In recent years polybutyleneterephthalate gained on importance as a special polyester fibre characterised by high elasticity. The textured polybutyleneterephthalate multifilament yarn is competitive with polyethyleneterephthalate and polyamide yarns combining their both good properties. It can be used as a core in the core spun yarns being an important alternative to expensive and for processing more demanding elastane yarns. Such yarns are new on the market and their dyeing has not been researched yet. All the conditions for developing latent elasticity of polybutyleneterephthalate yarns are also not revealed so far. The aim of our research is to determine the optimal conditions of dyeing the textured polybutyleneterephthalate filament yarns as well as the core spun polybutyleneterephthalate/viscose yarns regarding the best dyeability, reproducibility, colour fastness, economical procedure and ecological acceptability with concurrent following of the textile mechanical and structural properties. By the determination of all of these parameters, especially the optimal dyeing procedure and the development of latent elasticity behaviour, it would make easier for the user of our research project to sell these new yarns, eventually also coloured, and by that also launching on the wider global market.
