3D-MASK For COVIO-19
Primula Modesta has developed and started selling a reusable cloth mask that protects against viruses of 0.1 to 0.3μ using a non-woven fabric with a high-density sterilization function that was originally developed.（CATALOGUE）
Development background:：
The COVID-19 virus, which is causing a pandemic worldwide, is transmitted by droplets (3.0 to 5.0 μ). Large droplets fall and do not inhale, but small droplets float in the air and are inhaled with the exhalation of a person. If you are using a mask, it will adhere to the surface of the mask and protect it, but as the water in the droplets is lost, it will become the conventional size and will enter the body through the non-woven fabric or fabric of the mask. Therefore, in the medical field, the mask is replaced every 15 minutes when the droplets do not dry to prevent invasion. In the general society, which is not a medical field, the actual situation is that at most several sheets are exchanged a day, and the same mask is frequently put on and taken off. Therefore, there is an increased risk of intrusion, such as
● touching the surface
● droplets drying inside the mask.
The mask developed by Primula Modesta has the following features.
- It is a three-layer structure with a special filter sandwiched between unidirectional water permeable materials.
- The unidirectional water permeable material has the property of actively releasing water from the mouth to the outside, and suppresses invasion into the inside.
- A special filter adsorbs a virus by being charged with static electricity, and the caught virus is sterilized with silver ions to prevent infection.
- Moisture contained in exhaled breath is actively released to the outside so that the mouth does not get stuffy.
- With a thickness of2.5 mm, it does not cause suffocation without being blocked by other foreign substances that make up most of the air.
- The sterilization and deodorant functions do not cause odor even after long-term use.
- You can wash it in the washing machine about 60 to 100 times and use it repeatedly.
- The ear straps are made of knitted fabric and are soft and do not hurt.
