| Abstract: | The fine denier PET preoriented yarn(POY) of 266 dtex/288 f was prepared by using a single spinneret with a circular air blow unit transformed from a cross air blow unit.The effect of the spinning conditions on the physical properties of POY was studied.The results showed that the PET POY with superior properties can be produced by controlling the spinning temperature 290-293℃,circular air pressure 130 Pa,spinning speed 2 700 m/min.The obtained POY had the yarn irregularity of 1.1%and the unevenness of breaking strength and elongation at break below 3.0%and 4.0%,respectively. |
