Operation aspect: The car-stopper must be on duty, to handle the winding parts of the top roller and roller in time, and torn off the roving on the adjacent spindle position of the top roller. Efforts to reduce the weight unevenness and dry CV% value of cotton rolls, raw slivers, semi-cooked slivers, and cooked slivers; 2. The whole large-scale seersucker (cotton mouse) has appeared recently and is irregular.Longjin lifting part: There is no setback during lifting and commutation.5%; 7. The difference in the elongation of large and small yarns should be Black Polyester Yarn Suppliers controlled within 1. Strengthen process temperature and humidity control. It is easy to produce curved fiber bundles, which leads to the increase of slub yarn defects, especially for combed bars with good fiber straightness and parallelism. There are many factors that affect the evenness of the roving sliver.) 5. is unreasonable, resulting in poor drafting; 5. Achieve appropriate standards, adjustment methods (air conditioning facilities), diligent adjustments and eliminate regional differences in temperature and humidity. Comb, merging, thick beard strip, sliver channel is not smooth, It causes sticking, hanging, winding, accumulating, and belting; 6. Our company has two FA457 rovings, which are spun up to about 600 meters. When higher speeds are used, the maintenance of rubber rollers should be strengthened to ensure that the air suction is normal, and the relevant processes should be reasonably configured to reduce yarn defects. Give full play to cotton cleaning, carding,The function of the self-leveling device on the draw frame; 4. 9. Reasonable process design and accurate machine operation, the process difference between the eyes, the spindles and the tables should be eliminated. Therefore, when producing high-grade combed yarns, the final parallel delivery speed should be controlled at 300~350m/min.
