摘要

Polypropylene (PP) doesn't contain functional groups; therefore dyeing in the mass by pigments is used in the dyeing of PP fibres. Dispersants are used to improve dispergation, increasing the homogeneity of the masterbatches. In this work, the influence of three types of dispersants on the processability and processing properties of protective photoluminescent pigment of PP masterbatches as well as the effect of dispersants on the resulting structural and mechanical properties of modified PP fibres were studied. Dispersants D1 and D2 (polyethylene waxes) weren't significantly demonstrated in the preparation of masterbatches, while dispersant D3 (N, N-bis-stearyl ethylenediamine) affected the melt flow index of the resulting masterbatches. The modified PP fibres with the protective photoluminescent pigment were prepared from masterbatches and PP by the discontinuous process of the spinning and drawing associated with the false-twist texturing of the fibres. The influence of dispersants on the resulting properties of the fibres didn't manifest itself significantly.
