[0036] S5, carding and slivering: the cotton roll is carded into mixed card slivers by a carding machine with the following process parameters: a relative air humidity of 55-70%, a cylinder speed of 300-350 r/min, a licker-in speed of 720-780 r/min, a doffer speed of 15-25 r/min, and a specified weight of the mixed card sliver of 20-25 g/5 m. [0037] S6, drawing: the mixed card slivers are prepared into a mixed drawn sliver through three passes of drawing with a relative air humidity of 55-70%; and each pass of drawing is performed, with a linear speed of front roller of 160-260 m/min, a roller gauge of 8 mm?6 mm?14 mm 4-8 mixed card slivers, a total draft multiple of 6.5-10.0, and a specified weight of the mixed drawn sliver of 15-18 g/5 m.

[0041] The multifunctional temperature-adaptable yam is obtained through the above-mentioned steps. A knitted fabric or a woven fabric prepared from the multifunctional temperature-adaptable yarn is then used to produce a textile for practical use.

[0042] In this example, the temperature-adaptable fiber used is TEMPSOLUTION? constant temperature fiber purchased from Qingdao Niximi Biological Technology Co., Ltd. The antibacterial fiber used is Freshcot?-collagen fiber purchased from Qingdao Niximi Biological Technology Co., Ltd.

[0045] The process of S5-S9 is unified in Examples 1?4 and the comparative example according to the following standards: [0046] S5, carding and slivering: the relative air humidity is 65%; the cylinder speed is 350 r/min; the licker-in speed is 780 r/min; the doffer speed is 25 r/min; and the specified weight of the mixed card sliver is 22 g/5 m; [0047] S6, drawing: the relative air humidity is 65%; and each pass of drawing is performed with the linear speed of front roller of 200 m/min, the roller gauge of 8 mm?6 mm?14 mm, 6 mixed card slivers, the total draft multiple of 9.0, and the specified weight of the mixed drawn sliver of 16 g/5 m; [0048] S7, roving: the relative air humidity is 65%; the spindle speed is 700 r/min; the total draft multiple is 9.0; the specified rove weight is 6.5 g/10 m; and the roving twist factor is 90; [0049] S8, fine spinning: the relative air humidity is 65%; the speed is 10000 r/min; the total draft multiple is 45; the specified spun yarn weight is 4.6 g/100 m; and the twist factor is 360; [0050] S9, winding: the relative air humidity is 65%, and the winding speed is 1350 m/min.

[0051] The blended yam is tested according to GB/T 3916-1997 and GB/T 3292.1-2008, and test results are as shown in Table 2. The results indicate that in the case of using 50% of the functional fiber, the multifunctional temperature-adaptable yarn obtained in the present disclosure has significantly better physical properties than a regular multifunctional blended yarn.
