These imporvements extend back down the supply chain to the farm and forward to the leather user.These changes stem from a better awareness of economic requirements and changes in market demands. There is a trend for industry in general to work or conform to quality standards. These include surch managemement systems as Total Quality Management (TQM), ISO 9000 and to a lesser extend 'just in time' management. Whether you believe in these types of systems, or even in the philosophy behind them, it is likely that they are in operation with the supply chain in which you function. Whatever the case, the leather industry is rapidly evolving from what has traditionally been considered a dirty, low tech industry to one which is dynamic and environmentally aware. The industry is utilizing the latest management methods and production techniques. As the demand for still tighter controls over processing increases, so must the technology used to monitor the processes improve. BLC is operating a number of projects which aim to develop instruments or methods for better process control. These include the use of an 'electronic nose' for the early detection of raw-stock putrefaction, a device for monitoring pH and temperature within a closed vessel, and methods for improving the consistency and quality of wet blue grading. This paper discusses approaches being investigated at BLC to improve process control and hence serve as valuable tools for the leather sector.

Uses and applications of microscopy in the leather industry - A practical approach to process control and leather manufacture / Rachel Garwood in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXX, N° 11 (11/1995)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXX, N° 11 (11/1995) . - p. 337-346 Titre : Uses and applications of microscopy in the leather industry - A practical approach to process control and leather manufacture Type de document : texte imprimé Auteurs : Rachel Garwood, Auteur Année de publication : 1995 Article en page(s) : p. 337-346 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Microscopy has a wide range of applications within the leather industry. Recent research carried out by BLC and industrial technical problems received by the organization have highlighted the usefulness of microscopy, for monitoring and developing leather processes, fault diagnoses and process control. Currently, BLC routinely uses three types of microscopes : a stereo observation microscope, a conventional light microscope and a scanning electron microscope (SEM). The stereo microscope provides instant information on the general characteristics of samples with minimal sample preparation. The ability to view whole samples has enabled problem to be solved and processes checked within a matter minutes. Sample preparation is slightly more involved for the light microcope as sections are required. The sections can be selectively stained to highlight skin and processing components, allowing their break-down/removal from and penetration into the skin structure to be followed. The SEM provides a wider magnification range than the other two techniques. Conventionnally, samples had to be dry in order to be assessed using the SEM. A relatively recent addition to this instrument is the cryo-chamber which now enables the analysis of "wet" samples to take place. This tachnique has been used by BLC to follow opening up, fatliquor location and the effect of enzymes on fat cells. Microcopy analysis has also been linked to analytical techniques such as x-ray analysis and fourier transform infrared spectroscopy (FTIR) to provide additional information on the chemical nature of samples.
