ABSTRACT:
A method and apparatus for improved quenching of nonwoven filaments utilizing a turbulence inducing bar arrangement disposed in a stream of quenching gas between the quenching gas supply apparatus and the group of filaments being extruded. The bar arrangement increases the turbulence of the quenching gas so that the gas applied to the filament group has a turbulence intensity of at least about 5%. The turbulent quenching gas penetrates the interior of the filament bundle to provide more efficient removal of heat.
