Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a leather glove, for example,
More particularly, the present invention relates to a leather glove using a portion of leather conventionally discarded as waste as a material, and a method for manufacturing a glove made of a non-stretchable material such as leather.

[0002]

2. Description of the Related Art Conventionally, as gloves, for example, leather gloves for work, a part called so-called "genuine leather (surface leather)" or a part called so-called "floor leather" is used. Use one. For example, gloves using the above-mentioned genuine leather are used as gloves for assembling work of machines and the like, and the above-mentioned floor leather is used as gloves for work in fields related to steel, welding, or transportation.

[0003] When the above-mentioned floor leather is used as a material for gloves, "genuine leather" is sliced and separated from raw leather, and the remaining "floor leather" is separated from the remaining "floor leather" to the genuine leather side of the "floor leather". A portion where the leather density is “sparse” and easily becomes “separated” (referred to as “medium leather” in this specification) is peeled off, and then used. In other words, if such a middle leather is present on the surface of the floor leather glove, when the glove is used as a glove, the middle leather is peeled apart with the use.

[0004] In addition, since the inner leather peeled off when manufacturing working gloves made of floor leather as described above is in the form of small chips, it is not used as a leather product.
At present, it is treated only as waste.

Conventionally, as a work glove used in an environment where oil or the like adheres, there is a work glove in which a surface of a knit made of cotton or the like is coated with rubber. When rubber coating is applied to the surface of such a knit glove, put the knit glove on a hand model having a shape such that the gap between the fingers of the casting is open, and then put the liquid rubber in the container. It was immersed in the required area and was coated with rubber. Therefore,
Conventionally, it has been common knowledge in the industry that gloves made of a non-stretchable material, such as leather gloves, cannot be worn on a hand model having the above-mentioned shape, and cannot be coated with rubber. Some trial proposals have been made to coat the surface of leather gloves by applying a rubber solution with a brush, etc., but the coated rubber easily peels off, and practical use is required for use as work gloves. It was the current situation that it was poor.

The present invention has been made under such circumstances, and a glove in which middle leather, which is now simply discarded as waste, is effectively used as a material for working gloves, and a method of manufacturing the glove. The purpose is to provide.

[0007]

A leather glove according to the first aspect of the present invention uses, as a material, a medium leather portion obtained by slicing a medium leather portion located on the genuine leather side of floor leather, and uses the surface of the medium leather as a material. A resin coating (in this specification, a broad concept including natural rubber coating in addition to synthetic rubber coating,
(Which means a coating made of a substance that can reinforce the middle leather by being hardened with elasticity).

[0008] According to the leather gloves configured as described above, leather fiber density, which is a characteristic of medium leather, tends to be "sparse" and easily separated, but the surface is strengthened by resin coating. Reinforced, and at the part that touches the skin of the hand, the soft sensation characteristic of medium leather is obtained, and even if it comes into contact with sharp objects such as bamboo skewers or tinplate by resin coating, it can penetrate It is a work glove of excellent composition that does not have any. And, since the middle leather, which has been conventionally discarded as waste, can be effectively used, it is an excellent invention to solve the environmental problem today, in which environmental problems are being highlighted. As described above, since the resin-coated portion can effectively prevent stabbing into the hand side, the glove is preferable as a working leather glove used in an industry such as a garbage collection industry or a sorting of recyclable garbage.

In the above leather glove, if the resin coating is a rubber coating, and this rubber coating is applied to a portion other than the back of the hand, a functionally necessary and sufficient working leather glove is obtained. .

[0010] The method for producing gloves according to the second aspect of the present invention comprises:
A method for manufacturing gloves in which a resin coating is applied to the surface of a non-stretchable material, wherein a semi-finished glove in a state in which only the thumb side of the index finger of the glove is unsewn is attached to a hand model, A semi-finished product in a coating solution is immersed in a desired portion of the glove except for at least the unsewn portion so that the coating solution adheres thereto. The present invention is characterized in that sewing is performed on the side of the index finger on the thumb side.

However, by manufacturing in this manner, only the side of the index finger on the thumb side is not sewn on the surface of a glove made of a non-stretchable material such as middle leather which could not be resin-coated. Therefore, it is possible to apply a resin coating to a desired portion by attaching to a model of a hand having an open shape between rigid fingers and immersing the finger in a coating solution. Since the side portion of the side is a portion that does not originally need to be coated with a resin, there is no resin coating on the surface, and therefore, it can be sewn by a sewing machine after coating.

The glove manufacturing method according to the third aspect of the present invention is a method for manufacturing a glove having a resin coating on the surface of a non-stretchable material. The glove is attached to an inflatable / contractible hand model in which a space is formed between fingers by applying a fluid pressure to the inside of the glove from an initially freely shapeable shape. In a state in which a space is formed between the fingers, and in this state, the model of the gloved hand is immersed in the coating solution so that the resin solution adheres to a desired portion of the glove, and the resin coating by the immersion is formed. Later, the fluid pressure is reduced, and the glove is removed from the contracted hand model.

[0013] By manufacturing as described above, it is possible to attach the hand model in a contracted state to the surface of a glove made of a non-stretchable material such as middle leather, which could not be conventionally coated with a resin, and Subsequent inflation by applying fluid pressure creates a condition in which a space is formed between each finger, and in such an inflated condition, by immersing in a coating solution, the desired It becomes possible to apply resin coating to the location.

The non-stretchable material according to the method for producing gloves may be the middle leather obtained by slicing the middle leather portion located on the genuine leather side of the floor leather. Gloves may be work gloves.

In the above-mentioned method for producing gloves, if the resin coating is a rubber coating and a step of heating and drying is provided after the coating, rubber can be cross-linked while being attached to a hand model, This is an excellent manufacturing method in that the coated part of the glove can be made to be stable in shape in that state.

Further, in the above-mentioned method for producing gloves, the heating and drying step comprises two steps, the temperature in the first heating and drying step is 60 ° C. to 80 ° C., and the second heating and drying step When the temperature in the process is 95 ° C. to 105 ° C., a preferable structure is obtained in view of the above-mentioned crosslinking.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION A method for producing a leather glove (working leather glove in this example) and a non-stretchable material (middle leather in this example) according to an embodiment (example) of the present invention will be described below. This will be specifically described with reference to the drawings.

FIG. 1 is a perspective view from the back of the hand showing the overall shape of a working glove made of middle leather according to this embodiment.
FIG. 2 is a perspective view showing a state of a partially unsewn glove before being immersed in a coating liquid, and FIG. 3 is a view from the back side of a hand showing a state where an unsewn glove attached to a hand model is immersed in the coating liquid. FIG.

In FIG. 1, A is a working glove made of medium leather. As shown in FIG. 5, the middle leather K is
By slicing the genuine leather (skin leather) G portion from the cow's raw leather F with a slicing machine, the remaining portion is further deleted by slicing the so-called floor leather H1 portion used as a material of the product. The remaining leather located on the genuine leather G side of the floor leather H1. The medium leather K has a fiber density of "sparse" and has a higher strength than the genuine leather G and the floor leather H1. It has the property of being weak and easily falling apart. In the case of the present embodiment, the medium leather K has a thickness of about 1 to 1.2 mm.
Then, this medium leather K is cut in accordance with the pattern of each part of the glove in the same manner as when making a known work glove A for work.
Get each part. Then, as shown in FIG. 2, the above parts of the other part of the glove are processed in the same manner as in the known glove working process so that only the side 2A on the thumb side of the index finger 2 of the glove is unsewn. And sew. Next, as shown in FIG. 2, the glove A1 in the unsewn state (semi-finished state) of only the side 2A on the thumb side of the index finger 2 is put on a model R of a cast hand as shown in FIG. The model R of the hand has a shape in which the space between the fingers of the hand is widened so that both sides of the finger can be coated. Therefore, the thumb R1 part of the model R of the hand is in a state of being expanded as compared with the part of the wrist R6. The hand model R in such a state is put on the glove A1 shown in FIG. 2, in which only the side 2A on the thumb side of the index finger 2 is not sewn. That is, the side part 2A on the thumb side of the index finger 2 of the glove is
Since it is not sewn, the thumb part of the glove A1 can be freely spread with respect to the upper part of the glove A1, and as a result, even if the glove material itself has no elasticity, the middle leather K can be used.
It can be easily worn on the hand model R. And
In a state where the partially unsewn glove A1 is put on the hand model R, as shown in FIG. 3, the palm side of the glove A1 is placed in a flat container (pat) containing a coating liquid to a certain depth. Immerse it on the lower side. In the case of this embodiment, a rubber liquid is used as the coating liquid. This rubber liquid
Natural rubber or synthetic rubber may be used, but in this example, "IR latex" described below is used. That is, I
R latex is a sulfur water dispersion (solid content 25%) with a trade name of "Seporex 1R100" (trade name of Sumitomo Seika Co., Ltd.)
) At a solids concentration of 1.5, a zinc oxide aqueous dispersion (solids concentration 25%) at a solids concentration of 0.5, and a Bz aqueous dispersion (solids concentration 20%) at a solids concentration. 0.
5. Add 0.5 parts of TRA aqueous dispersion (solids concentration of 20%) in solids concentration and 1.0 parts of EBP aqueous dispersion (solids concentration of 20%) in solid concentration and mix. , 12-2
It is obtained by allowing it to stand, store, and mature for about 4 hours. If necessary, a pigment may be added to the rubber if desired.

By the way, as shown in FIG. 3, the immersion is performed up to a position where the portion to be coated is immersed. When the coating liquid adheres to a desired portion of the glove A1 by immersing the coating liquid in the rubber liquid as described above, in this state, the palm portion is turned upward and the temperature is about 60 ° C. to 80 ° C. ,
In this embodiment, the rubber-coated portion is heated and dried at about 70 ° C. for about 1 hour. The heating may be performed by heating and drying by putting gloves in a high-temperature chamber, or by heating and drying by blowing hot air. Desirably, heating and drying by putting gloves in the chamber is desirable in that the inside of the rubber can be heated at a uniform temperature. And
Next, at a temperature of about 95 ° C to 105 ° C, in this example about 1 ° C.
By heating and drying at a temperature of 00 ° C., the rubber is cross-linked (vulcanized) and its form (shape) is fixed. This heating and drying is performed in the same manner as in the heating and drying described above. Finally, the index finger 2 of the unsewn gloves
Is sewn by a sewing machine used for sewing ordinary leather. In this case, since the portion to be sewn is not coated with the rubber, it is possible to sew with a sewing machine.

Thus, as shown in FIG. 1, the working gloves manufactured through the above-described steps except for the back of the hand including the unsewn portion on the thumb side of the forefinger,
In other words, the glove is a working glove in which the palm and both sides of the finger are rubber-coated. According to the present invention, water-resistant and oil-resistant work gloves can be formed by the discarded middle leather K which has been peeled off when manufacturing work gloves made of floor leather in the past. It is possible to provide gloves which can be manufactured and are made of unusual middle leather K as a material and the surface of the middle leather K is coated with rubber.

In the working gloves in which the surface of the middle leather K is coated with rubber as described above, the portion of the hand that touches the skin has a soft touch unique to the middle leather K, and the surface is coated with rubber. Therefore, the hand can be protected even if a sharp object comes into contact or a blade comes into contact. In addition, what has been conventionally discarded can be used effectively, which can contribute to environmental improvement.

By the way, in the embodiment relating to the method for manufacturing the glove, the case where the medium leather is used as the material of the glove has been described. However, the method for manufacturing the glove is based on a non-stretchable material other than the medium leather, such as cloth. Needless to say, the present invention can be applied to gloves such as.

The working gloves having a rubber-coated surface of a non-stretchable material such as the above-mentioned medium leather K can also be manufactured by another manufacturing method described below.
Hereinafter, examples of the manufacturing method will be described. That is,
In the same manner as in the above method, a sheet-like medium leather K is obtained by slicing, and this medium leather K is cut into each part of the glove in the same manner as in the case of manufacturing ordinary gloves. Sewing in the form of gloves. So, so far,
Except for using the medium leather K as a material, it is the same as the production of ordinary gloves. Next, a glove-shaped hand model RX in the form of an inflatable / contractible glove as shown in FIG. Contracted (not expanded)
Then put on gloves. The hand model in the form of a glove is made of a flexible and air-tight model, for example, a cloth with a seal having an inner surface coated with rubber. ~ 2kg / cm ²
, A model of a substantially rigid hand with a certain degree of stiffness and an open space between fingers (see the two-dot chain line in FIG. 6), and reducing the internal air pressure to, for example, 0.8 to 1 kg / cm ² By reducing, the shape becomes freely variable (see the solid line in FIG. 6) due to a decrease in hardness to some extent. Therefore, the internal air pressure is 0.8-1 kg
/ Cm ² , gloves are attached to the hand model RX in a state where the thumb can be freely changed, and after the attachment is completed, the internal air pressure is increased to 1.5 to ² kg / cm ² , and the hand model Can be changed to a state in which a space can be formed between the fingers (see a two-dot chain line in FIG. 6).

Then, as described above, the hand model wearing the gloves is immersed in the above-mentioned rubber coating liquid in a state changed so that a space can be formed between the fingers in the same manner as in the above-mentioned embodiment. It should be done. Also, after heating,
By performing drying in the same manner as in the above-described embodiment, rubber coating can be applied to a desired portion of gloves made of medium leather. Then, after the above processing, the coated gloves may be removed from the hand model RX.

In particular, according to this embodiment, it is possible to rubber-coat a desired portion, including the portion on the thumb side of the index finger of the glove, which could not be coated in the above embodiment, and if necessary, the entire glove. In this respect, it has excellent features.

[0027]

According to the leather gloves according to the present invention, by using the medium leather conventionally treated as waste as a material, resources can be effectively used, and the medium leather with a good touch to the skin of the hand. By applying the resin coating to the surface of the middle leather while taking advantage of the features of the above, it is possible to provide gloves which are not inferior in strength, and which are resistant to sharp objects or blades and are suitable as work gloves. .

Further, according to the method for manufacturing gloves of the present invention, gloves made of a material having no elasticity, which could not be coated with resin, can now be freely coated with resin. Thus, it is possible to actually provide gloves made of the above-mentioned medium leather and coated on the surface with resin.
