Extraction of Oil from Tannery Fleshings for Chamois Leather Tanning
Abstract The process of leather manufacturing produces vast amounts of solid waste annually (8.5 million tons worldwide), and most of the solid waste (80%) is produced in pre-tanning operations. The...
Physical Gelation of Gelatin Solutions: Effect of Gelatin Concentration, pH, Ionic Strength and Solvents
Abstract The effect of gelation conditions on the gelation of gelatin solutions was studied by rheological measurements. It showed that the gelling temperature (Tgel) increased with the increasing of gelatin...
Acquisition and Observation Methods of Threedimensional Leather Structure Based on Micro-CT
Abstract Components and working principle, parameters and data acquisition steps of micro-CT are introduced in detail. Taking the chrome-tanned leather for example, the images of each stage of the experiment...
Synthesis of Orthanilic Acid Modified Glyoxylated Melamine Resin with Improved Retanning and Thermal Properties
Abstract Amino resins have found important uses in leather manufacturing due to their selective filling properties. Conventional amino resins are produced from formaldehyde and result in an increase of formaldehyde...
