Abstract

The invention relates to the manufacture field of chemical polyester fibers, relating to a luminous material, in particular to a color luminous polyester plastic piece and a manufacture method of short fibers thereof. The luminous material belongs to an aluminate fluophor series of rare-earth Eu, uses strontium aluminate or calcium aluminate as a substrate, adds a rare-earth Eu as an activator and adds mid-heavy rare earth of Dy or Nd as auxiliary activators. EBS (Ethylene Bis Stearamide) is used as a dispersant. The luminous compound adopted by the invention is a self-luminous material of rare-earth aluminate and has the advantages of long illumination time, strong brightness, stable chemical properties without toxicity, harm or radioactivity, and the like. After being illuminated by natural light or fluorescent light for 10-20 min, the product can continuously illuminate for 6-10h in dark and be repeatedly used without limit.

Description

technical field [0001] The invention relates to the field of chemical polyester fiber manufacturing, in particular to designing a luminescent material, in particular to a method for manufacturing colored luminescent polyester plastic parts and short fibers thereof. Background technique [0002] Seeking to develop new energy sources and light sources has become the common pursuit of people in the world today. With the maturing of optoelectronic technology, many countries have turned their research focus to realize the light-to-light conversion of materials, that is, light storage materials. [0003] The first and second-generation luminescent materials have certain limitations in their application fields due to their toxicity and radioactivity to the human body, as well as the disadvantages of low luminance and short duration. The third generation of light-storing materials came out in the 1990s, mainly rare earth aluminate series of light-emitting materials, which have the ...
