Device for stretching filaments to form non-woven fabric

The invention relates to a device for stretching filaments to form a nonwoven fabric, comprising a nozzle carrier having an elongated drafting channel, the drafting channel comprising a filament inlet and a filament outlet, air nozzles generating a downward air flow being arranged opposite each other on both sides of the drafting channel, the air nozzles are communicated with the air chambers on the two sides of the nozzle bearing body through air channels, a rectifying device is arranged between the air channels and the air chambers, the rectifying device is provided with at least one rectifying chamber, and the rectifying wall of the at least one rectifying chamber is arranged to be partially breathable. The airflow is temporarily integrated in a small space through the space limitation of the rectifying chamber, the airflow flows out of part of the ventilation area along with the flowing of the airflow, and the process plays a similar'combing 'role on the airflow. 本发明涉及一种拉伸细丝以形成非织造布的装置，具有喷嘴承载体，所述喷嘴承载体具有长形的
