Studysummary This study developed a biodegradable nonwoven textile using a starch-based biopolymer and fruit extracts, resulting in materials that are stronger, more hydrophilic, and capable of releasing beneficial compounds over 72 hours, positioning them for potential use in medical, healthcare, and cosmetic applications. Our plain-language summary of this paper — not a Tressless recommendation.
This study investigates the enhancement of spun-bonded nonwovens using polyphenol-rich extracts from blueberries and elderberries, applied via aerographic spraying to BIOPLAST® fabrics. The treatment significantly improves mechanical properties, with a 38% increase in tensile strength and a 50% increase in elongation at break, while also making the surface more hydrophilic. The modified nonwovens exhibit a controlled release of polyphenolic compounds over 72 hours, suitable for biomedical, healthcare, and cosmetic applications. The approach is environmentally friendly and aligns with green chemistry principles, offering a sustainable method to introduce bioactivity into technical textiles.
