Anatomy of halophile induced damage to brine cured cattle hides / Russell H. Vreeland in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. XCIII, N° 4 (04/1998)
[article]
Titre : Anatomy of halophile induced damage to brine cured cattle hides Type de document : texte imprimé Auteurs : Russell H. Vreeland, Auteur ; David G. Bailey, Auteur ; Sharon Angelini, Auteur Année de publication : 1998 Article en page(s) : p. 121-131 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In 1995 the United States exported over 20 million cattle hides with a market value of at least $1.4 billion dollars US. More than 70% of these hides are currently brine cured. The remainder are exported following chrome tanning as "wet blue stock". Brine curing has been an effective method for the preservation of hides for centuries. The process works well due to the fact that most degradative microorganisms are unable to survive the high concentrations of salt and the resultant low water activity present in the cured hide. Brine curing of hides does not, however, protect them from attack by halophilic bacteria. Extensive growth of these highly pigmented bacteria makes them readily visible to the naked eye. This condition is known industrially as 'red heat". It has long been believed by most hide processors, and tanners, that the presence of red heat indicates potential grain damage to the hide. Damage to the grain layer results in defective leather and significant financial loss to the industry.

Industrie -- Aspect de l'environnementIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Humans have always had a compassionate nature for animais. Since the dawn of time humans have interacted with animais as their food and as their companions. The domestication of wild animais to help manage their care in extensive/intensive food farm scenarios has taken hundreds of years to perfect. The welfare treatment of those animais has its ups and its downs. Cruel humans will be cruel to everything, and farmers are no exception. Kind humans have been compassionate and caring for animais since the beginning and will always continue to do so. Policy that moderates the cruelty and promotes the good practice is relatively recent.
Francis Brambell authored the Brambell report which introduced the concept of the Five Freedoms after Ruth Harrison wrote the Animal Machines' (Harrison, R., 1964 ; Brambell, 1965). In 1994, Webster (1994) was a ground breaker in the promotion of diagnosing different levels of care and furthered the concept of the 'Five Freedoms of Animal Welfare'. To be clear, this is not a statement saying this is the first time that mechanisms were put in place to treat animais with the right welfare - people have cared and treated animais correctly since the dawn of time. The Five Freedoms concept was the first time that policy, or discussion of policy, was taking place to improve the welfare of bad practitioners. The purpose of animal welfare is to correct the behaviour of the cruel.Note de contenu : - 'FIVE FREEDOMS' TO 'A LIFE WORTH LIVING' : Freedom from hunger and thirst - Freedom from discomfort - Freedom from pain, injury, or disease - Freedom to express normal behaviour - Freedom from fear and distress

ThermodynamiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this communication, sulfate dodecyl sodium (SDS)-induced thermodynamics and conformational changes of collagen were studied. We used ultrasensitive differential scanning calorimetry (US-DSC) to directly monitor the thermal transition of collagen in the presence of SDS. The results show that SDS affects the conformation and thermal stability of collagen very differently depending on its concentrations. At CSDS ≤ 0.05 mM, the enhanced thermal stability of collagen indicates the stabilizing effect by SDS. However, a further increase of SDS leads to the denaturation of collagen, verifying the well-known ability of SDS to unfold proteins. This striking difference in thermodynamics and conformational changes of collagen caused by SDS concentrations can be explained in terms of their interactions. With increasing SDS, the binding of SDS to collagen can be dominated by electrostatic interaction shifting to hydrophobic interaction, and the latter plays a key role in loosening and unfolding the triple-helix structure of collagen. The important finding in the present study is the stabilizing effect of SDS on collagen molecules at extreme low concentration.

Titre : Anisotropy of physical-characteristic functions of fur leather Type de document : texte imprimé Auteurs : E. Mäntysalo, Auteur ; M. Marjoniemi, Auteur ; E. Kemppinen, Auteur Année de publication : 1991 Article en page(s) : p. 133-140 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : According to recent investigations carried out in the LFLT the leather of fur has properties which must be considered anisotropic in nature contrary to those considered true random variables. Leather properties are functions of orientation angle and position coordinates of samples. Results are given for the leather of male and female blue fox (Alopex lagopus) and scan black mink (mustela vision) in the cases of breaking and elongation experiments. Four sample groups of fox leather (46 foxes) and one sample group of mink leather (21 mink) of different backgrounds as random subsets from the production of the year 1988 were investigated. All leathers were aluminum-tanned.

Titre : Annonying energy. Part II - Solar heating of dark leather Type de document : texte imprimé Auteurs : N. de Volder, Auteur ; J. Levy, Auteur ; M. Hallmanns, Auteur Année de publication : 2007 Article en page(s) : p. 362-368 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Automobiles represent a large and important investment, and luxury appointments of which leather is by far the best example bestow upon the car interior a degree of comfort and pride of ownership which translates to a strong selling point. Anything which detracts from the luxury experience creates customer dissatisfaction. Part I of this series outlined the problem of interior noise that originates from the friction of two leather surfaces rubbing against each other and demonstrated that the origin of the noise is energy dissipation manifesting itself as an annoying squeak. A way to test for noise was explained, and a comprehensive leather finish solution was described. This paper examines the issue of solar radiative heating of dark leather surfaces, reviews the applicable physical basis, and makes available a cost-effective solution, in this case a remarkably simple one, to the leather finisher.
