Description

  The present invention relates to a sewing glove, and more particularly relates to a sewing glove excellent in wearing comfort with a soft feeling at the stitching portion of the sewing glove and less feeling of tingling.

  As a glove excellent in cutting prevention, for example, Patent Document 1 describes an invention of a glove using a crimped yarn of para-aramid fiber, and discloses a sewing glove obtained by cutting a fabric into a hand shape and sewing it. However, the stitching part has a strong feeling of wear and is inferior in wearing comfort such as fit and soft feeling. Incidentally, in a knitted glove by a glove knitting machine, since there is no stitched portion, such a problem of wearing comfort does not occur.

In addition, it includes a composite yarn obtained by a known composite means such as a composite crimping process such as cross-twisting, mixed fiber, covering, and composite false twisting process. preferable.
For example, for the purpose of suppressing a decrease in the tensile strength of the polyketone fiber by receiving strong ultraviolet rays outdoors, for example, in the form of a fiber or a woven or knitted fabric, for example, one or two types of benzophenone, benzotriazole, and hindered amine It is preferable to contain an ultraviolet absorber such as the above combination and / or an ultraviolet shielding agent. Examples of the ultraviolet shielding agent include fine particles such as titanium oxide, iron oxide, and cerium oxide, and the average particle size is preferably 0.01 to 0.6 μm. Examples of the method of inclusion include a method in which a fiber or a woven or knitted fabric is provided with or coated with a resin or film containing an ultraviolet absorber and / or an ultraviolet shielding agent. The content of the ultraviolet absorber and / or ultraviolet shielding agent is preferably 0.001 to 10% by mass with respect to the mass of the resin or film.

The feature of the present invention resides in that the polyketone fiber is used as a sewing glove using the front surface and / or the back surface of the glove. Furthermore, it may be used for at least one of the front surface, the back surface and the intermediate layer of the glove, and is preferably used for either the back surface or the intermediate layer to form a sewing glove.
The content of polyketone fibers in the sewing gloves is preferably 20% or more, particularly 30% or more, more preferably 50% or more, and further preferably 70% or more and 100% or less. Therefore, you may comprise a sewing glove in combination with fibers other than polyketone fibers, natural leather, or artificial leather.

  Examples of fibers other than polyketone fibers include natural fibers such as cotton and wool, cellulose fibers such as rayon fibers and lyocell fibers, polyester fibers, polyamide fibers, aramid fibers (para and meta), polyvinyl alcohol fibers, poly ( (p-phenylenebenzobisoxazole) fiber, ultrahigh molecular weight polyolefin fiber, carbon fiber, ceramic fiber, glass fiber, metal fiber, and other known various fibers may be used in combination. As the mixing means, known mixing means such as cross-twisting (double yarn, three yarns, etc.), mixed fiber, covering (single or double), and knitting and weaving may be employed. For example, the front and / or back surface of the glove may be mixed with 100% polyketone fiber or a fiber other than polyketone fiber, or the front or back surface may be mixed with 100% polyketone fiber or fiber other than polyketone fiber, May be composed of 100% fiber other than polyketone fiber. In addition, as these various fibers to be used in combination, those having various thread forms defined by the polyketone fiber thread form can be used.

  The sewing glove of the present invention may adopt various forms as necessary. For example, using a raised or pile (cut, loop) fabric, the raised or pile surface is the inner side of the glove (surface that contacts the skin). Improves the touch by placing the fiber on the inside of the glove, using a fiber with a fine single yarn fineness (for example, 3 dtex or less) on the inside of the glove, and a thick single yarn fineness (for example, 3 dtex or more) on the outside Cutting property can be improved using a fiber. Moreover, you may provide the fastening part using the various elastic fibers represented by the polyurethane type in the wrist, the palm, the back, and a part or all of the finger bag.

  Furthermore, known various treatments, for example, an elastomer such as vinyl chloride resin, latex, natural rubber, synthetic rubber, etc. on part or all of the glove for the purpose of imparting anti-slip properties, etc. Depending on the means, resin coating may be performed by coating or lamination. Further, it may be coated or laminated with a gas permeable and liquid impermeable elastomer such as porous or nonporous polyurethane or porous polytetrafluoroethylene (PTFE) in order to prevent stuffiness. An elastomeric glove such as rubber may be further processed on the glove. A special curing agent may be coated to prevent puncture. For example, when a resin-coated fabric is used on the palm side and a breathable mesh fabric on the back side of the hand or a fabric having moisture permeability such as a porous or nonporous film is used, the feeling of stuffiness is reduced. In addition, when resin-coated on a fabric having fluff, if necessary, fluffing and fluffing (heat setting or sizing) may be performed by known means.

Further, natural leather such as pig leather or artificial leather may be used on the surface of the sewing glove, and the back surface may be constituted by a cloth using polyketone fiber.
The sewing thread for sewing the gloves may be composed of polyketone fibers or may be composed of fibers other than polyketone fibers.
Examples of the shape of the glove include various types such as a five-finger type and a mittens type.
Specific examples of the use of sewing gloves include iron making, welding, painting, fire fighting, car racing racing, etc. In the present invention, particularly in the precision machine industry, because of excellent wearing comfort. It is suitable for fields that require delicate work, such as the aircraft industry, information equipment industry, medical surgery, and hygiene.
Furthermore, the sewing glove of the present invention has excellent wearing comfort, and in particular, the sewing glove using filament thread is for protecting medical personnel such as doctors from scalpels and injection needles in medical practice such as surgery. It is optimal as a so-called inner glove used inside an elastomer glove such as rubber.

Hereinafter, the present invention will be described more specifically based on examples, but the present invention is not limited to these examples.
The measurement method and evaluation method in the present invention are as follows.
(1) Tensile strength, tensile elongation, tensile elastic modulus Measured according to JIS-L-1013.

X: The feeling of creaking at the stitched portion is strong, and the fit and softness are inferior.
(3) Cut resistance According to JIS-T-8052.

[Example 1]
Polyketone fiber (manufactured by Asahi Kasei Fibers Co., Ltd .; trade name: Cyvalon; tensile strength 18 cN / dtex, tensile elongation 5%, tensile elastic modulus 350 cN / dtex) Warp density 58 / 2.54 cm, weft density 47 / 2.54 cm). Using this woven fabric, cutting and sewing was performed along a bill to obtain a normal five finger glove.
As a result of evaluating the obtained sewing gloves, they were excellent in wearing comfort (◯ to Δ) and wearing comfort. The cut resistance was excellent at 9N.
[Comparative Example 1]
As a result of producing and evaluating a sewing glove in the same manner as in Example 1 using para-aramid fiber instead of polyketone fiber, it was inferior in wearing comfort (Δ to ×) and wearing comfort in comparison with Example 1. there were. The cut resistance was 8N.

  The present invention provides a sewing glove that has a soft feel and has a soft feeling and is less worn and comfortable to wear.
