Abstract
For fibrillating a continuously conveyed, textile sheet material (3) a fluid under high pressure is delivered through a wide-slot nozzle (6) as a continuous fluid curtain (14) onto the sheet material (3). With this gentle way of fibrillating all types of fabrics may be fibrillated, in particular also light materials. The wide-slot nozzle (6) can be manufactured simply and inexpensively.
