An experimental study on production of intelligent textile by using ionocromic materials
Abstract
The production of an intelligent textile material that changes color under the influence of pHwas researched in this research article. For this purpose, halochromic dyes were used. Inhalochromic dyes, bleeding and fastness problems are encountered after dyeing. In order tosolve these problems; the dye is fixed with cationic fixators in the textile fiber. In this study, awoven nylon fabric was dyed with Alizarin Red S halochromic dyestuff by conventionaldyeing method which was followed by post-treated by tannic acid/potassium antimonytartarate at different ratios (1%, 2%, 3%). After dyeing and post-treating, CIELab, K/S, ?E*values were measured by spectrophotometer and compared. In order to investigate the effectof halochromics on the post-treated, dyed and post-treated fabrics were immersed in 5different solutions prepared by using HCl and NaOH between pH 2 and 10, and the sampleswere removed after 1 hour and the color change in the samples was compared. After theprocess, the speed of fixation of the dye molecule onto the fiber was increased.
