The purpose of this study was to investigate the effect of the reactive dye structure and type of penetrant in ink formulation on paper ink-jet printing. Different type of papers, which have same grammage was printed upon with three commercial reactive dyes, CI Reactive Blue 49 Ink 1, 4, CI Reactive Blue 21 Ink 2, Ink 5 and CI Reactive Blue 19 Ink 3, Ink 6, which are based on different reactive group, chromophore and possess different numbers of anionic groups. Ethylene glycol mono butyl ether Ink1 to Ink 3 and Ethylene glycol di-butyl ether Ink 4 to Ink6 were used in ink formulation as penetrants. Optical density, colorimetric properties, wash and light fastness of the printed paper were evaluated at neutral pH. The results indicated that, the printed subjects with Ink 1 to Ink 3 had less optical density, high dye penetration and good wash fastness properties compare to Ink 4 to Ink 6. Ink 2 and Ink 5 are demonstrating excellent to washing and light fastness on the most of the substrates compare to other inks. The light fastness of other inks fixed to paper was poor.

Cotton fabric was treated with fluorine gas in a nitrogen atmosphere. The effect of fluorination treatments on wettability, whiteness index, dyeability and mechanical properties of cotton fabrics were assessed. Kawabata analysis shows that fluorination treatment increases shear stiffness G, shear hysteresis 2HG5, bending stiffness B and overall fabric stiffness Koshi on cotton fabric. Fluorination increases hydrophilicity of cotton by reducing the wetting time to less than 10 seconds for fluorinated cotton. In addition, the uniformity of wetting improves for the fluorinated samples. Fluorinated cotton dyed with two different direct dyes shows a slightly decreased exhaustion rate and colour yield. X-ray Photoelectron Spectroscopy XPS was used to characterize untreated and fluorinated cotton. XPS indicates that oxidation, fluorination and formation bonds - COO and –CHF at 289.5eV occurred on the fluorinated cotton surface.

The dyeing behaviour of annually renewable soybean protein fibres with Madder, Weld and Walnut seed husk, natural dyes, were investigated and their possible antimicrobial effects were evaluated. The results obtained from the dyeing of the Madder on the soybean fabric were compared with those on a wool fabric. It was shown that the amount of the amino acid content of the fibre has a great effect on the final colour depth. The unusual change in the colour of the Madder on the soybean fabric upon washing in an alkaline washing solution is also addressed. Also, a good antimicrobial activity against the gram-positive bacterium for the Walnut husk and Madder dyes were revealed while the effect of Weld dye was practically negligible. However, these natural dyes on the soybean fabric did not show any significant antibacterial properties against gram-negative bacterium.

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for decolorization of Acid Red 88 AR88. It was found that SPEC is capable of decolorizing AR88 entirely after 35minutes by using Ni-TiO2 as a catalyst with higher efficiency than SPE and SE techniques. The results are also shown that SPE had more yield than SE because in the case of SPE, the process was performed not only by sonolysis but also by photoelectrolysis. Furthermore, initial concentration of dye, initial pH, current density and concentration of supporting electrolyte were investigated and the optimum conditions were obtained. Based on the obtained results, SPEC is an appropriate technology for decolorizing

Rosin has a comprehensive application in adhesives, printing inks, protective coatings, rubbers and pharmaceutical. In this work, novel dual UV/thermal curable epoxy rosinate was synthesized by esterification reaction between epoxy resin and purified rosin. This product was evaluated by FT-IR spectroscopy techniques and acid number. UV curable resin was formulated for UV curing ability by benzophenone as photoinitiator, dimethyl-p-toluidine DMPT catalyst, trimethylolpropane triacrylate TMPTA and hydroxylethyl methacrylate HEMA as reactive diluents. Ingredients in formulation of UV/thermal curable epoxy rosinate have been balanced for achieving best properties. The film properties such as TGA and DSC characterization of cured film, hardness, impact and adhesion, gloss, flexibility, solvent rub resistance and gel fraction have been evaluated after UV/ Thermal dual curing.

In the present work an evaluation was carried out on the effect dye-bath pH and mordant type on the obtained shades and fastness properties in wool dyeing with cochineal. In this way wool samples were first mordanted with four different mordants and subsequently dyed with cochineal at different levels of dye-bath pH. Colorimetric evaluations were carried out and fastness properties of the dyed samples were assessed. Changes in chemical structure of the dye in different pH conditions was also discussed. It was found that the pH of dye-bath has a great effect on obtained shades. Based on the results, combination of dyeing in different levels of dye-bath pH along with mordanting with various mordants can considerably develop the range of obtainable hues in dyeing of wool with cochineal. The fastness properties of the dyed samples in different conditions were also studied.
