Textile History, 2019
The coloration of textiles goes back to pre-history. However, it can be difficult to research and write about, because it is hard to be confident that we are talking about the ‘right’ — or original...

Dye or not dye, the cryoablation dilemma
Journal of Cardiovascular Electrophysiology, 2019In this issue of the Journal, Hasegawa et al. report the results of a prospective randomized study with the comparison between the pressure wave approach as alternative modality to assess pulmonary vein (PV) occlusion and the conventional strategy of contrast injection to guide cryoballoon pulmonary vein isolation.

Dye Application, Manufacture of Dye Intermediates and Dyes
2007It is difficult if not impossible to determine when mankind first systematically applied color to a textile substrate. The first colored fabrics were probably nonwoven felts painted in imitation of animal skins. The first dyeings were probably actually little more than stains from the juice of berries.

Dye Application, Manufacture of Dye Intermediates and Dyes
1992Sir Isaac Newton’s discovery that white light that is passed through a prism separates into a spectrum of colors proved that light is the source of all color. Light is comprised, in part, of various wavelengths of radiant energy. The human eye, with its marvelous physiology of cones, interprets the wavelengths from 400 to 700 nanometers (a nanometer ...

Model dyes for optimizing the dyeing of polyamide
Journal of Chemical Technology & Biotechnology, 1991AbstractModel disperse azo dyes, containing a salicylic moiety, hydrophobic alkyl chains and usual substituents, allowed the investigation of the effects of these structural variations on dyeing properties.By combining the results of both equilibrium and rate studies, some interesting structures for practical purposes could be identified.

Dyeing is described as the creating of a new and permanent color, by impregnation of especially a dye onto any material namely, textiles, paper or leather. Cochineal, madder, alkanna, henna, brazilwood, red sandalwood, safflower, indigo and logwood were used for the dyeings which can be carried out directly or after mordanting. The goal of dyeing is to

Disperse Dyes: Dyeing Properties and Fastness of Azo Dyes
Textile Research Journal, 1977The dyeing properties and fastness of several disperse azo dyes, prepared from the o- and m-substituted p-nitroani-lines as diazo components and N-ethyl-N-cyanocthylanilinc and - o-anisidine as coupling components, have been studied in order to get an idea of the substitutional effect on dyeing properties.
