Spunbonding is a manufacturing process used to create nonwoven fabrics. It involves melting plastic fibers, usually made from polypropylene, and then extruding them through a spinneret to form continuous filaments. These filaments are laid down on a conveyor belt, where they bond together through heat and pressure, resulting in a strong, durable fabric. This technique is widely used in various applications, including medical supplies, geotextiles, and hygiene products. The resulting nonwoven fabric is lightweight, breathable, and can be produced in large quantities, making it an essential material in industries ranging from healthcare to construction.
