Weyland, Auteur Année de publication : 1995 Article en page(s) : p. 1-12 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Water borne finishes are used nowadays for producting leathers that can meet up to the highest quality and physical requirements. The study deals with effects that can lead to problems in aquepis finishing. Especially, various kinds of grey effects are briefly describes and classified, followed by the attempt to analyze the causes.Some ideas are discussed as to how these problems can be avoided or overcome. The suscespibility of finishes to these effects in relation to changes in the formulation is shown in the results of a trial series.

Preservation of cattle hides with potassium chloride / David G. Bailey in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXX, N° 1 (01/1995)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXX, N° 1 (01/1995) . - p. 13-21 Titre : Preservation of cattle hides with potassium chloride Type de document : texte imprimé Auteurs : David G. Bailey, Auteur Année de publication : 1995 Article en page(s) : p. 13-21 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Research was conducted to evaluate the effectiveness of Potassium chloride(KCl) as an alternative to sodium chloride(NaCl)for the preservation of cattle hides. The incentive for this research is that concentrated KCl solutions do not cause the environmental problems that are associared with satured brine. Excess KCl brine from a curing raceway can be applied directly to the soil as a fertilizer providing potassium, a necessary plant macro nutrient. While KCl is more expensive than salt on a pound for pound basis the savings in brine disposal is some situations will more than make up the difference.On a laboratory scale we have demonstrated that cattle hide samples soaked in concentrated solutions of KCl and drained of excess moisture appeared to be well preserved after six months. A matched side study of KCl cured hides vs. NaCl cured hides was conducted in which the sides were stored for forty days before tanning. No signifiant differences were observed in two different lines of leather manufactured from hides.
