ABSTRACT:
A system for preparing a composite crimped filament (2) using a nipping type false-twisting apparatus (7) which has two endless intercrossing belts (13), (16) whose working surfaces are urged against each other in their intercrossing region (17) to nip the filament yarns (2) therebetween. A liquid is applied to the yarns (2) upstream of the false twister (7) to reduce friction and heat.
