[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] Combination Figure 1 The present embodiment is described in detail. The memory color-changing wool yarn involved in the present embodiment comprises a core yarn 1, a first covering fiber layer 2 and a second covering fiber layer 3 arranged in sequence; the core yarn 1 is elastic filament, the first covering fiber layer 2 is descaled wool fiber, and the second covering fiber layer 3 is photosensitive color-changing fiber.

[0021] The descaled wool yarn used in this embodiment refers to wool that has been descaled. The surface of wool fibers is covered with a protective lipid layer and hard scales. Although its chemical structure contains a large number of hydrophilic groups, it is difficult for water molecules to interact with wool easily. Therefore, the wool fibers are descaled by chlorine treatment to improve their responsiveness to water. The preferred process parameters and steps for descaling wool treatment are: using an ultrasonic bath (35kHz, 40W) containing sodium hypochlorite (5g / L), hydrochloric acid (1g / L) and nano-calcium carbonate (10g / L), and treating at 37°C for 45 minutes to achieve wool descaling. The descaled wool fibers used have a good warming effect.

[0022] Further, the elastic filament is PTT filament or spandex filament. In this embodiment, PTT filament is selected.

[0023] Furthermore, the photochromic fiber used is a photochromic nylon fiber obtained by melt spinning photochromic azobenzene polyamide, and its cross section is cross-shaped, which has the effect of moisture conduction and perspiration removal.

[0024] Embodiment 2

[0025] Combination Figure 2 The present embodiment is described in detail. The memory color-changing wool yarn of the present embodiment is different from the first embodiment in that a spirally wound wrapping silk layer 4 is arranged between the first wrapping fiber layer 2 and the second wrapping fiber layer 3, and the wrapping silk layer 4 includes aerogel fiber filaments.

[0026] Furthermore, the wrapping filament layer 4 also includes hollow polylactic acid fiber filaments. The spiral winding direction of the hollow polylactic acid fiber filaments is opposite to that of the aerogel fiber filaments. The use of the hollow polylactic acid fiber filaments and the aerogel fiber filaments further improves its warmth retention.

[0027] Embodiment 3

[0028] Combination Figure 3 , this embodiment is described in detail. A knitted fabric involved in this embodiment includes a color-changing fabric layer 10, and the color-changing fabric layer 10 is knitted by the above-mentioned memory color-changing wool yarn. The color-changing fabric layer 10 is specifically knitted by a computer flat knitting machine with a needle number of 12G using memory color-changing wool yarn. During the knitting process, the yarn is first lubricated and waxed, and a new type of yarn storage device is used to strictly control its tension. The preferred weaving machine process parameters are: speed 200 rpm, yarn tension 3.0cN, pulling tension 180cN, and yarn bending depth 3.1mm, so as to avoid problems such as yarn breakage and defects caused by uneven yarn attraction.

[0029] Furthermore, the knitted fabric also includes an antibacterial fabric layer 20 compounded with the color-changing fabric layer 10 through a hot melt adhesive mesh. The antibacterial fabric layer 20 is warp-knitted with antibacterial elastic core-spun yarn; the antibacterial elastic core-spun yarn includes spandex filaments and nano-titanium dioxide catalyst antibacterial fibers coated on the outside of the spandex filaments.

[0030] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
