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.

S1 Selection of precursor: Select a precursor of PET pre-oriented yarn (POY) with residual extension difference of 150%160%, NDR (natural draw ratio) of more than 1.4%, and single filament DPF<0.5, modify it by adding 0.8%-1.2% titanium dioxide to form a first precursor (1); 2.

Characteristically, the differential roller (22) is made up of a rubber roller (221) and a metal embossed roller (222). When the first precursor (1) passes the embossed part (222b) of the metal embossed roller (222), the speed is 7884M/min, and when the first precursor (1) passes the concave part (222a) of the metal embossed roller (222), it does not contact with the rubber roller (221), and the speed is 8996M/min; 3.

S5 Air pressure spraying: Through a middle feeding roller (5) with a speed of 125135M/min, the cotton-feel textured yarn after false twisting and deforming is conveyed to a nozzle (6) of 7585 knot/m for spraying, thus forming a single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC).

(7) For better understanding and recognition of the present invention, the technical means of the present invention is described in detail below with respect to a preferred embodiment.

(8) Firstly, select a precursor of PET pre-oriented yarn (POY) with residual extension difference of 150%160%, NDR (natural draw ratio) of more than 1.4%, and single filament DPF<0.5, modify it by adding 0.8%-1.2% titanium dioxide, to form a first precursor (1). The PET pre-oriented yarn features strong tenacity, easy stretch, resistance to impact and friction, and can be easily dyed. As the precursor, when added with titanium dioxide, it can generate long-acting UV resistance, and can significantly enhance the UV-resistant property of the final fabric. Then, the first precursor (1) is fed into a flat conveying roller (21) with a speed of 6873M/min, and then fed into a differential roller (22) with a speed of 5964M/min, and then fed into an accelerating roller (23) with a speed of 95102M/min, to form a dark and light double colored textured yarn with linen-like appearance and tone (11). Specifically, the differential roller (22) is made up of a rubber roller (221) and a metal embossed roller (222). When the first precursor (1) passes the convex part (222b) of the metal embossed roller (222), the speed is 5964M/min. When the first precursor (1) passes the concave part (222a) of the metal embossed roller (222), it does not contact with the rubber roller (221), and the speed is 6873M/min. Therefore, after the first precursor (1) is fed into the flat conveying roller (21), the differential roller (22) and the accelerating roller (23), the precursor can generate irregular extension multiples, forming irregular interconnecting dark zones and light zones on the precursor. Thus, through process and machine updating, a dark and light double colored textured yarn with linen-like appearance and tone (11) can be produced from a single-material precursor. Then, the dark and light double colored textured yarn (11) is fed into a heater (3) with the heating temperature of 180 C.200 C. for heating and setting. After heating and setting, the dark and light double colored textured yarn (11) is conveyed to a false twisting machine (4) and is processed at a twist degree of 22002500 T/M, forming a cotton-feel textured yarn. Then, through a middle feeding roller (5) with a speed of 125135M/min, the cotton-feel textured yarn after false twisting and deforming is conveyed to a nozzle (6) of 7585 knot/m for spraying, forming a single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC). Specifically, the false twisting machine (4) uses a modified Mitsubishi ST-5 pin type. Thus, through the above machine and process updating, after modification and false twisting, the single-material PET pre-oriented yarn can be made into a single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC) with linen-like appearance and tone, high elasticity, UV resistance, moisture absorbing and quick drying properties, as well as the feel of cotton.

(9) Another preferred embodiment is used below to describe the technical means of the present invention:

(10) Firstly, select a precursor of PET pre-oriented yarn (POY) with residual extension difference of 160%, natural draw ratio (NDR) of more than 1.4%, and single filament DPF=0.4, modify it by adding 1.0% titanium dioxide by means of polymerization processing, so as to form a long-acting UV-resistant first precursor (1); then, the first precursor (1) is fed into a flat conveying roller (21) with a speed of 72M/min, and then into a differential roller (22) with a speed of 62M/min, and then into an accelerating roller (23) with a speed of 100M/min, to form a dark and light double colored textured yarn with linen-like appearance and tone (11). Specifically, the differential roller (22) is made up of a rubber roller (221) and a metal embossed roller (222). When the first precursor (1) passes the convex part (222b) of the metal embossed roller (222), the speed is 62M/min. When the first precursor (1) passes the concave part (222a) of the metal embossed roller (222), it does not contact with the rubber roller (221), and the speed is 72M/min. Thus, when the first precursor (1) is fed into the flat conveying roller (21), the differential roller (22), and the accelerating roller (23), the precursor will generate irregular extension multiples, producing irregular interconnecting dark zones and light zones on the precursor. Through the improvement of manufacturing processes and machines, a dark and light double colored textured yarn with linen-like appearance and tone (11) can be produced from a single-material precursor. Then, the dark and light double colored textured yarn (11) is fed into a heater (3) with the heating temperature of 190 C. for heating and setting. After heating and setting, the dark and light double colored textured yarn (11) is conveyed to a false twisting machine (4) and is processed at a twist degree of 2400 T/M, to form a cotton-feel textured yarn with linen-like appearance and tone, high elasticity, and moisture absorbing and quick drying properties. Then, through a middle feeding roller (5) with a speed of 130M/min, the cotton-feel textured yarn after false twisting and deforming is conveyed to a nozzle (6) of 80 knot/m for spraying, to form a single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC). Thus, through the above machine and process upgrading, after modification and false twisting, the single-material PET pre-oriented yarn can be made into a double-colored cotton-feel single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC) with high elasticity, moisture absorbing and quick drying properties, UV resistance, linen-like appearance and tone. Then, using the single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC) as a warp, and using the single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC) with proportional addition of a regenerated fiber (RePreve) as a weft, a fabric can be woven out. The warp is 170(D)/144(F) single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC), and the weft is made of 170(D)/144(F) single-material irregular extension multiple long-acting functional textured yarn (7) (PRKHC) with addition of 75(D/2)/144(F) RePreve environmental fiber. The functional fabric is formed by weaving the warp and weft at warp density of 111 (Picks/inches) and weft density of 103 (Picks/inches). The functional fabric contains 22% regenerated fiber (RePreve). Finally, after dyeing and finishing, the functional fabric can have linen-like appearance and tone. The finished product is a cotton-feel irregular extension multiple long-acting functional fabric ((Cloth No.: B1149, Specification: warp density 111 (Picks/inches), weft density 103 (Picks/inches), width 57, weight 265 g/y)).

(11) Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
