THE PREPARATION OF POLYAMID FILM

摘要

The method includes the process of fabricating a sheet by extruding 80 or 98wt% nylon-6; or more than one species 2 or 20wt% other nylon and a mixture including a mineral crystalline germ agent whose isothermal crystallization rate parameter measured at 190deg.C is 1.2 or 2.3, and the process of biaxial orientation of the fabricated sheet.
