Material -Meltblown
This is main important material for disposable/KN95 mask, standard filtering effect has to achieve ≥95%. Our KN95 is using two layers of meltblown to ensure filtration, other manufacturer may using only one layer. Then, our KN95 include 5 layers, others are mostly 4 layers.
Nonwoven
Market has S and SS levels:
S nonwoven | Mainly used for packing industry, more harder |
SS nonwoven | Mainly used for hygienic industry, more softer |
Our KN95 is using two layers of SS nonwoven, however, some mask manufacturer is
using both in S nonwoven or SS+S in a mask. SS nonwoven cost is around 4% higher than S nonwoven.
