With the increasing awareness of synthetic
dyes' health and environmental hazards, the coloring
agents are manufactured using natural products due to
their biodegradability, and high environmental
compatibility is widespread nowadays. This study dyed
cotton fabrics with the natural color extracted from
Malabar spinach (Basellaalba) leaves. The colorant was
extracted from the leaves using an aqueous extraction
technique, and the cotton fabric was dyed in two
processes by only the pure coloring extraction and
added NaCl as a fixation agent to increase the fixation
rate of natural dyes. Finally, dyed fabrics have been
subjected to different textile laboratory tests, e.g., color
absorbance %, tensile strength, tear strength, water
fastness, wash fastness, perspiration fastness, and
rubbing fastness (dry and wet). Considering the results,
dyeing with purely natural dyes without any fixation
agent could be an effective process for cotton dyeing.
