摘要

With the growing emphasis on sustainable textile processing, the development of eco-friendly functional finishing agents derived from natural sources has emerged as an important research focus. Agricultural and food industry by-products are valuable raw materials, contributing to environmental protection and resource circularity. Chestnut (Castanea crenata) shells, which are rich in polyphenols, flavonoids, and tannins, exhibit notable antioxidant and antimicrobial properties; however, they remain underutilized because their bioactive compounds are poorly extractable in the raw form. Therefore, this study aimed to enhance the release and extractability of bioactive compounds in chestnut shells through Aspergillus oryzae-mediated fermentation for use in functional textile finishing. Chestnut shell biomass collected from local farms was subjected to solid-state fermentation, and aqueous extracts were prepared and applied to cotton fabrics via a pad–dry–cure method. The effects of fermentation time on total flavonoid content (TFC) and total phenolic content (TPC) were analyzed to determine optimal fermentation conditions for functional finishing. The treated fabrics were then evaluated for their antioxidant and antimicrobial performance. Fermentation significantly increased TFC and TPC levels in the extracts, leading to enhanced textile functionality. Fabrics treated with fermented extracts exhibited strong antimicrobial activity, achieving > 99.9% and 94.3% reduction of Staphylococcus aureus and Klebsiella pneumoniae, respectively, along with an antioxidant activity of approximately 93%, significantly outperforming untreated control fabrics. These findings highlight the potential of fermented chestnut shell extract as an effective and sustainable bio-based finishing agent for functional textiles.
