Description

Technical Field

[0001] The present invention relates to cut-resistant gloves. More specifically, the present invention relates to cut-resistant gloves that suppress the amount of dust generated from yarns during yarn manufacturing and knitting.

Background Art

[0002] Yarns containing elastic yarns and cut-resistant yarns, yarns having talc on the yarn surface, or composite yarns having a randomly intertwined loop structure are known as yarns that can impart texture and cut resistance to knitted fabrics (for example, Patent Documents 1 and 2). Examples of the yarn include fibers such as aramid, high molecular weight polyethylene, high molecular weight polyvinyl alcohol, and high molecular weight polyacrylonitrile. However, in Patent Documents 1 and 2, an elastic yarn and an aramid filament yarn or an aramid crimped yarn are simultaneously overfed. Therefore, in Cited Document 1, an operation of applying tension to the elastic yarn is required, and in Patent Document 2, two types of twisted yarns (S and Z) are required to prevent twisting during knitting.

[0003] Even in the case of a cut-resistant yarn that does not contain an elastic yarn, it is known that gloves knitted with a yarn having loops or talc on the surface fit well on the body, have good workability, and can suppress the generation of lint and dust (Patent Document 3). Examples of the cut-resistant yarn include heat-resistant fibers such as aramid fiber, polyparaphenylene benzobisoxazole fiber, polybenzimidazole fiber, polyamideimide fiber, and polyimide fiber.

[0004] However, in the case of the yarn of Patent Document 3, since a multifilament yarn having a kink band that hardly generates lint and dust is used, a pretreatment for imparting a kink band is required. Specifically, a twisted multifilament yarn is heat-set using high-temperature and high-pressure steam and then untwisted, or the multifilament yarn is temporarily twist-crimped at a high temperature and then subjected to relaxation heat treatment. Therefore, although the generation of lint and dust can be suppressed, an untwisting step of untwisting the yarn twisted before knitting is essential, and the yarn is easily twisted during knitting (the knitting property is poor).

[0005] There is also a known method of knitting gloves using a composite yarn in which an elastic yarn (core yarn) is coated with a cut-resistant yarn (sheath yarn) to suppress dust generation from the gloves (Patent Document 4). Examples of the cut-resistant yarn include fibers such as aramid fiber and polyparaphenylene benzobisoxazole fiber in which liquid crystalline polymer fibers are present on the yarn surface. Compared with the coated yarn using a spun yarn for the sheath yarn, the composite yarn has an advantage in that it is less likely to generate lint and dust that are the sources of dust generation. However, since a false-twist processed yarn is used as the cut-resistant yarn, a process of untwisting the false-twist processed yarn is required, and two types of twisted yarns (S and Z) are required to prevent twisting during knitting.

[0006] The gloves described in Patent Document 4 have a certain value or less for the number of dust generation particles having a particle size of 0.5 μm or more, but in the ISO standard, particles of 0.1 μm or more are the standard. 。 Currently, for gloves used in assembly factories for electronic components and precision components, operating rooms, treatment rooms, etc., in addition to cut resistance, a cleanliness class of 5 (the number of fine particles of 0.1 μm or more is 100,000 or less ) The above low dust generation property is desired.

[0007] It is also known to knit protective gloves with a fluid processed yarn of ultra-high molecular weight polyethylene fiber or polyketone fiber that is relatively unlikely to generate lint (Patent Documents 5 and 6). However, the cut resistance and low dust generation property of gloves knitted with organic fiber yarns are in an inverse relationship, and are also affected by the material of the yarn (properties of the yarn), processing method (properties of the yarn), knitting method of the gloves, etc. Therefore, it is currently difficult to obtain gloves that have both cut resistance and low dust generation property and also satisfy the fitting feeling (wearability) during wearing.

[0009] The present invention has been made in view of the background of such prior art, and an object thereof is to provide gloves capable of simplifying the yarn manufacturing process, having good knitting properties, excellent cut resistance and low dust generation properties, and a method for manufacturing the gloves.

Means for Solving the Problems

[0010] In order to solve the above problems, the present inventors have conducted intensive studies. Based on the findings obtained from the examination of gloves and various yarns used therein, that is, even when using yarns of the same material, the knitting properties and cut resistance of the gloves differ depending on the difference in the yarn manufacturing method, and although the details of the dust generation mechanism of the gloves are unknown, it has been made based on the finding that gloves knitted with fibers processed by fluid injection have a value of 100,000 or less (per two gloves) for the number of dust particles with a particle size of 0.1 μm or more when dust is generated by the tumbling method.

[0011] That is, the present invention provides: (i) at an overfeed rate of 3 to 10% Gloves knitted with a single or multiple yarns of a fiber yarn having a fineness of 600 to 1,200 dtex consisting only of organically fiber processed by fluid injection (excluding elastic fibers), Or, (ii) Gloves knitted with a ground yarn made of the above yarn and an elastic filling yarn having a fineness of 30 to 190 dtex. and the gloves of (i) and (ii) are the number of set gauges during knitting is 7 gauges to 15 gauges, having a basis weight in the range of 200 to 750 g / m 2 and simultaneously satisfying the following (1) and (2), and the organic fiber is an organic fiber having a tensile strength of 17.5 cN / dtex or more Provided is a cut-resistant glove characterized by the above. (1) When dust is generated by the JIS B 9923 tumbling method and measured with a particle counter, the number of dust particles having a particle size of 0.1 μm or more is 40,000 per two gloves / m 3 shows the following value. (2) The value of the cutting load measured by the JIS T 8052 Protective clothing - Mechanical properties - Cut resistance test against sharp objects is in the range of 7 to 15 N.

[0012] In addition, the present invention (i) A yarn formed by aligning a single or a plurality of fiber yarns with a fineness of 600 to 1,200 dtex, which is composed only of organically fiber processed by fluid injection (however, does not include elastic fibers), or (ii) A ground yarn made of the yarn and and the fineness is 30 to 190 dtex a stretch adding yarn are fed to a glove knitting machine with a gauge number set to 7 to 15 gauges, and knitted through a tension adjuster in which the contact surface with the yarn is formed in a matte finish, and the knitted glove simultaneously satisfies the above (1) and (2), and the organic fiber is an organic fiber having a tensile strength of 17.5 cN / dtex or more Provided is a method for manufacturing a cut-resistant glove characterized by the above.

Effect of the Invention

[0013] According to the present invention, the manufacturing process of a fiber yarn consisting only of organic fibers can be simplified, and gloves excellent in knitting property, cut resistance, and low dust generation can be provided. The gloves can be used as work gloves to be used in a clean room where the cleanliness of JIS (ISO) standard class 5 or higher is required. Further, in normal work, it is also suitable as work gloves accompanied by a risk of being cut by a sharp blade or burr.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, the present invention will be described in detail. The cut-resistant glove of the present invention is knitted with a yarn obtained by aligning single or multiple fiber yarns having a fineness of 440 to 1,800 dtex consisting only of fluid-injected organic fibers. The number of aligned yarns is not particularly limited, but is usually 2 to 5, preferably 2 to 3. However, the organic fiber does not contain an elastic fiber. Gloves knitted with a yarn containing an elastic fiber have an advantage of excellent fit when wearing the gloves, but have problems in terms of quality control.

[0016] The basis weight of the cut-resistant glove of the present invention is 200 to 750 g / m 2 If the basis weight is 200 g / m 2 or more, cut resistance can be ensured as work gloves, and if the basis weight is 750 g / m 2 or less, the knitting property is good. The basis weight of the cut-resistant glove is more preferably 240 to 700 g / m 2 and particularly preferably 270 to 700 g / m 2 .

[0017] [Organic Fiber] The organic fiber can be appropriately selected and used from known ones. As the properties of the raw yarn, continuous fibers with a tensile strength of 17.5 cN / dtex or more measured according to JIS L 1013 8.5 are preferably used. When the tensile strength is less than 17.5 cN / dtex, it becomes difficult to impart a high degree of abrasion resistance to the fiber yarn, and there is a risk that the above characteristic value (2) cannot be satisfied. Preferably, it is 17.5 to 35 cN / dtex.

[0018] As the above-mentioned organic fiber, from the viewpoints of tensile strength and abrasion resistance, para-aramid fiber, wholly aromatic polyester fiber, polyparaphenylene benzobisoxazole fiber, polyketone fiber, polyamideimide fiber, ultra-high molecular weight polyethylene fiber, high-strength vinylon fiber, etc. can be mentioned. The organic fiber may be used alone or in combination of two or more. Among these materials, para-aramid fiber and ultra-high molecular weight polyethylene fiber are preferable from the viewpoint of excellent wearing feeling when wearing gloves, and para-aramid fiber is particularly preferable from the viewpoint of excellent cut resistance. The ratio of para-aramid fiber in the organic fiber is preferably 50% by mass or more, more preferably 70 to 90% by mass, and particularly preferably 100% by mass.

[0019] The fineness of the fiber yarn made of organic fiber is 600 to 1,200 dtex. When knitting gloves with a yarn having a fineness of less than 600, if the number of aligned yarns is small, the cut resistance is poor, and if the number of aligned yarns is increased, the productivity of the gloves is poor. On the other hand, when the fineness exceeds 1,200 dtex, the knitting property is poor (the knitting machine cutter is difficult to cut). The fineness of the fiber yarn is 、6 Preferably 600 to 1,000 dtex. The fineness of the single fiber of the organic fiber is preferably 0.1 to 10 dtex, more preferably 0.3 to 6 dtex, and particularly preferably 1.0 to 2.5 dtex. If it is less than 0.1 dtex, the strength of the fiber is too weak and it is difficult to form gloves. On the other hand, if it exceeds 10 dtex, the gloves become hard.

[0020] The above-mentioned organic fibers may be commercially available products. Examples of para-aramid fibers include poly(p-phenylene terephthalamide) fibers (manufactured by Toray DuPont Co., Ltd., trade name "Kevlar" (registered trademark)), copoly(p-phenylene)-3,4'-oxydiphenylene terephthalamide fibers (manufactured by Teijin Limited, trade name "Technora" (registered trademark)), and the like. Among these, poly(p-phenylene terephthalamide) fibers are preferred because of their excellent high strength, high elastic modulus, cut resistance, and heat resistance.

[0021] Examples of wholly aromatic polyester fibers include "Vectran" manufactured by Kuraray Co., Ltd. Examples of poly(p-phenylene benzobisoxazole) fibers include "Zylon" manufactured by Toyobo Co., Ltd. Examples of ultra-high molecular weight polyethylene fibers include "Izanas" and "Tsunuga" manufactured by Toyobo Co., Ltd., "Dyneema" manufactured by DSM, and "Spectra" manufactured by Honeywell.

[0022] [Fluid injection processing] The cut-resistant gloves of the present invention are knitted with fiber yarns of fluid-processed yarns obtained by subjecting organic fibers to fluid injection processing, either singly or in a plurality of aligned yarns. Fluid injection processing is a technique in which a fluid such as water, steam, or air is forcibly sprayed onto the fibers, and the flow thereof disturbs the orientation of the fibers to impart bulkiness. Organic fibers having a tensile strength of 17.5 cN / dtex or more, such as para-aramid fibers, tend to make the knitted gloves hard because of their high tensile elastic modulus. However, by performing fluid injection processing, bulkiness can be imparted without damaging the fiber surface.

[0023] An example of the fluid injection processing method for the organic fibers used in the present invention is shown in FIG. 1. The organic fiber yarn 1 is supplied from the feed roller 2 to the fluid processing nozzle 3, merges with the fluid supplied from another inlet 4 to the fluid processing nozzle 3, is ejected from the fluid processing nozzle 3, and is wound around the take-up bobbin 7 via the delivery roller 5. The organic fiber yarn 1 may be supplied from a single raw yarn bobbin or a plurality of raw yarn bobbins. The organic fiber yarn may be of one type, or two or more different types of materials may be supplied to the fluid processing nozzle and combined.

[0024] In fluid jet processing, by selecting processing conditions such as the overfeed rate, yarn thickness, nozzle shape, fluid pressure, and processing speed, various processed yarns can be obtained according to the application, from a bulky processed yarn with looped flyers to a slightly bulky yarn without looped flyers. Generally, thin yarns (150 dtex or less) are strongly disturbed by fluid jet processing, so the fiber surface of high-strength fibers such as para-aramid fibers may fibrillate. In the present invention, the fineness of the organic fiber yarn is 440 to 1,800 dtex, and it is not easily disturbed by fluid jet processing, so it is difficult to form loops, and the fiber surface is not easily damaged, resulting in a bulky processed yarn in which each yarn has a swelling with a wavy slack shape.

[0025] By processing the organic fiber yarn at an overfeed rate of 3 to 10%, more preferably 3 to 8%, and a fluid jet pressure of 1 MPa or less, a fiber yarn suitable for the cut-resistant gloves of the present invention can be obtained. In addition, fibrillation of the organic fiber and shaving of the fiber surface are suppressed, and it is suppressed that fibril fragments and chips adhere to the gloves. Note that "fibrillation" refers to a phenomenon in which a crack occurs in a single fiber and it splits into finer fibers.

[0026] In the cut-resistant gloves of the present invention, in addition to the fiber yarn made of the above-described organic fiber, known fiber yarns such as nylon and polyester may be included. Known fibers such as nylon and polyester can be included in the yarn at a ratio of less than about 50% by mass, more preferably 10 to 30% by mass, in the form of mixing, filling yarns, etc., as long as the effects (low dust generation property, cut resistance) of the present invention are not inhibited.

[0027] The number of yarns constituting the gloves may be plural as long as it does not inhibit knitting. When knitting with plural yarns, the organic fiber yarn may be partial or total. In some cases, the other yarn may contain known fibers such as nylon and polyester.

[0028] [Knitting of Gloves] The cut-resistant and innovative glove of the present invention can be obtained by feeding only the above-mentioned fiber yarns, either singly or in a plurality of aligned yarns, into a knitting machine and knitting them with a general seamless knitting machine.

[0029] The cut-resistant and innovative glove of the present invention can be obtained by using the above-mentioned fiber yarns, either singly or in a plurality of aligned yarns, as the ground yarn, and feeding the ground yarn and the elastic supplementary yarn through a tension adjuster in which the contact surface with the yarn is pearled, into a computer glove knitting machine SFG or STJ (manufactured by Shimadzu Seiki Co., Ltd.) and performing plating knitting. Plating knitting is also called supplementary yarn knitting and is a fabric knitted using two types of yarns so that one yarn covers the other. The supplementary yarn can be knitted with the ground yarn, and different yarns can be made to appear on the front and back. When knitting the glove, the number of supplementary yarns is preferably 1 to 3, more preferably 1 to 2. Within the range that does not impair the knitting performance, the thickness and texture of the glove, the low dust generation property, and the cut resistance, in addition to the ground yarn and the supplementary yarn, known fibers can be aligned and knitted with any of the above-mentioned yarns.

[0030] In plating knitting, either the ground yarn or the supplementary yarn is knitted so as to be arranged on the outer surface or the inner surface. When knitting with the ground yarn on the outer surface / supplementary yarn on the inner surface, the resulting state is used as the glove. When knitting with the ground yarn on the inner surface / supplementary yarn on the outer surface, the knitted glove is turned inside out / outside in, and finally, the state with the ground yarn on the outer surface / supplementary yarn on the inner surface is used as the glove. By doing so, when wearing the glove, the contact between the cut-resistant ground yarn and the user's skin can be suppressed, and since the elastic supplementary yarn comes into contact with the skin, the wearing comfort and sweat absorption are improved. At the same time, the cut-resistant ground yarn on the outer surface prevents damage to the supplementary yarn on the inner surface from external sharp objects, etc. during work, and the durability of the glove can be enhanced. Regarding the above knitting method, either method can be used depending on the ease of knitting, etc.

[0031] The filling yarn can be appropriately selected and used from known stretchable yarns. For example, wooly-processed yarns of synthetic fiber filaments such as nylon and polyester, covered yarns in which synthetic fiber filaments are helically wound around a core yarn made of polyurethane elastic yarn, fluid mixed yarns of polyurethane elastic yarn and synthetic fiber filaments, etc. may be mentioned. The fineness (measured fineness) of the stretchable filling yarn is not particularly limited, but is preferably 30 to 190 dtex, more preferably 50 to 190 dtex. If it is 30 dtex or more, texture and stretchability can be imparted to the gloves, and if it is 190 dtex or less, the knitting property of the gloves will not deteriorate significantly.

[0032] In the above seamless knitting machine and computerized glove knitting machine, it is preferable to set the set gauge number during knitting to 7 gauges to 15 gauges, and more preferably 7 gauges to 13 gauges. The gauge number is an index representing the number of needles per inch, and the thinner the glove can be obtained as the number increases. If the gauge number is less than 7 gauges, the wearing feeling of the glove is poor, and if it exceeds 15 gauges, it will not serve as a cut-resistant glove.

[0033] After unwinding the yarn for knitting from the package, the main devices existing in the yarn path of the knitting machine include a yarn guide plate, a first tension adjuster, an oil-trailing felt, a yarn break detection spring, and a second tension adjuster. Further, it is guided to the yarn feeder via an overhead spring and finally knitted by the needle. These two tension adjusters are yarn path guides for applying a stable tension to the yarn, and include a washer tenser, a spring tenser, etc.

[0034] As a surface finishing method of the yarn path guide, mirror finishing is common in addition to satin finishing. When the contact surface of the yarn path guide with the yarn is satin-like, the friction with the yarn is reduced, so that in the yarn path guide near the package, fibrillation of organic fibers can be mainly suppressed, and in the subsequent yarn path guide, fragmentation of fibrils of organic fibers or a phenomenon in which the fiber surface is shaved can be suppressed.

[0035] Examples of the material of the contact surface with the yarn of the tension adjuster include, for example, a metal with satin chromium plating; a material coated with ceramics such as titanium, alumina, and titanium carbide, or Teflon (registered trademark), silicon, etc. on the metal; ceramics such as titanium, alumina, and zirconia, etc.

[0036] In the present invention, as a tension adjuster which is a yarn guide for applying tension to the yarn, it is effective to use one having a satin-like contact surface with the yarn. Examples of such a tension adjuster include a component member subjected to satin treatment, or a combination of component members having a satin-like material (for example, the surface of a tension washer is a satin-treated product, and the tensor shaft is a component made of alumina ceramic). When tension is applied to the yarn to stably supply the yarn, it has the effect of preventing the yarn from rubbing and generating a large amount of fibrils and shaving scraps. Furthermore, it is preferable to use a ceramic one for other yarn guides, and a more excellent effect is exhibited.

[0037] In the present invention, by using the above-mentioned yarn and further adjusting the knitting method, when dust is generated by the JIS B 9923 tumbling method and measured with a particle counter, the number of dust emissions with a particle size of 0.1 μm or more is 100,000 per two gloves / m 3 The following values are shown, and a cut-resistant glove can be obtained. The number of dust emissions per two gloves is more preferably 70,000 / m 3 Even more preferably 50,000 / m 3 Even more preferably 40,000 / m 3 The following. The fewer the number of dust emissions, the more desirable.

[0038] Also, JIS T 8052 The cutting load measured in the cut resistance test against sharp objects of Protective clothing - Mechanical properties is in the range of 5 - 15 N. The cutting load is more preferably 6 N or more, even more preferably 7 N or more, and particularly preferably 8 N or more. If the cutting load is less than 5 N, it cannot serve as a work cut-resistant glove. If it exceeds 15 N, the higher the cut resistance, the more resistant it is to blades and burrs, which is good, but the glove becomes hard and the wearing feeling deteriorates.

[0039] On the surface of the low-lint cut-resistant gloves of the present invention, a known coating material of rubber or resin can be applied, thereby making the gloves even lower in dust generation.

Example

[0040] Hereinafter, the present invention will be described more specifically using examples and comparative examples, but the present invention is not limited only to the following examples. The measurement methods of each physical property value in the following examples and comparative examples are as follows.

[0041] [Cutting force and cut resistance (difficulty of cutting)] In accordance with JIS T 8052:2005 "Protective clothing - Mechanical properties - Test method for cut resistance against sharp objects", the cutting force (N) of the palm part of the glove was measured. The cut resistance was obtained by dividing the cutting force (N) by the areal density of the knitted or woven fabric. It was determined that the greater the value of the cutting force, the more difficult it was to cut. The measuring machine used was TDM-100 manufactured by RGI.

[0042] [Evaluation method for dust generation amount] Four gloves were placed in a tumbling type dust generation tester installed in a clean room (cleanliness: ISO class 5) without performing clean washing, and dust was generated by the tumbling method of JIS B 9923-1997 (Method for measuring contaminating particles of clothing for clean rooms), and the number of dust generations of each particle size or more was measured with a particle counter. The number of measurements was 5 times. Excluding the maximum value and the minimum value, the average value of the remaining measured values was converted into the dust generation amount per two gloves. The rotation speed of the drum was 30 revolutions per minute, and the flow rate of the exhaust air was 0.0102 m 3 / s. Also, the number of dust particles (particle number) of 0.1 μm or more in particle size was converted per gram of the weight of two gloves.

[0043] [Evaluation of glove wearing (fit, hardness, prickling feeling)] A wearing test was conducted on 5 subjects. According to 5.2 of EN 420:2003 Protective gloves - General requirements and test methods, all subjects gave a performance evaluation of level 5 in dexterity. And those who were evaluated as "good wearing comfort" by all 5 out of 5 in the sensory evaluation were considered qualified (◎), those who were evaluated as "good wearing comfort" by 3 or more out of 5 were considered qualified (○), and the rest were considered unqualified (×).

[0044] [Ease of knitting gloves] Using glove knitting machines of 7-gauge type, 10-gauge type, 13-gauge type, and 15-gauge type (manufactured by Shimadzu Seisakusho Co., Ltd.), the presence or absence of problems was determined based on the state of the stitches of the knitted gloves after knitting.

[0045] [Production Example 1 (fluid-processed yarn)] Filament yarns of poly(paraphenylene terephthalamide) (hereinafter referred to as PPTA) fibers (manufactured by Toray DuPont Co., Ltd., trade name "Kevlar" (registered trademark)) with a single fiber fineness of 1.67 dtex and a total fineness of 444 dtex, 800 dtex, and 1670 dtex were used. By the taslan method using the fluid injection processing apparatus shown in Fig. 1, the overfeed rate was set to 3 - 10%, and steam was used as the fluid for fluid injection processing to obtain fluid-processed yarns of PPTA filaments. The fluid-processed yarns were made into untwisted yarns.

[0046] [Production Example 2 (fluid-processed yarn)] Using filament yarns of PPTA fibers (manufactured by Toray DuPont Co., Ltd., trade name "Kevlar" (registered trademark)) with a single fiber fineness of 2.5 dtex and a total fineness of 670 dtex, by the taslan method using the fluid processing apparatus shown in Fig. 1, the overfeed rate was set to 3 - 10%, and steam was used as the fluid for fluid injection processing to obtain fluid-processed yarns of PPTA filaments. The fluid-processed yarns were made into untwisted yarns.

[0047] [Production Example 3 (spun yarn)] Staple yarns (single fiber fineness: 1.67 dtex, fiber length: 52 mm) of PPTA fiber (trade name: "Kevlar" (registered trademark)) manufactured by Toray DuPont Co., Ltd. were produced.

[0048] [Production Example 4 (Bulk yarn)] Using a filament yarn of PPTA fiber (manufactured by Toray DuPont Co., Ltd., trade name: "Kevlar" (registered trademark)) with a single fiber fineness of 1.67 dtex and a total fineness of 444 dtex, continuous false twisting was performed to obtain crimped yarns (S twist, Z twist) of PPTA fiber with an elastic elongation rate of 22%.

[0049] (Examples 1, 3, 5 to 7; 7G, no supplementary yarn) When supplying two to four fluid-processed yarns obtained in Production Examples 1 and 2 to a 7-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.), seamless gloves were knitted in the conventional manner, except that among the yarn guides, washers with a matte surface were used for two of the washer tensioners. That is, the yarn path part of the tension shaft of the washer tensioner was made of an alumina ceramic guide (YM99C manufactured by Yuasa Yarn Path Co., Ltd., density: 3.8, hardness: 1800, Rmax: 1.5 μm), the upper and lower two tension washers were made of matte chromium plating, and the other yarn guides were used in a mixture of alumina ceramic, matte chromium plating, and non-plated guides without changing from the knitting machine specifications.

[0050] (Examples 2, 4; 7G, with supplementary yarn) Three fluid-processed yarns (ground yarns) obtained in Production Example 1 and one stretchable supplementary yarn (woolly-processed yarn made of 155 dtex nylon fiber, twist direction: Z twist) were supplied to a 7-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.), and gloves were knitted by plating knitting with the ground yarns arranged on the outer surface and the supplementary yarn on the inner surface.

[0051] The gloves obtained in Examples 1 to 7 were excellent in low dust generation and cut resistance, and had a soft and voluminous texture.

[0052] (Comparative Example 1; 7G) A seamless glove was knitted in the same manner as in Example 1, except that 5 spun yarns obtained in Production Example 3 were used. The resulting glove was excellent in cut resistance, but had a large amount of dust generation and a prickly feeling.

[0053] (Comparative Example 2; 7G) A seamless glove was knitted in the same manner as in Example 1, except that 6 bulky textured yarns (3 S-twisted and 3 Z-twisted) obtained in Production Example 4 were used. The resulting glove was excellent in cut resistance, and the amount of dust generation was reduced compared to the spun yarn, but it was about 2 to 3 times the amount of dust generation of the fluid textured yarn.

[0054] (Example 8; 10G, with filling yarn) One fluid textured yarn (ground yarn) obtained in Production Example 1 and one stretch filling yarn (woolly textured yarn made of 155 dtex nylon fiber, twisting direction: Z-twist) were supplied to a 10-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.), and a glove with the ground yarn arranged on the outer surface and the filling yarn on the inner surface was knitted by plating knitting.

[0055] (Example 9; 10G, without filling yarn) A seamless glove was knitted in the same manner as in Example 1, except that two fluid textured yarns obtained in Production Example 2 were supplied to a 10-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.).

[0056] The gloves obtained in Examples 8 to 9 were excellent in low dust generation and cut resistance, and had a soft and voluminous texture.

[0057] (Comparative Example 3; 10G) A seamless glove was knitted in the same manner as in Example 9, except that two spun yarns obtained in Production Example 3 were used. The resulting glove was excellent in cut resistance, but had a large amount of dust generation and a prickly feeling.

[0058] (Comparative Example 4; 10G, without filling yarn) A seamless glove was knitted in the same manner as in Example 1, except that one fluid-processed yarn obtained in Production Example 1 was supplied to a 10-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.). The resulting glove was a bare glove with a poor fit.

[0059] (Examples 10 to 11, 13; 13G, no additional yarn) A seamless glove was knitted in the same manner as in Example 1, except that one or two fluid-processed yarns obtained in Production Example 1 were supplied to a 13-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.). However, Example 10 is a reference example.

[0060] (Examples 12, 14; 13G, with additional yarn) One fluid-processed yarn (ground yarn) obtained in Production Example 1 and one stretchable additional yarn (a wool-processed yarn made of 78 dtex nylon fiber (twist direction: Z twist)) were supplied to a 13-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.), and a glove was knitted by plating knitting with the ground yarn on the outer surface and the additional yarn on the inner surface.

[0061] The gloves obtained in Examples 10 to 14 were excellent in low dust generation and cut resistance, had a soft and voluminous texture, and among them, the gloves of Examples 12 and 14 using stretchable additional yarns had a good fit.

[0062] (Comparative Example 5; 13G) A seamless glove was knitted in the same manner as in Example 10, except that two bulky-processed yarns obtained in Production Example 4 (one S twist and one Z twist) were used. The resulting glove was excellent in cut resistance but had a large number of dust emissions.

[0063] (Examples 15 to 16, 18, 20; 15G, with additional yarn) One fluid-processed yarn (ground yarn) obtained in Production Examples 1 and 2 and one stretchable additional yarn (a wool-processed yarn made of 78 dtex nylon fiber (twist direction: Z twist)) were supplied to a 15-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.), and a glove was knitted by plating knitting with the ground yarn on the outer surface and the additional yarn on the inner surface.However, Examples 15 to 16 are reference examples.

[0064] (Examples 17, 19; 15G, without added yarn) A seamless glove was knitted in the same manner as in Example 1, except that one fluid-processed yarn obtained in Production Example 2 was supplied to a 15-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.).

[0065] The gloves obtained in Examples 15 to 20 were excellent in low dust generation and cut resistance, and had a soft and voluminous texture. Among them, the gloves of Examples 18 and 20 using a ground yarn with a fineness of 670 dtex and an elastic added yarn had a good wearing feeling.

[0066] (Comparative Example 6; 15G) A seamless glove was tried to be knitted in the same manner as in Example 17, except that one bulky-processed yarn obtained in Production Example 4 was used. However, the yarn was twisted and could not be knitted.

[0067] (Comparative Examples 7 to 8; 15G) A seamless glove was knitted in the same manner as in Example 17, except that one fluid-processed yarn obtained in Production Example 1 was supplied to a 15-gauge type glove knitting machine (manufactured by Shima Seiki Mfg., Ltd.). The obtained glove was a bare glove with a poor wearing feeling.

[0068] The glove configurations and evaluation results are summarized in Table 1.

[0069]

Table 1

[0070] From Table 1, it can be seen that by knitting gloves using organic fiber yarns with a fineness of 440 to 1,800 dtex that have been fluid injection processed at an overfeed rate of 3 to 10%, cut resistance gloves can be obtained with a cut resistance of 5 N or more and a dust generation count of 100,000 or less per two gloves for particles with a particle size of 0.1 μm or more. Also, by knitting gloves using ground yarns made of the above organic fiber yarns and elastic added yarns, it can be seen that cut resistance gloves can be obtained with a cut resistance of 5 N or more and a dust generation count of 100,000 or less per two gloves for particles with a particle size of 0.1 μm or more.

[0071] In the case of thick gloves knitted with 7G and 10G, conventional spun yarns and bulky processed yarns cannot provide gloves that satisfy both cut resistance and low dust generation, whereas the fluid processed yarns of the present invention can provide gloves that satisfy both cut resistance and low dust generation. Also, in the case of thin gloves knitted with 13G and 15G, conventional bulky processed yarns could not be used singly, whereas the fluid processed yarns of the present invention can provide gloves that satisfy both cut resistance and low dust generation even when used singly.

Industrial Applicability

[0072] The cut resistance gloves of the present invention and the method for manufacturing the same are useful as work gloves that dislike dust contamination and the like. The cut resistance gloves of the present invention are useful as gloves for various operations performed in a clean room to meet the standards of clean room clothing, as work gloves in fishing, agriculture, the food industry, medicine, the high-tech industry, etc., or as sports gloves.
