Spinnvlies

Spinnvlies, also known as spunbond nonwoven, is a type of nonwoven fabric made from continuous filament extrusion. In this process, thermoplastic polymers like polypropylene or polyester are melted and then extruded through a spinneret. The molten polymer strands are then cooled and laid down in a random pattern onto a moving conveyor belt. This web of filaments is then bonded together using heat or chemical treatments to form a cohesive fabric. The resulting material is lightweight, strong, and has good breathability. Spinnvlies is characterized by its web-like structure, where individual fibers are not woven or knitted but are instead bonded together. The properties of spinnvlies can be modified by adjusting the type of polymer used, the filament denier, and the bonding process. Common applications for spinnvlies include disposable hygiene products like diapers and sanitary napkins, medical textiles such as surgical gowns and masks, agricultural coverings, and geotextiles. Its versatility and cost-effectiveness make it a widely used material across various industries.
