Waterproofing.

전투화에 사용되는 중창은 빳빳해야 하므로 침지하여 방수처리한다. 그리고 EVA 필름을 사용하는 이유는 일반적인 필름은 본드접착을 해야 하므로 인체에 유해하나, EVA는 본드를 사용하지 않고 융착이나 열만 가하면 되므로 자연친화적이다. 그리고 본발명에서 하부층은 얇고 상부층은 수분흡수가 용이하게 두껍게 제작한다. 그 두께는 하부부직포는 1mm, 중간필름은 0.4mm, 상부부직포는 1.5 mm정도이다. 본중창을 하부의 미드솔과 본드로 결합한다.     The midsole used for combat boots should be 빳빳 so immersed and waterproofed. And the reason for using EVA film is that it is harmful to the human body because the general film should be bonded, but EVA is natural because it only needs to be fused or heat without using a bond. And in the present invention, the lower layer is thin and the upper layer is made thick to easily absorb moisture. Its thickness is 1mm for the lower nonwoven fabric, 0.4mm for the intermediate film, and 1.5mm for the upper nonwoven fabric. Bond the midsole to the lower midsole with a bond.
