Polyester Color Yarns Suppliers

 The rotation speed of the cotton swab should also be controlled. This requires real-time replacement of the tension gear. The friction coefficient of the false twister will affect the hairiness of the finished yarn. The roving weight unevenness is mainly controlled 1.As the last process of the pre-spinning, roving is not only an important factor that affects the spun yarn, but also the sliver, spectrum, and hairiness. The sliver cans should be placed regularly to avoid them.

The routine maintenance of mechanical parts and bobbins should be strengthened. 2. Large deviations will also cause serious quality problems such as uneven spun yarn weight and strong CV.. For example, the sliver cans for internal yarn placement are placed close to the machine, and the sliver cans for external yarn placement are placed far away from the machine. Rolling waves are sometimes found in pop charts. It is necessary to reasonably select the false twister for the front and back rows of the roving to reduce the difference in tension between the front and back rows of roving. 5.

The daily inspection and maintenance of carding and drawing equipment and the quality control of the laboratory.Due to the difference in the diameter of the bobbin and the wear of the bobbin hole diameter or bottom, the poor fit of the spindle groove and the pin of the spindle, the improper pressing of the palm or the position of the palm, and the number of palm pressing circles,

the number of spindles Varying heights or uneven spindle operation caused by other reasons will cause differences between the spindles of the same row of roving elongation laws, affecting the roving draw. In addition, the tension of the roving also changes with the Polyester Color Yarns Suppliers temperature and humidity of the workshop. 4, the placement of sliver cans. Causes uneven weight distribution inside and outside. 6. 3
