Title: Method for cooling melt-spun polyamide filament yarn
Inventor: MATSUMOTO NORIRO
IPC: D01F6/60
Filed: 1993-12-24
Abstract: PURPOSE:To provide a method for cooling high-speed melt-spun ultra-fine polyamide filament yarn, designed to stabilize traveling of the yarn portion just under the spinneret to reduce the effects of yarn fluctuation to inhibit developing yarn unevennesses or mutual yarn sticking, leading to operability improvement. CONSTITUTION:Hot air heated to >=50 deg.C through a heater 2 set up above a cooling air duct 1 is blown, through the hot air blow port 5 of a blower 3, on a filament yarn Y just under the spinneret following melt spinning of nylon 6, and discharged via an exhaust duct 4 so as not to raise the temperature of the cooling air flowing thereunder. Subsequently, cooling air from a cooling air duct 1 is blown, via the cooling air blow port 6 located under the hot air blow port 5, on the filament yarn Y. The hot air blowing on the filament yarn Y prior to the cooling shifts the solidifying point of the filament yarn Y to a lower level along with applying a moderate tension thereon, thus preventing yarn fluctuation due to the concomitant air flow generated in consequence of the solidification of the filament yarn Y.
