Abstract:
The invention relates to a method for producing a nonwoven fabric from fibres, wherein the fibres are spun by means of at least one spinneret, are cooled and then deposited on a collection device to form a nonwoven web. The nonwoven web undergoes hot fluid bonding during at least two consecutive bonding steps. In a first bonding step, the surface of the nonwoven web is subjected to a hot fluid and, in a second bonding step, the surface of the nonwoven web is also subsequently subjected to a hot fluid and, in addition and at the same time, surface pressure is exerted on the nonwoven web.
