PURPOSE: Provided is a method for surface treatment of a swimming cap by forming a pattern on the interior and the exterior surface of a swimming cap obtained by synthesizing silicon and bioceramic as a main component, and performing corrosion treatment. Therefore, the cap has excellent wearing property and design. CONSTITUTION: In a swimming cap obtained by synthesizing silicon and bioceramic, the surface treatment method comprises the steps of: forming various patterns on the interior and the exterior surface of a swimming cap by performing laser processing; developing the pattern-formed surface using a developing solution such as 0.5% sodium carbonate aqueous solution; washing the surface with water; and forming a pattern by performing corrosion treatment with a corrosion solution such as 5% hydrochloric acid.
