Abstract:In order to reduce the breakage of extra fine yarn and improve the spinning quality，the cotton distribution requirements such as good elasticity and gripping and spinning process of extra fine yarn are expounded，and the characteristics such as good elasticity and gripping and the matters needing attention in use of the high elasticity and low hardness cots are analyzed.Taking J-463A cot as an example，main points of the process of covering and grounding are introduced.By comparing the width of gripping line formed by cots with different hardness and rollers under different pressure，and yarn index of spinning C 4.16 tex，it is illustrated that J-463A cots have low hardness，high elasticity，non-treatment，strong ability to hold and control fibers，good yarn evenness and stable yarn quality.It is pointed out that choosing cots is the key to spinning extra fine yarns well，and making，using，managing and maintaining cots well will help to reduce spinning breakage and stabilize spinning quality. 
Key Words:cots；J-463A type；extra fine yarn；low hardness；high elasticity；grounding；covering；roller
