The only garment you own that touches your face eight hours a day, unwashed for months.
means A removable fabric sleeve that covers a pillow, protecting it and giving you a washable layer between your skin and the stuffing.
from Straightforward compound: 'pillow,' from Old English pyle (related to Latin pulvinus, a cushion), plus 'case' in its old sense of 'covering or container,' from Old French cas/casse, tracing to Latin capsa, a box. So a pillowcase is literally a 'pillow-box' — a container built to be stripped off and laundered, unlike the pillow itself, which so often isn't.
