A coated fiber structure having a high abrasion, flexural fatigue, and flame stardant resistance comprises a number of individual fibers having a thermal decomposition point of 230° C. or more, and coating layers covering and fixed to the surfaces of the individual fibers at a surface covering percentage of 35% or more and comprising a fluorine-containing polymer in the form of individual particles provided by heat-treating the polymer on the individual fibers at a temperature of from 60° C. below to 60° C. above the melting point of the polymer. |
