[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 15, N° 6 (11/2018) . - p. 1325-1332 Titre : Synthesis of ZnS–Mn nano-luminescent pigment for ink applications Type de document : texte imprimé Année de publication : 2018 Article en page(s) : p. 1325-1332 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Caractérisation Coton Le 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). Encre Lin et constituants Le lin cultivé (Linum usitatissimum) est une plante annuelle de la famille des Linaceae cultivée principalement pour ses fibres, mais aussi pour ses graines oléagineuses. Les fibres du lin permettent de faire des cordes, du tissu (lin textile pour ses qualités anallergiques, isolantes et thermorégulateurs), ou plus récemment des charges isolantes pour des matériaux de construction. Les graines sont utilisées pour produire de l'huile de lin pour l'industrie de l'encre et de la peinture, pour la consommation humaine et animale, à cause de sa richesse en oméga 3. Le lin est une des rares fibres textiles végétales européennes. Elle a comme caractéristiques la légereté, la rigidité et la résistance et comme particularité d'être une fibre longue (plusieurs dizaines de centimètres), par rapport aux fibres courtes (coton, chanvre) ou moyennes (laine). Luminescence Manganèse Nanoparticules Photoluminescence Pigments à effets spéciaux Polyamide 66 Polyvinylpyrrolidone Rhéologie Sérigraphie Sulfure de zinc Textiles et tissus Textiles et tissus imprimés Index. décimale : 667.9 Revêtements et enduits Résumé : In the present study, ZnS–Mn nano-luminescent pigments were synthesized, using co-precipitation method. Polyvinylpyrrolidine (PVP) surface modifier and Mn dopant concentrations were considered as affecting parameters. The luminescent ink was loaded with two different concentrations of pigments. The obtained ink was silk-screened on different types of fabrics mainly treated cotton, cotton and nylon. Structure, microstructure, luminescent properties of nano-pigments, inks and fabrics and also rheological properties of the inks were investigated. The results showed that the ceramic ink prepared with nano-luminescent pigment had high photoluminescence (PL) intensity. Moreover, the optimum concentrations of Mn and PVP for obtaining maximum PL intensity were found as 2 and 5 wt%, respectively. SEM images of fabrics indicated that nanoparticles were loaded, nonuniformly, on the fibers. The treated linen and nylon fabrics showed maximum and minimum PL intensity, respectively, due to ink penetration depth in the fabrics. Furthermore, washing fastness estimated for all fabrics was in the proper range.

In addition, a dichloro-s-triazine dye was also synthesised for the purpose of comparison. The progress of synthesis reactions and purity of the dyes were determined using capillary electrophoresis and thin layer chromatography. The molecular structure and the chemical compositions of the synthesised dyes were confirmed using Fourier Transform–infrared spectral data and elemental analyses. The inks containing the synthesised dyes were formulated and ink-jet-printed onto wool fabrics and then the printed fabrics were steamed at 102°C. Compared with the dichloro-s-triazine dye, superior performance in terms of ink stability, K/S and dye fixation was observed for the new 2-sulphophenoxy-4-chloro-s-triazine dye. In addition, the light fastness of the fabric printed with the inks containing the new dye was 0.5-grade greater than that of the fabric printed with the inks containing the dichloro-s-triazine dye, and no changes in shade and staining were observed following wash fastness tests of the fabrics printed with the inks containing the new dye.

The effect of exposure to inks and solvents on squeegee performance / E. H. Jewell in SURFACE COATINGS INTERNATIONAL. PART B : COATINGS TRANSACTIONS, Vol. 87, B4 (12/2004)  

[article]  inSURFACE COATINGS INTERNATIONAL. PART B : COATINGS TRANSACTIONS > Vol. 87, B4 (12/2004) . - p. 253-260 Titre : The effect of exposure to inks and solvents on squeegee performance Type de document : texte imprimé Auteurs : E. H. Jewell, Auteur ; T. C. Claypole, Auteur ; D. T. Gethin, Auteur Année de publication : 2004 Article en page(s) : p. 253-260 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Absorption Eléments finis, Méthode des Encre Polyuréthanes Racloirs Sérigraphie solvants Index. décimale : 667.9 Revêtements et enduits Résumé : The squeegee in screen printing forces ink into the screen and the screen into contact with the substrate. The squeegee, which is manufactured from polyurethane, has a major influence on screen printing quality. This paper summarises an experimental programme into the durability of squeegees when exposed to inks and solvents. The softer the squeegee the more il was affected by exposure to any ink or solvent with the increases in mass of up to 14%, increases in volume of up to 12%, and reductions in elastic modulus of up to 80%. The low boiling point cleaner and solvent ink had the greatest effect of all the liquids tested. Distortion of the samples during solvent absorption caused small errors in the measurement of the volume and elastic modulus of the samples. The measurement in the increase in mass of the sample provided the most reliable method for estimating any ink/squeegee compatibility problems. Relaxation in the air returned the squeegee to its original mass. No clear relationship could be established between the surface roughness of the sample and the change in squeegee properties. Exposure to ultraviolet (UV) ink increased the mass of the sample with time. Unlike exposure to solvent-based inks, the effect of UV exposure was cumulative with relaxation between exposures doing little to reduce the mass of the squeegee. Relaxation of the squeegee over a two-week period of time under room temperature conditions did little to reduce the mass back to its original level. A printing experiment with an ‘inked’ and new squeegee showed that a two-hour exposure caused a hard squeegee to act like a medium and resulted in a 0.05 increase in printed density. Finite element modelling of a ‘compound’ squeegee showed that the change in modulus had a significant effect on the deformation of the squeegee tip.

Langues : Anglais (eng) Catégories : Angle de contact Encre Héliogravure Masse volumique Polyesters Polypropylène Rugosité Structure biaxiale Tension superficielle Index. décimale : 667.9 Revêtements et enduits Résumé : The effects of some engraving and film substrate parameters on the solid density and dot gain in gravure printing were studied by using polyester, BOPP plain film and BOPP co-extruded film substrates. Bi-axially oriented polypropylene (BOPP) is a product utilised in numerous industries such as food packaging, printing, laminating and labeling. It was concluded that the solid density of print is affected by the roughness values of the film substrates. Increasing the roughness value increases the print density. The number of cells per cm2 and the depth of the cells also affect the solid density. Deeper and fewer cells per cm2 give a lower solid density value than shallower cells and more cells per cm2. Engraving parameters have a major effect on the dot gain. The channel between cells has a positive effect on the dot gain. The cell depth and the number of cells per cm2 also affect the dot gain. The highest dot gain value was measured from the 35% coverage area of all of the scales printed on all the substrates. Also, the highest dot gain values were measured for the prints on polyester the smoothest substrate.

The effects of the interaction of pigment coating with ink on the offset print quality / Sinan Sonmez in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 19, N° 6 (11/2022)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 19, N° 6 (11/2022) . - p. 1851-1858 Titre : The effects of the interaction of pigment coating with ink on the offset print quality Type de document : texte imprimé Auteurs : Sinan Sonmez, Auteur ; Roland Gong, Auteur ; Paul D. Fleming, Auteur ; Qingliu Wu, Auteur Année de publication : 2022 Article en page(s) : p. 1851-1858 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Encre Enrobage (technologie) Formulation (Génie chimique) Huile de soja Offset (imprimerie) Papier et carton couché Revêtements organiques Rugosité Index. décimale : 667.9 Revêtements et enduits Résumé : The study was carried out in order to determine the effect of coating formulations on printing quality. For this purpose, five different coating formulations were created in which kaolin and precipitated calcium carbonate pigments (PCC) were mixed in different proportions. Coating formulations were applied in two layers on a base cardboard. Calendering of the coated base cartons was carried out using a laboratory calender. The prints were made on the calendered cardboards using mineral oil-based, vegetable (soybean) oil-based, and UV inks in a laboratory type offset printing machine. As a result of the study, it was determined that the coating of the base cardboard surface affects the optical and physical properties of the cardboard, the surface properties change according to the amount of pigment used in the formulations, and this change affects the printing quality. In the study, the best printing results in terms of printing quality were obtained with the use of UV ink. Mineral oil-based and vegetable (soybean) oil-based ink were compared in terms of printing quality, and since the values obtained are close to each other, it can be said that vegetable oil-based inks can be preferred instead of mineral oil-based ink, and more environmentally friendly sustainable productions can be realized. It has always provided better results in terms of surface smoothness and printability in coated formulations where the kaolin ratio is increased.
