Spinnova, a Finland-based sustainable fibre company, has announced that the company entered a long-term collaboration with the global chemicals company Kemira, to develop a eco-friendly inherent dyeing method of fibre. Company suggested that dyeing fibre in its manufacturing process could significantly benefit both the textile industry and the environment.

“Kemira has strong expertise in the chemical applications for the pulp and paper industry and a long history of enabling raw water, energy, and resource efficiency for our customers. In collaboration with Spinnova, we can extend our unique know-how into the development of new innovations in the textile industry; not only in dyeing but also to improve other properties of sustainable textile fiber, such as hydrophobicity and strength,” Kemira’s director of global business development, Mats Berg, said in a press release.

Inherent dyeing in the Spinnova process means that the cellulosic fibre mass is dyed before extruding into filament. This avoids the excess use of water, energy, heavy metals and other harmful substances that go into dyeing fibre, thread and fabric as subsequent processes.

 

Spinnova’s sustainable fibre and the possibility of inherently dyeing the fibre could be an environmental game changer and could disrupt eg the denim dyeing process. The textile dyeing and finishing industry is one of the most chemically intensive industries globally, and one of the worst polluters of fresh water. The traditional textile industry uses thousands of chemicals in various processes of manufacture, including dyeing and printing.

“In addition to being the most sustainable way of dyeing, the fibre maintains this in-built colour really well. We have already made some successful trials, and the results are very promising,” Spinnova’s CEO and co-founder Janne Poranen, said in a press release.

We have returned to our roots in a way, to improve the quality of the product we have created, while maintaining our zero tolerance on harmful chemicals.”
