N95 is a 5 layer mask.
N: This is a Respirator Rating Letter Class. It stands for Non-Oil meaning that if no oil-based particulates are present, then you can use the mask in the work environment. Other masks ratings are R (resistant to oil for 8 hours) and P (oil proof).
95: Masks ending in a 95, have a 95 percent efficiency. Masks ending in a 99 have a 99 percent efficiency. Masks ending in 100 are 99.97 percent efficient and that is the same as a HEPA quality filter.
The normal medical mask contains 3 layers of non-woven fabric, spunbond + meltblown + spunbond.
Meltblown fabric is the heart of the mask. It is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs.
Melt blown fabric is a film made of high melt index polypropylene. The fabric is composed of many criss-cross fibers stacked in random directions.
Nitrile Gloves are the perfect compromise between latex and vinyl. Nitrile is made from an allergy safe compound that feels a lot like latex but it's much stronger, costs less, and is more comfortable to wear. Nitrile is perfect for demanding applications, especially in medicals during global pandamic. Powder free gloves go through an extra process of chlorinating the gloves to ease donning.
Nonwoven Advantage:
1. Light: Polypropylene is the main raw material; specific gravity is 0.9, is only third five, fleecy and touches well.
2. Flexibility: made up of microfiber (2-3D), dot by dot thermo-melt formed. Flexibility of products is suitable, comfortable.
3. Water resistance and breathability: slices of Polypropylene and finished products resist water, breathable and easy to maintain and wash.
4. Non-toxic, non-irritating: made of materials which catch up FDA standard, without other chemical composition, stable, non-toxic, no smell, safe for sensitive skin.
5. Anti-bacterial, anti-chemical: Polypropylene is blunt chemical substances can protect in liquid from bacterial and insects; antibacterial, alkali corrosion, erosion and the finished product will not affect sensitive skin.
