… show that the tannability of leather can be improved by combining disaldehyde -degradation products with titanyl sulfate.The shrinkage temperature of DAS combined with titanium oxide sulfate increased by 9℃ compared with that of DAS alone . The dispersi on and fixation degree of collagen fiber network of leather tanned by the combination of degraded DAS and …

… GS powder) to achieve enhanced hydrothermal stability, durability, and resistance to environmental degradation as an alternative approach to Chrome tanning. Vegetable tannin reinforces crosslinking through hydrogen bonding and hydrophobic interactions while phenolic ligand phloroglucinol enables chelation with Al³z , improving its affinity toward carboxyl and amine groups in collagen. FT-IR and MALDI-TOF characterisation techniques confirm the formation of PHO-AL. Hydrothermal shrinkage …
