Abstract:

Corona discharge, constituting one of the forms of atmospheric plasma, is a pro-ecological alternative to many conventional processes of the wet treatment of textiles that can also assist in improving these processes. However, one has to adapt the characteristics of corona discharge to the properties of the textiles to be treated and to use this plasma under controlled conditions, optimised to the results expected. An appropriate generator was designed and built equipped with a special multi-point electrode which makes it possible to obtain the extent of surface layer modification expected without any deterioration in the original strength properties of the textiles. The treatment of synthetic fabrics with corona discharge using the generator developed under optimised process conditions, brings about physical and chemical changes in the structure of the surface layer, resulting in a considerable modification of the surface strength and performance properties of textiles. The paper discusses changes in the properties of three selected types of woven fabrics from polyester, polyamide and polypropylene fibres treated with corona discharges, including wettability, the bonding strength of laminated fabrics, as well as the water-tightness and resistance of pigment printed fabrics for multiple washing. The results obtained confirm the usefulness of the preliminary treatment of textiles with corona discharge in improving their quality.
