Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In conventional chrome tannages approximately one-third og the chrome tanning material employed remains unused. With the aid of a chrome balance it is shown that this unfixed chrome in the wet leather is important because the greater portion of it reaches the effluent during the processes following the tannage. New chrome tanning processes are described which make it possible to achieve much better utilization of the chrome tanning material employed. The chrome balance of such a modern tannage is compared with that of a conventional tannage where residual liquors are recycled. It is shown that the leather tanned by the new process will release hardly any chrome during subsequent operations. The practical application of modern tannages of this type and the properties obtained with this process are discussed.

The history of chrome tanning materials / Wolfhard Luck in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 70 (Année 1986)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 70 (Année 1986) . - p. 99-103 Titre : The history of chrome tanning materials Type de document : texte imprimé Auteurs : Wolfhard Luck, Auteur Année de publication : 1986 Article en page(s) : p. 99-103 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The article describes the history of ready-for-tanning chroma tanning materials from the time they were first developed to the present day. The first such product was a liquid chrom tanning material which appeared on the American market. This was followed by drum-dried chrome tanning powders, readily soluble spray-dried chrome tanning materials and, later, by self-basifying chrome tanning materials. Recently, special chrome tanning materials from chrome tanning processes with high float exhaustion have been developed. Industrial progress, new production processes for leather and the development of chrome tanning materials have all interacted with each other.
