Quality identification method of flowering machine

     The quality of the flowering machine is specifically reflected in the quality indicators and falling objects of the semi-product (fiber roll or fiber layer) after opening. This includes:

①The type and quantity of impurities and defects in the semi-finished product;

②Structure and uniformity of semi-finished products;

③The content of short fibers in semi-finished products;

④The opening degree of the fiber block is expressed by the average weight of the fiber block (g/block), the unit volume weight (kg/m3) or the final speed of the free settlement of the fiber block in the air;

⑤ The drop contains the number of spinnable fibers.

     In order to further improve the opening quality of fiber raw materials and the quality of yarns, the main development direction of the opening process is to improve the form and structure of the flowering machine parts, and widely use carding machines such as licker rollers, needle beaters or needle drums. , Improve the opening degree of the fiber block, improve the structure and uniformity of the semi-product; Strengthen the pre-opening of the fiber raw materials, in the opening process, use more free blows, and try to use less gripping blows; use airflow and other openings The impurity removal method avoids fiber damage and impurity fragmentation to reduce the resulting yarn defects.
