当前的纺织品生产和加工实践为材料提供了理想的性能，例如拉伸和水分管理，但这些过程是全球温室气体排放、微塑料污染和有毒废水的主要贡献者。幸运的是，支持向可持续循环材料经济转型的当前纺织纤维的绿色替代品已经触手可及。纳米、微米和宏观尺度的纤维生物工程为改善纺织材料的环境影响和技术性能提供了多种途径。在此，我们概述了最近从生物聚合物成分到生物制造方案的生物工程纤维和纺织品的努力。其中包括用于生物制造的微生物基因工程、原材料的绿色化学加工以及绿色制造技术。本概述为可持续生物纺织品生产的未来前景进行了讨论，重点是利用废物流来提高工艺的循环性和商业可行性。
Current textile production and processing practices provide materials with desirable performance properties, such as stretch and moisture management, but these processes are leading contributors to global greenhouse gas emissions, microplastic pollution, and toxic wastewater. Fortunately, green alternatives to current textile fibers that support a transition to a sustainable, circular materials economy are within reach. Bioengineering of fibers at the nano-, micro-, and macroscale provides several avenues to improve both the environmental impacts and technical performance of textile materials. Herein, we provide an overview of recent efforts to bioengineer fibers and textiles from the biopolymer components to biofabrication schemes. These include the genetic engineering of microorganisms for biofabrication, green chemistry processing of raw materials, and green manufacturing techniques. This overview informs a discussion on the future outlook of sustainable biotextile production, with a focus on utilization of waste streams to both improve the circularity and commercial viability of the processes.
