Özet

Polypropylene (PP) fiber dyeable with natural dyes was produced with the inclusion of hyperbranched polymer (HBP) via melt spinning technique. Walnut shell (Juglans regia L), oak gall (Quercus infectoria), dyer's camomile (Anthemis tinctoria), sage tea (Salvia officinalis L) and cehri (Rhamnus petiolaris) are selected as natural dye sources. The effect of HBP concentration on K/S values of natural dyed PP fibers was investigated. The wash fastness and Fourier Transform Infrared (FTIR) spectroscopy results of fiber samples were also studied. Furthermore, the percent crystallinity of fiber samples was determined by differential scanning calorimeter (DSC) and the morphological analyses were performed with scanning electron microscopy (SEM). It was observed that the addition of HBP enhanced the dyeability of PP fiber with walnut shell, oak gall and cehri significantly compared to dyer's camomile and sage dyed ones. The chemical structure of dyes has a great importance in the interaction with HBP. The inclusion of HBP enhanced the dyeability of PP fibers with natural dyes.
