20.500.12556/DKUM-68159 Določitev formaldehida v različnih tekstilnih izdelkih Determination of formaldehyde in different textile products Namen diplomskega dela je določiti vsebnost formaldehida v izdelkih iz celuloze, ki jih ponujajo različne trgovine s tekstilnimi izdelki. Obstaja namreč velika verjetnost, da se omenjena škodljiva spojina nekontrolirano vgrajuje v material, kot posledica neizogibno potrebne obdelave za dosego odpornosti tekstilnih materialov na mečkanje. Sklepa se, da bo vsebnost formaldehida v nižje cenovnih izdelkih višja v primerjavi z izdelki višjega cenovnega razreda. Materiali, obdelani proti mečkanju, velikokrat vsebujejo preko 1000 in celo preko 2000 ppm prostega formaldehida ali formaldehida, ki se sprošča pri hidrolizi za katerega vemo, da je potencialno kancerogen. V ta namen smo uporabili metodo za preskušanje formaldehida skladno z veljavnim standardom SIST EN ISO 14184-1. Za vrednotenje učinkovitosti apretur proti mečkanju pa smo uporabili testno metodo Ugotavljanje izravnavanja gub horizontalno nagubanega preskušanca z merjenjem izravnalnega kota skladno z veljavnim standardom SIST EN 22313. Glede na dobljene rezultate smo prišli do zaključka, da vsebnost oziroma predpisana omejitev formaldehida ni prekoračena v nobenem vzorcu. The purpose of this thesis is to determine the formaldehyde content in products made from cellulose, which are offered by various stores with textile products. There is a great probability that the aforementioned harmful compound is uncontrollably embedded in the material as a result of the inevitable processing needed for achieving the resistance of textile materials to creasing. It is concluded that the formaldehyde content will be higher in lower priced products compared to higher-priced products. Materials, which are processed to prevent creasing, often contain more than 1000 and even more than 2000 ppm of free formaldehyde or formaldehyde, which is released during hydrolysis and is known to be potentially carcinogenic. For this purpose, we used the method for testing formaldehyde in accordance with the applicable SIST EN ISO 14184-1 standard. In order to evaluate the effectiveness of anti-creasing finishes, we carried out the test method Determining the levelling of creases of a horizontally wrinkled specimen by measuring the angle of recovery in accordance with the applicable SIST EN 22313 standard. Based on the obtained results, it is concluded that the content or rather the prescribed limit of formaldehyde was not exceeded in any of the samples. formaldehid celuloza nagnjenost k mečkavosti kot poravnave DMDHEU formaldehyde cellulose tendency to crease angle of recovery DMDHEU true true false [B.
