Abstract
Various colors of clothing originating from synthetic dyes are presently causing serious environmental pollution problems, whereas natural dyes extracted from indigo plants help to reduce harm to the environment and extend the sustainable use of clothing. This study focuses on the difference between indigo dyeing colors and the environment on the basis of sustainable design. This study surveyed 105 postgraduates and college students through repeated measurements of ANOVA. The results reveal that light colors are considered to conform to the sustainable spirit more than dark colors in different indigo shades. In fact, a recyclable light-colored indigo-dyed t-shirt is beneficial due to its reusability. Indigo-dyed fabric can be decomposed by a variety of microorganisms; however, light-colored indigo dyeing takes a shorter amount of time. Light-colored indigo dyeing is more resource-saving when considering dye, water and electricity costs. The results of the relationship between colors and environmental protection provide scheme references to consumers or industries for clothing collocation of different indigo dyeing colors for a series of blue clothing, and carry out the idea of sustainability and co-existence between clothing and natural resources.
Highlights
Fast fashion leads the market trend; the use of environmentally harmful chemicals and textile waste accumulation cause the textile industry to remain the second worst polluting industry worldwide [1]
According to trend analysis (p = 0.000 < 0.001), nine colors show linear relationships that indicate that the degree of benefit to the environment of the nine colors decreases gradually seriatim from the light color No.1 (M = 3.95) to the dark color No.9 (M = 2.71)
The results reveal differences among the opinions of participants about the different colors (F = 60.464, p = 0.000 < 0.001) according to the Mauchly Spherical test, indicating that the Spherical test had been violated and the result showed forward bias; the F tests should be adjusted by Geisser–Greenhouse (G–G)
Summary
Fast fashion leads the market trend; the use of environmentally harmful chemicals and textile waste accumulation cause the textile industry to remain the second worst polluting industry worldwide [1]. Based on the idea of environmental friendliness, studies applied many methods including the activated carbon (AC) adsorption process to remove the toxicity of dyeing wastewater, as well as the Temkin adsorption isotherm model to separate yeast indigo dye, Diutina rugosa, and improve the color fastness of indigo to the industry standard with indirect electrochemical reduction, so as to deal with environmental crises [4,5,6]. This current study is interested in discussing the relationship between indigo dyeing colors and the environment. The study further examines different situations involving colors of indigo dye in clothing so as to offer references of color application to indigo-dyed clothing and for the sustainable design of natural resources
