Influence of dendrimer finishing on color assessment of CO/PES blended fabrics

This research focuses on the assessment of color modifications occurring on the dyed cotton/polyester blended fabrics due to the nanoparticle sized dendrimer, dendrimerfluorocarbon and fluorocarbon finishing which can substantially alter surface properties. Thanks to the nanoparticle size, the fabric surface area is increased improving the interaction with the matrix polymer. By this way highest performances are achieved in some typical textile finishing applications. A remarkable influence of finishing onto reflectance and color difference of fabrics were observed. In fact, roughness influences the surface reflectance, as it increases the scattering of light thus decreasing surface reflectance. Particle sizes of chemicals designate the distribution and orientation of surface roughness and in addition the overlay of their absorbance values in the short wavelength results in color differences.
