… This work demonstrates that á-amylase-coupled ultrasonic extraction efficiently releases polysaccharides, polyphenols and saponins from longan seeds; selective periodate oxidation converts these extracts into a novel, biodegradable, chromium-free tanning agent, providing a …
Open original PDF… In this study, we demonstrate that the mycelium can be successfully tanned with chromium-free tanning method to improve its structural stability, and significantly improved physical mechanical properties, including tensile strength and tear strength …
Open original PDF… Further, Physical strength and Organoleptic properties of the tanned leathers are comparable to the commercial leathers. The combined tanning strategy demonstrates an ecofriendly, chromium-free pathway capable of delivering leathers with superior performance and …
Open original PDFTo mitigate chromium pollution in leather manufacturing, we developed a novel biomass-based chrome-free tanning agent (polyphenol–cyanuric chloride derivative, PCC) by grafting cyanuric chloride (CC) onto tea polyphenol (TP). Exploiting the pH …
Open original PDF… However, keeping the chrome-free leather processing in mind, researches are in progress to develop high-performance titanium based tanning agents comparable to conventional chromium tanning agents. Therefore, the current review work concentrates in …
Open original PDFThe leather industry faces significant environmental challenges arising from the widespread use of petroleum-derived synthetic retanning agents, which increase pollution loads and introduce free formaldehyde into finished leather. This study addresses these concerns …
Open original PDF… A pit-based pretanning followed by a pickle-free tanning system was identified as the most suitable method, ensuring preservation of the skin’s structural integrity. In contrast, drum-based pre-tanning caused substantial …
Open original PDF… The efficiency of fatliquoring was systematically evaluated and compared in both chrometanned and chrome-free tanned leather systems to establish the versatility of the developed polymer. When applied to chrome-tanned leather, the developed …
Open original PDF… This work proposes a new, original raw hide processing flow diagram in which dyeing, retanning, and filling are performed before the main tanning and fatliquoring with chromium compounds. A mechanism for intensive mass transfer …
Open original PDFThe leather industry has long faced the dual challenges of chromium pollution and solid waste management. This study proposes an innovative strategy that not only achieves chrome-free tanning by adopting a novel pH …
