There is described a process for colouring elements made of polymeric material, in particular yarns produced selectively in polyethylene (PE), in ultra high molecular weight polyethylene (UHMW-PE) and derivatives thereof, such as HSHM-PE, comprising a step of immersing the elements (10) in a liquid colourant (1) comprising at least: water (2); pigments (3) chosen from anthraquinone colorants, azo colorants and inks for the textile industry; and additives (4) comprising at least an equalizing agent (6) and a dispersing agent (7); the immersion step being performed at a temperature between 500C and 2200C.
La présente invention concerne un traitement pour colorer des éléments à base de matière polymère, en particulier des fils produits sélectivement en polyéthylène (PE), en polyéthylène de très haut poids moléculaire (UHMW-PE), et leurs dérivés tels que le polyéthylène haut module et haute résistance (HSHM-PE). Ce traitement consiste à immerger les éléments (10) dans un colorant liquide (1) comprenant au moins de l'eau (2), des pigments (3) choisis parmi les colorants anthraquinoniques, les colorants azo, et les encres pour l'industrie textile, et des additifs (4) comprenant au moins un agent d'égalisation (6) et un agent dispersant (7), l'opération d'immersion s'effectuant à une température comprise entre 500°C et 2200°C.
