Abstract

In manufacturing the insole from a resin sheet bonded with a napped fabric covering on a side, the resin sheet is composed of latex resin including a foaming agent and being coated in a certain thickness over a napped fabric sheet. The coated sheet is then semivulcanized to be cut into half-products, which are head- pressed for complete vulcanization to be formed into a certain shape of insole. The product shows an improved cushion, air permeability, and absorbancy for moisture and odor which are released into air upon taking off the shoes.

본 발명은 상품 특성이 극히 우수한 운동화류의 신발 안창의 제조 방법에 관한 것이다.The present invention relates to a method for producing shoe insoles of athletic shoes with extremely good product characteristics.

통상 인솔(insole)로 통칭되는 운동화류의 안창은 착화감촉을 양호하게 유지시키기 위하여 기모성 포지의 하면에 쿳션 감각이 양호한 발포성 합성수지 시이트를 접착한 구조로 되고, 이 합성수지 시이트는 주로 발포성 우레탄, EVA 수지, PE 수지 등으로 널리 이용되고 있으나 이들 수지재질은 쿳션 감촉은 양호하나 통기성이 불량하므로 신발속에 흡수되는 땀, 냄새등의 발수성, 통수성, 습기증발등이 미흡하여 오랜 시간 착화시 땀냄새가 많이나고, 무좀 발생률이 높은 등의 결점이 있었다.Insoles of sneakers, commonly referred to as insoles, have a structure in which a foamed synthetic resin sheet with good cushioning is adhered to the lower surface of the raised fabric in order to maintain a good ignition feel. The synthetic resin sheet is mainly foamed urethane and EVA. It is widely used in resins and PE resins, but these resin materials have good cushioning feel but poor breathability, so there is insufficient water repellency, water permeability, moisture evaporation, etc. There were many defects such as high rate of athlete's foot.

본 발명은 신발 안창의 시이트 재질로서 종래의 재질이 갖는 이상과 같은 결점을 개선하여 천연라텍 원액을 발포제의 첨가로서 통기성을 높이고, 그 조직의 발수효과(發水效果)를 높이므로서 신발 안창으로서 요구되는 땀냄새 제거와 습기발산효과를 높여 무좀예방과 위생 청결 유지에 뛰어난 효과를 나타내게 하면서 쿳션 감촉이 기존의 신발창보다 더욱 개선되게 한 것으로 이하 본 발명의 신발 안창의 제조 방법을 상세히 설명하면 다음과 같다.The present invention improves the above-mentioned shortcomings of conventional materials as a shoe insole sheet, and improves breathability by adding a natural latex solution as a foaming agent, and improves the water repellent effect of the tissue as a shoe insole. By removing the required sweat odor and moisture dissipation effect to show the excellent effect on athlete's foot prevention and hygiene cleanliness, the cushion texture is further improved than the existing shoe sole. Hereinafter, the manufacturing method of the shoe insole of the present invention will be described in detail as follows. same.

1 : 라텍스 수지시이트의 조성. 제1도는 본 발명 방법에 의하여 제조된 신발 안창의 예시도로서 상면은 통상의 기모성 포지(2)가 접착되고 하면은 발포성 안창 수지시이트(1)로 구성된다.1: Composition of latex resin sheet. 1 is an exemplary view of a shoe insole manufactured by the method of the present invention, the upper surface of which is coated with a conventional brushed forge 2 and the lower surface of which is made of a foamed insole resin sheet 1.

제3도는 본 발명 제조방법의 실시예도로서 회전드럼(6)에 기모성 포지 기지(其地)(1a)를 반대편의 권취드럼(7)에 연속적으로 이송시키되, 기지(1a)의 이송라인에 라텍스 수지공급통(3)을 설치한다. 라텍스 수지 공급통(3)에는 천연라텍스 수지액에 가류제 및 발포제를 적정량 용입하여 기지(1a)위에 나이프(4)에 의하여 일정한 두께로서 도포되게 하고, 기지위에 라텍스 수지(2a)가 도포된 후에는 가류실(5)을 통과 시킨다. 이 가류실은 가류 온도 150℃ 전후를 유지하여 기지(1a)의 이송 속도를 빠르게 조성하므로서 가류실(5)에서는 완전가류가 되지않고, 반가류 상태로서 권취드럼(7)쪽에 회수되게 한다.3 is an embodiment of the manufacturing method of the present invention to continuously convey the raised forage base (1a) to the winding drum (7) on the opposite side to the rotating drum (6), to the transfer line of the base (1a) Install the latex resin supply container (3). After injecting appropriate amount of vulcanizing agent and foaming agent into the natural latex resin liquid into the latex resin supply container 3 by the knife 4 on the base 1a, and applying the latex resin 2a on the base. Passes through the vulcanization chamber (5). The vulcanization chamber maintains around 150 ° C. of vulcanization temperature to rapidly form the conveying speed of the base 1a, so that it is not fully vulcanized in the vulcanization chamber 5, and is recovered to the winding drum 7 as a semi-vulcanized state.

2 : 재단공정. 권취드럼(7)에 회수된 라텍스 수지가 도포된 기지(1a)는 소정의 신발 안창의 규격으로 재단을 하여 반제품으로 한다.2: cutting process. The base 1a coated with the latex resin recovered on the winding drum 7 is cut to a predetermined size of a shoe insole to be a semi-finished product.

3 : 열프레싱 공정. 재단된 소재(10)는 제4도와 같이 열프레스(8)(9)의 사이에 내입하여 전기 1공정의 미가류 상태가 완전가류 상태가 되도록 가열가압 성형하여 제품을 완성한다.3: heat pressing process. The cut material 10 is interposed between the heat presses 8 and 9 as shown in FIG. 4, and heat-press molding to complete the product so that the unvulcanized state of the first step becomes a fully vulcanized state.

이상과 같이 제조되는 본 발명의 신발 안창은 기모성 포지(2)를 받쳐주는 시이트가 라텍스 원액을 소재로하고, 또한 발포와 함께 가류가 이루어져 그 쿳션 감촉이 기존 제품보다 양호하면서 기공 형성이 불규칙 배열로서 서로 연결된 상태로 되어 미세기공이 형성되어 통기성이 아주 좋으므로 신발 안창으로서 사용할시 발의 수분과 땀냄새를 잘 흡수하고, 흡수된 땀냄새와 수분은 신발을 벗어들시 대기중에 원활히 방출하여 그 발수효과가 뛰어난다.In the shoe insole of the present invention manufactured as described above, the sheet supporting the raised forge 2 is made of a latex stock solution, and is vulcanized together with foaming so that the cushion texture is better than that of the existing products, and the pore formation is irregularly arranged. As it is connected to each other, fine pores are formed and breathability is very good. So, when used as shoe insoles, it absorbs moisture and sweat smell of the foot well. Excellent effect.

따라서 본 발명에 의해 제조되는 신발 안창은 착화감의 개선, 땀 흡수 및 발냄새 제거 효과가 양호하여 신발 상품의 고급화와 착화시의 위생청결 유지에 현저한 상품적 특성을 가진다.Therefore, the shoe insole produced by the present invention has a good product characteristics to improve the feeling of ignition, sweat absorption and foot odor removal effect to maintain high-quality shoes and hygiene cleanliness during ignition.
