Abstract
The objective of this research paper is to establish a suitable reactive dyeing process for banana fiber and comparison between dyeing behaviors of banana fibers with cotton fibers. Ambon (Cavendish type) banana variety was selected for this research study. Data accumulation is done by quantitative research methodology and experimental research strategies for this investigation; 5% enzyme and 6% H2O2-, 2% Na2SiO3-, and 3% NaOH-treated banana fibers were dyed with reactive dye. Banana fibers were dyed with three standard colors (red, blue, and yellow) each with four different concentrations (0.25, 1%, 4%, and 6%) of reactive dye. Testing was conducted to assess the color properties between pretreated banana fiber, dyed banana fiber, and cotton fiber. Color measurement was performed by using a Datacolour 600 spectrophotometers. The ΔE* values were used to determine the degree of color deterioration. Results showed that pretreated fibers become brighter (whiteness) than the raw banana fibers. Reflectance curves of dyed banana fibers were found similar to cotton in all the experiments and confirming the dye absorption tendency is more similar to cotton. Further results indicate that the dyeing behavior of banana is similar to cotton. Therefore, cotton dyeing process can be applied for the banana fibers. Dyeing of banana fiber was carried out with a reactive type of dye, which provided better washing fastness properties than cotton fibers.
Highlights
Sustainable natural fibers have remarkable exhibitions as their method for increasing the value of the textile and apparel manufacturer presents awareness for the consumers.[1]
The main problem to be encountered during dyeing process of banana fiber is the cementing material of lignin which interferes with the absorption property
Pretreatment process removed lignin impurities, which is proven that banana fiber dyeing behaviors are more similar to cotton dyeing
Summary
Sustainable natural fibers have remarkable exhibitions as their method for increasing the value of the textile and apparel manufacturer presents awareness for the consumers.[1]. Farmers cultivating bananas endured such sort of challenges To resolve their problem, the methodology of separating the banana stem and changing it over as a fiber through basic machinery, enzyme, and chemicals is proposed.[5] Banana pseudostem consists of 13 layers of the sheath, and an outer layer of 11 leaf sheaths in the pseudostem can be utilized for extracting fibers.[6]. The recent studies have demonstrated the banana fiber tensile strength, functional chemical group analysis, morphology analysis, water absorption properties, and spinnability properties. This experiment aims to evaluate the suitable dyeing process for the banana fiber and present work focused on the comparison between dyeing behavior of banana fibers with cotton fibers. The effect of dye concentration between banana fiber and cotton fiber samples colorimetric (CIELAB) values and washing fastness properties were studied
