Young coconut fiber, which is often overlooked as waste, has great potential as a source of natural dyes that can be used for dyeing silk threads, thus creating new opportunities in the environmentally friendly and sustainable textile industry. Young coconut fiber is rich in active compounds such as saponins, phenols, and tannins which function as effective color carriers. The use of young coconut fiber as a natural dye not only provides added value to agricultural waste, but also supports the concept of a circular economy in the textile industry. This research is an experimental study that aims to examine the dyeing effect on silk yarn using young coconut husk extract with nanobubble water solvent. The study involved several stages, including extraction, dye application, fixation, and sample testing. The results showed that dyeing silk yarn with coir extract and nanobubble water, combined with fixation agents such as ferro sulfat, alum, and lime, produced brownish green, beige, and brown colors. In terms of tensile strength, pure silk yarns scored 8.7%, while yarns dyed with nanobubble water and fixation agents had tensile strengths ranging from 7.4% to 12.1%, with samples fixed using alum showing the highest strength. The creep test showed values between 10.1% and 12.3%, with the natural silk yarn reaching 10.8%. The colorfastness test on dyed yarns showed good results, with values between 2 and 5 depending on the fixation material used. These results demonstrate the effectiveness of young coconut husk extract as a sustainable natural dye for silk yarns. © 2025 Malque Publishing. All rights reserved.
