Abstract:In order to improve yarn quality and cloth surface quality，the characteristics of the extended top cradle，and the comparison of yarn quality indexes of spinning semi-combing C 18.2 tex yarn，elastic 36.4 tex+70 D yarn and commpact spinning CJ 14.5 tex yarn with the extended top cradle and other top cradle are introduced.The matters needing attention and technical management measures of using extended top cradle are expounded.It is pointed out that the extended top cradle has good wear resistance，rigidity and antistatic properties，long service life，and is not easy to deform and adsorb flying flowers.The extended top cradle is suitable for spinning carded yarns，carded special yarns and fine yarns，and can improve yarn quality.The process parameters should be optimized according to the spinning variety，and the maintenance and dynamic maintenance of the equipment and the cleaning management of the drafting floating area should be strengthened when using the extended top cradle.
