In the past, masks were generally manufactured using woven and knitted fabrics as raw materials. However, from the point of view of disposal, after use, most masks today are made of nonwoven film. Nonwoven fabric production is cheaper and more convenient than weaving and knitting. However, information on non-woven fabrics is not really popular. The following article will help you better understand the nonwoven fabrics and their applications to human life.

1. What is nonwoven fabric?

Non-woven fabric (the English name is non-woven fabric) is composed of polypropylene beads, also known as synthetic resin. During the manufacturing process, these materials will be spun into fibers, then linked together by chemical solvents or mechanical heat from modern machines. The end result is fabrics that are thin, light, spongy, and extremely durable.

Why is this fabric called nonwoven? Because it does not have to go through the weaving process like other conventional fabrics.

2. Origin of nonwoven fabric?

Some documents indicate that nonwoven fabrics were accidentally created by travelers traveling through the desert. Because walking on the sand was so hot and painful in their feet, they put on their sandals a wool bun to help ward off the pain.

In the nineteenth century, Great Britain was the leading country in the production of textiles and clothing. In the process, a large amount of fiber is wasted when cutting. It was Garnett textile engineer who discovered this. Since then he invented a special tool to cut excess fibers into fibers and then use them as the intestines of the pillow. Some time later, he again sought to improve them by using glue to stick them together. This is the origin of the most popular non-woven fabric today.

3. Main characteristics of the nonwoven fabric.

3.1. No need to weave.

This is considered a special feature of nonwoven fabrics compared to conventional fabrics. They are formed on the basis of the use of thermal effects from machinery or solvents to bond the fibers together without the need for a weaving process.

The production process of non-woven fabric usually goes through 3 stages including: Creating fiber film, bonding fiber film, finishing treatment. The most commonly used material when making non-woven fabrics is PP or PET (polyster), which are flexible materials, manufacturers apply the technology of spinning directly from plastic particles to form a fiber film, using spunbond or meltblown technique.

+ Spunbond technique: Polymer resin will be melted, extruded through the holes of the spinning head and stretched to the required slenderness and collected into a fiber cushion.

+ Melt blown: In this way, the polymer resin will be melted, extruded through the holes of the spinning head, under the impact of hot air, high pressure and then forming yarn. high-slender fiber. Finally collected into a fibrous membrane.

3.2. Friendly to people and the environment.

The safety and friendliness of the non-woven fabric is reflected in its application in human life. In fact, non-woven fabrics are believed to be used to create products with high safety requirements such as: tea bags, bags, medical masks, tampons, baby diapers, wet towels and some other items.

For items that are in direct contact with human skin, such as masks and wet towels, it is necessary to have extremely high safety and friendliness. Nonwovens have been trusted and used to create these products, demonstrating the superior safety and friendliness of nonwovens.

3.3. Uniform in color.

This is the most prominent advantage that polypropylene possesses. This is considered a special material, does not go through any normal weaving or dyeing processes in the manufacturing process. Therefore, color is the color of great interest. Many people fear that the color of the product is not uniform, but on the contrary, they are very consistent in color, more than other fabrics. To test this, you can bring them out to sunlight for visual inspection.

3.4. Allows printing on the surface.

Like many other fabrics on the market, nonwoven allows us to print on the surface. Images and text are printed depending on the business model and usage needs. However, printing on nonwovens seems more difficult than with conventional fabrics. Companies must have more professional processing skills to ensure appropriate ink coverage, thickness, and color. From there it is possible to create natural images with better standardized color and design.

4. Standard process for nonwoven fabric production.

The nonwoven fabric production process is quite simple, all summarized in about 4 basic layers.

Step 1: Create the film.

This fabric is created by wet or air method, using a melt machine to create film and other methods such as SB, MB, high speed film pulling …

Step 2: Laying the fibrous membrane.

The synthetic fibers will be horizontal, stretched on the machine, then mixed and bent into fiber films.

Step 3: Bonding the fibrous membrane.

Fibrous films will be formed by needle piercing, hydraulic, chemical, ultrasonic, laminating, and thermal bonding. Each method will bring different properties, so depending on the purpose of use, the manufacturer must consider and choose accordingly.

Step 4: Processing is completed.

After coating, burning, printing and laminating as required, the non-woven fabric will be finished.
