A dark-colored and infrared-reflective fiber without metal composition, a manufacturing method thereof, and a dark-colored and infrared-reflective textile are provided. The dark-colored and infrared-reflective fiber includes a polymer resin material and an organic azo pigment. The organic azo pigment is dispersed in the polymer resin material in the form of a plurality of micro particles. The organic azo pigment has an average particle size between 0.2 micrometers and 4 micrometers and a heat-resistant temperature of not less than 300 C. The organic azo pigment has an infrared reflectance of not less than 50% in an infrared wavelength range between 780 nm and 2,500 nm.
