Flame resistance of leather / Kadir Dönmez in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), LXXXVII, N° 1 (01/1992)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > LXXXVII, N° 1 (01/1992) . - p. 1-19 Titre : Flame resistance of leather Type de document : texte imprimé Auteurs : Kadir Dönmez, Auteur ; Waldo E. Kallenberger, Auteur Année de publication : 1992 Article en page(s) : p. 1-19 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Several commercial flame retardants were applied to leather, and then the leathers were tested by ALCA method E50, and by the Oxygen-Index Test Method. Critical factors which would be expected to affect the flame resistance of leather directly were studied also. Various type of fatliquors were examined. The method of application of the flame retardant was tested by dipping the leather in or spraying it with these materials. A broad spectrum of flame retardants was studied so that most theoretical mechanisms of flame resistance would be examined. The numerical results of the flame-resistance tests have been evaluated statistically in order to rank the effectiveness of the various flame retardants and process variations. This study should help to further the objective in leather manufacture of minimizing destruction when exposed to flame.

Ultraviolet-cured coatings without use of acrylates / F. Scholnick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), LXXXVII, N° 1 (01/1992)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > LXXXVII, N° 1 (01/1992) . - p. 20-25 Titre : Ultraviolet-cured coatings without use of acrylates Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; Paul L. Kronick ; B. E. Maleeff, Auteur Année de publication : 1992 Article en page(s) : p. 20-25 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Although leather coatings have been prepared by ultraviolet (UV) irradiation of solvent free, 100% reactive acrylate systems, a process which eliminates air pollution and conserves energy, their industrial adoption has been impeded because of possible toxicity of acrylate chemicals. The coatings described here were prepared from non-acrylic oligomers containing maleate and vinyl functionality, which cure rapidly after exposure to UV light. Odorless coatings were formed with good abrasion resistance. Their flexibility was improved by adjustment of formulation. Other physical properties of these coatings including tensile strength and percent elongation are compared with those obtained from acrylateformulations used as reference.

Protein removal from cattlehides during brine curing I. Identification of bovine serum albumin as the major salt soluble protein component / David G. Bailey in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), LXXXVII, N° 1 (01/1992)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > LXXXVII, N° 1 (01/1992) . - p. 26-35 Titre : Protein removal from cattlehides during brine curing I. Identification of bovine serum albumin as the major salt soluble protein component Type de document : texte imprimé Auteurs : David G. Bailey, Auteur Année de publication : 1992 Article en page(s) : p. 26-35 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Fresh hides delivered within a few hours after slaughter frm a packing house or brine cured hides preserved for many months can serve equally well as raw material for leather manufacture. Although leather with very similar characteristics can be produced from both, they do not respond identically to beamhouse procassing. For example the penetration of chrome into different areas of the hide is more uniform in chrome tanned stock prepared from brine cured hides than from fresh hides. This difference may be due to the removal of proteins from the hide during the brine curing. Removal of extracellular protein may help to open up the hide structure allowing more rapid penetration of chemicals such as chrome during processing. This paper describes the extraction of roteins from cattlehides during brine curing. It demonstrates that the proteins removes from the hide vary qualitatively in different locations within the hide. A single protein, present throughout the hide, appears to continute more than half of the total protein removes during curing. The purification and subsequent identification of that protein as bovine serum albumin (BSA) is reported.
