… 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… The process focused on the preparation of wet white leather, tanned using glutaraldehyde, a chromium-free tanning agent known for its potential biodegradability. Fresh bovine hides were used as the raw material. After standard …
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 PDFStudy on pickle-free tanning and environmentally-friendly beamhouse process by enzymatic unhairing and biopolymers Makoto MATSUMOTO1) , Yusuke SHIMADA2) Hyogo Prefectural Institute of Technology, Technical Support Center for Leather1)，3S LEATHER TECHNOLOGY CO.,LTD2 …
Open original PDF… wet processes using tanning agents with reduced chromium content or chrom -free tanning molecules associated with nanostructured agents; B: finishing processes through the use of nanostructured agents for the functionalization of lea- thers (functionalized …
Open original PDF… Initiatives such as the substitution of traditional tanning agents with chromium-free alternatives, coupled with more sustainable finishing treatments, represent a turning point for the sector [8]. Likewise, the implementation of modern manufacturing guidelines …
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 PDF… In this study, oligochitosan (OCS) was prepared from chitosan extracted from the roots of enoki mushrooms and chemically modified using reactive dye R19 and epichlorohydrin (ECH) to prepare a biomass-based chromium-free tanning …
