What are the differences between synthetic and natural fabric dyes in longevity?

The longevity of fabric dyes depends on whether they are synthetic or natural. Synthetic dyes, made from petroleum-based chemicals, are known for their vibrant colors and high resistance to fading. They bond strongly with fibers, ensuring long-lasting results even after repeated washing and exposure to sunlight. However, they may degrade over time due to harsh detergents or environmental factors.

Natural dyes, derived from plants, minerals, or insects, offer eco-friendly alternatives but generally have shorter lifespans. They fade faster when exposed to sunlight, water, or washing. While some natural dyes can be mordant-treated to improve longevity, they still tend to lose vibrancy quicker than synthetic options.

In summary, synthetic dyes outperform natural dyes in longevity, but natural dyes provide sustainability benefits. The choice depends on priorities—durability or environmental impact.
