| Popis: | Pineapple leaf fiber is an environment-friendly natural fiber that does not harm any natural substance. To produce commercially available and attractive textile materials, pineapple leaf fibers were bleached with hydrogen peroxide and colored with natural dyes. Four natural dyes (turmeric powder, ebony fruit, lac, and sappan wood) were selected as natural sources for the extraction of natural colorants with and without salt, alum, and lime as mordants. The hydrogen peroxide concentration of 10 %owf, liquor ratio of 1:100, contact time of 30 min, and bleaching temperature of 70 °C were found to be the optimum bleaching parameters. The uses of different types of mordant on natural dyes give a variety of shades. The positive value of color axes (a* and b*) was an affirmation of mixture of red and yellow colors of mordanted-dyed PALF. PALF displayed a satisfactory dyeing performance for ebony fruit extracted dye with adequate fastness properties (from good to excellent) for light, wash, and perspiration, whether unmordanted or mordanted. Meta-mordanting increased the colorfastness properties of the samples. Results show excellent coloring ability for pineapple fiber dyeing, which can be a potential substitute for synthetic fiber as a sustainable approach to clean production. |
