Description

  The present invention relates to a moisturizing glove and a manufacturing method thereof. More specifically, the present invention relates to a moisturizing glove that does not cause rough hand skin even when used for a long time and has a flexible feeling of use, and a method for manufacturing the same.

  Conventionally, rubber work such as natural rubber and acrylonitrile-butadiene rubber (NBR) and soft vinyl chloride resin gloves are used during water work such as cooking and washing. Many of these gloves have a flocking treatment with short fibers such as piles on the inner surface in order to improve detachability and keep warm during water work.

  However, such gloves are used repeatedly or for a long time, and moisture accumulates on the inner surface of the gloves due to sweating from the hands, etc., resulting in the formation of harmful bacteria and wrinkles. However, there are problems such as rough skin on the user's hand, and skin diseases in some cases.

  In order to solve these problems, a glove in which an antibacterial agent is blended in a glove base, a glove in which an antibacterial pile is planted on the inner surface of the glove (Patent Document 1), and an emulsion in which an antibacterial agent is added to the inner surface of the glove body A work glove (Patent Document 2) or the like in which a fine hair material is attached via a system adhesive has been proposed.

However, the antibacterial and antifungal effect on the inner surface of the glove with the antibacterial agent blended with the glove base is insufficient, and the antibacterial pile piled on the inner surface of the glove and the adhesive added with the antibacterial agent Gloves with fine hair materials attached via the antibacterial agent etc. elute inside the glove and kill the resident bacteria in the skin. As a result, there was a problem that consideration for the user's hand was insufficient.
JP-A-63-135504 Japanese Utility Model Publication No. 63-102719

  Therefore, repeated use and prolonged use can prevent rough skin of the hand without affecting the resident bacteria on the skin, and development of a glove having an excellent moisturizing effect is desired. It was.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors have applied the short fibers treated with the moisturizing component to the inner surface of the glove base, thereby giving the hand an excellent moisturizing effect and weak skin. It is possible to provide gloves that are gentle to the user's hand, and if these short fibers are applied with an adhesive containing an antibacterial or antifungal agent, antibacterial activity can be prevented in the glove without affecting normal bacteria. -The present invention was completed by finding that it can provide an antifungal action.

  That is, the present invention is a glove in which a short fiber is attached to the inner surface of a glove base made of rubber or a synthetic resin, and a part or all of the attached short fiber is treated with a moisturizing component. It provides a moisturizing glove characterized.

  Moreover, this invention provides the said moisture retention glove in which the adhesive agent used for adhesion contains an antibacterial agent and / or a fungicide.

  Furthermore, this invention provides the manufacturing method of the said moisture retention glove.

  The moisturizing glove of the present invention has a structure in which short fibers treated with a moisturizing component are attached to the inner surface of a glove formed of rubber, synthetic resin, etc., and thus has an excellent moisturizing effect on the hand. In addition to moisturizing the hand, it is possible to provide a rubber or synthetic resin glove that prevents rough skin of the hand and has a flexible feeling of use.

  In addition, when an antibacterial agent or antifungal agent is added to the adhesive used for adhering short fibers, it suppresses the generation of microorganisms and wrinkles inside the glove without affecting the resident microorganisms on the skin surface. And the generation of bad odors can be prevented.

  The moisturizing glove according to the present invention is characterized in that a part or all of the short fibers applied to the inner surface of the glove base are treated with a moisturizing component. In the present specification, “adhesion” refers to a state in which short fibers are randomly attached to the inner surface of the glove with a natural feeling.

  The substrate of the moisturizing glove of the present invention is manufactured from rubber or synthetic resin, specifically, a known material such as ceramic, metal, glass or wooden in a resin liquid such as latex or synthetic resin dispersion. After the hand mold is immersed, the resin liquid adhering to the hand mold is solidified.

  Examples of latexes used as resin liquids include synthetic rubbers such as acrylonitrile-butadiene rubber (NBR), chloroprene rubber (CR), styrene-butadiene rubber (SBR), isoprene rubber (IR), polyurethane (PU), and special rubber Mention may be made of rubber. These synthetic rubbers can be used as they are as resin liquids that are raw materials for glove bases. However, these synthetic rubbers are blended with vulcanizing agents, vulcanization accelerators, softeners, fillers, etc. It is good.

  Examples of the synthetic resin dispersion include a dispersion in which a synthetic resin such as vinyl chloride or acrylic is dispersed in a plasticizer or a solvent.

  Next, short fibers treated with a moisturizing component are attached to the inner surface of the glove base.

  The short fiber used for the deposition is not particularly limited, and any of natural fibers, synthetic fibers, and chemical fibers may be used. For example, natural fibers such as cotton, wool, silk, rayon, cupra, acetate, Examples thereof include chemical fibers such as lyocell, and synthetic fibers such as polyethylene, polypropylene, polyester, and nylon. Among these, it is preferable to use chemical fibers such as rayon or natural fibers such as cotton from the viewpoint of easiness of treatment with a moisturizing component described later.

  The short fiber may have a thickness in the range of 0.1 to 50 dtex, preferably 0.5 to 5 dtex. Moreover, the length of 0.1-150 mm, Preferably, the thing of 0.5-3.0 mm can be used.

  On the other hand, as a moisturizing component used for treating short fibers, any moisturizing component that has been conventionally used in the field of cosmetics and the like can be used without particular limitation. Examples of the moisturizing component include natural extract such as squalane, squalene, hyaluronic acid, chondroitin, propylene glycol, polyethylene glycol, sorbit, urea and the like. One of these can be used alone, or two or more can be used. Can be used in combination. In the present invention, it is particularly preferable to use squalane among the moisturizing components described above.

  As a method for treating the short fiber with the moisturizing component, it can be treated by a conventionally known method. For example, a method of spinning a mixed solution in which a moisturizing component is mixed with a raw material solution during fiber production to prepare a fiber kneaded with the moisturizing component, and then chopping the fiber into short fibers, Examples thereof include a method of adhering the short fiber with a moisturizing component by padding or spraying before or after chopping. When using chemical fibers such as rayon, it is preferable to use the former method from the viewpoint of sustainability of the effect, for example, the method disclosed in JP 2000-192326 A can be used. . On the other hand, when natural fibers such as cotton are used, the latter method is preferably used. In addition, as a moisturizing component kneaded into the fiber, commercially available fibers such as Papolis (registered trademark) (1.0% squalane kneaded into rayon: made by Ohmi Kenshi) are shredded, It can also be used as a short fiber.

  The content of the moisturizing component in the short fiber treated with the moisturizing component (hereinafter referred to as “treated short fiber”) is not particularly limited, but is 0.3 to 30% by mass with respect to the entire treated short fiber. (Hereinafter simply referred to as “%”), and more preferably 1 to 5%. When the content of the moisturizing component in the short fiber is less than 0.3%, the moisturizing effect may not be exhibited. When the content is more than 30%, the physical properties of the fiber may be lowered, or the fiber itself. However, the moisture retaining component cannot be fully retained and the moisture retaining component is deposited on the surface of the fiber, which may cause discomfort during use.

  The moisturizing glove of the present invention can be manufactured, for example, using any of the following methods.

  First, as a manufacturing method 1, after making a resin liquid adhere to the glove-type surface, this resin liquid adheres a processing short fiber to the surface in a sol state or a semi-gel state, and solidifies the resin liquid after that. And a method of attaching short fibers to the surface of the glove.

  Moreover, as the production method 2, there is a method in which a resin liquid is attached to the surface of the glove mold, and an adhesive is applied to the glove base obtained by solidifying the resin liquid, and the treated short fibers are further adhered.

  Among these methods, production method 1 is a method in which latex or synthetic resin dispersion is dipped into a glove mold and then pulled up, or the resin liquid is showered on the entire glove mold to attach the resin to the entire mold, and rubber or synthetic In this method, the treated short fibers are planted while the resin is in a sol state or a semi-gel state, and then the entire glove mold is solidified and molded.

  In the case of this production method, when the glove base is rubber, the time for immersing the glove mold in latex is about 20 to 60 seconds, and the treated short fibers may be planted immediately thereafter. Moreover, although the conditions for drying and crosslinking differ depending on the type of latex, it is generally preferable to dry at 80 to 120 ° C. and then heat at 100 to 130 ° C. for about 20 to 40 minutes.

  When the glove base is a synthetic resin such as polyvinyl chloride, the time for immersing the glove mold in the dispersion is about 30 to 60 seconds, and the treated short fibers may be applied before heating. Moreover, although the conditions which gelatinize differ with the components of a synthetic resin, generally it is preferable to heat at 200-250 degreeC for about 5-10 minutes.

  In manufacturing method 2, a glove base is obtained by applying a resin liquid such as latex or synthetic resin dispersion to the surface of the glove mold and then solidifying, and then applying an adhesive to the surface of the glove base and then processing. This is a method for depositing short fibers. In this production method, the means for converting the glove base into a resin may be performed in accordance with the production method 1 described above.

  In this production method, various adhesives can be used, but it is preferable to use a material similar to the glove base or a material having a similar polarity value. Also, a resin solution such as latex or synthetic resin dispersion can be used like an adhesive, and once formed into a resin, the glove base is again dipped into these solutions, and after flocking, it can be solidified. .

  In addition, about the adhesives etc. which are used in manufacturing method 2, when an appropriate antibacterial agent and fungicide are mixed therewith, it is possible to suppress the growth and propagation of microorganisms and fungi inside the glove and prevent malodor and coloring. This is preferable. Examples of antibacterial or antifungal agents used for such purposes include silver, zeolite, zinc, copper and other inorganic, imidazole, phenol, bromine and nitrogen antibacterial or antifungal agents. An agent etc. can be mentioned.

  In both of the above production methods, as a method of depositing the treated short fiber on the glove base, a conventionally known method, for example, putting the treated short fiber into a sieve and applying vibration to the sieve, a semi-gelled or uncrosslinked glove Use a blower or a blower, connect a tank filled with treated short fibers to the blower suction port, suck the pile, and let the treated short fibers blown from the blower blowout port be in a semi-gel state or uncrosslinked state And a method of spraying the treated short fibers sucked with a blower on a semi-gelled or uncrosslinked glove base while letting the wind out with a cyclone. It can be applied by a flocking treatment, for example, a method of combining electrostatic flocking using electrodes. In the present invention, the short fibers are preferably subjected to electrostatic flocking treatment.

  Furthermore, in the moisturizing glove of the present invention, it is desirable that all of the short fibers attached to the inner surface of the glove base be treated short fibers, but the treated short fibers and the short fibers not treated with the moisturizing component ( Untreated short fibers) may be mixed and used. The mixing ratio of the treated short fiber and the untreated short fiber is not particularly limited, but the ratio of the treated short fiber to the untreated short fiber is preferably in the range of 100: 0 to 10:90. If the treated short fiber is less than 10% of the whole short fiber, the moisturizing effect may not be exhibited, which is not preferable. Moreover, the amount of short fibers deposited is about 1 to 20 g for a pair of gloves (both left and right), and more preferably in the range of 5 to 10 g.

  After the treated short fiber is attached to the glove base and solidified, the glove base is inverted and peeled from the hand mold to obtain a moisturizing glove whose inner surface is attached with the treated short fiber.

  The moisturizing glove of the present invention thus obtained can moisturize the hand and prevent rough skin of the user's hand, etc., due to its excellent moisturizing effect, and is flexible to the glove. A feeling of use can be imparted.
