A web of gray cotton fibers (12) is entangled by passing it under a series of low pressure liquid nozzles or jets (18) which are oscillated in a direction transverse to the direction of travel of the web. The entangled web (24) is then subjected to a cotton scouring step, and then dried, to produce a strong coherent nonwoven fabric that requires no resin binder and has a high absorption capacity for water. Particular parameters of liquid pressure, frequency and amplitude of oscillation of the nozzles or jets and energy transferred from the jets to the fibres have to be maintained. |
