Effects of extra washing after treatments on fastness and spectrophotometric properties of dyed PET/viscose/elastane fabric

Extra washing treatments are one of the effective ways to overcome problems like poor fastness, and called reproduction process in textile finishing operation. In this experimental study, we investigated some extra washing aftertreatments as reproduction for completely deep dyed PET/viscose/elastane woven fabric using reductive and reactive washing methods. After washing applications, we measured the colour performances (?E, ?L, ?C, ?H) and colour fastness properties (colour fastness to washing, perspiration, rubbing, water, and dry cleaning) of washed samples by comparing according to the reference sample. The results of experimental studies showed that we could achieve fastness values of samples up to an optimum value without changing their colorimetric values
