ABSTRACT:
Artificial leather having a crepe pattern is produced by a process comprising preparing a base cloth material at least a part of which is composed of highly heat shrinkable yarn and less heat shrinkable yarn, said highly heat shrinkable yarn having a heat shrinkage rate of at least 10 percent at a temperature within the range at 80.degree. to 230.degree.C and the difference in the heat shrinkage rate between said highly heat shrinkable yarn and said less heat shrinkable yarn being at least 5 percent within the same temperature range, forming a synthetic resin film layer on said base cloth material to obtain an artificial leather material having a smooth synthetic resin surface, and subjecting said artificial leather material to a heat treatment to form a crepe pattern on said synthetic resin film layer due to the heat shrinkage difference between said highly heat shrinkable yarn and said less heat shrinkable yarn of said part of said base cloth material.
