Abstract
In order to control blending ratio and blending ratio unevenness,improving the drafting blending effect of drawing sliver,starting from the basic principle of sliver blending,taking the direct blending of two component fibers as example,the estimation formulas of theoretical blending ratio unevenness and theoretical weight unevenness of the drawing sliver were derived through statistical derivation and example calculation.The calculation and statistical control methods of blending ratio and its unevenness were illustrated.Specific measures to improve blending ratio and yarn evenness were analyzed and explained from the aspects of raw material optimization,process route,process parameter,equipment,operation and management.The results showed that on the basis of ensuring the quality of input slivers,the unevenness of output sliver blending ratio can be effectively reduced by appropriately increasing doubling sliver number,increasing the doubling times,reducing the unevenness of input slivers with small blending ratio,and controlling the input blending ratio within a reasonable fluctuation range.It is believed that applying the theoretical calculation formula in the actual production work will take a good guiding role in controlling blending ratio and its unevenness in sliver blending process.关键词
