Melt Blown fabric is a non-woven fabric made by extruding molten polymer through a die with many small holes. As the polymer exits the die, high-velocity air jets impact the thin streams, causing them to elongate and cool rapidly into very fine fibers. These fibers are then collected on a moving screen or conveyor belt to form a thin web. The resulting fabric has extremely fine fibers that form a dense mat with small pores, giving it excellent barrier properties against particles, liquids and bacteria.

Features of Melt Blown Fabric

Microfiber Marvel
The standout feature of melt blown fabric lies in its microfiber diameter. The microfibers created through the meltblowing process are incredibly fine, contributing to the fabric's exceptional filtration efficiency. This intricate microstructure enables the fabric to capture even the smallest particles, including bacteria and viruses, making it indispensable in environments demanding high levels of filtration.

Filtration Excellence
Melt blown fabric's fine fiber structure translates directly into its high filtration effciency. The densely woven matrix of microfibers effectively traps particles, contaminants, and pollutants, rendering it indispensable across various sectors, from healthcare to manufacturing.

Versatility Embodied
The versatility of melt blown fabric is evident in its extensive array of applications. It serves as a linchpin in the production of surgical masks, N95 respirators, and other personal protective equipment (PPE), where its filtration prowess is of paramount importance. Furthermore, it finds utility in air and liquid filtration systems, oil sorbents, and even within the automotive industry for cabin air filters.

Adaptability
Melt blown fabric can be engineered to meet specific performance requirements by adjusting the melt flow rate, fiber diameter, and web density during manufacturing.

Types of Melt Blown Fabric

Standard Melt-Blown Fabric

This type of fabric is used in a wide range of applications, including air and liquid filtration, medical masks and gowns, and industrial wipes. It has a high degree of filtration efficiency, typically in the range of 70-95% for particles of 0.3 microns in size.

Oil-Absorbent Melt-Blown Fabric

This type of fabric is designed to absorb oil and other hydrocarbons, making it useful for cleaning up oil spills and other environmental disasters.

Electret Melt-Blown Fabric

This type of fabric is treated with an electrostatic charge to enhance its filtration efficiency. It is commonly used in air filtration systems, such as in HVAC systems, to capture small particles and pollutants.

Composite Melt-Blown Fabric

This type of fabric is made by combining two or more layers of melt-blown fabric with other materials, such as spunbond nonwoven fabric or other types of fibers, to enhance its strength and durability. It is commonly used in the production of medical and surgical gowns, drapes, and other protective clothing.

Nanofiber Melt-Blown Fabric

This type of fabric is made using nanofibers, which are ultrafine fibers with diameters in the range of 100 nanometers or less. Nanofiber melt-blown fabric has a higher filtration efficiency than standard melt-blown fabric, making it suitable for use in high-performance air and liquid filtration systems.

Advantage Of Using Melt Blown Fabric

Low Pressure Drop

Melt-blown nonwoven fabric has a low pressure drop, meaning that air or liquid can pass through the material with minimal resistance. This is important in filtration applications where a high flow rate is required.

Lightweight

Melt-blown nonwoven fabric is lightweight, which makes it easy to handle and transport. This is especially important in applications where weight is a critical factor, such as in the production of medical masks and gowns.

Soft And Flexible

Melt-blown nonwoven fabric is soft and flexible, which makes it comfortable to wear and use. This is important in applications where the fabric comes into contact with the skin, such as in medical masks and gowns.

Chemical Resistance

Melt-blown nonwoven fabric is resistant to a wide range of chemicals, making it suitable for use in harsh environments.

Process of Melt Blown Fabric

Polymer Preparation
The first step is to prepare the polymer raw material, usually a thermoplastic resin such as polypropylene (PP), most commonly by melt-blowing. The resin is dried to remove moisture that may otherwise reduce the quality of the final product.

Melt Extrusion
The dry polymer is fed into an extruder where it is heated to a molten state. An extruder forces molten polymer through a spinneret containing a large number of small holes.

Fiber Formation
As molten polymer is ejected from the spinneret, a high-velocity jet of hot air strikes the liquid polymer stream. This causes the polymer to stretch and solidify into thin fibers. The diameter of these fibers is usually measured in microns and can be controlled during the process to meet specific requirements.

Bonding
In order to improve the structural integrity of the fiber web, it can be subjected to a bonding process. This may involve calendering (passing the web through rollers), thermal bonding (applying heat to fuse the fibers together), or using adhesives.

Finishing
After the fiber web is formed and bonded, it may undergo additional finishing steps. This can include cutting the fiber web into narrow rolls, treating it with an antistatic agent, or applying a waterproof coating.

How to Choose Melt Blown Fabric

Melt Flow Index

First consider the melt flow index. The improvement of polypropylene MFI can reduce the working temperature of the screwextruder, increase the melt flow rate, help reduce the formation of excessively degraded polymers, extend the life of the melt blown die head, and reduce energy consumption. Generally, melt-blown material with a melt index of 1500 ± 100g / min is selected, and the melt viscosity is lower, which is more suitable for the weak drafting effect of the melt-blown processThe molecular weight distribution.

Ash Content Of Melt-Blown Material

The ash content needs to be determined with the manufacturer. The diameter of the spinneret hole of the die used in the melt-blowing process is small. If the ash content of the melt-blown material is too large and the impurities are too large, the spinneret hole is easily blocked. Choosing a low-ash melt-blown material can effectively extend the melt-blown die head replacement cycle, reduce energy consumption, and reduce product production costs.

Disadvantage Of Using Melt Blown Fabric

Higher Cost
Melt-blown nonwoven fabric is more expensive to produce compared to other types of nonwoven fabrics and traditional woven fabrics. This is because it requires specialized equipment and materials to produce the fine fibers.

Limited Durability
Melt-blown nonwoven fabric may have limited durability compared to other types of fabrics, especially in applications where it is exposed to harsh environments or mechanical stress. However, the durability of the fabric can be improved by combining it with other materials, such as spunbond nonwoven fabric.

Limited Availability

Melt-blown nonwoven fabric may be in short supply during times of high demand, such as during a pandemic when there is increased demand for medical masks and other protective equipment.

Flammable

Melt-blown nonwoven fabric can be flammable, which may be a concern in some applications. However, flame retardant additives can be added to the fabric to improve its fire resistance.

Environmental Concerns

The production of melt-blown nonwoven fabric can generate significant waste and emissions, which can have negative environmental impacts. However, efforts are being made to develop more sustainable production methods and to recycle or repurpose used fabric.

How to Maintain Melt Blown Fabric
