| Résumé : |
With the growing demand for high-quality full-grain leathers and the necessity to minimise costs of re-working, the need for accurate and reliable sorting of semi-processed stock is becoming increasingly important.
During recent studies at the British Leather Confederation,a wide range of high- and low-technology approaches has been investigated to determine whether they have any potential to detect grain damage. This has led to the development of the 'Sortassist' process based on a decolorisable pigment that effectively highlights grain faults on wet blue(75 to 85 percent detection rate) or pickled stock(over 95 percent detection rate).
The pigment formulation can be applied either manually or by drum at pH>4. After grain sorting, the pigment is decolorised and chemically destroyed by a short acid-treatment step at pH<3, prior to further processing of the stock. |
