Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cold-proof gloves used for various tasks in freezers and cold regions, and for riding bicycles and motorcycles, and a method for manufacturing the same.

Conventional winter gloves include leather gloves and rubber gloves with cloth attached to the inside, as well as waterproof outer gloves and heat-retaining inner gloves that are bonded together using adhesive. Those with a combined structure are used. However, leather gloves are water-permeable and cannot be used in areas where water is present, while rubber gloves can prevent water from passing through, but have the disadvantage of lacking heat retention. In addition, in a structure in which an outer glove and an inner glove are bonded together using an adhesive, for example, the outer glove is made of stockinette fabric and the surface is coated with vinyl chloride resin or rubber, and the inner glove is made of stockinette fabric. A structure in which a sponge is coated on the fabric of the inner glove is used, and adhesive is applied to the surface of the sponge of the inner glove, and the sponge is inserted into the outer glove and dot-glued, or the desired thickness is applied to the surface of the hand shape. Apply vinyl chloride resin to the surface and heat treat it to form a vinyl chloride resin film. Apply adhesive to the surface of the film, cover it with pre-sewn cloth gloves and adhere, then reverse peel. It had a structure manufactured by However, with these gloves, it takes a lot of work to attach the outer glove and the inner glove, which increases costs and does not improve productivity.Also, because adhesive is used for bonding, the work environment is poor, and the gloves It had drawbacks such as the adhesive part peeling off during use and problems with texture and flexibility.

In view of the various drawbacks of the conventional cold-proof gloves as described above, the inventors of the present invention have conducted intensive research and have completed the cold-proof gloves and the manufacturing method thereof according to the present invention.

That is, the present invention has a laminated structure consisting of a knitted base fabric, a foamed urethane resin layer, and vinyl chloride resin powder sealed from the inside by a fluidized dipping method, and then a layer of vinyl chloride resin or urethane resin on top. , a cold protection characterized in that most of the vinyl chloride resin powder is fused to the vinyl chloride resin or adhered to the urethane resin, and a part remains in the urethane resin foam in a powder state. Gloves are made by laminating urethane resin foam sliced into sheets on one side of a stockinette-knit base fabric.The stockinette-knit base fabric, which has a urethane resin foam layer on one side, is cut and sewn into gloves. a first step, the glove is placed on an aluminum glove mold with the knitted side inside, and a second step is to seal the surface of the urethane resin foam of the glove with vinyl chloride resin powder by a fluidized dipping method; It consists of a third step of applying vinyl chloride plastisol or urethane resin emulsion to the surface and then heat-treating it, and in the third step, most of the vinyl chloride resin powder is fused with the vinyl chloride plastisol, Alternatively, the present invention provides a method for manufacturing cold protection gloves having a layer of vinyl chloride resin or urethane resin on the surface thereof, which is adhered to the urethane resin emulsion and a portion thereof remains in powder form in the urethane resin foam. .

EMBODIMENT OF THE INVENTION Hereinafter, the cold protection glove and its manufacturing method based on this invention are demonstrated based on drawing.
