Description

Manufacturing method of rubber gloves having patterns of different colors

The present invention relates to a method for manufacturing a rubber glove mainly used when housewives, such as washing dishes, washing at home, more specifically in the known method of manufacturing rubber gloves, a portion of the hand is engraved in a specific shape It relates to a manufacturing method of rubber gloves, characterized in that by dipping by injecting a latex liquid of a product color and a different color to the engraved part of the mold and semi-dried.

In general, rubber gloves are molded by dipping or coating a mold dried by washing with a raw resin solution such as a natural latex liquid, a raw rubber liquid, an elastic polyurethane liquid, and brine treatment, It is prepared by drying, separating from the mold and then treating.

However, since rubber gloves flow down the parts above the wrist, foreign substances, waste water, and filthy water flow into the insertion holes, so the parts over the wrist should have excellent flexibility and elasticity. The parts under the wrist should have excellent wear resistance and friction because they are mainly in contact, but since the known rubber gloves are made with the same thickness as a whole, the parts under the wrist have poor wear resistance and friction and the parts over the wrist are not satisfactory in flexibility and elasticity. There is this.

In addition, in the conventional manufacturing method, since the depth of the dipping is greater than the length of the rubber gloves, even when dipping a plurality of times, the rubber gloves are colored in the color of the raw resin solution to be finally dipped, resulting in poor aesthetics.

In order to solve the above problems, the hand-shaped mold is dipped into the raw resin, but the dipping depth is at least two times, and the dipping depths are different by using the raw resin having different compositions for each dipping. The coating was optimized to optimize the characteristics of the rubber gloves, and by dipping by adding different dyes or pigments to the raw resin solution every time dipping, rubber gloves having various colors could be easily manufactured.

However, since the conventional rubber gloves are manufactured by applying a liquid latex to a hand-shaped mold and forming them, only the same color can be formed so that a logo or a specific pattern unique to the product can not be formed. In order to enhance the fashion and advertising effect on the product, if a certain shape of the attachment is attached to the finished product, there is a problem that the elasticity of the original function of rubber gloves is poorly adhered.

Accordingly, an object of the present invention is to provide a method of manufacturing a rubber glove that can enhance the fashion and advertising effect of the product by forming a specific pattern during the molding of the product with the same material as the rubber glove.

In order to achieve the above object as well as another object that can be easily expressed in the present invention by injecting a latex liquid of a product color and a different color to the engraved part of the mold of the hand shape engraved in a specific shape in a part to dry Thereafter, the mold (mould) was dried by brine treatment, dried by primary dipping, dried by secondary brine, dried by secondary dipping and dried, then removed from the mold and dried by acid treatment to obtain a finished product. A logo or a specific pattern could be formed in a different color from the product color, thus enhancing the advertising effect and fashion and making the product highly value added.

1 is a manufacturing process diagram of the rubber gloves of the present invention.

The present invention will be described in more detail based on the accompanying drawings.

1 is a manufacturing process of the rubber glove of the present invention, the rubber glove of the present invention is a mold after the semi-drying by injecting a latex liquid of a product color and a different color to the engraved part of the mold of the hand shape engraved in a specific shape The mold is dried by brine treatment, dried by primary dipping, dried by secondary brine treatment, dried by secondary dipping and dried, and then removed from the mold and acid-treated to dry.

It is the present invention that the logo and specific pattern of the product is to be formed in the same material as that of the rubber glove to enhance the distinctiveness and fashion of the product by forming the logo or specific shape of the product in a different color. To ensure complete adhesion, first inject a latex solution of a different color from the rubber gloves into the engraved part of the hand-shaped mold.

Injection of latex liquid is done by brushing, spraying, or eyedropper. When applying latex with brushing, the mold must not be salted. This is because latex solidifies instantaneously due to the salt water treatment, making it difficult to coat the latex with a brush. In the case of the spray method, the salt water treatment may be performed. In the case of the dropper method, the salt water treatment may or may not be performed depending on the situation. No problem.

By forming a latex pattern of a different color on the engraved portion of the mold by the above-described method, and salt water treatment is carried out in the same manner as the conventional rubber gloves manufacturing process to produce rubber gloves.

However, if dipping is performed in a state where the latex pattern formed on the engraved portion of the mold is less dry, there is a problem that the latex injected into the engraved portion of the mold flows down and the pattern is not formed well. There is a disadvantage in that the adhesion of the pattern is reduced after commercialization.

In general, it depends on the composition, viscosity, etc. of the dry state latex of the latex pattern formed on the engraved portion of the mold, the drying time may be changed depending on the temperature and room temperature of the mold, and as a result of repeated experiments, the moisture content of the latex liquid Most effective at 20-40%.

In addition, the rubber gloves of the present invention, after washing the hand-shaped mold and brine treatment, and dried, dipping (dipping) in the raw resin solution, and dried by brine treatment to separate the molded rubber gloves from the mold and after treatment In the manufacture of gloves, a raw material resin having different viscosity and composition every time dipping is performed by appropriately drying and dipping at least two times by injecting a latex solution of a product color different from the product color into the engraved part of the mold in which the specific shape is engraved in the brine treatment. By using a liquid, and dipping time and depth to be made by dipping method, by coating the raw resin and color of the composition with different composition for each part of the rubber gloves to improve the added value by increasing the aesthetics of the manufactured rubber gloves. Can be.

For example, during the first dipping, the depth of dipping is adjusted beyond the length of the rubber gloves, and the raw resin solution with excellent flexibility and elasticity required at the wrist or more portion of the rubber gloves is used. In the second dipping, the rubber gloves are used. Adjust the depth of dipping to the length of the wrist and use the raw resin solution with excellent abrasion resistance and friction required in the wrist below the rubber gloves, and use the color of the raw resin solution used for the first and second dipping. By differentiating, not only the color is different from the wrist, but also the physical properties required in each part of the rubber gloves can be easily satisfied.

As the raw material resin, any raw material resin which can be rubber glove such as natural latex liquid, raw rubber liquid, elastic polyurethane liquid, etc. can be used, and every dipping depends on the required physical properties of the raw material liquid. The addition of various additives can be easily inferred by those of ordinary skill in the art.

In addition, the raw material resin may be added dyes or pigments that can each express a different color every time dipping, the concentration and viscosity of the raw material resin solution can be adjusted according to the thickness of the rubber gloves to be manufactured, ease of manufacture and the like.

In the first dipping, the raw resin solution is filled and the hand-shaped mold is inserted into the mold engraved with the hand shape, but the inner surface of the engraved mold can be deformed so that a protrusion may be formed on the palm part to improve the frictional force. In the second or more dipping, by using the engraved mold in the same shape as the part of the rubber gloves to be coated or by adjusting the dipping depth, the raw resin having different colors and compositions for each part of the rubber gloves is coated.

In addition, the dipping time during dipping can be easily adjusted by the concentration and viscosity of the raw material resin to be used, the thickness of the rubber gloves to be molded and the like.

As described above, in the manufacture of rubber gloves, a latex liquid of a product color and a different color is injected into the engraved part of the mold in which the specific shape is engraved prior to the brine treatment, and dried appropriately two times or more, and the viscosity and By using the raw material resin composition with different composition and adjusting the dipping depth, it is possible to have the characteristic that satisfies the different color and the required property for each part, and it has different characteristics for each part by forming the product logo or specific pattern different from the color of the product. And it is a useful invention to obtain a rubber glove excellent in fashion.
