Sulfur dyed cellulosic goods exhibit limited wash fastness against oxidative laundering; particularly to washing powder formulations containing activated bleaches. This study presents a novel two-bath exhaust finishing process improve the of Black 1 cotton fabrics reduced with two different reducing agents—sodium sulfide and commercial glucose-based Diresul agent D. The involves sequential afte...

Newfangled vinylsulfone (VS) based fiberreactive dyes were synthesized and applied to mill desized, bleached and mercerized textile fabric (100% cotton). Padthermosol dyeing method was utilized due to less hazardous environmental affects and high dye fixation to optimize dyeing quality parameters i.e. salt concentration, pH, dyeing time and dyeing temperature. The pretreated and dyed cotton fab...

Lately, the utilization of natural colorants in textile dyeing and printing has come to forepart manufacturing goods due increased environmental troubles. In this study, wool yarns were dyed with ternary dye combinations (Scutellaria Orientalis L, Rubia Tinctorium and, Punica Granatum L ). The color coordinates washing light fastness investigated. Washing are fair good. Dyed worked calorimetric...

Historic textiles cannot be washed in a washing machine or with commercial detergent. Washing of historic textile conservation is done after considering various factors such as the condition textile, age color fastness dyes, type fiber, and stain. to remove unwanted materials dust, dirt, stains, etc, which may damaging object. Organic surfactants have been used India detergents shampoos for age...

A series of novel monoazo-disperse dyes containing pyrazolo[1,5-a]pyrimidine structures were synthesized starting with the coupling reaction between ethyl cyanoacetate and 4-hydroxybenzenediazonium chloride, followed by treatment of the resulting hydrazone product with hydrazine hydrate. The pyrazolohydrazone 6 is then treated with either 2,4-pentandione and enaminonitrile or aryl-substituted e...

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...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Fabrics dyed using myrobalan extract as natural mordants and green dye. A red color were obtained by using theses mordants. The color of dyed fabrics was investigated in CIELab L, a and b and K/S values. Finally, all dyed fabrics were tested for wash and light fastness properties as per ISO standard t...

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 ...

Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...
