| Résumé : |
A matched-side comparison has been carried out between a one-bath and a two-bath unhairing system, using 8 sides per treatment. After unhairing separately the sides were chrome tanned, retanned and fatliquored together.
Comparison of the physical properties of the crust leathers showed that the two unhairing systems gave very similar and acceptable results. However, the leathers produced from the two-bath unhairing system showed definite advantages as far as grain cleanliness, lime draw and growth marks were concerned. Slightly firmer leather was obtained from the two-bath system, with a correspondingly tighter grain break. It is felt that the softness aspect can easily be corrected by slight adjustments to the post-tanning operations.
This trial has shown that the age-old saying that "Leather is made in the beamhouse" is still valid and warrants reinvestigation by tanners who wish to improve on the grain quality of their raw material. |
