PURPOSE:To obtain a deeply colored part having excellent deep color properties and clarity by treating a dyed material of fiber product with a well-known fluorine-based polymer and a fluorine-based polymer containing a perfluoro group and a hydrophilic group. CONSTITUTION:A dyed material of fiber product is immersed in a treating solution comprising a well-known perfluoroalkyl group-containing fluorine-based polymer and a fluorine-based polymer containing a perfluoroalkyl group and a hydrophilic group [(poly)alkylene oxide unit, carboxyl group, etc.], treated, predried and then dried to inexpensively give a fiber product having excellent durability and high-degree deep color properties. |
