Summary:PROBLEM TO BE SOLVED: To provide a phosphorescent polyurethane polyurea elastic yarn having excellent elasticity characteristics and luminous brightness and excellent designability in hue such as color or color tone and high practicality. SOLUTION: The phosphorescent polyurethane polyurea elastic yarn is obtained by including a phosphorescent agent in a polyurethane polyurea and carrying out dry spinning or a wet spinning method. The average particle diameter of the phosphorescent agent is 1-5 μm and the content of the phosphorescent agent is 5-15 wt.%. Thereby, the elastic yarn having suppressed unevenness and the sufficient luminous brightness is obtained. COPYRIGHT: (C)2006,JPO&NCIPI
