The invention discloses a quilt with a temperature self-adjusting function and relates to the field of daily supplies. The quilt comprises quilt surfaces and filler arranged in the quilt surfaces in a filling manner and is characterized in that the quilt surfaces are fabric prepared through blending of viscose fibers and Outlast acrylic fibers containing phase-change materials, the filler material is prepared through blending of polyester filaments and Outlast acrylic fibers containing the phase-change materials, and the filler fibers adopt a concave-convex structure. Compared with the prior art, the quilt has thermal insulation properties and also has the light and fashionable characteristics; meanwhile, the quilt surfaces are prepared through blending of the acrylic fibers, the viscose fibers and the phase-change materials and have the advantages of acrylic fibers and the viscose fibers, namely, the advantages including fluffing, softness, fullness, thermal insulation, light weight, soft hand feel, smoothness, good moisture absorption performance, skin friendliness and comfort; air gaps of the filler structure of the quilt can form a capillary effect and can rapidly guide water, dryness of the quilt is kept, and breeding of microorganisms is avoided.
