Definitions

• the present invention relates to an insole of shoe made of coconut and its manufacturing method, whose a natural vegetable fiber, which is coconut textile, is made into a short strand and manufacture this, so that it makes an insole of shoe that air permeability, cushion strength and tension is excellent by forming a board, which has a regular thickness.
• the outsole of shoe is a part contacted with a foot directly, so it should be made for comfort minimizing the fatigue with a long-time walk.
• each strand of coconut textile is formed as coil-shaped, they are pieced together in a mold, then an undiluted solution of natural latex is sprayed and dried. After that, it is pressed by heat and manufactured as a regular board-form, so that each strand of coiled textile is tangled with one another, so that insole, whose air permeability, cushion strength and tension is excellent, can be provided.
• the present invention relates to an insole, which is after the coconut textile is formed like a wad of cotton, an undiluted solution of natural latex is sprayed and dried, and then it is pressed by heat and formed an insole as a shape of the sole of ones foot .
• FIG. 1 is a perspective view of a tangled state according to a manufacturing method of the present invention
• FIG. 2 is a cross sectional view that a natural fiber is attached on the board of the present invention
• a natural fiber textile layer (3) is formed on the said adhesive layer (2) , so that the insole can has a smooth surface.
• This natural fiber textile layer (3) is used because of the excellence of the air permeability and absorptive property in various choices of textiles.
• this coconut board which is used for the insole of a shoe is following; coconut pulverization for gathering the coconut fiber at the first level; selecting only the coconut fiber among the pulverized coconut at the second level; at the third level, the each selected fiber is twisted into a bundle in order to make the fiber as a coil form; as the forth level, the bundle, which is consisted of twisted fiber strands is heat-treated by steam. At this point, the temperature of heat is appropriate as 70-100°C centigrade and when it is lower than 70-100°C, the twisted strands is to be untwisted, or when it is higher than 70-100 ° C, the energy is wasted and the fiber is deformed.
• coconut fiber is straight, so even if fiber layers are piled and produced as a board, the cushion strength can not be great and considering the fiber is maximum 20cm, the cushion strength is not good, so theses third and forth level are another method of manufacturing.
• cooling and ripening stage in order that twisted formation of the said twisted fiber strands, which is heat-treated by steam, may be maintained;
• dismantling stage that is each fiber strands, which is twisted and ripen, is untwisted individually in order that each fiber strands may be formed as coil;
• each dismantled fiber strands, which is formed as coil is made flat in a regular thickness;
• the eighth level that is natural latex undiluted solution is sprayed and dried on the textile, which is made flat in a regular thickness;
• the temperature is most appropriate as 70 ° C- 100 ° C centigrade, which is a degree that the natural latex undiluted solution is not dried completely and
• the textile which is covered the above heat-treated latex undiluted solution, is compressed in an appropriate thickness, so that it can have the regular thickness and bring a surface to a level; at this moment, the temperature is most favorable as 180-200°C centigrade for the heat- press, and if the temperature is lower than the 180-200°C centigrade, the strands of textile, which is formed as board, may be exposed and if the temperature is higher than the 180-200 °C centigrade, the surface may become solid.
• this manufactured material is proceeded in a cooling stage as the eleventh level in order to retain its original form made by pressure.
• coconut board (1) manufactured as this procedure is cut compatibly with the insole form; and the insole form is attached cotton fabric or applied the latex undiluted solution on the surface, so that the surface can be smooth. All kind of coconut fiber can be used at this point, however, if the only long fiber is used in the above level of selecting fiber, it is easy to twist fiber and the elasticity as well as tension is great, even when it is formed as a board.
• the level of spraying mud powder is included between the eighth spraying level that the latex undiluted solution is sprayed and the ninth heat-treatment level, so that the mud powder infiltrates into the fiber tissue, which is very effective for foot-care in the regard of resolving the stink of foot, promoting blood circulation and antibiosis effect with a unique enzyme.
• the amount of the mud powder, which is sprayed on the coconut textile is not fixed, but it is inserted into the crevice among the fiber, which is formed like a wad of cotton and sprayed on the surface of the textile, then the efficacy can be maximized the moment some crevice is maintained among the fiber.
• the mud powder contains Catalyser, Dipenol Oxidase and Proteinase, which come into effect for the human body, so that it has a great efficacy to relieve fatigue by neutralizing or absorbing Lipid Peroxide, which cause the skin to age, and it is well-known for activating the physiology of human body and promoting blood circulation, as well we resolving excretive organs and stink, deodorizing, antibiotic function and relieving the pain due to radiating a great amount of far infrared.
• the insole of shoe of the present invention is very good for air circulation and cushion strength, because the coconut textile is formed as a wad of cotton, which has a lot of gaps among the fibrous tissue, also coconut and the latex undiluted solution are all natural, so absorbing function is excellent.
• the heat-treatment level makes enough for sterilization and antibacterial function, so that it is very hygienic and easy to dry after washing.
