Production of nonwovens has a conveyor to carry the spunbond filaments to a perforated drum with inner suction, and external pressure water sprays, to give isotropic nonwovens

摘要

For the production of a nonwoven, spunbond filaments are fed (21) to a conveyor (22) to a perforated drum (24). The interior (26) of the drum is at an underpressure. Water injectors (25) spray water at the material around the drum surface, and is extracted by the inner suction.
