Abstract
Several studies report the potential of bacterial cellulose (BC) in the fashion and leather industries. This work aimed at the development of BC-based composites containing emulsified acrylated epoxidized soybean oil (AESO) that are polymerized with the redox initiator system hydrogen peroxide (H2O2) and L-ascorbic acid and ferrous sulfate as a catalyst. BC was fermented under static culture. The polymerization of the emulsified organic droplets was tested before and after their incorporation into BC by exhaustion. The composites were then finished with an antimicrobial agent (benzalkonium chloride) and dyed. The obtained composites were characterized in terms of wettability, water vapor permeability (WVP), mechanical, thermal and antimicrobial properties. When AESO emulsion was polymerized prior to the exhaustion process, the obtained composites showed higher WVP, tensile strength and thermal stability. Meanwhile, post-exhaustion polymerized AESO conferred the composite higher hydrophobicity and elongation. The composites finished with the antimicrobial agent showed activity against S. aureus. Finally, intense colors were obtained more uniformly when they were incorporated simultaneously with the emulsified AESO with all the dyes tested.
Highlights
An emerging trend within the fashion fabric industry concerns the eco-friendliness and sustainability of the production of fabrics in using bio-based materials or products derived from renewable resources with properties interesting enough to warrant commercial viability
The groundbreaking concept of self-grown fabrics from natural renewable resources such as bacterial cellulose, seaweed, algae, kelp, fungi and mycelium, has increased collaborative efforts between designers and scientists to explore the use of these natural green materials in textiles
We review the scientific work carried out within the scope of the application of bacterial cellulose (BC) in the textile and fashion industry
Summary
An emerging trend within the fashion fabric industry concerns the eco-friendliness and sustainability of the production of fabrics in using bio-based materials or products derived from renewable resources with properties interesting enough to warrant commercial viability. BC presents unique properties including high crystallinity [3], high specific surface area [4], high water absorption [5]. The unique structure and impressive physico-mechanical properties of BC have supported the development of several applications in different areas, such as food packaging [7,8], biomedical [9,10], cosmetics [11], filtration [12,13] and electronic devices [14,15]. BC is emerging as a potential alternative to conventional woven/leather materials. The German start-up ScobyTec developed a vegan alternative to leather made of BC produced from kombucha, which was used to make various products such as gloves, children’s shoes and business handbags.
