Abstract
A fiber comprising a vinyl alcohol units-containing polymer, said polymer being modified at the oxygen atoms of its alcoholic hydroxyl groups with a group represented by the following formula I ##STR1## wherein M represents a chelate-forming metal atom and R represents an alkyl group. The fiber has excellent resistance to hot water and wet heat and does not stick, adhere or shrink even when dyed at high temperatures or treated by steam ironing, thus proving to be of markedly high commercial value.
