  Conventionally, dyeing of cotton with reactive dye can be done in the presence of salt to improve exhaustion by reduction the repletion forces in between the anionic dye and hydroxyl functional groups of cotton. But after dyeing salt and hydrolysed reactive dye effluent becomes directly disposed to the environment and critically affect human health and biodiversity live inside water bodies. To eliminate salt consumption and enhance wool waste utilization, the present study focused on an eco-friendly approach of salt free dyeing of cotton with reactive through cationization using extracted keratin hydrolysed from Ethiopian sheep wool waste. Keratin protein was successfully extracted from wool waste using different combinations of NaOH Concentration, Temperature, pH and Time. The optimum extraction parameters were selected by investigating the maximum absorption obtained at λ max un.. Read More»
