Study on the Photochromic Properties of Coloured Luminous Fibres Based on PA6
Journal Title: Fibres and Textiles in Eastern Europe - Year 2016, Vol 24, Issue 3
Abstract
Coloured PA6 luminous fibres were prepared by adding luminous material and inorganic pigments. The morphology and optical properties of the coloured PA6 luminous fibres were characterized. The results revealed that luminous materials were dispersed uniformly in the fibres without obvious agglomerates. The yellow inorganic pigment and luminous material might induce a reduction in the PA 6 fibre crystallization degree. The luminous fibres emitted long-lasting phosphorescence with an excitation peak at 360 nm and emission peak at 515 nm. However, the excitation spectrum of the PA6-Y exhibited three peaks. The decay curves revealed that the yellow inorganic pigment enhanced the brightness of PA6 luminous fibres. The PA 6 luminous fibres had low colour purities and a high colour rendering index. There was no obvious difference among the emissive colours of the luminous fibres, and the colours of luminous fibres were similar to those of the pigments added.
