Abstract

A method of manufacturing absorbent structures e.g. menstrual towels, nappies, surgical dressings and wiping towels, wherein a liquid- absorbing material e.g. in the form of a powder, is secured to a support e.g. a film or fibrous pad by depositing a binding agent for example poly(vinyl alcohol), particularly in the form of an aqueous solution or dispersion. In one procedure after the liquid-absorbing material and the binding agent have been applied to one pad, a second pad is applied to form an integral structure with the binding agent and in another procedure the liquid-absorbing material is incorporated between two pads, and a liquid binding agent is applied to the external surface of one pad and percolates through to form an integral structure.
