Spunbond term is typically used to recognize fabrics, such as felt (geotextile or thermally/chemically bound), which can be neither knitted nor woven. Spunbond is produced by depositing extruded continuous filaments onto a collecting belt in a uniform random manner followed by bonding different types of fibers. Specific polymers (usually Polyester and Polypropylene) granules or flakes (bottles recycled Polyester) are melted and pressed through spinnerets to form filaments. Formed filaments are stretched by compressed air and lead down to a belt by vacuum, randomly forming a web. After web forming step, it’s mechanically bound by one or more needling looms or by calender (point, embossing or flat).
Spunbond is used in the textile industry and it’s the most popular nonwoven all over the world.
