Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather quality depends largely on the physical, mechanical and organoleptic characteristics of the finished leather from which the final articles are manufactured. Tearing strength and ball burst tests are especially relevant for leather goods that will be subjected to significant tearing and bursting stresses during use.
The influence of different fatliquors on tearing and ball burst tests is studied using wet-blue leathers from Ireland as starting material. Leathers were retanned and dyed following a conventional process and then, they were fatliquored with nine different fatliquoring agents provided by Trumpler Española. A 7% of active matter (on shaved weight) was applied. After a final washing, a sample of the treated leathers was kept in "crust" state (without finishing), and the rest received a light finishing process following a conventional recipe.
To estimate differences between sides, the central parts of them were fatliquored with the same combination used as reference (sulphited triglycerides of rapeseed oil/fatty polymer). The characteristic components of the fatliquoring agents used were a) Soy lecithin, b) Sulphited triglycerides of rapeseed oil, c) Acrylic polymer (waterproofing agent), d) Fatty Polymers (sarcosinates), e) Sulphated triglycerides of rapeseed oil, f) Phosphoric Ester, g) C14 Paraffin, h) Sulphonated paraffin, and i) Sulphited fish oil.
Based on the experimental results, treatments with similar effects on tearing and ball burst test behavior were grouped, clustering the fatliquors with similar effects on these characteristics when compared with the results of the non-fatliquored leather. The effect of finishing has also been studied.Note de contenu : - Crack increase in tearing and energy

This comfort is related to the capacity of absorption and desorption of moisture and with the physical, mechanical and organoleptic characteristics of the leather. After tanning, fatliquoring and retanning are the operations that more intensively modify the characteristics of leather articles.
This work is a continuation of two previous ones that have studied the influence of fatliquoring on softness and compressibility of leather and on grain and corium quality of leather assessed by ball bursting and tearing tests. In this case, the effect of fatliquoring on moisture absorption-desorption characteristics of leather is studied. The experimental work has been carried out in the pilot plant of Trumpler Española S. A. and the moisture absorption-desorption tests in the Laboratory of Thermal Analysis and Calorimetry of the IQAC. The behavior of non-fatliquored leather and that of leather fatliquored with a combination of sulphited triglycerides of colza oil and fatty polymer (TCSi/PGR) or fatliquored separately with their components TCSi and PGR, or with phosphoric ester ESF or sulphited fish oil Psi has been determined.
The determination of the size of the moisture absorbing monolayer (Xm), the binding energy constants of the monolayer C and the multilayer K, the maximum absorption capacity at saturation X1 and the hysteresis (Hyst.) between absorption and desorption, enabled us to classify the different fatliquoring agents according to stage (crust-blue, finished-red) by applying factorial analysis (see following graph). Finishing is the factor that best explains this behavior. Finishing decreases the size of the monolayer and increases the binding energy constants. Fatliquoring decreases the maximum absorption capacity and hysteresis, partially affecting the reduction of the monolayer size.Note de contenu : - INTRODUCTION : Absorption isotherms - Objective

Titre : Elasticity and setting of stretched leather Type de document : texte imprimé Auteurs : Albert M. Manich, Auteur ; M. de Castellar, Auteur ; B. Gonzà lez, Auteur ; M. Ussman, Auteur ; Agusti Marsal, Auteur Année de publication : 2007 Article en page(s) : p. 43-51 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The effect of stretching treatments on the balance between plasticity and elasticity of leather has been studied. Four different tanned and fatliquored bovine leathers were subjected to stretching treatments completely immersed in water. Variables of stretching were a) water temperatures between 60 and 80ºC, b) stretching ratios between 1.20 and 1.40 and c) stretching time between 10 and 20 min. Thickness and apparent density were measured. Variations in plasticity-elasticity balance induced by the stretching treatments were assessed subjecting the samples at two cycle loading-unloading test measuring the elongation induced by the maximum load in the first cycle, the Immediate Elastic Recovery, Delayed Recovery, Permanent Set and the Bedding-in Work Factor. Stretching favours the bedding-in and setting of the network of collagen fibres, increases the elasticity and decreases the plasticity of leather. When subjected to cyclic loading, straining induces additional bedding-in effect on the network of collagen fibres. Leather straining and their immediate elastic recovery and permanent set mainly depend on the applied load while delayed recovery and bedding-in is more dependent on the leather structure than on the load applied.

Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The influence of different factors on the waterproofing capacity of retanning-fatliquoring polymers was studied in an earlier work. In the present paper, given that the production of waterproofed leather articles requiresthe use of different retanning agents, the effect of these agents on water-repellency is evaluated. The variation of water repellency with time is also studied. It has been confirmed that the retanning agent plays an important role in the final degree of water repellency. Different retanning agents yielded varying water repellency rates. Time increased the waterproofing properties of the leather. However, the water-repellency values became uniform after subjecting the leather to a temperature of 80 °C in an oven for 48 hours.

Part I Type de document : texte imprimé Auteurs : Ramón Palop, Auteur ; Agusti Marsal, Auteur Année de publication : 2004 Article en page(s) : p. 409-415 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the last decades several products have been applied to confer waterproofing properties to the leather: natural oils, alkenyl succinic acids, polysiloxanes, chromium soaps (stearates and oleates), phosphoric esters alone or in combination with alkenyl succinic acids and reactive agents or amphiphilic polymers. Other products (silicone derivative, fluorcarbonated resin) confer not only waterproofing but also oil repellent properties to the leather. In this work, the waterproofing behaviour of retanning-fatliquoring polymers alone or in combination with other hydrophobic products such as a silicone derivative and a fluorcarbonated resin is studied. The anionization of the tanned leather on the waterproofing performance of the retanning-fatliquoring polymer and the influence of the addition of fatliquoring auxiliaries to the tanning bath on the water repellent properties of the leather produced are also evaluated. A complete anionization of the tanned leather, by using a naphthalene sulphonic acid salt, is of paramount importance to obtain good water repellency. The addition of a sulphochlorinated paraffin and a phosphoric ester to the tanning bath reduced water-repellency values drastically.
