Spinnova, the sustainable fiber company, has entered long-term collaboration with the global chemicals company Kemira, to develop a highly eco-friendly inherent dyeing method of fiber.
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 fiber and the possibility of inherently dyeing could be an environmental game changer and could disrupt e.g. 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 fiber maintains this in-built color really well. Spinnova’s innovation originates from the pulp and paper industry, which is also one of the areas of expertise for Kemira and an important focus in the company’s R&D work towards bio-based chemicals.
