Sonicator dyeing of cotton with the leaves extract Acer pectinatum Wallich

Purpose – The purpose of this paper is to evaluate the efficiency of ultrasonication on new natural dye obtained from leaves extract of Acer pectinatum Wallich using metal mordant for good cotton dyeing prospects.Design/methodology/approach – For effective natural dyeing with leaves extract of Acer pectinatum Wallich, both conventional and sonication methods of dyeing were carried out using metal mordants. The purpose of using sonication was for improvement of dye uptake, improved dye adherence and good wash and light fastnesses. Results show marked improvement by the chosen dyeing method.Findings – The superiority of sonicator dyeing over conventional dyeing in terms of enhanced resource productivity and, as a result, reduced wastes establishes it as the best available technique in the natural dyeing industry. Use of sonicator shows marked enhancement for cotton dyed fabric. Typical bath liquor to fabric ratio for conventional dyeing varies from 20:1 to 15:1 and for sonicator dyeing from only 12:1 to 10:...
