[0023] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] As Figure 1 shown, a warp knitted soft polyester sofa fabric includes: a surface layer 1 and an inner layer 2, and a plurality of phase change sponge bumps 3 are arranged between the surface layer 1 and the inner layer 2.

[0025] The surface layer 1 is woven by a warp knitting machine with three guide bars GB1, GB2, and GB3. GB1 uses the first composite yarn as the knitting thread, GB2 uses the second composite yarn as the knitting thread, and GB3 uses spandex filament as the knitting thread.

[0026] As Figure 2 shown, the first composite yarn includes a core wire and a wrapping wire spirally wound around the outside of the core wire. The core wire is a polyester filament 11, and the wrapping wire includes cotton fiber yarn 12 and milk protein fiber yarn 13 arranged in a 1:1 ratio. The polyester filament 11 has high strength and good deformation resistance, which can improve the overall strength of the fabric. The cotton fiber yarn 12 and the milk protein fiber yarn 13 have a soft and comfortable hand feeling, which can improve the softness and comfort of the fabric. Preferably. The polyester filament 11 used in the first composite yarn is a fluorescent polyester filament, so that the fabric has fluorescent characteristics. The fluorescent polyester filament is prepared by mixing and melt-extruding a fluorescent functional masterbatch and PET chips.

[0027] As Figure 3 shown, the second composite yarn is formed by twisting and doubling sisal fiber yarn 14 and polyester filament 11. The sisal fiber yarn 14 is spun from sisal fiber and has various advantages such as toughness, tear resistance, and wear resistance. Combined with the polyester filament 11, it can improve the strength of the surface layer 1 and the overall fabric, and is beneficial to extending the service life of the sofa fabric. Preferably, the polyester filament 11 used in the second composite yarn is a temperature-sensitive color-changing polyester filament, which can change color with the room temperature, improving the beauty and texture of the sofa fabric. The temperature-sensitive color-changing polyester filament is prepared by melt spinning a temperature-sensitive color-changing masterbatch and polyester chips.

[0028] At the same time, as Figures 5 to 7 shown, the organizational structure of GB1 is 3-2 / 4-5 / 2-1 / 4-5 / 1-0 / 3-4 / / , and the yarn feeding rule is to feed one yarn and skip one. The organizational structure of GB2 is 3-4 / 2-1 / 3-4 / 1-0 / 4-5 / 3-2 / / , and the yarn feeding rule is to feed one yarn and skip one. The organizational structure of GB3 is 1-0 / 4-5 / 1-0 / 4-5 / 1-0 / 4-5 / / , and the yarn feeding rule is full feeding.

[0029] The inner layer 2 is formed by the interweaving of warp yarns and weft yarns, and both the warp yarns and the weft yarns adopt the third composite yarn.

[0030] As Figure 4 shown, the third composite yarn is formed by the twisting and doubling of polyester filaments 11, nylon filaments 15, and ramie fiber yarns 16. Both the polyester filaments 11 and the nylon filaments 15 have high strength and high anti-deformation ability, which can improve the durability of the sofa fabric; the ramie fiber yarns 16 have the function of antibacterial and mildew prevention, which can reduce the probability of mildew inside the sofa fabric. Preferably, the polyester filaments 11 used in the third composite yarn are antibacterial polyester filaments, and the nylon filaments 15 are antibacterial nylon filaments. Selecting antibacterial polyester filaments and nylon filaments can improve the antibacterial and mildew prevention performance of the inner layer 2.

[0031] Furthermore, in order to improve the anti-puncture ability and strength of the fabric, in this embodiment, the third composite yarn used for the warp yarns and weft yarns of the inner layer 2 is externally wound with ultra-high molecular weight polyethylene fiber yarns. The ultra-high molecular weight polyethylene fiber yarns are spun from ultra-high molecular weight polyethylene fibers, and have the characteristics of high modulus and high strength, which can improve the overall strength of the sofa fabric, and at the same time endow the sofa fabric with anti-puncture ability, prevent sharp objects from piercing the sofa fabric, and can protect the inner filling of the sofa.

[0032] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
