In the market, there are many concepts related to fabrics, but when listening to non-woven fabrics, many people wonder. Because you don't know what nonwoven is? have characteristics like? Why is he called with such a strange name? So the shares presented below we will advise carefully. Make sure to help you better understand this fabric.
Nonwoven is a fabric named after its very special manufacturing process. In fact, this fabric is not made through conventional knitting or weaving methods. It is synthesized from Polypropylene particles, also known as synthetic resin.
After these synthetic resin beads are melted, with high temperature they will be spun into yarn. Depending on the intended use, the manufacturer will have other ingredients to match the product. After obtaining the synthetic fiber composition, the membrane will be punched and used by a thermo-mechanical machine or chemical solvents to link them together ... thereby forming a lightweight, porous fabric with the name of non-fabric. weave.
There are many records about the advent of nonwoven fabrics. But according to research, it is because the long continuous movement in the desert makes many travelers difficult. To help keep their feet from getting hurt, they used wool buns to put on the sandals. From the pressure of the feet, the air temperature plus the humidity, the woolen tufts later become light, soft, and spongy material.
In Europe in the 19th century, the garment engineer Garnett is considered the "father" of this fabric. Because he discovered the use of fiber in the manufacturing process. Realizing that a large amount of fiber was wasted when cutting, he researched and built a device that could cut fibers into fibers to make the pillow gut. He then went on to develop a method of tying them together using tape to form nonwoven fabrics.
Non-woven fabric has many outstanding features as follows:
a. High strength and good bearing capacity
This fabric is considered to have good bearing capacity, high elasticity thanks to the properties of synthetic resin. Usually the load capacity of the nonwoven bag will range from 3 to 10kg. Therefore, users are flexible in their purpose and circumstances when using them.
b. Friendly with the natural environment
One reason why non-woven fabrics are chosen by many customers is their biodegradability. After we bury them in the natural environment, decomposition takes place. So it does not pollute or affect the health of the user at all.
c. The price is relatively low
Low cost is also a big factor affecting the purchase of non-woven fabrics by consumers. Thanks to the use of this fabric, it contributes a great part in reducing packaging and production costs. Thereby, consumers will also get an affordable price when buying. Although the price is cheaper, the quality of this fabric is not inferior to other fabrics such as canvas, paper or textiles.
d. The colors are relatively consistent
Because Polypropylene particles are the constituents of the non-woven fabric. Dyeing and weaving are both omitted from the manufacturing process. So manufacturers can adjust the colors to suit user tastes. This is a feature that helps users feel completely secure about the product color to use and preserve the product for a long time.
e. Convenient in printing
With nonwoven fabrics it also allows for extremely efficient use of the surface printing method. Information and images will now be displayed more clearly. So this non-woven fabric is increasingly popular in the retail industry around the world.
Accordingly, manufacturers can print logos and addresses on the surface of the fabric to create an effective smart advertisement.
The manufacturing process of this fabric will go through 4 steps with the starting material being fibers for the paper industry, filament together with fibers of the textile industry. They will then go through the following process:
Step 1: Make a film
The nonwoven film is then made by wet or air method. Film-forming machines will be used with methods such as SB, MB or high-speed drawing.
Step 2: Conduct lining fiber
This is the stage where synthetic fibers will be horizontal layered and stretched on the machine and then mixed and bent to form fibers.
Step 3: Perform the fibrous bonding
In the next step, the fiber films will be linked together through methods such as hydraulic tangling, needle piercing, laminating, using ultrasonic waves, heat bonding ... Each product creation method has different properties. each other depending on the purpose of use.
Step 4: Complete
Finally, the finishing of non-woven fabric is by coating and burning on the fabric surface, then printing and laminated according to users' requirements.
The above article we hope has partly helped you better understand what non-woven products are. Since then, it is understood why this fabric is increasingly popular in our lives.
