MarketingIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In 1927 John Arthur Wilson stated: “The entire value of leather lies in its properties, and if these are not clearly defined, trade is hampered.” Today, improvement in the performance and aesthetic properties of synthetics makes it harder to differentiate between leather and substitute materials and there is a lack of information about leather at point of retail. Erosion of leather identity and challenges to the image of the industry potentially detract from the value of leather as a component material in the mind of consumers. Global brands, and specifically component branding is a rapidly growing segment of marketing today and the suggestion is made that the leather industry carefully consider the potential benefits of marketing leather as a component brand supported by a certification program. There are a number of international organizations addressing some of the immediate challenges facing the industry and some are also involved in various aspects of marketing support of leather. This is encouraging, but it is suggested that the leather industry could benefit from specific coordination of this effort through appropriate structures and should further consider working towards a global component branding strategy for leather with direct marketing to the end consumer. This is not a new call, it echoes previous John Arthur Wilson lectures, but perhaps now the time is right to do something about it.

ViscoélasticitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The viscoelastic properties obtained from tensile stress-strain curves on leather and a number of poromerics are compared. It is found that a unique correlation exists for all shoe upper materials between the energy input to a stress-strain cycle and the hysteresis in that cycle.
The amount of tension-set at a particular strain for leather is larger than for the poromerics and this gives leather an enhanced comfort property. The paper shows how this initial set is related to the amount of stress softening (difference between first and subsequent extension curves) in the material. The change of tension set with time of recovery, after extension to a particular strain, is shown to be similar for leather and poromerics.Note de contenu : - Stress-strain properties

Titre : The water authority's service to industry Type de document : texte imprimé Auteurs : D. A. Bailey, Auteur Année de publication : 1986 Article en page(s) : p. 77-82 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The Water Authority's service to industry can be summed up fairly briefly ; it provides a supply of water for manufacturing processes and also for personal use by the workforce and subsequently arranges for its collection and suitable disposal after use together with a controlled level of added contamination. That is a simplified picture but, clearly, the reality is rather more complicated and one can anticipate a few questions.
On the supply side, which can be from the mains or a river or both, what is the quality ? What is the cost ? What is the reliability ? Also, on the disposal side, what are the conditions and what is the cost ? These are some of the matters on which I will try to provide information.
In order to make the main services available the authority must also attend to other responsibilities which constitute an important part of the overall service. These include the protection of surface and underground resources, i.e. reservoirs, rivers and streams, estuaries and tidal waters. It must also control some of these resources, to some extent, to avoid flooding and to supplement river flow during dry spells. In undertaking its multiple roles the water authority must operate within a tangle of legislation and other constraints as illustrated in Fig. 1.
A paper which I presented to the Northampton Group in 1976 dealt with the disposal of tannery wastes in relation to a Wather Authority's requirements. That paper explained why various conditions needed to be imposed and also provided some suggestions on how to meet those requirements. A second paper to the SCI explained the much wider role of the Water Authority. Much of what I said then remains relevant today but, since the publications are readily available for anyone still wishing to obtain the wider view, it would be wasteful now to go over the same ground.
During the ensuing nine years there have been quite a few changes, for example, more legislation, bulk transfers of water and alterations in the methods of charging customers. The objects of the present paper is to consider these changes in relation to their impact upon industry.En ligne : https://drive.google.com/file/d/1g9qXxpIfhG_mrytVy4m7XR3z4JwA6rbH/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9210

Transition de phaseEn physique, une transition de phase est une transformation du système étudié provoquée par la variation d'un paramètre extérieur particulier (température, champ magnétique...).
Cette transition a lieu lorsque le paramètre atteint une valeur seuil (plancher ou plafond selon le sens de variation). La transformation est un changement des propriétés du système.
Vapeur d'eauIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A water-based thermally-responsive polyurethane (TRPU), based on the crystalline soft segment from the reaction of polycaprolactone diol (PCL) with isophorone diisocyanate (IPDI) and the crystalline hard segment from the reaction of IPDI -1,4-butanediol (BDO) together with dimethylolpropionic acid (DMPA), was synthesized and used in water vapour permeable leather finishing.
Differential Scanning Calorimetry (DSC), Dynamic Mechanical Thermal Analyzer (DMTA), water swelling and water vapour permeability (WVP) were measured to evaluate how the structure of PU and the temperature influence the WVP of PU films and finished leathers.
In contrast to common polyurethane elastomer (PUE) with an amorphous reversible phase, the TRPU with a crystalline reversible phase shows a phase-separated structure and a phased transition temperature (Ttrans) at normal use temperature. The water swelling and water vapour permeability of both TRPU film and finished leather are found to depend on the inner structure of the polymers and the temperature. When the temperature exceeds the Ttrans, a significant increase of WVP from 4100g/m2/day to 10500g/m2/day was observed for finished leather in spite of some decrease of WVP compared with un-finished leather. Leather finished with common PUE appears to have a low WVP and only a slightly increased value over the temperature range.Note de contenu : - EXPERIMENTAL PROCEDURE : Material, preparation of polyurethane and testing - Film casting and leather specimen preparation - Differential Scanning Calorimetry (DSC) and
