Tanning Treatment TRIZ Cases
- Hide Preservation Without Salt Curing
A hide preservation method uses drying and pickling steps to produce flexible, dry hides ready for rehydration.
- Pressure Tanning Leather with Carbon Dioxide
Compressed carbon dioxide treats hides under pressure to control pH and deliver tanning agents uniformly.
- Animal Hide Dehairing Enzyme Sequence
Sequential enzyme and polysulfide treatment breaks down hair on animal hides, resolving the trade-off between removal effectiveness and processing time.
- Lignin-Modified Polyphenolic Tanning Agent for Leather
Lignin-modified polyphenolic product improves leather hydrothermal stability and organoleptic properties through condensation reactions.
- Aldehyde Tanning Bath with Non-Ionic Surfactants
A tanning bath combines short-chain aliphatic dialdehydes with non-ionic surfactants to cross-link collagen polypeptide chains.
- Oxidative Liming Process for Metal-Free Leather Production
An oxidative liming process using hydrated lime and hydrogen peroxide removes hair from hides without sulfides.
- Leather Retanning Agent Using Alpha-Olefins
A leather retanning agent combines alpha-olefins with dicarboxylic anhydrides to deliver softening and stability.
- Aqueous Float Composition for Leather Treatment
Copolymer and silicone compound treatment in aqueous float prevents diffusion-based inhomogeneities and mottled coloration.
- Chrome Tanning Process with Controlled Temperature and pH
A tanning process controls temperature and pH to maximize chrome absorption in animal hides.
- Electrochemical Tanning Process for Leather Production
An electrochemical tanning process applies an electric field to accelerate ion diffusion, reducing chemical waste and production time.
- Tanning Leathers with Triazine Derivatives
Triazine derivatives cross-link collagen fibers to improve hydrothermal stability and dyeability without retaining toxic residues.
- Drying Unit Aperture Segmentation for Uniform Pelt Airflow
Segmented aperture rows distribute airflow evenly across pelt zones, preventing uneven drying and quality loss at high blower speeds.
