Spinning of Super Fine Yarn under 2.9 tex on the Material and the Accessories

Through the analysis of the condition and the product for the spinning of the super fine cotton yarn,introduction is put forth to the fibre performance and the mechanical index of the super fine yarn on the basis of the analysis of the condition of fibre varieties and the fibre development.Analysis is done to the problems resulting from the current spinning frames,accessories,and the spinning theory and the solution is given herewith.Conclusion is made that mass production of the super fine yarn is dependable on the improvement of the reproduction and processing of the cotton with super long fibre.The on-going spinning frame and the accessories plus the process are not qualified for production of cotton yarn under 1.9 tex.It is necessary to make an approach into the synthetization technology of multi-spinng theory with tech-modification of the frame and the accessories.The endless end break in the spinning area and the auto winding area,say,the end break resulting from the limit of the least strength,is much related with the strength of the super fine yarn,and more it is necessary to reduce the friction of the cotton yarn in the process of spinning.
