How do I wash the sheets that turn yellow after being used for a long time? 

If the yellowing is caused by exposure to the sun or high temperature after washing, it cannot be recovered. It is recommended not to put the clothes in the sun or near high temperature; there may be residues from washing products or stains such as sweat that have not been cleaned in the air. It is oxidized and yellowed, and moisture causes yellowing.
