Abstract:In order to reduce the sudden long thin places defects，six cases of sudden long thin places defects in drawing,roving and spinning process are analyzed in detail. The cases include the irregular long thin places defects caused by condenser suctioning the sliver，the abnormal Cm/CCm yarn defects caused by severe mechanical waves，the unexpected drafting caused by poor operation of back cots in roving，the regular thin places caused by wear of the keyway and key of the back roller head in roving，the frequent splitting of slivers on the roving overhead and the thin slivers caused by the roving stop feeding device colliding with the back cots，etc.The causes of the problems are explored and solutions are proposed.The results show that the long thin places defects are comprehensive reflection of various basic spinning tasks.According to the specific causes of different yarn defects，scientific operation methods should be formulated，and equipment problems should be corrected in time to make long thin places defects disappear.Resolving long thin places defects is a systematic work，so we should carry out more activities to catch and prevent defects，and deal with abnormalities in time in daily life.
