Production of POSS nanoparticle containing polypropylene fibres dyeable with acid and basic dyes
Acid and basic dyeable polypropylene (PP) fibres have been produced with the inclusion of polyhedral oligomeric silsesquioxane (POSS) nanoparticles via melt spinning technique. Octa ammonium POSS (OA-POSS) and tris sulfonic acid ethyl POSS (SA-POSS) have been used for the modification of PP fibre. The tensile, thermal and morphological properties of the fibre samples are characterized by tensile testing, differential scanning calorimeter and scanning electron microscopy respectively. The effects of dye concentration, dyeing temperature and time are investigated on the dyeability properties of the fibre samples. The wash fastness of fibre samples is also studied. It is observed that the addition of OA-POSS and SA-POSS increases the dyeability of PP fibre with appreciable mechanical properties. Both POSS nanoparticles increase the dyeability of PP fibre by increasing ion-ion interaction.
