Abstract The influence of carding machine cylinder and licker-in linear speed ratio on yarn strength was discussed.Licker-in speed was adjusted at 600 r/min，700 r/min，800 r/min and 900 r/min，the yarn strength comparison tests were carried out when the linear speed ratio was 1.5，2.0 and 2.5 respectively.The results showed that yarn strength was better when licker-in speed is 600 r/min and the linear speed ratio is 2.0.Larger cylinder and licker-in linear speed ratio was beneficial to improve yarn strength.It is considered that the yarn strength is better when the cylinder and licker-in linear speed ratio is 2.0，considering other factors affecting the yarn quality ，licker-in speed is suitable in 800 r/min~900 r/min.
