Influences of Process and Equipment on Filament Unevenness

Abstract:

The yarn irregularity of polyester POY in melt spinning influences not only the follow-up spinning property, but also the dyeing performance. The yarn irregularity is caused mainly by unstable state during which the filament is formed. It is presented in this paper that the main factors which affect the filament unevenness in melt spinning. They are the quality of raw materials, the improper choice and fluctuation of technological parameters, the structure of equipments and running conditions, etc. Such factors as steady spinning temperature, quenching conditions, the high performance finishes, proper collection oiling point and correct operation will guarantee lower filament unevenness.
