Titre : Graphene oxide modified dye : Preparation and its application in the gyeing of biomass-derived aldehyde-tanned chrome-free leather Type de document : texte imprimé Auteurs : Song Guo, Auteur ; Wei Ding, Auteur ; Xiaoyan Pang, Auteur ; Zhiwen Ding, Auteur Année de publication : 2023 Article en page(s) : p. 379-385 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Aldéhydes Un aldéhyde est un composé organique, faisant partie de la famille des composés carbonylés, dont l'un des atomes de carbone primaire (relié au plus à 1 atome de carbone) de la chaîne carbonée porte un groupement carbonyle.
L'aldéhyde le plus simple est le formaldéhyde (ou méthanal), aussi appelé formol lorsqu'il est en solution aqueuse.
Un aldéhyde dérive formellement d'un alcool primaire (oxydation) dont le groupement hydroxyde -OH est en bout de chaîne et se forme suite à l'enlèvement de deux atomes H d'où le nom "alcool déshydrogéné" ou aldéhyde.

Tannage synthétiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In this work, a graphene oxide (GO) modified small molecule reactive dye was prepared and further applied in the dyeing of the biomass-derived aldehyde tanning agent (BAT) tanned chromefree leather for clarifying its application properties. The modified dye (GORD) was prepared by introducing Reactive Red180 (RRD180) onto the surface of GO using the dehydration condensation method. GORD was characterized using FTIR spectroscopy, UVVis spectroscopy, and thermogravimetric analysis. The uptake ratios and the color fastness to sunlight of the GORDs were tested. FTIR and amino group consumption tests showed that RRD-180 was successfully grafted onto the GO lamellar structure, and the color rendering feature of the GORD was similar to that of RRD-180. The introduction of GO reduced the initial degradation temperature of GORD in the second stage (from 170ºC to 150ºC), but this did not affect the shrinkage temperature of the dyed leather. The uptake ratios of RRD-180 and GORDs were both higher than 90%, indicating that GO modification did not affect the reactive dye’s uptake by leather. Importantly, the coloring fastness to sunlight of the grain and flesh sides of the dyed leather was improved, indicating that the GORD endowed the dyed leather with a certain UV-shielding performance. This work provides new ideas for promoting the industrial applications of GO and GO-based functional materials in chrome-free leather manufacturing.

VertIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Chloropyrimidine-based reactive dyes are reported as well suited to textile printing; however, nucleophilic aromatic substitution of chloropyrimidines with amino-containing chromophores is slow and often suffers from poor yields. In this study, a novel and simple method was developed for the synthesis of chloropyrimidine-based reactive dye under microwave irradiation. In addition, the dye was also synthesised by conventional heating for comparison, which took both the reaction time and yield into account. The progress of the synthesis reactions concerned were monitored using capillary electrophoresis and the purity of the dye obtained was assessed by thin-layer chromatography. The structure of the synthesised trichloropyrimidine dye was confirmed by Fourier Transform–infrared spectroscopy and elemental analysis. It was found that the reaction rate of the nucleophilic aromatic substitution carried out under microwave irradiation was 4-fold faster than that carried out under conventional heating, although the enhancement in product yield was modest. These results suggest that microwave irradiation is an effective technique for the synthesis of chloropyrimidine-based reactive dyes. The synthesised chloropyrimidine dye was formulated into an ink and applied onto a wool fabric by ink-jet printing. The printed fabrics were steamed at 102°C for 5-25 minutes at 5-minute intervals. Good K/S and rate of dye fixation were obtained, both of which improved with increasing steaming time. The prints obtained exhibited reasonably good light and wash fastness properties.

When it comes to developing waterborne clearcoats, however, common organic light stabilisers are usually very difficult to incorporate effectively and homogeneously because of their hydrophobicity. Microencapsulation of such water-insoluble, hydrophobic additives may show a way forward, making them water compatible.

ViscositéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : New functionalized liquid reactive raw materials have been developed by Shell Chemical to help meet the emerging needs of the adhesive formulator and converter for a 100% solids warm melt technology system capable of producing tapes and labels for high performance applications. These new raw materials can be formulated with conventional compounding ingredients and cationic photoinitiators and are easily crosslinked at a variety of coat weights with UV light. Benchmarking studies have shown that simple starting point KLP adhesive formulations achieved a comparable balance of high performance PSA properties when tested alongside a basket of commercially available acrylic adhesives and transfer tapes. In light of industry trends toward greater use of non-polar plastics, Kraton Liquid Polymer-based adhesives offer potentially significant improvements in both adhesion and cohesive strength when compared to acrylic-based adhesives on surfaces like polyethylene, polypropylene and TPO. The satured nature of these new liquid reactive raw materials provides good overall stability in a variety of challenging environments as determined by a series of accelerated aging studies.These novel raw materials could provide the PSA industry with new liquid reactive polymers that can be formulated to help meet the goal of reducing use of VOCs while achieving higher productivity and high performance.
