Dyeing 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 کاملDyeing 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 کاملDyeing Properties of Some New Disperse Dyes Containing Piperazine Moiety
Four novel azo disperse dyes based on 1-4-bromobenzyl-4-phenylpiperazine were synthesized in two steps, using alkylation and azo coupling reactions. Chemical structure of the dyes was characterized and confirmed by the Ultraviolet Visible UV-Visible, Fourrier Transform Infrared FT-IR, Proton Nuclear Magnetic Resonance 1H NMR and Carbon Nuclear Magnetic Resonance 13C NMR analyses. The solvatochr...
متن کاملSterilization of Microorganisms with Supercritical Carbon Dioxide
Thc sterilizing effect of supercritical carben dioxide (SC-CO,) is described as compared with gaseous C02(G-CO,) and liquid CO,(L-CO,). Baker's yeast, ltscherichia eoli, Staphylococcus aure us and eonidia'ofAspergiilus niger were sterilized by treating with SC-CO, at 200 atm and 350C when the water contcnt of each microorganism was 70 .90%, However, dry cells with a water content of 2 .1O% coul...
