Synthetic dyes are hazardous to the environment and humans due their toxic recalcitrant nature. Hence, present study attempts produce eco-friendly dye from sago industrial waste using S. marcescens SS1. The produced by bacterial bioconversion of was characterized GC-MS obtained 13.423 acquisition time, which is similar standard prodigiosin. effects dyeing parameters were optimized for Jute fabr...

Carthamin, the natural dye of carthamus tinctorius (Golrang) was separated by soxhlet extraction and further purified in good yields. Its mordant dyeing of wool, using potassium dichromate as mordant, showed a high washing fastness (above 4). Mordanting by "sweet chrome", "sour chrome", and "reduced chrome" proved that last one to be superior.

Indonesia is among the largest countries in global rice production. Annual generation of straw about 20 million tons were reported. It therefore, utilization as natural dye considered to minimize pollutant problem. Rice composed 48.7% carbon that generate black color. In this research, dyes ash applied cotton and rayon fabrics, followed by mordanting using lime, alum, ferrous sulphate. The colo...

In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...
