Method and apparatus for cooling molten filaments in spinning apparatus.

摘要

A method for cooling molten filaments in a spinning apparatus where, a plurality of molten filaments (2) extruded from a die (1) are cooled by cooling air blown out from a cooling apparatus (3) and are taken up with a draft, wherein the temperature and/or volume of the cooling air blown from the cooling apparatus is controlled so that the cooling is performed stronger, in stages or continuously, from upstream to downstream.
