The present invention described 16f have super thick denier FDY of light to stretch full the production method of fiber, it is with glossy polyester melt
For raw material, melt cooler is entered by smelt spout Jing after booster pump supercharging, using melt cooler by melt cooling after,
Spinning manifold is sent into, Jing after metering pump-metered, then is extruded after being filtered by the filament spinning component in spinning manifold, spinneret is through brand-new
Design, the distribution in hole are more beneficial for uniformly penetrating for cross air blasting, then continue to supplement cooling by path, wind oil tanker and oil, in advance
After first, second, third, fourth hot-rolling drawing and setting of Network device, then through master network device, increase the obvolvent performance of fiber, most
By winding head package.
In the present invention, path is continued the path of cooling and is arranged on the wind end off the net of cross air blowing device until winding cruise,
Path is the interface channel of spinning and winding cruise.It is have super thick denier FDY of light to draw entirely specifically for production 16f that cooling is continued in path
Stretch designed by fiber, because the series of products filament number is more than 15dtex, belong to super thick denier product, by the side of conventional equipment
Quenching technique cannot complete sufficiently cool, and temperature of the fiber in path still compares high, so in order to improve
Low-fiber temperature, drops in cooling effect, and we use the run time fiber in path, and cooling wind is guided to path
Outside, designs equally distributed exhaust vent on the wall of path, is so introduced through cooling exhaust vent of the wind just from the wall of path for coming and blows
To tow, the effect for continuing cooling is served.The cold effect for serving and supplementing cooling fiber, reduce fiber temperature is continued in path,
Very crucial effect is served in the present invention.
Beneficial effects of the present invention are embodied in：The present invention relies on existing equipment platform, by process modification, innovation, produces
With compared with high-tech difficulty, compared with the new varieties of high product added value, the light FDY that has of present invention production stretches super thick denier product entirely
Filament number more than 15dtex, the kind of this specification, with conventional equipment production be with very high technical difficulty, so
The invention substantially increases the competitiveness of enterprise.
