Specifically, we want to obtain a flame retardant effect using nanostructured coatings that confer thermal stability and fire resistance. The different nanomaterials should be included in a polymeric matrix ; the hybrid organic-inorganic polymers will act as carriers of the nanomaterials, with the ability to interact with the nanoparticles and walls of the nanocapsules. In addition, they must show affinity for the collagen, in order to be introduced in the three-dimensional structure of leather and fixing them on its surface, as well as interacting with the textile substrate. The flame retardant capacity of the two synthesised products has been achieved according to regulations UNE-EN 1021:06 part 1 and 2 and standard UNE 23723 : 1990.

Textiles et tissusIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The main aim of this study is to develop nover rnultifunctional nanotechnology systems that are applied in textile and leather industry processes for the upholstery used on seating for public spaces and vehicles. More specifically, the study seeks to achieve a dirt-free effect using nanostructured coatings that can bath repel dirt and produce a material with self-cleaning properties. To obtain this property, we use polymers for leather finishing polymers and self-assembling technical textile in several nanophases and microphases with a superhydrophobic effect similar to that of the lotus leaf, but with a greater resistance to abrasion. Additionally, in this study we also use hybrid multifunctional polyurethanes, organic-inorganic amphipihilic polymers with hydrophobic, oleophobic, and hydrophilic nanophases and microphases which can spontaneously rearrange on substrates, creating structures that repel both water and dirt.
The study consists of three stages : in i) selecting the most appropriate substances to achieve the self-cleaning effect ; ii) synthesizing nanostructured polymers with elastic properties, hybrid polymers with a fluoropolyurethane base, and the organic part based on self-cross-linking silanes ; iii) assessing the polymers obtained.
To understand the mechanisms of synthesis and action of the nanocomposites, the following characterization techniques have been applied : determination of particle size by means of dynamic light scattering ; determination of contact angle ; and determination of surface roughness.
A total of 25 products were developed. The results indicate that it is possible to produce coatings that give good hydrophobic properties and a self-cleaning effect to leather and textile surfaces. However, when these products are applied as coatings, the appearance and rigidity of the finished leather needs to be further improved.Note de contenu : - Synthesis of nanocomposites to obtain a superhydrophobic surface

QuebrachoLe quebracho est un arbre à écorce ligneuse, mesurant 30 mètres de haut, à feuilles tannées et à fleurs tubulées blanches.
Quebracho est l'un des noms communs, en espagnol, d'au moins trois espèces similaires d'arbres originaires du Gran Chaco, en Amérique latine : Schinopsis lorentzii (quebracho colorado santiagueño), de la famille des Anacardiaceae ; Schinopsis balansae (quebracho colorado chaqueño), de la même famille ;
Aspidosperma quebracho-blanco (quebracho blanc), de la famille des Apocynaceae.
Ces trois espèces sont riches en tanin et fournissent un bois très dur, particulièrement résistant. Leur nom provient de l'espagnol quiebrahacha, qui signifie brise-hache.

Vêtements en cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Dyes based on synthetic formulations are widely used in the leather industry, however, many aryl amine dyes are restricted due to their carcinogenic nature. Environmental concern leads one to look for the dye products based on natural resources, which may have advantages of biodegradability and lower toxicity. We aimed to create an eco-friendly dyeing process by forming in-situ complexes between vegetable tannins and the Cr-Fe tanning salt, where the use of iron salts results in various colours on reaction with various vegetable tannins. Sheepskins were tanned using the Cr-Fe tanning salt and treated with various vegetable tanning materials, brown, black and grey shades were developed. The shades obtained have been quantified by reflectance measurements and compared by visual assessment.
Strength characteristics of the leathers treated with 5% vegetable tannins are higher than those treated with 1% tannins, bulk properties not being affected with the increase in concentration from 1 to 5%. The light, wet and dry rub fastness of the naturally coloured leathers are good with no change on ageing. Colour reproduction at bulk level production is acceptable with minor batch variations.Note de contenu : - EXPERIMENTAL DETAILS : Process details for larger scale trials - Physical testing

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

Vêtements en cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Growing concerns over the toxicity of chromium and its influence on the health of customers using chromium tanned garment leathers has forced the leather industry to search for alternative tanning agents. Semi-metal tanning agents, aldehyde based systems, etc. Semi-metal tanning agents, aldehyde based systems, etc. have been considered but the toxicity issues are lingering. Hence, in the present study an attempt has been made to develop vegetable tannins and subsequent stripping prior to retanning and fatliquoring has been evaluated. It has been found that an 8 % offer of wattle for tanning provides better physical and organoleptic properties. A polyamide based retanning system was found to offer better perspiration and organoleptic properties. Amongst the various fatliquoring compositions, 50:50 combination of synthetic and natural fatliquors was found to offer higher softness. The optimized tanning-retanning-fatliquoring combination was found to be comparable to chrome tanned garment leathers and superior to semichrome garment leathers.

Wet-bright (tannage)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this work we develop a new tanning process (that we call wet-bright) that produces leather free of chromium, aldehydes, aldehyde precursors and organic solvents. Due to the mineral character of the new system, the leather offers a perfect dyeability and high dye affinity, allowing for very bright colors in all leather applications. The leathers offer a perfect dyeability due to the brilliant whiteness of the wet-bright intermediate. This new system consists of the application of Tanfor T™ system (from Kemira) which is safe for both humans and environment and is not classified as hazardous. In addition, when compared to existing traditional processes, there are economic and environmental advantages resulting from the use of this new system. Note de contenu : - TABLES : 1.
