ABSTRACT
This paper explores the production, properties, and applications of bacterial cellulose textiles within the context of architectural fabrication, emphasizing their potential as sustainable, biodegradable materials. Bacterial cellulose, synthesized by microbial organisms, offers remarkable mechanical properties, high tensile strength, and biocompatibility, making it a promising alternative to traditional materials. The research investigates the complete production cycle, from cultivation using kombucha-based media to post-treatment processes, including washing, stiffening, and dyeing. Methods for enhancing material performance, such as glycerol treatment and duration of sodium bicarbonate baths, are analyzed for their impact on flexibility, texture, impacts on fabrication. Additionally, the paper examines digital fabrication techniques, including laser cutting, and traditional casting methods to create both rigid and flexible structures.
Bacterial cellulose (BC), a biopolymer synthesized by certain types of bacteria, is recognized for its sustainability, biodegradability, and non-polluting characteristics. The production process of BC is environmentally friendly, as it can be derived from agricultural waste, thereby employing circular economy principles. Furthermore, BC does not contribute to environmental pollution, making it a viable alternative to traditional materials and has the potential to be biodegraded over short periods of time.
The study applies these methods to develop bio-leather substitutes and three-dimensional structures, such as flexible tapestries and rigid minimal shell structures. Key insights include the effects of processing variables on material behavior, such as nutrient composition, treatment duration, and post-processing techniques, which influence the material’s adaptability to various applications. The research also integrates natural and synthetic dyes to expand the aesthetic possibilities of bacterial cellulose, demonstrating its potential in interior design and temporary architectural solutions. The presented case studies look at interior applications of soft tensile materials and lightweight structures.
