Abstract

Color strength of polyethylene terephthalate (PET) fabrics, which were constructed by microfibers, was can be increased
by various pre and after treatment and also changing the condition of dyeing procedure. Alkali and plasma pretreatment
on micro polyester fabric leave an insignificant effect on spectral reflectance of the treated colored fabric. However, the
liposome dyeing as well as increasing the dyestuff percentage, as a change in dyeing condition, has the highest effects on
increasing color strength. The color strength of liposome dyed sample is 24.62 and that of the sample dyed with 3 %
(owf) dyestuff is 24.08, both were measured at the maximum wavelengths. The sol-gel coating method has the highest
effects on the reflectance spectra of micropolyester fabric which lead to highest Root Mean Square (RMS = 0.052). The
reflectance values of SiO2 coated fabric considerably increased at the middle wavelength of visible spectrum (510 nm up
to 710 nm) and besides, it decreased at short and long wavelengths.
