Description

  The present invention relates to a work glove with improved strength and cut resistance and a method for producing the same, and more specifically, waterproof and oil resistance, high strength and cut resistance, and excellent fit. The present invention relates to a work glove having a good softness and excellent usability and a method for manufacturing the same.

In general, work gloves coated with a polymer material are manufactured by, for example, immersing a sewing glove made of cotton knitted fabric several times in a polymer material such as natural rubber latex or polyvinyl chloride solution, and drying and solidifying it. (Hereinafter referred to as Prior Art 1). This type of so-called rubber glove, which is called a work glove, is excellent in waterproofness and oil resistance, but is not always sufficient for work that requires strength, cut resistance, etc., such as work for handling oyster shells, etc. There were strength problems such as early breakage.
Moreover, in this prior art 1, there exists one which raised the intensity | strength by increasing the frequency | count of immersion to said polymeric material and increasing the thickness of a coating layer. However, in this case, there is a problem that the obtained working gloves are thick and hard to use.

  In order to solve this problem, there has been proposed a work glove in which a seamless glove is arranged outside an inner layer glove made of a sewing glove and a polymer material is infiltrated into the glove and dried (see, for example, Patent Document 1 below). , Referred to as Conventional Technology 2). This work glove of prior art 2 has improved strength and cut resistance due to the placement of seamless gloves, and the above polymer material penetrates the entire seamless gloves and also on the outer surface side of the inner layer gloves. In order to penetrate, the inner layer glove and the seamless glove are firmly bonded by this polymer material. In addition, since this polymer material does not penetrate into the inner surface of the inner layer glove, there is an advantage that the fit property of the inner layer glove remains as it is.

However, the work glove of the above-mentioned prior art 2 has a double structure in which a seamless glove is arranged outside the inner layer glove, and the polymer material is impregnated to the inside of the knitting yarn of the seamless glove. Compared with the rubber glove of the above-mentioned prior art 1, it becomes hard and the feeling of use is inferior and the hand may be easily fatigued.
The technical problem of the present invention is to solve these problems, have waterproofness and oil resistance, high strength and cut resistance, etc., excellent fit, softness is maintained well, and excellent usability Another object of the present invention is to provide a working glove and a manufacturing method thereof.

In order to solve the above problems, the present invention is configured as follows, for example, based on FIGS. 1 to 5 showing an embodiment of the present invention.
That is, the present invention 1 relates to a work glove, and includes an inner layer glove (2) and a seamless glove (3) disposed on at least a part of the outer glove (3). Yes, the surface of the knitting yarn (5) of the seamless glove (3) subjected to the water repellent treatment is covered with the polymer material (4) and the polymer material (4) is infiltrated into the stitch (6). The polymer material (4) is infiltrated into part of the outer surface side of the inner layer glove (2) through the stitch (6) of the seamless glove (3).

  The present invention 2 relates to a method for manufacturing a work glove, wherein a seamless glove (3) having a water-repellent finish is arranged on at least a part of the outer side of the inner layer glove (2), and then a stitch ( 6) The liquid polymer material (4) is infiltrated into 6), and the polymer material (4) is infiltrated into a part of the outer surface side of the inner layer glove (2) through the stitch (6). The polymer material (4) is solidified.

  Since the above-mentioned seamless gloves are water-repellent, a water-repellent layer is formed on the surface of the knitting yarn. For this reason, the polymer material does not penetrate between the fibers inside the knitting yarn, but covers the surface of the knitting yarn and penetrates into the stitch. The polymer material that has penetrated into the stitch of the seamless glove passes through the stitch and penetrates into the inner layer glove. At this time, since the polymer material does not penetrate into the knitting yarn of the seamless glove, this polymer material hardly penetrates into the portion facing the knitting yarn on the outer surface side of the inner layer glove. It easily penetrates into the part facing the stitch. As a result, the polymer material penetrates into a part of the outer surface side of the inner layer glove, and the inner layer glove and the seamless glove are firmly bonded to each other by the penetrated polymer material.

  Here, the polymer material is not limited to a specific material as long as it is liquid when infiltrated into an inner layer glove or seamless glove and can be solidified by drying or the like thereafter. Specific examples include natural rubber latex, synthetic rubber latex such as NBR (acrylonitrile, butadiene, rubber), polyvinyl chloride resin, polyurethane resin, etc., depending on the desired oil resistance, chemical resistance, etc. It is selected appropriately.

  The water repellent treatment applied to the seamless glove may be performed at the stage of knitting yarn, or may be performed after knitting the glove. The water repellent used in this processing is not limited to a specific type, and examples thereof include a fluorine water repellent and a silicon water repellent.

  The inner layer glove may be either a sewn glove or a seamless glove, and may be entirely made of cotton fiber. However, if the inner layer glove is formed of cotton and synthetic fiber, the strength of the inner layer glove itself can be increased. In addition, since the permeability of the polymer material is increased, the adhesive strength with a few polymer materials that have passed through the stitches of the seamless glove can be increased, which is preferable. In this case, the inner layer glove may be knitted with cotton yarn and synthetic fiber yarn, or may be knitted with knitting yarn made of cotton and synthetic fiber. Moreover, the ratio of this cotton and a synthetic fiber is not limited to a specific ratio, For example, although the ratio of a synthetic fiber is set to 20 to 80%, from the viewpoint of the feel and intensity | strength of the work gloves obtained, Preferably, it is set to 40 to 60%.

  On the other hand, the above-mentioned seamless gloves may be cotton knitted gloves knitted with fine threads, but if synthetic fibers are used, the overall strength of the work gloves can be increased and the permeability of the polymer material is excellent. Therefore, the adhesive strength with the inner layer gloves can be increased, which is preferable.

  As a synthetic fiber used for this seamless glove or the above-mentioned inner layer glove, for example, wooly nylon thread or polyester thread can be used. In particular, these seamless gloves can include high-performance fibers such as aramid fibers, ultra-high strength polyethylene fibers, wholly aromatic polyester fibers, and polyparaphenylene benzobisoxazole fibers, in which case the strength of the work gloves In addition, while maintaining high cut resistance and the like, the fibers can be thinned to form a seamless glove, which is preferable because a work glove that is soft and has good fit can be obtained.

  The seamless glove described above can include elastic yarn such as wooly nylon yarn or rubber yarn in the knitting yarn. In this case, since the seamless glove has elasticity, the entire work glove can be softened and a good feeling of use can be exhibited, which is preferable. In particular, when a knitting yarn excellent in stretchability is used, there is an advantage that the work gloves can be made to correspond to a plurality of sizes.

  The seamless glove does not need to cover the entire outer surface of the inner layer glove, and may be disposed only at a site where strength, cut resistance, etc. are particularly required. Specifically, for example, the shape of only the finger portion, the shape of only the torso portion of the hand excluding the finger portion, the shape of the fingertip having good flexibility excluding only the finger tip, and the like can be given. In these cases, it is possible to improve the strength of a required part and the like, and there is an advantage that a working glove can be obtained at a low cost since the amount of seamless gloves used is small.

  The seamless gloves may be arranged outside the inner layer gloves, and the arrangement method and the polymer material penetration method are not limited to specific methods. For example, it is conceivable to apply a polymer material and infiltrate it, but usually, an inner layer glove is attached to a three-dimensional hand mold, a seamless glove is attached to the outside, and this is immersed in a liquid polymer material. Done in

  At this time, if the above-mentioned inner layer glove is attached to a three-dimensional hand shape slightly curved to the palm side, and the above-mentioned seamless glove is disposed outside the inner layer glove, the seamless glove has a knitting density on the palm side compared to the back side of the hand. Become higher. For this reason, the polymer material that permeates this seamless glove passes through the wide stitch on the back side of the wide hand of the stitch and firmly adheres to the wide adhesive area. Is done. As a result, the obtained work gloves can move smoothly in accordance with the opening and closing operation of the hand, and are preferable because they can exhibit a soft and good feeling of use.

  Since the present invention is configured and operates as described above, the following effects can be obtained.

(1) Seamless gloves with water repellent finish are covered with a polymer material on the surface of the knitting yarn, and the polymer material penetrates into the stitches. Can be used for various work. In addition, seamless gloves are arranged on the outer surface of the inner layer gloves, and the inner layer gloves and the seamless gloves are well bonded to each other through the permeated polymer material, so that the tensile strength and tear strength are excellent and wear resistance is also improved. Excellent in cut and cut resistance. Moreover, since the polymer material does not penetrate into the inner surface of the inner layer glove, excellent fit similar to that of a conventional sewing glove can be obtained when the operator wears it.

(2) Since the polymer material does not penetrate between the fibers inside the knitting yarn of the seamless glove due to the water repellent finish, the movement of the knitting yarn fibers is allowed and the flexibility is maintained. Moreover, only the polymer material that has passed through the stitches of the seamless glove penetrates into the inner layer glove, and the polymer material hardly penetrates into the part corresponding to the knitting yarn of the seamless glove. A large amount of polymer material is prevented from penetrating. As a result of these, the softness of the work gloves is well maintained and an excellent feeling of use is exhibited.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show an embodiment of the present invention, FIG. 1 is a partially cutaway view of a work glove, and FIG. 2 is an enlarged plan view of a main part of a seamless glove schematically showing a state in which a polymer material has permeated. 3 is an enlarged cross-sectional view of the main part of the working glove schematically showing a state in which the polymer material has permeated, FIG. 4 is an external view of a three-dimensional hand shape used for manufacturing the working glove, and FIG. It is a side view which shows the immersion process.

  As shown in FIG. 1, this working glove (1) comprises a sewing glove (2) as an inner layer glove and a seamless glove (3) arranged outside the glove. From the outside, natural glove latex, NBR, etc. The polymer material (4) such as synthetic rubber latex is impregnated and solidified.

  The above-described sewing gloves (2) are knitted using yarns obtained by combining synthetic fiber yarns such as wooly nylon yarns and polyester yarns and cotton yarns in a ratio of 50:50. On the other hand, the seamless glove (3) is knitted into a thin glove such as a 15 gauge knitting or an 18 gauge knitting using a high-performance fiber such as an aramid fiber or an ultra-high strength polyethylene fiber. For this reason, this work glove as a whole is also formed thin, and a feeling of use close to bare hands is obtained. Further, the seamless glove (3) is knitted into a glove and then subjected to a water repellent treatment with a fluorine water repellent or a silicon water repellent.

  As shown in FIG. 2 and FIG. 3, the polymer material (4) covers the surface of the knitting yarn (5) of the seamless glove (3), and is formed in the stitch (6) of the seamless glove (3). Penetrating. However, since the seamless glove (3) is water-repellent, a water-repellent layer (7) is formed on the surface of the knitting yarn (5). 5) It does not penetrate between the fibers.

As shown in FIG. 3, the polymer material (4) that has penetrated into the stitch (6) of the seamless glove (3) passes through the stitch (6) to the outer surface side (seamlessly) of the sewing glove (2). It penetrates a part of the glove interface). That is, the polymer material (4) penetrates into the portion of the outer surface of the sewing glove (2) facing the stitch (6) of the seamless glove (3), and the seamless glove (3) It hardly penetrates into the part facing the knitting yarn (5).
The cotton contained in the sewing glove (2) is less permeable to the polymer material (4) than the synthetic fiber, so the polymer material (4) is placed on the outer surface side of the sewing glove (2). It penetrates only and does not penetrate the inner surface of the sewing glove (2). For this reason, this work glove (1) is equipped with the excellent fitting property of the sewing glove (2).

Since the sewing glove (2) is made of cotton yarn and synthetic fiber yarn, the polymer material (4) penetrates well at the part facing the stitch (6) of the seamless glove (3). The sewing glove (2) and the seamless glove (3) are firmly bonded to each other through the polymer material (4).
At this time, the sewing glove (2) has almost no permeation of the polymer material (4) at the part facing the knitting yarn (5) of the seamless glove (3). For example, as shown in FIG. In 3), it is in a state of being bonded in a number of points. For this reason, the above-mentioned sewing glove (2) maintains high flexibility while firmly bonding to the seamless glove (3). Further, the seamless glove (3) is covered with the polymer material (4), but the polymer material (4) does not penetrate into the knitting yarn (5). 3) The flexibility itself is maintained.
As a result of these, the work glove (1) is softly formed as a whole, and exhibits excellent usability and good workability.

  As shown in FIG. 1, the work glove (1) is slightly worn toward the palm (8) when not worn, and the stitch density on the palm (8) side of the seamless glove (3) is the back of the hand. (9) It is formed to be higher than the side. For this reason, the stitch (6) of the seamless glove (3) is wide on the back (9) side of the hand, and the bonding area of the polymer material (4) is widened to firmly adhere to the sewing glove (2). is there. On the other hand, the stitch (6) is clogged on the palm (8) side, the adhesion area by the polymer material (4) is narrow, and it is gently adhered to the sewing glove (2). Also, since there is little polymer material (4) penetrating into the stitch (6) on the palm (8) side, this height is increased when the work glove (1) is bent toward the palm (8) and the hand is closed. Less resistance due to molecular material (4). As a result, the hand opening / closing operation can be performed smoothly and easily.

Next, the manufacturing procedure of the above working gloves will be described.
First, the above-mentioned sewing glove (2) is attached to the three-dimensional hand mold (10) shown in FIG. 4, and the above-mentioned seamless glove (3) subjected to water-repellent finish is attached to the outside thereof. In this embodiment, the seamless glove (3) is knitted and then subjected to water repellent treatment to reduce the risk of fouling in the knitting process. Also good.

  The three-dimensional hand mold (10) is slightly curved toward the palm (8) as shown in FIG. Therefore, in the seamless glove (3) attached to the three-dimensional hand mold (10), the stitch (6) is narrow on the palm (8) side and wide on the back (9) side.

  Next, as shown in FIG. 5, the liquid polymer material (4) such as latex contained in the dipping tank (11) with both gloves (2, 3) attached to the three-dimensional hand mold (10). Soak as many times as necessary. Then, after vulcanizing at a predetermined temperature to solidify the polymer material (4), both gloves (2, 3) are removed from the three-dimensional hand mold (10) and dried. Then, the work glove (1) shown in FIG. 1 is obtained by cutting an unnecessary part of the hem (12).
