The invention discloses high-elasticity warm healthy knitted fabric, which comprises a surface layer, a middle layer and an inner layer. The surface layer is formed with hollow polyester fibers and high-count shrink-proof wool yarns, the inner layer comprises hollow cotton fibers and animal fibers, the animal fibers comprise one or two of wool, cashmere, cony hair and angora, the middle layer comprises twisted yarns of a plurality of polyester filaments and a spandex yarn, the surface layer and the inner layer are connected through the twisted yarns in different patterns, the twisted yarns are formed via compounding and twisting of one spandex yarn and 3-5 polyester filaments, and the twisting coefficient is 320-450. By adopting the technical scheme, the high-elasticity warm healthy knitted fabric is light and thin. A large amount of static air can be provided in the middle of the fabric layer due to patterned connection of the surface layer and the inner layer, and the heat transfer between the inner layer and the outer layer can be blocked to achieve the purpose of good warmth. Due to the structure with the hollow cotton fibers in the inner layer, the fabric has a good moisture diffusion performance. Since the high-mount shrink-proof wool yarns are adopted in the surface layer and the polyester-spandex composite yarns are adopted in the middle layer, the elasticity of the fabric is improved.
