The production and physical and thermal characterization of polybutylene succinate multifilament yarns

Abstract

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) based polymer into multifilament yarn by melt spinning method and examine the effect of different winding speeds on the textile values of PBS yarns. In this context, multifilament yarns with round cross-sections were produced at four different winding speeds. The linear densities (dtex), elongations at maximum load and tenacities of the produced yarns were determined. The thermal characterization of PBS yarns were carried out by differential scanning calorimetry (DSC). The cross-sectional images of PBS filaments were taken and their diameters were measured, on an optical microscope. The results showed that as the winding speed increased, the elongation and dtex values decreased, while the tenacity and crystalinity values increased. It was determined that PBS filaments have smooth round cross-sections.
