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...

Madder is considered the queen of the reds which is one of the oldest used natural dyes. In this study, madder was applied to cotton and silk fabrics by using mordants in various ways to investigate the coloring effects. Alum and copper sulphate were used as mordants not only before and after dyeing process but also during the process. The aqueous extract of the dye was applied on the scoured c...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

Abstract A chemical modification of cotton fabrics by 2-diethylaminoethyl chloride (DEAE-Cl) was achieved, and the resulted demonstrated salt-free dyeing properties with anionic dyes. Nucleophilic property hydroxyl groups in cellulose enhanced under alkaline conditions could react DEAE-Cl, a possessing both nucleophilic electrophilic sites. The monolayered DEAE-grafted further DEAE-Cl to form m...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

Abstract In this paper, polypyrrole coated conductive fabrics were prepared using pyrrole as the monomer, p-toluene sulfonic acid doping agent and ammonium persulfate oxidant, adopting simple method of situ polymerization liquid phase. Six types polyester-cotton blended fabrics, nylon wool silk basalt aramid fabric respectively base materials same process conditions; its electrical conductivity...

Fruit peels are a rich source of many substances, such as pectin. Extraction natural thickening agent (pectin) from fruit waste (orange and pomegranate peels) is an environmentally friendly alternative to commercial thickeners cheap for use in the printing synthetic fabrics, especially polyester polyacrylic fabrics. Hexamine was used treat extracted pectin make it appropriate alkali medium cott...

Digital image processing has been applied to diverse industry disciplines. The wide application of digital image processing can be attributed to the following advantages: accuracy, objectivity, fastness, consistency, and the mixture of them. Although the RUst Defect Assessment(RUDA) method [1] was efficiently used to differentiate defective images from non-defective images on blue color coat, i...

Abstract For conjugating sulfa drug moieties with Schiff’s bases scaffold in the same build through an azo linker to take advantage of bioactive feature both motifs, we designed and synthesized a series disperse dyes. The target dyes, methyl 2-( E -2-hydroxy-5-(( )-(4-sulfa-derivative) diazenyl)benzylidene) hydrazine-1-carbodithioates 4a – e have been via acidic reaction dyes 3a hydrazine carbo...
