Airlaid Line Width and Speed Optimisation
topic
Airlaid production line economics improve with wider forming widths from 1.6 to 3.5 metres through increased fibre throughput per unit equipment investment, with line speed from 50 to 300 metres per minute determined by the forming head fibre capacity and bonder throughput, while web weight from 30 to 2000 grams per square metre is adjusted by forming head rotor speed and conveyor speed ratio within the limits of adequate web uniformity.
Role
Optimises the production economics of airlaid lines through the combination of maximum production width and speed that achieves required web quality, with forming head capacity being the primary constraint on line speed at any given web weight and the capital cost per unit production width being the key metric for evaluating airlaid equipment investment return for high-volume disposable hygiene product applications.
