Abstract (en)

[origin: DE19923344A1] The surface properties of fibers (2) in a melt blown batt (10) are modified by spraying an additive (14) on the fibers as they emerge from the spinneret nozzle (8). The additive can be undiluted or a solution or emulsion in water, which also acts as coolant (16) as it evaporates to leave the additive on the fiber surface. Independent claims are also included for the following: (a) an analogous process for film extrusion; (b) plant for the application of surface modifiers to melt blown fibers; and (c) an analogous plant for film.
