To obtain a pile sheet having excellent set stability in working, capable of performing a formation following to a complex solid curved face and having excellent decorativeness or beautifulness by forming a ground fabric for a pile by using specific polyester fibers having structural characteristic values of high amorphous density and low amorphous orientation.
This pile ground fabric is obtained by using a polyester fiber yarn having specific structural characteristics that are a high amorphous density of 1.30-1.37 g/cm2 and low amorphous orientation of 0.088-0.45 and having 30-200 kgf/mm2 apparent Young's modulus, 0.2-1 g/d initial stress, 3-10% initial elongation and more than 100% breaking elongation, or using a complex structural yarn comprising the polyester fibers as a core yarn and covering with the other fibers as a sheath yarn.
