Infinited Fiber Company on how to create a cotton-like fibre from post-consumer textile waste
Created out of biodegradable cellulose and containing no plastic, the company’s patented Infinna fibre is one solution to the industry’s problem with clothing and other textiles ending up in landfills.

Key account director Kirsi Terho describes Infinna as a brand-new textile fibre that looks and feels soft and natural like cotton.

— The fashion and apparel brands we work with, such as Patagonia, Ganni, and H&M Group, also see it as a major benefit that the fibre is really versatile. It works like cotton in the textile manufacturing value chain and can be turned into a whole range of yarns, fabrics, and products — from jeans and T-shirts to dresses and dress shirts, or home textiles like curtains and bedsheets. The beauty of Infinna is also that it can be created 100 per cent out of resources that are already in circulation, she says, adding,

— The technology we use is called cellulose carbamate technology, where we break down the textile waste at the molecular level so that we can clean it of non-cellulosic materials like polyester and dyes and textile finishing chemicals, and then regenerate it back into a brand-new textile fibre.

Infinna is currently completely created out of post-consumer textile waste at the company’s pilot facilities in Finland, which means that the production is still relatively small. So far, two capsules — one with H&M Group’s brand Weekday, and one with Wrangler — have used the fibre, and Infinited Fiber Company is now preparing to build its first commercial-scale factory in Finland. 

— It will have an annual production capacity of 30,000 tonnes, which is equivalent to about 100 million T-shirts. We expect it to open in 2024. At the same time, we’re in talks to license our technology to third parties to enable other fibre producers to add Infinna to their product portfolios and in this way speed up time to market, Terho says.
