AbstractThe paper presents the results of research into glycolide/L-lactide copolymer (PGLA) fiber formation by wet spinning from solution. The selected process conditions led to fibers with a specific tensile strength of more than 35 cN/tex. Furthermore, ceramic nanoadditives such as hydroxyapatite (HAp) and β-tricalcium phosphate (β-TCP) were used to obtain fibers with osteoconductive properties. It was found that the ceramic nanoadditives reduced the specific strength of fibers (to 24 cN/tex for β-TCP and to 27 cN/tex for HAp). The paper also presents wide-angle X-ray scattering (WAXS) evaluation of the supramolecular structure of the fibers as well as their porosity parameters and microscopic structure. The obtained fibers were woven into a textile fabric with potential applications in biomedical engineering.
