Tannage végétalIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : On the finishing Bide in-house GST/Seton tannery we were facing other challenges.
Using only natural binders is limiting the wear properties. We were looking for a sensitive mix of natural binders together with high tech PUs and Acrylics to get the best performances in using as little finish as possible and having as little coverage as possible. The amount applied is about hall of today's automotive semi-aniline.
The result of this development is a smooth yet firm leather article, which has a rich and round body. Natural characteristics such as growth marks or neck wrinkles are a part of this article and get blended in with the finish we use.
Due to very compact lead-in processes and run Urne optimised recipes in production for ECO¬Line leathers, we were able to achieve a further reduction on "high/brand marks" like water and electricity consumption on these leathers.
Corinova, with its characteristics, reminds us of the classic vegetable-tanned ultra luxury vachette leathers that are used for leather goods. Each hide is unique, which is a sign of authenticity and supports the idea of individualisation. The leathers can currently be produced in black and dark brown shades.
In the development of GST/Seton — Corinova, we have created a superior eco-friendly product. The environment matters and leather can be one of the first consumer choices if produced in an eco-friendly manner.En ligne : https://drive.google.com/file/d/1ZyRGpO2JsDpVpEktYqlFPDJZN64ZIQvJ/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=20448

Porosimétrie d'écoulement capillaireIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The unique fibrous arrangement and architectural marvel of collagen in skin matrix are the basis for various physical properties of leather. Air permeability is one of the unique features of skin, which makes the leather matrix superior to synthetic materials. In leather manufacturing finishing process determines the air permeability of the final leather. Therefore, knowledge of the impact of different finishing auxiliaries on the permeability of leather may helpful in selecting an appropriate finishing system for a particular type of leather. In this work, an attempt has been made to analyze the effect of various auxiliaries used in protein, acrylic and polyurethane (PU) based finish coatings on the air permeability of leather. Capillary flow porometer was used to monitor the air permeability (Flow rate cc/sec) at different pressures (psi). The results show that the effect of wax/filler/slip and dye solution on air permeability reduction is low when compared to pigment and binder. In protein and PU finishes, the binder alone and season (combination of all finishing auxiliaries like pigment, binder, and other auxiliaries) has a strong influence on permeability reduction whereas in case of an acrylic based finish, the pigment and binder plays an important role in permeability reduction. Leather coated solely with protein binder shows minimal permeability reduction than compared to leather coated with acrylic or polyurethane binders, whereas in season, acrylic based finishing has a lower permeability profile than that of protein and PU. In that case the permeability profile of protein and PU season coated leathers is almost similar. Note de contenu : - MATERIALS AND METHODS : Permeability measurements - Measurement of film thickness

Traction (mécanique)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Finishing is the process in which a polymeric coating is applied in order to improve the appearance and resistance of leather products. The applications at this stage greatly affect the use and appeal of the final products. In this study, the effect of different coating compositions on the physico-mechanical properties of leather was investigated. For this purpose, three different types of finishing formulations including semi-aniline, lightly pigmented and opaque finishes having different covering powers rated from light to heavy, respectively, were applied to the leathers and results were compared with uncoated counterparts. The findings of the study revealed that the application of lightly pigmented finishing statistically increased the tensile strength, single and double edge tear loads, and stitch tear resistance of the leather to a large extent. Semi-aniline and opaque finishing gave lower or, in some cases, statistically insignificant increases in the physico-mechanical properties of the leathers.

Résistance au rayonnement ultravioletIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Waterborne polyurethane/laponite composites used for leather finishing have been prepared via the solution mixing method. The dispersion stability of laponite and composite emulsions were determined by atomic force microscopy (AFM) and dynamic light scattering (DLS). Thermogravimetric analysis (TGA), tensile testing and UV-Vis spectra were used to test the performance of the resulting films. The results indicate that the nano-particles with negative charges can form highly stable aqueous dispersion under alkaline condition and exhibit good compatibility with anionic waterborne polyurethanes. The emulsions possess good storage stability with an average particle diameter of 80-94nm. The uniformly dispersed clay platelets can markedly improve the thermal stability and mechanical properties of the composites. In addition, the incorporation of small-sized clay is capable of maintaining the transparent appearance of the film and giving an UV-resistant property.
