MELTBLOWN PROCESS WITH MECHANICAL ATTENUATION

Cellulose containing dope is extruded through orifices and into a stream of gas moving in a direction generally parallel to the direction that the filaments are formed with varying degrees of mechanical attenuation provided to the filaments using a take-up device, such as a winder.

Beschreibung
Zusammenfassung:	Cellulose containing dope is extruded through orifices and into a stream of gas moving in a direction generally parallel to the direction that the filaments are formed with varying degrees of mechanical attenuation provided to the filaments using a take-up device, such as a winder. Selon cette invention, la cellulose contenant une solution à filer est extrudée par des orifices et dans un courant gazeux se déplaçant dans un sens généralement parallèle au sens de formation des filaments en variant les degrés d'atténuation mécanique sur les filaments au moyen d'un enrouleur ou bobinoir.
