Solidité de la couleurIndex. décimale : 667.3 Teinture et impression des tissus Résumé : We report here the synthesis and characterisation of a new medium-reactivity reactive dye containing 2-sulphophenoxy-4-chloro-s-triazine, having enhanced the activity of the chlorine atom for further substitution by the functional groups carried by wool fibre. 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.

solvantsIndex. 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.Note de contenu : - Methodology

Tension superficielleIndex. 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.Note de contenu : - EXPERIMENTAL METHODS : Printing substrates - Surface tention and water contact angle - Surface roughness

RugositéIndex. 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.

Matériaux -- Propriétés fonctionnellesIndex. décimale : 667.4 Encres Résumé : The author provides an overview on classic examples of commercial intelligent inks.
The traditional role of an ink is as a passive communicator of information, such as product and producer names, ingredients, instructions, price, selle-by date and bar code. This role is changing and nowhere is this better demonstrated than in the area of intelligent inks, ie inks that are reactive, responding to the substrate on which they are applied or the environment they find themselves and through their response providing information. The growing interest in such inks is driven largely by the demand of information.Note de contenu : - Fake inks
