Résumé : |
Textile fiber production has been increasing dramatically in the past decades, reaching almost 120 million tons in 2020 world-wide. The vast majority of these textile fibers (around 80 %) are disposed of as waste at the end of their use phase, which means that waste textiles are becoming an increasing environmental problem. Currently, the most common practices to manage this waste are landfilling and incineration, which are not particularly sustainable practices and therefore they aggravate the environmental impact of waste textiles. Textile recycling has been suggested as a possible solution to decrease this environmental burden as well as to increase circularity in the textile sector.
There are many different types of textile fibers present in the market : plant fibers, animal fibers, man-made cellulose fibers, fossil-based fibers, etc. This means that waste textiles contain a variety of different materials and therefore their physicochemical properties are far from homogeneous. Even if the different types of fibers are sorted and separated from each other, there could still be differences within the same fiber type. For example, the polymeric chains contained in cotton fi bers could be degraded to different extents depending on the type of washing applied to the material, where industrial washing degrades the polymers the most. |
