Abstract:In order to spin slub yarn with larger slub multiple and longer slub length using extended top cradles on ring spinning frame，taking combed cotton 27.12 tex slub yarn as an example，the setting and adjustment measures of the main process parameters of blowing-carding，cotton pre-drawing，drawing and lap combined，combing，drawing，roving and spinning processes are analyzed by introducing the cotton assorting situation and process. It is pointed out that when combed cotton 27.12 tex slub yarn is spun in the FA502 spinning frame equipped with slub yarn device and using extended top cradle，Zhaodong lower pin and V-type drafting device，smooth drafting should be ensured to prevent“hard head”and“big belly yarn”in the section.In the spinning process，slightly larger roller gauge and drafting multiple of the rear-zone，appropriate roller nip spacer，moderately larger pressure of the rollers，appropriate ring and suitable low speed of the front rollers should be adopted；while in the automatic winding process，lower winding speed and appropriate electric cleaning process should be adopted.
Key Words:extended top cradle；combed cotton；slub yarn；slub multiple；slub length；roller gauge；drafting multiple；winding
