| Abstract: | The production technology of polyester FDY through melt direct spinning was discussed. How to choose different process parameters to gain stable production and good quality was studied for different varieties of FDY. The result showed that through selecting melt inlet pressure of 5～10 MPa, spin beam temperature of 285～295℃, draw ratio between 2 7 and 3 0 and proper process parameters, the high\|quality FDY can be obtained. |
