Abstract

A spunbonding apparatus capable of producing multicomponent spunbond filaments. The spunbonding apparatus includes a spunbonding apparatus comprises a spinneret discharging multicomponent filaments and a filament-drawing device applying a first force that is effective to attenuate the filaments. A force applicator stationed between the spinneret and the filament-drawing device is operative for applying a second force to the filaments that promotes filament splitting. Splitting may occur before the filaments enter the filament-drawing device, within the filament-drawing device, and/or after discharge from the filament-drawing device.
