The meltblown method is a common method to produce micro and nanofibers, and these fibers offer high surface area and good insulation properties with their lightweight structures. The rapid growth of the nonwoven fabric market produced by meltblown indicates that the demand for innovative products in this field is increasing and will offer greater economic opportunities in the future. This study aims to investigate the morphological and mechanical properties of nonwoven fabrics produced by meltblown technique, blends formed with polypropylene (PP), and a new biodegradable polymer, poly (butylene succinate) (PBS). In the research, monofilaments with different PP and PBS ratios were prepared and their production was carried out as meltblown technology. After the production process, the physical properties of the samples such as fiber diameters, air permeability, unit weights and tensile properties were examined. The results show that the fiber diameters decrease inversely proportional to the PP ratio, increasing air permeability. The 20PBS/80PP sample has the highest air permeability, while the 100PP sample reaches the highest unit weight. Strength tests reveal that the increase in PP increases the tensile strength but causes the elongation values ​​to decrease. This shows that PBS offers a potential contribution to improve the material properties but affects the fiber production stability and reduces the mechanical properties. In conclusion, the findings obtained in the study emphasize the importance of carefully selecting the material combinations to optimize the properties of meltblown nonwovens. This can contribute to obtaining more functional and environmentally friendly products in engineering applications.
