A method is provided, for dissipating and entrapping super absorbent polymer particles (11, 12, 13, 14) within air-permeable, non-woven structures (100), for use in the construction of absorbent articles (600). The method comprises the steps of: (i) of constructing an air-permeable, non-woven structure (100) comprising at least first (1), second (2) and third (3) layers of non-woven fabric, each said layer having void spaces of differing size defined therein (ii) dispersing absorbent particles (11, 12, 13, 4) onto an external surface (10) of the highest numbered layer of said air-permeable, non-woven structure (100) formed in step (i) and (iii) dissipating the dispersed absorbent particles (11, 12, 13, 14) within the air-permeable, non-woven structure (100) by applying an external energy source acting upon the absorbent particles (11, 12, 13, 14) in a direction substantially normal to the plane of the external surface (10) of the air-permeable, non-woven structure (100).
