What is the cloth of meltblown?

meltblown is the most important cloth for making standard masks, which is produced from cut filaments. Filament fabrics are highly resistant to abrasion and pressure, and their permanent use is not a problem. The fineness of each of these filaments is 1 to 5 microns. This feature increases the impermeability of meltblown cloth in surgical masks. The meltblown layer in the mask is also known as filter paper. Of course, being paper does not mean a dry, inflexible layer. Rather, it is a soft and flexible layer. meltblown is a kind of non-woven fabric with extremely fine fibers. This fluffy and soft product can absorb oils and microbes. At the same time it does not make breathing difficult. So while filtering the air, it can pass the required oxygen to the airways.

meltblown is used to make three-layer surgical masks and is used by doctors, nurses and other hospital staff. It is also used in contaminated environments such as petrochemicals, laboratories and the steel industry. Another feature of the meltbown  layer is its resistance to chemicals. In addition to filtering microbes, this layer prevents chemical contaminants from entering the airways.

Reasons and how to use meltblown cloth in breathing mask?

This cloth has a new generation of environmentally friendly materials that have the ability to breathe, flexibility, lightness, non-burning, easy decomposition, non-toxic, non-irritating, recyclable and …. The meltblown layer in the masks is very soft and flexible with very fine fibers that, like a filter, prevent the entry of germs, nanometer particles and chemicals while not causing problems for respiration and oxygen passing through it to enter the respiratory tract. he does. This fabric is produced in different weights, the best weight for the mask is 20 to 40 grams. This fabric is produced by meltblown technology and polypropylene fibers.

How to detect meltblown?

You can use the following methods to identify a standard mask with a blue layer layer:

1- Water does not pass through the mask.

One of the best ways to detect the presence of meltblown cloth in a mask is to keep water and other liquids out of the mask. For this purpose, take the mask under the tap. The meltblown layer prevents water from passing through the mask, so if water passes through your mask, it indicates that this layer has not been used in the mask and is a fake mask.

Note that the meltblown layer does not change any state when wet and there is no trace of moisture in it, so if your mask is wet, even if water has not passed through it, be sure that it does not use the meltblown fabric.

۲. Are you able to extinguish the candle when you put on the mask?

To make sure that the meltblown layer is in the mask and that it is standard, apply the mask to your face and try to extinguish the candle flame by dying. If the candle does not go out, a layer of meltblown is used in your mask.

3. Your mask should absorb the fine particles of the tissue

Another way to make sure you buy a three-layer meltblown mask is to chop a piece of tissue paper thoroughly and place it on the table. Then hold the two straps of your mask in your hand and gently bring the mask close to the shards of the paper towel.

4. If you look at the light source with your mask, do you recognize the light source?

In a dark environment, turn on the flashlight of your mobile phone, place the mask at a distance of 10 cm and look at the light from inside the mask. If you saw the light in the form of a halo and the light source was unknown to you, the mask is made of meltblown fabric.

5. Peel off the layers of your mask and hold it against the fire, does it catch fire?

You can cut one of your masks with scissors and separate the layers, then take the middle layer against the flame. The most important feature of meltbown fabric is its fire resistance. This fabric does not catch fire, but in the heat, only its texture is damaged and destroyed, and no trace of burns can be seen on it.

Important points regarding the three-layer mask of the meltbown

The meltblownlayer in masks is vulnerable to alcohol and disinfectants and loses its filtering properties, so avoid disinfecting your mask and spraying alcohol on the mask, as this will damage its texture.

meltblown is not resistant to washing and detergents, so these masks are disposable and will lose their properties if washed. It is recommended to use these masks only for one working day and then throw them away, because if your mask is contaminated, this contamination will be transmitted to you when you use it again.

With the arrival of the corona virus, Vista artatoos Ariya (VATA) medical co launched a meltblown cloth product line for 3-layer masks. meltblown of this company is produced from quality polypropylene materials and has a soft, regular and good density texture and is produced with a weight of 17 to 30 grams per square meter.
