| Résumé : |
Examination of any book on leather science will always talk about the collagen swelling effects seen at the secondary or tertiary level of protein hierarchy. The exact description and the prominence of which types of swelling exist in the material at specific parts of the process cycle can be left up to the academics to debate.
As with most science, the frustration that exists between technologists and the theoreticians are real. Like many leather scientific theories, the facts (that usually make perfect sense) and the reality seen in the liming or pickle drum are often confusing.
A common example of this is the description of the leading type of swelling that is seen during liming. The controls that the tanner uses to overcome this swelling often appear to be contradictory, or at the very least do not seem to equate to the effects that one would expect given the theory. |

- Revision of swelling : Lyotropic - Electrostatic
- Structure hierarchy
- Water
- Plumping
- Fig. 1 : A schematic representation of how the collagen triple helix opens when experiencing swelling effects
- Fig. 2 : At the fibre-bundle, or fibre level, the influx of capillary water (or maybe even bulk water) also has a profound effect, resulting in the hide and skin increasing size tremendously (plumping)
- Table 1 : Collagen has various water associations (Taken from Bienkiewicz, 1983) |
