Preparation method of temperature-sensing sun-flavor slow-release fiber

The invention discloses a preparation method of temperature-sensing sun-flavor slow-release fibers, and relates to the technical field of functional fibers. According to the functional fiber, sun monosodium glutamate oil and a phytantriol lipid material are blended to form a reverse phase lyotropic liquid crystal which serves as a core layer solution, a poly (N-isopropylacrylamide)/natural polymer blended solution serves as a skin layer solution, and the functional fiber with a skin-core structure is obtained through a coaxial spinning technology. The sun-flavor essential oil is successfully compounded, and people can feel relaxed and pleasant due to the flavor; the'sun smell 'slow-release fiber with the lyotropic liquid crystal core layer is prepared, liquid crystal phase change of the core layer and pore channel phase change of the skin layer are caused on the basis of temperature change, 'sun smell' release is adjusted, the effect that the fabric is irradiated by sunlight to release'sun smell 'in reality i
