ABSTRACT:
In a non-friction texturing process, the filaments of a thermoplastic polymer yarn are heated along spaced zones to form latent crimps in the filaments. The filaments are then drawn and are subsequently heated above the glass transition temperature of the polymer while the filaments are under low enough tension to allow crimps to form in the filaments. The heating along spaced zones is preferably accomplished by passing the filaments over a grooved heating roller.
