Titre : The effect of conservation defects on the Suede quality of double-face Type de document : texte imprimé Auteurs : Behzat Oral Bitlisli, Auteur ; Meral Birbir, Auteur ; I. Yasa, Auteur ; O. Sari, Auteur ; Bahri Basaran, Auteur ; Huseyin Ata Karavana, Auteur Année de publication : 2004 Article en page(s) : p. 494-501 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this research, the effects of microorganisms on suede quality of double-face leather were examined. The bacterial numbers on salted sheepskin samples were found as 1.8x106-4.3x107 cfu/g on solid medium and 1.9x106-4.7x107 cfu/g on halophile medium containing 10-30% NaCl. However it was found that salted sheepskins contained 4.4x101-2.0x104 cfu/g of fungi. While 53-74% of halophilic bacteria and 39-58% of fungi showed proteolytic activity, 47-62% of halophilic bacteria and 35-54% of fungi showed lipolytic activity. It was observed that defective light stained areas on suede surface of finished double-face leathers were caused by microorganisms on salted sheepskins and that these defects correspond to 35% of the total double-face leathers amount. Consequently, it was decided that the proteolytic and lipolytic activities of microorganisms on the flesh side of the sheepskins decreased the suede quality and caused economical losses.

Titre : Studies on semi-metal tanning Type de document : texte imprimé Auteurs : Anthony D. Covington, Auteur ; Graham Lampard, Auteur Année de publication : 2004 Article en page(s) : p. 502-509 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This paper outlines some ideas on the structural stability of collagen and its hydrothermal stability. It addresses why semi-metal tannages confer high hydrothermal stability to collagen. Myrabolan tanned sheepskin was retanned with vanadium(IV) oxysulphate or basic titanium(III) sulphate, iso-electronic d1 transition metal salts, to produce semi-metal leathers with shrinkage temperatures of 104 and 100°C, respectively. After storing the leathers for a year at ambient conditions, the shrinkage temperature of the semi vanadyl leather had fallen to 60°C, an equivalent shrinkage temperature to that of raw collagen, but the semi titanium leather was essentially unchanged. Possible reasons for this observation are discussed.
