Fibrous nonwovens comprise of fibres or filaments bonded by various methods. Depending on the mode of fabric formation these fibres may be entangled; this affects the physical properties of the bulk structure. Estimating the degree of entanglement based on relative fibre arrangement in such structures is highly challenging. In this paper, fibre-to-fibre interactions within simulated fibrous assemblies are analysed using topological and geometrical principles as a means to quantify entanglement. The underlying theoretical framework in which splitting number is used to characterise entanglement has been previously described [1]. A detailed algorithm and its practical application for the estimation of fibre entanglement are reported based on Dynamic Recursive Splitting (DYRES).
