Product Overview
Description
What is Nano meltblown？
We supply PVDF nano fiber melt-blown roll, at the size on demand. It's used as core filter media of any high quality mask.
1) The manufacturing process of our nano fiber: Electrospun spinning.
2) The raw material of our nano fiber: PVDF
What are the advantages of nano fibers？
The advantage of our nano fiber melt-blown: Different with those electrostatic element melt-blown fabric which intercept particle
and virus by electrostatic adsorption, our nano fiber has far smaller diameter as 0.3-0.5 micro, with fluffy bushes structure, it
intercept particle physically, so the advantages are:
Higher Efficiency;
Lower Resistance;
Easier breathing.
Durable: Longer Shelf-time, 2-3 years; and，can stand for any loading test.
Washable and Reusability: Eash wash decrease efficiency by 0.3%-0.5%.
What is the difference with PTFE？
PTFE fiber should not be used on face mask, it can be used in industrial filtration
PTFE may has high efficiency, but it has very high resistance, can not breath totally.

Q: Why does nano coated meltblown have high filtration efficiency and low resistance?
A: The wire diameter of electrostatic spinning fiber is 100-300 nm, while the wire diameter of meltblown is usually 3-5 microns.(1micron =1000 nm).The network composed of nano-spinning with very small linear diameter has a smaller pore diameter and can block particles of 0.1 micron, so it has a high filtration efficiency. Meanwhile, because the material structure is vertical and the porosity is high, the air breathing is better.
Q: Is nano fiber coated melt-blown much expensive than general melt-blown?
A: No. After years of research and development, the cost of nanomaterials has been much lower .In FFP2;FFP3 mask production, can replace a layer of melting spray.Masks also have lower resistance and cost less.

Q: can nano fiber coated meltblown smell and affect the comfort of wearing?
A: No.We have a third party test proof, no chemicals, odor residue.And the nano itself is thin, making the mask more comfortable to wear.
Q: Is the dust capacity of nanofiber air purifier products very low?
A: Nanomaterials themselves do have a low dust capacity, and their main function is to filter out finer particles.We match melting spray or electrostatic cotton, effectively solve the dust capacity problem.
Q: What is the lifetime of the nano fiber coated meltblown?
A: 2-3 years and their filtration efficiency can be maintained.
Q: It has been said that it is easier to pass the loading test of the oil test (EN149) using nanomaterials. Why?
Answer: oily loading test, the principle is to simulate the performance of the mask after wearing for a period of time.After the oil loading test, the static electricity will gradually decay, but the physical filtration of nanomaterials can maintain the
filtration efficiency.Therefore, the combination of nanomaterials and melting spray is the best choice.
Q: Is the nano filter element washable?
A: Because nanomaterials themselves are also water-repellent, the filter element can be rinsed to remove large particles of dust on the surface. Generally, an face mask with nano fiber coated meltblown as filter media can be washed 2-3 times maintaining high efficiency.
