MADEN ATIKLARININ SÜRDÜRÜLEBİLİR MANYETİK PİGMENT OLARAK TEKSTİL SEKTÖRÜNE GERİ KAZANIMI

With the increasing number of consumers of the Textile Industry day by day, one of the biggest causes of the environmental damage it creates is synthetic dyes. The use of natural pigments as an alternative to these dyes will be important for both human health and environmental use. In this study as an alternative to synthetic dyes, iron oxides with various colors and magnetic effects were investigated. In order to increase their stability, composite structures were prepared by adding 3% clay (sepiolite and halloysite) to the in-situ synthesis solution medium. Magnetic sensitivity was sought in these structures to be suitable for digital printing. It has been observed that the magnetic properties of halloysite decreased however no such behavior was found in sepiolite-based structures. The colors obtained from the pigments were subjected to RGB (Red Green Blue) color variability tests and experimentally converted into hexadecimal form. While it was observed that the magnetic properties of the Halloysite-added samples slightly decreased, the Sepiolite samples preserved their magnetic properties. The colors obtained from the pigments were subjected to RGB (Red Green Blue) color variability tests, and when the color values were converted into hexadecimal form, it was observed that the color of the pigments from reddish earth tone to dark black became deeper. In the color chart, the reddest color # 4a0f07, the lightest yellow # 783c00, and the blackest color # 1b100c were halloysite, sepiolite, and clay-free, respectively. Thus, in the production of pigments with different colors and magnetic properties, it has been seen that abandoned and environmentally damaging mine wastes can be used as a secondary source.
