SUSTAINABLE BAND OF SULFUR DYES FOR DYEING TEXTILE AND PAPER ITEMS. The present invention relates to the manufacture of a new group of sulfur dyes in which different species of natural "biomass" are used as raw material, which usually exists in nature and which are transformed into soluble dyestuffs, capable of dyeing textile fibers, preferably fibers and cellulose derivatives, such as cotton, viscose, paper, tencel, with high strength and color fastness properties. For this purpose, the concept of "Biomass" is defined as the residual product obtained from the usual activities of human beings, in agricultural and reforestation sectors. 20198092v1 |
