METHOD FOR MARKING A TEXTILE THREAD WITH A FLUORESCENT ELEMENT, TEXTILE THREAD PRODUCED BY THE MARKING METHOD, AND USE OF SAID TEXTILE THREAD FOR WEAVING AN ITEM OF CLOTHING

摘要

A method for marking a textile thread by a fluorescent element has the following successive steps: placing a textile thread and at least one fluorescent element in a reaction chamber, introducing a fluid into the reaction chamber, increasing the temperature and pressure in the reaction chamber up to a temperature and a pressure so as to transform the fluid into a supercritical fluid and to mark the textile thread by the fluorescent element. The fluorescent element is chosen from organolanthanide complexes.
