There are significant problems in the production, use and waste management of petroleum-based polymers due to the increasing plastic waste problem, exceeding limit of the greenhouse gas emissions and decreasing fossil resources. The textile sector is the second sector that causes the plastic waste problem after the packaging sector. About 65% of the total yarn produced in the textile industry consists of yarns obtained from petroleum-based polymers. Biopolymers come to the fore in studies carried out within the scope of sustainability philosophies such as using of renewable raw materials, recycling at the end of their life and decomposition without harming the nature. In this study, it is aimed to produce biobased and biodegradable polybutylene succinate (PBS) polymer into multifilament yarn by melt spinning method and examine the effect of different winder speeds on the textile values of PBS yarns. In this context, multifilament yarns with round cross-sections were produced at 4 various winder speeds. The linear density, elongation (at Fmax) and tenacity of the produced yarns were obtained by performing analyzes, and also cross-sectional images of the filaments were also taken. The results suggested that the elongation (at Fmax) and dtex values decrease, and the tenacity value increases due to increasing winder speed. Additionally, the cross-section properties of the PBS multifilament yarn are smooth round sections and that the filaments in a yarn have similar diameters to each other.
