The re-use of salt for the curing of hides Type de document : texte imprimé Auteurs : Desmond R. Cooper, Auteur ; A. C. Galloway, Auteur Année de publication : 1966 Article en page(s) : p. 162-170 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Chlorure de sodium -- Analyse Chlorure de sodium -- Réutilisation Cuirs et peaux -- Analyse Cuirs et peaux -- Conservation Cuirs et peaux -- Propriétés physiques Evaluation Peaux brutes -- Salage Qualité -- Contrôle Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Curing trials with large numbers of hides have shown that the repeated use of salt for preparing wet-salted hides is not to be recommended. As the salt is used over again hide and leather quality and leather strength decrease even when the salt is re-used only four times Note de contenu : - Table 1 : Plan of trial for curing hides with used salt - Table 2 : The shrinkage during curing with used salt - Table 3 : Hide quality assessment after 14 days storage - Table 4 : Hide quality assessment after 103 days storage - Table 5 : Final hide quality assessment just prior to soaking - Table 6 : Hide quality assessment on the lime yard rounding table - Table 7 : Blue sorting of leather produced from the hides curing with used salt - Table 8 : Crusting sorting of leather produced from the hides cured with used salt - Table 9 : Physical properties of leather produced from hides cured with used salt - Table 10 : Salt analysis from each stack - Table 11 : Analysis of hide pieces from each stack En ligne : https://drive.google.com/file/d/1hre6bq7-rHXtGq0m5H5AJcVu8tYEE0gU/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37940 [article]

Determination of bacterial growth rates and their practical significance / Desmond R. Cooper in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 58 (Année 1974)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 58 (Année 1974) . - p. 25-31 Titre : Determination of bacterial growth rates and their practical significance Type de document : texte imprimé Auteurs : Desmond R. Cooper, Auteur ; A. C. Galloway, Auteur ; D. R. Woods, Auteur Année de publication : 1974 Article en page(s) : p. 25-31 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Bactéries -- Croissance Biodégradation Collagène -- Détérioration Cuirs et peaux Peaux brutes Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The growth rates of mixed population of hide bacteria and of pure strains of collagenolytic and non-collagenolytic bacteria have been determinated to show the practical significance of high growth rates in delayed curing and in cured hides. Most of the hide bacteria studied have mean generation times of less than 4 h, which means that under exponential growth rate conditions these bacteria double their number in less than 4 h. This fact and the rate of collagen decomposition by the collagenolytic bacteria can have a significant effect in commercial curing.

Fungicides for treating wet blue hides / A. C. Galloway in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 58 (Année 1974)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 58 (Année 1974) . - p. 67-71 Titre : Fungicides for treating wet blue hides Type de document : texte imprimé Auteurs : A. C. Galloway, Auteur ; Desmond R. Cooper, Auteur Année de publication : 1974 Article en page(s) : p. 67-71 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antifongiques Antimicrobiens Wet-blue (tannage) Peau tannée au chrome (le chrome donne une couleur bleue) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Sodium pentachlorophenate, pentachlorophenol, cresylic acid, beta naphthol and the proprietary products Busan 31, Busan 52, Busan 72, MTC 10 and Preventol have been tested at various concentration levels, added at different stages of processing, for the prevention of natural fungal growth on stored wet blue hides. Sodium pentachlorophenate, pentachlorophenol, cresylic acid and beta naphthol were not very effective in preventing fungal growth for the periods required for overseas delivery of wet blue hides, but could possibly be used at suitable concentrations for the internal short-term holding of wet blue stock in tanneries. The best overall results were obtained with Busan 72 which appeared effective in tannery trials even at concentrations below 0,025% of active ingredient.

Hide and leather characteristics of afrikaner and friesland bulls and steers slaughtered at various ages between birth and 24 months / Alan E. Russell in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 61 et 62 (Années 1977 et 1978)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 61 et 62 (Années 1977 et 1978) . - p. 1-10 Titre : Hide and leather characteristics of afrikaner and friesland bulls and steers slaughtered at various ages between birth and 24 months Type de document : texte imprimé Auteurs : Alan E. Russell, Auteur ; A. C. Galloway, Auteur ; R. L. Boccard, Auteur ; R. T. Naudé, Auteur Année de publication : 1978 Article en page(s) : p. 1-10 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Bovins -- Races Caractérisation Cuirs et peaux -- Analyse Cuirs et peaux -- Propriétés physiques Cuirs et peaux de bovins Mesures de rendement Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Investigation of the influence of breed, sex and age factors on hide and leather characteristics indicates that when young Afrikaner and Friesland bulls and steers are reared under intensive feedlot conditions, bulls have a higher yield of green hide mass than steers and exhibit more favourable leather properties than steers, especially with regard to tensile strength in Friesland bulls. With the onset of sexual maturity in bulls after 12 months of age, accompanying changes in leather physical properties were apparent and tensile strength showed a decline particularly in Friesland bull leathers. These changes in hide physical properties appear to parallel increases in the level of natural crosslinking of the collagen molecular structure during ageing and maturation. Main differences between the two breeds studied were that Afrikaner animals were superior in terms of hide and leather yield whereas the leather of Friesland cattle was qualitatively superior.
