Abstract A series of new coloring materials in nanoscale based on 5-(2-aminothiazol-5-yl) thiazol-2-amine and 5-(4-aminophenyl) were synthesized. The pigments prepared using a grinding high˗energy ball-milling technique. X-ray diffraction transmission electron microscopy employed to determine the particle size (40–80 nm). synthesized normal applied printing polyester fabrics. fastness colorimet...

Using Annosol Reactive Blue DS dye as the colorant, an inkjet printing ink was developed, and its rheological properties dynamic surface tension were evaluated for use in dry heat transfer of patterns on bio-based nylon 56 cotton interwoven fabrics. In particular, effects parameters fabrics investigated. The results revealed that optimal custom-produced are follows: hot pressing at 130 °C under...

Abstract Indigo is a natural blue dye produced from the leaves of Indigofera plant, which environmentally friendly and non-carcinogenic. This study aimed to determine reduction potential value molasses brown sugar as reducing agents, examine effect hydrochloric acid concentrations aeration time on amount indigo, test fastness rubbing against solar heat, dry, wet silk fabrics that were dyed by i...

Bacilli from a number of tissues excised from cases of lepromatous and borderline leprosy, unlike mycobacteria, were found to lose their acid-fastness after treatment with pyridine.

A series of new monoazo disperse dyes containing pyrazolopyrimidine moieties was synthesized by coupling malononitrile or 3-aminocrotononitrile with 4-hydroxy- benzenediazonium chloride. Treatment of the resulting products with hydrazine hydrate yields the corresponding 4-arylazoaminopyrazoles, which then react with either 2,4-pentanedione and enaminonitriles or aryl-substituted enaminoketones ...

The polyester (100%), cotton (100%) and Polyester / Cotton blend fabrics (65 / 35; 50 / 50 & 35 / 65) were treated with sodium hydroxide followed by hydrophilic finishing and dyeing to impart hygroscopic and dyeing characteristics. Then the finished fabric was tested for k/s value, fastness properties, wetting behaviour, water retention, wicking behaviour and static charge respectively. The sod...

A series of disperse dyes, 9,10-anthraquinone containing dithiocarbamate, thiourea and triazole fragments, were prepared via consecutive refunctionalization aminoanthraquinones in our previous studies their structures confirmed by the 1H-, 13C-NMR, IR spectra, LC-MS elemental analysis data. The obtained compounds applied on polyester fabrics exhaustion method at 130?C pH 4.0-5.0, dyeing propert...
