Meltblown Non Woven Fabric and Laminated Non Woven Fabric differ primarily in their manufacturing processes and properties:
1.Manufacturing Process:
(1)Meltblown Non Woven Fabric: Produced by extruding melted thermoplastic polymers through fine nozzles to form microfibers, which are then randomly deposited to create a non woven fabric.
(2)Laminated Non Woven Fabric: Created by bonding together multiple layers of non woven fabric using heat, pressure, or adhesives to form a composite material.
2.Structure and Properties:
(1)Meltblown Non Woven Fabric: Characterized by its fine fiber structure, which results in excellent filtration efficiency and fluid absorption capabilities. It is often used in applications requiring high filtration performance, such as face masks and air filters.
(2)Laminated Non Woven Fabric: Consists of multiple layers of non woven fabric bonded together, which can enhance properties such as strength, durability, and barrier protection. It is commonly used in applications requiring increased strength or water resistance, such as bags, packaging, and medical gowns.
In summary, while both types of non woven fabrics serve different purposes and have distinct properties, meltblown non woven fabric excels in filtration and absorbency, while laminated non woven fabric offers enhanced strength and barrier properties through layer bonding.
