Disclosed herein are an apparatus for heat-treating an inner side surface of a braid for a hollow fiber membrane reinforcement for a water treatment and a braid for a hollow fiber membrane reinforcement manufactured using the heat-treatment apparatus, wherein a fiber tissue forming an inner side surface of a braid becomes dense, and the inner diameter of the braid can be expanded, and the circularity of the inner and outer diameters can be accurate, and a compressive strength can be increased, whereby the physical property of a reinforcement membrane of a hollow fiber can be enhanced, and a filtration reliability and water penetration can be improved, thus obtaining an increased service life of a product and an economical saving effect.
