Abstract

The invention relates to a rare earth yttrium oxysulfide red long afterglow polyamide luminescent fiber and its manufacture method, the luminescent fiber is composed of 90-96wt% of polyamide spinning raw material, 3-10wt% of rare earth yttrium oxysulfide luminescent material and less than 1wt% of nano-function auxiliary agent. The preparation method comprises the following steps: mixing luminescent master batch prepared by the above raw materials and polyamide slices in proportion, after drying for a certain time and a certain temperature, using a screw extruder for spinning and reeling through a special spinning technology to prepare POY filament, and texturing the POY filament to prepare DTY filament or preparing the FDY filament through drafting. The polyarmide fiber prepared by the method can emit the red afterglow with wavelength of 600-750nm after irradiation under daylight or fluorescence, the afterglow initial brightness is 2-3cd / m<2>, the afterglow life can reach 4-6 hours, the luminescent fiber is innocuous and unpoisonous, and has no adverse influence on human body and 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 polyamide luminescent 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 industrial...
