Research on the Dyeing Process of Lotus Shell Cotton Fabrics
The article primarily delves into the optimal extraction process of lotus shell pigments through aqueous extraction and their dyeing performance on cotton fabrics.Employing a single-factor experimental approach,it establishes the best extraction conditions for lotus shell pigments and the optimal direct dyeing process.By testing the K/S value of dyed cotton fabrics,the study analyzes the dyeing effects of different metal mordants and their corresponding pre-mordant,same-mordant,and post-mordant dyeing methods.The results indicate that the optimum extraction time for lotus shell pigments is 120 minutes,the optimal extraction temperature is 80℃,and the ideal amount of lotus shell powder is 5 g/50mL.On cotton fabrics,the optimal dyeing conditions include a dye concentration of 200%,a temperature of 90℃,and a dyeing time of 70 minutes.Iron ion mordanting significantly influences the color of cotton fabrics,while post-mordanting is the most effective method for controlling color depth.The dry,wet rubbing,soap washing,and light fastness test values of all mordanted samples meet production requirements.
