Evaluation and Improvement of the Blowing-carding Effect
In order to reasonably control the quality of spinning semi-finished products and im-prove the yarn quality,the purpose,methods and standards for the blowing-carding effect evalu-ation are introduced in detail.Based on practical production experience and Uster bulletin data,the evaluation focuses on the blowing-carding effect of neps,impurity,short fiber,and fiber straightness for semi-finished products,the problems and causes are analyzed.Improvement methods are proposed for key processes and parts such as carding and blowing-carding.It is pointed out that the evaluation and improvement of the blowing-carding effect should be based on the variation patterns of impurity,short fiber,and straightness of semi-finished products.It is necessary to analyze and judge the blowing-carding effect of each process in the blowing-car-ding unit,analyze specific problems in combination with the distribution of cotton waste rate and noil rate,timely adjust non-compliant processes and parts,and give full play to the roles of accessories and parts.
