Method for controlling clothing treatment apparatus

A method for controlling a laundry treating apparatus including a tub where water is stored, a drum rotatably disposed inside the tub to provide a space where laundry is accommodated, a water supply configured to supply water to the tub, and a drainage configured to discharge water from the tub, the method comprising:

• a first sensing step of sensing an amount of laundry by rotating the drum;
• a water supply step of supplying water to the tub up to a preset reference water level for each amount of laundry;
• a foreign substance removing step of rubbing the laundry with water by rotating the drum;
• a drainage step of draining water stored in the tub;
• a second sensing step of sensing an amount of laundry stored in the drum after the drainage step;
• a dehydration step of removing water from the laundry by rotating the drum;
• a third sensing step of sensing an amount of laundry stored in the drum after the dehydration step;
• a first determination step of determining a material of the laundry based on a thickness via a difference between the amount of laundry measured in the second sensing step and the amount of laundry measured in the first sensing step;
• and
• a second determination step of determining a material of the laundry based on a moisture content via a difference between the amount of laundry measured in the third sensing step and the amount of laundry measured in the first sensing step.
