Zusammenfassung:The invention relates to a thermal insulation basalt fiber covering yarn and a preparation method and application thereof in the technical field of covering yarns. The core yarn in the core-spun yarn is basalt fiber, and the outer wrapping fiber is heat-regulating energy-storing nanofiber with a skin/core structure; wherein a core material in the heat-regulating and energy-storing nanofiber is an acrylic acid n-alkyl ester polymer, and a skin material is an acrylonitrile-vinylidene chloride copolymer. The core material of the outer wrapping fiber in the heat-preservation basalt core-spun yarn is the phase-change material n-alkyl acrylate polymer and has excellent heat storage performance, so that the prepared heat-preservation basalt fiber core-spun yarn has excellent static air adsorption capacity and good heat preservation performance, and the temperature adjusting time is prolonged. Meanwhile, the preparation method of the core-spun yarn is easy to operate and low in cost, and the prepared core-spun yarn i
