Abstract: A process for producing a nonwoven fabric comprises the steps of a spinneret extruding a plurality of filaments, cooling the filaments with one or more cooling elements arranged below the spinneret, drawing the filaments in a drawing duct and laying the filaments on a movable support to form a nonwoven fabric. The process further comprises suctioning gas in a first suction device, heating the nonwoven fabric using a heated calender downstream of the first suction device to consolidate the filaments of the nonwoven fabric and to cause an increase in volume of the nonwoven fabric, suctioning gas below the movable support with a higher second suction speed, in a second suction device downstream of the heated calender, and suctioning gas below the movable support in a third suction region with a third suction speed lower than the second suction speed, by a shutter with one or more adjustable openings.

Abstract: The present invention relates to a process for producing a nonwoven fabric, comprising the steps of:
(a) extruding a plurality of filaments from a spinneret;
(b) depositing said filaments in a substantially not-crimped condition to make a nonwoven fabric on an element collecting the filaments;
(c) heating said nonwoven fabric to crimp at least part of the filaments, so that the volume of said nonwoven fabric is increased;
(d) bonding said nonwoven fabric;
wherein said filaments are at least bicomponent filaments.-

Abstract: Provided is a process for producing a nonwoven fabric. The process includes extruding a plurality of filaments from a spinneret, the filaments being at least bicomponent filaments; depositing the filaments to form a nonwoven fabric on an element collecting the filaments; performing a bonding of the nonwoven fabric; increasing the thickness of the nonwoven fabric by crimping at least part of the filaments by heating the nonwoven fabric; and, preferably performing a setting of the nonwoven fabric, wherein the bonding and the increasing the thickness steps are performed substantially simultaneously by means of a heated calendar. Also provided is the nonwoven fabric formed using the process and an apparatus for carrying out the process.
