Through continuous improvement and technological innovation, ring spinning technology has kept the leading position during the harmoniously developing of all kinds of spinning technologies. Compact spinning technology and composite spinning technology have not only remarkably improved ring spun yarn grade, but also broadened its application scope, which is the new development and innovation of ring spinning technology. Adoption of long ring spinning frame with automatic doffer and spinning-winding unit is another developing tendency of ring spinning technology. It’s the key point to achieve quality, high efficiency and better profit to match the accessories while the mainframe selection is the fundamental work.
