The colour of a fabric tells you everything about how it was made. Synthetic dyes tell one story — fast, cheap, chemical. Natural dyes tell another — slow, plant-based, centuries deep. Every piece SA Fab makes tells the second story.
When people search for eco friendly fabric, they are usually looking for something that feels good to buy — a choice that doesn't come with a cost to the environment they can't see. SA Fab's block printed fabric doesn't require a sustainability audit to feel good about. The dye tradition it comes from is inherently ecological — because it has to be. Natural dyes don't work any other way.
This article tells the real story of the six natural dyes used in Bagru's block printing tradition — where they come from, how they work, what colours they produce, and why they matter for sustainable fashion in India.
Why Natural Dyes Matter in Fashion
The textile industry's dirty secret — and Bagru's 450-year answer to it.
Textile dyeing is the second largest source of water pollution globally after agriculture. Synthetic dyes — the kind used in the vast majority of clothing made today — contain heavy metals, toxic fixatives, and chemical compounds that do not break down in waterways. When a factory discharges dye effluent into a river, the river changes colour. Fish die. Communities downstream drink contaminated water.
Natural dye block printing in Bagru has never worked this way. The process uses plant extracts, mineral solutions, and organic mordants — all of which break down naturally in water and soil. The Chhipa artisans who have practised this tradition for generations did not describe it as sustainable fashion because they had no other name for it. It was simply the only way they knew how to work. The ecological benefit was built in from the beginning.
What has changed is that the rest of the fashion industry moved to synthetics, and the contrast became visible. Natural dye block print fabric is now genuinely rare — not as a marketing claim, but as a fact. Most block-printed fabric sold in India today uses synthetic acid or reactive dyes with wooden blocks. The block print is authentic; the dye is not. At SA Fab, both are.
The 6 Natural Dye Sources — Where the Colour Comes From
Plant roots, fruit rinds, mineral solutions — the palette of Bagru's tradition.
01
🌿 Indigofera tinctoria · Plant leaf
Indigo
Source: Indigo plant leaf fermentation vat
Natural indigo comes from the fermented leaves of Indigofera tinctoria — a plant cultivated in Rajasthan and Gujarat for centuries. The leaves are composted in water vats, the blue pigment separates and is dried into cakes. Fabric is dipped repeatedly in the vat to build depth of colour. The more dips, the deeper the blue — from pale dawn wash to deep midnight.
The most iconic colour in Bagru's palette. Used in Ajrakh and indigo prints.
02
🪴 Rubia tinctorum · Plant root
Madder Red
Source: Madder root — dried and ground
Madder root (Rubia tinctorum) has been the source of red dye in South Asian textiles for over 5,000 years. The dried root is ground to powder and cooked into a dye bath. With the right mordant — aluminium alum — it produces the warm, deep terracotta red that characterises Bagru block printing. Without mordant, it produces softer pinks and oranges. The colour warms and deepens with each wash.
SA Fab's signature terracotta — the colour most associated with Bagru prints globally.
03
🌱 Curcuma longa · Rhizome
Turmeric
Source: Dried turmeric root powder
Turmeric (haldi) produces one of the most direct natural yellows available — bright, warm, and solar. The same spice from your kitchen, applied to cotton, bonds with the fibre to produce golden yellows and saffron tones. Turmeric has mild anti-bacterial properties that remain active in the dyed fabric. It is one of the oldest dye sources in Indian textile history — used in ceremonial, festive, and daily textiles alike.
Used for festival yellows, saffron tones, and as an overdye to create warm greens.
04
🍎 Punica granatum · Fruit rind
Pomegranate
Source: Dried pomegranate rind — the outer skin
The thick rind of dried pomegranate (anar) contains tannins that produce warm pink, rose, and soft terracotta tones on cotton. It is also used as a mordant — a fixative that helps other dyes bond more permanently with cotton fibres. In Bagru's process, pomegranate rind is frequently used in the initial fabric preparation before the main dyeing, giving the cotton a warm base tone that improves the depth of every colour applied over it.
The dye behind SA Fab's warm rose and pink tones. Also used as a natural mordant.
05
⚙️ Ferrous sulphate · Mineral solution
Iron Black
Source: Iron sulphate solution — mineral-based
Iron (kale ka paani) is a mineral mordant and dye — iron sulphate dissolved in water reacts with tannins in the fabric to produce deep blacks and charcoal greys. In Bagru, iron solution is applied by block printing onto tannin-treated cotton, creating the sharp black outlines and dark borders that define the classic Bagru print aesthetic. It is one of the few truly black natural dyes — most other plant sources produce only dark blue or dark brown at full saturation.
The sharp black outlines in almost every SA Fab block print come from iron solution.
06
🌿 Terminalia chebula · Seed pod
Harda
Source: Dried seed pods of chebulic myrobalan
Harda (Terminalia chebula) is the foundation step of Bagru's entire dyeing process. Before any block printing begins, the cotton fabric is soaked in a harda solution — the tannins in the seed pod create a chemical bond with the cotton fibres that allows all subsequent natural dyes to fix permanently. Without harda, natural dyes wash out quickly. With it, they last decades. Harda also produces its own colour — a warm pale yellow — which is why all SA Fab fabrics have a slightly warm, living base tone rather than a stark white.
The invisible first step that makes every other natural dye permanent. The foundation of Bagru's eco friendly process.
The colour of a naturally dyed fabric does not fade to nothing. It ages into something — a softer, warmer version of itself that synthetic dyes never achieve.

1
Fabric preparation — Scouring
Raw cotton arrives stiff with sizing agents and natural oils. It is washed thoroughly in hot water to remove all impurities. Clean, soft, fully absorbent cotton is the foundation everything else depends on.
2
Harda mordanting
The scoured cotton is soaked in a harda solution — dried Terminalia chebula pod extract. This deposits tannins into the cotton fibre structure, creating the chemical bonds that allow natural dyes to fix permanently. The fabric comes out pale yellow. This is correct.
3
Block printing — resist or direct
Depending on the print style, the artisan either prints a resist paste (in Dabu printing — a clay and wheat bran mixture that blocks dye from penetrating) or prints dye paste directly onto the fabric using hand-carved wooden blocks. Each block impression is deliberate and manual.
4
Natural dye application
The fabric is immersed in a natural dye bath — indigo vat, madder root solution, pomegranate rind extract, or turmeric bath — and left for a prescribed time. Temperature, duration, and mordant chemistry determine the final colour. This step may be repeated multiple times for depth.
5
Sun drying & colour development
Naturally dyed fabric is dried in open sun — sunlight catalyses the dye-fibre bond, deepening and stabilising the colour. This is fundamentally different from industrial drying tunnels. The sun is part of the process, not just a way to remove moisture.
6
Final wash & finishing
The finished fabric is washed to remove all unfixed dye — this is the colour that bleeds slightly in the first home wash. After this, the colour is stable. The fabric is finished, inspected, and prepared for cutting and stitching.

Bagru's Eco Friendly Tradition — Before It Had a Name
Sustainable fashion is a modern phrase for a very old practice.
The Chhipa community in Bagru has practised natural dye block printing for over 450 years. They did not describe it as eco friendly fabric, sustainable fashion, or slow textiles. They described it as their livelihood — the only craft they knew, passed from parent to child across generations.
The ecological properties were practical necessities. Natural dye effluent could be discharged into the agricultural land around Bagru without killing crops — synthetic dye effluent cannot. The plants used for dye — indigo, madder, turmeric, pomegranate — were grown or traded regionally, not imported from overseas chemical plants. The sun that dried the fabric was free and available. The wooden blocks lasted for decades. The whole system was circular long before circularity became a design principle in global fashion.
What threatens this tradition is not lack of demand — it is price competition from synthetic block print alternatives. A synthetic dye block print can be produced faster, more cheaply, and in colours that are more immediately saturated. When buyers cannot tell the difference, they buy the cheaper option. When they can tell the difference — in hand, in warmth, in the way the colour feels against the skin — they choose the natural dye piece. This guide exists to help you tell the difference.
✦ How to identify genuine natural dye block print
- The base fabric has a warm, slightly yellow tone — from the harda mordant. Stark white base fabric was not natural-dyed.
- Colours shift slightly in different lighting — richer in shade, brighter in sun. Synthetic dyes look the same in all light.
- There is slight variation between impressions of the same block — ink density, a faint double-press, slightly uneven edge. This is handmade.
- The first wash may release a small amount of dye. This is unfixed natural pigment — completely normal, stops after wash 1–2.
- The fabric feels different after washing — softer, more lived-in. Synthetic-printed fabric often feels the same or stiffer.
Caring for Naturally Dyed Fabric
Natural dyes are durable — but they respond to how you treat the fabric.
The most important thing to understand about natural dye fabric India is that the dyes are not fragile — if you know how to treat the fabric correctly. What erodes them over time is the wrong kind of washing: hot water, harsh detergents, and direct sunlight drying.
✦ Care rules for all naturally dyed SA Fab pieces
- Always cold water — hot water breaks the dye-fibre bond over time and shifts warm tones towards grey
- Mild, pH-neutral detergent — harsh synthetic detergents strip natural pigments. Reetha or soap nut powder is ideal.
- Dry in shade — prolonged direct sunlight causes photo-oxidation that gradually fades natural dyes. A shaded breeze dries cotton perfectly.
- First wash separately — there may be slight colour release from unfixed pigment. This is the last of the excess dye leaving the fabric. After wash 1–2, the colour is fully stable.
- Iron on the reverse, medium heat — protects the block print surface and the dye from direct heat contact
Frequently Asked Questions
Common questions about natural dyes and eco friendly fabric.
+
Is natural dye fabric eco friendly?
Yes — genuinely so. Natural dyes are plant or mineral-based, biodegradable, and produced without the petrochemical inputs and toxic effluents of synthetic dye processes. The full natural dye process used at SA Fab — including plant-based mordants, solar drying, and organic fixatives — has a fraction of the environmental footprint of synthetic textile dyeing. It is eco friendly fabric in the most literal sense of the phrase.
+
What natural dyes are used in Indian block printing?
Traditional natural dye block print in India — particularly the Bagru tradition — uses madder root (Rubia tinctorum) for red and terracotta, natural indigo (Indigofera tinctoria) for blue, turmeric (Curcuma longa) for yellow, pomegranate rind (Punica granatum) for pink and rose tones, iron sulphate solution for black and grey, and harda (Terminalia chebula) as the base mordant that makes all other dyes permanent. SA Fab uses all six.
+
Does natural dye fabric fade?
Natural dyes do change over time, but not in the flat, uneven way synthetic dyes fade. A naturally dyed piece that has been washed and worn regularly for years develops a softer, warmer version of its original colour — particularly in indigo and madder. Many people find aged natural dye fabric more beautiful than new. The key factors that preserve colour longest are cold water washing, mild detergent, and shade drying. With proper care, naturally dyed cotton holds its colour beautifully for 10–15 years of regular wear.
+
What is sustainable fashion in India?
Sustainable fashion in India encompasses several distinct traditions — handloom weaving, natural dye printing, organic cotton cultivation, and artisan-direct retail. Natural dye block printing is one of the most direct forms of sustainable fashion because the ecological benefit is inherent to the process rather than added on. Buying a naturally dyed block print from SA Fab supports Chhipa artisan livelihoods in Bagru, keeps a 450-year craft tradition funded and practised, and puts money directly into a production system that has never relied on toxic chemistry.
