摘要
描述了采用母粒注射熔融纺丝生产的长余辉发光涤纶的发光原理。长余辉发光材料的发光原理是:稀土中铕(Eu2+)为激活剂形成发光中心。分析了生产中的技术难点,提出了若干措施。
The shining principles of shining polyester with long afterglow produced by mother pellet injection melt spinning method are described. The shining principles of materials with long afterglow are： Eu^2＋ in rare earth forms shining center for activators. Some technological difficulties in production process are analyzed. Some suggestions are given.
