Partially Oriented Yarn

Polymer in the melted form from polycondensation section is cooled in polymer cooler, filtered and after pressure boosting it is distributed to the spinning manifolds and then to the spinning positions. The polyester melt from spinning position is extruded through spinnerets by variable speed driven spinning pumps. The extruded filaments are cooled by precisely controlled conditioned and filtered air in quench chamber. The filaments are then passed through the finish application system. The filaments are taken on take up winders and finally wound on bobbins. The yarn produced is extremely fine and the unit of fineness is denier. The spinnerets and spinning manifold are jacketed and heated with dowtherm vapour.
Technology
Yarns are produced by a continuous polymerisation process.
Strict quality control of denier orientation and spread, along with computer-controlled draw force testing, ensures maximum consistency of yarn performance during and after texturising.
All critical yarn proprietary such as draw force, tenacity, elongation, uster and shrinkage are closely monitored and controlled.
A special proprietary spin finish protects the colour and lubricity of the yarn over long periods of storage.
Controlled interlace in filaments as well as the special finish enable the yarns to be texturised at speeds of 750 mpm and above
