One of the most important drawbacks for the international marketing is the
lack of color homogeneity of some cotton fabrics. The main target of this work is to
study the effect of change in color strength KlS and mechanical properties using
different leveling agents before and after dyeing for cotton fiber (Giza 8S,Giza 86,and
Giza 70) to achieve the optimum way and economical cost of dyeing that gives the
equivalent values of KlS for the different cotton cultivars or decrease the differences
between the values of KlS for the dyed cotton cultivars .It was found that Giza 70
resulted a higher strength followed by Giza 86 and finally Giza 85 ,where as the
elongation property is following the strength but in the negative way .While for the
KlS value Giza 86 recorded the highest value and then Giza 85 and the last was Giza
70.
