Process for making high simulation ultra-fine fabric leather based cloth

One high simulation superfine fiber leather base cloth production method, uses the double component altogether to mix spinning production law produce island superfine fiber, then makes the adhesive-bonded base cloth material, first contains soaks half polyether polyurethane resin or the polyester polyurethane resin, then blows in base cloth the surface spreads gathers the carbonic ether polyurethane resin or the entire polyether polyurethane resin, then carries on coagulation processing using the DMF solution after the polyurethane resin, then uses the lukewarm water completely to wash DMF, use toluene solution island superfine fiber's in 'sea' ingredient extract comes out, then carries on alkali decrement processing. This invention produce base cloth which has thickness direction from trapezoidal density distribution structure, the dermis feeling is strong, may further enhance the artificial leather product the scale.
