How to confirm the bacterial filtration efficiency (BFE)meltbolwn materials and nonwoven fabrics mask? December 4,2020.

With the novel coronavirus growing, the mask demand would be more developing because it is significant for us to protect ourselves and away this virus in daily life. GBPI will bring your some topic news about the meltblown cloths and mask.

Melt blown cloth is the core material for masks to filter germs. Medical masks have three layers, and melt blown cloth is the middle layer. It has strong filtering, shielding and heat insulation properties, and can play a role in sterilizing and isolating viruses. Therefore, melt blown cloth inspection plays a vital role in controlling the quality of masks.For Meltblown and Mask manufacturer, University institution, what do I need to do for meltblown cloth and mask testing? What are the exact test items?


Meltblown Tester



Meltblown cloth testing items include: particulate filtration efficiency (PFE), bacterial filtration efficiency (BFE), longitudinal breaking strength, transverse breaking strength, longitudinal breaking elongation, transverse breaking elongation, air resistance, air permeability, unit area deviation , Appearance, width, microbiological indicators, etc. And  the filtration efficiency is a key indicator of mask quality evaluation. Air resistance, the size of the influence that hinders breathing when people wear a mask. Meltblown Tester will meet these testing item: the bacterial filtration efficiency of the mask meltblownmaterials should not be less than 95%, and the particle filtration efficiency of oily particles should not be less than 90%.


Mask Bacterial Filtration Efficency (BFE)DectectorMask Synthetic Blood Penetration Tester


Mask testing items would be according the standards: ASTM F2100-2019 Standard is specification for material performance of medical masks, EN 14683:2019  Standard is EU medical mask-requirements and test methods. How to confirm the bacterial filtration efficiency nonwoven fabrics mask? GBPI Mask Bacterial Filtration Efficency (BFE) Dectector and Mask Synthetic Blood Penetration Testeris hot testing with precise data for medical mask. And how to do test?
