FIELD: textile, paper.
SUBSTANCE: method of producing spun-bond nonwoven from filaments is described. Elementary filaments are moulded by means of a forming device, then cooled, and then sent with primary air through the extraction device. Primary air exits the extractor with a volumetric flow of VP. Elementary threads follow the exhaust device through the diffuser. Between the exhaust device and the diffuser, a secondary air with a volume flow VS. Elementary strands are laid on the stacker adjoining the diffuser. The volume flow ratio VP primary air to the volume flow VS the secondary air is more than 4.5, preferably more than 5 and very preferably more than 5.5.
EFFECT: device improvement.
