Leighton Dye
Leighton William Charles Dye (October 30, 1901 – October 25, 1977) was an American hurdler. He placed fourth in the 110 m hurdles at the 1928 Summer Olympics and was United States champion in 1926.
Biography
Dye was born in St. Louis, Missouri on October 30, 1901. Representing coach Dean Cromwell's USC Trojans, Dye won the IC4A 120 yd (109.7 m) hurdles title as a junior in 1925, running 14.8; USC won that year's IC4A team title. Later that year he placed third at the national championships, behind Olympic finalist George Guthrie and NCAA champion Hugo Leistner. In 1926 Dye repeated as IC4A champion, this time in 14.7, and placed second to Guthrie at the NCAA championships; the Trojans again won the IC4A team title, and would have also won the NCAA title if one had been awarded that year. Dye then won at the national championships in 14.6, equalling both his personal best and Guthrie's meeting record from the previous year.
Dye again ran 14.6, this time for the metric 110 m hurdles, at the 1928 Southwestern Olympic Tryouts, qualifying for the final Olympic Trials; the time broke Earl Thomson's world record for the metric distance of 14.8, although it was still inferior to Thomson's 14.4 for the imperial hurdles and was never ratified as a world record. At the final Trials in Cambridge Dye placed third behind Steve Anderson and John Collier, qualifying for the Olympics.
Dye
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.
Both dyes and pigments are colored because they absorb some wavelengths of light more than others. In contrast to dyes, pigments are insoluble and have no affinity for the substrate. Some dyes can be precipitated with an inert salt to produce a lake pigment, and based on the salt used they could be aluminum lake, calcium lake or barium lake pigments.They are of many types as we know that indigo is a type of plant which was rashly cultivated in bangal by the Britishers as to make different color of dye.
Natural
The majority of natural dyes are from plant sources: roots, berries, bark, leaves, and wood, fungi, and lichens. Textile dyeing dates back to the Neolithic period. Throughout history, people have dyed their textiles using common, locally available materials. Scarce dyestuffs that produced brilliant and permanent colors such as the natural invertebrate dyes Tyrian purple and crimson kermes were highly prized luxury items in the ancient and medieval world. Plant-based dyes such as woad, indigo, saffron, and madder were raised commercially and were important trade goods in the economies of Asia and Europe. Across Asia and Africa, patterned fabrics were produced using resist dyeing techniques to control the absorption of color in piece-dyed cloth. Dyes from the New World such as cochineal and logwood were brought to Europe by the Spanish treasure fleets, and the dyestuffs of Europe were carried by colonists to America.
