In this work acrylic/ wool fabrics is printed with one dye (Reactive dyes) in one step as an easy method. The main aim of this study is increasing the printability of acrylic fabrics towards reactive dyes which are not usually used for acrylic coloration, by using commonly available finishing agent, N-methyloldihydroxyethyleneurea (N-MDHEU), which increase the catholicity of the acrylic fabrics surface enhancing the electrostatic attraction between the negatively charged dye molecules and protonated carbonium group of N-MDHEU. Different factors that may affect the printability of blended fabrics will be studied with respect to color strength and fastness properties. The results of the experimental work offer a new viable method for applying one class of dyes (reactive dyes) on the acrylic/ wool blended fabrics. It was found that addition of (N-MDHEU) in printing past gave good printability with reactive dyes .The effects of the addition of (N-MDHEU) in printing past are characterized by infrared spectroscopic.
