Surfactants -- BiodégradationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Although there have been many discussions of the need for and development of biodegradable surfactants, ranging from oversimplified news accounts to the highly detailed technical paper, it is felt that there is a need to deal with the nature of pollution itself and the relationship of surfactants to the nation's overall waste disposal system. Accordingly, we shall look quickly at the nature of wastes, waste disposal, types of pollution, and the nature of surfactant pollution. Then we shall progress to the subject of biodegradability - what it is, how it is measured - and finally examine the qualifications of commercially available types of biodegradable surfactants.

Titre : The development of a standard accelerated aging test for measuring the durability of leathers used in musical instruments Type de document : texte imprimé Auteurs : Harley Piltingsrud, Auteur ; Jean Tancous, Auteur Année de publication : 1987 Article en page(s) : p. 285-300 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This study was intended to investigate the reasons for the widely varying performance of leathers used in organ building during at least the past 40 years, as well as to attempt to find a method for predicting the longevity of particular leather samples and to identify types of leather processing that produce longlasting leathers. Results of the study indicate that there are leathers produced using modern tanning methods which are adequate for long-term use in pipe organs, and that they can be identified using a modification of Cheshire's SO2 and O2 bomb method.

Peaux brutesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hair-saving processes for bovine hides are being applied in tanneries in several countries to replace traditional hair burning systems. The factors that are taken into account when using this unhairing technique are :
- the need for a pelt that is suitable for the production of different types of leather
- a reduction in the effluent load arising from the beamhouse
- the recovery of the partially degraded hair as a solid waste with potential industrial applications
It is well known that the organic matter, the sulfide ion content and the presence of suspended solids in the liquid effluent is greatly dependant on the unhairing process employed. Within the sulfide unhairing system there are problems associated with toxicity, odour and effluent treatment.
Hydrogen sulfide is a highly toxic gas, and can be liberated from within the unhairing process and from effluent treatment. In extreme cases it has led to the death of workers, and in the wider environment creates an odour within the tannery surroundings which causes associated complaints. The acceptable maximum concentration in the work environment, in which a worker can remain for 8 hours/day and 5 days/a week, is 10 cm3 H2S/m3 (15 mg/m3) without suffering physical damage.
The enzymatic removal of intact hair offers a suitable alternative to destructive sulfide unhairing. However, interest in the enzyme unhairing process cornes and goes. This is because of difficulties in managing the process, mainly because the proteolysis cannot be accurately focused and controlled. Essentially, the enzyme activity is not restricted to the function of hair removal, but also affects the structure of the dermis. The grain layer is therefore partially digested hence there is a decrease in the quality of the grain structure in the final leather. Enzyme unhairing remains a fascinating concept, but is full of difficulties.
Nevertheless, the problems and costs of treating effluent to acceptable standards are considerable. If hair could be removed intact without using sulfide, then there would be a significant easing of techniques, capital equipment and power requirements to achieve discharge limits. In addition, the volume of sludge would be considerably reduced, with the hair remaining as a new clean raw material with many potential ourlets.Note de contenu : - The epidermis as a diffusion barrier

ExportationsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hides &nd skins represent up to 15% of the value of the carcasses and as such consitute one of the most valuable 'cuts' off the animal, comparable with rump steak. It is therefore somewhat surprising that skins are perceived as a by-product of the meat industry.
It is important to firmly establish that skins and hides are seen as a co-product of the meat industry.
In order that the UK and European leather industry can compete favourably in the world market place, it has risen to meet the demands of the quality end of the market place, it has risen to meet the demands of the quality end of the market. As such this requires a very high standard of quality in the raw material. The ability to meet these demands is being compromised by a belief that skins are not economically important and this results in pre- and post-mortem damage. Downgrading of skins and hides as a result of this damage is costing the UK tradt £50 million alone, and Europe £600 million.Note de contenu : - Anti-mortem factors
