Nano Fibre Cartridge For Filtration Applications

Description and Salient Features of Technology : 

Electro-spun nano-fibre based replaceable cartridge was developed for use in cotton fabric face masks. The aligned electro-spun nano-fibre coated nonwoven fabric is sandwiched with two layers of uncoated nonwoven fabric, which can be inserted within the multi-layer face mask as a replaceable filter media. They are made with biodegradable polymer electro-spun nano-fibres and the produced nano-fibre diameter is around 100 to 300 nm. Due to finer fibre diameter and increased surface area, its effect begins to play an important role in the filter of the most penetrating aerosol particles. Also, they allow more air to pass within the substrate; so it enhances breathability. 

Stakeholders : Face mask manufacturing companies, Common Public

Benefit to Stakeholders : 

• Replaceable attachment for enhanced filtration along with a cotton fabric face mask
• Effective filtration with easy breathing 
• Up to 95 % particle filtration with nanofibre cartridge 
• Consistent performance with high quality

Cost : Cost of the nanofibre cartridge: 5 Rs/ cartridge
