Different polybutylene terephthalate (PBT) yarns (multifilament PBT yarn, cotton core yarn and twisted viscose yarn, both with PBT in the core) were used. Textured PBT yarns have latent elastic properties, which become visible after the thermal treatment by the finishing process. The aim was to determine which of the constructional parameters is most important in analysing the shrinkage of fabrics after treatment, breaking elongation properties of all tested fabrics, and breaking elongation properties of woven fabrics before and after treatment. A multivariate statistical method ANOVA was used for the analysis. The results show that treatment was by far the most influential factor in the study of breaking elongation of all tested fabrics. When analysing the fabrics separately before and after treatment, the construction of the PBT yarn and the weave were found to be statistically significant parameters.20222022-09-26 15:33:49Članek v reviji141246UDK: 677ISSN pri članku: 0040-5000DOI: 10.1080/00405000.2021.1907971COBISS_ID: 59582211sl
