Abstract

In this paper, the effect of photochromic pigments on spinnability, drawability and properties of pigmented polypropylene (PP) fibres is presented. The commercial types of PP and photochromic pigment (Photopia® Purple) were used in experimental work to determination of their possibilities in use as a UV sensor fibres. Mechanical properties (tenacity and elongation at break as well as Young’s modulus), thermo-mechanical properties and factor of average orientation of composite fibres were evaluated and discussed. The surface and cross-section of these fibres were monitored using the light microscope. The obtained results indicate the possibility of preparation of the fibres with photochromic pigments in mass.
