| titleOfInvention | Photochromic composite fiber |
| abstract | The invention provides a photochromic composite fiber, which comprises a skin layer and a core layer, wherein the skin layer is a fiber-forming polymer, a proper amount of a flame retardant, a softener and an air tightness improver are added, the core layer is a thermoplastic fiber-forming polymer, and a photochromic dye, an antioxidant, a spinning aid, a thermal stabilizer and a sensitizer are added according to a certain proportion. The fiber is characterized in that a photochromic material and a functional additive are doped in a core layer material, a skin-core composite structure is constructed through melt spinning, and the core layer is encapsulated by a skin layer containing a functional additive, so that the stability of the photochromic material in the core layer material is improved, and the ultraviolet ray is higher than 4000 mu W/cm 2 The color change capability of the material can be maintained for 70-110 hours under the normal condition of temperature of 40 ℃ and humidity by accelerated aging test, and the material has the advantages of excellent photochromic property, quick response time, strong repeatability, long service life, excellent mechanical property and the like. |
