Fluorescent naphthalimide dyes for polyester fibres
disperse dyes polyester fibres dyeing fluorescent dyes naphthalimide
2009/6/17
Several fluorescent and mostly newly-prepared dyes, derivatives of 4-aminonaphthalimide,
were synthesised. The structures of the dyes prepared were confirmed by 1H NMR
analysis, and their properties...
Synthesis of Bifunctional Monochlorotriazine Reactive Dyes Increasing UV-Protection Properties of Cotton Fabrics
chlorotriazine UV-absorbers ultraviolet protection factor
2009/6/15
Several yellow and red bis-monochlorotriazine reactive dyes with built-in UV-absorber residues were synthesised. Their application properties were determined during the coloration
of cotton, and the ...
Development of Analytical System for Diffusion Profiles of Dyes into Polymer Based on Improved Dual Sorption and Diffusion Mechanism
Dyeing Dual sorption and diffusion Disperse dye Finite difference method
2009/4/29
The validities of the diffusion coefficient calculated by the improved dual diffusion equation and the analytical method proposed in the preceding paper were confirmed by the agreement of the dye dis...
Diffusion Profiles of Dyes into Polymer Based on Dual Sorption and Diffusion Mechanism
Dyeing Diffusion Dual sorption and diffusion Finite difference method
2009/4/29
The diffusion behavior of an acid dye in Nylon 6 has been investigated as a dynamic dye distribution of two thermodynamically distinct populations of Langmuir type adsorption species and Partition ty...
Dyeing Optimization with Metal Complex Acid Dyes for Nylon Fabrics
Nylon fibers pH value Metal complex dyes pH sliding agent
2009/4/21
In general, acid dyes have high affinity toward nylon fibers, meaning that the dyes quickly bind with the polymer. Thus, if the dye is absorbed by the polymer too quickly, the nylon fibers can absor...
Influence of Chemithermomechanical Pulp on the Colour of Pulps Dyed with Direct Dyes
chemical pulp CTMP colour dyeing direct dyes
2009/2/17
The dyeability of chemical pulp and chemithermomechanical pulp (CTMP) and their
mixtures with direct dyes were investigated. It was found that direct dyes were useful
mainly for dyeing paper contain...
Reactive Dyes Derivatives of Quinoline Triazinium Salts for Dyeing Cellulose Fibres in Neutral Medium

2009/2/16
A number of bi-functional fibre-reactive dye derivatives of C.I. Reactive Red 120 containing quinolino-s-triazine groups were synthesised and their application properties during the dyeing of cotton f...
The Comparison of the Kinetics of Hydrolysis of Some Reactive Dyes Before and After Purification
reactive dyes monochloro-s-triazine monofluoro-s-triazine bis (monofluoro-s-triazine) purification
2009/2/11
A dimethylformamide-tetrachloroethylene (DMF/TCE) solvent-nonsolvent mixture was used for the purification of monochloro-s-triazine, monofluoro-s-triazine and bis (monofluoro-s-triazine) reactive dyes...
Reactive Dyes for Single-Bath and Single-Stage Dyeing of Polyester-Cellulose Blends
Reactive dyes 3’-carboxypirydyno-triazine reactive dyes exhaust dyeing of cotton
2009/2/10
Cellulose fibres were dyed with selected dyes containing 3’-carboxypirydyno-triazine reactive systems. The dyeing processes were carried out at a temperature of 130 oC in phosphate buffers within a pH...
Photo-stability of Acid Dyes, Derivatives of 1-phenyl-3-methylpyrazol-5-one in Polyamide Fibers
acid azo dyes photo-degradation light fastness photo-oxidation photofading
2009/2/10
We have examined the photo-stability of acid dyes, derivatives of 1-phenyl-3-methylpyrazol-5-one, in polyamide fibres, including the relationship between the dye’s structure and photo-stability. The p...
