Dyeing of Polyester with Disperse Dyes: Part 2. Synthesis and Dyeing Characteristics of Some Azo Disperse Dyes for Polyester Fabrics.
The goal of this study was to utilize carrier for accelerating the rate of dyeing not only to enhance dyeing of polyester fabrics dyed with disperse dyes 3a,b, but also to save energy. Both the color strength expressed as dye uptake and the fastness properties of the dyed fabrics were evaluated.
متن کاملMicrowave assisted dyeing of polyester fabrics with disperse dyes.
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...
متن کاملOne-pot synthesis of disperse dyes under microwave irradiation: dyebath reuse in dyeing of polyester fabrics.
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...
متن کاملSynthesis of Some Novel 2-Amino-5-arylazothiazole Disperse Dyes for Dyeing Polyester Fabrics and Their Antimicrobial Activity.
The present work describes the synthesis of a series of four novel biologically active 2-amino-5-arylazothiazole disperse dyes containing the sulfa drug nucleus. The structures of the synthesized thiazole derivatives are confirmed using UV-spectrophotometry, infrared and nuclear magnetic resonance techniques and elemental analysis. The synthesized dyes are applied to polyester fabrics as disper...
متن کاملNovel Naphthalimide Based Azo Disperse Dyes for Dyeing of Polyester Fabrics
A series of monoazo disperse dyes based on naphthalimide was synthesized using N-alkylcarboxylic acid-1,8-naphthalimide as diazo component and N,N-diethylaniline derivatives as a coupling components. 4-amino-N-ethanoic (propanoic) acid-1,8-naphthalimide was synthesized from 4-nitro-1,8-naphthalic anhydride by imidation and subsequent reduction reactions. These compounds were diazotized and furt...
