Apparatus for manufacturing textile grid with increased adhesion and method thereof

An apparatus for manufacturing a textile grid with increased adhesion for building, repairing, or reinforcing a concrete structure, the apparatus comprising:

• a fabric yarn supplying unit that supplies textile grid fabric yarn in a form of a bundle of yam;
• a weaving-knitting machine that forms a woven-knitted textile grid in a lattice form through a manner in which the fabric yarn is woven and knitted so that wefts and warps cross to be coupled to each other;
• a resin impregnation tank that impregnates the woven-knitted textile grid with a resin to form a resin impregnated textile grid;
• a coating chamber that comprises a first coating material spraying nozzle and a second coating material spraying nozzle installed in the coating chamber, configured for coating an abrasive material powder that is a surface coating material onto a surface of the resin impregnated textile grid and which forms a coated textile grid before the resin impregnated textile grid is cured;
• a camera that is installed at a rear end of the coating chamber and captures a coating-image to inspect a coating state of the coated textile grid;
• and
• a controlling device that adjusts a spraying amount of the surface coating material according to the coating-image captured by the camera,
• wherein adhesion of the textile grid to a concrete structure is increased by the abrasive material powder that is the surface coating material.
