Product Overview
Description
What is electrostatic melt blown?
Melt-blown non-woven fabric is a kind of ultra fine fiber non-woven material made by melt-blown process, raw material is foodgrade PP, fibre diameter can be 0.5um-2um. The product is treated with special corona thermal electret electrostatic. It caneffectively filtration and adsorption of microorganisms,viruses and extremely dust.
What is Water Electret Melt Blown?
Water Electret Meltblown is treated the normal melt blown by “water electret process” with “pure water” and “drying process”. This special electret way have characteristics of more higher efficiency and more lower resistance. Our water electret meltblown,pass through a water electret equipment.The friction between
the water and the meltblown cloth generates static electricity.
The advantage of water electret lies in its electrification process, which is carried out in
a high humidity environment. The static electricity on the surface of the meltblown cloth
is washed away by the water,leaving only the static electricity inside the meltblown.
The second process of water electret is a process of drying and electricity locking for
meltblown. The drying process uses the flow of hot air ,the surface temperature is increased
and the surface air flow is increased to dry. This process is actually a working principle of
a static elimination equipment.All the electricity staying outside of the electret masterbatch,
will be taken away. In this second process, a part of the electricity on the surface of the meltblown cloth is eliminated,that is, virtual electricity. Therefore,after the above two processes,the
electret on the polypropylene can be guaranteed to be permanent.

Water electret meltblown features and advantages:
Excellent Water Electret Meltblwon
Compared with the traditional corona thermal electret electrostatic meltblown material,KF94 mask /FFP2 mask meltblown / FFP3 mask meltblown is more saturated with static electricity,and its electrostatic retention is more than three times that of the electric electret,
so the corresponding filtration efficiency is higher.Because the electric field is high,there are few materials to be stacked,thus the amount of polypropylene stacked is only half of the electric electret.The material required is thinner,and the breathing resistance is
correspondingly lower.
Our experiments have verified that the superposition of single layer 40g /50g meltblown
Our experiments have verified that the superposition of single layer 40g /50g meltblown
fabric and double layer 25g meltblown fabric can effectively complete the high filtration efficiency requirements of oil particles of KF94 mask of Korea MFDS standard /FFP2 and
FFP3 masks of EU 《EN149-2001 A1-2009》 standard.At the same time,due to low resistance of water electret meltblownitself,multi-layer superimposed will not result in resistance exceeding standard.
