The present invention relates to an ultra-thin coating gloves and a method for producing an ultra-thin coating gloves.

More specifically, the operator can perform the precise work by allowing the operator to feel the texture of the skin while wearing the gloves to the maximum, and when the LCD monitor or the mobile phone liquid crystal surface is assembled, work does not leave fingerprints on the liquid crystal surface. A method of manufacturing ultra-thin coating gloves and ultra-thin coating gloves that can prevent contamination in a clean room due to fine dust caught between fabric tissues because the outer surface of the working cotton gloves is fabric type. It relates to a glove manufacturing method.

In general, polyurethane coated gloves made from polyurethane resins are widely used for industrial purposes such as general companies, fruit farms and work, hobby activities such as fishing and sports, or for home use, but work precisely with the thickness of existing products. There is a limit that can not be.

As a method of manufacturing work gloves using such a polyurethane resin, there are a dry method and a wet method. Drying method is manufactured by coating gloves using polyurethane compounding resin and then drying process. Waste water is not generated to prevent environmental pollution and reduce manufacturing time by reducing manufacturing time by simplifying the process. However, due to the nature of the manufacturing method, it is inconvenient to feel when working with polyurethane because it does not produce micropores, and the coating solution is thickly applied, which makes the operator feel uncomfortable. It is difficult to control the grip property of the cotton so that the object to be transported can not be prevented from slipping in the hand.

On the other hand, the wet method can be obtained by drying the method by coating a solution of a mixture of an emulsifier and a toner in a polyurethane resin by impregnating gloves, then coagulating with an appropriate coagulating solution to extract the solvent into the coagulating solution to form a microporous coating. It gives the breathability, volume, touch, etc. without.

However, the biggest feature of the polyurethane coated glove produced by this wet method is that the polyurethane resin coated on the outer surface of the glove penetrates into the inner surface of the glove and the coated surface is flat without bending.

Therefore, since the polyurethane resin penetrates the inner surface of the glove, it comes into direct contact with the hand, causing discomfort, and due to the sweat generated from the hand, the polyurethane resin decomposes due to moisture and salts, and thus generates dust. Rather, decomposition products of the polyurethane resin on the hand will adversely affect the human body.

In addition, since the coated surface is flat without bending, there is a problem of deteriorating workability by dropping the product from the hand during operation and gloves often flowing down, and it is possible to manufacture thinner than dry coating gloves, but it is also suitable for precise work. It does not have a form.

Therefore, the glove used for the above uses should be suitable to grip the glove surface to prevent the slip of the object during work, and should be coated with a thin film as much as possible to transmit the touch to the operator as much as possible, in addition to the flexibility and Physical properties such as hygroscopicity of the fabric lining and adhesion to maintain the durability of the product are required.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to allow the operator to feel the texture felt to the maximum while wearing a glove to perform a precise operation When assembling the LCD monitor or mobile phone liquid crystal surface, it can work without leaving fingerprints on the liquid crystal surface, and the outer surface of the working gloves can be prevented from contamination in the clean room due to the fine dust caught between the fabric tissues. It provides an ultra-thin coating gloves and a method for producing an ultra-thin coating gloves.

In addition, another object of the present invention is to prevent the contamination caused by fine dust caused by the separation of the fabric tissue generated through the seam by making the glove not exposed to the seam, and the foreign substances or drugs through the seam to be introduced primarily It provides an ultra-thin coating gloves and ultra-thin coating gloves manufacturing method that can be prevented by.

One embodiment of the present invention proposed to solve the technical problem as described above, in the ultra-thin coating gloves, the ultra-thin coating gloves, the coating surface of the two coating fabrics formed by applying a polyurethane coating liquid on the woven fabric top It is characterized by having a suture sealed by high frequency equipment.
