Neri Oxman Grows Color Into Fabric Using Bacteria

Neri Oxman's New York-based design studio, Oxman, has developed a novel method for coloring textiles by "growing" hues directly into the fabric using engineered bacteria. This innovative process, demonstrated on four silk capes, bypasses traditional dyeing techniques, which are known for their significant environmental impact. The capes exhibit uneven coloration, with deep indigos, blacks, and blues appearing in ridges and valleys of the silk, a characteristic that would be considered a defect in commercial dyeing but is intentional in Oxman's "Vigils" project. The colors were developed over 24 hours by billions of E. coli bacteria that Oxman's team of designers and scientists genetically engineered.

Neri Oxman, a former professor at the MIT Media Lab and founder of Oxman in 2020, aims to provide a radical alternative to the apparel industry's conventional dyeing methods. Her work challenges the fashion industry's reliance on extracting and exploiting natural resources, proposing a future where fashion co-creates with nature in mutually beneficial ways. Oxman articulated this vision, stating, "There’s a wide array of relationships between design and nature spanning extraction and generation." She elaborated on the spectrum of possibilities, from extracting dyes from natural sources like flowers to replicating genetic codes in bacteria to produce specific colors.

The environmental toll of traditional textile dyeing is substantial, with the industry accounting for up to 20% of the world's industrial water pollution. This translates to an estimated one trillion gallons of polluted water discharged annually into the oceans. While other biotechnology firms are focusing on integrating cleaner chemicals into existing dyeing infrastructure, Oxman's approach represents a more fundamental reimagining of the dyeing process. By treating dyes and fabrics as living organisms capable of generating color, her studio is pioneering a bio-integrated design philosophy. This method not only addresses the pollution associated with conventional dyeing but also explores a symbiotic relationship between design, biology, and material production, moving towards a more regenerative and less extractive model for fashion.

The "Vigils" project specifically showcases the potential of this bio-fabrication technique. The engineered E. coli bacteria are not merely a source of pigment but are integrated into the material's creation, suggesting a future where textiles are grown with inherent color properties. This approach aligns with a broader movement towards sustainable and bio-based materials in design and manufacturing, potentially reducing the chemical footprint of the fashion industry and fostering a more harmonious relationship with ecological systems. The uneven, streaked, and faded appearance of the colors on the silk capes is a deliberate aesthetic choice, highlighting the organic and living nature of the coloring process and distinguishing it from the uniform, often artificial, finishes achieved through chemical dyes.
