Abstract
In this study, the print quality of lines were investigated in warp and weft directions that were inkjet printed on various weave structures of polyester such as plain, 2/2 twill, 3/1 twill, 3/2 twill and 4/1 twill. In order to study the effect of weave structure on the quality of inkjet printing on polyester fabrics, lines having a width of 1 mm, 2 mm, and 4 mm were inkjet-printed and the print quality was measured as the line width. The quantitative analysis of lines width was performed by scanning the fabrics with a scanner. The obtained result showed that the weave structure is effective on the lines width and print quality, and the plain weave structure had the worst print quality in both directions. Also, the width of lines printed in the weft direction was more than lines printed in the warp direction which is possibly due to more density of warp than weft. The effect of weave structure and print direction on lines width and print quality was also confirmed by the analysis of variance (ANOVA) results. The image processing was shown that the ink spreading shape on the various fabrics is different and is affected by the weave structure and the print direction.
