Process for producing oriented thermoplastic polyester resin sheet, and laminate-molded body

A process for producing an oriented thermoplastic polyester resin sheet, which comprises:

• pultrusion-drawing a thermoplastic polyester resin sheet in an amorphous state at a temperature from the glass transition temperature of the thermoplastic polyester resin −20° C. to the glass transition temperature of the thermoplastic polyester resin +20° C.;
• and then drawing the resultant uniaxially at a temperature higher than the temperature for the pultrusion-drawing and at a temperature from the rise-up temperature of the crystallization peak of the thermoplastic polyester resin in its differential scanning calorie curve measured at a temperature-raising rate of 10° C./min. to the rise-up temperature of the melting peak thereof in the curve, wherein
• the pultrusion-drawing is a drawing process involving pultrusion-drawing the thermoplastic polyester resin sheet between a pair of rolls having a clearance narrower than the thickness of the thermoplastic polyester resin sheet, heated to a temperature from the glass transition temperature of the thermoplastic polyester resin −20° C. to the glass transition temperature of the thermoplastic polyester resin +20° C., and rotated in the direction of pulling at a speed equal to or slower than the sheet-feeding speed when the thermoplastic polyester resin sheet is pulled at a pulling speed under the same condition in a state where the rolls are not rotated.
