Melt spray electret material -- ZJ-01 and melt spray PP raw material are mixed evenly in accordance with the ratio of 1.0 to 4.0wt% and then directly processed by melt spray spinning.The proportion of 4.0wt% is added online. Due to the different fineness and accumulation density of the melt spraying cloth fiber produced by each melt spraying line and the different discharge efficiency of electret equipment, the customer can increase or decrease the dosage of ZJ-01 according to the specific situation to achieve the best application effec
