Study of Dyeing With Natural Extract of Butterfly Pea Flowers (Clitoria Ternatea) on Cotton Fabrics

Objective: This study aims to optimize the dye extraction and dyeing variables in cotton fabrics using dried Butterfly Pea flowers (Clitoria ternatea), in order to evaluate its potential as a natural dye in the dyeing of cotton fabrics. Theoretical Framework: This research is presented based on fundamentals related to dyeing with natural dyes, dye extraction and pre-mordanting procedures, as well as studies related to the dyeing of cotton fabrics. Method: This research was carried out by varying the dye extraction temperature and dyeing parameters, which were documented and optimized. The pre-mordanting process was also used with 5 different biomordants, at the end the washing and friction fastness properties of the fabrics dyed with and without the pre-mordanting process were observed. Results and Discussion: The results showed that the best dye removal temperature was 70°C and the optimized dyeing conditions were a temperature of 50°C, time of 60 minutes and pH 3. In general, the use of biommordants did not promote improvements in solidity interactions. Research Implications: The use of natural dye made from Butterfly Pea flowers in dyeing provides a blue color to the cotton fabric, which is difficult to achieve. Originality/Value: The use of natural dye made from Butterfly Pea flowers in dyeing provides a blue color to the cotton fabric, which is difficult to achieve.
