Rayonnement infrarougeIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Counterfeit leather products infringe the intellectual property rights of the business, cause enormous economic loss, and negatively influence the business enthusiasm for innovation. However, traditional anti-counterfeiting materials for leather products suffer from complicated fabrication procedures, photobleaching, and high volatile organic compound (VOC) emissions. Here, a sustainable and invisible anti-counterfeiting ink composed of waterborne polyurethane and water-dispersible lanthanide-doped upconversion nanoparticles (UCNPs) featuring ease of preparation, high photostability, non-toxicity, low VOC emissions, and strong adhesion strength for leather products is designed and synthesized. After decorating on the surface of leather products, the obtained patterns are invisible under normal light conditions. Upon irradiation at 808 nm, the invisible patterns can be observed by naked eyes due to the visible light emitted by 808 nm excited UCNPs. Our approach described here opens a new pathway to realize the long-term, stable anti-counterfeiting function of leather products.

Substances dangereuses -- Suppression ou remplacementIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Throughout history, leather has played a leading role as the material of choice for equipment, protective clothing and popular fashion. From cowboy boots and hats to pilot jackets and caps to rock star trousers and armbands, leather continues to be one of the most significant and fashionable materials of all time. The author provides an update on the latest legislation affecting restricted substances in leather chemicals. Note de contenu : - Preserving the natural properties of animal skin
- Steps in leather processing associated with restricted substances : Soaking - Pickling - Tanning - Retanning - Dyeing - Fatliquoring - stain repellent finishing - Finishing

RevêtementsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Copper nanoparticles were synthesized using myrobalan (tannin) extract as a reducing agent. The synthesized nanoparticles were used in the coating of leather after the finishing process of upper leather to enhance the antimicrobial properties of leather. Primarily, the synthesized myrobalan copper nanoparticles (M-CuNPs) were characterized using UV-Spectroscopy (UV), which resulted in an absorption peak at 412 nm, confirming the presence of CuNPs in the solution. The size distribution and zeta potential values of M-CuNPs were analyzed by Dynamic Light Scattering (DLS) which resulted in an average particle size of 104 nm and zeta potential value of -28mv. These values affirm the stability of the M-CuNPs. Scanning Electron Microscope (SEM) image showed that the particles are spherical in shape. The elemental composition of M-CuNPs was confirmed using Energy dispersive X-ray (EDX) studies. Fourier transform infrared (FTIR) spectra showed peaks at 3173 cm-1, 1727 cm-1, 1147 cm-1, and 624 cm-1, which correspond to -OH, C=O, C-O, and C-H respectively confirming functional groups involved in the synthesis and capping process. The antibacterial activity of the M-CuNPs coated finished leather was evaluated against Grampositive (Bacillus subtilis) and Gram-negative (Serratia marcescens) bacteria, which are common pathogenic species that effect the preservation capabilities of the leather. The M-CuNPs coated finished leather exhibits strong antimicrobial activity against both Gram-positive (Bacillus subtilis) and Gram-negative (Serratia marcescens) bacteria. Hence from the above study, M-CuNPs can be used as a sustainable antibacterial agent for preserving leather and its products.
