Masks have a certain filtering effect on the air entering the lungs. To achieve a good filtering effect, the key is the core filter layer! Melt blown cloth is the most important filter material that must be used in disposable protective masks. There are a wide variety of masks on the market, and there are also various grades of meltblown. Consumers can easily buy poor quality meltblown without paying attention. What kind of terms should be purchased? Today, let’s discuss the procurement of disposable flat masks. Novice buyers can take a look. Regarding the procurement of mask materials, have you chosen the right one?

1. Material classification of flat masks

In the medical industry, one of the main purposes of flat masks is to solve the problem of droplet-borne diseases. Masks are generally made of three layers of non woven fabric. The material is spunbond nonwoven fabric + meltblown nonwoven fabric + spunbonded nonwoven fabric. You can also switch to short fiber non woven fabric to improve the skin touch, that is, ES hot-rolled non woven fabric + melt-blown non woven fabric + spunbonded non woven fabric. The outer layer of the mask has an anti-droplet design, the middle layer is filtered, and the memory absorbs moisture.

2. Flat mask specifications

Masks are divided into 2-layer non woven masks, 3-layer non woven masks, and 4-layer activated carbon masks. The size specification is 17.5×9.5cm (adult), 15×9cm (child).

3. Flat mask raw materials

1) 2-layer mask: non woven fabric, nose strip, ear hook.

2) 3-layer mask: non woven fabric, nose bridge, ear hook, meltblown filter cloth.

3) Activated carbon mask: non woven fabric, nose strip, ear hook, melt blown filter cloth, activated carbon cloth.

4. Plane mask material purchase

First: The grade and grams of meltblown non woven fabrics are important to confirm. The main material of meltblown is polypropylene, which is a kind of ultrafine electrostatic fiber cloth, which can capture dust. After the dust is captured by the ultra-fine electrostatic fibers, it is extremely difficult to detach due to washing, and washing with water will also destroy the electrostatic dust collection ability. The meltblown filtration levels suitable for flat masks are: ordinary, BFE95 (filtration efficiency 95%), BFE99 (filtration efficiency 99%), PFE95 (filtration efficiency 99%), KN90 (filtration efficiency 90%). The weight range of meltblown cloth is 20-25g. If you are not sure about the weight and you have samples in hand, you can send samples to the manufacturer for confirmation.

Second: Activated Carbon Booker is an important confirmation. If you need to make an activated carbon flat mask, you need to confirm the weight of the activated carbon cloth. Activated carbon cloth is made of high-quality powdered activated carbon as the adsorption material, and is made of polymer adhesive material attached to the non woven fabric matrix. It has good adsorption performance, thin thickness, good air permeability, and easy thermal synthesis. It can effectively adsorb various industrial waste gas, such as benzene, formaldehyde, ammonia, chlorine dioxide, etc. Mainly used to make non-woven activated carbon masks. Commonly used weights are 32g, 35g, 40g, 45g.

Third: PP spunbond fabric. Determine the color, weight and width of the spunbond fabric. All the colors in the non woven Pantone color card can be made, but each manufacturer has its own color card. If the quantity is large, you must first communicate the color with the manufacturer. by weight and width.
