A method for preparing an aluminosilicate structure body having a basic framework structure of the following Chemical Formula 1, an X-ray diffraction pattern comprising lattice spacings shown in the following Table 1, and a skein-shaped morphology on a surface layer, the method comprising:

• preparing a reaction mother solution having a viscosity of 3.1 to 7.1 mPas by adding an aqueous sodium silicate solution prepared by reacting an aqueous sodium hydroxide solution and a silica source to an aqueous sodium aluminate solution prepared by reacting an aqueous sodium hydroxide solution and an alumina source, and stirring the resulting mixture (S10);
• preparing a synthetic mixture by adding a seed to the reaction mother solution and aging the resulting mixture under stirring (S20);
• and
• preparing an aluminosilicate structure body having a novel crystal structure and the skein-shaped morphology by hydrothermally treating the synthetic mixture (S30):
