PURPOSE: To obtain an artificial fur closely resembling a seal or chinchilla as a fur of the highest quality.
CONSTITUTION: In this downy raised fabric with the raised fibers consisting of polyester fibers, it is characteristic that the raised fibers consist of at least two kinds of combined filament yarns including high-shrinkage yarns consisting of a copolymerized polyester and low-shrinkage yarns consisting of a non- copolymerized polyester, the boiling water shrinkage difference between the high-shrinkage and low-shrinkage yarns is 5-15%, the 160°C dry heat shrinkage difference between the high-shrinkage and low-shrinkage yarns is 15-40%, and the number of the raised fibers of the high-shrinkage and low-shrinkage yarns respectively account for ≥15% of the total number of the raised fibers. This downy raised fabric is obtained by the following process: the raised surface of a raised fabric is imparted with an alkali treating agent 150-700 poise in viscosity at a level of 10-300g/m2 followed by heat treatment to subject the tips of the raised fibers to caustic reduction.
