Special Issue Information

Dear Colleagues,

Nonwoven is a unique material forming method, which can directly form polymer chipping, staple fiber or filament into fiber products with specific properties and planar structures through a variety of fiber web forming methods and consolidation technology. Thanks to the maturity of and innovations in nonwoven technology, the nonwoven industry has entered a new development period represented by superfine fibers, nanofibers, and bicomponent fibers. The development of new fibers and nonwoven production technology has become a research hotspot around the world, and various new nonwoven processes are constantly emerging, such as electrospinning, flash spinning, solution blowing, bubble electrospinning, etc. These processes are playing an increasingly important role in the fiber material forming field. In addition, some nonwoven processes can be combined with each other, producing new nonwoven processes. In recent years, intelligent manufacturing has been integrated into nonwoven technology, and many achievements have been made in fields such as automatic control, defect detection, and simulation, which will play an important role in the future.

Recognizing the importance of experimental research, mechanism characterization, and theoretical simulation in the new nonwoven process and the properties of new nonwoven fiber material, this Special Issue of Polymers invites contributions addressing several aspects of new nonwoven processes, such as the forming mechanism of superfine fibers, nanofibers, and bicomponent fibers, the experimental means and methods, fiber modification, characterization methods of physical and chemical properties, simulation of new nonwoven processes, interface design and properties of nonwoven composites, intelligent manufacturing in new nonwoven processes, etc. The above list is only indicative and by no means exhaustive, and any original theoretical or review article on new nonwoven processes is welcome. We hope that these contributions will involve the application of new nonwoven processes in environmental protection technology, clean energy, bioengineering, and smart wearables.

With the continuous improvement of the standard of living, people are increasingly inclined towards natural, green, and environmentally friendly products. Plant-based products that are safe, natural, non-toxic, and beneficial to human health are often more favored. Poly(lactic acid) (PLA) is a polymer obtained through lactate polymerization using renewable plant resources such as corn and has excellent biocompatibility and biodegradability. It is widely used in the field of food packaging. Wormwood oil (WO) is an oil extracted from the stems and leaves of Artemisia plants, and it has broad-spectrum antibacterial properties. In this article, through electrospinning technology, wormwood oil was directly incorporated into PLA, giving the PLA nanofiber membrane antioxidant and antibacterial functions. Various parameters such as voltage (11 KV, 13 KV, 15 KV), spinning solution concentration (8%, 10%, 12%), distance (15 cm, 17 cm, 19 cm), and feeding rate (0.4 mL/h, 0.5 mL/h, 0.6 mL/h) were explored, and the resulting spun fibers were characterized. Through SEM characterization, it was found that when the spinning voltage was 13 KV, the spinning solution concentration was 10%, the distance was 17 cm, and the feeding rate was 0.5 mL/h, the nanofiber membrane had a smooth morphology without bead formation, with an average diameter of 260 nm. The nanofiber membrane was characterized using FTIR, TG, and SEM, confirming the successful incorporation of artemisia essential oil into PLA. The prepared antimicrobial nanofilm was subjected to antimicrobial testing, and the results showed that as the concentration of the essential oil increased, the inhibition zones also increased. When wormwood oil concentration was 4%, the diameter of the inhibition zone for Staphylococcus aureus increased from 1.0 mm to 3.5 mm, while the diameter of the inhibition zone for Escherichia coli increased from 2.0 mm to 4.5 mm.
