Spunbonding is a manufacturing process used to create nonwoven fabrics. It involves melting plastic pellets, which are then extruded through a spinneret to form continuous filaments. These filaments are laid down on a conveyor belt and bonded together using heat or pressure, resulting in a strong, lightweight material. This technique is commonly used in various applications, including medical supplies, geotextiles, and packaging. The resulting fabric is durable, breathable, and can be produced in large quantities, making it a popular choice for many industries.
