Application of biomimicry for sustainable functionalization of textiles: review of current status and prospectus

With the increasing complexity of human lifestyles, the demand for functionalized or high-performance textile materials has seen a steep rise. However, the methods of producing thereof are still creating a negative impact on the environment. Although biomimicry is a possible means of catering for this demand, most of the emerging biomimetic technologies follow an unsustainable path, accentuated only on transferring functionalities of nature, by using chemical-intensive applications. Nevertheless, biomimicry holds promise in sustainable manufacturing, if toxic chemical usage can be reduced while structural applications are increased. This study reviews the possibilities of existing and futuristic textile technologies that could facilitate conscious biomimicking of functional textiles, rather than intense application of chemicals. A total of 283 research articles were initially obtained and screened to review the possibilities of combining biomimetic technologies with textile manufacturing technologies. Prospects of innovative textile technologies and additive manufacturing on the futuristic possibilities of structural mimicking of biological functionalities into textile materials are discussed comprehensively. Possible construction methods, including additive manufacturing and weaving in the micro/nano scale, are suggested for structural mimicking. It is also recommended to unfold the potential of biomimicry in producing functional textiles in order to alleviate the harmful impact already caused to the environment by the textile industry.
