The present invention relates to a process for manufacturing yarns with photoluminescence properties based on polymeric composites. Said process consists of several stages, wherein an initial polyethylene terephthalate (PET) concentrate is produced, using the ultrasound-assisted extrusion process, with a perylene concentration and/or Zinc oxide nanoparticles of up 1% by weight. Subsequently, this composite is diluted to concentrations between 0.1% and 0.001% by weight of perylene/Zinc oxide nanoparticles. Said dilutions are fed to a spinneret where the mono-component and bi-component filaments or yarns of the shell core type are manufactured. In this way, the filaments obtained exhibit a photoluminescence with ultraviolet (UV) light. Additionally, these filaments are used to produce embroidery and fabrics. The present invention is directed to the textile industrial sector, for the manufacture of yarns, fabrics, clothes for industrial safety, military or official uniforms and sportswea r, among others. En la presente invención se protege un proceso para la fabricación hilos con propiedades de fotoluminiscencia a base de compuestos poliméricos, este proceso consta de varias etapas, en donde inicialmente se produce un concentrado de polietilentereftalato (PET), empleando el proceso de extrusión asistida por ultrasonido, con una concentración de perileno y/o nanopartículas de óxido de Zinc del 1% en peso; posteriormente este compuesto se diluye a concentraciones entre 0.1 a 0.001 % en peso de perileno/ nanopartículas de óxido de Zinc. Estas diluciones se alimentan a una hiladora en donde se fabrican los filamentos o hilos monocomponentes y bicomponentes del tipo núcleo coraza. De esta forma se obtiene filamentos que presentan una fotoluminiscencia con la luz ultravioleta (UV); además, estos filamentos se utilizan para producir bordados y telas. La presente invención esta dirigida al sector industrial textil, para la confección de hilos, telas, ropa para seguridad industrial, uniformes militares u oficiales y ropa deportiva, entre otros.
