Abstract
Described herein is a quenching system comprising a spinneret to spin molten polymer, a quench stack disposed operatively below the spinneret and the flow communication with the spinneret, a first means to provide a first stream of ambient air to provide partially-quenched solidified fibers of the molten polymer spun through the spinneret, at a solidification temperature and a second means to provide a second stream of conditioned air at a below-ambient temperature for further quenching the partially quenched solidified fibers, wherein the second stream of the conditioned air is provided through an adapter placed operatively below a region where the molten polymer solidifies partially.
