The challenge of european automotive uphostery finishes / F. S. Policki in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 74, N° 4 (07-08/1990)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 74, N° 4 (07-08/1990) . - p. 99-103 Titre : The challenge of european automotive uphostery finishes Type de document : texte imprimé Auteurs : F. S. Policki, Auteur Année de publication : 1990 Article en page(s) : p. 99-103 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : From the general topic of surface coating developments I have chosen to discuss automotive uphostery finishing for several reasons : 1. It represents state of the art finishing with regard to physical performance, 2. It is a growth area for european tanners, 3. It is one short step away from aircraft upholstery, which is the potential growth area for the future.

TCMTB binding and antifungal activity in wet-blue leather / W. M. Fowler in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 74, N° 4 (07-08/1990)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 74, N° 4 (07-08/1990) . - p. 107-115 Titre : TCMTB binding and antifungal activity in wet-blue leather Type de document : texte imprimé Auteurs : W. M. Fowler, Auteur ; Alan E. Russell, Auteur Année de publication : 1990 Article en page(s) : p. 107-115 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The uptake and antifungal activity of 2-(thiocyanomethylthio) benzothiazole (TCMTB) active ingredient from emulsion dispersions ob Busan 30L on chrome-tanned wet-blue leather has been investigated at treatment temperatures of 10°, 25°, 40° and 55°C. At lower fungicide treatment concentrations, binding tended to follow a typical mass-action type binding isotherm, increasing slightly with temperature up to 40°C. At higher float concentrations, an inflexion point was apparent beyond which uptakes showed marked increase with concentration. This inflexion point signifying a change in binding characteristics, occurred at progressively lower concentrations with increasing temperature. Antifungal activity in terms of storage periods ton onset of fungal growth was determined on the wet-blue cuttings immetiately after treatment and drainage and also on sample discs after exhaustive extraction of free TCMTB using dichloromethane. Storage performance testing of the various treated wet-blue leathers was carried out by three methods, namely moist incubation at 22°C with re-inoculation, potato dextrose agar embedding with incubation at 22°C and humidity chamber exposure testing at 30°C. Residual protective periods showed a curvilinear increase with dosage offer and surface uptake of TCMTB. In the low dosage range up to 0.1 % fungicide offer, treatment temperature had only a relatively slight effect in promoting TCMTB uptake and improving storage protection. At higher dosages, the influence of temperature on uptake and storage protection was greater due to the increase in surface deposition of TCMTB at the elevated temperatures. Only a proportion of the TCMTB uptake was recovered by direct solvent extraction of the treated wet-blue. At higher treatment concentrations and temperatures, which have a destabilising effect on float emulsions, residual recoveries of TCMTB by solvent extraction remained relatively high, consistent with more ready removal of superficially deposited TCMTB from the leather surfaces by the solvent. Solvent extraction of the treated wet-blue reduced storage margins, but in terms of the moist storage test, storage response in relation to TCMTB content was comparable after extraction, indicating that both bound an interstitial TCMTB in the leather offered effective protection. Comparison of the various storage performance tests indicated that dosage-storage response was poorer under conditions of continuous fungal exposure in the humidity chamber and potato dextroses agar tests compared with moist incubation, especially after surface extract of TCMTB. Results of the study provide a further insight into the mode of interaction of TCMTB emulsion dispersion with wet-blue leather, the importance of emulsion stability in practical application and the role of bound and unbound fungicide in antifungal activity.

The heteregeneous interaction between sulpho-syntans and collagen. Part V. polyelectrolyte complex type / Z. Vinklàrek in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 74, N° 4 (07-08/1990)

Part V. polyelectrolyte complex type Type de document : texte imprimé Auteurs : Z. Vinklàrek, Auteur ; M. Vondruska, Auteur ; J. Kupec, Auteur Année de publication : 1990 Article en page(s) : p. 116-121 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The stoichiometry of the above reaction has been studied with regard to its dependence on reaction conditions. An effective equivalent weight for collagen has been determined based on this study. BY comparison of the determined effective equivalent weight with the calculated value the type of local Coulomb's interactions and also the type of the polyelectrolyte complex formed have been predicted. The results support the fact that the polyelectrolyte complex formation of the pendent-pendent type occurs. This has been substantially confirmed by elemental analysis.
