A novel strategy was introduced using plasma-assisted screen-printing with rare-earth doped strontium aluminate nanoparticles to produce photoluminescent nonwoven polypropylene fabrics. Superhydrophobic properties of the phosphor-printed nonwoven polypropylene textiles were enhanced by increasing the phosphor ratio in the printing paste.
Polypropylene fibers have been applied in various fields, such as automotives, plastic furniture, medical devices, and food packaging. Polypropylene fibers are characterized by low-cost, high flexural and impact strength, as well as high resistant to chemicals, mois-ture, fade, electricity and fatigue. However, polypropylene fiber is inherently resistant to stain because they have no active dyeing sites on their surface. Therefore, it has been impossible to dye polypropylene fibers after extrusion. In the current study, we introduce a novel strategy toward the production of photoluminescent nonwoven polypropylene fab-rics by plasma-assisted screen-printing with rare-earth doped strontium aluminate nanoparticles. Aqueous-based phosphor-binder printing paste was applied directly onto nonwoven polypropylene textiles. The superhydrophobic properties of the phosphor -printed nonwoven polypropylene textile substrates were enhanced with increasing the phosphor ratio in the printing paste. Both of ultraviolet protection and antibacterial activity of the phosphor-printed nonwoven polypropylene fabrics were also considered. The pro-duced colorless photoluminescent layer displayed an emission band at 515 nm after being excited at 371 nm. The phosphor-printed fabrics exhibited various colorimetric shades, including off-white beneath daylight and green beneath ultraviolet lamp, as proved by photoluminescence spectra and CIE Lab properties. The comfortability was inspected by testing both of air-permeability and bend length to indicate good flexibility and breath -ability. The phosphor nanoparticles were studied for their morphological properties to
