摘要

At present polypropylene is one of polymers used the most frequently to manufacture such materials as textile, technical and bicomponent fibres, nonwovens, foils and tapes. Polypropylene fibres find wide application possibilities in textile and automotive industry due to their properties (low specific weight, good transport and insulation properties as well as low price). A disadvantage of polypropylene fibres is a fact that they are not surface dyeable. A solution can be chemical or physical modification of the polypropylene polymer. We would like to show in our paper a possibility of surface dyeing of polypropylene fibres using physical modification of the polypropylene polymer on spinning. Several modifiers were proposed and developed in the frame of our research works focused on study of properties of polypropylene polymer from a viewpoint of physical structure, surface dyeability and spinning with the aim to increase affinity of polypropylene fibre to dyestuff on surface dyeing of the fibre. Influence of new types of modifiers on improvement of surface dyeing of polypropylene fibres and workability of the modified polypropylene filaments was evaluated and compared with properties of polypropylene fibres modified using commercionally available modifiers.
