Researchers at the University of Alberta are spearheading a groundbreaking initiative to revolutionize the textile industry by transforming agricultural straw into versatile, environmentally friendly fibers. Led by textile scientist Patricia Dolez from the Faculty of Agricultural, Life & Environmental Sciences, the project holds immense promise for creating a sustainable alternative to traditional textile materials while bolstering Canada's bioeconomy.
The research focuses on harnessing cellulose, a natural compound present in all plants, to develop specialized fibers suitable for a wide range of applications, from dental floss to durable workwear. By exploring innovative methods for processing and manufacturing cellulose-derived fibers, the team aims to contribute to environmental conservation, economic growth, and the revitalization of Canada's textile manufacturing sector.
Central to the project is the production of lyocell, a man-made fiber known for its sustainability and versatility. Derived from cellulose, lyocell offers a renewable alternative to conventional textile materials and can be manufactured using a solvent that is almost 100 percent recoverable, minimizing environmental impact. Moreover, by utilizing agricultural straw—typically left unused in fields—lyocell production presents an opportunity to repurpose agricultural waste and reduce reliance on non-renewable resources.
Lelia Lawson, a PhD student involved in the research, highlights the potential of Canadian-grown hemp as a key source of cellulose for the lyocell process. Unlike traditional sources such as eucalyptus trees and bamboo plants, hemp thrives in Canada's climate, offering abundant biomass for fiber production. The research team is exploring ways to optimize the selection of hemp varieties to enhance fiber strength and performance.
The research, which commenced in 2023, is conducted at the U of A's Biorefining and Conversions and Fermentation Laboratory and the Protective Clothing and Equipment Research facility. In collaboration with industry partners and funding support from Alberta Innovates Agri-Food and Bioindustrial Innovation Programme, Bioindustrial Innovation Canada, and PrairiesCan, the project aims to develop patented technology that can revolutionize Canada's textile manufacturing landscape.
Jane Batcheller and David Bressler, both researchers at the University of Alberta, contribute their expertise to the project, further advancing its potential impact. With industry partners such as Davey Textile Solutions Inc, Mark’s, Techfibre Industries, and Plantae Technologies, the research endeavors to create a sustainable supply chain for lyocell fibers, catering to domestic and international markets.
As the research progresses, the team anticipates the development of innovative textile materials that offer superior performance and environmental sustainability. With the potential to address global demand for cellulose-based textiles and diversify Canada's bioeconomy, the project represents a significant step towards a more sustainable and resilient future for the textile industry.
