Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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-bonded, or the desired thickness is applied to the flat surface. A vinyl chloride resin film is formed by applying vinyl chloride resin to the surface and heat-treating it, then applying an adhesive to the surface of the film, placing a pre-sewn cloth glove on top of it, crushing it, and then inverting and peeling it off. 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 the texture and flexibility were poor.

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

That is, the present invention provides cold protection gloves having a laminated structure consisting of a stockinette-knitted base fabric, a urethane resin foam layer, a stockinette-knitted base fabric, and a vinyl chloride resin or urethane resin layer from the inside, and Gloves are sewn by cutting a urethane resin foam layer made by slicing urethane resin foam into sheets and pasting stockinette-knitted base fabrics on both sides and having stockinette-knitted base fabrics on both sides.

The glove is placed on an aluminum glove mold, and the surface of the glove is coated with vinyl chloride plastisol or urethane resin emulsion and heat treated to produce cold protection gloves having a layer of vinyl chloride resin or urethane resin on the surface. The present invention provides a method for manufacturing winter gloves.

Hereinafter, a cold protection glove according to the present invention and a method for manufacturing the same will be explained based on one drawing.

Figure 1 shows a urethane resin foam layer made by slicing urethane resin foam into sheets and pasting stockinette-knit base fabrics on both sides.The urethane resin foam layer has stockinette-knit base fabrics on both sides of the urethane resin foam layer, which is then cut and sewn. Partially cutaway perspective view of gloves (A
) and a cross-sectional view of the base fabric (B), Figure 2 is an explanatory diagram (A) of the method of applying vinyl chloride resin or urethane 41M resin to the surface of the glove being sewn over the aluminum glove mold. FIG. 3 is a diagram (B) showing a cross-sectional structure of a glove coated with vinyl chloride resin or urethane resin, and FIG. 3 is a partially cutaway perspective view of a finished product of the winter glove according to the present invention.

In the figure, reference numeral 1 indicates the stockinette-knitted base fabrics on both sides of the urethane resin foam layer 2, which is made by slicing urethane resin foam into sheets and pasting stockinette-knitted base fabrics on both sides. The thickness is 1.5~5
A thickness of mm is preferable, and nylon is the material for the base fabric 1 of stockinette knitting.

Ester, kotton, sufu, etc. are used. here,
The reason why the thickness of the urethane resin foam layer is preferably 1.5 to 5 mm is that if it is less than 1.5 mm, the heat retention effect will be poor.
Moreover, if it exceeds 5 mm, the sense of gripping an object becomes dull, which is not preferable. 3 is an aluminum glove that can be covered with a glove as shown in FIG. 1 (A), which was completed by cutting and sewing the urethane resin foam layer 2 described above and having the base fabric 1 on both sides in order to facilitate the process described later. It is a mold. 4-
is a vinyl chloride plastisol or urethane resin emulsion that is applied to the surface of gloves set in an aluminum glove mold. 5 is a layer of vinyl chloride resin or urethane resin formed on the surface of the glove coated with vinyl chloride resin or urethane resin, and this layer 5 of vinyl chloride resin or urethane resin is coated with vinyl chloride plastisol or urethane resin on the surface of the glove. It is obtained by applying a resin emulsion and heat-treating it.

Next, the method for manufacturing cold protection gloves according to the present invention will be further explained with reference to Examples.

Example 1 (]) A stockinette knitted base fabric made of cotton having a 4-thick urethane resin foam layer made by slicing urethane resin foam into sheets and pasting stockinette knitted base fabric on both sides was cut. A glove as shown in FIG. 1(A) is obtained by sewing.

(2) Place the sewn glove on the aluminum glove mold.

(3) Apply vinyl chloride plastisol with the following ingredients to the surface of the gloves.

Cover with vinyl chloride plastisol component (parts by weight).

(3) Apply a urethane resin emulsion containing the following ingredients to the surface of the glove.

(4) The gloves coated with the urethane resin emulsion were heat treated under the following conditions to form a urethane resin on the surface of the urethane resin foam, and removed from the aluminum back mold to obtain cold protection gloves as shown in FIG.

Heat treatment conditions Heating Pre-drying 100°C to 120°C/10 minutes to 20 minutes Main drying 150°C/10 minutes to 20 minutes Cooling The cold-protective gloves and the manufacturing method thereof according to the present invention as detailed above have the following effects. It is of great practical and industrial value.

As cold protection gloves.

(1) Since the inside is made of stockinette-knitted base fabric, it feels excellent when inserted into gloves.

(2) It has a urethane foam layer on the outside of the base fabric, so it has excellent heat retention.

(3) Since the surface is covered with a layer of vinyl chloride resin or urethane resin, it has excellent waterproof properties. Especially when the surface is made of urethane resin, both the surfaces of the foam layer 9 are made of urethane resin, so it can withstand low temperatures. To be able to be used in a variety of fields because it has little decrease in flexibility, is strong, and has excellent oil resistance.

(4) Since the foam layer is made of urethane resin, unlike the case of vinyl chloride resin, there is no bad odor caused by plasticizers, so it can be used for cooking purposes.

(5) Furthermore, by increasing the thickness of the urethane resin foam layer, it can also be used as anti-vibration gloves when using a chain saw or rock press.

(6) It is possible to design a deep uneven pattern (imprint to prevent slippage) on the outer skin of the glove.

As for the manufacturing method.

(1) Since the inner glove and outer glove are not glued together as in the conventional method, the working environment during bonding can be reduced.

(2) Since the outer surface has a knitted base fabric, there is no need to provide a sealing layer when forming the resin layer on the outermost layer, so the process can be shortened.
