The color is the one of the most important factor at textile and it is also an importantfactor at the point of purchasing a garment. Effect pigments provide extra color effects;they give angular color dependence such as iridescence, color travel, and luster. Thesespecial pigments can be found in a variety of industrial products and end-userapplications for instance in automotive, fashion, cosmetic and decorative texture whichmake special effect like angle-dependent color. In this work, we studied six differentkinds of effect pigments and applied them on polyamide fabrics. Then the CIExy andCIEL*a*b* diagrams of all samples plotted in five different angles; and the color offabrics, printed by these pigments, studied base on CIE diagrams. On the other hand, thecolor of samples asked from randomly chosen people and compared with color whichpredicted from CIE diagram. In addition ΔE values between fabrics, printed by effectpigments, and unprinted fabrics calculated and compared. Finally the reproducibilityproperty in the printing process has been considered.The results of this thesis work show that the color which we expected from fabric, printedby effect pigments, are different with human visualization. / Program: Magisterutbildning i textilteknologi
