Applications of Melt Blown; In Various Industries
The use of Melt Blown in various industries is extensive. This is due to the unique characteristics of this synthetic and industrial fabric.
Melt Blown; Advanced Technology, Affordable Product
Melt Blown (Melt Blown) has a wide range of applications in various industries. This is due to its unique characteristics as a synthetic and industrial fabric. In fact, Melt Blown is a process for producing nonwoven fabrics. It is a product with unique features and is very affordable. Despite this, it has found many uses across various industries.
You may wonder, what exactly are Melt Blown fabrics? Let me give you a simple example. During the coronavirus pandemic, most of you used three or multi-layered face masks. In the production process of these masks, a layer without any specific weave was used. This layer is called Melt Blown. Nonwoven fabrics have important characteristics that make them suitable for use in various industries.

What is Melt Blown and How is it Made?
Before learning about the applications of Melt Blown, let’s first get familiar with the production process of this industrial product. Let’s begin with a simple example. Have you ever seen a cotton candy machine up close? You may have noticed how this machine spins melted sugar into thin, long threads around a stick. The process of Melt Blown production is very similar to this machine. In fact, it is a continuous melt spinning process via air blowing.
The raw material for producing this industrial fabric is polymer. The initial temperature for its production is between 230 to 390 degrees Celsius. Air flow at a speed of over 300 miles per hour hits the polymers, causing the production of discontinuous filaments. These filaments are randomly arranged side by side, in various sizes, forming Melt Blown fibers. Finally, these fibers pass through rollers with high temperatures and are compacted into a defined surface.
A key feature of this process is the ability to adjust fiber density and control thickness. The distance between the dense fibers in the final stage is between 1 and 5 microns. The stages of production include:
- Extruder
- Feed pump
- Melt spinning unit: 1- Distribution of feed 2- Die nozzle 3- Air blowing tube
- Production of fiber mesh
- Winding on cardboard bobbin
- Bonding between fibers
- Final stage

Use of Melt Blown for Making Full Body Isolating Suits
One of the most important applications of Melt Blown is the production of full-body isolating suits. Generally, this product, along with Spunbond, is one of the most important materials used to make high-quality isolating and hygienic suits.
In the past, designing and manufacturing isolating suits was very difficult. This is actually one of the main reasons for the creation of Melt Blown. Traditional medical clothing was not resistant to various contaminants and due to high costs, they were not used as disposable. This caused the transfer of many harmful pollutants from one patient to another.
You may wonder, what exactly are full-body suits? In response, these suits are the ones used by medical staff to protect themselves from various contaminants, covering their entire bodies. These suits are typically used in hospitals and healthcare environments. Their special design and the use of top-quality materials have made the application of Melt Blown in these suits more prominent.
The key features of these suits are heat resistance, good resistance to wear and tear, and the ability to allow air to pass through. As a result, healthcare workers will not face any issues even after long periods of use, and they can feel comfortable while wearing them. This application of Melt Blown can be considered one of the most significant uses of this fabric.

Air Filtration
You might be surprised, but another significant application of Melt Blown is in creating fabrics and materials that can collect various oils. This feature is especially important for individuals working in repair shops and power plants.
As you know, the consumption of industrial oils in such cases is very high. Therefore, it is completely natural to expect that some of the spilled oil on various surfaces needs to be collected. Fortunately, using Melt Blown, materials can be made that allow for quick oil collection. This has become very popular in recent years, and it is considered one of the most important applications of Melt Blown.
Considering all the points above, it can be said that Melt Blown is crucial not only in the medical industry but also in many other important industries worldwide. Moreover, the application of this product in making women’s hygiene wipes cannot be overlooked. These are just some of the most important applications of Melt Blown, and it is expected that its usage in various sectors will continue to increase in the future.
