Extrusion System:The process begins with the extrusion of polypropylene granule fiber, chosen for its desirable properties.The extruder melts the granules to form a polymer melt, which is then spun into filaments.
Spinning Assembly:The spinning assembly pulls the molten polymer through spinnerets, creating continuous filaments.These filaments are then laid down in a random or controlled manner, forming the basis of the nonwoven fabric.
Meltblown Technology:In addition to spunbond technology, some machines incorporate meltblown technology in the same production line.Meltblown involves further processing the filaments into ultra-fine fibers, enhancing the fabric's filtration and barrier properties.
Web Formation:A web former machine arranges the spun filaments into a web-like structure.This web is then consolidated to create the nonwoven fabric.
Lap Winder Machine:The lap winder machine collects and winds the produced fabric into rolls or sheets for further processing or distribution.
Working Process:
Material Preparation:Polypropylene granules, specifically designed for the process, are loaded into the extrusion system.
Extrusion and Spinning:The extruder melts the polypropylene, and the spinning assembly converts it into continuous filaments.
Formation of Web:The filaments are laid down onto a moving belt or drum to form a web.
Consolidation:The web is consolidated through heat and pressure, bonding the filaments to create a cohesive fabric.
Optional Meltblown Process:If the machine includes meltblown technology, additional processing refines the fabric's structure.
Winding and Collection:The lap winder machine collects the finished fabric, winding it into rolls or sheets.
Can it produce both spunbond and melt-blown fabrics simultaneously?
Simultaneous Production of Spunbond and Melt-Blown Fabrics:
The capability of producing both spunbond and melt-blown fabrics in a single machine is a distinctive feature of advanced
Nonwoven Spunmelt Machines. These machines integrate two key technologies—spunbond and meltblown—within the same production line.
Spunbond Technology:Spunbond technology involves extruding polymer granules, typically polypropylene, into continuous filaments.The filaments are then laid down randomly or in a controlled manner to form a web.
Melt-Blown Technology:Melt-blown technology takes the process further by subjecting the filaments to additional processing steps.
The filaments are attenuated through high-velocity air, creating ultra-fine fibers and enhancing the fabric's filtration and barrier properties.
Key Advantages of Simultaneous Production:
Cost Efficiency:Simultaneous production of both fabric types in one machine reduces the need for separate production lines, leading to cost savings.
Streamlined Workflow:The integration of spunbond and melt-blown technologies streamlines the manufacturing process, making it more efficient and reducing production time.
Versatility in Applications:The resulting fabric can be tailored to meet specific requirements, making it suitable for a wide range of applications.
Applications include face masks, medical garments, hygiene products, and other uses where a combination of spunbond and melt-blown characteristics is desired.
Enhanced Product Performance:The combination of spunbond and melt-blown features in a single fabric can enhance its overall performance, providing improved strength, filtration capabilities, and barrier properties.
