摘要： A method and associated apparatus for melt extruding a nonwoven web includes providing a plurality of fibers from an extrusion device. The fibers are conveyed through a diverging profile portion of a fiber drawing unit (FDU) that causes the fibers to spread and expand in the machine direction within the FDU. The fibers are then conveyed through a diverging diffusion chamber spaced from the outlet of the FDU to reduce the velocity of the fibers and further spread the fibers in the machine direction. The fibers may be subjected to an applied electrostatic charge in either the diffusion chamber or the FDU. From the outlet of the diffusion chamber, the fibers are laid onto a forming surface as a nonwoven web.

摘要： A nozzle is described for downwardly directing air from an air intake of a fiber draw unit into a longitudinal channel of the fiber draw unit for forming spunbond polymeric fibers. The nozzle includes an upper eductor connected to the fiber draw unit and a lower eductor adjustably connected to the fiber draw unit and below the upper eductor. The nozzle includes a nozzle cavity that narrows from a nozzle inlet to a nozzle outlet and includes a downward turn of 90 degrees or less. Air directed through the nozzle outlet flows in a direction parallel to a wall of the longitudinal channel.
