提高过滤效率的方法

a.增大热风流量或温度（增加纤维的细度，减小孔隙率，提高扑捉能力，但阻力增加）；

b.增大静电电压（电流）（极化纤维，增大纤维的静电场能，提高其吸附能力）；

c.在原料中加入粉料或其它驻极体（提高纤维的受电能力和储电时间，让纤维携带更多的电荷和带电荷时间）；

d.加大网底吸风（增大纤维的密实程度，提高纤维的扑捉能力。大克重明显，不常用）；

e.适当降低产量（同工艺下，挤出量变小，纤维变细，阻力增大）；

f.提高模头（模尖）等区的工作温度（熔体流动性变好，纤维变细）；

Polypropylene weather-resistant polypropylene is very sensitive to ultraviolet radiation, adding zinc oxide, dilauryl thiodipropionate, carbon black or similar white filler can improve its aging resistance. Hydrophobic parameter calculation reference value (XlogP) : 3.32, Hydrogen Bond Donor number: 03, hydrogen bond acceptor number: 34, rotatable chemical bond number: 15, Tautomer number: 6, topological molecular Polar surface area: 29.5 avoid strong oxidant, chlorine, store in a cool, dry place with airtight potassium permanganate to ensure good ventilation. MELT BLOWN PP Guangzhou Golden Hair 91500PP 1500g. Increase the spinning ambient temperature (fiber fineness, generally in the case of room temperature rise, resistance increase more obvious, other physical indicators decline) ;. It has a high dielectric coefficient and can be used to make electrical insulating products heated with the increase of temperature. Its breakdown voltage is also very high, suitable for use as electrical accessories. Resistance to voltage, good resistance to arc, but high static electricity, easy to aging in contact with copper.

2、提高产品伸长率的方法

a.适当降低热风流量或温度（结点滑移路径变大，手感变硬）；

b.降低模头（模尖）的工作温度（同上）；

c.适当减小产量；

d.增大熔喷布接收距离（和a或b配合使用效果更明显）；

e.降低环境温度（纺丝环境温度）；

f.增大网底吸风（效果不太明显，大克重较好）；

g.改变纤维角度（改变纤维铺网的结构，不常用）

h.适当提高产量（此方法会造成其它物理指标的降低，不常用）。
