Description

  The present invention relates to a glove having a laminated structure including at least one porous layer and a non-porous layer each made of rubber or resin, and a method for producing the glove.

Protect human hand skin, prevent food poisoning and infectious diseases, etc. in various scenes such as general households, factories, and medical sites, or handle objects (semiconductors, precision equipment, etc.) from sebum on the hand skin In order to protect it, gloves which are formed integrally with a rubber or resin film as a whole are widely used.
The glove is generally manufactured by a so-called dipping method.

For example, when manufacturing a glove that is integrally formed of a rubber film as a whole, first, a liquid latex composition in which various additives such as a vulcanizing agent are blended with a rubber latex to obtain an unvulcanized or pre-cured state. Prepare the product. Also, for example, a ceramic mold corresponding to the three-dimensional shape of the glove is prepared, and the surface thereof is treated with a coagulant (mainly calcium sulfate aqueous solution).
Next, the latex composition is adhered to the surface of the mold by immersing the mold in the latex composition for a predetermined time and then pulling it up.

The whole mold is heated to dry the latex composition and vulcanize the rubber, or once dried and heated together with the mold to vulcanize the rubber and then demold, so that the whole A glove formed integrally with the film is manufactured.
In addition, a glove that is integrally formed of a resin film as a whole is a latex composition prepared by blending various additives in a resin emulsion instead of the latex composition containing the rubber latex (strictly speaking, latex However, for the sake of convenience, it can be produced in the same manner as described above except that it is used in this manner in accordance with those containing rubber latex.

The glove is required to have excellent workability. It is an important performance of the glove made of the rubber or resin film to be thin and excellent in flexibility and suitable for work with fine fingertips, that is, excellent workability.
The glove may be required to have excellent heat insulation. However, flexibility, workability, and heat insulation are contradictory properties, and as the thickness of the film is increased to increase heat insulation, the flexibility decreases and the fingertip sensation becomes dull. There is a problem of lowering.

As one means for solving such a problem, it is conceivable to form the glove in a porous structure made of rubber or resin and enclosing a large number of bubble cells in the layer.
The layer having the porous structure, that is, the porous layer, for example, as described in Patent Document 1 and the like, the latex composition containing the rubber or resin is agitated or blown with air to foam, The foamed latex composition can be formed by using it in the dipping method in place of a normal non-foamed latex composition.

Although the porous layer is similarly made of rubber or resin, it is superior in heat insulation and flexibility as compared with a non-porous layer that does not enclose bubble cells.
However, since the porous layer has low strength, it does not form a glove alone, but is laminated with a layer (support layer) for maintaining the strength of the glove, such as a fiber glove base described in Patent Document 1, for example. Generally, a laminated structure is used.

JP 2011-1662 A

However, in the conventional gloves having such a laminated structure, since the thickness of the support layer is particularly large, the flexibility is lowered and it is difficult to ensure good workability.
An object of the present invention is to provide a novel glove having high flexibility, good workability, and high heat insulation, and a method for manufacturing the same.

In order to solve the above-mentioned problems, the inventor laminated a porous layer made of rubber or resin with a thin non-porous layer that is also made of rubber or resin and does not enclose bubble cells. Then, it was examined that the non-porous layer functions as a support layer for maintaining the strength.
As a result, the range of the total thickness of the laminate of the porous layer and the non-porous layer, the ratio of the thickness of the porous layer in the total thickness, and the bubble content of the porous layer, respectively, It has been found that this is an important factor for simultaneously achieving high flexibility, good workability, and high thermal insulation.

  Therefore, as a result of further examination of these ranges, the total thickness of the laminate is 0.4 mm or more and 0.6 mm or less, and the proportion of the thickness of the porous layer in the total thickness is 30% or more and 60%. Hereinafter, it is found that if the bubble content of the porous layer is 20% or more and 60% or less, a novel glove having high flexibility, good workability, and high heat insulation can be obtained. It came to complete.

That is, the present invention is a glove comprising a laminate of at least one porous layer and a non-porous layer each consisting entirely of a rubber or resin film , wherein the porous layer has a viscosity after foaming. It is formed by a dipping method using a foamed latex composition of 150 mPa · s or more and 700 mPa · s or less, and the total thickness of the laminate is 0.4 mm or more and 0.6 mm or less, and the porous The proportion of the thickness of the porous layer in the total thickness is 30% or more and 60% or less, and the bubble content of the porous layer is 20% or more and 60% or less. is there.
In consideration of further improving the flexibility, workability, and heat insulation, the ratio of the thickness of the porous layer to the total thickness of the laminate is 50% or more even within the above range. preferable.

This invention is a manufacturing method for manufacturing the glove of the said invention, Comprising: The immersion method was used using the latex composition which foamed the said porous layer with the viscosity of 150 mPa * s or more and 700 mPa * s or less. It is characterized by forming by.
According to the present invention, the foam stability can be ensured by setting the viscosity of the foamed latex composition to 150 mPa · s or more. Therefore, the bubble content rate of the porous layer can be increased even within the above range, and the heat insulating property of the gloves can be further improved.
On the other hand, when the viscosity is 700 mPa · s or less, good fluidity of the foamed latex composition can be ensured. Therefore, while maintaining the bubble content of the porous layer within the above range, the total thickness of the laminate of the porous layer and the non-porous layer is reduced within the above range to further improve workability. It becomes possible to do.

  ADVANTAGE OF THE INVENTION According to this invention, the novel glove which has high softness | flexibility, favorable workability | operativity, and high heat insulation, and its manufacturing method can be provided.

The glove of the present invention is formed entirely by a laminate of at least one porous layer and non-porous layer made of rubber or resin. The specific layer configuration of the laminate is not particularly limited except that it includes at least one porous layer and a non-porous layer as described above, and can be arbitrarily configured.
For example, the laminate includes a two-layer structure in which a porous layer and a non-porous layer are laminated one by one, or three or more layers including at least one of the porous layer and the non-porous layer. It can be a multilayer structure. The order of stacking the porous layer and the non-porous layer can be arbitrarily set. For example, in the case of the laminate having the two-layer structure, the porous layer may be inside or outside the glove.

The glove of the present invention comprising such a laminate has a total thickness of the laminate of 0.4 mm or more and 0.6 mm or less, and the proportion of the thickness of the porous layer in the total thickness is 30% or more, In addition to being 60% or less, the bubble content of the porous layer needs to be 20% or more and 60% or less.
The reason why the total thickness of the laminate is limited to 0.4 mm or more and 0.6 mm or less is as follows.

  That is, if the total thickness is less than the above range, the laminate is too thin, and in order to impart sufficient strength to the glove made of the laminate, the thickness of the porous layer and the bubble content must be reduced. For this reason, the heat insulating properties of the gloves are lowered, and accordingly, workability at a high temperature is lowered. On the other hand, when the total thickness exceeds the above range, the laminate is too thick, and the flexibility and workability of the glove made of the laminate are reduced.

On the other hand, by providing the total thickness of the laminate within the above range, the glove made of the laminate is provided with sufficient strength and high heat insulation properties, while providing high flexibility and good workability. can do.
Further, the ratio of the thickness of the porous layer in the total thickness is limited to 30% or more, and if it is less than the above range, the effect described above by providing the porous layer cannot be obtained, and the gloves This is because the heat insulation property and workability of the material deteriorate.

On the other hand, by making the ratio of the thickness of the porous layer in the total thickness within the above range, the glove can be provided with high flexibility, good workability, and high heat insulation. In particular, the heat insulation, flexibility, and workability of the gloves can be further improved by setting the ratio to 50% or more even within the above range.
However, if the ratio of the thickness of the porous layer in the total thickness is too high, the thickness of the non-porous layer becomes relatively small, and the function of the non-porous layer as a support layer Since it cannot be obtained sufficiently, the gloves cannot be provided with sufficient strength. In addition, the flexibility and workability of gloves are reduced. Therefore, the ratio of the thickness of the porous layer in the total thickness is limited to 60% or less even within the above range.

The thickness of the porous layer is the thickness of the one porous layer when the laminate includes only one porous layer, and when the laminate includes two or more porous layers, The total thickness of two or more porous layers.
The air bubble content of the porous layer is limited to 20% or more. If the porous layer is less than the above range, the heat insulating property and flexibility of the porous layer itself are insufficient. This is because the heat insulation and workability of the gloves are reduced.

On the other hand, by making the bubble content rate of a porous layer into the said range, high flexibility, favorable workability | operativity, and high heat insulation can be provided to a glove. When a laminated body contains two or more porous layers, the bubble content rate of all the porous layers must be in the said range.
However, when the bubble content is too high, the bubble cells contained in the porous layer are easily crushed by external force or the like, and it becomes difficult to stably maintain the porous layer. Workability is reduced. Therefore, the bubble content is limited to 60% or less even within the above range.

In the present invention, the total thickness of the laminate, the ratio of the thickness of the porous layer in the total thickness, and the bubble content of the porous layer are expressed by values measured by the following methods, respectively. . All measurements shall be carried out in an environment of 23 ± 1 ° C.
<Thickness>
A specimen is cut from the glove containing the porous membrane, and a micrograph of the cross section is taken using a digital microscope. And the thickness of the porous layer and the non-porous layer is measured from the photographed micrograph, and from the result, the total thickness of the porous layer and the non-porous layer is determined as the total thickness ( mm). Further, the ratio (%) of the thickness of the porous layer to the total thickness is determined from the total thickness and the thickness of the porous layer.

<Bubble content>
A specimen having a predetermined area is cut out from the glove including the porous membrane, and a micrograph of the cross section is taken using a digital microscope. Then, the thickness of the porous layer and the non-porous layer is measured from the photographed micrograph, and the volume of the porous layer and the non-porous layer is determined from the thickness and the area of the test piece. The mass of the non-porous layer is determined from the volume of the non-porous layer and the true specific gravity of the material forming the non-porous layer.

Next, the mass of the test piece is measured using an electronic balance, and the mass of the porous layer is obtained by subtracting the mass of the non-porous layer obtained previously from the mass. Then, the apparent specific gravity of the porous layer is calculated from the volume and the mass, and the bubble content (%) of the porous layer is calculated from the apparent specific gravity and the true specific gravity of the material forming the porous layer. calculate.
The glove of the present invention is preferably formed by a dipping method as in the prior art.

Specifically, for example, a mold corresponding to a three-dimensional shape of a glove is prepared, and after the surface of the mold is treated with a coagulant as usual, each non-porous layer and each latex composition that becomes the basis of the porous layer are prepared. Each latex composition is adhered to the surface of the mold in a laminated state by repeating the operation of sequentially pulling up after being dipped in a product for a certain period of time.

As a result, while maintaining good adhesion and integrity between each layer, the latex composition constituting each layer is prevented from mixing, and the internal structure of the porous layer and the non-porous layer in particular is clearly defined. The functions of each layer can be expressed individually and satisfactorily.

Therefore, the bubble content rate of the porous layer can be increased even within the above range, and the heat insulating property of the gloves can be further improved.

On the other hand, when the viscosity is 700 mPa · s or less, good fluidity of the foamed latex composition can be ensured. Therefore, while maintaining the bubble content of the porous layer within the above range, the total thickness of the laminate of the porous layer and the non-porous layer is reduced within the above range to further improve workability. It becomes possible to do.
In consideration of further improving these effects, the viscosity is preferably 200 mPa · s or more, more preferably 360 mPa · s or more, even within the above range, and 600 mPa · s or less, particularly 450 mPa · s or less. Is preferred.
