Abstract

The present disclosure is relates to an environmental-friendly artificial leather and a method of manufacturing the same. The manufacturing method of the environmental-friendly artificial leather includes steps in which a first fiber web is formed by meltblown. The method continues with step in which a filament fabric is disposed on the first fiber web. The method continues with step in which a second fiber web is meltblown on the filament fabric, so as to form a multilayer fiber structure. The method continues with step in which the multilayer fiber structure is heat pressed to form the environmental-friendly artificial leather.
