Description

How to manufacture household rubber gloves{A PAIR OF RUBBER GLOVES MANUFACTURING METHOD}

The present invention manufactures a household rubber glove integrally formed with a lining glove woven with fibrous thread and an outer shell coated with water-soluble polyurea on the surface of the lining glove, as well as manufacturing a household rubber glove by coating it with water-soluble polyurea. This is about a method of manufacturing eco-friendly household rubber gloves that prevents environmental pollution by industrial wastewater because the manufacturing process does not include a washing process to wash away carcinogens and hazardous substances with washing water.

In general, household rubber gloves are made of raw rubber, latex, or nitrile and are not breathable, so if you wear household rubber gloves for a long time, the sweat secreted from your hands wets the inside of the gloves, and this sweat causes eczema or itching on the skin. There is.

In addition, when using cold or hot water while wearing household rubber gloves, the cold and heat are directly transferred to the hands, which has the disadvantage of causing frostbite, cold sensitivity, or burns when used for a long time.

Conventional household rubber gloves are made entirely of raw rubber or latex, so they are very uncomfortable to wear due to their elasticity, and when worn for a long period of time, they do not easily come off due to sweat inside, and the sleeves often slide down, making them inconvenient to use. do.

Accordingly, in order to solve various problems with conventional household rubber gloves, the following prior technologies have been disclosed.

First, in Korean Patent Publication No. 10-2008-0046834, it was manufactured by adding nanosized aluminum hydroxide and silver (Ag) to a typical latex composition, thereby improving eczema and itching that occurred during long-term use by providing antibacterial properties.

However, all of these prior technologies had the disadvantage of only improving antibacterial properties and failing to improve the thermal insulation and usability of rubber gloves.

In addition, some of the conventional household rubber gloves are used with an inner skin formed in the same way as the inside of household rubber gloves to prevent frostbite, coldness, or burns when worn for a long period of time in winter.

To form the lining in the household rubber gloves, cut two pieces of non-woven fabric in the shape of a hand, sew the edges of the fabric to form the lining, attach it to a mold, and then insert the mold into the rubber glove to form an inner lining. Adhere.

However, in order to insert the lining inside a household rubber glove as described above, the inner size of the household rubber glove must be made larger. When wearing a household rubber glove, an unnecessary space is formed between the hand and the lining, which reduces wearing comfort and reduces elasticity. There is a problem in that the household rubber gloves and the lining are easily separated due to repeated bending and unfolding of the fingers, making them less durable.

In addition, conventional household rubber gloves are mainly manufactured using latex, which contains carcinogens and hazardous substances that are harmful to the human body, so the washing process of washing with water is repeatedly performed to remove these substances, which increases the amount of water used. Because there are so many, manufacturing costs rise, and because environmental pollution is caused in the process of discharging polluted water, there is a problem of additional processing costs.

In addition, skin diseases such as housewife's eczema are becoming more serious as people wear household rubber gloves with their bare hands. The cost of treating this is also high, it is a disease that is not easily treated, and because it is contagious, it has a serious impact on eating habits and social life. There are problems that can cause problems.

Additionally, recently, gloves made from nitrile (acrylonitrile butadiene rubber) or a composite of latex and nitrile are widely used as disposable gloves in the kitchen when washing dishes or cooking food.

The nitrile gloves are mainly made of natural latex and have the characteristic of being closely adhered to the outer circumference of the hand when worn. Once worn, the nitrile gloves may become humid when sweat accumulates inside the nitrile gloves, causing eczema, etc., making it difficult to wear them for a long time and taking them off. In this case, the nitrile gloves themselves are curled, making it difficult to reuse them to insert a finger again, so they are used only for one-time use and are discarded, adding to the economic burden.

In addition, Republic of Korea Patent Application No. 10 - 2018 - 0113020 "Industrial gloves coated with polyurea resin composition and silicone resin and manufacturing method thereof" was previously filed.

The industrial gloves of the previously filed patent application number 2018 - 0113020 are gloves;

A first coating film formed on the glove and containing a polyurea resin; and a second coating film formed on the first coating film and containing a silicone resin, wherein the first coating film is partially impregnated with at least a portion of the polyurea resin into the inner skin of the glove, wherein the inner surface of the glove is an inner membrane layer formed to prevent penetration; and a coating layer formed by the remainder of the polyurea resin on the outer surface of the glove, wherein the polyurea resin of the first coating film has a viscosity in the range of 100 cps to 300 cps, and the silicone resin of the second coating film has a viscosity of 100 cps to 300 cps. has a range of 6,000 cps to 15,000 cps

The industrial gloves of the previously filed patent are formed by coating a portion of the outer peripheral surface of the glove with polyurea resin, and forming a coating film inside the glove to prevent the polyurea resin from penetrating into the inner surface of the glove.

Meanwhile, Korean Utility Model Application No. 20 - 2001 - 0011472 "Rubber Gloves" was selected, but rubber gloves, which are usually made of soft synthetic resin material with elasticity, have a structure in which multiple suction plates are formed integrally in the gripping part. It comes true.

The previously filed rubber gloves are made of synthetic resin material and only provide a non-slip function to prevent slipperiness.

In addition, conventional household rubber gloves do not include cut prevention, cold protection, heat resistance, or stab prevention functions depending on the purpose of use, so you must wear thick gloves and then wear household rubber gloves to perform the relevant work.

In other words, depending on the purpose for which the user uses household rubber gloves, for example, they must have a heat resistance function in order to smoothly carry out cutting, hot, cold, or frying cooking tasks without the worker getting injured, but they do not have any function at all. Therefore, there is the inconvenience of having to wear separate gloves or taking off household rubber gloves and putting on other gloves.

There is a problem in that wearing cotton gloves on top of household rubber gloves slows down the movement of the fingers, making them less comfortable to wear.

Also, while preparing ingredients and cutting with a knife in the kitchen, you need to protect your hands from getting cut by the knife. To prevent finger movements from becoming sluggish, wear thin cotton gloves and then wear household rubber gloves, but be careful. If the finger area is cut with a knife, the outer layer is easily damaged, so there is a problem with cotton gloves not properly protecting the finger.

The reason why the above problem occurs is that the inner skin is formed by simply attaching fiber yarn to the inner circumferential surface of household rubber gloves, so it cannot be selected for use (cooking process).

In addition, Patent Application No. 10 - 2007 - 0069761 was filed for “Inner gloves for rubber gloves that absorb sweat and moisture.”

The inner gloves are made of napkin paper or non-woven fabric and provide inner gloves for rubber gloves that absorb sweat and moisture and are designed to fit a person's hand. However, when using rubber gloves, they are provided so that they can be easily put on and easily taken off. There is the inconvenience of having to prepare separate inner gloves.

In addition, in the process of dipping a rubber glove in a mold and then drying it in a drying room, hot air is supplied only to the surface of the rubber glove and it dries from the surface to the inside, so there is a problem that the drying time takes a long time and productivity is reduced.

Republic of Korea Patent Publication No. 10-2008-0046834 “Functional latex rubber gloves with breathability and antibacterial properties and manufacturing method thereof” Republic of Korea Patent Application No. 10-2018-0113020 “Industrial gloves coated with polyurea resin composition and silicone resin and manufacturing method thereof”

As a means of solving the above problem, the household rubber gloves of the present invention are environmentally friendly as they do not involve a cleaning process, unlike the conventional ones, as the outer shell is coated by dipping water-based polyurea on the surface of the woven inner glove, and hot air is also supplied to the inside of the mold. The purpose is to shorten the drying time.

As a means of solving the above problem, the present invention relates to household rubber gloves, which include an inner skin glove woven with fibrous thread, and a household rubber glove whose outer shell is formed by coating the surface of the inner skin glove with water-soluble polyurea. to provide.

As described above, the household rubber gloves and manufacturing method of the present invention are manufactured by coating water-soluble polyurea on the surface of a lining glove woven with fibrous thread, and do not include a washing process in the manufacturing process, so industrial wastewater is not generated. Since water-soluble polyurea itself is an eco-friendly coating liquid, it is effective in manufacturing eco-friendly household rubber gloves that prevent environmental pollution.

In addition, since a cleaning process is not included, the manufacturing process is shortened, which has the effect of reducing manufacturing costs.

In addition, the present invention manufactures rubber gloves in which the outer shell is formed by dipping water-soluble polyurea into an inner glove woven with fibrous thread, providing excellent wearing comfort and providing convenience to the user by making it easy to take off and wear.

In addition, the gauge value of the lining gloves (2) is limited to 7g, 10g, 13g, 15g, 18g, 21g, etc. depending on the intended use, and the color is different depending on the gauge value and function, providing convenience to the user. There is.

The household rubber gloves of the present invention are manufactured according to the gauge value and material of the lining gloves.

It is effective in preventing cold, heat resistance, cuts, static electricity, and stabbing.

The lining gloves of the present invention's household rubber gloves have the effect of being able to be used by weaving various functional fiber materials such as cotton yarn, nylon yarn, poly yarn, spandex, microfiber, steel yarn, and HEEP yarn depending on the intended use.

Figure 2 is a perspective view showing the household rubber gloves of the present invention.
Figure 3 is a cross-sectional view showing the household rubber gloves of the present invention.
Figure 4 is a perspective view showing the household rubber glove mold of the present invention.

In order to achieve the above objectives and effects, the present invention will be described in detail with the accompanying drawings as follows.

Figure 1 is a flowchart showing a method of manufacturing household rubber gloves of the present invention, Figure 2 is a perspective view showing the household rubber gloves of the present invention, Figure 3 is a cross-sectional view showing the household rubber gloves of the present invention, and Figure 4 is a cross-sectional view showing the present invention household rubber gloves. This is a perspective view showing the household rubber glove mold of the present invention.

The method of manufacturing household rubber gloves of the present invention proceeds with the step of preparing woven lining gloves (2) by varying the thread gauge of the fiber material according to the intended use of the household rubber gloves (1).

The yarn gauges of the above fiber materials are varied and are woven into 7g, 10g, 13g, 15g, 18, and 21g.

If the weight of the inner gloves (2) is divided into six types, the higher the gauge value, the more detailed the tissue composition of the inner skin gloves, and the lower the gauge number, the thicker the glove, resulting in cut resistance and heat resistance. The strength to withstand external threats, including.

In addition, the lower the gauge value of the inner skin glove (2), the better the thermal insulation and cooling effect, making it easier to touch hot or cold objects, and the higher the gauge number, the better wearing comfort it provides, providing convenience to the user.

In addition, the step of placing water-based polyurea in a stirring tank and stirring it while maintaining the temperature within the range of 20°C to 40°C is performed.

When the temperature of the water-based polyurea stirred in the stirring tank is 20°C or lower, the water-based polyurea gradually hardens, and when it is above 40°C, the water-based polyurea becomes diluted and dipping is not easy, so an appropriate temperature is important.

The step of forming air foam is performed by supplying air to the water-based polyurea soaked in the stirring tank.

If air foam is formed on the water-based polyurea, it can be used as everyday waterproofing, and if air foam is not formed, 100% waterproofing is possible.

Therefore, the present invention can selectively proceed with the process of forming air foam in water-based polyurea or not forming air foam.

The step of supplying water-based polyurea from the stirring tank to the dipping tank is performed.

A mold (4) in which air spray holes are arranged on the palm, fingers, and back of the hand for the endothelial glove (1) is prepared, and then the endothelial glove (2) is inserted into the outer peripheral surface of the mold (4).

The endothelial glove (1) inserted into the outer peripheral surface of the mold (4) is positioned up to the wrist or forearm area of the mold (4) at 20 to 50 cm in accordance with the length of the mold (4).

The above household rubber gloves can be worn up to the wrist or arm by varying the length.

The dipping step of forming the outer shell (3) is performed by inserting the mold (4) in which the endothelial glove (1) is combined into a dipping tank and fully coating the entire endothelial glove with water-soluble polyurea.

The reason for repeating the dipping step of forming the outer shell (3) by coating the surface of the inner skin glove (2) 2 to 3 times is to prevent water from penetrating into the micropores, thereby improving waterproofness and preventing slipping on the surface. This is a configuration that not only adds a non-slip function but also improves durability.

The mold (4) in which the surface of the inner skin glove (2) has been dipped is taken out of the stirring tank and transported to a drying room, and then the household rubber glove (1) in which the outer skin (3) has been dipped is dried.

As described above, when drying household rubber gloves (1) in a drying room, in order to shorten the drying time, hot air is supplied into the mold (4) through the open wrist part of the mold (4), and the inside of the mold (4) is heated by hot air. As it expands, it proceeds with the step of naturally spraying hot air in the direction of the inner glove (2) and outer shell (3) through the air spray hole (5).

As described above, if hot air is uniformly sprayed from the inside of the mold (4) toward the inner glove (2), the inner glove (2) and the dipped outer shell (3) will be dried quickly by the hot air sprayed, thereby shortening the drying time. You can.

The reason why the air spray hole (5) can be formed in the mold (4) is to insert the inner glove (2) into the mold (4) to prevent water-based polyurea from penetrating into the mold (4) during dipping. Because you can.

That is, the present invention can shorten the drying time by simultaneously drying the outer and inner gloves by simultaneously supplying hot air to the outside and inside of the mold in the drying room.

When the dried gloves are separated from the mold, household rubber gloves are completed.

The present invention adds an antibacterial ingredient to the inner skin glove or outer shell to have an antibacterial function.

In addition, when weaving inner gloves, antibacterial yarns are included to provide antibacterial properties to the gloves.

Meanwhile, in another example, the same effect can be obtained by dipping using water-soluble polyurethane (PUD), which has similar components to water-soluble polyurea.

The above-mentioned household rubber gloves are formed of an inner glove woven with fibrous threads and an outer shell coated with water-soluble polyurea on the surface of the inner glove, thereby omitting the cleaning process of washing with washing water when manufacturing household rubber gloves, making it an eco-friendly rubber product. Gloves are provided.

In addition, the materials of the inner gloves are manufactured using cotton yarn, nylon yarn, poly yarn, spandex, special yarn, and long fibers such as microfiber, steel yarn, HPPE, aramid, acrylic yarn, and brush, thereby improving the user's use and function. You can choose depending on.

In other words, cut fibers such as steel thread, tungsten, HPPE, and heat-resistant aramid are used to prevent cuts with knives when touching hot objects, and in winter or frozen warehouses, cold-proof fibers including brush are used.

In addition, in another embodiment, the household rubber gloves of the present invention can be used in medical facilities and semiconductor clean rooms depending on the intended use.

In addition, if the mold is molded to closely resemble the shape of the hand through 3D work, and then the lining gloves are inserted and then coated, the fingers can spread and bend more naturally when worn, providing excellent wearing comfort.

The household rubber gloves of the present invention provide excellent wearing comfort, such as disposable latex gloves and disposable nitrile gloves, and can be used as a replacement. They are eco-friendly and economical because they are used continuously rather than disposable.
