M. Mozersky, Auteur ; Susan K. Iandola, Auteur ; William N. Marmer, Auteur Année de publication : 2001 Article en page(s) : p. 393-397 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Because of the relatively high efficiency with which they produce lean meat, two breeds of cattle which exhibit a high frequency of muscle hypertrophy (mh, commonly referred to as "double muscling"), viz., Piedmontese and Belgian Blue, are being considered for commercial breeding as beef animals. Double muscling results from a genetic deficiency of myostatin, the protein which normally regulates, i.e., limits, muscle growth. Since "double-muscled" animals have a somewhat larger than normal physique, and since the effect of myostatin deficiency is reasonably presumed to include hypertrophy of muscle tissue in the hide, it became important to determine whether the hides of such animals are affected by the condition and would yield leather with unusual, e.g., deficient, physical characteristics. To address this question the physical characteristics of leathers made from the hides of homozygous normal (+/+), homozygous myostatin deficient (mh/mh), and heterozygous (+/mh) cattle were compared to each other. No significant differences between the groups were found, except that leather made from mh/mh cattle had a slightly greater stiffness than leather made from +/+ cattle. Double muscling thus poses no threat of harm (or promise of substantial benefit) to the leather manufacturer which would require monitoring hides from animals endowed with this condition.

Persistence of minority macromolecules of hide through the beamhouse. 2. Removal of collagen type 14 / Paul L. Kronick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. XCII, N° 7 (09/1997)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. XCII, N° 7 (09/1997) . - p. 172-178 Titre : Persistence of minority macromolecules of hide through the beamhouse. 2. Removal of collagen type 14 Type de document : texte imprimé Auteurs : Paul L. Kronick, Auteur ; Susan K. Iandola, Auteur Année de publication : 1997 Article en page(s) : p. 172-178 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Collagen type 14, which is located on the surfaces of collagen fibrils of hide and skin, is a minority collagen that might play a role in leather drying. We show by immunohistological techniques that most of the non-helical portion of collagen type 14 is removed by lime. Unlike collagen type 6, it does not persist in the grain enamel. The triple-helical segments, however, might still persist, since these are not espected to react with the antibody stains used here. How type 14 collagen is removed might be an important feature of hide and grain quality in leather.

Use of an elastomer formed in situ for softening leather / F. Scholnick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXIX, N° 8 (08/1994)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXIX, N° 8 (08/1994) . - p. 260-268 Titre : Use of an elastomer formed in situ for softening leather Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; Paul L. Kronick, Auteur ; Susan K. Iandola, Auteur ; P. H. Cooke, Auteur Année de publication : 1994 Article en page(s) : p. 260-268 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Poly(vinyl oleate) was used as a model compound in a continuing study of polymeric fatliquoring agents. It was emulsion-polymerized in-situ in retanned, non-fatliquored blue stock. The products showed appreciable improvements in mechanical properties, including increased elongation at failure and increased energy to break with no loss in tensile strength. Lower levels of acoustic emission were observed in treated samples, indicating reduction in fiber adhesion. X-ray probe (EDX) microanalysis with the aid of osmium tetroxide was used to locate sites of unsaturation and polymerized vinyl oleate in the interior of the treated leather.
