Investigating the Demand of Various Dyes used for Cellulosic Fiber: A Survey-Based Study of Dyeing Industries in Bangladesh

Bangladesh is one of the world's top exporters of ready-made clothing, and the country's textile dyeing industry is a vital part of its garment manufacturing sector. With an emphasis on reactive, direct, vat, sulfur, basic, and pigment dyes in the woven, knit, yarn, and jute dyeing industries, this study methodically examines the demand and consumption patterns of several dye classes used for cellulosic fiber dyeing. Ten woven dyeing companies, twenty-eight knit dyeing factories, eight yarn dyeing factories, and three jute dyeing factories were among the 49 dyeing enterprises in Bangladesh that participated in a thorough survey. To ascertain the percentage use of each dye class, quantitative data on monthly dye consumption (in metric tons) were gathered and examined. The findings clearly show that reactive dyes dominate all industry types: knit dyeing factories used only reactive dyes (100%), whereas the woven, yarn, and jute dyeing sectors recorded reactive dye shares of 61.09%, 95.86%, and 51.11%, respectively. Reactive dyes' strong performance attributes, such as their compatibility with cellulosic substrates, moderate-to-high exhaustion rates (50–95%), and outstanding wash fastness (grade 3 and beyond), were found to be the main causes of their extensive use. The results offer quantitative proof for resource planning, environmental impact evaluations, and dye market dynamics in Bangladesh's textile industry. For dye house managers, supply chain planners, and legislators involved in sustainable textile production, this report is a fundamental resource.
