Per-acetic acid effect on separation of banana fiber and their dyeing with natural dyes

Abstract

The fiber derived from the pseudo-stem of the banana plant is the subject of this investigation. It describes the processes involved in creating pseudo-stem fiber from bananas, such as fiber extraction, retting, and degumming. Banana fiber has been separated using per-acetic acid. To evaluate the efficacy of the process, the fiber's appearance and form have been altered. A homogeneous, spotless surface was observed under Scanning Electron Microscopy. Weight loss is the outcome of the treatment and absorbency increases. 3.66% of the weight loss is attributed to the per-acetic acid treatment. The fiber’s average diameter was reduced 81.9% compared to the raw fiber. Fourier transform infrared spectroscopy analysis was utilized to assess the chemical changes brought about by the treatment, which verified the presence of cellulose in the fiber. The separated fibers were colored using natural dyes, which were then assessed based on how well they characterized the color. The results demonstrated the use of natural colors derived from extracts of madder and myrobalan. The standard test indicates that ferrous sulfate (FeSO4) exhibits strong resistance to light, washing, and rubbing fastness, making it a viable mordant for achieving brown to black color.Graphical
