El objetivo de este trabajo fue obtener el efecto del pretratamiento de tejido de algodón standard EMPA mediante radiaciones UV-C, con objeto de obtener su comportamiento diferenciado respecto al tejido sin tratar, frente a la redeposición de impurezas y la detergencia con impurezas liquidas y sólidas. Las formulaciones detergentes se planificaron con mezclas de tensioactivos, tales como el tensioactivo aniónico, dodecilbencenosulfonato sódico (SDBS) y un tensioactivo no-iónico alcohol graso etoxilado (AE) con 7 moles de O.E, por separado y en mezcla de ambos en varias proporciones. Las impurezas utilizadas para la evaluación de la detergencia fueron de tipo oleoso, ácido oleico y de tipo sólido negro de humo. Las redeposiciones de impurezas se estudiaron empleando el negro de humo durante el lavado. Con objeto de justificar los cambios superficiales del tejido de algodón con pretratamiento con UV-C. se determinaron capilaridades y se justificó el cambio químico superficial del algodón mediante su correspondiente espectro de infrarrojos.(FTIR) The aim of this work was to study the effect of treatment of EMPA standard cotton fabric with UV-C radiation to determine the performance of detergency with treated and untreated fabric, as well as redeposition of impurities after washing those fabrics. The detergent formulations used for testing were an anionic surfactant, sodium dodecylbenzenesulfonate (SDBS), and a non-ionic surfactant, alcohol ethoxylate (AE-7) with 7 m. EO, separately and in mixtures of the two in varying molar ratios. The impurities used for evaluation of detergency were oleic acid as an oily impurity and carbon black as a solid impurity. Redeposition of the solid impurity was studied using carbon black in the wash. Differences in capillarity for water absorption by the cotton fabric and superficial chemical changes on the surface of the fabric were determined using the corresponding FTIR infrared spectrum
