Abstract

Green polymers have gained popularity in recent decades because of increasing pollution throughout the world. Poly (butylene succinate) (PBS) is an aliphatic polyester and a relatively new polymer. The application fields of its products when combined with the solution blow spinning (SBS), method may be expanded to textiles, food, packaging, filters, batteries, and biomedical products due to its outstanding biodegradability, processability, and thermal and chemical resistance. Therefore, this study focused on the SBS process as a PBS polymer solution to scale up the nanofibers manufacturing process to the commercial level. PBS nonwovens were produced using a SBS apparatus. The PBS solution-blown nonwovens were characterized using scanning electron microscopy. A full factorial design was used to test the data for statistical analysis to investigate how solution concentration, air pressure, and flow rate influenced average fiber diameter. The impact of the process control factors was examined using analysis of variance. The thickness, air permeability and contact angle values of the material obtained under optimum conditions were also measured. The results have shown that the solution concentration significantly influences the mean diameter. The optimum SBS production parameters factors were determined to be as follows: 9 % wt. PBS concentration, 4 bar air pressure and 80 mL/h feed rate. The smallest average fiber diameter was 156 nm and the greatest average fiber diameter was 315 nm on nonwovens obtained at different production parameters. The water contact angle of PBS nonwoven was 119°. The fast and economical SBS process, coupled with the environmentally friendly nature of the PBS polymer, may contribute significantly to the industrial-scale manufacture of nanofibrous nonwoven made from this polymer.
