"Greying occurs due to damaging of the fabric and more importantly by soil re-deposition in the wash. The soil which re-deposits mostly contains of environmental soils, like soot in the air, household dust, sebum from skin etc. Another important part consists of stains (removed) from clothing in the wash."

"Greying is caused by dye transfer or redeposition of soil or fugitive dyes."
