Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a working rubber glove, and more particularly, to a rubber glove excellent in usability, which has a non-slip function on its surface and can grip tableware and the like without slipping off in water work in a kitchen or the like. It relates to the manufacturing method.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are known support gloves and non-support gloves as work gloves made of vinyl chloride or natural rubber.
As described in Patent Document 1, for example, a support type glove is prepared by immersing a glove mold covered with a fiber glove base material in a vinyl chloride paste or a natural rubber latex solution to apply a vinyl chloride or natural It is obtained by forming a film of a rubber glove body and removing the glove body from the glove mold as it is.
[0003]
On the other hand, as described in Patent Document 2, for example, a non-support type glove is formed by immersing a glove mold in a vinyl chloride paste to form a vinyl chloride glove body on the glove mold surface, and forming an outer surface thereof. After the short hair layer is formed, the glove body is turned over and released from the glove mold, thereby obtaining a product having the short hair layer on the back surface.

[Problems to be solved by the invention]
By the way, when the surface of this type of work glove has a non-slip function, in the case of a support type glove, since the outer surface side of the glove body formed on the glove type surface becomes the product surface as it is, the outer surface side of the glove body Can be subjected to various types of non-slip processing.
However, in the case of non-support type gloves, the inner surface of the glove body formed on the glove type surface is the product surface. By providing an uneven pattern and transferring the unevenness to the inner surface of the glove body to be formed into a film, the glove body surface after release has a non-slip function.
[0006]
However, the unevenness transferred to the surface of the rubber glove by the above-described method does not provide a sufficient anti-slip effect. For example, when used for water work in a kitchen or the like, there is a possibility that the caught tableware or the like may slip off. Was.
In order to solve such a problem, Patent Literature 2 describes a method of forming a glove body after forming a non-slip layer containing fine powder or the like on a glove-shaped surface. When such a method is applied to gloves made of natural rubber, there is a problem that the fine powder or the like is not completely adhered, and the fine powder or the like easily falls off during or after the production.
[0007]
The present invention has been made in view of such a conventional situation, and an object thereof is to provide a non-support type working rubber glove having a sufficient anti-slip effect on the surface of a rubber glove body, and a glove for the same. It is to provide a manufacturing method.
[0008]
[Means for Solving the Problems]
In view of the above-mentioned conventional circumstances, the inventors of the present application have conducted intensive studies, and as a result, in the process of producing a non-support type working rubber glove, a mixed layer in which a natural rubber acrylic copolymer and non-slip particles were mixed was formed. The present invention has been found to be extremely useful for fixing a large number of non-slip particles on the surface of a glove body made of natural rubber latex, and has completed the present invention.
[0009]
That is, the non-support type working rubber glove according to the present invention is embossed by transferring an uneven pattern of the glove-type surface to the surface of the glove body made of natural rubber latex, and integrated with the glove body surface. A non-slip portion comprising a large number of non-slip particles fixed to the surface is formed.
[0010]
According to such a configuration, a non-slip function by embossing and a non-slip function by a large number of non-slip particles are provided, and by these synergistic effects, a non-slip effect similar to a feeling of grasping an object with bare hands is exerted. be able to.
[0011]
It is preferable that the non-slip particles are integrally fixed to the surface of the glove body by a natural rubber acrylic copolymer layer.
In the case of such a configuration, the natural rubber acrylic copolymer layer is integrated with the surface of the glove body made of natural rubber latex, and many anti-slip particles are firmly adhered to the surface of the natural rubber latex glove body. be able to.
[0012]
In the manufacturing process of the non-support type rubber glove, the natural rubber acrylic copolymer layer is formed on the surface of the glove mold before forming the glove body.
That is, after a natural rubber acrylic copolymer layer is formed on a glove-shaped surface, a glove body layer made of natural rubber latex is formed on the surface. When the natural rubber acrylic copolymer is formed on the inner surface of the glove body (the glove in the product). Mixed with the body surface) to gel (coagulate) the inner surface side of the glove body, whereby a large number of non-slip particles contained in the natural rubber acrylic copolymer layer are firmly adhered to the inner surface side of the glove body. It becomes fixed.
The natural rubber acrylic copolymer layer also contributes to giving the glove body a predetermined thickness.
[0013]
As the non-slip particles, it is also possible to use particles or glass particles of a synthetic resin such as acrylic or the like, and to prevent falling off during or after glove production, and to obtain the above-mentioned remarkable anti-slip effect. It is preferable to use rubber particles.
[0014]
Further, as described above, the rubber glove according to the present invention has a remarkable slip that approximates a feeling of grasping an object with bare hands due to a synergistic effect of the anti-slip function by embossing and the anti-slip function by a large number of anti-slip particles. Although an anti-slip effect can be obtained, in order to obtain such an anti-slip effect, it is preferable that the embossed pitch is 0.5 to 1 mm and the particle size of the anti-slip particles is 20 to 50 mesh. .
[0015]
Further, the rubber glove according to the present invention is a natural rubber acrylic copolymer containing a large number of non-slip particles after immersing a glove mold having an embossed concavo-convex pattern on the surface in a coagulant solution. The glove mold is immersed in a solution to adhere non-slip particles to the surface of the glove mold, and then the glove mold is immersed again in a coagulant solution to form the natural rubber acrylic copolymer containing the large number of non-slip particles. A mixed layer of a coagulant is formed, and the glove mold is further immersed in a natural rubber latex solution to form a glove body in which a non-slip portion formed of embossing and a large number of non-slip particles is formed on the inner surface, The glove body can be easily manufactured by a method characterized in that the glove body is inverted and released from the glove mold.
[0016]
Further, in the rubber glove according to the present invention, in the above method, after forming the glove body into a film, the glove mold is immersed in a natural rubber latex solution containing short hairs to form an outer surface of the glove body. By forming a short hair layer, and then including a step of turning over the glove body and releasing from the glove mold, it can be easily manufactured as a rubber glove having a short hair layer on the back surface. .
[0017]
