[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXI (Année 1986) . - p. 62-68 Titre : A method of bleaching collagenous materials Type de document : texte imprimé Auteurs : D. E. Peters, Auteur ; U. Adminis, Auteur Année de publication : 1986 Article en page(s) : p. 62-68 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Methods used previously for the production of sutures, sports racket or musicacal instrument strings involve bleaching with a variety of materials which commonly include peroxides. These bleaches are often ineffecive and leave the product a pale yellow to brown colour. A new method of bleaching which uses chlorine dioxide is described. This method is effective with products made from intestine but may be less successful with those prepared from hide. Instrumental assessment of the colour of these products is found to be unsatisfactory in comparison with visual assessment.

The need for improved fungicides for wet-blue / U. Adminis in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 86, N° 3 (05-06/2002)

Adminis, Auteur ; C. Huynh, Auteur ; Catherine A. Money, Auteur Année de publication : 2002 Article en page(s) : p. 118-121 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Etudes comparatives Fongicides Tests d'efficacité Wet-blue (tannage) Peau tannée au chrome (le chrome donne une couleur bleue) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Mould protection of wet-blue continues to be a major cost and concern to tanners. There is a need for more effective fungicides with low human and fish toxicity and minimum environmental impact. The advantages and disadvantages of currently used fungicides are reviewed. There are problems associated with reduced effectiveness of some fungicides in the presence of sulfide, bisulfite, oxidising agents or grease. Systems used to overcome these problems are compared. Also, fungicides which can control difficult moulds, such as Cladosporium, are discussed. Standard methods for testing fungicidal efficacy are compared with tropical chamber methods. Results of both laboratory and industrial trials comparing a range of fungicides show the benefits of some combinations.
