The present invention relates to a device for heat-treating an inner surface of a braid for reinforcing a hollow fiber membrane for water treatment, and more particularly, to a device for heat-treating an inner surface of a braid for reinforcing a hollow fiber membrane for water treatment with a temperature control structure, in which by enlarging the inner diameter of the braid while increasing a density of a fiber texture forming the inner surface of the braid, improving a roundness of inner and outer diameters, and increasing a pressure resistant strength, it is possible to obtain effects of improving physical properties of a hollow fiber enforcement membrane as well as enhancing filtration reliability and water permeability, and increasing a service life and reducing, and protect a worker from a safety accident such as burns at the time of an operation such as a replacement of the knitted yarn.
