Structure and Properties of Polypropylene Fibres Modiffed with Photoluminescent Pigment as a Tool for the Protection of Original Products
Abstrak
A special photoluminescent inorganic pigment was used as a tool to protect polypropylene (PP) fibre originality. The effect of pigment content and uniaxial deformation on the supermolecular structure and basic mechanical properties of PP fibres modified with the above-mentioned pigment were investigated, together with its colour performance under a UV lamp. Supermolecular structure parameters, such as birefringence, sound velocity in fibres, crystallinity and the crystallinity index of undrawn and drawn modified PP fibres prepared using a discontinuous technological process, were studied. Mechanical properties such as fi neness, Young’s modulus, tenacity at break and elongation at break of undrawn and drawn modified fibres were evaluated. The obtained experimental results of modified PP fibres were compared with the supermolecular structure and mechanical characteristics of standard unmodified PP fibres prepared under same technological conditions.
