The effects of spinning conditions and additives on the physical and dyeing properties of poly(ethylene terephthalate) industrial yarns were investigated by analysing their supramolecular structures. Four poly(ethylene terephthalate) yarns for seat‐belt webbing were prepared with different formulations and under different spinning conditions. Instrumental characterisation of the internal morphologies and physical properties confirmed that the structural characteristics are influenced by the draw ratio, heat‐setting temperature and copolymer added, and that there are close correlations between the supramolecular structure and the physical and dyeing properties. In particular, the draw ratio was the most dominating factor, influencing both the mechanical properties and the dyeability.
