Meltblown fabric is an efficient filtering material that melts polypropylene and other materials at high temperatures, forms fine fibers through spinning, and then forms a filtering layer through natural stacking or electrostatic adsorption. The fiber gap of the meltblown cloth mask is small, the filtration efficiency is high, and it can effectively block small particles and droplets. In addition, meltblown fabrics can also undergo electrostatic treatment to increase filtration efficiency.
The safety of non-woven meltblown fabric masks
The non-woven meltblown fabric mask combines the advantages of non-woven fabric and meltblown fabric, ensuring comfort while providing efficient filtration performance. When selected and used correctly, this type of mask is safe. They can effectively block viruses, bacteria, and other harmful substances in the air, protecting users’ respiratory health.
However, it should be noted that the protective effect of masks also depends on the way they are worn and the environment in which they are used. Users should ensure that the mask fits tightly against their face to avoid air leakage; At the same time, in high-risk environments such as hospitals and areas with severe epidemics, masks with higher levels of protection should be chosen.
Commonly used raw materials for mask meltblown fabric
Mask meltblown fabric is generally made by meltblown technology, which can heat and melt polypropylene plastic or other suitable thermoplastic plastics, shape them through a spinneret, and then use cooling, curing, embossing and other processing techniques to produce the required meltblown fabric material. Therefore, the commonly used raw materials for mask meltblown fabric mainly include polypropylene plastic, PET, etc.
Among them, polypropylene plastic is one of the most common raw materials for mask meltblown fabric, which has the characteristics of light, thin, good breathability, and high filtration effect. Therefore, it is widely used in industries such as masks and protective clothing. In addition, other suitable thermoplastic materials can also be used as raw materials for mask meltblown fabrics, and the specific selection should be based on different needs.
2、 Other mask meltblown materials and processes
In addition to the commonly used raw material polypropylene plastic for mask meltblown fabric, mask meltblown materials also include support layers, filter layers, and protective layers. Specifically, the support layer is generally made of high-temperature resistant and corrosion-resistant synthetic fibers such as polyester fibers and nylon, while the filter layer is made of fibers such as polypropylene and PBT. The protective layer is mainly treated using processes such as electrostatic melting spray and microporous membrane.
In addition, in the application of mask meltblown technology, it is necessary to consider issues such as the selection and parameter tuning of the nozzle. For example, parameters such as the aperture, spacing, and spinning speed of the spinneret can all affect the final quality of the meltblown fabric. Therefore, in practical applications, adjustments need to be made according to different needs.
3、 Summary
The commonly used raw material for mask meltblown fabric, polypropylene plastic, has high breathability and filtration effect, and is therefore widely used in industries such as masks and protective clothing. In addition to polypropylene plastic, other suitable thermoplastic materials can also be used as raw materials, and materials and processes such as support layers, filter layers, and protective layers need to be used for application.
