Description

gloves

The present invention relates to a glove comprising a porous membrane of rubber or resin.

Protects human skin in various situations such as general household, factory, medical field, or sports, prevents food poisoning and infectious diseases, etc., or handles objects (semiconductors, precision instruments etc.) to be handled Various gloves are widely used in order to protect from etc.
In particular, gloves integrally formed by a film of rubber or resin as a whole are widely used because they are thin and suitable for fine work of a finger tip or the like.

The gloves are generally manufactured by the so-called immersion method.
For example, in the case of producing a glove integrally formed of a film of rubber as a whole, first, various additives such as a vulcanizing agent are mixed with a latex of rubber to prepare an immersion liquid in an unvulcanized or prevulcanized state. . Further, for example, a pottery mold corresponding to the three-dimensional shape of the glove is prepared, and the surface is treated with a coagulant (mainly, an aqueous solution of calcium nitrate).

Then, the mold is immersed in the immersion liquid for a certain period of time and then pulled up to cause the immersion liquid to adhere to the surface of the mold.
The whole mold is heated to dry the immersion liquid and cure the rubber, or after drying once, the whole mold is heated to vulcanize the rubber and then demolded to obtain a film of the whole rubber. An integrally formed glove is produced.

In addition, the glove integrally formed of a resin film as a whole is the same as the above except using an immersion liquid prepared by blending various additives into an emulsion of resin instead of the immersion liquid containing rubber latex. Can be manufactured.
However, since a continuous film of rubber or resin does not have moisture permeability or hygroscopicity, there is a problem that when the glove is worn for a long time, so-called "steaming feeling" is generated in which the hands become steamy or sticky due to sweat. .

A glove is a laminated structure of two or more layers mainly including a porous film having a continuous pore structure, particularly a laminated structure in which an innermost layer in contact with a hand is a porous film, the moisture generated from the hand is There is a method of reducing the feeling of stuffiness by absorbing or releasing it to the outside by the air permeability of the porous membrane.
In the immersion method, a film of rubber or resin to be formed can be made into a porous film mainly having a continuous pore structure by foaming the immersion liquid.

For example, in Patent Document 1, the porous membrane is laminated with a fibrous glove to impart breathability to the glove.

JP, 2011-1662, A

However, according to the inventor's investigation, the conventional porous membrane is insufficient in hygroscopicity or air permeability because the total amount of bubbles contained therein (total bubble volume) is generally small.
For example, in the case of a porous film laminated with fibrous gloves as in the porous film described in Patent Document 1 etc., the size and number of pores are naturally limited from the viewpoint of preventing the intrusion of water etc. from the outside. , Its breathability is not enough.

Therefore, under the present circumstances, none of the conventional gloves provided with the porous membrane can fully satisfy the reduction of the feeling of stuffiness expected by the user.
An object of the present invention is to provide a glove with reduced feeling of stuffiness.

In order to solve the above-mentioned subject, the inventor examined earnestly the relation between the structure of a porous membrane, and the hygroscopicity of a glove provided with a porous membrane, and a feeling of stuffiness.
As a result, in the porous membrane, the bubble content as an index of the bubble total volume is 20% by volume or more and 60% by volume or less, the average cell diameter indicating the size of individual bubbles is 150 μm or less, and the ratio of the continuous pore structure The porous film has a continuous pore structure by defining the cell communication ratio of 30% to 80%, and the glove has a sense of stuffiness as it has a large bubble volume and a large hygroscopicity. It has been found that it can be significantly reduced, and the present invention has been completed.

That is, the present invention is a glove including a porous film of rubber or resin, and the porous film has a bubble content of 20% by volume or more and 60% by volume or less, an average cell diameter of 150 μm or less, and The communication rate is 30% or more and 80% or less.
In the present invention, the bubble content ratio indicating the ratio of the total volume of the bubbles contained per unit volume of the porous membrane is limited to the above-mentioned range for the following reason.

That is, if the air bubble content rate is less than 20% by volume, the total air bubble volume in the porous membrane is insufficient, the hygroscopicity becomes insufficient, and the effect of reducing the feeling of stuffiness of the glove can not be obtained.
On the other hand, when the air bubble content rate exceeds 60% by volume, the strength of the porous membrane and hence the glove is lowered, and it becomes easy to be broken at the time of use.
On the other hand, when the cell content of the porous membrane is in the range of 20% by volume to 60% by volume, the total volume of the cells of the porous membrane is given while giving appropriate strength to the porous membrane and gloves. It is possible to make it as large as possible, to improve the hygroscopicity as much as possible, and to significantly reduce the feeling of stuffy gloves.

In addition, in consideration of further improving the effect and further reducing the feeling of stuffiness, the bubble content is preferably 35% by volume or more even in the above range.
Moreover, it is based on the following reason that an average bubble diameter is limited to the said range.
That is, when the average cell diameter exceeds 150 μm, the surface area inside the individual cells becomes small even with the same amount of cells, so that the hygroscopicity is reduced to cause a problem that moisture can not be absorbed efficiently.

On the other hand, if the average cell diameter of the porous membrane is in the range of 150 μm or less, the surface area inside the cells can be increased, so the hygroscopicity of the porous membrane can be improved and moisture can be absorbed more efficiently. In this way, it is possible to significantly reduce the feeling of stuffy gloves.
In addition, in consideration of further improving the effect and further reducing the stuffiness of the glove, the average cell diameter is preferably 70 μm or less even in the above range.

Furthermore, the reason why the cell communication ratio indicating the ratio of the continuous pore structure is limited to the above-mentioned range is as follows.
That is, if the air bubble communication rate is less than 30%, the proportion of the independent pore structure that does not contribute to moisture absorption is large, and the hygroscopicity of the porous film becomes insufficient, and the effect of reducing the feeling of stuffiness of the glove can not be obtained.
On the other hand, if the air bubble communication rate of the porous membrane is in the range of 30% or more, the hygroscopicity of the porous membrane can be improved, moisture can be absorbed more efficiently, and the glove has a sense of stuffiness. It will be possible to reduce significantly.

However, if the rate of communication is too high, the strength of the porous membrane, and hence the glove, is reduced, and it becomes easy to tear when used. Therefore, the communication rate is limited to 80% or less even in the above range.
In addition, in consideration of further improving the effect and further reducing the stuffiness of the glove, the communication rate is preferably 50% or more even in the above range.

ADVANTAGE OF THE INVENTION According to this invention, the glove excellent in the reduction effect of a feeling of stuffiness conventionally can be provided.

The present invention is a glove including a porous membrane of rubber or resin, and the porous membrane has a bubble content of 20% by volume or more and 60% by volume or less, an average cell diameter of 150 μm or less, and a cell communication ratio Is 30% or more and 80% or less.
The bubble content of the porous membrane is limited to the above range for the following reasons.
That is, if the air bubble content rate is less than 20% by volume, the total air bubble volume in the porous membrane is insufficient, the hygroscopicity becomes insufficient, and the effect of reducing the feeling of stuffiness of the glove can not be obtained.

On the other hand, when the air bubble content rate exceeds 60% by volume, the strength of the porous membrane and hence the glove is lowered, and it becomes easy to be broken at the time of use.
On the other hand, when the cell content of the porous membrane is in the range of 20% by volume to 60% by volume, the total volume of the cells of the porous membrane is given while giving appropriate strength to the porous membrane and gloves. It is possible to make it as large as possible, to improve the hygroscopicity as much as possible, and to significantly reduce the feeling of stuffy gloves.

In addition, in consideration of securing a sufficient hygroscopicity by sufficiently enlarging the bubble total volume of the porous membrane, the average bubble diameter is preferably 10 μm or more, particularly 50 μm or more even in the above range.
Furthermore, the reason why the cell communication ratio indicating the ratio of the continuous pore structure is limited to the above-mentioned range is as follows.

That is, if the air bubble communication rate is less than 30%, the proportion of the independent pore structure that does not contribute to moisture absorption is large, and the hygroscopicity of the porous film becomes insufficient, and the effect of reducing the feeling of stuffiness of the glove can not be obtained.
On the other hand, if the air bubble communication rate of the porous membrane is in the range of 30% or more, the hygroscopicity of the porous membrane can be improved, moisture can be absorbed more efficiently, and the glove has a sense of stuffiness. It will be possible to reduce significantly.
