Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Antimicrobial agents have been used in leather manufacturing to prevent leather products from microbial contamination. In this work, the antifungal activity of green solvent such as propylene carbonate was investigated against the mixed culture of fungi isolated from wet-blue using broth dilution/well diffusion. A concentration of 5% and above (propylene carbonate) showed effective antifungal activity against the mixed culture of fungi and the efficiency of propylene carbonate on the mixed culture increased with increasing concentration/volume. Propylene carbonate exhibited fungistatic activity against the mixed culture of fungi but it lost its activity after a certain period and fungal growth was observed again. It was also found that 2% propylene carbonate in chrome tanning process effectively inhibited the fungal growth and the wet-blue can be preserved up to 30 days without any fungal attack.

This paper deals with the extraction procedure, dyeing behaviour, antifungal activity, and ultraviolet protection of Pterocarya fraxinifolia as a new natural source of dyes. Juglone was found as the main extracted compound after characterisation by ultraviolet-visible spectrophotometry and Fourier transform infrared spectroscopy. Mordanting and subsequent dyeing of wool with extracted juglone were then performed to study the dyeability and antifungal activities. Three metal salts, aluminium sulfate, copper sulfate, and iron sulfate, were used as chelating materials. The colorimetric properties of samples were evaluated using a reflectance spectrophotometer. Furthermore, the washing and light fastness properties were tested according to ISO 105-CO3:1989 and ISO 105-B01:2014. Interestingly, we found P. fraxinifolia to be a source of strong antifungal compounds against microorganisms. Extracted juglone also exhibited strong protection activity against solar ultraviolet rays. Note de contenu : - Ultraviolet absorption by extracted juglone

Caractérisation
CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

Textiles et tissus auto-nettoyantsIndex. décimale : 667.9 Revêtements et enduits Résumé : A fluorine-free superhydrophobic cotton fabric based on nickel stearate with multifunctional properties has been fabricated by a two step simple solution process. The cotton fabric (aNS-CF) exhibits static water contact angle, ~ 160°, and water shedding angle, < 10°, due to in-situ formation of hierarchical (micro and nano) broccoli-like structures of nickel stearate. The superhydrophobic cotton fabric, having superoleophilic property, has been used for separation of a series of light/heavy oil–water mixtures, and ~ 99% separation efficiency has been achieved after 10 cycles of separation process and it has been found to be slightly reduced to ~ 98% after 50 cycles. Antifouling and self-cleaning performance of the fabric has been evaluated effectively using solid and liquid contaminants as well as some common food liquids. The coating exhibits significant mechanical and chemical robustness and laundering durability in harsh conditions. The coated fabric possesses antibacterial (gram-negative E. coli and gram-positive S. aureus) and antifungal (C. albicans) properties leading to ~ 99.99% reduction in microbial growth, which has been remarkably sustained after 50 cycles of washing, abrasion and separation of oil–water mixtures. The stable multifunctional properties of the fabric exhibits a great potential towards a huge domain of practical implementations in smart textiles.

Système de libération contrôlée (technologie)Index. décimale : 667.9 Revêtements et enduits Résumé : The colonization of microorganisms on painted surfaces varies according to paint formulation, support substrate, and environmental conditions. Developing antimicrobial coatings to prevent growth of microorganisms can prevent adverse health and environmental consequences. Release of antimicrobial agents from the coating surface over time presents toxicity and diminishing antimicrobial protection challenges. Herein, we have formulated and performed 272 tests (including the control experiments, and not including the replication assays) on water-based paint formulations against different species, including Aureobasidium pullulans and Chlorella vulgaris, among others, before and after accelerated weathering tests. Based on the zone of inhibition values (Z value) from fungi and algae resistance tests, 97% of the formulations were effective against fungi species prior to accelerated weathering, while approximately one-third were effective against algae species. Formulations with lower Z values (X2-678, X3-P20T, R1-663, and X2-663) indicated slow release of the biocide via diffusion-controlled behavior is effective in performance optimization and minimizing environmental impacts. For antialgae applications, R1-663 and X2-663 with average Z value variations of 3.3 and 2.0 mm, respectively, ensure full protection. Weathering testing demonstrated 3 of 10 samples failed by cracking and delamination. The main objective of this work is to evaluate, compare, and enhance antimicrobial paint formulations considering the advantages of slow-release and controlled-release approaches. Among samples that passed weathering tests, X1-663, X1-P20T, X3-663, and X3-P20T had the most consistent antifungi activity, while X1-663 and X3-663 showed the best antialgae activity. The difference in antifungi and antialgae activity was mainly attributed to differences in release mechanism based on biocides’ solubility in water, size, and diffusion through the coating layer.
