The invention discloses a preparation method of an anti-scald textile. The preparation method is characterized by comprising the following step of: in a solvent, under the oxygen free condition and the protection of inert gases, irradiating a textile and a graft monomer to enable the textile and the graft monomer to carry out co-irradiation grafting reaction, thus obtaining the anti-scald textile, wherein the graft monomer is a compound with thermo-sensitivity, and the hydrophilicity of the graft monomer can be converted to hydrophobicity at the temperature above 32 DEG C. The invention also discloses an anti-scald textile prepared by the method. The preparation method and the anti-scald textile have the following effects: the preparation method is easy and convenient to operate; the durability of the textile in an anti-scald effect is greatly increased; the use thickness of the anti-scald textile is simultaneously reduced to a lower level; the anti-scald textile disclosed by the invention can realize the anti-scald effect on the premise of retaining inherent skin friendliness and water permeability; and the anti-scald textile can maintain a good anti-scald effect after being used repeatedly.
