PURPOSE: To obtain the subject fabric capable of easily presenting a three- dimensional body having a complicated surface by heat forming, having good quality in appearance and being easily produced and suitable for automobile interiors, etc., by constituting the fabric with a low oriented undrawn thread having a specific physical properties. CONSTITUTION: This fabric for molding is obtained by using a polyester filament yarn which is a low oriented and partly undrawn filament yarn mainly comprising an ethylene terephthalate unit having >=10 undrawn parts/m in the longitudinal direction of the polyester filament, 0-0.3 structure integrating parameterε0.2 and 1.365 g/cm<3> average density. The undrawn parts in the longitudinal direction of the filament yarn is preferably expressed by installing a pin between rollers and drawing at a low magnification. The structure integrating parameter is brought into the said range by preferably spinning the said thread in a high speed of 2,000-4,000 m/min.
