Abstract: The invention discloses a preparation method of shape memory hollow fiber. A shape memory polymer is synthesized into the shape memory hollow fiber through the wet spinning, dry spinning, melt spinning, reaction spinning, gel spinning and composite spinning technology. The shape memory polymer is shape memory polyurethane. The shape memory polyurethane is synthesized from three starting raw materials: long-chain polyhydroxy compound, diisocyanate and chain extender, wherein the diisocyanate and chain extender are used as a hard fragment, and the long-chain polyhydroxy compound is used as a soft fragment. The preparation method of the shape memory hollow fiber disclosed by the invention can obtain the shape memory polymer with thermal stimulus sensitivity, and can be applied to thermal management smart textiles, pillow stuffing and comfortable mattress.
