Non-woven breaks through the traditional craft of textile, it is not yarn knitting together, it is combining the fibers directly through physical methods. There isn’t chemical binder in production,the fiber web is even distribution, so no fibers come off during usage, it is excellent longitudinal and transverse tension. Do you know what non woven fabric is used in masks?
According to different production process , there are many different non-woven series, meltblown nonwoven fabric and spunbond nonwoven fabric is the main materials in masks production.
Meltblown nonwoven fabric is the main filter materials of different type mask, it is in the middle layer of mask.there are white and black，the feature is non-toxic, harmless to human physiology, excellent breathability, good filter efficiency for bacteria and virus.There are different filtration standard as follows:
Surgical Mask Filter
| Model | Weight(g/㎡) | Particle filtration rate @0.1µm(%) | Applications | Standard |
| BFE95 | 20~25 | 95 | Electronics, industry and surgical medical in hospital | EN14683:2005 |
| BFE99 | 20~25 | 99 | ||
| VFE99 | 20~25 | 99 |
Anti-dust Masks filter
| Model | Weight(g/㎡) | filtration rate @0.3µm(%) | Aerosol | Standard |
| N95 | 40~50 | 95 | Nacl | USA standard |
| N99 | 40~50 | 99 | ||
| FFP1 | 30~40 | 80 | Paraffin oil Particle | Europe Standard |
| FFP2 | 30~40 | 94 | ||
| FFP3 | 40~50 | 99 |
Spunbond nonwoven fabric also is the main material of face mask, usually it is in the top and bottom layer of masks. Any colors can be make, and can printing on it.The feature is high temperature resistance,anti-aging, uvioresistant, high elongation, good stability and breathability,non-toxic and hydrophobic.
Some raw materials of the most common types of non-woven fabrics used in face masks include:
- Polypropylene. Polypropylene is a synthetic fiber that is often used in non-woven fabrics. It is a strong, durable, and water-resistant material that is also relatively inexpensive. Spun bonded polypropylene fabric is great for face masks because it provides good filtration and is comfortable to wear.
- Polyester. Polyester is another synthetic fiber that is often used in non-woven fabrics. It is a strong, durable, and wrinkle-resistant material that is also relatively inexpensive. PET spunbond nonwoven fabric is a good choice for face masks because it provides good filtration and is easy to care for.
- Nylon. Nylon is a synthetic fiber that is often used in non-woven fabrics. nylon non woven fabric is a strong, durable, and water-resistant material that is also relatively expensive. Nylon is a good choice for face masks because it provides good filtration and is comfortable to wear.
- Cellulose. Cellulose is a natural fiber that is often used in non-woven fabrics. It is a soft, absorbent, and biodegradable material that is also relatively inexpensive. Cellulose is a good choice for face masks because it is comfortable to wear and is environmentally friendly.
