Abstract:Glavna tema magistrske naloge je izolacija gradnikov jajčnih lupin kokoši in prepelice ter obdelava sintetičnih (poliester, PES) ter naravnih (bombaž) tekstilij z le-tem. Izbira teme je temeljila na pogledu na jajčne lupine kot odpadek in hkrati kot uporabno surovino, ki lahko izboljša lastnosti drugih surovin oz. materialov, pri tem pa lahko ustvarimo napredek na področju ognjevarnih, medicinskih ter UV-zaščitnih oblačil. V nalogi smo preverjali izbrane funkcionalne lastnosti vodne raztopine jajčnih lupin, kot so: velikosti delcev in zeta potencial, pH vrednost, motnost, površinska napetost, stični kot, električna prevodnost in antioksidativnost; ter analizirali učinkovitost obdelave poliestrnih (PES) in bombažnih tkanin s pridobljenimi raztopinami, pri čemer smo uporabili napredne preparativne (hidrotermična razgradnja- hidroliza) in analitske metode (merjenje pH, spektroskopija). Ugotovili smo, da je vzorec v obliki vodne raztopine pokazal dobre lastnosti na področju površinske lastnosti, prav tako je pokazalo dobre rezultate pri meritvah zeta potenciala ter pri merjenju električne prevodnosti. Pri obdelanih PES in bombažnih vzorcih s to raztopino jajčnih lupin, pa lahko poudarim, da so bili vidni rezultati na področju ognjevarnosti, protimikrobnosti in UZF. Rezultati sicer niso bili izraziti, ampak bili opazni in so mejili v dobro smer.

Title:Functionalization of textiles using building blocks isolated from eggshells and nano-fibre production
Abstract:The main topic of the master thesis is the insulation of eggshell building blocks of hens and quails and the treatment of synthetic (polyester, PES) and natural (cotton) textiles with them. The choice of the topic was based on the view of eggshells as a waste and at the same time as a useful raw material that can improve the properties of other raw materials or materials, with the potential to create advances in the field of fire-resistant, medical and UV-protective clothing. In this thesis, selected functional properties of aqueous eggshell solution, such as: particle size and zeta potential, pH value, turbidity, surface tension, contact angle, electrical conductivity and antioxidant capacity, were tested; and the performance of polyester (PES) and cotton fabrics treated with the obtained solutions was analysed using advanced preparative (hydrothermal degradation-hydrolysis) and analytical methods (pH measurement, spectroscopy). We found that the sample in aqueous solution form showed good performance in the area of surface properties, as well as good results in zeta potential measurements and electrical conductivity measurements. However, for the PES and cotton samples treated with this eggshell solution, it can be pointed out that results in the areas of refractoriness, antimicrobial activity and SPF were evident. Although the results were not pronounced, they were noticeable and bordered in a good direction.
