… 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 PDF… This device can be used for tanning production staff to quickly judge the effect of each chemical in the process and improve production efficiency.
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 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 …
Open original PDFThe production of leather generates a not inconsiderable amount of by-products; only about 25% of the incoming raw material weight (cattle hides) is fi nally commercialized as genuine leather. The rest are protein …
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 PDFInnovative Chemically Modified Natural Tannins (CMNT) for eco-friendly tanning have been developed within the LIFE I’M TAN project co-financed by EU, for the production of environmentally sustainable leather for footwear, handbags …
Open original PDFThe following paper describes technology for the recovery and recycling of unused chemicals from both the unhairing/liming and pickle/tanning processes for chrome tanned leather. The technique was investigated by BIOSK at pilot …
Open original PDF… In addition, an overall overview of the tanning, retanning and fi nishing processes and the chemicals involved with respect to the bio- based content have been carried out: The investigators focused on the estimation …
