Sustainable functional finishing for cotton fabrics using chestnut shell extract

Abstract

Owing to global environmental concerns, sustainable industrial processes have become a topic of signi cant importance in various elds. Chestnut shells are byproducts of agricultural and food industries; however, they include various health-bene cial compounds such as polyphenols and avonoids. In this study, the feasibility of using chestnut shell extract as a natural functional agent for textile nishing processes was investigated. The chestnut shell extract was prepared by boiling the inner and outer shells of chestnut in distilled water for 4 h. Subsequently, the extract was ltered, centrifuged, concentrated, and nally dried into powder form using a freeze dryer. The extract was then dissolved in distilled water at different concentrations and applied to cotton fabrics through a pad-dry-cure process.The nished cotton fabrics were investigated by scanning electron microscope, Fourier-transform infrared spectroscopy, etc. In addition, the antibacterial and antioxidant properties of the nished cotton fabrics were examined as functional properties. The results showed that the cotton fabrics nished by chestnut shell extract exhibited signi cant antibacterial, antioxidant, and deodorant properties when the concentration of the chestnut shell extract was above 10 wt% in the nishing bath.

Phenolic Compounds from By-Products for Functional Textiles

“…A dye obtained from Keemun black tea, with theaflavins as the major polyphenol in its composition, was able to inhibit >99.9% of S. aureus in flax fabric [59]. Aqueous chestnut shell extracts, having condensed tannins and gallic and ellagic acids, were able to achieve percentage inhibitions of >99.9% against S. aureus and K. pneumoniae in cotton fabric [66,67]. Several other dyes were also able to achieve over 90% inhibition against microbes.…”

Coloring and functional properties of cotton and wool fabrics treated with aronia (Aronia melanocarpa) fruit and leaf extracts

“…Many researchers have investigated the textile dyeing and finishing potentials of coloring and functional agents extracted from different natural sources. It has been reported that bioactive compounds extracted from gallnut (Koh and Hong, 2014;Hong, 2021a), spent coffee (Koh and Hong, 2017;Hong, 2018a) and chestnut shell (Hong, 2018b(Hong, , 2021b) can be effective coloring and/or functional agents for textile treatment. However, the fabrics finished by natural compounds are known to show inferior durability in the functionality against laundry, oxidized aging, etc.…”

Bio-coloration and ultraviolet protection finishing of tussah silk using chestnut leaf extract and its thermodynamic study

“…The primary bioactive components of chestnut shell extract [13][14][15] are flavonoids and tannins. Numerous studies have delved into the potential applications of chestnut shell extract in textile dyeing [16][17][18] and its functionality, [19][20][21] although chestnut leaf extract research remains limited. According to figures from the Dandong Agricultural Bureau, the chestnut tree planting area in Dandong exceeds 1400 km 2 , with an annual output of more than 110,000 tons and a value of more than 800 million yuan.…”
