ABSTRACT:
Yarns of melt-spun polymeric filaments are rapidly quenched, whereby the filaments are cooled by quenching gas that is accelerated along the threadline by being passed through a tube of reduced dimensions with the filaments before they emerge. In particular, a yarn is produced which has an elongation to break of about 100% or more. The yarn is comprised of filaments numbering from 25 to 150. The filaments are less than 4 denier per filament and makeup yarns having low denier spread.
