Reliable and Safe: The Melt-blown Filters Part2

- 0 Comments

The HEPA filter of the air purifier or the liquid filter used in the water treatment process are also made of Melt-blown. Not only that but Melt-blown is also used for filter purposes, as well as sanitary materials, clothing, packaging materials, and battery separator.

One of the leading companies that makes Melt-blown is Welcron. Welcron's Melt-blown has excellent ultra-polar yarn size and uniformity. Also, the elastic nonwoven fabric is an excellent filter that is safe to use and is made of a fiber material. And since static electricity was added during the Melt-blown process, the filtration efficiency is still very effective even if it is made with less density, and its lesser density it also gives better breathability, giving the user a refreshing feeling even while wearing the mask. Furthermore, since it is soft, it also causes less skin troubles.

Additives added to Melt-blown include titanium dioxide, UV stabilizers, and nuclear forming materials that can be normally added to non-woven fabric manufacturing.

The test facility, which is used to check the performance of finished nonwoven fabric, is also used by government agencies such as the Ministry of Food and Drug Safety, and has public confidence.

As mentioned earlier, static electricity is added during the Melt-blown process, but because a melt-blown nonwoven fiber is processed with the thin synthetic fibers, it naturally creates more static electricity. So, the filter tends to absorb all fine foreign substances into itself. However, if too much is adsorbed in the process of using the melt blown filter, breathing becomes difficult and bacteria can proliferate, so it is not recommended to reuse repeatedly.

Also, note that most of the MB filters on the market are for masks only, but there may be industrial use among them, so it is essential to check if the filter is for masks when purchasing an MB filter.

I've summarized the melt blown nonwoven fabric/melt blown filter as briefly as possible, and I hope this information is helpful to you. If you have any questions or information you would like to add, please leave them in the comments below or email us.
