Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a glove that can be used on both sides and has an anti-slip protrusion on the screen coated with rubber or resin such as vinyl chloride.

[Prior Art and its Problems] Knitted gloves and knitted gloves whose surfaces are entirely coated with a resin such as rubber or vinyl chloride are known. These gloves have the disadvantage of poor breathability due to the nature of the covering material, making the hands stuffy.
In addition, with gloves coated entirely with resin, when you try to bend your fingers, the back of your hand tends to stretch.
Also, the side of the back of the hand among the sides of the fingers also tries to stretch. On the other hand, the palm side tends to wrinkle and bend, creating resistance when bending the fingers.The resin film is formed over the entire surface of the glove base, making it inflexible and stiff, making work difficult. There are some difficult issues.

As a solution to this problem, Jikosho 7-
No. 16478 discloses a glove in which both sides of the fingers are covered with rubber. According to this glove, the above problems can be solved to some extent.

However, the following problem arises. In other words, rubber-covered gloves do not allow air or water to pass through, so when handling wet objects, water can get between the gloves and the object and cause slipping, making them unsuitable as work gloves. . Further, it is preferable that work gloves be flexible, but in the case of the above-mentioned gloves, even though the fingers can be easily bent compared to conventional fully covered gloves, this is still not sufficient.

[Object of the Invention] Therefore, the object of the present invention is to provide resin-uncoated parts on both sides of the fingers of a glove coated with resin on both sides, so that both sides of the glove can be used, and resin is coated on both sides. The anti-slip protrusion solves the lack of flexibility and poor breathability caused by covering the glove, and also makes the surface of the glove permeable to prevent it from slipping even when it is wet with water. The present invention provides gloves that can be used on both sides.

[Configuration of the Invention] The configuration of the present invention taken to achieve the above object will be explained with reference to the drawings. That is, in the present invention, a permeable resin film is provided on a permeable fabric glove base material, and a resin film is formed on the surface of the resin film when the resin liquid adhering to the glove base material is in a sol state. It has highly protruding irregular mesh-like anti-slip projections formed by the bursting of countless bubbles in the liquid, and countless irregular mesh-like recesses formed by the formation of the anti-slip projections. The countless recesses include a mixture of permeable and non-permeable recesses, and vents without a resin film are located between the index finger and the middle finger, between the middle finger and the ring finger, and between the ring finger and the ring finger. These gloves can be used on both sides and have a non-slip protrusion between the little fingers.

The glove base material has permeability and can be woven or knitted fabrics such as cotton, synthetic fibers, and cotton. Examples of means for providing the resin film on the glove base material include a method of immersing the glove in a resin liquid, a method of applying or spraying the resin liquid, and the like.

As the resin, natural resin such as natural rubber, synthetic resin such as vinyl chloride resin, vinyl acetate resin, polyurethane resin, or synthetic rubber is used.

On the surface of the resin film provided on the glove base material,
a highly protruding irregular mesh-like anti-slip protrusion formed by bursting of numerous bubbles in the resin liquid when the resin film attached to the glove base material is in a sol state;
Numerous irregular mesh-like recesses are provided by forming the anti-slip protrusions.

The mesh-like anti-slip protrusions are not constant and are formed irregularly depending on the size of the bubbles, their density, etc. For example, it has a leaf vein shape, a loofah fiber shape, an irregular honeycomb shape, or a capillary shape distributed in the tissue.

The recess is formed, for example, in the shape of a crater by the bursting of bubbles, and similarly to the anti-slip protrusion, the size and depth depend on the size of the bubble and its density, as will be explained in later examples. Similarly, the shape is not constant.

Some of the recesses are permeable and allow gas or liquid to pass therethrough, while others are not permeable, and although these recesses are mixed in the resin film, the resin film as a whole has permeability.

That is, gloves have permeability when the resin film is not cross-linked between adjacent threads of the glove base material and the gaps between the threads form through holes, and when the cross-linked resin film is destroyed. However, gloves whose surface is coated with a resin film do not have permeability.

In addition, in the method for manufacturing the glove described above, the covering member is brought into close contact between the fingers of the glove base so as to straddle the covering member elastically erected above the resin liquid level, and the covering member and the glove base are brought into close contact with each other. The gloves are pressed down and immersed in the resin liquid while keeping the covering member and the glove base in close contact with each other, and then pulled up from the resin liquid surface while keeping the covering member and the glove base in close contact with each other.Then, the covering member is separated from the glove base so that there is no resin film between the fingers. One example is a method of forming a ventilation section.

In addition, the fingers of a breathable glove base are brought into close contact with each other to prevent resin from adhering between the fingers, and the glove base is immersed in a resin film while the fingers are kept in close contact with each other. It is also possible to form a ventilation section without a resin film between the fingers.

[Example] The present invention will be described in more detail based on an example shown in the drawings.

1 is a perspective view of the glove, FIG. 2 is an enlarged view of section A in FIG. 1, and FIG. 3 is an end view of FIG. 2.

Reference numeral 1 denotes a glove base material made of cloth, and a resin film 2 is provided on both sides of the palm side and the back of the hand. Glove base material 1
is woven from cotton yarn and has breathability and moisture absorption properties. Among the fingers of the glove, between the index finger 12 and the middle finger 13, between the middle finger 13 and the ring finger 14, and between the ring finger 14 and the little finger 1
5, a ventilation section 30 without the resin film 2 is formed extending from the base of each finger section to just before the first joint. Therefore, the first joint is covered with the resin film 2, and although the bending and extension of the fingers is limited to some extent, the resin film 2 protects the fingertips. Note that the ventilation portion 30 may also be formed on the thumb 11, or may extend over the entire length of each finger.

The resin film 2 has highly protruding irregular mesh-like anti-slip protrusions 3 formed by the bursting of numerous bubbles in the resin liquid when the resin liquid adhered to the glove base material 1 is in a sol state. , numerous irregular mesh-shaped recesses 5 formed by the formation of the anti-slip projections 3;
6 is provided.

The anti-slip protrusion 3 has elasticity, gradually becomes sharper toward the tip, and its height is not uniform.

The recesses 5 and 6 are not uniform in size, and there are recesses 5 whose bottoms reach the surface of the glove base 1 and recesses 6 whose bottoms do not reach the surface. Even among the recesses 5 that have been reached, there are a mixture of those that have the transmission holes 20 and those that do not.

The anti-slip protrusion 3 and the recesses 5 and 6 are formed by bursting bubbles when the resin liquid is in a sol state, and then further heat treatment. The formation process will be explained with reference to FIG.

The glove base material 1 is immersed in a foamed resin liquid (latex, plastisol, organosol, etc.) containing a large amount of air bubbles with a particle size of about 0.2 to 2.0 mm, so that the resin liquid adheres to its surface. (See Figure 4a). Then, the glove base material 1 is pulled up from the resin liquid and ruptured in a sol state. The particle size of air bubbles in the resin liquid is 0.2 to 2.0 mm.
There are various sizes between them. When the large bubble 8 bursts, a crater-shaped recess 5 that reaches the glove base material 1 is formed at the bursting part. When the small air bubbles 7 burst, a crater-shaped recess 6 is formed in which the burst portion does not reach the glove base 1 (see FIG. 4c).

In addition, the bubbles are burst one after another in a sol state.
Therefore, due to the cohesive force of the ruptured liquid phase, the anti-slip protrusion 3 is wide at the point where it rises from the glove base material 1, and becomes narrower and sharper toward the tip (Fig. 4b, Fig. 4). (see figure c).

Although the mechanism by which the above-mentioned anti-slip protrusion 3 is formed is not necessarily clear, it is thought to be as follows. That is, part of the liquid phase (diluent, plasticizer, etc.) containing the diluent of the resin liquid permeates into the glove base material 1, making it more likely to rupture and increasing the viscosity and yield value. After bursting, the resin liquid whose viscosity and yield value have increased forms a continuous protrusion along the contour of the bubble due to cohesive force. Furthermore, it is thought that the diluent and the like are vaporized and released by heating, and are then heat-treated in a contracted state. In this way, the resin liquid after rupture is
In balance with the decrease in the liquid phase, the viscosity increases, and at the same time, the yield value also increases, resulting in poor fluidity, and as a result, the anti-slip protrusion 3 becomes difficult to collapse and forms an acute angle.

In order to burst the bubbles, the viscosity of the resin liquid should be 500 CP or less, preferably 300 CP or less, which is easy to burst. In addition, to break the air bubbles, place the gloves with air bubbles attached under reduced pressure at 4 m/sec.
The following methods include applying wind pressure, rapidly heating at 100°C to 200°C to expand and break the bubbles, and applying vibration or shock to the glove with bubbles attached.

Further, it is preferable to apply the resin liquid slightly thinly so that the finger can be easily bent.

FIG. 5 is an end view of essential parts of another embodiment.

In order to increase the protrusion of the anti-slip protrusion 3, an appropriate amount of coarse resin or other coarse particles 4 is added to the resin liquid to an extent that does not cause sudden sedimentation when the resin liquid is in a foamed state. When the resin liquid containing the coarse particles 4 is applied to the glove base material 1, the adsorption force and cohesive force of the liquid on the scattered coarse particles 4 act simultaneously, and the synergistic effect causes the protrusions to become high and sharply slippery. A stop protrusion 3 can be formed. In the case of this embodiment, the coarse particles 4 may be located at the tips of the anti-slip protrusions 3.

FIG. 6 shows a first method of manufacturing a glove that can be used on both sides.

When forming the resin film 2 on both sides of the glove base 1, the glove base 1 is placed on a glove mold 4 with a slight gap between the fingers, and immersed in the resin solution with the fingers in close contact with each other.

7 to 10 show the second manufacturing method.

Reference numeral 50 denotes a coating device, which has guide shafts 5 on both sides of a base 55.
1,51a are installed upright, and the guide shafts 51,51a
Coil springs 52, 52a are loosely attached to the coil springs 52, 52a. An elongated covering member 53 having a triangular cross section is placed on top of the coil springs 52, 52a, and guide shafts 51, 51a are fitted into through holes formed at both ends of the covering member 53. Therefore, the covering member 53 moves up and down along the guide shafts 51, 51a. These three coating devices 50 are placed adjacently, and the coating member 5
3 is placed in the container 60 so that it is not below the resin liquid level. Then, the glove base 1 is placed over a required number of glove molds 70 having finger portions formed at intervals corresponding to the intervals of the covering members 53.

The covering member 53 is then brought into close contact between the finger parts 12, 13, 14, and 15 so as to straddle the covering member 53, so that resin does not adhere between the finger parts. Thereafter, the covering member 53 and the glove base material 1 are pressed down while being kept in close contact with each other and immersed in the resin liquid 80 to adhere the resin liquid. Thereafter, the covering member 53 and the glove base 1 are pulled up from the resin liquid surface while being kept in close contact with each other, and the covering member 53 and the glove base 1 are separated, and the glove has the ventilation portion 30 formed without the resin film 2 between the fingers.

A glove base material 1 made of cotton Merisses is immersed in the resin solution, and after the resin solution has sufficiently adhered to the glove base material 1, it is lifted out of the resin solution and placed in a sealed vacuum container, and the pressure is reduced to 400 mm/Hg using a vacuum pump. to burst the air bubbles, then heat at about 185°C for 20 minutes to obtain gloves.

[Effect of the invention] The present invention has the following effects.

(b) On the surface of the resin film provided on the cloth glove base material, when the resin liquid adhering to the glove base material is in a sol state, numerous bubbles are formed in the resin liquid by bursting. It also has a raised irregular mesh-like anti-slip protrusion.

Therefore, the anti-slip function can be achieved even against external forces from different directions.

(b) The glove base material is made of permeable cloth, and the resin membrane is permeable. Further, the anti-slip protrusions are formed by the bursting of bubbles when the resin liquid is in a sol state, and stand out high.

Therefore, even if the object to be handled is wet with water, oil, etc., the protrusions can break through the film of water, oil, etc. Water, oil, etc. that are excluded at this time can permeate the resin film and escape to the glove base material side. Therefore, there is no film of water or oil between the resin film and the object to be handled, and the protrusions can adhere directly to the object to be handled without slipping due to the film of water, oil, etc. can perform a function.

(c) Among the recesses, the recesses that are not permeable have a suction cup shape, and interact with the projections to provide a sufficient anti-slip effect.

(d) The resin film is provided with numerous mesh-like recesses formed by the formation of anti-slip protrusions. The resin portion is reduced by the amount of the recessed portion, and the recessed portion serves as a resin release portion during bending. The glove is therefore extremely flexible and has no resistance to bending.

(e) The resin film has permeability. Therefore, they do not get stuffy even when worn, making them suitable as work gloves.

(f) The glove base material is made of permeable material. For this reason, part of the liquid phase containing the diluent of the resin liquid penetrates into the glove base material, and the liquid phase of the resin decreases, making it easier to burst.The viscosity of the resin liquid after bursting increases, and the resin Due to the cohesive force of the liquid, the bubbles can be raised high along the contour to form thick non-slip protrusions at the base. Also, since the base is thick, it has sufficient strength against wear.
