Abstract:
A yarn-forming filament cooling apparatus comprising: a stand-up air-compartment defining a cooling air channel and having an air inlet at a lateral side, an air outlet at a front side, and a plurality of filament guiding posts at a top thereof; and a quick-cooling air-coverage compartment located above said cooling air channel of said stand-up air compartment and including a plurality of axially extended inner tubes corresponding to said filament guiding posts, each of said inner tubes being provided with a plurality of throttle pores on a circumferential surface of said inner tubes, for external air to enter into said inner tubes; whereby when filaments for forming yarns are directed to pass said filament guiding ports and enter into said inner tubes, air flowing through said cooling air channel is radially drawn into said inner tubes to evenly cool said filaments in all directions.
