The basic raw material for the production of textile products and semi-finished products are fibres which are separated according to their origin, chemical composition, fibre properties and intended use. In order to achieve the desired final properties of textiles, various chemical substances are also used in the process of production and processing of fibres and the manufacture of textile products in order to improve their properties. These are, in addition to colorants, substances that can improve some of the product's properties, such as friability, (in) flammability, water repellency, softness and the like. The use of chemicals in the textile industry can also have a negative impact on human health, since the substances used can enter the body through the skin, orally or by inhalation. Harmful substances can affect our body genotoxically and carcinogenically and cause disruption of the hormonal system. The textile industry is one of the most environmentally unfriendly industries, but increasing public awareness and social responsibility related to environmental issues has led the textile industry to produce products more environmentally friendly. To this end, substances and processes for the production and treatment of fibres, which are not hazardous to the environment and human health, have been started to improve the appearance and appearance of textile products. Textile products containing no harmful substances for the environment and human health shall be appropriately labelled. Eco-labelling has been present on the European market since 1992, and since then it has remained in the market today.
The purpose of the diploma thesis was to investigate the primary school students 'view of the presence of harmful substances in clothing and to formulate guidelines for raising the students' awareness of the problem described.
114 ninth grade students from three different Slovenian elementary schools were included in the survey. The results show that most elementary students are unaware that clothing may contain harmful substances. Most elementary students, however, recognize at least one of the eco-labelling signs, but there is no statistically significant difference in the identification of eco-labels between boys and girls and there is no correlation between the fact that students wear eco-clothing and eco-labelling identification.
