Fibre Trajectories in the Transport Channel of an Air-laid Nonwoven Process: Part II: Experimental Observations of Fibre Motion

A high-speed photographic technique was used to observe fibres in flight in the transport channel of the air-laying process. Analysis of photographs was carried out to obtain an understanding of the fibre behaviour throughout the transport channel. The results of the photographic analysis had reasonably good agreement with the main theoretical findings of the model developed in Part I, in respect of the trajectory of fibres within the transport channel of the air-laid web-forming process.
