DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, a photosensitive color-changing printed fabric comprises: a printing layer 1, a surface layer 2, an inner layer 3 and a warm-keeping layer 4.

[0021] The surface layer 2 is arranged on one side of the inner layer 3, and the printed layer 1 is printed on the side of the surface layer 2 away from the inner layer 3. The thermal insulation layer 4 is arranged between the surface layer 2 and the inner layer 3. When the clothing is made, the inner layer 3 is the side close to the human body.

[0022] The printing layer 1 includes a first area and a second area, the first area uses a photochromic printing paste, and the second area uses a thermochromic printing paste. Preferably, the first area and the second area do not overlap with each other and can be any pattern. The two areas change color under the action of light and heat, respectively, so that the printing layer 1 presents various colors, which can improve the fashion and aesthetics of the fabric. Further, under a certain environment, the color of the first area and the second area of ​​the printing layer 1 is the same as the color of the surface layer 2, showing a pattern hiding effect. Under another condition, the color of the first area / the second area is consistent with the color of the surface layer 2, so that the fabric only presents the pattern of the second area / the first area, showing a single pattern hiding effect.

[0023] Wherein, the surface layer 2 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and the weft yarns are second composite yarns. Figure 3 As shown, the second composite yarn includes a core yarn and a wrapping yarn spirally wound around the outside of the core yarn, the core yarn is formed by twisting bamboo fiber yarn 12 and ramie fiber yarn 14, and the wrapping yarn is a fluorescent polyester filament 15. The bamboo fiber yarn 12 has the functions of moisture absorption and breathability, antibacterial and anti-ultraviolet, and the ramie fiber yarn 14 has antibacterial and mite removal, moisture absorption and breathability, toughness and anti-ultraviolet performance. The core yarn made by twisting the two has good air permeability and excellent antibacterial performance. The fluorescent polyester filament 15 is made by mixed melt spinning of fluorescent components and polyester chips, which not only has the characteristics of polyester being strong and durable, but also has a fluorescent effect, further improving the fashion and beauty of the fabric.

[0024] Preferably, in this embodiment, the core yarn of the second composite yarn is formed by twisting two bamboo fiber yarns 12 and one ramie fiber yarn 14 together.

[0025] The inner layer 3 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and the weft yarns are first composite yarns. Figure 2 As shown, the first composite yarn includes a core wire and a wrapping wire spirally wound around the outside of the core wire, and the core wire includes a polyester filament 11 and a bamboo fiber yarn 12 cross-wound around the outside of the polyester filament 11. The wrapping wire is a phase change temperature regulating viscose fiber yarn 13. The polyester filament 11 can maintain a certain strength of the inner layer 3, the bamboo fiber yarn 12 makes the inner layer 3 have good air permeability and antibacterial properties, and the phase change temperature regulating viscose fiber yarn 13 has soft and comfortable, moisture-absorbing and breathable, and intelligent temperature regulating functions, making the inner layer 3 more skin-friendly and comfortable. The phase change temperature regulating viscose fiber yarn 13 is spun from a viscose spinning stock solution to which shape-changing temperature regulating microcapsules are added. Preferably, the polyester filament 11 is an antibacterial polyester filament to improve the antibacterial properties of the inner layer 3.

[0026] The thermal insulation layer 4 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and the weft yarns are made of third composite yarns, such as Figure 4As shown, the third composite yarn includes a core wire and a wrapping wire spirally wound around the core wire, the core wire is a hollow polyester yarn 16, and the wrapping wire is an acrylic fiber yarn 17. The hollow inside of the hollow polyester yarn 16 can improve the thermal insulation performance, and the acrylic fiber yarn 17 makes the thermal insulation layer 4 have good thermal insulation.

[0027] 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.
