As a result, the electrostatic needle filtration fabric has higher purifying efficiency and lower resistance, but the purifying efficiency would decrease a lot after using scour, laundry powder, 84 disinfector and water to wash the fabric respectively.

• 试验结果表明，针刺荷电纤维过滤PM_(10)性能较好(高效、低阻)，但是洗洁精、洗衣粉、84消毒液及清水都会使它的过滤效率降低很大，不宜洗涤。
