Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical fiber processing, specifically to a cooling device for waste heat recovery of spunbond production line. BACKGROUND

[0002] The melt stream from the cooling air box releases a large amount of solidification heat, which must be heat-exchanged, so the melt is cooled and blown about 10mm away from the spinneret to make the melt solidify into a yarn in the forming process. Therefore, a cooling air device is installed below the spinneret, which requires uniform cooling of each single yarn within a certain length. The temperature, speed and air outlet uniformity of the cooling air have a significant impact on the normal production and product quality.
