Since novel Coronavirus is spreading, face masks have become an indispensable protective device for people. Suddenly, face masks have become a rare commodity on the market.And the production of masks of raw materials meltblown nonwoven fabrics, due to the gap is too large, in the network has become a hot, but also a difficult point.
Before the epidemic, very few people knew it. After the epidemic, they knew it was a special material for the production of masks.
What is the technology of meltblown nonwoven?
The following follows meltblown nonwoven fabric manufacturer to understand:
Melting spray method: ultrafine polypropylene fiber filter cloth, because it is in the textile industry, is a non-woven cloth, the process is melting spray method, the general name: melting spray non-woven cloth.
There are many varieties of meltblown nonwoven fabrics with wide applications. The truly melt-spray non-woven fabrics used in mask production are the ultrafine polypropylene fiber filter fabrics mentioned above, which meet the quality requirements of masks.
So what are the requirements for the meltblown nonwoven cloth used as a mask?
1. Material: conform to the hygienic standard;
2. Air permeability (transmittance efficiency) : over 95%;
3. Resistance: below 40Pa;
4. Good material hydrophobicity.
Therefore, the technical specifications of ultrafine polypropylene fiber filter cloth meet the production requirements of masks.If the mask is made of melt-sprayed non-woven cloth alone, it cannot meet the quality requirements.
Why should the mask be made with "melt spray ultrafine polypropylene fiber filter cloth"?
Because, go up from material qualitative, the basic index characteristic of polypropylene fiber, characteristic it accords with wholesome standard, avirulent, tasteless, abhorrent water performance is good wait for a characteristic.
From the production process, melting spray method is adopted, because the flow of melting spray technology: mainly through: melting - jet - draft to reach the degree of ultrafine fiber, and the woven cloth is formed by its own heat, so good air permeability and high filtration efficiency.Other production processes are difficult to achieve.
