Types of Non-woven Fabrics
1. Meltblown Non-woven Fabric
What is meltblown non-woven fabric?
Meltblown non-woven fabric is a type of non-woven fabric that is produced by melting fibers and then spraying them to form a fiber web, which is then cooled and solidified. The meltblown process involves heating and melting a polymer compound, which is then sprayed through a nozzle. The melted polymer compound forms tiny fibers, which are carried by an air stream and collected on a collector to form a web. Meltblown non-woven fabric has the characteristics of small fiber diameter, uniform fiber distribution, softness, and good breathability, and is widely used in fields such as masks, protective clothing, medical dressings, and sanitary napkins.
2. Needle Punched Non-woven Fabric
What is needle punched non-woven fabric?
Needle punched non-woven fabric is a type of non-woven fabric that is produced by mechanically bonding fiber groups together. In the production process, the fiber group is first formed into a certain thickness on a needle punching machine. The needle board and needle of the needle punching machine continuously penetrate the fiber group, and in the process of penetration, the fiber group is compressed, stretched, and displaced, causing the fibers to interlock with each other and form a dense web structure. Needle punched non-woven fabric has the characteristics of good wear resistance, high hardness, and good water absorption, and is widely used in fields such as filtration materials, automotive interiors, and carpets.
Above, I have introduced the two types of non-woven fabrics, both of which are not produced by weaving machines. These two types are common types of non-woven fabrics. There are also other types such as thermal bonding non-woven fabric and wet-laid non-woven fabric. Different types of non-woven fabrics have different characteristics and application fields. You can choose the appropriate type according to your needs.
