This paper considers how a broad range of fibres behave in hydroentanglement. It is based upon results from a new pilot line at Courtaulds Research in the UK which uses the Perfojet hydroentanglement system. The fibres studied were cotton, polyester, rayon and Courtaulds new solvent spun cellulosic fibre Tencel. The experimental procedures of the study and the trial results indicating fibre performance in hydroentanglement are detailed. The influence of fibre type, length, cross-section and fineness are discussed. The hydroentanglement efficiency of all the cellulosic fibres was good. Tencel fibre gave good wet and dry fabric properties in comparison with the other cellulosic fibres studied. Polyester fibres tended to be more difficult to entangle, resulting in bulky, less well consolidated fabrics but with good wet strength.
