Applications of SMS Spunbonded Fabric

The textile industry has seen remarkable technological advancements in recent years, and one of the breakthrough innovations in nonwoven fabric production is the SMS (Spunbond-Meltblown-Spunbond) spunbonded production line. SMS spunbonded fabrics have gained immense popularity for their exceptional properties, versatility, and diverse applications. This article explores the SMS spunbonded production line, its key components, and the broad spectrum of industries that benefit from these advanced materials.

SMS spunbonded fabric is a type of nonwoven material formed by a combination of three distinct layers: two spunbonded outer layers and a meltblown inner layer. The spunbonded layers are produced by extruding and stretching polypropylene or other thermoplastic materials to create fine, continuous filaments. The meltblown layer, on the other hand, is created by melting the same material and blowing it into microfibers, which are then collected to form a web. The combination of these layers results in a fabric with outstanding attributes such as strength, durability, and breathability.

Extrusion System: The process begins with the extrusion of thermoplastic polymers to create the spunbonded layers. This involves melting the polymer and then forcing it through spinnerets to form continuous filaments.

Spinning and Stretching: After extrusion, the filaments are spun and stretched to enhance their strength and alignment. This process is crucial for achieving the desired properties in the spunbonded layers.

Meltblown Unit: The meltblown layer is produced by melting the thermoplastic material and blowing it into microfibers using hot air. These microfibers are then collected on a conveyor belt to form the meltblown layer.

Lamination and Bonding: The spunbonded and meltblown layers are laminated together through a bonding process. This creates the SMS fabric, which can be further processed to meet specific application requirements.

Rolling and Cutting: The finished SMS fabric is rolled onto spindles and can be cut into various widths and lengths depending on the intended use.

Quality Control: Throughout the production line, quality control measures ensure that the fabric meets the required specifications in terms of weight, thickness, strength, and other performance characteristics.
