“…The spectrophotometer measured raw banana fiber, dyed fiber, and cotton fiber samples' reflectance factor and evaluated the color deviations of ΔΕ* values obtained by CIELab (L*, a*, b*, c*, and h) color system. 17 The lightness-L* and the chromaticity coordinates a*-green/red, b*-blue/yellow, C*-chroma, and h-hue angle color parameters were assessed. According to American Association of Textile Chemists and Colourists (AATCC) test method, color value was evaluated as 173-2006 in illuminant D65, large area view, and International Commission on Illumination (CIE) 10° standard observer.…”

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.

“…Its process pollutes both water and the environment with toxic waste. The World Bank considers that 17 to 20% of industrial water pollution comes from textile dyeing and from the finishing treatment given to the fabric [3][4][5]. It is estimated that 150 L of wastewater is generated to produce one kilogram of the finished product in the textile industry and certain synthetic dyes present are not biodegradable or remain in the environment for a long period, causing pollution.…”

“…It is estimated that 20% of used dyes are dumped into the environment because of their low level of affinity with the fabrics [8]. On the other hand, natural dyes come from renewable, ecological, safe, non-carcinogenic, non-allergenic and biodegradable sources [4,9].…”

Biomordants and new alternatives to the sustainable natural fiber dyeings

The textile industry is considered a major polluter of the environment using chemical substances such as color fixatives and the production of toxic waste. There is a growing demand in the fashion market for products that are less aggressive to the environment and use of environmentally friendly processes. Considering the use of natural dyes as an alternative to synthetic dyes, and the use of natural mordants as alternatives to metal mordants, this study investigated the use of Acacia mearnsii sawdust as a biomordant for color fixation. Dyeing and color fixing tests were carried out on banana fiber, and the natural dyes of Hibiscus sabdariffa, Allium cepa and Curcuma longa. The results show the efficacy of Acacia as a biomordant for the tested dyes, presenting intense color and fiber softness. Thus, it is intended to contribute with new alternatives to natural dyeing through materials and sustainable processing procedures applied to natural fibers.

Water is the ultimate and mostly used media during textile materials processing, especially in colouration. This study investigated the possibilities of using seawater for cotton and polyester fabrics dyeing. Single jersey fabrics made of 100 percent cotton and polyester were dyed using a standard recipe and two separate water source as dyeing mediums. It has been focused on the assessment of colour fastness to wash, perspiration, saliva, rubbing, water, light and colour difference value due to compare the efficiency of dyeing media. The results revealed that the cotton fabric dyed with seawater showed lighter shade than that of ground water sample. But for polyester fabric darker shade was obtained compared to ground water. The cotton sample dyed with sea water carried about 15% higher colour strength than ground water dyed sample but for polyester it was very negligible, only 3%. Moreover, the results of colour fastness to wash, perspiration, saliva, rubbing, water and light for seawater dyed samples of cotton and polyester were shown satisfactory outcomes having the grading of 4–5 in most of the cases. This exploration established that commercial dyeing processes were robust and can be practically transferable into the seawater medium for cotton and polyester fabrics.
