Anti Bacterial coating with Silver Colloidal reusable Face Masks

THE CONCEPT PAPER FOR PREPARING HIGHLY EFFECTIVE REUSABLE FACE MASKS WITH ANTI BACTERIAL COATING.

RIGHTS OF PATENT APPLIED BY PATENT APPLICATION NO:202041027088

The process of manufacturing the face mask are being applied for patenting purpose.

FACE MASKS are being universally recognized as one of the most important personal protection equipment. These masks are been used by individuals to prevent potentially infections, materials from air, through human to human by covering face and nose. The masks generally used to reduce the risk of Pathogen transfer between individuals hence masks are used to cover the mouth the nose to stop mucus membranes of the nose, lungs with filtering materials. They can be used as protection for asymptomatic individuals or as a ways to contain droplets from symptomatic individuals. However, no mask completely eliminates the risk of exposure to blood or body fluids.

ASTM specifies testing with a droplet size of three microns containing staph. AUREUS average size of 0.6 to 0.8 microns. In order to the called as medical/surgical masks a minimum 95% filtration rate is required. Moderate and high protection masks must have bacterial filtration rates greater than 98%. We have found silver nano coating on face masks provide anti-bacterial affects and the masks which are having multiple layers one of the layers is being coated with nano silver to make mask to become anti bacterial. The process to produce anti bacterial and high effective face masks are being developed the process is required to be patented.

SILVER NANO ANTIBACTERIAL FACE MASKS:-

As the world continue to battle with various viruses and the need of face masks have become a very necessary. Silver nano masks have recognized this need and special face masks are being developed which are washable and reusable. These masks are coated with silver ions and silver ions have anti pathogen properties which are wearable for 8 hours in a day and 7 days in a weak. And which is last longer for 100 washes at above 60 degrees.  Nano silver has become one of the most very widely used since longs. The silver nano particles have antimicrobial properties. Silver nano particles works against bacteria only in ion form there must be a loss of electron while becoming positively charged. Silver ions pierce to the surfaces of the cells of bacterial and damage their DNA as well has the protein structure of bacterial and halting there metabolism and reproduction until they destroy. After the cells have become inactive silver ions live but continue to act against microbes and delivering a constant and continuous anti microbial performance with no toxicity or side effects. Natural silvers antibacterial properties have a proven longstanding reputation as a very effective way to resist and kill more than 650 kinds of harmful bacteria.

               The generic disposable face masks can neither block all pathogens nor eliminate them, making discarded masks a route for disease as the pathogens multiply in its fibers. this is where the silver nano masks have fitted in the silver nano anti bacterial masks produced with a process explained here.The process of making silver nano anti bacterial are being a part of the patent needed.

THE PROCESS:-

The face masks have 3 layers made with only cotton without any colors or chemicals. Each layer of face masks cloth is being disinfected with UVC exposure for 15 minutes.

  1. Next stage is dip the first layer of mask in silver nano liquid for 5 minutes and dried.
  2. The second layer of the face masks is dipped in Silver nano solution for 15 minutes and the process repeated for 3 times.
  3. The third layer of the mask are exposed to UVC for 15 minutes
  4. The next stage is stitch all three layers in very sequence manner and stitched with elastic band to wear the face masks.
  5. The sizes of face masks is quite different from commercially available face masks the size of face masks is maintained with cover up to cheeks near to ears with elastic band straps.
