The suction nozzle and the vacuum suction points in the triangle area

16mm) FLUFFY Polyester Yarn can be seen from Table 8 that the speed of the spur roll is low and the efficiency of removing impurities in a single machine is low, but the speed of the spur roll is high, and the growth rate of short pile and the sliver neps content also increase. 3.8 The effect of the negative bottom of the dust removal system on the production of neps and short velvet content

Now there are many negative pressure suction points on the carding machine, such as the rear car belly dust removal system, the negative pressure suction nozzle of the carding part, and the cover cotton net cleaning system. The suction nozzle and the vacuum suction points in the triangle area, especially the vacuum suction of the rear belly part and the cover part, the most obvious effect is the discharge of short pile and clutter. 4

Conclusion Modern cotton spinning equipment is high-speed, high-yield and highly automated. It uses HVI, AfiS and other high-tech testing instruments to eliminate impurities in raw cotton to the greatest extent on the production line of the carding process while minimizing neps and linters. It plays a very important role in reducing the burden of post-process and improving product quality. References: [1] Qin Zhenjun, New Technology of Modern Cotton Spinning,
