Nano sized Titanium dioxide (TiO2) produced by sol-gel method was applied on worsted fabrics using mini stenter before and after dyeing with Anthra red B Acid black 194. The effect of TiO2 breaking strength, tear seam slippage, hydrophobicity, fastness color change the examined comparatively considering application step. brightness were measured a spectrophotometer FTIR-ATR, respectively. It ob...

Dyeing of polyester fabrics with thienobenzochromene disperse dyes under conventional and microwave heating conditions was studied in order to determine whether microwave heating could be used to enhance the dyeability of polyester fabrics. Fastness properties of the dyed samples were measured. All samples dyed with or without microwave heating displayed excellent washing and perspiration fastn...

Application of natural dyes in textile coloring has been widely used because it is more environmentally friendly than synthetic and able to produce various colors from one dye. In this study, cotton fabric was treated with chitosan at different concentrations (0, 0.25%, 0.5%, 1%) determine its effect on the color fastness using mango leaves extract as dyes. Fastness ironing, washing sun drying ...

A series of 4-hydroxyphenylazopyrazolopyrimidine disperse dyes were prepared via one-pot reactions of p-hydroxyphenylhydrazone, hydrazine hydrate, and acetylacetone or enaminones using microwave irradiation as an energy source. Structural assignments of the dyes were confirmed by X-ray crystallographic structure determination. Instead of discharging the dyebath after each dyeing cycle, the resi...
