Preparing Method of Photochromic Filament Which Changes Its Colors By Photochromism, Photochromic Filament Prepared Thereby, Fancy Yarn, Embroidery Yarn, Woven Fabric And Knitted Fabric Comprising The Same

摘要

Durability and light-fastness is excellent, and relates to a method for producing the photosensitive reversible photochromic being photochromic in color in the colored filaments, this suggests a photochromic filament fan using the same made according (fancy yarn), embroidery, woven and knitted fabrics . At 180 ~ 220 ℃ including polypropylene chips 55-93 wt%, 0.5-5 wt% of photochromic dye, 1-15% by weight of an antioxidant, a light stabilizer and 5 to 20% by weight of a fluorine compound 0.5-5% by weight and a master batch composed of the average particle diameter of 1 to 200 mesh sand, comprising: a primary radiation in an extruder and extruded through the pack at least a nozzle hole diameter 0.5㎜ producing a master batch chip; And 180 to the polypropylene chips 65-85% by weight, 10 to 30% by weight of the master batch chip and a UV light stabilizer a mean particle size of the sand batch and blended with 5% by weight and 1 to 200 mesh, diameter of the hole in the detention 220 ℃ the 0.5㎜ 2 in from the extruder through the extrusion and spinning step or more packs photochromic filament (filament) manufacturing method comprising a to and thus the photochromic filaments, fans suggests containing the same produced in accordance, woven, knitted and photochromic Saga filament strand 2, the TPM to the CS 150 denier × 2 consensus 500-600 embroidery is provided. Photochromic and the filament yarn (yarn) and a fabric containing the same of the present invention is not only excellent in light discoloration resistance, has an excellent durability and light-fastness.
