REVIEW ON SIGNIFICANT CHARACTERISTICS OF FUNCTIONALIZED TEXTILE PRODUCTS
Abstract
The modern society is in a permanent transformation, therefore the textile industry has to continuously change and adapt their processes and products to be environmental friendly and to meet customer expectations in the today’s highly technologized world. In order to meet the requirements of the actual needs of society and the technological progress, the concept of the textile products has evolved, nowadays providing benefits in a variety of application such as comfort, healthcare, protection, agriculture, information, transportation, military equipment, sporting and outdoor products etc. Functionalisation of textiles represents the process that grant to textiles properties beyond the aesthetic and decorative attributes. The paper presents textiles with multiple functionalities such as fibres, yarns and textile structures and their significant characteristics: water repellency/vapour permeability, heat transfer, camouflage effect, ecotoxicological properties, antimicrobial activity and flammability. The assessment of efficiency of these characteristics is performed by modern and reliable physical and chemical procedures: measurement of water vapour resistance of textiles, determination of thermal resistance, spectral reflectance measurement in infrared range, phthalates determination by gas chromatography, determination of certain carcinogen aromatic amines by high performance liquid chromatography and gas chromatography. There are processes conducted in textile industry, from the fibre stage to fabric, that are harmful to environment. In this context, sustainability of textile industry implies manufacturing not only of competitive products but also environmentally friendly and safety products. Therefore, the content of potentially hazardous chemicals (e.g. azo dyes, formaldehyde, phthalates, pesticides, chlorinated phenols etc) is limited in finished textile.
