Domestic enterprises will not face the risk of increased hairiness

The effect of WHITE NIM Polyester Yarn increase on the yarn count and defect of 80 yarns is the same. It can be seen from Figure 8 that when the spindle speed reaches 20500 rpm, the yarn pitch, coarse details and neps are close to the quality control standards. It can be seen that when the speed exceeds 19500 rpm, the quality of the yarn will deteriorate, but the degree is not very obvious. 06 Additional Economic Benefits after Speed ​​Increase Table 1 Output and Energy Consumption of 60 Counts Figure 9 shows that when the speed is increased by 30% (from 16500 rpm to 21500 rpm), 60 cotton yarns in the same unit production time

The output has increased by 27.7% (due to the optimization of the Rieter speed curve, the average yarn drawing speed of a single spindle has been increased), and the energy consumption has increased by 24.8%. Figure 9 Comparison of the output of 60-count and energy consumption Figure 10 Comparison of the output of 80-count and energy consumption, as can be seen from Figure 10, when the spindle speed is increased by 10.8%, the output of 80 cotton yarns increases by 11 during the same unit production time %, the energy consumption per kilogram of yarn production increased by 4.4%.

Therefore, domestic enterprises will not face the risk of increased hairiness, increased head breakage rate and reduced quality as everyone is worried about speeding up spinning machines. On the contrary, according to the test results, throughout the speed-up process, there is no big change in hairiness and decapitation, and the decline in quality is acceptable as long as it is within the set quality control standards.

As long as you grasp the rhythm in the process of speed increase and pay attention to the rate of broken heads, hairiness and quality, you can definitely find a speed suitable for the actual situation of the enterprise. The ultimate purpose of speeding up the spinning frame is to allow enterprises to reduce costs and increase profits.
