Sustainable and Mass Production of Cotton Dyeing with Natural Dye (Weld) in the Textile Industry

The use of natural dyes in textile fibers goes back an ancient times. These dyes have been used in traditional methods until now. The use of natural dyes has come to importance in the textile industry in recent years. This situation desired sustainable, mass, and large-scale productions by the textile industries. Many dye plants used in natural dyeing have been very successful in laboratory studies. However, there are significant problems in using these dyeings in industrial-scale production, and they cannot be applied on an industrial scale in a sustainable way. In this work, weld dyeing recipes were created on industrial scale samples by the jet dyeing machines. Color change, washing, perspiration, rubbing fastness 4-5, and lightfastness found 3-4. The optimum conditions were determined for dyeing by the dyeing machine. According to the optimum dyeing recipe, cotton fabric was dyed with weld by the large-scale dyeing machine. The main coloring compounds are luteolin and apigenin in the weld. The main coloring compounds (luteolin and apigenin), mordant metal (aluminum), fastness tests, color coordinates, and fastness values were investigated in the dyed fabrics by different methods.

Automated summary

The use of natural dyes in textile fibers has a long history and has gained importance in the textile industry in recent years. Despite successful laboratory studies, there are challenges in applying natural dyes in industrial-scale production sustainably. This study focused on creating weld dyeing recipes for large-scale production and investigating the main coloring compounds, mordants, and fastness values in dyed fabrics.
