Abstract
The present invention relates to a manufacturing method of a unique textured yarn by upgrading the equipment and processing the modified single-material precursor, the textured yarn thereof, and the fabric made with the textured yarn thereof. According to the method, titanium dioxide is added into a precursor of PET pre-oriented yarn with single filament DPF<0.5 to form the first precursor. Then, the first precursor is fed into a flat conveying roller, and then into a differential roller, and then into an accelerating roller to form a dark and light double colored textured yarn with linen-like appearance and tone. Then, the dark and light double colored textured yarn is conveyed to a heater for heating and setting, and then conveyed to a false twisting machine for processing. Finally, it is conveyed to a nozzle for spraying.
