We assess the biodisintegration of textiles directly in seawater. We assess the rate of biodisintegration of textiles after each of the various chemical treatment steps they go through, from the raw material to the material with finishes. We aim at identifying whether a particular step has more impacts than others on the property to biodisintegrate, which could play a role in circular solutions.

This research aims at assessing the biodisintegration of textiles made with natural or wood-based fibers, directly in seawater. At Dornbirn 2023, we showed that textiles made with natural fibers can take much longer to biodisintegrate when comparing virgin material to fashion-ready material (thus dyed and with functional finishes). Here, we assess the biodisintegration of textiles after each of the major steps of their chemical treatment, from virgin to various finishes. The goal is to identify whether a particular step of chemical treatment is responsible for the delayed biodisintegration. Knowing this would allow the industry to find alternative steps to that particular treatment, with the goal to preserve the biodisintegration properties of natural materials.
