Abstract

Compared with conventional knitting gloves using a fully automatic glove knitting machine and gloves sewing a thin fabric, a warp knitting machine is used to obtain a non-slip knitted glove having excellent workability. The anti-slip knitted glove of the present invention uses a warp knitting machine to form a front and back base fabric in a finger bag portion, a main body portion and a cuff portion in a cylindrical shape, and each side edge portion and a tip portion of each finger bag portion. An anti-slip knitted glove in which an elastomer or a resin film is formed on the entire surface layer or a part of the surface layer of the glove.

Description

  TECHNICAL FIELD The present invention relates to a knitted glove with a non-slip that greatly improves workability and a method of manufacturing the same for a knitted work glove used for assembling various parts.

  Knitted gloves used for work gloves are knitted using a flat knitting machine (a fully automatic glove knitting machine) for gloves. The width of the thickness of the thread used for the knitted gloves of this work glove is widely disclosed. (For example, refer to Patent Document 1). Work gloves made of anti-slip processing on knitted gloves knitted by a fully automatic glove knitting machine are used for many tasks such as assembly work. Knitted gloves knitted with 13 gauge and 15 gauge yarns, which are relatively high gauges of flat knitting machines, are thick, and when coated with non-slip, such as polyurethane, the thickness exceeded 1.0 mm and was completed. The non-slip work gloves were hard and had poor workability and fit.

  The proper total number of deniers for yarns used in 13-gauge and 15-gauge flat knitting machines, which are often used in work gloves for assembly work, etc. is about 319 denier, and the actual used range is about 280-320 denier. Met. The thickness of the yarn has an optimum range depending on the gauge number of the knitting machine, and the number of usable yarn denier is determined by the gauge number of the flat knitting machine. There is a problem that it is difficult to use for the above-described flat knitting machine.

  For this reason, attempts have been made to manufacture knitted gloves with a flat knitting machine using yarns having a smaller denier number than conventional yarns in order to reduce the thickness of the knitted gloves (see Patent Documents 2, 3 and 4). ).

  Illustratively, according to the method of knitting using an 18 gauge flat knitting machine, a thin knitted glove can be knitted by knitting with a yarn of 221 denier or less, and a glove with good workability and fit is obtained ( Patent Document 3). Since the appropriate denier number of the yarn of an 18 gauge flat knitting machine is smaller than 13 gauge and 15 gauge, it was suitable for production. However, it has not been possible to knitting gloves using thin yarns of less than 100 denier with a fully automatic glove knitting machine. For example, referring to Knitting Technology (Non-Patent Document 1), the appropriate total denier of yarns used in flat knitting machines is determined by the number of gauges, and in general, it can actually be used at 13 gauges and 15 gauges. Such a range is about 280 to 320 denier.

  Gloves are knitted with yarns composed of water-soluble fibers and water-insoluble fibers, and as a post-treatment after knitting, a glove composed of yarns of water-insoluble fibers from which water-soluble fibers are removed by applying to water is obtained (Patent Document) 2). According to Patent Document 2, it takes time for water washing, and when washing is insufficient, water-soluble fibers become impurities. Moreover, since the size of the stitches is not different from that when knitting the composite yarn, there is a problem that the stitches are coarse.

  A method of coating a non-porous moisture-permeable and waterproof polyurethane resin layer on a wet polyurethane film formed by placing a hand knitted using a sewing fiber fabric on a hand mold and then forming a wet polyurethane film thereon is described. (Patent Document 4). According to this method, a thin fiber cloth having a thickness of 500 μm or less and a longitudinal tensile elongation of 170% or more is used as a sewing glove, so that it does not easily break even if the glove is thin. Due to the inherent softness of thin sewing fabrics, the coating layer does not easily peel or break even with excessive tension or external force, fits in the hand, has good workability, moisture permeability and waterproofness, work on touch panels, etc. A glove that can be used.

  In Patent Document 3, a glove using a thin thread of less than 100 denier could not be knitted. Therefore, it has been difficult to obtain a glove with further improved workability with this knitted glove. According to Patent Document 4, a glove having a thin fiber fabric and a fine stitch can be manufactured as compared with a glove produced by a conventional flat knitting machine (fully automatic glove knitting machine). In order to manufacture gloves using technology, there is necessarily a seam allowance by sewing on both sides of each finger. In the glove using the above-described sewing fiber fabric, the sewing allowance of the sewing portion is around the hand and the tip of the finger. Therefore, when performing a fine work with the fingertip, the workability is reduced due to the existence of the sewing allowance.

  For this reason, the seam allowance comes into contact with the hand inside the glove and the feeling of wearing and fitting is impaired, and there is a problem from the viewpoint of workability. In the case of a sewing glove, processes such as production of fabric, production of a fabric (cutting of a mold), sewing, and the like are performed, so that the production cost and the unit price of the product increase from the viewpoint of labor costs and the number of processes.

  On the other hand, in the case of a fully automatic glove knitting machine which is a flat knitting machine, although it is a production method capable of processing directly from a yarn raw material to a state close to the final product, the use of a high gauge number has a limit in the structure of the knitting machine. By using thin denier yarn with a high gauge number flat knitting machine, the thickness is thinner, softer, fits hands and has better workability than gloves knitted with conventional flat knitting machines. Therefore, it was difficult to obtain gloves suitable for more precise and detailed work.

Knitting Technology (by David J. Spencer)

  In the previous patent application (Japanese Patent Application No. 2014-052572), the present inventors have widely used 13 gage and 15 gage which are equivalent to thin work gloves that can be manufactured with an 18 gage knitting machine. A working urethane-coated glove that can be manufactured at low cost by using a yarn of 100 denier to 200 denier with a flat knitting machine and a method for manufacturing the same are disclosed.

However, even with this method, it is not possible to produce knitted gloves using yarns of less than 100 denier, and the knitted gloves with anti-slip are thinner and better in workability than the method using a conventional flat knitting machine (fully automatic glove knitting machine). Could not get.
In the knitting method of gloves using a warp knitting machine (see Utility Model Registration No. 3118655), when the needle bed rises during knitting, the knitting needle removes the stitches below the spatula and simultaneously introduces the yarn into the stitches. Is called. When the needle bed descends, the knitting needle knocks over, the new stitch is pulled down through the old stitch, and the front course fabric and the rear base are fed by feeding the stitch of the previous course to the back of the needle by casting off. A tubular knitted fabric is formed by knitting the fabrics at the same time and knitting the side edges of the respective base fabrics. Although it is knitted and closed at the side edge of each base fabric by a well-known jacquard mechanism, according to a normal knitting method, the tip of the tubular portion of each finger pouch portion is an open end cut in the same manner as the cuff portion. .

  However, even when using thin gloves with good workability obtained by the method using conventional flat knitting machines and warp knitting machines, anti-slip gloves are controlled to impregnate knitted gloves with elastomer or resin as a coating material. As a result, the formation of the coating layer becomes uneven, and as a result, the non-slip gloves are not sufficiently flexible, and it is very difficult to handle very small parts, specifically, parts having a diameter of about 2 mm. It was. An object of the present invention is to obtain a non-slip knitted glove capable of such ultra-precision work.

As a result of intensive studies, the inventor has used a knitted glove created by a warp knitting machine (more specifically, a double raschel knitting machine having a jacquard mechanism) as a master hand, thereby knitting gloves by a conventional fully automatic glove knitting machine, Compared to gloves made by sewing thin fabrics, it is possible to obtain anti-slip gloves that are superior in workability, and it has been found that it is very close to a bare-handed sensation that is unprecedented in fine work using fingertips. It came.
The present invention uses a warp knitting machine to form the front and back base fabrics in a cylindrical shape at the finger bag portion, the main body portion and the sleeve portion, and closes the side edge portions of these portions and the tip portions of the finger bag portions. This is a knitted glove with a non-slip formed by forming a non-slip elastomer or resin uniformly impregnated film on the entire surface layer or a part of the surface layer of the knitted glove. The film of elastomer or resin may be a film layer containing foam (bubbles).
This anti-slip knitted glove has made it possible to perform ultra-precise work that was very difficult with conventional anti-slip knitted gloves.

  The knitting of the knitted gloves using the warp knitting machine of the present invention does not require post-processing such as overlock, and the production process can be shortened and labor saving compared to the case of being produced by a fully automatic glove knitting machine. This is a glove that holds a thinner fiber fabric than conventional products by using a method that manufactures the original hand of knitted gloves and processes directly from the yarn raw material into a form close to the final product. It is possible to omit unnecessary production processes.

  A knitted glove with a non-slip coating film is knitted using a thin thread on a warp knitting machine with a large gauge number, and is uniformly formed as a film covering the fiber on the surface of the glove. By utilizing the characteristics of the knitted gloves, a working knitted glove having improved flexibility and workability of the gloves can be obtained.

  The anti-slip knitted glove of the present invention is a knitted glove obtained by applying anti-slip to a knitted glove knitted by a warp knitting machine, and an anti-slip elastomer or resin is adhered to all or a part of the surface of the glove. A non-slip knitted glove having a coating layer formed thereon.

  In the knitted gloves, the thickness of the yarn used in the warp knitting machine is 10 to 420 denier, preferably 10 to 100 denier, more preferably 20 to 50 denier.

In the knitted gloves, the warp knitting machine has a gauge number of 20 to 32 gauge, preferably 24 to 32 gauge, more preferably 28 to 30 gauge.
The knitting gloves may be knitted by a warp knitting machine, preferably double raschel knitting.

  In the above knitted gloves, the type of yarn used in the warp knitting machine is preferably nylon, polyester, spandex, aramid, polyethylene, cotton, or a combination thereof. In the knitted glove, the elastomer or resin may be natural rubber, NBR, butadiene rubber, chloroprene rubber, silicone rubber, polyurethane, PVC, or a combination thereof.

  The above knitted gloves have a thickness including an anti-slip of 1.0 mm or less, preferably 0.7 mm or less.

  The glove manufacturing method according to the present invention uses a warp knitting machine in which each knitting needle is fed independently through each pair of yarn guides and each knitting needle, and the front and back of each finger bag portion, main body portion and sleeve portion. The base fabric is formed into a cylindrical shape, and the process of knitting the knitted glove by knitting and closing each side edge and the tip of each finger bag part, anti-slip on the entire surface or only part of the knitted glove It is a manufacturing method of the knitted glove with a non-slip | sticker including the process of making an elastomer or resin adhere, and forming a coating layer.

  The above-described method for manufacturing a knitted glove is a double raschel knitting machine in which a warp knitting machine has a jacquard control mechanism.

  In the manufacturing method of the knitted gloves, the number of gauges of the warp knitting machine is 20 to 32 gauges, preferably 24 to 32 gauges, more preferably 28 to 30 gauges.

  In the method for producing the knitted glove, the thickness of the yarn used is 10 to 420 denier, preferably 10 to 100 denier, more preferably 20 to 50 denier.

  In the knitted glove manufacturing method, the elastomer or resin may be natural rubber, NBR, butadiene rubber, chloroprene rubber, silicone rubber, polyurethane, PVC, or a combination thereof.

  As a result of intensive studies, the inventor used a knitted glove created by a warp knitting machine as a raw hand and coated an elastomer or a resin non-slip on the entire surface or a part of the surface of the glove. Compared to knitting gloves made with a glove knitting machine and gloves made from thin fabric, anti-slip gloves with excellent workability can be obtained. An effect that is close to is found. Compared to the conventional glove, the knitted glove created by a double raschel knitting machine with a jacquard control mechanism is used as a hand and the entire surface or only part of the glove is coated with elastomer or resin anti-slip. Work that handles extremely small parts has become possible.

The non-slip knitted glove formed by attaching the non-slip elastomer or the resin 41 to the seamless knitted glove.

[Warp knitted gloves]

A knitted glove 30 knitted using a warp knitting machine is used for the working knitted glove of the present invention. A double raschel knitting machine having a jacquard control mechanism of a warp knitting machine currently on the market, as a representative example, manufactured by KARL MAYER AG (Germany), model: RDPJ6 / 2, HDRPJ10 / 2, etc. can be used. For example, referring to JP 2010-196184 A, a double raschel (double raschel machine) is a double needle row warp knitting machine having a front needle row and a rear needle row. The front knitting part is knitted by the front needle row, the rear knitting part is knitted by the rear needle row, the front part of the tubular knitting and the rear part of the tubular knitting are knitted, and an opening edge at the end in the tubular direction. Knitting a tubular knitted product. In knitting, with the knitted fabric of the front and rear parts knitted simultaneously on a double raschel warp knitting machine, the opening edge is positioned linearly in the knitting direction at the end in the knitting width direction of each region corresponding to each tubular knitted product The knitting width direction is set to the knitting width direction so that knitting is repeated continuously in the knitting direction. Usually, a plurality of tubular knitted products are arranged in parallel in the knitting width direction and continuously knitted in the knitting direction. In this knitting, a reinforcing yarn or an elastic yarn is knitted over a required width in the opening edge portion, and a yarn that adds functionality such as an elastic yarn is knitted in the belt-like region. As an example of an existing double raschel knitting machine having a jacquard control mechanism, the gauge number of a warp knitting machine is generally 20 to 32 gauge. In order to obtain a thin knitted fabric, the gauge number of the warp knitting machine is preferably 24 to 32 gauge. On the other hand, in a fully automatic glove knitting machine, there is currently no model that conventionally exceeds 18 gauges. The jacquard control mechanism is a control mechanism that controls the arrangement of guide needles that form the jacquard ridge when the knitted fabric is knitted with the basin and the jacquard heel, and each heel is over the front needle row and the rear needle row. It is also possible to wrap. According to a normal knitting method, an open end portion that is cut in the same manner as the cuff portion is formed, but in the case of gloves, in the lateral direction at the side edge of the base fabric knitted on the knitted fabric of each finger bag portion The knitting control mechanism is a knitting control mechanism that is knitted and closed by a chain stitch or the like to be connected, and the open end of the cylindrical portion can be separated as an edge that does not require terminal processing.

  In the warp knitting machine, the knitting needles arranged on the needle bed move up and down during knitting, and the wrapping movement of the ground is performed together with the clearing operation of the knitting needles, so that one course is knitted simultaneously to form a knitted fabric. The base fabric on the front side and the base fabric on the rear side are fed simultaneously to the knitting needles of all knitting widths through a pair of yarn guides to form a cylindrical portion, and after knitting, along the glove-shaped outer edge It is commercialized by cutting the knitted closed part.

The machine conditions of the knitting machine are fed using a 28-gauge double raschel knitting machine, instead of the conventional fully automatic glove knitting machine using flat knitting, and a double raschel knitting machine with higher gauge models. Knitted gloves are knitted using nylon yarn of about 20 denier. A specific knitting method is as follows.
For example, in the case of a warp knitting machine, the yarn material used as the raw material yarn can be both a ground yarn and a jacquard yarn feeding method. In a preferred embodiment, the warp knitting machine has a gauge number of 28 gauges, and the yarn is knitted on both the ground and jacquard ridges. The yarn count is 15 to 40 denier, more preferably 20 to 32 denier. As the yarn material, for example, a raw yarn that is any one of nylon, polyester, spandex, aramid, polyethylene, acrylic, cotton, or a combination thereof can be used. In addition, the use of stretchable (crimpable) wooly nylon, polyester, etc. makes it tightly attached to the hand mold to be covered when coating knitted gloves, and is also useful when immersed for film formation. There is obtained a knitted glove in which a coating film having a uniform thickness is formed in a desired range without any displacement from the mold.

[Cleat]
An anti-slip coating film is formed on the surface of the knitted glove by immersing, drying and curing a hand mold with a knitted glove covered with an emulsion-based elastomer dispersion such as NBR, natural rubber, butadiene rubber, and water-based polyurethane. In addition to the emulsion dispersion system of these elastomers, the anti-slip coating film can be formed by dissolving the elastomer in a solvent and performing wet film formation and dry film formation using, for example, solvent-based polyurethane.

[Knitting of warp knitted gloves]
As one mode of knitting of warp knitted gloves, as shown in FIG. 2, the front base fabric 9 and the rear base fabric 10 are knitted by connecting knitting that connects both the left and right side portions, thereby forming a cylindrical knitted fabric. Can be obtained. For example, as shown in FIG. 1B, according to the double raschel knitting, a plurality of pairs of left and right gloves are formed in series in the longitudinal direction. Another pair of left and right gloves may be formed in parallel. Usually, the width in the course direction of the warp knitting machine is larger than the width of the product glove, and production is performed using a continuous knitting method in which two or more rows are arranged in parallel. It is preferable because of improved properties.

[Anti-slip processing]
Conventionally, there are a coagulation method and a heat-sensitive method as a method of forming a rubber coating layer such as NR and NBR as a non-slip material on a glove. The anti-slip material is not particularly limited, but it is dispersed in plasticizers such as natural rubber, NBR, butadiene rubber, emulsion type such as water-based polyurethane, and solvent-based polyurethane coated by wet or dry film formation. PVC that is post-coated and heat-cured can be used (see JP 2013-167042 A). Moreover, the above-mentioned anti-slip | skid can also be made to foam arbitrarily.

  Although the range which performs a non-slip process is not specifically limited, What formed the coating layer in partial surfaces, such as the whole surface of a glove, or a fingertip, is desirable.

  When the anti-slip process is applied only to the fingertip part, the anti-slip process is not applied to any part other than the fingertip, so that the flexibility of the knitting is utilized and a glove with very good workability is obtained.

  When the palm part is subjected to anti-slip processing, it is difficult to slip during work, and the back of the hand is not anti-slip processing, so that a glove that is highly breathable and difficult to squeeze is obtained.

  When anti-slip processing is applied to the entire surface of the glove, dirt such as oil or dirt or mud does not enter the glove due to the characteristics of the coating coating layer, so that a glove can be obtained in which hands are not soiled.

[Knitting method of warp knitting gloves]
Specific knitting conditions by the warp knitting machine of the present invention are as follows.
Gloves are knitted together in the warp knitting direction, and then separated into single gloves to form a pair of gloves. A glove which is an example of a tubular knitting by warp knitting is composed of a knitted tissue of a glove including an open edge.

  Referring to FIG. 1A showing an example of knitting of a tubular knitted fabric of a double raschel knitting machine having a jacquard control mechanism (Japanese Patent Laid-Open No. 2007-77544), a tubular sock was formed and discharged from a warp knitting machine. When the continuum is viewed from the front side, the knitting direction is the vertical direction. That is, the knitting direction is the vertical direction discharged from the warp knitting machine, and the course direction orthogonal to the vertical direction is abbreviated as a horizontal direction or a left-right direction. As an example in which the knitting method of the tubular knitted fabric shown in FIG. 1B is applied to a knitted glove, the front base fabric 9 and the rear base fabric 10 are formed in a cylindrical portion, and the side edges of each base fabric are controlled by jacquard control. 11 is closed. The cylindrical part of the finger bag part 1 of the glove 30 is formed by a longitudinal knitted fabric that is fed independently. After knitting, the knitted and closed part is cut along the outer edge of the glove shape. The side portion 7 of each finger bag 1 is formed into a tubular shape by connecting knitting that connects the side surfaces of the lower finger bag portion 1b of the rear base fabric 10 corresponding to the side surface of the upper finger bag portion 1a of the front base fabric 9. On the other hand, the front end portion 8 of each finger bag 1 is connected to the front side of the front end portion of the upper side finger bag portion 1a of the front base fabric 9, the rear side of the front end portion of the lower finger bag portion 1b of the rear base fabric 10, and the left and right sides of the front end portion. The ends are connected by side (lateral) connecting knitting, and the fingertips are closed. In the case of the working knitted glove 30, the knitting operation of the warp knitting machine for knitting into a knitted glove that forms a tubular knitted fabric in which each finger of the glove, palm, and wrist is connected to the front and back is set. (For example, stored as a dedicated knitting program).

  The open edge 31 of the conventional knitted glove 30 knitted with a single knitted fabric shown in FIG. 2 is cut at a portion separated from the base fabric of the knitted structure shown in FIG. The front base fabric 9 and the rear base fabric 10 are warp knitted fabrics that can form a knitted fabric in which the left and right sides are joined in the longitudinal direction. Although it is easily knitted with a denbi structure, it is not limited to this, and other warp knitted structures may be used, for example, a half structure, a mesh structure, an atlas structure, etc., and a knitted pattern may be given. An appropriate knitted structure can be adopted depending on the application, such as improving air permeability by opening the mesh. In the case of a warp knitting machine, for example, since the jacquard folds are separately controlled by computer control, the back side and the palm side of the hand of the knitting glove 30 constituting the work gloves can be knitted into different knitting structures. The degree of stitches can be changed by individually changing the amount of yarn supplied to the ground and jacquard. Therefore, for example, it is possible to adjust the finish and texture of the glove along the shape of the hand mold described later.

  The front base fabric 9 and the rear base fabric 10 are knitted into a cylindrical shape, and then the rear side of the front base fabric 9 with respect to the side surface of the upper finger bag portion 1a in the finger bag side portion that divides each finger bag portion 1 separately. In order to connect the side surfaces of the lower finger pouch portion 1b of the side base fabric 10, the front side of the barrel knitted in the cylindrical shape shown in FIG. 4 and the side portions 11 of the rear base fabrics 9 and 10 are connected. In the same manner as in the above, a tubular bag is formed by connecting and knitting with connected knitting. For example, when knitting the left side portion 11a of each of the left and right side surfaces of the finger bag portion 1 and when knitting the right side portion 11b of each side surface, each finger bag is formed into a cylindrical shape by knitting with a symmetrical knitting structure. .

  The thickness of the yarn that can be used in the 20-32 gauge double raschel knitting machine used in the knitted glove of the present invention is preferably in the range of 10 denier (11 dtex) to 210 denier (231 dtex) as an inelastic yarn ( Natural fiber yarn is a count converted to this thickness), and elastic yarn is usually 10 denier (11 dtex) to 420 denier (462 dtex), preferably 10 denier to less than 100 denier, more preferably 20 to 50 denier. Arbitrarily selected. For example, in the case of 28 gauge, the yarn material is preferably a stretched woolly (crimped) nylon fiber or a wooly polyester fiber as both yarn and jacquard yarn, and the count is 15 to 40 denier. And 20 to 30 denier as the optimum count.

  As shown in FIG. 1B, the knitting structure of the portion in which the plurality of gloves are connected in series is not limited as long as the plurality of gloves can be connected in the vertical direction. For example, the same knitting structure as that of the main part of the front base fabric 9 and the rear base fabric 10 or a different knitting structure may be used. When the non-elastic yarn of the glove body base fabric is formed of a denbi structure, the knitted fabric of the front sleeve opening 6a and the knitted fabric of the rear sleeve opening 6b are respectively the right side as the knitted structure of the elastic yarn. The knitted fabric is a knitted fabric in which the stitches are swayed by one stitch in the wale direction (see FIG. 5). By the knitting in which the elastic yarn is knitted, the expansion / contraction force of the sleeve opening or the like is changed as compared with the expansion / contraction force by the non-elastic yarn of the glove body base fabric.

  It is not limited only to the knitting structure in which all the stitches are shaken by one stitch in the right wale direction, and the stretching force of the knitting structure of the glove can be adjusted. For example, instead of all the right side stitches, every other knitting structure that is swayed by one stitch in the right waling direction, two right knitting parts are each swayed by one stitch in the right waling direction, One of the stitches may have a repetitive knitting structure that does not swing in the right wale direction. Therefore, if all the other conditions (for example, the type and thickness of the elastic yarn to be used) are the same when comparing the expansion / contraction force of the sleeve opening 6, the sleeve opening 6 has a ratio of the portion to be swung by one stitch. The stretching force can be adjusted as desired. In the case of a warp knitting machine, the degree of stitches can be changed by individually changing the yarn feed amount to the ground and jacquard folds. Therefore, for example, it is possible to adjust the finish and texture of the glove along the shape of the hand mold described later.

  The boundary line between the tip of the finger bag and the tip of the sleeve opening is usually difficult to discern, so specify which part of the knitted continuum is cut to obtain or cut each glove. It ’s difficult. Therefore, it is also possible to knit by changing the knitting structure so that at least a part of the outer edge region of the tip of the finger bag and the tip of the sleeve opening can be visually distinguished from the tip of the finger bag and the tip of the sleeve opening. .

[Anti-slip processing method]
When using a solvent-based polyurethane resin as an anti-slip elastomer, a method for forming a coating layer on a knitted glove is to place the glove on a hand mold and use a polyurethane resin solution dissolved in a hydrophilic solvent such as dimethylformamide or dimethyl sulfoxide. Soak slowly, impregnate the glove with the resin solution, attach it, pull up the hand mold, remove the excess resin solution, replace the hydrophilic solvent remaining in the glove with water or warm water and replace the polyurethane resin There is a method of gelling. The drying temperature is preferably a temperature at which the polyurethane resin does not melt if the temperature is too high.

  As the viscosity of the resin solution increases, the amount of resin attached to the glove increases. In this case, since it becomes a hard knitted glove with non-slip, flexibility is lost and workability is also lacking. When the amount of resin adhering to the glove decreases, the coating layer has many voids. In the case of a polyurethane resin, the viscosity of the resin solution is preferably 10 to 5000 cps, and the resin concentration is preferably 2 to 20% by weight.

  In the natural rubber (NR) heat-sensitive method, a fiber glove is put on a hand mold and heated to a certain temperature, and a glove coating layer is formed on a natural rubber latex emulsion containing a heat-sensitive coagulant such as polymethyl vinyl ether. A knitted glove having a natural rubber (NR) coating layer cured by dipping, drying, releasing, leaching and heat treatment is obtained. In the coagulation method such as NBR, a knitted glove is put on a hand mold and heated to a certain temperature, soaked in a coagulant such as a calcium nitrate methanol solution, and a glove coating layer forming part is soaked in a rubber latex emulsion. dry. Thereafter, release, leaching and heat treatment are performed to obtain a glove having a cured NBR coating layer. Even with a coagulation method using natural rubber (NR), a glove having an NR coating layer cured by the same process as the NBR coagulation method can be obtained.

In the aspect described above,
(1) The open edges of the front cuff part and the rear cuff part are formed of a knitted structure having a larger knitting in the wale direction than the knitted structure of the glove body base fabric. Using elastic yarn, the elastic force of the sleeve opening is larger than the elastic force of the glove body base fabric, and demonstrates the function of preventing slippage. In this way, swinging by one stitch in the wale direction and changing to the various knitting structures described above can be easily realized by using a double raschel knitting machine having a jacquard mechanism. Even if it is in a cut or cut state and is not subjected to special terminal processing, the cut edge is not unraveled.

(2) The immersion part of the glove is not particularly limited, and a coating layer such as polyurethane resin is formed at an arbitrary part. That is, the covering layer only needs to be formed on at least a desired part of the hand, for example, the entire outer surface of the hand, only the fingertip part, or only on the palm part of the hand so as to be in a spine-out state. A coating layer can be formed on the substrate.

(Connected knitting)
On the sides of the front and back base fabrics, the front and back base fabrics are connected by connecting knitting that connects both the left and right sides, and connected to a tubular knitted fabric. The knitting structure of the connected knitting is a knitting method that is passed through the same wales on the front and back sides and does not swing in the left-right direction, and the front base fabric has an upper finger bag part, a back part (upper trunk part), and an upper cuff part. The rear base fabric forms a lower finger bag part, a palm part (lower trunk part), and a lower cuff part. When knitting the front end of the finger bag so that the front side and the rear side are closed, the front base fabric and the rear base fabric are connected to the front side, the rear side, and the left and right sides (lateral direction) by connecting knitting to form the front end portion of the finger bag. . The yarns are fed in order from the bottom to the front on the right side, the rear side on the left side, then the front side, then the front side on the right side, and further to the rear side on the left side. It becomes a knitting organization of connected knitting. Accordingly, the tip of the finger bag can be closed to form a bag.
Usually, the knitting structure of the connected knitting goes through the same wales, in other words, a knitting method that does not shake in the left-right direction, and the seam is not visually recognized.

(Wet deposition)
In order to adjust the thickness of the coating layer formed in order to form a flexible wet coating layer, it is necessary to control the process of substituting the hydrophilic solvent component in the polyurethane resin solution in water. When the progress of water replacement becomes faster, the coating layer has more holes on the glove surface side, and the thickness of the coating layer becomes thinner and the strength becomes weaker. On the other hand, when the progress of water replacement is slow, it is difficult to form holes, the thickness of the coating layer increases, and the glove feel tends to be hard.

  The addition amount of the surfactant is appropriately determined according to the polyurethane resin to be used. If a hydrophilic surfactant is blended, the water replacement rate of the solvent tends to increase. Conversely, if a hydrophobic surfactant is blended, the substitution rate tends to be slow. The addition amount of the surfactant is appropriately determined according to the polyurethane resin to be used.

  A specific method for controlling the wet coating layer is as follows. By replacing the hydrophilic solvent of the polyurethane resin impregnated in the glove, which is a fiber base material, with water, the solvated polyurethane resin gels, and the glove And the polyurethane resin are in close contact with each other. The time required for replacement is the time for extracting and replacing the hydrophilic solvent in the polyurethane resin solution. When the hydrophilic solvent remains in the polyurethane resin, the polyurethane resin is dissolved again, so that the obtained coating layer tends to be nonporous.

(Manufacturing method of warp knitted gloves)
In order to form a pair of left and right gloves in parallel in the horizontal direction, the portion that becomes the boundary of the main body portion is knitted by connecting the front base fabric and the rear base fabric by connecting knitting as described above. Since the knitted structure does not swing in the left-right direction, the adjacent regions on the sides of the left and right gloves are formed apart from each other (not connected). It seems that the left and right gloves are completely separated from each other in the longitudinal direction and discharged individually from the warp knitting machine. If the part of the knitting structure is a knitting structure in which the connection is also generated in the left-right direction, the connection of the part is maintained and discharged from the knitting machine as a continuous body. And it cut | disconnects along the outer edge of the finger-bag front-end | tip of the one end part of a glove or the other end cuff opening edge of a glove, and obtains each glove. If a portion formed longer than the longitudinal length of the finger bag tip is provided, the finger bag portion is not cut in a connected state when cut. If the side part which becomes the boundary between the left and right body parts is also provided with a part formed longer than the upper edge of the cuff opening, the left and right gloves will not be cut at the upper end when cut.

  For example, when the cuff part of a glove is knitted, when the cuff part open edge is reached, the knitted structure is changed and knitted. If a double raschel knitting machine having a jacquard mechanism is used, it is possible to partially change the knitting structure of one yarn in the longitudinal direction. A control unit that inputs a command of a knitting structure of a double raschel knitting machine having a jacquard mechanism is to start with a continuous knitting structure with respect to the yarn at a specific position, and at the position that reaches the open edge of the cuff part, It is only necessary to input a command to make the knitted structure into a continuous knitted structure again and knit it.

  In addition, a sleeve opening is formed at the end opposite to the tip of the finger bag. When forming the sleeve opening, the elastic yarn knitted in the sleeve opening is preferably a glove body base. It is formed of a knitting structure in which the swing in the wale direction is larger than the knitting structure of the yarn of the fabric. When elastic fibers are used on the outer surface side of the glove, if the elastic fibers are vulnerable to heat and tend to deteriorate, the elastic fiber core yarn covered with nylon, polyester fiber, etc. is used for the purpose of preventing the elastic fibers from being exposed. It is preferable to use it. Thereby, an elastic fiber can hold | maintain an elastic force even after the heat processing in the case of the process which gives a slip stopper.

(Wet processing)
According to the wet processing method described above, when a polyurethane resin coating layer is formed, a hand mold with a hand attached is immersed in a polyurethane resin solution, and the temperature of the hand mold at this time is about room temperature to about 100 ° C. Preferably there is. Considering actual production, it is not realistic because a cooling facility is required to lower the temperature of the hand mold to lower than room temperature. When the temperature of the hand mold exceeds 100 ° C., the viscosity of the attached polyurethane resin solution is lowered and the fluidity is increased, so that the adhesion is uneven and the resulting coating layer is also uneven. . More preferably, it is normal temperature-70 degreeC.

  In the step of substituting the hydrophilic solvent in the polyurethane resin solution with water, the water temperature can be appropriately set to about room temperature to about 70 ° C. When the water temperature exceeds 50 ° C. to 70 ° C., the replacement speed increases, and the formation of the coating layer on the surface of the polyurethane resin solution increases. As a result, a dense coating layer is formed on the outermost surface, but the resulting coating layer is in a non-uniform state. When the water temperature is lower than room temperature, the water replacement rate of the hydrophilic solvent of the polyurethane resin is slow, and time is required for precipitation of the polyurethane resin, resulting in poor efficiency.

  The dropping time for removing the excess resin solution is preferably 20 minutes or less in order to suppress excessive volatilization of the solvent and prevent non-uniform adhesion and non-uniform film thickness. More preferable conditions are 10 seconds to 10 minutes or less. If it is less than 10 seconds, excess resin remains, and the thickness of the PU becomes uneven, which is not preferable. If it exceeds 10 minutes, PU is excessively removed, so that the thickness of the resin is thin and the strength is unfavorable.

(Thread used)
The synthetic fibers, natural fibers, regenerated long fibers (filaments) or spun yarns used in the present invention may be used alone or in combination of two or more according to the purpose. For example, high-strength fibers are used in cut accident protection applications, and yarns made of high-strength polyethylene fibers, aramid fibers, high-strength polyarylate fibers of liquid crystal polymer fibers, and the like are used. For dust generation prevention in a clean room or the like, a long fiber such as polyester fiber, polyamide fiber, rayon fiber, polynosic fiber, polyethylene fiber, aramid fiber, or a crimped yarn thereof is used. The thickness of the yarn used for knitting the knitting gloves used in the examples is 10 to 420 denier, preferably 10 to 100 denier, more preferably 20 to 50 denier.

  As a characteristic of warp knitting, a knitted glove that does not cause fraying (transmission) from the cut surface seen in flat knitting was obtained, and even when the fingertip of the knitted glove was cut after knitting, it became difficult to fray from the cut surface. Since the double raschel knitting machine with the jacquard control mechanism used is computer controlled, the shape of the hand used for coating and the shape and elasticity of the hand are adjusted to match the shape of the hand. The fit and the fit of the product gloves can be adjusted. The conventional fully automatic glove knitting machine (flat knitting machine) can knitting only one piece at a time, but the warp knitting machine can knitting a plurality of pieces at a time, improving productivity.

  When the thickness of the work gloves produced by these manufacturing methods is a solvent-based polyurethane coat, the thickness is 0.4 mm, which is almost half of the thickness of 0.7 g of gloves obtained by the conventional technology. As a result, the feeling of rebound when bent is small and very soft, and the fingertip feel is close to bare hands.

  Examples are described in detail below, but the present invention is not limited to such examples and the like, and the effects of the present invention can be achieved under any conditions that can be imagined by those skilled in the art within the scope of the present invention. Can be obtained. Further changes and modifications are defined by the appended claims.

  The thickness of the yarn that can be used in the double raschel knitting machine having a 20 to 32 gauge jacquard control mechanism used in the embodiment of the present invention is in the range of 10 denier (11 dtex) to 210 denier (231 dtex) as an inelastic yarn. As the elastic yarn, one having a range of 10 denier (11 dtex) to 420 denier (462 dtex) is usually used.

  The yarn used in the present invention is made of synthetic fiber, natural fiber, regenerated fiber long fiber (filament) or spun yarn in addition to the nylon fiber used in the examples. Examples of natural fibers include cotton, wool, silk, hemp and the like. Examples of synthetic fibers and recycled fibers include polyester fibers, polyamide fibers, acrylic fibers, polyvinyl chloride fibers, rayon fibers, polynosic fibers, cupra fibers, acetate fibers, triacetate fibers, promix fibers, and vinylon. Examples thereof include fibers, vinylidene fibers, polypropylene fibers, polybenzoate fibers, polyclar fibers, polyethylene fibers, aramid fibers, and polyurethane fibers. In addition, a rubber thread made of polyurethane rubber, natural rubber, or the like can be used.

  The non-slip elastomer or resin is applied to the palm portion except for PVC coated on the entire surface in the examples and comparative examples. The following polyurethane resin, NBR and NR latex, and polyvinyl chloride resin coating compositions used in the Examples and Comparative Examples are examples of commercially available and comparable products that can be used for forming a coating coating layer. It is described.

  The PU coat was anti-slip processed using polyurethane resin solution Rezamine CU-4340NS (manufactured by Dainichi Seika Kogyo Co., Ltd.) diluted to a solid content of 12% by weight with dimethylformamide. Commercially available polyurethane resin solutions include: Crisbon (registered trademark) MP-812, Crisbon 8006HVLD, Crisbon MP-802 (Dainippon Ink Co., Ltd.), Samprene (registered trademark) LQ-X37L, Samprene LQ-3358, Samprene LQ- 3313A (manufactured by Sanyo Kasei Kogyo Co., Ltd.), RESAMINE (registered trademark) CU-4340, RESAMINEC-4310HV, RESAMINEC-4210 (Daiichi Seika Kogyo Co., Ltd.) can be used.

  As a method of forming the PU coating layer, wet processing can be performed. As shown in FIGS. 8A to 8C, wet processing is performed by attaching a hand 30 to a dipping hand mold 45 and, as shown in FIG. 9, hydrophilic properties such as dimethylformamide, dimethyl sulfoxide, dimethylacetamide, N-methylpyrrolidone and the like. After slowly immersing the hand 30 attached to the hand mold 45 in the polyurethane resin solution 46 completely dissolved in the solvent mainly composed of the organic solvent, the polyurethane resin solution 46 is impregnated and adhered to the hand 30. The method of slowly pulling up the hand mold 45, removing the dripping excess resin solution, immersing the hand mold 45 in water or warm water and replacing the hydrophilic solvent with water or warm water to gel the polyurethane resin into a film quality It is. In this way, as shown in FIGS. 6 and 7, the anti-slip knitted glove 40 is completed.

  The NBR latex composition used for the NBR coating is composed of 100 parts by weight of NBR latex (in terms of solid content), 1.0 part by weight of sulfur, 0.75 part by weight of zinc oxide, 0.2 part by weight of vulcanization accelerator, and antioxidant. An NBR latex composition containing 1.0 part by weight and 0.3 part by weight of a thickener (polyacrylic acid ester), zinc dibutyldithiocarbamate as a vulcanization accelerator, and 2,2′- as an antioxidant Methylene bis-4-ethyl 6-tertbutylphenol is used.

  The NR latex composition used in the NR coat comprises 100 parts by weight of NR latex (in terms of solid content), 1.0 part by weight of KOH (10% by weight), 1.0 part by weight of sulfur, 0.75 part by weight of zinc oxide, A NBR latex composition containing 0.2 part by weight of a sulfur accelerator, 1.0 part by weight of an antioxidant and 0.3 part by weight of a thickener (polyacrylic acid ester), which is a commercially available polyacrylic acid ester Aron A-7075 (manufactured by Toa Gosei Co., Ltd.) was used as a thickener.

  As a method for forming the NBR and NR coating layers, a knitted glove is put on a hand mold and immersed in a coagulant. The coagulant is, for example, a metal salt water or methanol solution such as calcium nitrate. Excess coagulant is removed from the tip of the glove finger bag placed on the hand mold, and the coagulant held on the tip of the glove finger bag is uniformly solidified. Then, after immersing the knitted glove on the hand mold in the rubber compound, for example, drying at 60 to 130 ° C. for 6 to 20 minutes, removing the knitted glove from the hand mold, and performing leaching, then 100 to 100 Heat treatment is performed at 140 ° C. for 20 to 60 minutes. In the thermal method, a knitted glove is covered with a hand mold, heated, dipped in a rubber compound, and then dried. The dipping and drying steps, the leaching after the drying, the heat treatment, and the like are the same steps as the solidification method described above. The concentration of the blend is adjusted to an appropriate concentration so that the rubber coating does not completely penetrate and the adhesive strength does not decrease. The rubber film may be processed by stacking 2 to 3 layers including the anti-slip layer. Covering the inner surface of the knitted glove with rubber is not preferable because there is no contact between the fiber and fingers and slipping occurs inside the glove due to sweat or the like.

  The polyvinyl chloride resin composition used for the PVC coating is composed of 100 parts by weight of a polyvinyl chloride base resin composition (in terms of solid content), 100 parts by weight of a plasticizer, 1.0 part by weight of a thickener, and 3.0 parts by weight of a stabilizer. A plastic resin composition containing diisononyl phthalate (DINP) as a plasticizer, Leoseal QS102 (manufactured by Tokuyama) as a thickener, and SC72 (manufactured by Adeka) as a stabilizer.

  The method for forming the vinyl chloride resin coating layer is not particularly limited, but a glove excellent in adhesiveness can be obtained by subjecting a knitted glove to an oil repellent treatment with an oil repellent in advance. For example, a knitted glove is immersed in an oil repellent such as a fluorine resin or a silicone resin, and dried at 80 to 130 ° C. The oil repellent is about 1 to 3% with respect to the weight of the knitted glove. This knitted glove is put on a hand mold, a vinyl chloride resin (paste) is applied, and heat treatment is performed at about 180 to 210 ° C. for about 10 to 20 minutes.

In the examples, knitted gloves produced by a double raschel knitting machine having a jacquard control mechanism of each gauge number were used.
For each of the examples and comparative examples, nylon yarn subjected to crimping with a count (fineness) described in the table was used. In Examples 1 and 2, a solvent-based polyurethane resin is wet-formed on the fingers and palms of a glove on the original hand of a knitted glove having a total denier number of 20 to 50. In Example 3 and Example 4, NR and NBR coatings were formed on the fingers and palms of a knitted glove having a total denier number of 20, and in Example 5, a knitted glove master having the same denier number was formed. A glove having a non-slip PVC is formed with a coating film on the entire glove.

[Bending resilience]
Using a test piece width of 30 mm and a length of 70 mm, the repulsive force (N) when the test piece is folded in half in the length direction with 4 mm between the plates and sandwiched between the two plates is obtained, and the value is 30 mm wide. The bending repulsion force (mN / mm) was determined by dividing by. The bending repulsion force is preferably 2.5 mN / mm or less.

[Workability]
As a method of evaluating workability, whether or not each size of iron ball can be grasped was evaluated by a questionnaire. This workability evaluation method is called an iron ball test. The diameters of the iron balls used are φ0.5 mm, φ0.8 mm, φ1.0 mm, φ1.2 mm, φ1.5 mm, φ2.0 mm, φ2.5 mm, and φ3.0 mm. When the size of the iron ball that the subject can hold with his bare hands before gloved was confirmed, the average was 1.0 mm.

  In the examples of the present invention, it has been found that an iron ball having the same size as a bare hand can be grasped in a knitted glove in which a solvent-based polyurethane resin is wet-formed. Even when other elastomers were applied, they were much smaller than conventional gloves. In addition, with regard to the results of questionnaires on the feeling of use (workability, feeling of bending, ease of grasping small objects), the gloves were very soft and easy to work with. In addition, because the fingertip feel is very good, it is possible to hold something smaller than before.

[Comparative example]
In Comparative Examples 1 to 3, a solvent-based polyurethane resin was wet-formed on the fingers and palms of the gloves on the original hand of a knitted glove knitted by a flat knitting machine using yarn having a gauge number of 13 to 18 and 140 to 300 denier. doing. In Comparative Examples 5 to 7, non-slip NR, NBR, and PVC were applied to the original hand of a knitted glove knitted with a flat knitting machine using 13 gauge, 280 denier yarn. In Comparative Examples other than Comparative Example 4, seamless knitted gloves created by New-SFG, a fully automatic glove knitting machine manufactured by Shima Seiki Seisakusho with the number of gauges described in the table, were used. In Comparative Example 4, a solvent-based polyurethane resin was wet-deposited on a sewing glove using a fabric manufactured by a circular knitting machine having the gauge number shown in the table. In Comparative Example 7, a glove having a non-slip PVC coated on the original hand of a knitted glove having the same denier number has a coating film formed on the entire glove.

  Tables 1 and 2 show the implementation conditions of each example and comparative example, and the results of evaluation. The reason for this result is that the thickness of the non-slip glove is reduced, specifically 0.7 mm or less, and the thread derived from the hand in the anti-slip glove It is presumed that due to the decrease in the existing amount and the absence of seam allowance, the characteristics obtained from the coating layer, which had not been obtained by the characteristics of the original hand thread, were developed.

  Comparing Examples 1 and 2 and Comparative Examples 1 to 3 that were subjected to PU coating, the non-slip gloves of the example could grab a much smaller one than the comparative example, and the iron balls caught in the example The size is φ1.0 mm, which is the minimum size that can be grasped with bare hands, and it can be seen that in Examples 1 and 2, the same workability as that of bare hands can be obtained. In Comparative Example 4, a PU glove was applied to a sewing glove using a fabric manufactured by a circular knitting machine. Due to the presence of the seam allowance, the fit is poor and the fingertip sensation is hindered, so it was difficult to grasp a small sphere compared to Example 2 having the same thickness and the same total denier number. Further, Comparative Example 4 gave bad results with respect to workability and fit. Compared to Examples 3 to 5 and Comparative Examples 5 to 7 that are made of the same material (NR, NBR, PVC) and are non-slip, the Examples of the present invention have a much larger iron ball I understand that it is small.

The thickness of the non-slip glove is reduced, specifically 0.7 mm or less, and the ratio of the amount of thread derived from the original hand in the anti-slip glove is reduced. The characteristics obtained from the coating layer that was not present were developed. Russell knitted gloves with a coating that can be used for precise assembly of various parts. The working gloves of the present invention have a thickness of 0.4 mm in the case of a solvent-based polyurethane coat, which is nearly half of the minimum thickness 0.7 mm of gloves obtained by the prior art. As a result, the feeling of rebound when bent is small and very soft, and the fingertip feel is close to bare hands, so it is easier to hold something much smaller than before.
From the above results, by applying the configuration of the present invention to a work knitting glove, it is superior in workability compared to a conventional knitting glove by a fully automatic glove knitting machine and a glove made by sewing a thin fabric, especially a fine work using a fingertip. In this case, it was possible to obtain a non-slip glove that was close to a bare hand feeling.

  Further, a test for obtaining conditions suitable for PU coating was performed on the hand 30 of Example 1. There are three basic factors for coating: “viscosity”, “temperature”, and “dipping time”. By changing these three factors, the conditions under which the most suitable work gloves (knitted gloves with anti-slip) can be obtained will be studied. As described above, the hand 30 of the first embodiment uses a nylon fiber yarn having a thickness of “20D / 1 × 1”, and is knitted by a double raschel knitting machine having a gauge number of 28, so that the total number of deniers is increased. 20D warp knitted gloves.

  The PU hand of the hand is a type that coats the entire surface of the glove mainly for the purpose of complete waterproofing (so-called all coat type), and the palm and fingers of the hand excluding the back of the glove for the purpose of reducing hand stuffiness. The type that coats the whole (so-called knuckle coat type) and the type that coats the palm side of the hand and the palm side of the finger except the back side of the glove (so-called back-coating type) There are approximately 4 types of finger gloves that coat up to the vicinity of the first joint (fingertip coat type). In this test, a general palm coat type (a so-called back coat type) was performed.

  Further, the viscosity of the polyurethane resin solution was tested at three types of 250 cps, 500 cps, and 1000 cps. The polyurethane resin solution is made of polyurethane resin and DMF (N, N-dimethylformamide). Therefore, this viscosity is determined by the ratio between the polyurethane resin and DMF. Therefore, the viscosity of the polyurethane resin solution decreases as the DMF ratio increases and increases as the DMF ratio decreases.

  In the hand 30 of the first embodiment, PU coating is performed on the palm and fingers of the hand. The PU coat was anti-slip processed using polyurethane resin solution Rezamine CU-4340NS (manufactured by Dainichi Seika Kogyo Co., Ltd.) diluted to a solid content of 12% by weight with dimethylformamide. As a method for forming the PU coating layer, wet processing is performed. As shown in FIGS. 8A to 8C, the wet processing is performed by attaching the hand 30 to the dipping hand mold 45, and as shown in FIG. 9, hydrophilic properties such as dimethylformamide, dimethyl sulfoxide, dimethylacetamide, N-methylpyrrolidone and the like. The palm part and finger part of the hand 30 attached to the hand mold 45 are immersed in the polyurethane resin solution 46 completely dissolved in a solvent mainly composed of an organic solvent for a certain period of time, so that the polyurethane resin solution 46 is put into the hand 30. After the impregnation and adhesion, the hand mold 45 is slowly pulled up, the excess resin solution dripped is removed, the hand mold 45 is immersed in water or warm water, the hydrophilic solvent is replaced with water or warm water, and the polyurethane resin is made into a film quality. Gel to form. As described above, the solvent-based polyurethane resin 41 is wet-formed on the fingers and the palm of the hand 30 of Example 1 (see FIGS. 5 and 6).

  As described above, the PU coat is affected by the three factors of the viscosity, temperature, and immersion time of the polyurethane resin solution 46, and the quality of the PU coat changes by changing the viscosity, temperature, and time conditions. . The viscosity of the polyurethane resin solution 46 is preferably 10 to 5000 cps, and the temperature of the polyurethane resin solution 46 is preferably room temperature (23 ° C.) to 70 ° C. Prepare a polyurethane resin solution 46 having a viscosity of 250 cps, 500 cps and 1000 cps, set the temperature of the resin solution of each viscosity to 35 ° C. and 50 ° C., set the immersion time to 2 seconds or 1 second, and perform a coating test on the hand 30. went. Tables A to C below are rearranged in order to make the same test results easier to understand. Table A calculates the difference between the average values of each viscosity condition in order to confirm the effect on the viscosity. In order to confirm the effect of temperature, the difference between the respective average values of the two temperatures is calculated, and in Table C, the difference between the respective average values of the two types of time is calculated in order to confirm the effect of the time.

  Tables 3A to 3C show the results of measuring the thickness (unit: mm) of the PU coat at the position of the middle finger of the glove of the coated hand 30. From Tables 3A to 3C, it can be understood that the thickness of the PU coat is not significantly affected by the temperature and the immersion time, but is affected by the viscosity, and is thick when the viscosity is high, and thin when the viscosity is low. . In addition, the average value of the thickness of PU coat is 0.4 mm or less.

  Table 4A-4C represents the result of having measured the thickness (unit mm) of PU coat of the position of the four trunk | drum of the glove of the coated hand 30. From Tables 4A to 4C, it is understood that the thickness of the PU coat is not greatly affected by the temperature and the immersion time, but is affected by the viscosity, and increases when the viscosity is high, and decreases when the viscosity is low. can do. In addition, the average value of the thickness of PU coat is 0.4 mm or less.

  Therefore, the thickness of the PU coat is affected by the viscosity in the three elements, and the viscosity may be lowered in order to reduce the thickness. If the viscosity is low, the urethane ratio in the polyurethane resin solution 46 becomes low. In fact, if the coating is replaced with water, the amount of urethane coating on the glove is reduced and the thickness is considered to be thin.

  Table 5A-5C represents the result of having measured the bending repulsion force (mN / mm) of PU coat of the gloves of the coated hand 30. The bending repulsive force is one index indicating the softness of the PU coat of the glove. From Tables 5A to 5C, the bending repulsion force of the PU coat is not significantly affected by the temperature, but is affected by the viscosity and the immersion time, and is particularly affected by the viscosity. The viscosity becomes high when the viscosity is high. Soft when low. In addition, the immersion time has an effect under low viscosity conditions. When the immersion time is long, it becomes hard (high bending repulsive force), and when the immersion time is short, it becomes soft (low bending repulsive force). Therefore, the PU coat becomes softer when the viscosity is lower and the immersion time is shorter. The lower the viscosity, the thinner the PU coat, and the lower the elastic modulus of the glove.

  Table 6A-6C represents the result of the iron ball test of the glove 40 in which the PU 30 is coated on the hand 30. The iron ball test is a test for evaluating the workability of the glove 40 coated with the PU coat by the size (mm) of the iron ball that can be grasped. That is, this is a test for detecting the size (unit: mm) of an iron ball that can be held by a glove 40 coated with a PU coat. From Tables 6A to 6C showing the results of the iron ball test, the size (mm) of the iron ball that can be gripped by the PU coat is not significantly affected by the viscosity and the immersion time, but is affected by the coating temperature of the polyurethane resin solution 46. When the temperature is high, the workability is high, and when the temperature is low, the workability is low. When workability is high, small objects can be grasped, and when workability is low, small objects cannot be grasped. Therefore, the higher coating temperature of the polyurethane resin solution 46 is more effective in terms of workability than the normal temperature assumed in the prior art. First, the lower the viscosity, the lower the amount of urethane, so that the coating is thin and the fingertip workability is improved. In addition, when the temperature of the polyurethane resin solution itself is increased, the apparent viscosity is lowered, and the coating amount on the surface of the glove is further lowered, so that the workability of the fingertip is further improved.

  From Tables 3A to 6C, when the temperature of the polyurethane resin solution is increased, the apparent viscosity is decreased. Under low-viscosity conditions, the amount of urethane is small, thinly coated, and the fingertip fit is improved. This is because the temperature effect of the polyurethane resin solution should be lower, and under higher conditions, increasing the temperature will decrease the apparent viscosity, reduce the coating amount on the glove surface, and increase the fit of the fingertips. It is.

  For the performance of the coated gloves, the thickness of the PU coat, the softness (bending repulsion force), and the size of the iron ball that can be gripped (workability) are important. Satisfying these performances can be achieved by lowering the viscosity of the polyurethane resin solution, shortening the immersion time, and raising the temperature of the polyurethane resin solution.

  Furthermore, from the next experiment, it was possible to confirm that the quality of the PU coat can be changed based on the relationship between the hand mold 45 and the hand 30. The relationship between the hand mold 45 and the hand 30 is expressed as a circumference ratio. As shown in FIGS. 8A and 8B, the circumferential length ratio is a percentage calculated by (hand type perimeter D1−hand perimeter D2) / hand perimeter D1 of the four torso and is also an elongation rate. For example, if the hand mold perimeter D1 and the master hand perimeter D2 are the same, there is almost no elongation. Further, when the length of the hand circumference D2 is longer than that of the hand mold circumference D1, the circumference ratio is negative because it does not stretch and bumps. If the hand circumference D2 is shorter than the hand mold circumference D1, when the hand 30 is put on the hand mold 45, the whole is pulled, the elongation increases, and the circumference ratio is positive.

  One common working glove in the prior art is a glove in which a hand is made of polyester yarn, knitted by a seamless knitting machine having a gauge number of 13, and a palm is coated with a polyurethane coating. The circumference ratio of this glove is about 17%. The relationship between this common coat type glove hand and hand type, including work gloves of other gauge numbers, is 1: 1 in terms of dimensional ratio and about 20% or less in terms of perimeter. This general working glove is produced with a uniform PU coat thickness by using a hand shape that is almost perfect for the glove's original hand. The original hand of this application is knitted with Russell knitting, and is very thin and highly flexible compared to general gloves. However, since the shrinkage of the knitted fabric is weaker than that of a general hand, If coating was performed at the same ratio, sagging of the original hand occurred and wrinkles appeared on the coated surface.

  In order to solve this problem, the hand 30 of the present application increases the circumference ratio of the hand 30 and the hand mold 45, and increases the tension when fitting the hand hand 45 of the glove, thereby preventing sagging and the like. Optimal PU coating is now possible. An experiment was conducted to obtain this appropriate circumference ratio. Polyurethane resin coating is applied to the hand 30 with a circumference ratio of 0%, 27%, 36%, 38%, 42%, PU coating thickness, bending repulsion force (softness), iron ball test (grabbing) An experiment was conducted on the workability of evaluating the size of an iron ball. Table 7 shows the relationship between the circumference ratio, the thickness of the PU coat, the bending repulsion force, and workability.

  The original hand of the present application with a circumference ratio of 27% caused wrinkles due to sagging when placed on a hand mold, and it was not possible to perform a beautiful coating. As can be seen from Table 7, the higher the circumference ratio (elongation rate), the thinner the PU coat. In order to keep the thickness of the PU coat at 0.4 mm or less, it becomes possible by setting the circumference ratio to 35% or more. It is assumed that when the circumference ratio is 35% or less, a gap is generated between the hand mold and the hand, and the coating agent penetrates to that extent and exceeds the target thickness. Since the conventional hand is thick and non-erodible, it is not assumed that a hand that is smaller than the hand type is used. The original hand of Russell knitting of this application is a very thin thread and excellent in elasticity, so it is a problem that has been discovered, and since it is an improvement means to solve it, it can be easily conceived with conventional PU coated gloves is not.

  The anti-slip knitted gloves (work gloves) of the present application have different numbers of stitches on the coated surface (the palm side) and the non-coated surface (the back side of the hand). The relationship between the number of stitches on the coated surface (the palm side) and the number of stitches on the non-coated surface (the back side of the hand) was expressed as a stitch ratio. The stitch ratio is a percentage calculated by the number of stitches on the coated surface (the palm side) / the number of stitches on the non-coated surface (the back side of the hand). Table 8 shows the relationship between the perimeter length ratio and the stitch ratio, and it can be understood that the glove with the increased perimeter ratio has a lower number of stitches on the coated surface than the non-coated surface.

  The anti-slip knitted glove of the present invention is a work knitted glove having greatly improved workability, and is thin, soft and durable that can be used with bare hands for assembling various parts, particularly assembling precision parts. Russell knitted gloves with good coating.
