An Investigation on the Physical Properties of Textured Polyester Filaments.

The characteristics of five kind domestic polyester filaments have been examined with a variation of twist number and texturing temperature using FT type texturing machine. The results are as follows; 1. The concentration of dye absorption reached maximum at about 210$^{\circ}C$ of the heater temperature. 2. The necking state of textured yarns was not related with texturing conditions. 3. The fineness variations of textured yarns were increased tp 5.5∼9.4% than those of raw filament yarns, and were serious at 180$^{\circ}C$ of the heater temperature. 4. The frictional coefficient was decreased by the texturing process but there was no connection with heater temperature and twist numbers during texturing. 5. The Static electricity of textured yarns was not varied with the texturing conditions, twist numbers, and heater temperature, but static electricity was decreased slightly with the abrading numbers of yarn cohesion.
