Insights
Output (hands- on Inquiry)
Output
-
Material Origins
-
Microbial cultures (Komagataeibacter xylinus)
-
Pure, strong, moldable
​
-
Symbiotic culture of bacteria & yeast (SCOBY)
-
Fermentation process (glucose → cellulose)
-
Water-based growth, low-energy process
-
Natural Dyeing Methods
-
Plant-based dyes (hibiscus, onion, pomegranate, eucalyptus)
-
Enzymatic coloring (laccase + flavonoids)
​
-
Botanical extracts (indigo, madder root, turmeric)
-
Kitchen waste sources (avocado pits, onion skins)
-
Mineral mordants (alum, iron, copper for fixing)
-
Sun-assisted dyeing (solar dye baths)
-
Properties Retained
-
High tensile strength
-
Thermal & mechanical stability
-
Material as Living System → BC behaves like skin, responsive & adaptable.
-
Pigment as Narrative → Natural dyes embed cultural + ecological stories.
-
Circularity in Practice → Waste streams (kitchen scraps, plant residues) become resources.
-
Sustainability & Biocompatibility
-
Fully biodegradable & compostable
-
Eco-friendly alternative to synthetic textiles
-
Design Implications
-
Bio-textiles, vegan leather, fashion futures
-
Aligns with biodesign & eco-innovation
-
Tactile Aesthetics → Unique textures & translucency emerge from dye–material interaction.
-
Scalability Challenges → Growth time & fragility limit mass production.
-
​In this exploration, bacterial cellulose becomes both canvas and content—its microbial purity, dye-compatibility, and ecological footprint converge into a material that is not just seen, but felt. Natural pigments amplify the narrative, while biodesign frames a future where textiles are living, ethical, and intelligent.
