Study on The Reactive Dyeing of Cotton Fabric Using Two Type of Reactive Dyes for Comparing Color Fastness to Light Alom, Md. Jahangir; Hasan, Md. Jahid; Raihan, Md. Abu; Roknuzzaman, Md.; Hossen, Md. Fahad This study investigates the reactive dyeing of cotton fabric using two different types of reactive dyes for the purpose of comparing their color fastness to light, wash, rubbing & perspiration. Cotton samples were dyed under standardized conditions, and the performance of each dye type was evaluated through controlled exposure to light sources. The study focused on the differences in dye–fiber bonding mechanisms and how these impact the durability and stability of color when subjected to light-induced fading. Results indicated that bifunctional reactive dyes exhibited superior light fastness compared to monofunctional dyes, likely due to their ability to form stronger and more stable covalent bonds with cellulose fibers. This research provides valuable insights for textile manufacturers seeking optimal dyeing solutions for enhanced color retention in light-exposed environments

Comparative study on 100% cotton woven & knit fabric with reactive & direct dye. ISLAM, MD.SADEKUL; DEY, TANMOY; AZAD, TANVIR; RANA, MASUD This project report present comparative study about rubbing fastness of reactive dye and direct dye. In this report we collect data from Sonargaon University textile lab. This report, help us to know about rubbing fastness of reactive dye and direct dye. Their dyeing process and fastness properties. From this experiment we also learn that the auxiliary need for dyeing of direct dye is less than reactive dye, but temperature need for dyeing with direct dye is more than reactive dye. Rubbing fastness of dry reactive fabric is better than direct dye. Rubbing fastness of wet fabric of reactive dye for knit and woven fabric also better than rubbing fastness of direct dyed fabric.

Study on Reactive Dyeing of Cotton Fabric using an Ethanol Solvent System. Pappu, Afsarul; Hasan, Ratul; Hossain, Rakib; Mia, Md. Shobuj; Ali, Md. Yousub In this study, an ethanol–water mixture is used as a dyeing medium for cotton fabric with reactive dyes without using salt, soda, or any other auxiliary chemicals. After dyeing, several fastness properties were evaluated, including: Color fastness to wet and dry rubbing Color fastness to washing Color fastness to alkaline and acidic perspiration The results were found to be very similar to those of conventionally dyed samples using water-based systems for reactive dyes. Since ethanol is a green solvent, and the ethanol– water mixture is recyclable, it presents a sustainable alternative to traditional cotton dyeing methods. This approach is expected to contribute positively toward eco-friendly and sustainable textile processing by reducing the environmental impact associated with water and chemical consumption.
