Dye- Namic Fashion
Designers are opting for natural dyes for garments instead of synthetic colourants, but how eco-friendly is it from sourcing, processing and disposing it
Long before synthetic dyes transformed the textile industry, Indian artisans were turning to nature for colour. Indigo produced deep blues, turmeric offered golden yellows, madder created earthy reds, while pomegranate rind and other botanical materials added different shades to traditional textiles. Today, these age-old techniques are finding renewed relevance in the fashion industry.
However, the return to natural dyes is not as straightforward as replacing a chemical colourant with a plant extract. While natural dyes offer an alternative to petroleum-derived synthetic colourants, their environmental credentials depend on how responsibly they are produced.
Re-dye-fining Fashion
Bhoomi Dave, Associate Professor of Textile Design at Pearl Academy, Mumbai says, “From a textile artisan’s point of view, a garment should be judged as a complete object—not only by the fibre named on its label. The dye, mordant, sewing thread, finish, elastic, print and fastenings all determine whether it can safely return to the earth.”
Natural Dyes
Natural dyes are obtained from renewable biological sources such as plants, roots, flowers, leaves, fruits and bark. Sourcing these materials requires resources, and increased demand can put pressure on agricultural land and wild plant populations. Dave points out that “the land, water and labour required to grow or collect plants that are used for dyeing” are among the challenges preventing natural dyes from becoming mainstream. Seasonal variations can also affect colour consistency.
The process of fixing colour onto fabric presents another environmental consideration. Mordants are substances used to help dyes bond with fibres, and their selection can influence the environmental impact of the dyeing process. “Alum and iron are commonly used by responsible natural dyers, but even these require controlled quantities and responsible wastewater treatment,” Dave explains. She cautions against the use of heavy-metal mordants such as chromium, copper and tin, which can create toxicity concerns.
The dyeing process may involve repeated baths, heating and washing, adding to water and energy consumption. Therefore, a botanical pigment is not automatically harmless simply because it originates from a plant. Its environmental impact depends on how the material is sourced, processed and disposed of.
Colour-fastness Challenge
One of the biggest challenges with natural dyes is maintaining consistent colours across production batches. Differences in plant varieties, growing conditions, extraction techniques and dyeing methods can result in variations in shade. While these differences may be appreciated in handcrafted textiles, they can become a hurdle for brands working towards uniform collections.
However, natural dyes can compete with conventional colouring methods when the fibre, dyeing technique and after-treatment are properly selected. Indigo, madder, pomegranate rind and tannin-rich dye systems can provide good results when skilfully processed. More fugitive dyes may require acceptance of graceful fading. Archana Jaju, a creative director, who has worked with handloom textiles and hand-painted Kalamkari says, “It is important to understand the material we work with and make thoughtful choices at every stage.”
Garment Beyond The Label
The sustainability conversation becomes more complicated when the entire garment is considered. Cotton, linen, hemp, jute, wool and silk can biodegrade under suitable conditions. Regenerated cellulosic fibres such as viscose, modal and lyocell can also break down biologically. However, synthetic fibres such as polyester, nylon, acrylic and elastane do not readily biodegrade.
Polyester stitching, plastic buttons, synthetic linings, elastic, embroidery threads and chemical coatings may remain long after the main fabric has deteriorated. Chemical finishes such as wrinkle-resistant treatments, antimicrobial coatings and water repellents can interfere with microbial activity.
Deepra Gagneja, Founder of Ambrea Image Consultancy and an alumna of the London College of Fashion recommends natural fibres such as cotton, linen, pure silk, wool, jute and hemp. “Plant-based fabrics like lyocell are also worth exploring,” she says.
She also cautions consumers against greenwashing. “A brand may use earthy colours, leaf motifs or green packaging to create the impression that a product is sustainable, but that does not necessarily tell you anything about how it was made.”
Check Certifications
Consumers should check manufacturing information and certifications such as GOTS, OEKO-TEX and applicable Ecocert standards. She says, “Bamboo, for example, is often promoted as a sustainable fabric, but most bamboo textiles are processed into rayon or viscose, which can involve chemicals and significant resource use. Similarly, recycled polyester makes use of existing plastic but remains a synthetic fibre that can release microplastics during washing.”
Moving natural dyes from small artisan practices into larger production systems remains a challenge. Limited availability of raw materials, skilled labour requirements, higher costs and difficulties in achieving consistent shades can make natural dyeing more expensive than conventional alternatives. Jaju says, “One of the biggest challenges is making responsible material choices viable at scale while maintaining quality, consistency and affordability.” India has a rich textile heritage, from handloom weaving to traditional hand-painted techniques such as Kalamkari, which reminds us of the value of skill, time and mindful production. For Gagneja, this shift also needs to begin with the way consumers approach their wardrobes. “Start slowly. You do not need to replace your entire wardrobe or buy everything in natural fabrics overnight. Sustainability should also make sense for your budget, lifestyle and personal style,” she says. She believes versatility is equally important. “A well-chosen garment that you enjoy wearing for years is often a better investment than something you replace after a few uses.”
A Thoughtful Shade
Natural dyes offer fashion an opportunity to revisit traditional materials and techniques at a time when the environmental impact of textile production is receiving greater attention.
Perhaps the future of fashion’s natural dye experiment lies in understanding that sustainability is not about finding one perfect ingredient or process. It is about making better decisions at every stage, from the source of the pigment to the final stitch. Nature may provide the colours, but ensuring that the process does not cost the earth remains the industry’s responsibility.
