ARTIFICIAL LEATHER INCLUDING WATERBORNE POLYURETHANE FOAM LAYER AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to artificial leather including a waterborne polyurethane foam layer, wherein the a waterborne polyurethane foam layer having an open cell is applied to artificial leather used for manufacture of a vehicle sheet through mechanical foaming, whereby the artificial leather can provide a sense of cushioning and excellent water vapor permeability and can reduce the temperature of the surface of a sheet in summer, and when applied to a vehicle sheet, the artificial leather can prevent the formation of fold wrinkles in the vehicle sheet. For implementing this, the present invention comprises: a fabric layer (110); a binder layer (111) laminated on the fabric layer (110); a waterborne polyurethane foam layer (120) laminated above the fabric layer (110); a skin layer (130) laminated on the waterborne polyurethane foam layer (120); and a surface treatment layer (140) laminated on the skin layer (130), wherein The waterborne polyurethane foam layer (120) has an open cell formed through mechanical foaming.
