Colour Fastness to Chlorinated Water Explained: How It Works in Performance Sportswear
Colour Fastness to Chlorinated Water is best understood as stability in pool water. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
stability in pool water, which is why the value appears on almost every technical data sheet. Working figures for Colour Fastness to Chlorinated Water normally sit around grade 4 at 1 ppm chlorine in mainstream production. Note ISO 105-E03 chlorinated water on the tech pack so nobody tests against an older revision.
Why it matters in practice
it is mandatory for swimwear, so it influences buying decisions more than most buyers expect. Record elastane content alongside Colour Fastness to Chlorinated Water, because blends shift the measured value. A result outside grade 4 at 1 ppm chlorine usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
grade 4 at 1 ppm chlorine. Ranges vary by construction, so compare like with like. Keeping reference values for Colour Fastness to Chlorinated Water lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 105-E03 chlorinated water, since both affect the reading.
How it is measured
ISO 105-E03 chlorinated water is the reference normally quoted on a test report. Working figures for Colour Fastness to Chlorinated Water normally sit around grade 4 at 1 ppm chlorine in mainstream production. Note ISO 105-E03 chlorinated water on the tech pack so nobody tests against an older revision.
Frequent mistakes
Comparing results from different standards, testing unwashed fabric, and writing the target without tolerance are the common errors. Record elastane content alongside Colour Fastness to Chlorinated Water, because blends shift the measured value. A result outside grade 4 at 1 ppm chlorine usually points to process drift rather than to the fibre itself.
