Abstract
The ability to sorb the liquid phase (sorption) presents very important textile fibres’ property. Regenerated cellulose fibres are in general hydrophilic but in order to improve their reactivity respectively the sorption ability that plays an important role in further stages of fibres’ treatment, the common standard pre-treatment processes are used. The standard treatment procedures cause beside the chemical-technological and mechanical-technological effects also the ecological waste-water pollution. In order to fulfil the European standards it would be reasonable to improve the fibres’ reactivity using the plasma technique which according to the environment represents an alternative to the standard chemical treatment procedures or can be a part of such treatment. The application of plasma technique in the field of textile fibres is in his earliest stage, so the initiation of mentioned technique would present an important technological novelty in the field of the orientated polymers. According to this, the projects’ purpose is first to do the systematically research and to analyze the plasma treatments’ influence on the fibres’ surface like as on the applicative properties of the fibres. In order to do that, the investigation about if plasma treatments’ beside ecological faultless offers also a satisfactory results about fibres’ reactivity, would be carried out. The fibres’ reactivity reflects like changed surface free energy and plays an important role beside in the wetting processes also in further treatment processes and serves as an “indicator” of the polymer materials’ surface nature. According to that, the tensiometry a measuring technique would be applied, which in the field of orientated polymers represents an innovative approach inn estimating the fibres’ reactivity. Our contribution in the field of analyzing differently surface treated fibres is to choose the appropriate range of best liquids for measuring the contact angles between them and the fibres and to determine the suitable theory and mathematical procedure for calculation the fibres’ surface free energy. Further the precisely determination of the acid-base fibres’ character would be done and also the comparison about the amount of the acid groups determination using the titration methods and acid-base fibres’ character defined using the tensiometry would be performed. The main projects’ goal is, on the base of performed measurements, analyses and carried out theories, to define the procedures and recommendations for successful application of plasma treatment as an up-to-date and ecological more faultless procedure in the field of fibres’ treatment processes.
