| Abstract: | The process of polyester intermingled textured yarn with low-shrinkage by melt direct spinningwas analyzed systematically. The results showed that high-quality polyester ITY fiber with low-shrinkagecould be produced when oiling position of POY was higher than that of FDY, the control valve of doublequench air and two intermingling jets were designed, the GR2 hot roller was 7.5 turns and under some otheroptimal technology parameters. |
