SHEET HAVING HIGH PREVENTING EFFECT ON STAIN ADHESION AND COATED WITH SILICONE-BASED COMPOUND AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a sheet to which a protein-containing stain is hardly stuck. SOLUTION: A substrate sheet is coated with a first silicone-based compound having <=30.0 mN/m surface tension at the side of the substrate sheet and a second silicone-based compound having a surface tension lower than that of the first silicone compound is positioned at the surface side. A sheet having the surface coated with a silicone has high water repellency and a protein- containing stain is hardly stuck to the surface of the sheet. Since the sheet has high resistance to friction, the effect is durable.
