Abstract

The invention relates to an yttrium oxysulfide red long-afterglow polypropylene fiber and a production method thereof. The yttrium oxysulfide red long-afterglow polypropylene fiber is composed of 90-96wt% of polypropylene spinning raw material, 3-10wt% of rare-earth yttrium oxysulfide light-emitting material and less than 1wt% of nano functional auxiliary; the luminescent master batch made from the raw materials are blended with polypropylene slices; then, the mixture is dried at certain temperature for certain time, and then is spun and wound by using a screw extruder through a special spinning process to form POYs (Pre Oriented Yarns); the POYs can be elasticized to form DTYs (Draw Texturing Yarns), or drafted to form FDYs (Full Drawn Yarns). The polypropylene fibers obtained by the method can be excited by daylight or fluorescent light to emit red long-afterglow having the wavelength ranging from 600 to 720nm; the initial intensity of the afterglow ranges from 2cd/m2 to 3cd/m2; the life of the afterglow can be 4-6 hours; the light-emitting fibers are nontoxic and harmful, and have no adverse effect on the human body and the environment.

Description

technical field [0001] The invention relates to the field of textile products and technology, in particular to a rare earth yttrium oxysulfide red long-lasting polypropylene luminous fiber and a preparation process thereof. Background technique [0002] Long afterglow luminescent fiber, also known as luminous fiber, is a kind of light-induced energy storage type made of polyester, nylon or polypropylene resin by adding rare earth long afterglow luminescent materials and nano-scale functional additives through special spinning technology. Glowing fibers. The fiber is green, environmentally friendly and energy-saving, and can be widely used in aviation and navigation, defense industry, building decoration, transportation, night work and clothing and other fields. The currently produced luminous fibers mainly emit blue and yellow-green light, and their luminous properties such as luminous brightness and afterglow time have met the needs of practical applications, and industria...
