Stationary-pressure apparatus for producing spun-bond web |
摘要 |
Nonwoven spun-bond is produced by a stationary pressure apparatus in which the shaft below the spinneret has an inlet section followed by the downwardly converging intermediate section, a drawing section and a diffuser opening above the collecting belt through which air is drawn by a suction device. The process air velocity profile has an intersection point with the drawing value at the intermediate section and the distance between the intersection point and the spinneret is smaller than the distance between the intersection point and the bottom end of the drawing section.
