How to judge the quality of the opener?

The use of the opener is a process to loosen the compressed and entangled fiber raw materials and remove impurities. First, the raw materials need to be loosened, various impurities removed, and mixed evenly. Due to the wide variety of spinning raw materials, the fiber properties and impurities contained are different, so the opening process of the raw materials is also different. It is involved in cotton spinning, wool spinning, silk spinning and other processing. How to judge its quality? I have summarized the following points for everyone: The quality of the opener is especially reflected in the quality indicators and falling objects of the semi-finished products (fiber rolls or fiber layers) after opening. 1. The type and number of impurities and defects in the semi-finished products 2. The structure and uniformity of the semi-finished products; 3. The content of short fibers in the semi-finished products 4. The opening degree of the fiber block is expressed as the average weight of the fiber block (g/block), the unit volume weight (kg/m3) or the free sedimentation rate of the fiber block in the air. 5. The number of spun fibers contained in the droplets. In order to further improve the opening quality of textile raw materials and yarn quality, the main development direction of the opening process is to improve the shape and structure of the opening mechanism, and widely use white wine rollers, needle looms and other carding machines. Or needle drums can improve the opening degree of fiber blocks, improve the structure and uniformity of semi-finished products, and enhance the pre-opening of fiber raw materials during the opening process. Use and try more free blowing. Reduce the use of airflow and other openings to use loose and impurity removal methods to prevent fiber damage and impurity fragmentation, so as to reduce the resulting yarn defects. The above is the method to judge the quality of the opening machine. I hope it can be helpful to everyone.
