Soapnut shells and effectiveness of laundering

V diplomski nalogi smo proučili nego tekstilij z alternativnim pralnim sredstvom, pralnimi oreščki. Analiza objavljenih člankov kaže na dejstvo, da je vrednotenje učinkovitosti odstranjevanja nečistoč in mikroorganizmov s pomočjo pralnih oreščkov dokaj slabo raziskano. Namen diplomske naloge je bil ovrednotiti učinkovitost odstranjevanja nečistoč ter mikroorganizmov s pralnimi oreščki pri različnih pogojih pranja. Prav tako smo želeli ugotoviti vpliv temperature kopeli in časa pranja na koncentracijo izločenih neionskih tenzidov iz pralnih oreščkov. V eksperimentalnem delu so predstavljene lastnosti uporabljenih materialov, uporabljenih postopkov ter metode dela in aparati. Ugotovili smo, da je bilo pralno sredstvo IEC bolj učinkovito pri odstranjevanju madežev kot pralni oreščki. Ugotovili smo tudi, da pralni oreščki nimajo razkuževalnega učinka proti bakteriji Enterococcus faecium in da je odstranjevanje nečistoč s pralnimi oreščki.In this thesis we examined the treatment of textiles with an alternative detergent, soap nuts. Analysis of published articles reflects the fact that the evaluation of the effectiveness of removing soil and microorganisms by soap nuts is poorly studied. The aim of the thesis was to evaluate the effectiveness of removal of soil and microorganisms by soap nuts under different washing conditions. We also wanted to determine the effect of temperature of baths and washing time on the concentration of elimination non-ionic surfactants in soap nuts. The experimental section presents the characteristics of the used materials, procedures and equipment. It was found that the detergent IEC was more effective in soil removal than soap nuts. It was also found that soap nuts did not exhibit a disinfection effect against the bacteria Enterococcus faecium
