A method for managing adsorbent and or absorbent particles within a manufacturing process whereby the particles 3 are dispersed onto the top surface of an air permeable substrate 4, the particles being in the range of between 0.01 µm to 500 µm. The particles are subjected to an atmospheric pressure dielectric barrier discharge process to de-agglomerate the particles whilst they are substantially in contact with the air permeable substrate, such that the particles become located substantially below the top surface of the air permeable substrate. The particles within the air permeable substrate may then be consolidated by passing hot water vapour and/or steam through the substrate. After the hot water vapour or steam treatment, mechanical pressure map be applied to the substrate to ensure consolidation. Alternatively, hot air may be passed through the substrate at a pressure greater than atmospheric pressure. The particles may be organic or inorganic, and can be activated carbon, metal organic frameworks, sodium polyacrylate, zeolites etc. Preferably, the substrate is a non-woven fabric, paper, an open cell foam, woven fabric or felt. The inclusion of adsorbent/absorbent particles may be desirable in hygiene products such as infant diapers, adult incontinence products, feminine hygiene products etc. |
