conversely, if the total fineness is greater than 1,800 dtex, the resulting glove may be too thick, making delicate work difficult. In the case of a long fiber (multifilament), the number of filaments is not particularly limited, but to obtain cut resistance and a soft feel, it is preferable that the number be 10 to 1,200 (more preferably 50 to 1,000). The cross-sectional shape of the single fiber is also not particularly limited, and may be any known cross-sectional shape such as round, triangular, flat, or hollow. Conventional air processing and false twist crimping may also be performed.

[0017] The type of fiber used as the high-strength fiber is preferably at least one of high-strength polyethylene fiber, polyparaphenylene benzoxazole fiber, polyarylate fiber, para-aramid fiber, carbon fiber, glass fiber, stainless steel fiber, and metal fiber. Specific examples of high-strength polyethylene fiber include "Dyneema (trade name)," "Izanas (trade name)," "Tsunuga (trade name)," and "ENDUMAX (trade name)." Specific examples of polyparaphenylene benzoxazole fiber include "Zylon (trade name)." Specific examples of polyarylate fiber include "Vectran (trade name)" and "Zexion (trade name)." Specific examples of para-aramid fiber include "Technora (trade name)," "Twaron (trade name)," and "Kevlar (trade name)."

[0018] The glove of the present invention preferably further contains polyester filament yarn A having a single fiber diameter of 5 to 40 μm. When a work glove contains a yarn containing the ultrafine fibers and polyester filament yarn A having a single fiber diameter of 5 to 40 μm, the shape retention of the yarn is improved, which is preferable. For example, a composite yarn obtained by air-mixing the ultrafine fibers and polyester filament yarn A using an interlace air nozzle, a composite yarn obtained by subjecting the ultrafine fibers and polyester filament yarn A to composite false twist crimping, or a composite yarn obtained by covering polyester filament yarn A with the ultrafine fibers, is also suitable. For example, a composite yarn in which the ultrafine fibers are arranged in the sheath and another fiber such as polyester filament yarn A is arranged in the core is also preferable.

[0019] Here, if the single fiber diameter of the polyester filament yarn A is less than 5 μm, the shape retention of the yarn may be impaired. If the single fiber diameter is more than 40 μm, a soft feel may not be obtained. Here, if the cross section of the single fiber is an irregular cross section other than a circular cross section, the diameter of the circumscribed circle is taken as the single fiber diameter. Note that, as described above, the single fiber diameter can be measured by photographing the cross section of the fiber with a transmission electron microscope.

[0020] The number of filaments in the polyester filament yarn A is not particularly limited, but is preferably in the range of 1 to 400. The fiber form of the polyester filament yarn A is not particularly limited, and it may be a spun yarn, but it is preferable to use a long fiber (multifilament). The cross-sectional shape of the single fiber is also not particularly limited, and may be a known cross-sectional shape such as round, triangular, flat, hollow, etc. It may also be subjected to ordinary air processing or false twist crimping processing, and may be a combination of multiple filament yarns B, C, D, E, etc., with different finenesses and types in addition to the polyester filament yarn A.

[0021] Preferred examples of the polymer forming the polyester filament yarn A include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, and polyesters copolymerized with a third component. Such polyesters may be material- or chemically-recycled polyesters. Furthermore, polyesters, polylactic acids, and stereocomplex polylactic acids obtained using catalysts containing specific phosphorus compounds and titanium compounds, as described in JP-A Nos. 2004-270097 and 2004-211268, may also be used. The polymer may contain one or more of the following as needed, within the scope of the present invention: a micropore-forming agent, a cationic dye-dyeable agent, a coloring inhibitor, a heat stabilizer, a fluorescent brightener, a matting agent, a colorant, a moisture absorbent, and inorganic fine particles.

[0022] The glove of the present invention preferably further contains elastic fiber. The fiber forming the elastic fiber is preferably a polyamide, polyurethane or polyester elastic fiber. In particular, an elastic yarn called FTY (Filament Twisted Yarn) is more preferred, which has a polyurethane core and a nylon or polyester sheath covering.

[0023] Here, the weight ratio (polyester fiber:high strength fiber:elastic fiber) of polyester fiber, high strength fiber, and elastic fiber (composite yarn containing elastic fiber) is preferably within the range of 10:87:3 to 50:35:15. If the weight ratio of polyester fiber is less than this range, the anti-slip performance may be insufficient. Conversely, if it exceeds this range, the cut resistance may be reduced. If the weight ratio of high strength fiber is less than this range, the cut resistance may be insufficient. Furthermore, if the weight ratio of elastic fiber is less than this range, the stretchability may be reduced, making it difficult to put on and take off the glove. Conversely, if it exceeds this range, the cut resistance may be insufficient. In particular, it is preferable that the weight of high strength fiber is 45 to 87 wt% (more preferably 50 to 85 wt%) of the glove weight.

[0024] In the glove of the present invention, it is preferable that the ultrafine fibers are arranged in the outer layer (outside air side surface layer) and the inner layer (hand side surface layer) of the work glove. In particular, it is preferable that the glove has a multi-layer structure in which polyester fibers and high-strength fibers are arranged in both the outer layer (outside air side surface layer) and the inner layer (hand side surface layer) of the glove.

[0025] The glove of the present invention can be manufactured, for example, by the following manufacturing method. First, an islands-in-sea type composite fiber (fiber for ultrafine fiber) formed of a sea part and an island part is prepared. As such an islands-in-sea type composite fiber, an islands-in-sea type composite multifilament fiber (number of islands: 100 to 1500) disclosed in JP 2007-2364 A is preferably used.

[0026] That is, preferred sea component polymers are polyesters, polyamides, polystyrenes, polyethylenes, and the like, which have good fiber-forming properties. For example, preferred polymers that are readily soluble in aqueous alkaline solutions are polylactic acid, ultra-high molecular weight polyalkylene oxide condensation polymers, polyethylene glycol compound copolymer polyesters, and copolymer polyesters of polyethylene glycol compounds and 5-sodium sulfonate isophthalic acid. Among these, preferred is a polyethylene terephthalate copolymer polyester having an intrinsic viscosity of 0.4 to 0.6, which is obtained by copolymerizing 6 to 12 mol % of 5-sodium sulfoisophthalic acid with 3 to 10 wt % of polyethylene glycol having a molecular weight of 4,000 to 12,000.

[0027] On the other hand, the island component polymer is preferably a polyester polymer, a nylon polymer, or polyphenylene sulfide. Among these, fiber-forming polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, and polyesters copolymerized with a third component are preferred. The polymer may optionally contain one or more of the following within the scope of the present invention: a micropore-forming agent, a cationic dye-dyeable agent, a coloring inhibitor, a heat stabilizer, a fluorescent whitening agent, a matting agent, a colorant, a moisture absorbent, and inorganic fine particles.

[0028] In the islands-in-sea type composite fiber composed of the above sea part polymer and island part polymer, the melt viscosity of the sea part during melt spinning is preferably higher than the melt viscosity of the island part polymer. The diameter of the island parts must be in the range of 500 to 3,000 nm. If the shape of the island parts is not a perfect circle, the diameter of the circumscribed circle is determined. In the islands-in-sea type composite fiber, the sea-island composite weight ratio (sea:island) is preferably in the range of 40:60 to 5:95, and more preferably in the range of 30:70 to 10:90.

[0029] Such islands-in-sea composite fibers can be easily produced, for example, by the following method. That is, the sea part polymer and island part polymer are melt-spun. Any spinneret can be used for melt spinning, such as one having a group of hollow pins or a group of fine holes for forming island parts. The extruded islands-in-sea composite fiber is solidified by cooling air and melt-spun at a speed of preferably 400 to 6,000 m / min, and then wound up. The resulting undrawn yarn can be made into a composite fiber (drawn yarn) having the desired strength, elongation, and heat shrinkage properties through a separate drawing process, or it can be taken up on a roller at a constant speed without being wound up, and then drawn and wound up afterwards. In such islands-in-sea composite fibers, the single fiber fineness, number of filaments, and total fineness are preferably within the ranges of 0.5 to 10.0 dtex, 5 to 75 filaments, and 30 to 170 dtex, respectively.

[0030] Next, a yarn is produced using the islands-in-sea composite fiber and, if necessary, polyester filament yarn A. When polyester filament yarn A is used, it is preferable to produce a composite yarn having a three-layer structure in which polyester filament yarn A is arranged in the middle layer so that the polyester filament yarn A is less likely to be exposed on the surface of the composite yarn, or to produce a composite yarn in which the islands-in-sea composite fiber is located in the sheath and the polyester filament yarn A is located in the core. There are no limitations on the machine used, and a conventionally known blending machine, false twist crimping machine, or covering machine may be used. The obtained composite yarn may also be twisted at 500 turns / m or less.

[0031] The yarn is then treated with an alkaline aqueous solution to dissolve and remove the sea component of the islands-in-sea type composite fibers, thereby converting the islands-in-sea type composite fibers into ultrafine fibers. The alkaline aqueous solution treatment is preferably performed using a 1 to 4% NaOH aqueous solution at a temperature of 55 to 98°C.

[0032] The yarn may be dyed before and / or after dissolution and removal with the alkaline aqueous solution. Furthermore, various types of finishes may be additionally applied, such as conventional nap raising and water repellent finishes, as well as finishes that impart functions such as ultraviolet shielding, antistatic agents, antibacterial agents, deodorizing agents, insect repellents, luminescent agents, retroreflective agents, and negative ion generators.

[0033] Next, the yarn and the high-strength fiber are twisted or covered to obtain a composite yarn. The composite yarn and, if necessary, an elastic fiber (or a composite yarn of an elastic fiber and another fiber) are knitted or woven to produce gloves. The gloves may be produced on a glove knitting machine, or the knitted or woven fabric may be sewn after the gloves are obtained.

[0034] In the work gloves thus obtained, the fabric weight of the constituent fabric is 200 to 600 g / m 2 (More preferably 300 to 500 g / m 2 It is preferable that the basis weight is within the range of 200 g / m 2 If the basis weight is less than 600 g / m, the cut resistance is insufficient. 2 If it is larger, it may become too hard and make fine work difficult.

[0035] Furthermore, in the gloves of the present invention, the thickness of the fabric constituting the gloves is preferably within the range of 0.7 to 3.0 mm (more preferably 1.0 to 2.5 mm). If the thickness is less than 0.7 mm, the cut resistance may be insufficient. Conversely, if the thickness is more than 3.0 mm, the gloves may be too thick and may make delicate work difficult. Furthermore, if the thickness is too great, the gloves of the present invention may not be able to be worn under disposable gloves.

[0036] Next, the gloves of the present invention preferably have a cut resistance level of 2 or higher (more preferably 3 or higher) in the EN388 2003 cut resistance test. In addition, when dust is generated by the JIS B 9923 tumble method and measured with a particle counter, the number of particles with a particle size of 0.5 μm or more generated is 1500 particles / ft per pair of gloves. 3It is preferable that the static friction force of the outer layer (surface facing the outside air) of the glove is 0.5N or more. If it is less than this level in the cut resistance test, there is a risk that the cut resistance will be insufficient. In addition, the number of particles generated should be 1500 particles / ft 3 If the static friction resistance exceeds 0.5N, workability may be impaired. Also, if the static friction resistance is less than 0.5N, the surface may become slippery and workability may be impaired. Note that 1 ft is 30.48 cm.

[0037] The glove of the present invention is preferably used for any application selected from the group consisting of automobile parts manufacturing, electronic equipment parts manufacturing, iron and steel, welding, machining, transportation, moving, waste disposal, cleaning, agriculture, fisheries, meat processing, gardening, and outdoor activities. Since such a glove has the above-mentioned constitution, it has excellent cut resistance, excellent anti-slip properties, and low dust generation. [Example]

[0038] Examples and comparative examples of the present invention will be described in detail below, but the present invention is not limited to these. The measurement items in the examples were measured by the following methods.

[0039] <Melt viscosity> The dried polymer was placed in an orifice set to the melt temperature of the ruder during spinning, and after being held in the melt for 5 minutes, it was extruded under several load levels, and the shear rate and melt viscosity were plotted. The plots were smoothly connected to create a shear rate-melt viscosity curve, and the shear rate was 1000 s -1 The melt viscosity was measured at this time.

[0040] <Dissolution rate> The sea and island component yarns were wound at a spinning speed of 1000-2000 m / min using a 0.3φ-0.6L×24H spinneret, and then drawn to a residual elongation of 30-60% to produce multifilament yarns with a total fineness of 84 dtex / 24fil. The weight loss rate was calculated from the dissolution time and amount of dissolved yarn in each solvent at the intended temperature and bath ratio of 100.

[0041] <Single fiber diameter> After photographing the fabric with an electron microscope, the single fiber diameter was measured for an n number of 5 and the average value was calculated.

[0042] <Weight ratio of polyester fiber to aramid fiber> A square sample of 3 cm x 3 cm was cut out, and the weights of the polyester yarn and aramid fiber contained in the sample were measured to determine their weight ratio.

[0043] <Metsuke> Measurement was carried out in accordance with JIS L 1096 6.4.2.

[0044] <Thickness> Measurement was carried out in accordance with JIS L 1096 8.5.

[0045] <Cutting force> Measurements were carried out in accordance with EN388 2003, and a passing grade of level 2 or above was achieved.

[0046] <Dust generation> Without cleaning one pair of gloves (one for each hand), dust was generated by the tumbling method of JIS B9923-1997, and the number of particles of each particle size or larger was measured using a particle counter. The measurement was carried out twice, and the average value was taken as the amount of dust generated, which was 1500 particles / ft 3 The following were considered successful:

[0047] <Static friction resistance value> As shown in Figure 1, a stainless steel plate was placed on a smooth table under an environment of 20°C temperature and 65% RH humidity. A head measuring 5cm x 8cm at the bottom, 3cm high, and weighing 150g (147cN) with a sample attached to its underside was then placed on the plate. The static friction resistance was measured when the head was pulled at a speed of 100mm / min using a tensile tester. A static friction resistance of 0.5N or more was considered satisfactory.

[0048] [Example 1] The island component was polyethylene terephthalate (melt viscosity at 280°C: 1200 poise, matting agent content: 0 wt%), and the sea component was polyethylene terephthalate copolymerized with 6 mol% of 5-sodium sulfoisophthalic acid and 6 wt% of polyethylene glycol having a number average molecular weight of 4000 (melt viscosity at 280°C: 1750 poise) (dissolution rate ratio (sea / islands) = 230). An islands-in-sea type composite undrawn fiber with a sea:islands ratio of 30:70 and the number of islands = 90 was melt spun at a spinning temperature of 280°C and a spinning speed of 1500 m / min, and then temporarily wound up.

[0049] The obtained undrawn yarn was roller drawn at a drawing temperature of 80°C and a draw ratio of 2.5, then heat-set at 150°C and wound up. The obtained islands-in-sea type composite fiber (fiber for ultrafine fibers, drawn yarn) had a total fineness of 56 dtex / 27 fil, and observation of the fiber cross section with a transmission electron microscope (TEM) revealed that the islands had round shapes and a diameter of 1400 nm.

[0050] Two of the resulting islands-in-sea composite fibers were aligned with one polyethylene terephthalate multifilament (total fineness 56 dtex / 48 fil; single fiber diameter 11 μm, polyester multifilament yarn A), and then subjected to composite false twist crimping to obtain a polyester yarn. Next, in order to remove the sea component of the islands-in-sea composite fiber contained in the polyester yarn, the polyester yarn was subjected to 25% weight reduction (alkali weight reduction) in a 2.0% NaOH aqueous solution at 70°C. The obtained polyester yarn was composed of ultrafine fibers with a single fiber diameter of 1400 nm and polyester filament yarn A with a single fiber diameter of 11 μm, and had a total fineness of 157 dtex.

[0051] On the other hand, as high-strength fibers, one strand of Tsunouga (product name) manufactured by Toyobo Co., Ltd. with a total fineness of 440 dtex / 360 fil (multifilament) and one strand of stainless steel fiber (30 μm diameter) were prepared, and the two were aligned and twisted with an S twist of 600 T / m to obtain a twisted yarn. Next, the twisted yarn and one of the polyester yarns were Z-twisted at 300 T / m to cover the yarn, resulting in a total fineness of 880 dtex. In addition, one yarn (composite yarn containing elastic fiber) was prepared in which polyurethane elastic fiber (total fineness 84 dtex) was covered with nylon processed yarn 110 dtex.

[0052] Next, plating knitting was carried out using the 880 dtex yarn and a yarn in which polyurethane elastic fiber was covered with nylon processed yarn, and gloves were knitted using a 10 gauge glove knitting machine (manufactured by Shima Seiki Co., Ltd.) so that the polyester yarn and high strength fiber were positioned in the outer layer (surface layer facing the outside air) and inner layer (surface layer facing the hand). After knitting, the gloves were washed for 20 minutes in hot water at 60°C containing 2 g of nonionic surfactant per liter of water, and then dehydrated and dried to obtain the desired work gloves.

[0053] In the obtained gloves, the weight ratio of the composite yarn containing polyester fiber, high strength fiber, and elastic fiber was 12:78:10 in this order, and the basis weight was 500 g / m 2 The thickness was 1.6 mm. The cut resistance was level 5, providing excellent protection, and the dust generation rate was 850 particles / ft 3 It also had excellent low dust generation properties and a static friction resistance of 0.6N, making it excellent in anti-slip performance.

[0054] [Example 2] A 77-dtex polyurethane elastic yarn was covered with one 167-dtex polyester textured yarn at a Z twist of 300 T / M to obtain a covered yarn. Next, the covered yarn was again covered with the polyester yarn used in Example 1 at an S twist of 350 T / M to obtain a double-covered yarn.

[0055] Next, the double-covered yarn and one strand of Tsunouga (trade name) manufactured by Toyobo Co., Ltd., which was used in Example 1 and had a total fineness of 440 dtex / 360 fil (multifilament), were plate-knitted, and gloves were knitted using a 13-gauge glove knitting machine (manufactured by Shima Seiki Co., Ltd.) so that the double-covered yarn and the high-strength fiber were positioned in the outer layer (surface layer facing the outside air) and inner layer (surface layer facing the hand).

[0056] In the obtained gloves, the weight ratio of the composite yarn containing polyester fiber, high strength fiber and elastic fiber was 40:55:5 in this order, and the basis weight was 450 g / m 2 The thickness was 1.5 mm. The cut resistance was level 3, providing excellent protection, and the dust generation rate was 900 particles / ft 3 It also had excellent low dust generation properties and a static friction resistance of 0.56N, making it excellent in anti-slip performance.

[0057] [Example 3] The polyester yarn used in Example 1 and a para-aramid fiber (manufactured by Teijin Limited under the trade name Technora) as a high-strength fiber with a total fineness of 440 dtex / 263 fil (multifilament) were prepared.

[0058] Using five of the polyester yarns, two of the para-aramid fibers, and one yarn of polyurethane elastic fiber (total fineness 22 dtex) covered with nylon-processed yarn 77 dtex / 24 fil, gloves were knitted using the glove knitting machine of Example 1 so that the polyester yarn was located in the outer layer (surface layer facing the outside air) and the para-aramid fiber and the yarn of polyurethane elastic fiber covered with nylon-processed yarn were located in the inner layer (surface layer facing the hand).

[0059] The weight ratio of the polyester yarn to the composite yarn containing high strength fiber and elastic fiber in the obtained glove was 42:50:8, and the weight was 486 g / m 2 The static friction resistance was 0.7N, providing excellent anti-slip performance, and the dust generation rate was 1,450 particles / ft 3 It has excellent low dust generation and its cut resistance was level 2.

[0060] [Comparative Example 1] Everything was the same as in Example 1 except that the polyester yarn used in Example 1 was replaced with 167 decitex polyester textured yarn.

[0061] The weight ratio of the resulting gloves to the composite yarn containing polyester processed yarn, high strength fiber, and elastic fiber was 13:77:10, in that order, and the weight was 510 g / m 2The thickness was 1.6 mm. The cut resistance was level 5, providing excellent protection, and the dust generation rate was 400 particles / ft 3 However, the static friction resistance was 0.3N, which meant poor anti-slip performance, and the gloves were extremely difficult to work with. [Industrial Applicability]

[0062] According to the present invention, gloves having excellent cut resistance, anti-slip properties and low dust generation are provided, and the industrial value thereof is extremely great. [Explanation of symbols]
