Tannage Résumé : An investigation has been carried out on the uptake, penetration into wet blue and the dispersion in the tannery vessel of the fungicide Kathon XB2-ERB. The trial also followed the fate of the chemical through subsequent processing of the wet blue to the dyed crust stage. Kathon XB2-ERB is a microemulsion of the active ingredient 2-n-octyl-4-isothiazolin-3-one. It was found that the fungicide was rapidly taken up by the wet blue, but did not penetrate uniformly into the cross-section. A larger inter hide variation of fungicide concentrations was found, while intra hide variation was small. About 30% of the active ingredient was washed from the treated leather during subsequent processing.

An acoustic emission study of staking and fatliquor / Paul L. Kronick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXVIII, N° 5 (05/1993)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXVIII, N° 5 (05/1993) . - p. 178-186 Titre : An acoustic emission study of staking and fatliquor Type de document : texte imprimé Auteurs : Paul L. Kronick, Auteur ; Angela R. Page, Auteur ; Michael Komanowsky, Auteur Année de publication : 1993 Article en page(s) : p. 178-186 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The chemical treatment leather with fatliquor and physical treatment of staking produce similar esthetic results. The effects of two such different treatments on the structure of the leather, however, and perhaps various other responses to deformation, are expected to be different. The equivalence of fatliquoring and staking were investigated by comparing the effects of the treatments on the stress-strain curves and the acoustic emission observed during tensile testing. It was found that staking affects only the first 25% of the elongation at break, lowering the initial modulus, while fatliquors affect the whole stress-strain curve. The initial part becomes concave upward instead of downward, and the elongation and stress at failure are greater. Acoustic emission from leather that was merely staked was suppressed only at small elongations, while it was smaller at all elongations from leather that had fatliquor. The results are shown to be consistent with a domain model of deformation. A nondestructive determination of the elongation of leather at tensile failure, based on acoustic emission, is derived from the observations.
