The huge global textile market is increasing steadily by increasing the population and growing demand. The textile industry is the main source of income in some countries and plays a vital role in the economy.

The high profitability of the textile industry often comes at the price of polluting the environment because of the remaining chemicals in wastewater.

The motivation for developing green and sustainable textile processes is to promote the bioeconomy of Finland by working on the whole value chain of recently developed man-made cellulose fibers in the country and expand their portfolio.
