    Polypropylene textiles have been used in the development of various industrial products, such as automotives, plastic furniture, and medical tools. However, polypropylene resists dyeing due to a deficiency of active staining spots. Here, we developed a new strategy towards new afterglow and photochromic fibres from recycled polypropylene plastics using plasma-supported coloration with rare-earth activated aluminate nanoparticles (REANPs). Plasma curing was used to generate active dyeing sites on the polypropylene surface. A thin film of REANPs (2-10 nm) was deposited onto the plasma-pretreated polypropylene surface. Various analytical techniques were applied to inspect the morphology of the REANP-finished polypropylene fibres. The polypropylene dyeing activity was much improved after being exposed to plasma. Both photoluminescence analysis and Commission internationale de l'éclairage (CIE) laboratory coordinates proved that the polypropylene fibres exhibited a white colour in daylight and green in ultraviolet light. The thin afterglow layer immobilized onto the polypropylene surface exhibited an emission band of 524 nm upon excitation at 365 nm. The sliding angles dropped from 12° to 9°, but the contacting angles increased from 139.4° to 145.0° when the REANP ratio was raised. These findings show that REANP-finished polypropylene had good colourfastness, antimicrobial activity, and ultraviolet light blocking. Both stiffness and permeability to air of REANP-finished polypropylene were explored to designate excellent comfort characteristics. © 2023 John Wiley & Sons, Ltd.
