Abstract
On décrit un système d'identification de fibres textiles d'acide polylactique (PLA) par ajout lors de la formation de la fibre textile d'un additif ayant des caractéristiques physico-chimiques pouvant être détectées par analyse optique et/ou physico-chimique. Le traceur peut être détecté à chaque étape de production et lors du tri précédant le recyclage.A system is described for identifying polylactic acid (PLA) textile fibers by adding, during the formation of the textile fiber, an additive having physico-chemical characteristics that can be detected by optical and/or physico-chemical analysis. The tracer can be detected at each stage of production and during sorting before recycling.
