  Abstract

In textile dyeing, natural dyes and plant-based biomordants align well with the growing emphasis on sustainability in the industry. Using anthocyanin from Dendrobium sonia “Ersakul” (DS) orchids as a natural pigment is an innovative approach, offering a sustainable supply of color. Anthocyanins are biodegradable and sourced from renewable plant materials, making them a green alternative to synthetic dyes. Using blooms from orchids like Dendrobium sonia, which might otherwise go to waste, adds economic value to by-products in horticulture or floriculture. Testing the effectiveness of metallic mordants and biomordants derived from Senna auriculata (SA) bark is a great way to compare the environmental and practical benefits of biomordants over their synthetic counterparts including color fastness and enhancement. The study highlights an excellent application of plant-based materials as sustainable alternatives in textile dyeing. The dual functionality of Senna auriculata bark extracts as biomordants and as agents with antibacterial properties adds immense value to sustainable textile applications. Fourier-transform infrared spectroscopy (FT-IR) results validate the successful bonding of the dye to the cotton fibers, supported by functional groups in the dye interacting with the fiber structure. Field Emission scanning electron microscopy (FE-SEM) ensures that the dyeing process preserves the cotton’s quality, maintaining its strength and usability. The color parameters (L*, a*, b*) for dyed cotton fabric were analyzed with an X-rite Ci4200UV D65-10 spectrophotometer regarding CIELab values. Color fastness to washing and rubbing was evaluated using digiWASH SS™ and crock meter, respectively, good performance in washing and rubbing fastness tests indicates the dyes’ suitability for clothing and textiles. Overall findings provide sustainable and environmentally friendly textile dyeing process.
