A polyester textured yarn and a manufacturing method thereof are provided to mix and twist a non-round cross-sectional polyamide oriented yarn and a circular ultra fine polyamide flat yarn by means of the modified polyamide. A non-round cross-sectional POY(A) is supplied by a supply roller(C) and a fine polyamide FDY(B) is supplied by a supply roller(D). The drafting ratio is determined by the difference of speed of the supply rollers and a drafting roller(G). The twisting ratio is the ratio of the rotation speed of a twister for twisting a yarn and that of the drafting roller. The heating temperature means the temperature of the first heater(E). When mixing and drafting two kinds of original yarns, the non-round cross-sectional POY original yarn is used as a core yarn. The general fine FDY original yarn is used as the initial yarn. The ratio of the core yarn and the initial yarn is 20-80 wt%:8-20 wt% in order to maintain entirely the functional property and a sense of touch. The working speed is 100-700m/min, the drafting ratio is 1.1-1.3, the twisting ratio is 1.6-2.0 and the heating temperature is 160-200 degrees.
