Thermal bonded non-wovens are subjected to compression during their end-use performance in various technical and industrial applications. An attempt has been made to apply the previous theories of compression to formulate a simple two-dimensional (2D) micromechanical model of thermally bonded non-woven structures. The 2D model has incorporated the basic fibre parameters and properties including fibre volume fraction, proportion of free fibre length between two bonds, fibre modulus and an integral defining the orientation characteristics of fibres. A comparison is made between the experimental and theoretical pressure-thickness curves. The effect of fibre orientation characteristics and volume fraction on the compressional behaviour of thermally bonded non-wovens has also been investigated.
