Fiber coating method

A fabric coating method comprising:

• 1) A calcined mineral particle preparation step of preparing calcined mineral particles by preparing macsumsuk or clay minerals, pulverizing the macsumsuk or clay minerals to a size of 0.1 to 5 mm, and calcining the pulverized macsumsuk or clay minerals at a temperature of 800 to 1,100° C.;
• 2) A mixing step of producing a mixture by preparing zirconia silicate (ZrSiO3), nano silver, and yucca extracts and mixing the zirconia silicate (ZrSiO3), the nano silver, and the yucca extracts with the calcined mineral particles;
• 3) A wet pulverization step of producing a slurry by adding water to the mixture and then performing wet mixed pulverizing with a ball mill;
• 4) a granule production step of producing granules by processing the slurry by a spray drying method with a granulator;
• 5) a dry pulverization step of producing granular powder by dry-pulverizing the produced granules to a size of 0.1 to 50 μm;
• 6) a coating step of mixing the granular powder with a urethane-based solvent and coating a fabric;
• 7) a surface treatment step of treating a surface by causing a surface of the coated fabric to pass through a gravure roller;
• and
• 8) a laminating step of laminating thermoplastic polyurethane (TPU) to adhere to the surface of the fabric to which the surface treatment is completed.
