Nettoyage à secIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : There is an increasing tendency to specify the performance of leather. For clothing leather, its behaviour to dry cleaning is an essential property and poor performance is probably the greatest source of consumer complainte. The original UK method for testing leather was based on tumbling with solvent using conditions recommended by Davis and Nursten. Experience with this procedure in the textile industry showed poor correlation with actual dry cleaning and the method was modified by the addition of steel discs. This procedure was subsequently adopted by the textile industry and forms the basis of both ISO and BSI procedures ; it has also been adopted by the SLTC as method SLF 12.5 However, it does not involve detergents and its main drawback so far as leather is concerned is that no re-oiling is involved. This means that the test gives rather worse ratings for leather because removal of oil in the test causes an optical loss of colour which in commercial dry cleaning is restored by addition of oil to a rinse bath or applied as a subsequent spray.
On the Continent, alternative methods have been developed in Germany and Switzerland specifically for leather. The IULTCS Fastness Tests Commission (IEKL) is now considering which of these methods to adopt. Both German and Swiss methods involve detergent addition and some form of oil replacement. In order to provide some factual comparative evidencq, this comparison of methods and some variations in procedure were undertaken so that the IEKL would have a reasonable basis on which to come to a decision. The present position where specifications are based on different methods is clearly unsatisfactory.
Area change after simulated dry cleaning tests has not been incorporated in the SLTC methods, but is referred to in German publications. In this work dimensional changes have been reported on leather conditioned at 20°C, 65 % r.h. initially and after drying. This procedure will tend to maximise recorded shrinkage in tests where solvent is removed at 60°c subject to hysteresis effects.Note de contenu : - EXPERIMENTAL : Grain, change of pattern - Flesh side - Change in pattern - Staining of fabric - Area shrinkage

Titre : Drying your leather without shedding tears Type de document : texte imprimé Auteurs : A. W. Landmann, Auteur Année de publication : 1994 Article en page(s) : p. 44-45 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Drying is the separation of liquid from solid. A number of methods for achieving this are considered not only with efficiency and economy but also taking into consideration the quality of the resultant leather. There are no unique methods which will optimise the results and so each productiondeserves individual analysis to achieve the desired result in the most cost effective way.

Titre : Finishing - art - craft - science Type de document : texte imprimé Auteurs : A. W. Landmann, Auteur Année de publication : 2008 Article en page(s) : p. 250-251 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cuirs et peaux -- Finition Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Art, Craft and Science contribute to the finishing of leather. A new term beautility is introduced to cover the aesthetic properties that finishing gives to leather. A case is made for assigning importance to each of the components of finishing.
For the purpose of this paper, certain leather terms are redefined. Finishing : This includes all processes after preparation e.g. beamhouse and tannage. In the case of parchment and chamois, preparation includes those processes that produce the basic material without coloration Finishing in these terms includes dyeing, fatliquoring and mechanical operations such as sueding, buffing, embossing, tipping, padding, spraying, roller coating, laminating and inkjet printing which are designed to enhance the leather. In this definition, fatliquoring is at the interface and can be regarded as a basic feature of preparation but also part of finishing when used to give the extra softness of gloving or waxy and pull-up finishes. The subject will be discussed in three parts making the case for respectively, Art, Craft and Science. It is left to the reader to decide which of the three contributes most to Finishing.En ligne : https://drive.google.com/file/d/1Vp_ZsgfGrV6SaCIQ26pYo53vQ9bI_8Id/view?usp=share [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38994
