Titre : The mechanical properties of sheepskin splits as determined by an experimental method Type de document : texte imprimé Auteurs : T. M. van Gulik, Auteur ; P. J. Klopper, Auteur Année de publication : 1987 Article en page(s) : p. 38-42 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Sheepskin flesh splits which had undergone all beamhouse processes were tanned with glutaraldehyde, producing three increasing degrees of tannage according to the resultant elevation of the shrinkage temperature (Ts). The respective specimens were referred to as GA low-grade (Ts60.3+-0.7°C, n=10), GA medium-grade (TS 67.7+-1.2°C, n=15) and GA high-grade (TS 74.8+-0.8°C, n=36).
The thickness, tensile strength and elongation at break of untanned of the specimens were assessed, applying an experimental testing procedure. The thickness of the specimens correlated negatively with the degree of tannage (r=0.78). The tensile strength of the GA high-grade tanned specimens equalled 30.8+-3.6 N/mm2 (n30), corresponding with an increase in tensile strength of approximately 20 %, as compared with the untanned specimens. The tensile strength values of GA low, medium and high grade tanned specimens, did not differ significantly. The elongation at break of the tanned specimens correlated negatively with the degree of tannage (r=-0.68). The stress/strain curves recorded exhibited a sigmoid shape.En ligne : https://drive.google.com/file/d/1ywSwzNYrUv0Di6QuIDswW-cMVFVI7sYP/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9147

Dépôt par pulvérisationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : It may be of interest to you to know that the first mechanically operated spray finishing machine used for finishing leather was invented 46 years ago, in the year 1927. This new machine was designed and developed by A. C. Lawrence Leather Co., in Peabody, Mass. It was described in the patent, which was later issued in July, 1934, as "An Apparatus for Applying Coating Material to Leather or Hides for the Manufacture of Patent Leather." It was the intent of the inventor to use this device to improve the method of applying the varnish finish coats on patent leather. At the time this material was being applied by hand brushing or swabbing, a method which was slow and expensive.
The original machine was semiautomatic in operation and was arranged so that the spray gun carriage could travel continuously up and down in a vertical transverse motion. The leather to he sprayed was supported by rope toggles in a wooden frame which was suspended from an overhead monorail conveyor track. The frame was advanced horizontally by a motorized conveyor chain with an intermittent indexing movement and it remained stationary for each stroke of the spray gun carriage.En ligne : https://drive.google.com/file/d/1ByRzmF-hDafSnj5PyT5Gx7IX2C3s39G_/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38784

LaineIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In investigating the efficiencies of unhairing agents it is necessary to ascertain the effects on the old club hairs, the short undergrowth of young hairs, the follicles and the malpighian layer. These structures and the interfibrillary matter, which consists of albumins, globulins and mucoids, are affected by the times which elapse between the death of the animal, flaying and curing as well as by the methods of curing, and soaking.
The methods of Ioosening the hair by liquid air, warm water, bacteria, enzymes, alkaIine solutions, alkaline solutions with reducing or oxidising agents, acids and lyotropic salts arc discussed and compared with the methods of tightening the hair with bactéricides, moderato concentrations of caustic soda, acid solutions such as pickles or bran drenches, protein precipitants and increasing or decreasing the moisture content in the case of the woolskins.
Microscopie observations show that the unhairing agents all act on the malpighian or soft inner mucous layer. The crux of the unhairing problem is therefore to weaken or partially dissolve the mucous layer of the epidermis and to find a machine which will remove the longer hair and the undergrowth of short young hairs. The soft inner mucous layer is rich in mucoid material. It is still considered that unhairing and bating are in essence the partial removal of this material.
In the application of modern scientific researches to the practice of leather manufacture it must be realised that science is dynamic and not static. In any particular field, the scientist has established certain facts and is investigating a number of possibilities. We must be careful to confine our thoughts to the application of established facts and remember the conditions of time, temperature, concentration, movement and degree of aeration which are inherent in these facts. Conclusions for fresh skins do net necessarily apply to salted ones. Again, precision must be used in visualising the processus of leather manufacture. This is by no means as easy as it might appear to die uninitiated for the smallest details are often significant.Note de contenu : THE STRUCTURE AND GROWTH OF THE HAIR AND EPIDERMIS

Peaux brutesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Crocodile leather with its unique pattern and scarcity is regarded as a leader in the high-grade leather products industry. In order to further improve the quality of crocodile leather products, based on the Crocodylus niloticus raw hides, the trichrome-udan IV staining method, aldehyde fuchshin staining method, scanning electron microscope and polarising microscope were used to study the histology characteristics and fibre weaving of the raw hides, which provides a theoretical basis for formulating tanning scientifically and reasonably.
