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 کاملDyeing with Disperse Dyes
Before the First World War, almost all dyes were applied from solution in an aqueous dyebath to substrates such as cotton, wool, silk and other natural fibres. However, the introduction of a man-made fibre, cellulose acetate, with its inherent hydrophobic nature, created a situation where very few of the available dyes had affinity for the new fibre. Water-soluble anionic dyes had little substa...
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...
متن کاملSynthesis Of Some Novel Azo Dyes And Their Dyeing, Redox And Antifungal Properties
Azo dyes are widely used colorants in consumer products such as leather, textiles, agriculture, cosmetics and in laboratories as indicators. This paper describes the synthesis of some novel azo dyes starting from 3-nitro salicylic acid. The synthesized dyes were investigated for their redox potentials, evaluated for their dying ability on cotton fabrics, resistivity against the fungi growth on ...
