  Dye Summary
Dyes from plants included blue dye from the indigo plant; blue dye from woad; red and brown dyes from the madder plant; yellow, orange, brown, and fl dyes from various trees; orange or red dye from henna; and yellow from safflower and weld.
Dyes were dissolved and applied to the cloth and the color change would take place either because the dye molecules became bonded to the fiber molecules or because the dye was unable to pass out of the fibers' fine capillaries once it is inside of them.
The dye is usually used as an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.

 dye. The Columbia Encyclopedia, Sixth Edition. 2001-05
Natural dyes are so called because they are obtained from plants (e.g., alizarin, catechu, indigo, and logwood), from animals (e.g., cochineal, kermes, and Tyrian purple), and from certain naturally occurring minerals (e.g., ocher and Prussian blue).
Dyes are classified also as acidic or basic according to the medium required in the dyeing process.
A vat dye, e.g., indigo, is so called from the method of its application; it is first treated chemically so that it becomes soluble and is then used for coloring materials bathed in a vat.

 A BRIEF HISTORY OF DYESTUFFS & DYEING
According to Webster’s dictionary, dyeing is “the process of coloring fibers, yarns or fabrics by using a liquid containing coloring matter for imparting a particular hue to a substance.” There are three basic methods of “imparting a particular hue” to a substance.
The great detail in which the preparation of the fibers and the dyeing materials and the dyeing process itself are recorded has led scholars to believe that it had to have been practiced for thousands of years previously in order to raise the process to such a science and art.
It’s use was first recorded in 1727 BCE and it was long the standard red dye for silk, wool and leather, but the intense colorific value and relative cheapness of cochineal soon eliminated most of the kermes use in England, so Spain hung on to control of their lucrative monopoly.

The dye laser is based on the ability of certain organic dyes to absorb the energy of a source and then re-radiate the energy as laser radiation.
When they examined the spectra from their dye cell, they found that instead of the Raman spectra, there was a weak, diffuse band at the peak of the fluorescence bands (755.5 nm).
Incidentally, even the idea that a dye molecule exists in one of four bands is a simplification, since the energy levels of the dye molecules are really broad bands composed of vibrational and rotational levels.

 LEOT Laser Tutorial - Course 3: Laser Technology - Module 10: Liquid Dye Lasers   (Site not responding. Last check: )
Triplet absorption in a flashlamp-excited dye systems is believed to be a major factor in the experimentally observed lack of synchronization between the pump pulse and the laser pulse.
Finally, if water is interposed between the flash lamp and dye cell, the remaining lack of synchronization between pump and laser pulses virtually disappears, presumably because of absorption of the IR components of the flashlamp output by the water.
Thus, a beam-expanding telescope is sometimes used between the dye cell and the grating to illuminate most of the surface of the grating to prevent the formation of "hot spots" mentioned earlier.

 Hair Dye Dilemmas (April 1993)
Some researchers say that extrapolating results from ingested hair dye studies to absorbed hair dye use cannot accurately assess cancer risk because the compounds being tested are altered or are absorbed differently in the gut than they are when applied to the scalp.
Moreover, tests of individual hair dye ingredients don't measure the health hazards of the highly reactive compounds that are formed when the various ingredients in a specific hair dye are mixed together and applied to hair.
Gradual dyes are usually applied daily until a dark enough shade is achieved, after which it may be used less often to maintain the color.

 Orchil Dye
Dyeing cloth and yarn with extracts of plant material is already a very well established process at the beginning of written history.
According to Liles (1990), in about 1908 a German dye chemist, a Dr. Friedlander, was able to gather enough of the pure dye to analyze, and determined that it is actually 6,6'-dibromo-indigo, which produces a deep reddish color.
At the time I was experimenting with these dyes, I knew very little of their history, except that they were obscure and little known (a good recommendation to the curious).

 Sam's Laser FAQ - Home-Built Dye Laser   (Site not responding. Last check: )
Dye lasers are unique in that they are a class of lasers whose lasing medium is a liquid.
For example, Rhodamine-B, a common dye used in dye lasers for the red region, is often pumped with an argon ion laser at 514 nm for CW operation or a doubled YAG laser at 532 nm when pulsed.
If the dye is allowed to absorb this radiation, a VERY strong shock wave appears at the edge of the dye cell wall and travels in toward the center of the dye solution.

 FAQ: Is there any way to "set" dye in purchased clothing?
Vinegar will help set some acid dyes, but only if applied while it is gradually heated to a simmer (generally in the presence of salt), solely in cases in which this necessary part of acid dyeing was omitted; acid dyes are used on silk, wool, or nylon, but never cotton.
Salt can be useful in dyeing, by encouraging the fiber not to repel the dye, or by making the dye less soluble, but it will not itself fix the dye to the fiber.
Dye is always most easily washed out with hot water, though the first washing after dyeing should always be done in cool water, and loosely attached dyes such as direct dye (found, for example, in Rit brand dye and other all-purpose dyes) must never be washed in hot water.
