Abstract (en)
[origin: US2016312384A1] A method of making a spun-bond nonwoven fabric of thermoplastic filaments has the steps of first spinning the thermoplastic filaments, then cooling the spun filaments, and then conducting the cooled and spun filaments in a travel direction through a stretcher with primary air such that the primary air exits a downstream end of the stretcher with the filaments at a predetermined primary air volume/flow VP. The filaments and substantially all of the primary air are passed together as a flow from the downstream end of the stretcher into a diffuser. Secondary air is introduced into the flow at a secondary air volume/flow VS such that a ratio VP/VS of the primary rate VP to the secondary rate is equal to at least 4.5 and the primary and secondary air flow with the filaments in the travel direction through the diffuser.
