Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a glove having anti-slip protrusions on the surface and having a part without a resin layer on the upper part to improve air permeability, and a method for manufacturing the same.

[Prior art and its problems] A glove in which a foam layer is provided on the surface of the glove base material is described in Japanese Utility Model Publication No. 36-235. This glove is
A liquid containing a foaming agent is heated to foam the surface of a rubber glove base to form a hollow sphere, and the upper half of the hollow sphere is removed by cutting and polishing to form a hemispherical concave suction cup. be.

As can be seen from the lack of the expression "protrusions" here, the glove has numerous hemispherical recesses formed on its surface, and the ones formed between the hemispherical recesses are not protrusions but partitions forming suction cups. . Furthermore, since the glove base is made of rubber, it does not allow air or water to pass through. As a result, they are not suitable as work gloves because they can make your hands stuffy or slip when handling wet objects.

[Object of the invention] The present invention has flexibility and breathability, and
An object of the present invention is to provide a glove that has an anti-slip effect even when it is wet with water, and a method for manufacturing the same.

[Configuration of the Invention] The configuration of the present invention taken to achieve the above object will be explained with reference to the drawings.

The first invention is ventilation parts 10, 11, 12 that do not have a resin layer on the instep side.
A resin layer 2 is provided on the surface of the permeable cloth glove base 1 excluding the ventilation portions 10, 11, and 12, and a resin layer 2 is provided on the surface of the resin layer 2. When the resin liquid adhered to 1 is in a sol state, the non-slip protrusions 3 are formed by the bursting of countless bubbles in the resin liquid, and the non-slip protrusions 3 are raised irregularly and are formed by the non-slip protrusions. The glove is provided with countless recesses 5 and 6 in the form of an irregular network, and the countless recesses 5 and 6 are a mixture of permeable and non-permeable recesses.

The glove base material can be woven or knitted fabric such as cotton, synthetic fiber, or cotton. Examples of means for providing the resin layer on the glove base material include a method of dipping it 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 layer provided on the glove base material,
a highly protruding irregular mesh-like anti-slip protrusion formed by bursting of countless bubbles in the resin liquid when the resin liquid adhered 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. Further, there are two types of recesses: those that have permeability and can allow gas or liquid to pass therethrough, and those that do not have permeability, and these are mixed in the resin layer. Glove base materials in which the resin film is not cross-linked between adjacent threads and the gaps between the threads form through holes, and those in which the cross-linked resin film is destroyed, have permeability. However, gloves whose surface is coated with a resin film do not have permeability.

The second invention is to cover a glove type with a flat part on the back side with a permeable fabric glove base material, and to make the back parts face each other in close contact, and to hold a large amount of small air bubbles. In this method, the gloves are immersed in a resin liquid to adhere to the surface, then pulled up to burst small bubbles, and then heated and molded to have anti-slip protrusions on the surface.

To break air bubbles, place gloves with air bubbles attached under reduced pressure, apply wind pressure of 4 m/sec or more, rapidly heat the air at 100°C to 200°C to expand and break air bubbles, or remove air bubbles. One method is to apply vibration or shock to the gloves that have been attached.

[Example] The present invention will be described in more detail based on an example shown in the drawings. Figure 1 is a plan view from the instep side.
Fig. 2 is a partially enlarged plan view of the resin layer, and Fig. 3 is a partially enlarged plan view of the resin layer.
FIG.

1 is a glove base material made of cloth, and a resin layer 2 is provided on the upper part 10, a part 11 of each finger part following it, and a wrist part 12;
1. The wrist part 12 serves as a ventilation part.

The glove base material 1 is made of knitted cotton yarn and has breathability and hygroscopicity. The resin layer 2 has highly protruding irregular mesh-like anti-slip protrusions 3 formed by bursting of numerous bubbles in the resin liquid when the resin liquid adheres to the glove base material 1 is in a sol state. There are provided numerous irregular mesh-like recesses 5 and 6 formed by the formation of the anti-slip projections.

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 material 1 and recesses 6 whose bottoms do not reach the surface of the glove base material 1. 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 approximately 0.2 to 2.0 mm, and the resin liquid is adhered to the surface of the glove base material 1 (Fig. 4 a). reference). 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 the ruptured portion, which does not reach the glove base material 1 (see Fig. 4c).Furthermore, the air bubbles burst one after another in a sol state. Ru.
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 such that it easily bursts, and in this example, it is 300 CP as will be explained later.

Further, it is preferable to apply the resin liquid slightly thinly so that the glove base material 1 can be easily bent.

FIG. 5 is a partial end view of another embodiment.

In order to increase the protrusion of the anti-slip projections 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. The rest is the same as the previous embodiment.

An example of the blending of resin and an example of the manufacturing method for manufacturing the gloves according to the present invention are shown below. Note that parts indicate parts by weight.

This glove base material 1 is used as a back part 50 as shown in FIG.
Then, a part of the finger part 51 and a wrist part 52 that follow are placed on the glove mold 5 which is formed into a flat surface. Then, as shown in FIG. 7, the left and right glove molds 5 and 5a are brought into close contact with each other with their backs facing each other, and are clamped and fixed using an appropriate clamping tool 6 to form a large amount of air bubbles with a particle size of about 0.2 to 2.0 mm.

This glove base material 1 is lifted out of the resin liquid and placed in a sealed vacuum container, and the pressure is reduced to 400 mm/Hg using a vacuum pump to burst the bubbles. After that, at about 180℃
Heat for 20 minutes. In this way, the resin layer 2 is formed on the surface of the glove base 1 except for the back part 10, part of the finger part 11, and the wrist part 12, and the glove has good ventilation and sharp anti-slip protrusions. get the.

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

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

Therefore, it is possible to perform an anti-slip function against external forces from different directions.

(b) The glove base material is made of permeable cloth, and the resin layer 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 pass through the resin layer and escape to the glove base material side. Therefore, there is no film of water or oil intervening between the resin layer and the object to be handled, and the protrusions can directly adhere to the object to be handled without slipping due to the film of water or oil. can perform a function.

(c) Of the recesses in the resin layer, the non-permeable recesses have a suction cup shape, and interact with the projections to provide a sufficient anti-slip effect.

(d) The resin layer 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 layer is permeable, and there is also a ventilation section on the back side where there is no resin layer. For this reason, combined with the breathability of the resin layer, it does not get stuffy even when worn on the hand.

(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.
