Fluorescence measurements have been advanced on cellulose models before and later dyeing. The emission spectrum of the nondyed cellulose fbers not demonstrate any bond and, in the opposing, dyed cellulose sample existing important photoluminescence characters and the maximum value was noted at 672 nm.

INTRODUCTION Until the end of the last century, natural dyes were the only source of color for all textiles commonly used by humans. These dyes were also used for dyeing wood, feathers, etc., and they provided part of the pigments used in painting and were also of great importance in cosmetics, pharmaceuticals and food. Unlike synthetic dyes, natural dyes usually do not consist of just one coloring molecule. They almost always result from a combination of several coloring molecules, usually from different chemical groups. This gives them a subtlety of unparalleled tones which explains why the artisan dyers of many civilizations have remained attached to the use of natural dyes for their most prestigious textile productions or those most loaded with symbolic and religious meaning. However, the accidental discovery in 1856 of a synthetic dye, mauveine, initiated the end of the traditional art of dyes, especially since they present a diffculty in standardizing and reproducing the results. Therefore, the transition to synthetic dyes was rapid as the new dyes were safe, convenient, and generally less expensive industrially. The natural dye is combined in the human mind with the notions of environmental and physiological consciousness. This idea alone is suffcient to explain the rebirth of this art, as well as the marked tendency of several researchers to switch from a natural artisan dye to an academic
