What Makes Na-know Special ?
01
Our Manufacturing Process - Ultrasonic Weld
What Is Ultrasonic Welding?
​
Ultrasonic welding is the binding of materials by applying high-frequency ultrasonic waves and pressure locally to workpieces to create a solid-state weld. A process that requires less energy, man power, and eliminates the need for gluing or stitching.
​
Traditionally the process is used for manufacturing of single-use masks made of 100% polypropylene fibers. Now Na-know has taken the game to a whole new level by utilizing Ultrasonic Weld for the production of reusable cotton masks.

What Is Nanofiber?
​
The term nanofiber applies to fibers with openings of 100 nanometers in diameter or less (100 nanometers is equivalent to 0.1 micrometer.) Nanofiber webs create complex pathways for bacteria, virus and other particles to pass through. The average size of virus attached to water droplets when we cough or sneeze is approximately 1 micrometer; thus, nanofibers with even smaller openings make it difficult for viral particles to be inhaled.
The filtration function of nanofiber membrane is supported by research and data, the material is proven capable to filter 99% of certain viral particles and 100% of bacterial particles. Even after multiple washes, the filtration efficiency is often still greater than 95%.
