| Abstract: | The importance of inherent quality evenness of polyester tow is studied. The main factors to influence the quality evenness during the spinning are analyzed. The scheme of process optimization of spinning temperature, quench air velocity, initial pressure of spin pack and spinning speed etc is put forward. The process parameters of spinning temperature 288 ℃, quench air velocity 3.3 m/s, initial pressure of spin pack 10.5~11.0 MPa and life time of spin pack 30 days are selectes. The uneveness of breaking strength, breaking elongation, titer and cross section are lower. |
