Melt-blown non-woven fabric is the core filter material of the mask, which is mainly determined by the filtering mechanism of the melt-blown filter material, which is mainly divided into mechanical barrier and electrostatic adsorption.

1. Mechanical barrier

Mechanical barrier has the following situations:

a. Foam can be blocked by filter material.

b. When the diameter of the fine dust is less than 3um, the fine dust is mechanically intercepted by the fiber layer of the curved pores in the filter material of the mask.

c. When the particle size and airflow velocity are large, the particles are captured due to inertial collision with the fibers, and when the particle size is small and the flow rate is low, the particles are captured due to Brownian motion hitting the fibers.

2. Electrostatic adsorption

Usually electret treatment is performed in the production process of meltblown cloth, so that the non-woven fabric has more static electricity and has electrostatic adsorption. Electrostatic adsorption refers to the capture of dust bacteria and viruses by the Coulomb force of the charged fibers when the fibers of the filter material are charged.

There are two ways to improve the charge storage capacity of electret materials:

a. By improving the crystallinity and mechanical deformation of the material, the structure of the material is changed to form fine particles. Long hole channels prevent charge drift.

b. Charge traps are created by introducing additives with charge storage properties to capture charges.

3. Electret treatment

As can be seen from the figure, the key to improving the filtration efficiency of masks lies in the electrostatic storage of melt-blown non-woven fabrics. Under the mask circulation speed, the attenuation of static electricity is not a concern (for example, after leaving the factory, it will arrive at the user in half a month), and normal medical masks are valid for 6 months, while some masks in Japan are valid for three years.

The meltblown non-woven electret is very sensitive to ambient humidity. Sino's customer has done an experiment, stored for 7 days under normal temperature and high humidity (relative humidity greater than 95%), the surface potential of positive and negative corona-charged samples has decayed to 28% and 36% of the initial value respectively. At this time, because the melt-blown non-woven fabric has an open structure, its specific surface area is larger, and it has a larger contact surface with the surrounding environment, making it more sensitive to water vapor, corrosive gases, and charged particles of the opposite sex in the environment. The corona charging system can only generate ionic charges with low beam energy, and most of the charges injected during the charging process are deposited on the near-surface layer of the fabric surface fibers. When the sample is stored or worked in a high-humidity environment, a large amount of charge is lost due to the compensation effect of polar groups in water molecules and anisotropic ions in the atmosphere on the high concentration of surface charges on the fibers. Therefore, in the process of transportation and storage of meltblown cloth, it is necessary to avoid high humidity environment.

Polypropylene pellets are mostly used as raw materials, and are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties.

The non-woven fabric is made of polypropylene spun and directly laid into a net and thermally bonded. The strength of the product is better than that of the general staple fiber product, the strength is non-directional, and the longitudinal and transverse strengths are similar. In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are quite different in chemical structure. The chemical molecular structure of polyethylene has quite strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so that it can be effectively degraded , and enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.

The fibers used in the production of non-woven fabrics are mainly polypropylene and polyester. In addition, there are nylon, viscose, acrylic, ethylene, and vinyl. According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type.

How is Nonwoven Fabric Made?

Have you ever wondered how nonwoven fabric is made? This versatile material is used in a wide range of applications, including clothing, medical products, and household items. Nonwoven fabric offers several advantages over traditional woven fabrics, such as cost-effectiveness, durability, and ease of production. In this article, we will explore the fascinating process of manufacturing nonwoven fabric, looking at the different methods and technologies involved.

Nonwoven Fabric: An Introduction

Nonwoven fabric is a type of textile material that is not woven or knitted. Instead, it is produced by bonding or interlocking fibers together using mechanical, thermal, or chemical processes. The resulting fabric is characterized by its random arrangement of fibers, which gives it unique properties such as breathability, fluid resistance, and strength.

Spunbond Method: Creating Fabric from Continuous Filament

The spunbond method is one of the most common techniques used to produce nonwoven fabric. It involves extruding continuous filament fibers and then laying them down on a moving conveyor belt. This process can be broken down into several steps.

Step 1: Polymer Extrusion

The first step in the spunbond method is the extrusion of polymer granules into a fine thread. The polymer used can be polypropylene (PP), polyester (PET), or other materials depending on the desired characteristics of the final fabric. The polymer is melted and then forced through a spinneret, which is a plate with tiny holes that form the shape of the filaments.

Step 2: Filament Cooling and Solidification

Once the polymer filaments leave the spinneret, they are rapidly cooled and solidified using air or water quenching. This prevents the filaments from sticking together and allows them to maintain their shape.

Step 3: Fiber Laydown

After solidification, the filaments are laid down onto a moving belt in a random arrangement. This is typically done using a technique called 'air-laying,' where high-velocity air streams help distribute and disperse the filaments evenly. The random arrangement of filaments creates the characteristic nonwoven structure.

Step 4: Bonding

To give the nonwoven fabric its desired properties, the filaments need to be bonded together. This can be achieved through various methods, such as thermal bonding, chemical bonding, or mechanical bonding.

- Thermal Bonding: In this process, heat is applied to the nonwoven fabric, causing the filaments to melt and fuse together at their points of contact. This creates a fabric that is strong and resistant to tearing.

- Chemical Bonding: Chemical additives, such as binders or adhesives, are applied to the nonwoven fabric. When activated, these additives form bonds between the filaments, creating a cohesive structure.

- Mechanical Bonding: Mechanical methods, such as needle punching or hydroentangling, are used to physically interlock the filaments together. Needle punching involves pushing barbed needles through the fabric, pulling the filaments and causing them to intertwine. Hydroentangling uses high-pressure water jets to entangle and bond the filaments.

Spunlace Method: The Power of High-Pressure Water Jets

The spunlace method, also known as hydroentangling or water jet entanglement, is another popular technique used to manufacture nonwoven fabric. This method utilizes high-pressure water jets to entangle and interlock fibers, creating a strong and durable fabric with a soft texture.

Step 1: Fiber Preparation

In the spunlace method, fibers are first opened and thoroughly cleaned to remove any impurities or contaminants. This ensures that the resulting fabric meets the desired quality standards.

Step 2: Web Formation

The fibers are then presented as a loose web on a moving belt, forming a nonwoven mat. Various techniques can be used to achieve this, such as carding, airlaying, or wet laying. Carding involves aligning the fibers using a series of rotating drums with wire teeth, while airlaying uses high-velocity air streams to disperse and distribute the fibers. Wet laying, as the name suggests, involves suspending the fibers in water and forming a mat through filtration.

Step 3: Water Jet Entanglement

Once the web is formed, high-pressure water jets are directed onto the mat. The impact of these jets causes the fibers to interlock and form a cohesive fabric. The intensity and pressure of the water jets can be adjusted to achieve different levels of fabric strength and texture.

Step 4: Dewatering and Drying

After the entanglement process, excess water is removed from the fabric through dewatering methods such as vacuum suction or pressing between rollers. The fabric is then dried using hot air or other suitable methods.

Meltblown Method: Microfiber Creation at Its Finest

The meltblown method is a specialized technique used to produce nonwoven fabric with extremely fine fibers. It involves the extrusion of molten polymer through small nozzles and the rapid cooling of the fibers, resulting in a fabric with exceptional filtration properties.

Step 1: Polymer Extrusion

Similar to the spunbond method, the meltblown process begins with the extrusion of a polymer, typically polypropylene, into a fine molten thread. However, in this case, the polymer is forced through much smaller nozzles, creating micro-sized fibers.

Step 2: Fiber Cooling and Collection

As the molten fibers are extruded through the nozzles, they are rapidly cooled using high-velocity air streams. The cool air solidifies the fibers, which are then collected onto a moving conveyor belt or a drum. The random arrangement of microfibers forms a fine nonwoven fabric with excellent filtration capabilities.

Step 3: Electrostatic Charging (optional)

In some cases, the meltblown fabric may undergo an additional step called electrostatic charging. This involves subjecting the fabric to an electric discharge, causing the microfibers to become charged. The electrostatic charge enhances the fabric's filtration efficiency by attracting and retaining particles or microorganisms.

Step 4: Bonding (optional)

Depending on the desired properties of the fabric, the meltblown nonwoven material may undergo a bonding process. Thermal bonding or other suitable techniques can be employed to improve the fabric's strength and durability.

Spunbond vs. Meltblown vs. Spunlace: A Comparison

Now that we have explored the three main methods of producing nonwoven fabric, let us compare their characteristics and applications.

- Spunbond fabric: Spunbond fabric is known for its strength, stability, and versatility. It provides excellent breathability and moisture resistance, making it suitable for applications such as hygiene products, geotextiles, and protective clothing.

- Meltblown fabric: Meltblown fabric is best known for its exceptional filtration properties. The fine microfibers create a dense structure that can capture and retain small particles, making it ideal for medical masks, air filters, and oil absorbents.

- Spunlace fabric: Spunlace fabric stands out for its softness, drape, and luxurious feel. It is commonly used in personal care products, wipes, and medical dressings, where comfort and absorbency are crucial.

In conclusion, nonwoven fabric is a remarkable material that offers numerous advantages in various industries. Through the spunbond, spunlace, and meltblown methods, manufacturers can create fabrics with different properties to suit specific applications. Whether it is for filtration, hygiene, apparel, or household items, nonwoven fabric continues to contribute to our everyday lives with its versatility, durability, and cost-effectiveness.
