Practice for Enhancing the Antistatic Attenuation Performance of Melt-blown Fabric
In order to improve the antistatic attenuation performance and enhance the filtration efficiency of melt-blown fabric,the process flow and principles of melt-blown have been intro-duced,and the impact of process parameters such as hot air volume,hot air temperature,receiv-ing distance,suction airflow at the mesh bottom,and outside ambient temperature on the per-formance of melt-blown fabric has been introduced in detailed.Using melt-blown fabric MFR1500 PP particles as the main material,multiple sets of experiments are conducted with the addition of a single electret masterbatch and a combination of two electret masterbatches to analyze its filtration efficiency,differential pressure,and antistatic attenuation performance.The results show that the antistatic attenuation performance of melt-blown fabric is not significant-ly improved by changing the proportion of single auxiliary material.Adding 1.0％JC0637+2.0％TK001 electret masterbatch,melt-blown fabric has the best antistatic attenuation performance.
