Résumé : |
Denatured Starches I and II were obtained by single-oxidation and double-oxidation of acidic hydrolysing starch. Denature Starch II possessed more carboxyl groups and a smaller particle size than Denatured Starch I. The two denatured starches developed in this research and several typical fillers were applied to chrome-tanned crust leather. The contrasting results of filling showed that Denatured Starch II has some characteristics with obvious differences from other fillings. The leather sample filled with Denatured Starch II showed obvious sample filled with Denatured Starch I showed significant softness, large elongation, and low hypsochromic effects. The leather samples filled with Denatured Starch I and II showed low moisture contents, favourable water vapour permeability, and the morphological characteristics of fibre bundles. |
