Applications:
With multi-stage drawing and thermal setting process, the machine is suitable for production of high tenacity, low shrinkage polyester industrial yarn in melt spinning.
Features:
●Specially designed extruders improves melt properties and reduces melt viscosity degradation.
●Top mounted spinneret of high pressure self sealing with 200mm in dia. is applied.
●Individually temperature controlled stage heater is used to effectively prevent sheath-core fiber structure formation.
●Different configurations of multi-drawing and thermal settings are used to meet different requirements of industrial yarn.
●Hot godet is induction heated and thermal tubes and sectional temperature control are applied to get better uniformity of surface temperature in the working zones.
●BWA-G type winders of Beijing Chonglee are used to achieve low ADF, low waste rate and good package formation.
