A NOVEL INDUSTRIAL METHOD FOR DYING NATURAL, SYNTHETIC AND BLENDED FABRICS WITH NATURAL DYES UNDER LOW TEMPERATURE CONDITIONS

THIS IS A NEW DEVELOPED METHOD FOR DYING NATURAL FABRICS, SYNTHETIC FABRICS AND THEIR BLENDS FABRICS WITH NATURAL DYES UNDER LOW TEMPERATURES IN CLOSED DYING CONDITION THROUGH TREATING THE FABRICS WITH SOME METAL SALTS, WHICH HELP IN SOLUBILITY OF DYE AND FIXED IT ON THE FABRICS. IT IS WORTHWHILE TO MENTION THAT IN THIS METHOD ALL DYING AND FIXED PROCESSES DONE ON LOW TEMPERATURE AROUND 40 ْ C, SO THE DYING COST HERE WAS LOW AND THE ECONOMIC GAIN WAS HIGH. WHILE IN TRADITIONAL METHODS THE TEMPERATURE OF DYING AND FIXED PROCESSES DONE ON HIGHER THAN 80-100 ْ C, SO THE DYING COST BECOME HIGH AND THE ECONOMIC GAIN WAS DECREASE COMPARED WITH THE NEW METHOD
