Luminescence and Mechanical Properties of Photoluminescent Core Bicomponent Fibers

Photoluminescent fibers with a sheath-core morphology are produced to impart good mechanical properties. Both photoluminescent and mechanical properties are examined for these fibers with respect to photoluminescent pigment concentrations in the core, draw ratios, and polymer types. The photoluminescent pigment concentration in the core of the fibers directly influences their luminance intensity and afterglow properties as well as their mechanical properties.
