According to the invention, a chemically adsorbed film is formed on an apparel material which has a surface layer containing fluorocarbon groups and a stem which is chemically bonded by --Si-- bonds to the material. A high performance apparel material thus can be provided which retains intrinsic properties of material such as ventilation and aesthetic appearance and is excellently durable and highly water- and oil-repelling and anti-contaminating or excellently durable and highly hydrophilic. The chemically adsorbed film has a very thin surface layer containing fluorocarbon groups, and is thus excellently water- and oil-repelling and anti-contaminating. In addition, since its stem is chemically bonded via --Si-- bonds to the material, it does not separate and is excellently durable. Further, it is very thin and does not adversely effect intrinsic properties of material such as ventilation, color and aesthetic appearance.
An apparel product comprising a chemically adsorbed monomolecular film comprising molecules having stem groups bonded by covalent bonds to a surface of the apparel product, wherein said covalent bonds comprise --Si-- atoms.
An apparel product comprising a siloxane-based monomolecular inner layer film formed on a surface of the apparel product and a chemically adsorbed monomolecular film comprising molecules having stem groups bonded by covalent bonds comprising Si atoms to the inner layer film.
