New printing effects on cotton/polyester blended fabrics were achieved by printing the fabrics using a printing paste containing different concentrations of sodium hydroxide, and then steamed applying different steaming time and temperatures, in order to improve the two fabrics physical properties. These changes resemble in: Decreasing fabric weight, increasing water absorbency and air permeability, shrinkage effect which cause the differential crimping effect and color tones. Factors affecting these new effects were studied and discussed in details to determine the most desirable appearance of cotton / polyester blended fabric.
