Abstract

La présente invention concerne une composition de mousse pour une semelle intérieure fonctionnelle et un procédé de fabrication d'une semelle intérieure fonctionnelle multicouche non adhésive l'utilisant. Dans une composition de mousse pour une semelle intérieure fonctionnelle et un procédé de fabrication d'une semelle intérieure fonctionnelle multicouche non adhésive l'utilisant selon la présente invention, un processus d'adhérence est omis. Par conséquent, la présente invention peut améliorer un travail nocif, éliminer une substance nocive à l'intérieur d'une semelle intérieure, améliorer une propriété physique, raccourcir le processus de fabrication, améliorer la productivité et réduire les coûts de fabrication.
