A black tee is rarely just black yarn. It's a black dye applied to a yarn blend — and the chemistry of that blend decides whether your tee stays black or goes grey by wash 12.
Most brands ship the same fade you've come to expect, because solving the fade is expensive at the yarn-sourcing level. The COMF+ standard exists to solve it.
Black should keep depth. If the polyester component fades faster than the cellulosic, the tee is grey to your eye, not to your label.
01Why black tees go grey.
When a blend mixes fibers with different dye affinity — cotton + polyester is the classic offender — the cotton holds black and the polyester slowly fades to grey. After 10 to 15 wash cycles, the polyester component reads lighter than the cotton component. The eye picks this up as dusty black, or faded grey.
This is a fiber chemistry problem. Not a dye-quality problem. No "premium black" claim can fix mismatched dye uptake — it has to be solved at the yarn level.
02The COMF+ blend choice.
70% Modal Rayon — a cellulosic — takes reactive dye consistently. That's the part of the blend doing hand and drape.
30% Recycled Polyester — takes disperse dye — and we tested for dye-affinity match before signing the COMF+ yarn standard. Recycled polyester is harder to dye-match than virgin polyester because yarn lots vary depending on input source. We sample-dye every yard before production.
Most brands skip the sample-dye step because it's expensive and slow. We don't.
03How we test.
The 500-wash protocol is 500 actual machine wash cycles on a fabric panel. Each cycle: cold wash, lay flat dry, photograph against a neutral grey backdrop.
Fade is measured against a delta-E threshold — the color-science measurement of how far the color has shifted. We accept under 2.0 delta-E across 500 washes. A delta-E of 2.0 is the threshold at which most people can perceive a color change in side-by-side comparison.
Nobody else publishes this number because nobody else runs the test. We run it because it's the only way to make the claim honestly.

The color-science measurement of color shift. 2.0 is the threshold at which a side-by-side comparison reads as a color change to the human eye.
04Why no-fade comes with care instructions.
Care matters. Machine wash cold, lay flat or hang dry. Tumble dry strips color from any fabric over time regardless of dye quality.
We do not claim no-fade in hot water with bleach. We claim no-fade in cold-wash, hang-dry care. If you follow the care label, the 500-wash standard holds. If you don't, it doesn't, and no fabric in the world will save you.
Black should keep depth. Here's the math behind why ours does.
