Abstract
A fiber forming device is disclosed that is well suited to producing nonwoven webs having excellent barrier properties. In one aspect, the fiber forming device can be used to produce meltblown webs or coform webs. The fiber forming device includes a die head containing multiple rows of polymer nozzles for forming fibers. Air flow paths are positioned on either side of the rows of polymer nozzles. In addition, an air flow path is positioned in between the rows of polymer nozzles. The air flow paths produce an attenuating gas stream that attenuates fibers being produced by the polymer nozzles and directs the fibers onto a forming surface for forming nonwoven webs.
