Fourier, Spectroscopie infrarouge à transformée deIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The historical document studied dates back to the Mamluk period (807-848 AH). It consists of seven pieces and is preserved in the Egyptian National Archives stores. The document suffers from serious damage. Many aspects of deterioration were recorded such as discoloration, warping, stains from different sources, missing parts and gaps. This study aims to document aspects of the deterioration, explain the deterioration mechaism and apply conservation methods.
Non-destructive methods of investigation such as isolation and identification of fungi, shrinkage temperature by using a microscope with a hot table technique and Fourier Transform Infrared Attenuated Total Reflection (FTIR-ATR) were used for damage assessment. The conservation methods used were fixing the ink, disinfection, cleaning, flattening and tensioning, repair of parchment, sewing and preparation for storage. The results of invetigation techniques proved that the deterioration differed in varied parts of the document. The conservation methods improved the appearance andrevealed the aesthetic values of the document.
Historical background : The historical parhcment document studied dates back to the Mamluk period (807-848 AH). It belonged to Khond Tatar(daughter of Eynas El-Yossefy). It is stored in the Egyptian National Archives. It consists of seven differently sized pieces. Both the face and back of each piece are inscribed with carbon ink.Note de contenu : Investigation / Conservation techniques

Titre : Investigations into properties and use of reindeer skin and leather and influence of defects on leather properties Type de document : texte imprimé Auteurs : Taina Korpiharju, Auteur Année de publication : 1994 Article en page(s) : p. 357-363 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The conservation of reindeer skins is a very important process in determining the properties of the resultant leather. Commonly the skins are salted where the reindeer are slaughtered, but,because of the cold climate in artic and subartic zones, the partially frozen skins do not obtain a uniform cure. The frozen areas which are not adequately cured are thus prone to microorganisms, with the result that local skin defects are often generated. These defects can be seen in the skin as translucent patches,especially after the dehairing process in leather production. These defects also have some influence on the properties and use of skin and leather.
This study sets out to investigate the properties of the skin and leather of the semi-domestic reindeer(Rangifer tarandus tarandus). Inherent conditions such as breed, climate, diet, sex and age greatly influence the quality of reindeer skin, as do many kinds of skin defencts.Parasitic infestations in reindeer often cause the leather industry heavy losses.En ligne : https://drive.google.com/file/d/1Rf471yEMoPvtqIpQ5XhGiEYbh1oXFOti/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8042

A water content (dry weight basis) in the range 14-24 percent is acceptable. The time required to reach this level is found to vary tremendously with the prevailing climatic conditions. On a laboratory scale, the influence of temperature on drying rate is investigated, and from the drying rate curves at the different tempera-tures, the "apparent activation energy" of drying is calculated over the range of water contents investigated. The value of this activation energy is of the order of 5-8 Kcals/mole, and does not vary with the water content of the skin down to about ten percent but thereafter shows a marked rise. It is also dependent on the skin thickness. Drying results in a decreased amount of water uptake and an increase in the amount of extractable nitrogen on subsequent soaking, and an increase in the shrinkage temperature of the skin.

Rouvinen, Auteur ; P. Niemelä, Auteur ; M. Marjoniemi, Auteur ; E. Kemppinen, Auteur ; E. Mäntysalo, Auteur Année de publication : 1991 Article en page(s) : p. 122-125 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This study attempts to clarify the effect of straining in the conservation of mink and blue fox skins on their length, contraction in dressing, and their general fur characteristics.
80 blue fox and 88 scan black mink skins were divided into four groups each and submitted to the following experimental treatments before fixing them onto stretching boards and drying : no straining, manual straining (muscle power), straining with a load of 200N and a load of 400N. The skins were measured for their initial fresh length, for dried length, and also for dressed length. The fur characteristics were evaluated in the dried raw skin state after 3 months storage before dressing.
The length of the raw skins increased with increased straining load in minks and blue foxes. Contraction of the skins in the dressing process was also the more pronounced the stronger the strain had been, but all of the skins returned to their initial fresh length. In blue foxes, the fur characteristics were significantly affected by straining. Colour purity, mass and quality class deteriorated when the straining load was raised. In minks, straining did not affect fur quality in the dried raw skin state, but nearly half of the skins strained with the strongest load appeared to be shapeless and pouch-like after dressing.
The fact that pricing at auctions is determined by skin size has brought a temptation to 'create' more length in conservation. This leads, however, to an undesirable deterioration of skin elasticity in dressing, but it should be even and kept with reasonable limits, or the fibre structure of the skins will be permanently damaged.En ligne : https://drive.google.com/file/d/1rQ6AXdLqZCi8ljX47kszRAFa9-0dbo3U/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8686

Titre : Investigations of uniaxial straining of fur in skin state : Part 2 : Effects of straining on physical characteristics in leather state Type de document : texte imprimé Auteurs : M. Marjoniemi, Auteur ; E. Kemppinen, Auteur ; E. Mäntysalo, Auteur ; K. Rouvinen, Auteur ; P. Niemelä, Auteur Année de publication : 1991 Article en page(s) : p. 166-171 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Uniaxial strain of varying magnitude was applied to skins of male and female blue fox (Alopex lagopus) and male scan black mink (Mustela vison) in the conservation process. Effects of the strain along the line of the backbone on physical characteristics, i.e. elongation at break, breaking load, breaking energy and tensile strength were investigated for a number of selected leather samples by using a previously reported special sampling set system. According to the results obtained in this work the mechanical strain has a considerable effect on the physical characteristics of fox leather. The effect is not so clear in the case of strained mink leather.
On the basis of the results obtained in this work it is concluded that fox and mink leather can be strained with a load of 400 N. Even in this case the breaking load remains a high enough value to meet the lower acceptable value for breaking load. Straining with a load of 400 N along the line of the backbone only to some extent homogenizes the tensile and elongation behavior of the leather with respect to the transverse direction.En ligne : https://drive.google.com/file/d/14fB_3UZL0ZPvT_pYI6ZUAU2Rx3nc9DUj/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8690
