Bagging behavior of cellulose fabrics printed with madder natural dye and sodium alginate thickener

Used synthetic dyes and concentrators in printing are generally oil-based, but them effluent is toxic and dangerous, which can be harmful to human health and the environment. Therefore, use of natural dyes and concentrators in printing has received attention as an appropriate alternative. In this research, cotton and viscose samples were printed with madder dye and sodium alginate as concentrator. Then, the effect of printing on color, physical and bagging behavior of cotton and viscose fabrics was evaluated. The results showed that printing on the fabric causes a faster water drop absorption time, reduction of the wrinkle angle and improvement of bagging behavior of cotton and viscose specimens. Also in the same conditions, the magnitude of bagging in cotton fabric is higher than viscose. . In general, the results of this study showed that concentrators and natural colors can be used in printing and achieve high fastness and good properties of the fabric
