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

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.

Wet-bright (tannage)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Since leather is strongly affected by three main environmental parameters — temperature, relative humidity, and UV radiation — this study focuses on the effect that these three factors have on wet-bright leather ageing. Wet-bright leathers were exposed to weathering affects in a climatic chamber to 1) try and Identity the major variables affecting this weathering process; and 2) check for any possible interactions among these variables. Both a multilevel centralized factorial experimental design and an analysis of variance (ANOVA) were used as statistical tools for estimating the effects of the parameters.

UltrasonsIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Chrome tanning with ultrasound - This work studies the effect of several variables on a series of properties of the final leather obtained from chrome tanning, using ultrasounds as the sole mechanical effect during the tanning operation. The variables studied (at two levels by means of a 2 3 factorial design) are tanning temperature, condition of chrome offered (solid or dissolved) and salt basicity. Our studies indicate that the results obtained measuring parameters such as struck-through time of tanning agent, chromium uptake and its distribution, shrinkage temperature, tensile strength, tear load, grain distension and leather burst distention significantly depend on the previously selected level of one or more of the variables being studied. The study of the evolution of the concentration and basicity of the chromium salts has led us to conclude that reutilization is possible. Results show that ultrasound use in chrome tanning is a possibility to consider in the case of leather goods in which the use of drum may not be avisable.
