본 고안은 구두갑피의 원형을 지속적으로 유지시키며 갑피와 신발밑창을 견고하게 결착시켜주는 착화감이 우수한 신발중창에 관한 것이다.The present invention relates to a shoe midsole with excellent comfort to maintain the original shape of the upper of the shoe and to firmly fix the upper and the sole of the shoe.
원래 신발중창은 사람의 체중을 지탱할 수 있어야 하며 관련 구성되어지는 갑피, 신발밑창등과 접착력이 우수해야 하고 땀, 습기, 물등에 의하여 파손되거나 조직이 와해되어 빳빳한 성질(Stiffness)을 상실해지는 않된다.Original midsoles must be able to support the weight of the person, must have good adhesion with the upper, soles, etc. that are involved, and must not lose their stiffness due to breakage or tissue damage due to sweat, moisture, or water. .
종래 신발중창은 합성수지 또는 접착성물질에 함침시킨 부직포이거나 판지로 구성시킨 중창이 있으나 지지력이 부족하고 땀, 습기 및 물등에 의하여 자체의 조직 즉 부직포나 판지중창을 구성하는 섬유를 접착결속하는 접착제가 용해되어 조직간에 접착력이 떨어지고 치밀성을 상실하게 되므로서 조직이 와해되어 지지력을 상실하게 되고 따라서 초기의 신발원형을 유지할 수 없게 됨은 물론 신발수명 또한 짧아지게 된다.Conventional shoe midsoles are non-woven fabrics or paperboard midsoles impregnated with synthetic resins or adhesives, but lack of support and adhesives that bond the fibers that make up their tissues, such as sweat, moisture, and water, to bond their fibers. Dissolution results in loss of adhesion between tissues and loss of compactness, resulting in tissue breakdown and loss of support, thus preventing the initial shoe circle, as well as shortening shoe life.
그밖에도 종래의 신발중창으로 폴리에치렌 또는 폴리푸로피렌쉬트로된 단일기재나 이 기재위에 연질비닐쉬트 또는 합성수지 저발포쉬트등으로 적층시킨 신발중창은 중창자체의 원형은 지속적으로 유지될 수 있으나 이를 구성하는 폴리에치렌이나 폴리푸로피렌 양쪽 공히 접착성이 극히 불량하여 천연피혁이나 합피로 구성된 갑피와 천연고무 또는 합성고무로 구성한 신발밑창과의 접착력이 불량하여 큰 문제점으로 지적되고 있다.In addition, a shoe sole laminated with a single substrate made of polyethylene or polyfluoropyrene sheet or a soft vinyl sheet or a synthetic resin low foam sheet on the substrate may be maintained in its original shape. It is pointed out as a big problem because the adhesion between both ethylene and polypropylene is extremely poor, and the adhesion between the upper made of natural leather or leather and the sole of shoe made of natural or synthetic rubber is poor.
본 고안에 의한 신발중창은 자체원형을 지속적으로 유지할 수 있고 갑피 및 신발밑창과의 접착력을 향상시킨 중창으로서 이를 도면에 의하여 설명하면 폴리푸로피렌 또는 폴리에치랜 쉬트(1) 양면에 폴리에스텔 파이바(2)를 균일하게 박막으로 분포시켜 열융착하므로서 폴리에스텔파이바 박막층(3)을 형성한 쉬트 일측에 저발포 연질 폴리우레탄 쉬트(4)를 접착시켜 재단한 신발중창에 관한 것이다.The midsole according to the present invention is a midsole that can maintain its own circular shape and improves adhesion to upper and shoe soles. The invention relates to a shoe sole made by bonding a low-foaming soft polyurethane sheet (4) to one side of a sheet on which the polyester fiber thin film layer (3) is formed by uniformly distributing (2) into a thin film and thermally fusion bonding.
본 고안에 있어서 폴리푸로피렌 또는 폴리에치렌 쉬트의 두께는 1-2mm정도이고 박막의 폴리에스텔 파이바층은 일반 휴지정도의 두께가 가장적합하며 이와같은 박막의 폴리에스텔파이바층을 열융착시키므로서 상기 합성수지재질의 온도변화에 따른 신축변형을 방지할 수 있고 신발중창을 구성하기 위하여 적층되는 타재질과의 접착성은 물론 갑피 및 밑창과의 접착성을 크게 향상시킬 수 있다.In the present invention, the thickness of the polypropylene or polyethylene sheet is about 1-2 mm, and the thickness of the polyester fiber layer of the thin film is most suitable for the general degree of rest, and the heat-sealing of the polyester fiber layer of such a thin film The elastic deformation due to the temperature change of the synthetic resin material can be prevented, and the adhesion with the upper material and the sole as well as the adhesion with other materials laminated to form the shoe sole can be greatly improved.
그 이유로는 폴리에스텔파이바는 연화온도 및 용융온도가 높기 때문에 용융되지 않은 상태로 열융착에 의하여 폴리에치렌이나 폴리푸로피렌쉬트의 조직에 견고하게 결착되며 표면의 폴리에스텔 파이바 박막층은 폴리에치렌이나 폴리푸로피렌에 비하여 접착력이 월등하므로 결국 폴리에스텔 파이바 박막층이 합성수지재질의 열변형을 방지하고 강력한 접착력을 갖게 하는 가교역활을 하게 되는 것이다.Because of the high softening temperature and melting temperature, polyester fiber is hardly bonded to the structure of poly ethylene or polyfluoropyrene sheet by heat fusion in the unmelted state, and the surface of polyester fiber thin film is Since the adhesive strength is superior to that of styrene or polypropylene, the polyester fiber thin film layer serves as a crosslinking agent to prevent thermal deformation of the synthetic resin material and to have strong adhesive force.
