Claim: Kotex were first manufactured as bandages during World War I.
Origins: Though no soldiers were charging about the battlefield with sanitary napkins tied to their arms, a new type of material which had proved so effective as bandages in that conflict was years later revamped into Kotex.

Five times as absorbent as cotton and costing only half as much, Cellucotton was used to bandage wounds in World War I.
